COMMENT
f you live outside Europe, Japan or the US and are planning on
buying a used excavator over the next few years, beware! If you buy
a machine with an Interim Tier 4 or Stage IIIB-compliant engine
and you don’t have access to ultra low sulphur diesel, you may quickly
end up with a dead machine on your hands.
New laws on diesel engine emissions were introduced in Europe
and the US at the start of the year. Their aim is to cut the amount of
black soot coming out of off-highway machines’ exhaust pipes, and
thereby improve air quality. Previous emission control limits have been
met with various technologies focussed on the engine, but in order to
meet the latest requirements, manufacturers have added aftertreatment
devices in the exhaust system.
In order for these to work, engines must be fuelled with ultra low
sulphur diesel (15 parts per million of sulphur or less). More than this
and the aftertreatment systems will be overwhelmed with soot particles,
the backpressure on the engine will increase and it will quickly
overheat, perhaps causing permanent damage.
Manufacturers and their dealers can control where machines are sold
when they’re new, so there isn’t too much risk of an Interim Tier 4/Stage
IIIB machine initially finding its way into a country where the right
fuel is unavailable. However, the used equipment market is a global
one, and after a few years of work with their first owner in Europe or
the US, popular machines like excavators can find themselves anywhere
in the world.
Manufacturers say that they could potentially provide aftermarket kits
to ‘de-tier’ engines – essentially remove the aftertreatment components
that are sensitive to dirtier fuel. However, while this is technically
feasible, the legislative implications are far from clear.
Although developed world countries do not have emissions standards
as high as Interim Tier 4 and Stage IIIB, many do have emissions laws
of some kind. The legislative question is, if an engine is de-tiered,
would it then have to be re-certified to prove that it could meet a
different emissions law?
It’s a question that no-one seems to know the answer to at the
moment. That’s fine, as it’s not a pressing issuee right now – Interim

HIGHLIGHTS
GLOBAL
NEPAL The World Bank has approved
Global recovery
a US$ 63 million assistance package to
improve infrastructure and to construct
a power transmission line in Nepal. The
scheme includes a 132 kV transmission
line from Kabeli Bazaar, in the north of
Panchthar district, to Damak in Jhapa
district. Substations will also be built
near Kabeli Bazaar and at the towns of
Phidim, Ilam and Damak.
ITALY The Italian earthmoving
machinery market contracted by -14%
year-on-year during the first quarter of
the year, with 2236 units sold. Sales of
road building equipment and backhoe
loaders were the worst affected,
registering decreases of -42% and
-36% respectively, according to Italian
construction equipment association
Unacea.
CHINA The World Bank has approved
a US$ 300 million loan to support the
construction of a 19.5 km light rail line
in the city of Kunming, Yunnan province.
The new stretch of track will form Line
Three of the Kunming municipal highspeed rail transportation network plan,
which will eventually comprise six lines
covering 162 km.
KAZAKHSTAN The European Bank
for Reconstruction and Development
(EBRD) has announced up to US$ 100
million in funding to improve drinking
water and sewage infrastructure in the
Kazakh municipalities of Taraz, Atyrau
and Semey. The funds will be used as
seed money in preparation for public
private partnership (PPP) contracts.
CHILE Government investment agency
Proinversion has launched the prequalification stage for construction of
the new Chinchero airport. The scheme
is expected to cost at least US$ 350
million, and a short list of bidders will
be selected by early July.
VIETNAM The Asian Development
Bank (ADB) and State Bank of Vietnam
have agreed a package of loans
worth US$ 4.5 billion to improve
access to clean water, improve urban
infrastructure and conserve endangered
forests across Vietnam. In the country’s
largest cities 30% to 40% of treated
water is lost before it reaches the end
user and 40% of families have no
connection to a central water supply
system.
World construction output will return to growth
this year, but the residential sector looks sluggish.
lobal Construction output will grow +3.0% this year according to IHS
Global Insight, underlining the industry’s recovery. The economic
forecasting company said this compares to a decline of -0.1% last year.
In terms of individual sectors, non-residential construction will lead the
way with a +4.3% increase in activity, and among the most attractive subsector will be construction linked to the communications industry.
The infrastructure sector is also expected to have a good year, with +3.7%
growth forecast. Energy infrastructure is expected to see the strongest rise,
at +4.8% growth.
In contrast, the global residential construction market looks sluggish,
with IHS Global Insight expecting to see just a +1.2% rise in output this
year. According to the company it will take until 2015 for this segment
to regain the peak level of US$ 2.5 trillion seen in 2006. In contrast, the
overall construction market is expected to be back at the pre-crash high of
US$ 6.0 trillion next year.
Developing Asia and South America are expected to see the strongest
growth next year, some way ahead of other developing markets such as the
Middle East, Africa and Eastern Europe. Western Europe is expected to see
its construction market return to growth this year, although it will expand
by only a fraction of a percent, while North America will see another
decline, driven by continued weakness in the residential market.
It is this continued poor performance in the North American house
building sector that is slowing the overall global residential segment.

Enforcement
criticism
Anti-corruption
organisation
TI said there was little or no antiTransparency International (TI)
has criticised the Organisation
for Economic Co-operation and
Development (OECD) countries
for poor enforcement of their own
anti-bribery convention, which was
adopted in 2009.
A report by TI shows that out of
the 37 rich nations that make up
the OECD group, only seven have
active anti-bribery enforcement in
place - Denmark, Germany, Italy,
Norway, Switzerland, the UK and
US. However, this relatively small
group of countries represents 30%
of world trade according to TI.
“Only where there is active
enforcement is there sufficient
deterrence against foreign bribery.
The collective commitment to
stamp out foreign bribery made by
all OECD parties is undermined
when a large number of countries
have inadequate enforcement,” said
TI chair Hugette Labelle.
bribery enforcement in place in
Australia, Austria, Brazil, Bulgaria,
Canada, Chile, the Czech Republic,
Estonia, Greece, Hungary, Ireland,
Israel, Luxembourg, Mexico, New
Zealand, Poland, Portugal, the
Slovak Republic, Slovenia, South
Africa and Turkey.
TI is urging laggard governments
to put timetabled plans in place
to strengthen their enforcement
measures. It has also suggested that
a list of these countries should be
published by the OECD’s working
group on bribery, so private
companies will be aware they need
to take extra care and perform
additional due dilligence when
doing business in these areas.
According to TI, bribery can
account for as much as 25% of
government procurement costs.
The World Bank puts the cost of
corruption at US$ 1 trillion per
year.
US
Cut-backs
claim
jobs
Construction employment
fell
in 179 out of 337 (53%) of US
metropolitan areas in April,
compared to the position a year
ago, according to analysis by the
Associated General Contractors
of America (AGC). Employment
increased in 114 areas (34%) and
was static in 44 (13%).
The AGC said the fall in
employment was due to public
sector cutbacks. “At a time when
private sector construction activity
appears to be on the mend, local,
state and federal funding cuts
for infrastructure projects may
be forcing layoffs in many metro
areas,“ said AGC chief economist
Ken Simonson.
The largest job losses in absolute
terms were in New York City,
where 9800 jobs (-9%) were lost
in the year, followed by Las Vegas
(7500 jobs/-16%) and Atlanta
(7300 jobs/-8%). In percentage
terms, the biggest loser was the
Steubenville-Weirton area in Ohio,
where construction employment
fell -25%, equating to 500 jobs.
However, 7400 jobs were added
in Dallas, a +7% increase, and other
metro areas in Texas also performed
well. Forth Worth added 2900 jobs
– +5% – and the Beaumont-Port
Arthur area added 2300, or +13%.
According to the AGC, the US
private non-residential market is
stabilising, and in the residential
sector, multi-family projects are on
the up, but these are being offset by
falls in public construction.

Ambitious
target
The National Highways Authority
of India (NHAI) has set a target to
award construction contracts for
7300 km of roads in the April 2011
- 2012 financial year. It says it will
put some 10000 km out to tender
to help ensure the award target is
met.
Last year the NHAI awarded a
record 5083 km of work, so this
target represents a +44% increase
in activity.
The NHAI has also produced
more detailed monthly targets of
what it hopes to achieve, and these
detail some 59 individual schemes,
with a total length of 7994 km and
a total value of INR 56939 crores
(US$ 12.7 billion).
According to these monthly
targets, the busiest period for
awards will be the summer
months, with the July to
November period expected to see
41 schemes awarded, totalling
5832 km and worth some
INR 34754 crore (US$ 7.8 billion).
The NHAI is also looking towards
the private sector to fund these
schemes by way of concession
agreements. It says about 75% of
the work it expects to award in the
current financial year is suitable
for build-operate-transfer (BOT)
agreements.
The remaining 2000 km is either
viewed as not financially viable for
BOT, or is the responsibility of
state governments, and is therefore
outside of the NHAI’s direct
control.
CHINA Construction has started on the Foster + Partners’-designed
headquarters tower for CITIC Bank in Hangzhou, China. The striking 100 m
high tower will feature a 30 m high, 72 m wide canopy at its base, and a
central atrium rising up through the all 20 of the building’s storeys. Upper
levels will feature gardens and a VIP club in addition to meeting rooms.
The tower will be naturally ventilated for part of the year, and will feature
water recycling systems. Local construction materials will be used where
possible.

Construction output in the
industry
contracted just -0.6% last year,
following 2009’s -13.2% fall,
thanks to increased residential
work. A return to growth is
expected this year.
Economic forecaster PMR said
the wildfires that ravaged parts of
Russia in the summer of 2010 had
fuelled demand for housing, and
2200 new homes had been built
over two-month period in 2010
for the victims of the disaster. In
addition to housing, more than
200 km of roads and 100 km of gas
pipelines were also needed.
The construction sector also
received a boost from the decision
to award the 2018 FIFA World
Cup to Russia, which will require
stadiums, airports, road and rail
connections to be either built or
modernised in the coming years.
In addition, PMR said civil
engineering projects related to
the 2012 Asia-Pacific Economic
Cooperation (APEC) Summit in
Vladivostok and the 2014 Winter
Olympics in Sochi have also been
major drivers of construction
activity, with many of these projects
now nearing completion.
27-country
European
Union
(EU27) increased +1.9% in March
compared to the previous month.
However, figures from Eurostat,
the statistical office of the European
Union, show output was still -4.9%
lower than a year ago.
The highest month-on-month
increases were seen in the UK
(+15.8%), Germany (+6.2%) and
Slovakia (+5.6%), and the largest
decreases in Slovenia (-7.4%),
Portugal (-5.1%) and Bulgaria
(-3.1%).
Across the EU27, building
construction was up +1.0%, while
civil engineering rose +2.1% in
March compared to February.
In terms of the annual change in
output, the biggest rises were seen
in Poland (+23.5%), Germany
(+16.2%) and Sweden (+6.2%),
while the biggest falls were in Spain
(-38.0%), Slovenia (-30.8%) and
Bulgaria (-19.1%).
The annual comparison showed
building
construction
across
the EU27 was -6.5% lower in
March than a year ago, while civil
engineering was up +3.9%. Civil
engineering was the only segment
where growth in the 17 country
Euro-area beat that of the EU27.

The World Bank has approved a
grow by +11% this year, although
growth there is predicted to be
slowdown over 2012 and 2013,
according to a report by research
company PMR.
Growth this year will be driven
by large civil engineering projects,
some of which are linked to
the 2012 European Football
Championship.
In a survey of the 200 largest
construction companies, road
construction was named by 59% of
respondents as the most attractive
sector of the industry over the next
two years. This strong response was
expected, but was much lower than
March 2011 (76%) and September
2010 (81%).
Capital expenditure on water
supply and sewage infrastructure,
and on railway construction
projects will also drive growth.
CHINA
High-speed
stop
The Chinese government
has
ordered a halt to construction work
on the Tianjin to Qinhuangdao
high-speed rail link due to the failure
to comply with environmental
inspections.
The order follows the closing
of a completed line between
Qingdao and Jinan due to its lack
of environmental evaluation and
approval.
These cessation orders have been
interpreted by some as a signal
that the government plans to scaleback its ambitious high-speed rail
construction project. From just
1500 km of high-speed track at the
end of 2008, the government has
previously said it wanted to have
13000 km complete by the end of
next year.
A further blow to the project
was the dismissal of Liu Zhijun,
the secretary general of China’s
Ministry of Railways in February,
on suspicion that he had taken
more than US$ 100 million in
bribes and kick-backs.
Average value is US$ 35.1 million. Resolution
takes more than 9 months.
onsultant EC Harris said it saw a rise in the global number of
construction disputes around the world in 2010, compared to 2009.
Data from the company’s Contract Solutions division showed that
the average value of disputes it handled was US$ 35.1 million, and disputes
took more than nine months on average to resolve.
EC Harris said the biggest cause of disputes was a failure to properly
administer contracts. This was followed by ambiguities in the contract
document, failures to make interim awards on time extensions and
monetary relief, unrealistic risk transfer from clients to contractors and
changes imposed by the client or employer.
Disputes took the longest to resolve in Asia, with an average length of
11.4 months. This was followed by Europe (10 months), North America
(9 months) and the Middle East (8.25 months). As well as being the longest
to resolve, Asian disputes were the highest value, at an average of US$ 64.5
million. The region was followed by the Middle East (US$ 56.3 million),
Europe (US$ 33.3 million) and North America (US$ 17.5 million). The
largest dispute EC Harris handled in 2010 was worth US$ 200 million,
and this was in Asia.
Joint ventures were also cited as a source of difficulty. EC Harris found
that where a joint venture was in place, differences within the joint venture
were likely to drive a dispute on 31% of occasions. This phenomenon was
particularly marked in the Middle East, where joint venture-related issues
led to disputes in 50% of occasions.
C
ALBANIA Bjarke Ingels Group (BIG), Martha Schwartz Landscape, Buro
Happold, Speirs & Major, Lutzenberger & Lutzenberger, and Global Cultural
Asset Management have won the competition to design a new 27000 m2
Islamic cultural complex in Tirana, Albania.
The centre’s mosque will be able to accommodate up to 1000 people
performing their daily prayers, with courtyards and public spaces, taking
this up to 5000 on Fridays and up to 10000 on special holy days.
The facade takes its inspiration from Islamic mashrabiya screens, which
provide shading and privacy while still allowing views out. The light qualities
of the mosque will change throughout the day as the light washes across
the curved facades.
The design also includes The Quran Gardens containing all of the plants
mentioned in the Quran in the same amount as the number of times they
appear in the Islamic holy scriptures.
US$ 640 million loan towards the
US$ 800 million Upper Cisokan
Pumped Storage Hydropower
project near Bandung in West
Java, Indonesia. The project will
be run by Indonesian state-owned
electricity company PLN.
The scheme is designed to help
meet peak electricity demand by
transferring water from an upper
to a lower reservoir via a set of
turbines. The water is pumped back
to the higher reservoir at off-peak
times. The facility will have a 1 GW
generation capacity.
World Bank senior energy
specialist Leiping Wang said,
“Pumped storage is the only form
of technology that allows you to
efficiently store large amounts
of energy and quickly respond
to peak electrical demand. The
Upper Cisokan project will
make Indonesia one of very few
developing countries to have such
a power plant.”
In a separate development, the
World Bank has also announced
a US$ 250 million loan for the
Western Indonesia National Roads
Improvement Project. The project,
which is managed by the Indonesian
Ministry of Public Works, aims to
improve approximately 716 km of
national roads in Western Sumatra.
CHILE
New metro

Construction of Lines 3 and 6 of

is due to begin next year. President
Sebastián Piñera announced the
projects in his annual state of the
union address.
The projects comprise 37 km of
track and will connect five districts
to the metro network. Line 3 will
run through the centre of Santiago,
linking northern and southern
areas, and has an estimated cost
of US$ 400 million. Line 6 will
connect the districts of Cerrillos
and Vitacura. The metro will also
feature free Wi-Fi Internet access.

The assets being sold include cement plants in Harleyville, South Carolina
and Roberta, Alabama along with a cement grinding plant in Atlanta,
Georgia and associated cement terminals. Lafarge is also selling its readymixed concrete businesses in these areas of the US. Last year these businesses
had revenues of US$ 240 million.
Following the divestments, Lafarge will still have 21 cement and grinding
plants in the US with a total capacity of some 19 million tonnes. Lafarge
chairman & CEO Bruno Lafont said, “North America is an essential pillar
for the group, where we have the ambition to be the undisputed leader
in the building materials industry. This transaction creates value for our
shareholders while maintaining a strong network of operations for future
growth in North America.”

ECONOMIC OUTLOOK
Return of the tigers
Investment in residential, non-residential and infrastructure projects, combined with reconstruction
work in Japan will cement the Asia-Pacific region’s place as the fastest growing construction
market in the world. Scott Hazelton reports.
the biggest story is in Japan, where earthquake
reconstruction will turn the world’s third largest
construction market from the region’s laggard
into one of the growth leaders. The immediate
aftermath of the natural disaster and electricity
shortages of course caused economic difficulties,
and the Japanese economy will probably contract
at about a -5% to -6% in the second quarter of
the year, after a small drop in the first quarter.
However, assuming that reconstruction efforts
get under way in the summer, the annualised
GDP growth rate in the second half of 2011
could be +7% to +8%, before gradually settling
to the pre-earthquake baseline of +1.5% to +2%.
Uncertainty remains around the extent and
duration of the power generation shortfall as the
impact of even limited electricity disruptions for
some industries and their global supply chains
could be very large.
Reduced activity in the first half of the year
with a focus on rescue and recovery implies that
even robust building in the second half of the
year will hold overall construction growth in the
+3% range. However, growth is forecast to rocket
to +8% in 2012 and another +4% in 2013 as the
bulk of rebuilding occurs in these two years.
China turned in another impressive year in
sian economies are poised for further
growth in 2011, following a better than
expected year in 2010. Asia as a whole
experienced a near-record expansion in 2010,
with growth of +7.0% and IHS Global Insight
expects a further +5.4% increase in economic
activity this year, driven by investment, and to a
lesser extent, private consumption.
Much of the fiscal stimulus in Asia during
the global recession targeted infrastructure
development, and residual effects from these
projects will continue to support the construction
sector in 2011. But there is still a tremendous
need for infrastructure upgrades and expansion
in many countries in Southeast Asia. With
capital markets in much better shape, financing
such plans will become easier.
The key concern is that there may be capacity
constraints in certain countries and industries,
following sharp rises in utilisation rates last year.
Although this could be a brake on growth, the
need to invest in more capacity will be a plus for
the construction industry.

2010, and contrary to expectations, shows no
sign of abating in 2011. Indeed, it now appears
that growth could even accelerate slightly, and
2012 and 2013 also look very strong, although
growth will slow.
While the residential market, and to some
extent the commercial market, attract attention
due to concerns over an asset pricing bubble,
this remains a concern mostly within the larger
metropolitan areas and at the higher end of the
pricing spectrum. Most residential construction
in the forecast arises from affordable housing
as the government continues to encourage
migration from rural areas to cities, although
they are the second tier interior cities, rather than
those in the coastal region.
Infrastructure spending remains more
significant in China. Urbanisation will drive
transportation, water and sewage infrastructure,
while the next Five Year Plan aims to connect
lesser developed provinces and other areas, such
as Tibet, into the broad national economy. This
requires massive investments in road, rail and
power infrastructure.
Foreign investment
India’s construction market outperformed China
in 2010 in terms of growth, although in absolute
terms it is only a fraction of the size of the Chinese
market. Growth will continue thanks to heavy
investment in power and transportation projects,
and India is also seeing strong investment in the
private sector. While the government deficit is
large, foreign direct investment is pouring in to
the country and financing projects is not proving
to be a problem, even with credit markets
remaining tight.
Indonesia and Vietnam are the other fast
growing construction markets in Asia, although
growth in Indonesia is expected to slow, while
Vietnam will see an acceleration. However,
Vietnam has yet to develop the national
consensus of India and China in long term
planning, so while growth is strong, the market
remains small and the projects fragmented.
Australia has been plagued by natural disasters
in recent months that will hold back growth in
2011, even with strong commodity prices that
tend to boost this economy. As the country
recovers from such impediments as flooding in
its coal region, and commodity prices remain

elevated with global economic recovery, the need
to get more materials into production will lead to
a construction rebound.
Infrastructure spending will dominate growth
potential through 2012 for the region, partly due
to the outsized influence of China. In the near
term, this is a reflection of the lingering effects
of stimulus spending, but the effect of planned
national development schemes are growing, and
will be a future driver.
Residential construction activity will improve
across the region with time. In the case of
Australia, and to some extent South Korea, this
represents a cyclical recovery from what is likely
to be a down year in 2011. In Japan meanwhile,
there will be an acceleration in the residential
market due to post-earthquake rebuilding.

Nonresidential Structures
Non-residential structures will see a broad
recovery in most markets. Japan will need to
rebuild or substantially repair hundreds of
manufacturing facilities, as well as institutional
structures. In the export-led markets of the
region, economic improvement in the U.S. and
Europe will improve industrial production once
again and require expansion, although concerns
of overcapacity in some manufacturing sectors is
justified.
Indeed, China will pull back investment in
some inefficient industries to focus on newer,
higher value sectors such as pharmaceuticals.
Growth in commercial structures (office, retail,
hotels) will also help as the region’s economies

endeavour to move away from dependence
on exports, and increasetheir own domestic
consumption.
Resilience
Asia is increasingly proving fears of a pronounced
slowdown to be unfounded.
While concerns over asset bubbles and access
to financing remain, the region is proving quite
resilient. Reconstruction in Japan will only
add fuel to what is the world’s fastest growing
construction market. But while growth will
have to slow in the medium to long term, the
risks to the forecast seem to be transitioning to
opportunity.

REGIONAL REPORT: ASIA PACIFIC
Bouncing back
Bouncing back
The Asia Pacific region has rebounded from the
global recession and is set to consolidate these gains
in the coming years with increased investment in
infrastructure. Helen Wright reports
any of the economies in the Asia Pacific saw GDP
surge back to growth in 2010 after being hit hard by
the global recession in 2009. The region’s construction
sector also has momentum and looks set to benefit from
increased investments in infrastructure and housing projects in
2011 and beyond.
Central to growth in the region as a whole are the financial
hubs of Singapore and Hong Kong, which are amplifying
interregional relationships and are themselves increasingly
dependent on the successes of Asian partners as trading expands.
Singapore’s construction sector has benefited from increasing
private sector investment. Last year alone, construction contracts
awarded to private-sector companies doubled in value to
US$ 14 billion as house prices rose and demand for commercial
and industrial buildings increased in line with the economic
recovery.
This high private sector investment came despite the fact that
growth in the construction sector as a whole slowed to 6.1% in
2010 from 17% in 2009 – a decline that the Asian Development
Bank (ADB) said was down to the fact that some major public
projects were completed in the last two years.
M
17 Liebherr Crawler cranes and an LR1280 lattice boom
crawler are being used on Hong Kong’s Central Reclamation
Phase 3 Project – constructing more than 2600 m of 1.20 m
thick diaphragm walls and barrettes (special, bored piles)
over a distance of 900 m.
Similarly, large-scale projects are also having an impact on
Hong Kong’s construction sector. Major public infrastructure
projects begun in the past two years, including the Guangzhou–
Shenzhen–Hong Kong express rail link and the Hong Kong–
Zhuhai–Macao Bridge, will continue contributing to growth in
the coming two years.
Indeed, Hong Kong’s 2011 budget has increased by nearly
+25%, with spending on capital works to hit US$ 7.5 billion
this year.
And construction opportunities also abound in some of the
smaller economies in the Asia Pacific region. In Vietnam, for
example, strong public infrastructure investment pushed overall
construction growth up by +10.1% last year.
Loans from the ADB and other development organisations are
also helping to drive infrastructure projects forward in Vietnam.
In March, for example, the ADB loaned the Vietnamese
government US$ 293 million to support a US$ 1 billion
metro rail project in the capital, Ha Noi, while the ADB is also
providing US$ 1 billion towards a US$ 2.8 billion programme
in provide piped water to 3 million households.
Natural resources
Other smaller economies in the region are exploring the
development of their lucrative natural resources. Papua New
Guinea is a case in point, where the start of a US$ 15 billion
liquefied natural gas (LNG) project last year has heralded a
surge in imports of construction equipment and helped offset
a -4.1% decrease in government expenditure in 2010 (see box
story for full details).
Meanwhile construction activity rose by +10.5% in the
Philippines in 2010, driven by strong demand for new
buildings from the business process outsourcing subsector.
And while the 2011 budget reduces infrastructure spending,
the sector is expected to stay buoyant due to interest from the
private sector.
Five initial infrastructure projects, including construction of

LNG in Papua New Guinea
Volvo machines put to work on US$ 15 billion development
US$ 15 billion project to develop the untapped gas and liquid hydrocarbon resources
in the southern highlands and western provinces of Papua New Guinea is boosting
the country’s economy.
The 15-year Papua New Guinea Liquid Natural Gas project (PNG LNG) began last year and
involves the construction of an LNG plant, an airport, offshore and onshore pipelines and
transport to the areas via an airport and several roads.
Volvo has supplied 125 machines for use on the PNG LNG including articulated haulers,
crawler excavators, wheeled loaders and motor graders. The company said the deal
represented a “major breakthrough” for its construction equipment unit in the oil and gas
sector.
The ADB estimated that the construction of the plant will boost Papua New Guinea’s GDP
growth up to 8.5% in 2011, from 7.1% in 2010, but the figure is forecast to ease to around
6.5% in 2012 when construction starts to taper off. The first LNG deliveries are scheduled to
begin in 2014.
A
expressways and the privatisation of light railway operations in
Manila, are to be put out to tender by mid-year under public–
private partnership (PPP) arrangements.
Assuming that good progress is made
starting such projects, the ADB forecasts
that GDP in the Philippines will grow
+5% in 2011 and +5.3% in 2012.
In Thailand, 2010’s GDP growth of
+7.8% would have been much harder
to achieve without heavy government
spending under the country’s THB 1.4
trillion (US$ 46.7 billion) three-year
Thai Khem Khaeng (make Thailand
strong) stimulus programme.
Introduced in 2009 to support
Thailand’s recovery amid the global
recession, spending under the programme
contributed 2.3 percentage points to
GDP expansion in 2010.
Funds are being allocated to a number
of infrastructure projects including
expanding highways, housing projects,
improvements to the water network and
high-speed train system linking Bangkok and Rayong.
Thailand has strong trade ties with Indonesia, where the
government has budgeted for a +30% rise in capital expenditure
in 2011 aimed at addressing infrastructure bottlenecks – a
persistent problem that contributed to the country’s 7%
inflation in December 2010.
However, the ADB described Indonesia as suffering from a
“chronic weakness” in implementing capital works programs,
meaning that the budgeted amount is unlikely to be fully
drawn. To address this issue, the government is simplifying
budget execution procedures and strengthening procurement
capacity in the spending agencies.
Malaysia, meanwhile, has made good progress with
infrastructure projects and has also seen construction activity rise
on the back of increased demand for residential buildings and
expansion in office space.Last year, the country’s construction
sector grew by +5.2%, while GDP rebounded to +7.2% in
2010, from a contraction of -1.7%
in 2009.
The economies of the Asia Pacific
region have proved resilient in the face
of the global financial crisis and spending
on infrastructure is a firm fixture of both
public and private budgets in the coming
years. While the full impact of the
disaster in Japan (see box story) must be
monitored closely, it is also likely to have
a positive impact on construction activity
in terms of the effort to rebuild.

How the disaster will affect 2011 GDP
growth is hard to quantify since it is still
unfolding, but according to the Asian
Development Bank, the affected region
accounts for around 6% of Japan’s GDP
and the role of Japanese companies in
global manufacturing networks means that
some supply-chain disruptions have already
occurred.
The ADB said estimates of the total cost
of the damage range between US$ 150
billion and US$ 200b billion – representing
between 3% and 4% of Japan’s GDP.
This huge cost comes at a time when
Japan’s net public debt is over 120% of
GDP, and while the construction sector will
be boosted by the rebuilding efforts, the
cost could restrain future economic growth
in Japan in the medium term.

The global excavator
market split decisively
in two this year due to
demanding engine exhaust
emissions regulations
coming into force in Europe
and the US. Chris Sleight
reports on what this means
for equipment users and
the flood of new models
being launched.

to target markets outs Europe and the US. The
machines were launched at Bauma China.

EXCAVATORS
Different worlds
isitors to construction equipment exhibitions like Samoter,
Smopyc and ConExpo earlier this year would have seen
the first in a new range of excavators from many of the
sector’s leading players. These have been launched in response to
the new US Interim Tier 4 regulations on exhaust emissions, and
the equivalent European legislation, Stage IIIB.
The key change from the previous laws (Tier 3/Stage IIIA)
is that manufacturers have had to make a massive cut in the
amount of particulate matter (PM) emissions – the visible black
soot that comes out of a machine’s exhaust pipe. To achieve
this, manufacturers have added to emissions reductions systems
they already had in place, with aftertreatment modules into the
exhaust system – devices like diesel particulate filters (DPFs) that
physically trap and burn-off the soot.
But the on-board technology is only part of the story. In order
to work properly, engines must be fuelled with ultra low sulphur
diesel (ULSD), which means around 15 parts per million (ppm)
of sulphur or less. The amount of PM formed is directly linked
to the fuel’s sulphur content, and if anything other than USLD is
used in a Stage IIIB/ Interim Tier 4 engine, it will clog the filter,
leading to an increase in backpressure on the engine and causing
it to break down.
Unfortunately, ULSD is not widely available for off-highway
vehicles outside the US and Europe, and this means that, even if
they wanted to use low emission machines, contractors and rental
companies outside these regions would be ill-advised to buy an
Interim Tier 4/Stage IIIB excavator.
At the moment, the legislation only
affects larger machines. The first wave
of laws that came into force at the
start of the year applied to 130 kW to
560 kW engines, which translates to

Komatsu’s first Interim Tier 4 /Stage IIIB
machines include the 24 tonne class

excavators from about 25 to 100 tonnes
operating weight. However, subsequent
introductions over the next two years will
see engines as small as 37 kW affected,
which will cover anything larger than
about a 5 tonne mini excavator.
Two markets
One of the effects of these laws is that they
have divided the global excavator market
in two, with highly regulated markets like Europe, Japan and
the US requiring machines with low emission engines, and the
rest of the world requiring less exacting technology. In fact some
manufacturers say there are three markets – the highly regulated
countries, the lesser regulated countries (including China) and
the countries with no emission laws at all.
A question that no-one is prepared to answer at the moment
is what happens to Interim Tier 4/Stage IIIB machines when
they are sold by their original owners after a few years. The used
equipment market is an international one, particularly when it
comes to popular machines like excavators. So will it affect a
machine’s residual value if it cannot be sold from Europe, Japan
or the US to a less regulated country, because it will break down
due to poorer fuel?
Some manufacturers say they have a technical solution to ‘detier’ engines and remove these sensitive aftertreatment systems,
but that it is not clear how this would fit in with legislation
around the world. For example, if an engine were de-tiered for a
lesser regulated market, would it then have to go through a costly

re-certification procedure to prove it met the standards in this
new country?
Chris Rees, president of European operations at Volvo
Construction Equipment said, “We have a technical solution,
because we realise Stage IIIB machines could be sold outside
Europe. Now we need a legislative solution to find agreement with
European authorities and the EPA [Environmental Protection
Agency] in the US to de-tier machines. It’s a work in progress.”
With Stage IIIB/Interim Tier 4 machines only just coming
onto the market, this problem is a few years away. However, it
is something to consider for buyers in Europe, Japan and the US
if they have traditionally sold their used excavators outside those
regions.
But in terms of new machines,
manufacturers have been forced into the
position of building at least two different
models of each machine for different
markets around the world. According to
Off-Highway Research, 195375 crawler
excavators were sold in the major markets
of China, Europe, India, Japan and the
US last year – 75% of them in China.
Doosan’s first Stage IIIB/Interim
Tier 4 compliant excavator is the 30
tonne class DX300, which was on
display at ConExpo.
Saudi workhorses
Hitachi machines prepare the ground for Riyadh financial centre
fleet of seven new Hitachi Zaxis excavators, along with three new ZW wheel
loaders is involved in the construction of the King Abdullah Finance Centre in
Riyadh, Saudi Arabia. Among the machines are two 35 tonne ZX350H-3s and three
25 tonne ZX250s, bought especially for the round-the-clock project by M/s. Afkar Najd
Contracting Co.
The development started in July 2010 and will see the creation of a 1.5 million m2
financial district, incorporating business premises, a grand mosque and Saudi Arabia’s new
stock exchange centre including a financial training institute: The King Abdullah Financial
Academy. Construction is expected to take five years.
M/s Afkar Najd Contracting Co was established in 2005 and owns more than 100
machines. The company’s General Manager, Mr Naji Al-Haidry, said, “The King Abdullah
Finance Centre will be the East’s first financial district to match up to the major global
financial centres, so it is very important that we do a first-class job.
“We purchased ten Hitachi machines, both excavators and wheel loaders, because they
have an excellent reputation for reliability, fuel-efficiency and productivity, all of which
were important elements for a project of this scale.”
A
Case’s new C series excavators offer
faster cycle times and better fuel
efficiency than their predecessors.
What’s more, with 11450 excavators
sold in India, this market edged ahead of
the US as the world’s third biggest market,
and looks poised to take the no. 2 spot
from Japan over the next year or two.
Brazilian trade association Sobratema
meanwhile said some 5500 excavators
were sold in the country last year, making
it probably the world’s fifth largest
excavator market, below the US, but well
ahead of Germany.
This all goes to show the importance of the various developing
markets around the world. It also explains why manufacturers are
putting in such effort to target these countries with machines that
are designed for their specific needs.
One of the more interesting approaches is from Volvo.
The Swedish manufacturer has a majority stake in Chinese
manufacturer Lingong, which produces excavators and other
machines under the SDLG brand.
Speaking at last year’s Bauma China exhibition, the thenpresident & CEO of Volvo Construction Equipment, Olof
Persson, said the company will use machines manufactured by
Lingong to appeal to what it describes as the “mass market”.
“We have set a strategic target to be number one, two or three
in the BRIC [Brazil, Russia, India, China] countries. If you look
at revenues, the BRIC countries account for about half of what
we achieved this year.”
“Volvo is a premium international brand and SDLG is a strong
Chinese brand for the mass customer market. This is not a
contradiction. It is a logical way to address a very large market
with different customer needs. The dual brand gives us a unique
opportunity,” said Mr Persson.
New machines
But despite the importance of emerging markets, most major
manufacturers are putting a strong emphasis on the new Stage
IIIB/Interim Tier 4 machines they need to introduce in the US
and Europe to stay in the game. These were certainly the major
launches at the various industry exhibitions in these territories in
the first quarter of the year.
Caterpillar has been perhaps the most ambitious in its new
launches, with its stand at the ConExpo featuring six new
tracked excavators. Caterpillar hydraulic excavator product and
application specialist Kent Pellegrini described it as, “One of the
most comprehensive excavator launches for Europe and North
America in Caterpillar history.”

Different worlds
The new equipment on display included a pre-production
version of the 16 tonne class 316E, the 20 tonne 320E, the 36
tonne 336E, the 50 tonne class 349E, the 74 tonne 374D and the
90 tonne 390E, which will replace the 385D.
The new, more efficient Stage IIIB/Interim Tier 4 engines have
been combined with higher pressure hydraulics and a regeneration
valve on the boom hydraulics to increase both performance and
fuel efficiency. The 336E for example is said to burn -6% less fuel
than its predecessor.

The latest addition to Hidromek’s
excavator range is the 14 tonne class
140W wheeled machine, shown here at
its launch at the Samoter exhibition.
Sumitomo’s US subsidiary, LBX, markets excavators under
the Link-Belt brand. The latest Interim Tier 4 machines are
the X3 series.
Congestion buster
JCB 36 tonner put to work on 60 km Italian highway
onstruction of the 60 km ‘Bre.Be.Mi’ six-lane highway connecting Milan, Bergamo
and Brescia in northern Italy is a key part in the country’s road modernisation
scheme. Due for completion in 2013, it is expected to save frustrated motorists some
6.8 million traffic hours per year.
The project has been split into several different working zones and in one of them, in the
Chiari area, near Brescia, there are currently around 10 JCB machines working, including
JCB excavators which are involved in the
initial earthmoving contract needed to turn
the project into reality.
Among the machines is a JCB JS360 NLC
tracked excavator which is being used to
help dig the miles of trenches needed for
the project. Working alongside it are JS290
tracked excavators and JCB 8045 and 8052
midi excavators.
Weighing in at 36.5 tonnes, the JS360
features AMS (Advanced Management
System), a computerised system which
offers precision control, giving access
to four working modes at the touch of a
button. The AMS raises productivity and
cuts operating cost by matching engine and
hydraulic output to demand.

50 tonne classes. Features include an
automatic idling system that cuts engine
revs to save fuel and reduce noise when
the machine’s controls aren’t being used.
There are also five different work modes –
idle, fine, heavy, general and power-max –
and the ability to customise the machines’
performance for up to 18 different
attachments.
Volvo describes both the undercarriage
and booms on the machines as “heavy
duty”, and there is also a boom float
option, which lowers the boom by gravity,
freeing up hydraulic flow for other functions.
Komatsu meanwhile used ConExpo to take the wraps off the
PC240LC-10, a 25 tonne machine, and the company’s first
Interim Tier 4/Stage IIIB machine. Operators will notice the new
high resolution 7 in (178 mm) display, which is used to select
one of five working modes, as well as provide information on
operating parameters. The monitor can also display features from
the rear-view camera, which is a standard piece of equipment.
Komatsu also highlights the machine’s new load sensing
hydraulic system, which it says has taken hydraulic efficiency to
a new level. This is based on a new system called variable speed
matching, which adjusts the engine speed
based on the loads from the hydraulic
system. Komatsu says that this, combined
with other improvements, reduces losses
in the hydraulic system, makes for better
efficiency and lowers fuel consumption.
Case’s first Stage IIIB/Interim Tier
4 excavator offering comprises four
machines, the CX250C, CX300C,
CX350C and CX370C, which cover
the 25 to 37 tonne weight classes. Case
says the new engines make the C series
machines as much as +10% more fuel

energy saving features, including an engine idle function, which
cuts revs when the boom is not in use. However, Case has also
increased performance, with the C series offering +5% faster cycle
times than the previous generation and about +7% more lifting
capacity, depending on the model.
A new cab, +5% larger than on the B-series is a feature many
operators will appreciate, as is the new 7’’ (178 mm) in-cab LCD
display.
Case’s excavator partner is Sumitomo, based in Japan. In the
US Sumitomo excavators are sold under the Link-Belt brand, and
unsurprisingly, similar enhancements to Case’s are apparent in
the company’s new X3 series of excavators.

Quarry replacement
New 50 tonne Doosan is more powerful and cheaper to run
he latest addition to the Banner Contracts’ fleet operating at Lafarge’s Thrislington
limestone quarry at Ferryhill, UK is a new Doosan DX520LC crawler excavator, which
has replaced a Doosan S470LC.
Banner Contracts Company Director, Jo Banner, explained that while the S470LC had put
in some sterling work, the new DX520LC met a need for an excavator which could provide
greater output. “Our output of crushed rock is governed largely by the rate the crushers can
handle it,” he explained. “It is essential our prime mover, the new DX520LC, has the ability to
ensure the crushers are always working to full capacity.”
Although still a relatively new machine, Mr Banner said fuel records already showed a good
fuel saving. “The excavator works a 10 hour shift for five days a week which equates to a
saving of 100 litres of fuel a week or over 5000 litres for the year,” he said, “which is an
important saving for us.”
In addition to its performance and fuel savings, an important reason why the DX520LC
was purchased by Banner Contracts was its 10.75 m reach and 9.6 m digging height, which
enables it to reach and dress the edges of the shot blasted areas.
“The quarry geotechnical assessment, which requires a machine with the reach to scale
faces safely, makes the DX520LC a good choice,” explained Mr Banner. “It’s an important
issue and we are pleased to have a machine that performs so well in this area.”
A total of 1.2 million tonnes of crushed magnesium limestone is extracted from the quarry
each year, about half of which is processed in kilns to create dolime and the remainder is
used as fill and aggregates.

same improvements in operator comfort, performance and fuel
efficiency as Case’s machines. Link-Belt says it will also be adding
a 47 tonne class model this year as well as a variant of the 250 X3
with a longer boom and stick package.
Parent company Sumitomo meanwhile is investing in its
Chinese excavator plant. This year will see its factory in Tangshan,
Hebei province increase in capacity from 3000 units per year to
5000, and a 36 tonne machine will be added to the company’s
current 20 and 24 tonne excavator offering in China.
Meanwhile, Case’s sister company within the CNH group, New
Holland, has unveiled the first of two Stage IIIB/Interim Tier
4 excavators in its C series. Unlike most other excavators, new
Holland is using a Selective Catalytic Reduction (SCR) system
to reduce emissions.
This relies on a high combustion temperature in the engine
to limit the formation of PM, and the SCR handles the high
levels of nitrous oxide (NOx) – the other main pollutant covered
by emissions legislation – that is created as a result of this hot
combustion.

EXCAVATORS
Different worlds
Among the Latest additions to Liebherr’s excavator range
is the 23.7 to 26.4 tonne R916 excavator, which features a
115 kW engine.
The downside to this technology is that it works by injecting
a stream of urea into the exhaust gasses, which means another
fluid for excavator operators to monitor and keep topped-up.
However, many manufacturers will have to move to this system
to meet the forthcoming Stage IV/Tier 4 final legislation, so it is
something the industry will have to get used to.
New Holland’s new machines are the 27.9 tonne E265C and
31.6 tonne E305C. The company says a complete re-design of the
hydraulic system, encompassing the main pumps, spool, solenoid
and return valves, has significantly increased the machines’
controllability and hydraulic efficiency.
The cab meanwhile features a new colour monitor and more
responsive joysticks than on the previous model. The vibration
experienced by the operator has also been reduced thanks to new
dampers. These machines are marketed under the Kobelco brand
in the US.
John Deere’s first Interim Tier 4 excavators are the 250G, 290G
and 350G, spanning the 25 to 35 tonne weight classes.
“We’ve increased power and hydraulic flow while also adding
the IT4 engine,” said Mark Wall, John Deere’s excavator product
marketing manager. “The end result is +8% more productivity
for our customers.”
The new G-Series also retains a number of key features from the
previous D-Series, such as the Powerwise III management system
that balances engine and hydraulic performance.
The next models to be launched in the range will be the larger
470G, 670G and 870G, from 47 to 87 tonnes.
Hyundai’s allnew 9-series
excavator range
includes several
short radius
machines.
Pictured is the
23 tonne class
R235LCR-9, the
largest reduced
radius machine in
the range.
More to come
Like John Deere, all of the manufacturers in the excavator sector
will be rolling out additional models over the coming months
to meet the new emissions laws in Europe and the US. As these
machines come out, it will be crucial that manufacturers and law
makers find a way of addressing the issues that will arise if these
excavators are sold as used equipment to regions where ULSD
is not available. Once used Stage IIIB/Interim Tier 4 excavators
start going up for sale, there are going to be plenty of buyers in
developing countries that will need to ‘de-tier’ them.

Underground
successes
The largest, the longest and the deepest records have
again been broken in the tunnelling sector. Despite global
economic troubles, it is one part of the construction
industry that looks in good health in most parts of the
world. Adrian Greeman reports.
op of the tunnels list is the world’s longest transport
tunnel, the 57 km long twin bore, high speed railway
tunnel underneath the Gotthard Pass in Switzerland’s high
Alps. A significant milestone was achieved last year when one of
the Herrenknecht Tunnel Boring Machines (TBMs) driving the
eastern tube of the 8.5 m diameter bores broke through to set a
new world record for the longest tunnel.
Ten years of excavation, half by drill and blast and half by
TBM, under mountain cover of up to 2500 m, had involved
work with incredible rock pressures and high rock temperatures
up to 50° C.
Full completion of the total 152 km of tunnels and side caverns
was achieved in March when another Herrenknecht ended the
second western tube. Lining work continues and railway and
signal installation will follow before the first high speed trains
run in 2016.
T
An enormous 650 m work train, christened the “Worm” is being
used for re-profiling some of the tunnel, cleaning it, installing
drains and forming the linings. It is supplied by Herrenknecht
subsidiary Maschinen und Stahlbau Dresden (MSD).
Gotthard is not the only tunnel on the high-speed link. Work
has also begun on the 15.4 km long Ceneri twin bore tunnel
further south in Italian speaking Switzerland, passing under the
1100 m Monte Ceneri near Locarno.
The drill and blast drives are using primarily Sandvik 1300
three-boom rigs and with a long ceiling suspended back-up train
system from Rowa. Two drives each north and south are heading
out from a central cavern accessed by a side adit driven two years
ago by a Robbins main beam TBM at Sigorino. Breakthrough is
due in 2016.

deep under the mountains for heavy freight trains and superfast
250 km/hour passenger trains.
The 55 km long twin bore tunnel will almost match the
Gotthard and, if a link into an existing bypass tunnel at the
Tyrolean capital of Innsbruck is taken into account, will exceed
it. Pan-European trains heading for Berlin, Germany in 2025
from Italy will connect straight into the bypass giving a total
underground length of 62.7 km.
Italy committed funds last year and Austria this year for work
on the twin main drives to begin in 2016. Unlike Gotthard,
the Brenner will have a third central service tunnel 6 m in
diameter which has already been underway for some time in
order to explore the rock conditions. A 10.5 km drive from the
Italian end completed last year under an € 80 million (US$ 115
million) contract with a seven company Austro-German-Italian
consortium led by Pizzarotti and Condotte. Italy’s Seli supplied
the 130 m long support train behind a behind a 6.3 m diameter
reconditioned Aker Wirth cutter head.
A second drill and blast south from Innsbruck, Austria has so
far found better rock than expected giving hopes the main drives
might have better rock conditions than previously thought.
The Brenner is part of a key route for the Trans European
Network (TEN) from Palermo, Sicily to Berlin, Germany and
eventually Scandinavia. German Federal Railways is currently
building more than 20 tunnels on a new 85 km section of high
speed line between Nuremberg and Erfurt and more on the link
on to Leipzig.
Though mainly small, they include four significant projects on
the southern section, the 3.8 km long Eiberge tunnel and the 2.7

a wide ship canal with almost no cover. A huge concrete slab
has been poured into a dredged space in the canal bottom to
serve as a roof for the twin Mixshield TBMs from German
maker Herrenknecht. To deal with high water pressures in soft
sands and clays these are capable of working in pressure up to
4 atmospheres. The 7.5 m diameter drives are currently about
halfway.
Such machines pale into insignificance compared to the giant

bores – the first northwards drive is now
getting underway.
Such giant machines are becoming a
more familiar sight following the completion of a road tunnel
drive in Shanghai and another crossing of the Yangtze at Nanjing,
China.
Now one is likely to be seen in the US where the Washington
State Department of Transportation has signed a US$ 135
million contract for the Alaskan Way tunnel project in January
this year, with a joint venture of Dragados USA and Tutor Perini.
The scheme will create two large diameter 2.7 km long tunnels
to replace the existing waterfront elevated highway structure
through the busy city.
The two bores, one above the other would each carry two
lanes of traffic and have additional 2.5 m safety lanes. Design
build studies will determine the exact diameter but it will
be substantial. As the client points out “members of the team
delivered the comparable 49.5 ft (15.2 m) diameter Madrid
M-30 highway tunnel in Spain.”
Another giant TBM project reached breakthrough just north
of the US, on the Canadian side of the Niagara Falls. This time
the machine is a hard rock main beam machine from Robbins,
with a diameter of 14.4 m, which has battled through a difficult
10.5 km long drive for a new power supply tunnel for the Sir

safely scale down loose rock from the tunnel crown.
The Robbins machine managed to achieve two records for
11 m+ diameter boring - 468 m in one month, and 153 m in one
week. The Niagara Tunnel Project was initiated in June 2004 by
Ontario Power Generation and drives began in 2006. Two years
of work still remain for concrete lining.
Another major hard rock drive is just reaching completion,
this time in Manhattan, New York, US where the two machines
which began a complex of tunnels for the East Side Access in
2007 were due as iC went to press. The tunnels will bring trains
from Queens side of New York into a giant tunnel complex
underneath Grand Central Station. This is formed from four
upper and four lower tunnels created by forks in the access
drives. One Seli and one Robbins TBM made first a 2.1 km top
tunnel and then withdrew for a lower level branch to be formed.
The upper and lower tunnels then each split into left and right.
Below the station additional side branches were bored to create a
complex of four upper and four lower tunnels. The joint venture
of Dragados and Judau which constructed the tunnel now has a
US$ 500 million contract to excavate around the two levels of
four tunnels to make giant twin caverns for the underground
station which should see service in 2016.
In February, Manhattan also saw completion of the first
2.1 km long bore of the new Second Avenue subway line from
96th Street to 65th Street using a reconditioned Robbins TBM.
The machine has been pulled back and started the second slightly
longer 2.3 km drive for the twin bores in late March, the first
60 m through frozen ground. It will drive all the way to the end
of the first phase section at 63rd Street.
Meanwhile major tunnelling is underway in Mexico City where
a Robbins Earth Pressure Balance (EPB) machine, the largest in
the country at 10.2 m diameter is over 3.5 km along the route of
the capital’s Metro Line 12, the ‘Gold Line’.

The range of major tunnelling projects around the world certainly
paints the picture of an industry in good health – not only
because of the sheer number of schemes, but also the increasing
size and complexity of work being undertaken. And schemes like

The trend for larger projects with
complex demands is driving
innovation in the foundations sector.
A Soilmec SR-80 piling rig
installed displacement piles
that doubled as geothermal
wells for a hospital project
in Monselice, Italy.
Helen Wright reports on the latest
products and applications.
mbitious new projects are shaping the latest equipment
launches in the foundations sector and pushing the
limits of existing current machinery and construction
techniques.
Rising energy costs, for example, are driving architects to
improve environmental designs for buildings, and contractors
are increasingly specialising in challenging projects including
installing geothermal piles and wind turbine foundations.
Meanwhile, foundation equipment manufacturers report that
an increasing number of large infrastructure projects around
the world are fuelling demand from contractors for heavy,
multipurpose piling machines with large capacities.
In April, for example, IHC Fundex Equipment unveiled
the largest mobile piling machine it has ever manufactured in
response to a customer request. Weighing over 300 tonnes, the
FPD5000 has been designed for diverse methods of piling but
can also be used as a crane. IHC Fundex said the machine was
built for a customer in Brazil and will be put to work on the
construction of a new airport.
The FPD5000 can be used as a 275 tonne capacity crane
and can be modified with additional winches and cylinders to
become a dedicated pile driving machine, capable of working
with a maximum load of about 65 tonnes for the hammer and
pile.
The machine has a 29 m boom in pile driving configuration
and a standard 60 m length for lifting purposes. It can be
disassembled relatively easily into separate pieces – the body of
the machine weighs about 50 tonnes and is transported seperately
from the carrier and tracks.
A
Support network
Meanwhile, Soilmec has teamed up with Caterpillar to produce
its latest heavy duty model – the SC-65 lattice boom crawler
crane. Soilmec showcased a prototype at last year’s Bauma
Germany show, and the SC-65 has now
been brought to the market.
The machine has undergone extensive
testing and improvements have been
made to its design. Managing director
of Soilmec, Simone Trevisani, said that

Bauer tackles complex project Vietnam
auer Vietnam was appointed by contractor An Binh Star to carry out the main
foundation work for three main towers that form the hub of the Sanctuary Towers
complex in the Vietnamese capital, Hanoi.
Two Bauer BG 40 rotary drilling rigs, one BG 30 and two anchor drills began foundation
work in July last year on the a 28000 m2 site – the largest and most complex work that
Bauer Vietnam has taken on to date.
The project is scheduled for completion in August this year and includes a total of 640
bored piles ranging in diameter from 1 m to 1.8 m, together with 7500 m2 of nailed walling
as well as the excavation and construction of a two storey basement.
Based in Ho-Chi-Minh City, Bauer’s Vietnam subsidiary was founded in 2006 and only set
up an office in Hanoi in May 2010, but the first projects started rolling in shortly afterwards.

best Caterpillar technological solutions, specifically developed
for this project,” Mr Trevisani said.
“At Bauma 2010, the SC-65 was just a preliminary prototype.
Now it has been validated on the field, and some improvements
have been implemented thanks to feedback coming from the
jobsite,” he added.

weight of 25 tonnes at a dropping height of 29 m.
In addition to adapting to the scale of new infrastructure
projects, foundation contractors are increasingly tasked with
integrating environmentally friendly technologies to new builds.
PTC’s new Tiltex 60t clamp can tilt, grab
and lift sheet piles lying on the ground,
reducing man power on site.
Efficiency
Geothermal wells
On a € 165 million (US$ 236 million) project to construct
a new hospital in Monselice, Italy,
for example, the displacement piles
double up as geothermal wells.
A Soilmec SR-80 piling machine
was selected by contractor Trevi for the work
inserting 40 km of 600 mm diameter displacement piles at depths
ranging from 17 m to 24 m. Soilmec said it took on average 30
minutes to install each geothermal pile – drilling the hole took
just 8 minutes, but concreting and inserting the reinforcement
cage holding the geothermal loop required more time.
The thermal exchange between the surrounding soil and the
concrete piles is aided by the fact that the water table is located
immediately under ground level. For easy connection with the
future slab, concrete rings were placed on top of the piles to
compensate for the difference between ground and slab level.
The SR-80, which weighs 90 tonnes and can deliver 292 kNm
in torque, ensured good productivity – Trevi was able to install
an average of 16 piles, including the rig tracking phase between
piles, per day.
As governments worldwide invest in low-carbon, renewable
energy, the installation of wind turbines is another application
for which foundation equipment is increasingly in demand. In
May this year, for example, Bachy Soletanche won a UK£ 0.5
million (US$ 0.8 million) contract in the UK to install the piling
for four large wind turbines on a new wind farm. Located near
the Solway Firth in Cumbria, the Hellrigg Wind Farm is set to
contribute to meeting the UK’s target of 15% renewable energy
by 2015.
Contractor Hanson used Bachy Soletanche’s Heavy Duty Large
Diameter Auger (LDA) rigs and the piles are being constructed
with segmental casing and under a bentonite suspension due to
the properties of the soil and the unstable ground. Each base will
contain 16 900 mm diameter piles which vary in depth from
25 m to 38 m.
Bachy Soletanche contracts manager Steve Mallinson said the
project was one of the company’s more unusual jobs, “The site is
in a remote location and we are using large piling rigs and cranes
and making sure that there’s as little disruption as possible to the
surroundingg area”.
New equipment to improve the efficiency
of foundation works is also under constant
development. To ease the handling of sheet
piles, for example, PTC (part of the Fayat
Group) has produced a new concept of clamp, the
Tiltex 60t. Mounted on a PH Vibrodriver, the clamp can
tilt, grab and lift sheet piles lying on the ground helping to
reduceon-site manula labour.
With a clamping force of 60 tons (60.9 tonnes), the new Tiltex
provides a steady grip for heavy duty jobs. It can be used with
a wide range of PTC excavator mounted models including the
6PHFV, 8PHFV, 7PHF, 10PHF and 13PH.
Piling technology is also under constant review from equipment
manufacturers, and several new systems for complex applications
have been launched.
Liebherr has developed new software to help make deep
foundation work more efficient. The company’s deep foundation
machinery is equipped with Liebherr’s new PDE process data

Confined environments
A challenging underground car park project demands precision
n Hitachi ZX225USRLC-3 excavator has been put to work in a confined environment
on an underground car park project in Paris, France. The excavator, which is owned
by contractor Saperfe Travaux Publics, was fitted with a clamshell telescopic arm
and used to remove earth from depths of 21 m below ground level and load trucks that
transported the material offsite.
The excavator can dig to a maximum depth of 25 m and was used to remove a total of
65000 m3 of earth between September and November last year. Saperfe Travaux Publics
site manager Laurent Petain said a challenge for the ZX225USRLC-3 was working between
and around the pipes that held the car park’s outer structure in place.
“The pipes were required because the earth had a high water content and was therefore
relatively soft. The excavator worked in 5.5 m deep sections at a time and was required to
be extremely precise,” Mr Petain said.
The excavator’s short tail swing also helped as it meant trucks could stop directly
adjacent to it and be loaded straight away as material was brought up. Construction of the
six-level underground car park is scheduled for completion in October 2011.

Project required 20000 m of piles to be installed in 9 months
ontractor Marti Tunnelbau used
two Liebherr drilling rigs to install
a secant pile wall for slope and
foundation pit reinforcement for a project
in Switzerland. The 3.3 km Tunnel de
Choindez will run between the border of the
Jura canton and eastern Delémont district.
The 95 tonne LB 28 and 115 tonne LB 36
worked at the northern entrance, which is
300 m long, to install 20000 m of piles to
form a secant drilled pile wall. The length of
the 1020 piles is between 13 and 26 m with
a diameter of 1000 mm and the contractor
had nine months to complete instillation
The task was made easier thanks to the
low operating weight of the machines,
which can be transported in one piece,
allowing for flexibility on site. The LB 28 is
equipped with a 286 kNm rotary drive and
the LB 36 with a 366 kNm rotary drive. Both
units can drill to a maximum diameter of
3 m and a maximum depth of 70 m. The
machines are equipped with a Kelly winch
and rope crowd system with 40 tonnes
of pull force, making them well-suited to
operating in the most difficult soils.
Liebher said the project was completed

Latest earthmovers
Caterpillar’s new ADTs,
graders and scrapers
for the European and
US markets feature
fuel-efficient Interim
Tier 4/Stage IIIB low
emission engines.
Caterpillar’s new range-topping ADT, the 740B.
Helen Wright reports.
aterpillar has launched a new
generation of articulated
dump trucks (ADTs),
together with a new graders and
scrapers, all of which comply with
the latest engine emissions laws in
Europe and the US.
The new machines include three
new ADTs - the 735B, offering
a 32.7 tonne payload, the 740B
with its 39.5 tonne payload, and
the 740B EJ with an ejector body,
carrying a 38 tonne payload.
All three are powered by
Caterpillar’s US Interim Tier 4
and European Stage IIIB certified
engines, which use cooled exhaust
gas recirculation (EGR) to help cut
soot - particulate matter (PM) - and
nitrous oxide (NOx) emissions. The
smaller, 735B is powered by a
337 kW engine, while the two
larger trucks are powered by
365 kW engines.
C
Caterpillar’s European product
specialist, Rob Macintyre, described
the new generation as, “The most
significant upgrade since 2000,”
and highlighted several changes in
addition to the new engines.
The front end of the machine
has changed to accommodate the
EGR system, and Caterpillar took
the opportunity to reposition the
headlights, which have been wider
set for a better spread. The front
bumper’s durability has also been
improved to better tackle the most
aggressive applications and now
includes a fully enclosed belly
guard.
Caterpillar has also automated
its differential lock system. The B
series features Automated Traction
Control (ATC) - a proportional
differential locking system
that adjusts itself to different
transmission loads.
“The automatic system leaves the
operator free to concentrate on
driving the truck, without having
to think about how to gain the
best traction in different ground
conditions,” said Mr Macintyre. He
added that the proportional ATC
system works in harmony with the
hydraulic steering system without
compromise in tight turning
manoeuvres.
Caterpillar has also launched four
new motor graders. In line with
its other launches, the 140M2 and
160M2, along with their all-wheeldrive (AWD) counterparts, the
140M2 AWD and 160M2 AWD,
are also equipped with engines
meeting Stage IIIB/Interim Tier 4
emissions standards.
The latest models have a wider
net-variable-horsepower range than
their M Series predecessors. The
140M2 and 160M2 have power
ranges of 144 kW to 181 kW and
159 kW to 196 kW respectively. Net power ratings for the 140M2
AWD and 160M2 AWD are
151 kW to 181 kW and 166 kW
to196 kW, respectively.
The M Series 2 is designed
for a broad range of tasks,
including heavy blade work,
road maintenance, ripping and
precision-finishing applications.
Also new are three wheeled tractor
scrapers. Production of the 621H,
623H and 627H machines begins
in August and each model will be
available with Interim Tier 4 and
Stage IIIB-compliant engines.
The 621H and 623H are
single-engine machines, while the
open-bowl 627H has twin enginesone on the tractor and one on the
scraper-and all wheel drive.
Caterpillar product and
application specialist Ángel Luis
González Suárez said a main
advantage of these machines is that
they are fast and comparatively
cheap to run. “Using the push/pull loading
method, two scrapers can be fully
loaded in 40 seconds,” said Mr
González Suárez. “The idea is that
they are the lowest cost way to
move material”.

Brand new heavies
Volvo has launched new
generations of its ADTs
and some of its largest
excavators and wheeled
loaders, in response to
new engine emissions
laws in Europe and
the US. Helen Wright
reports.
Volvo’s new L150G has been
designed as a good loading match
for on-highway trucks.
olvo Construction
Equipment has launched
new wheeled loaders,
excavators and articulated haulers
to comply with Europe’s Stage IIIB
and US Interim Tier 4 emissions
regulations.
The machines are powered
by Volvo’s latest V-ACT
(Volvo Advanced Combustion
Technology) diesel engines, with
cooled exhaust gas recirculation
(EGR) to reduce nitrous oxide
(NOx) emissions and a diesel
particulate filter to remove soot
(particulate matter). The filters
have an active regeneration feature,
which burns off the soot collected
in the filter when it reaches set
limits.
This technology has helped to
produce fuel savings of up to 15%
on some machines, notably the
company’s first 35 tonne wheeled
loader, the L250G.
Designed to be a good loading
match for on-highway trucks,
the L250G is fitted with Volvo’s
290 kW turbocharged engine.
The company has optimised
the engine’s performance to
transmission and driveline, and
this has helped to drive fuel
savings, as has the use of loadsensing hydraulics.
V
Fuel efficiency
Arvid Rinaldo, Volvo Construction
Equipment’s global market
communications manager, said
the new engines combined the
company’s core aim of lowering
the environmental impact of its
machines and improving fuel
efficiency across its range.
“We see this new legislation
as very positive and have fine
tuned our technology using the
experience available from the
whole Volvo toolbox.
“The impact on the end user
is minimal. Regeneration of
the particulate filter is totally
automatic, and the filter is changed
as part of a normal service after
4500 hours,” he said.
Also new from Volvo is the
L180G high lift wheeled loader.
This machine is fitted with a
246 kW Tier 4 Interim/Stage IIIB
compliant engine that is married
to drive train, hydraulics and
the lifting arm systems and has
also demonstrated fuel efficiency
savings of up to 15%.
Other new Interim Tier 4/
Stage IIIB machines include the
first examples of Volvo’s D-series
excavators, the EC380D and
EC480D tracked excavators. These
cover the 38 tonne to 50.5 tonne
operating weight classes and have
been designed for heavy digging
and lifting operations.
The EC380D is powered by a
208 kW engine, while the larger
EC480D is powered by a 245 kW
engine. Both machines feature
an automatic idling system that
reduces engine speed when the
levers and pedals are not activated
- aiding fuel efficiency.
Now also available in Europe
are the 28 tonne EC250D and
33 tonne EC300D excavators.
Their Interim Tier 4 /Stage IIIB
engines deliver fuel efficiency
improvements of between 9% and
13%.
Also new are the F-Series
articulated dump trucks (ADTs).
Ranging from the 24 tonne A25F
up to the 39 tonne A40F, they
feature an Automatic Traction
Control (ATC) system as standard
which automatically disengages
the rear axle when not needed,
eliminating tire skid when
cornering and reducing tire wear,
but which kicks in again when it
senses slippage.
The new F-Series haulers also
meet the requirements of Stage
IIIB and Tier 4 Interim emissions
legislation, and are said to be
4% more fuel efficient than their
E-Series predecessors.
Future technologies
Volvo plans to launch more than
50 machines this year, many in
response to this year’s new engine
emissions legislation. However, the
company remained tight-lipped
on its plans for meeting the even
stricter Stage IV/Tier 4 Final
emissions legislation that come
into force in Europe and the US
in 2014. Mr Rinaldo said future
technologies would be based on
knowledge throughout the Volvo
group, including the development
of hybrids and the use of selective
catalytic reduction to further
reduce NOx.
“The legislation in 2014 will
continue to drive the complexity
of our products, and as well as
considering every option that is
currently available to optimise
every part of the combustion
process, we are also developing
new technology all the time,” he
said.

range is the result of a three
year research and development
programme and a € 3 million
(US$ 4.2 million) investment. The
first fruits of this research are at the
smaller end of the scale with six
models in three weight classes from
1.5 to 1.8 tonnes.
Visitors to last year’s Bauma
exhibition may remember seeing
B
an early version on display on the
Bomag stand, but according to
communications manager, Iris von
Kirschbaum, this was a “Proto,
proto, prototype.” She added,
“This is a real core product for
Bomag.”
Feedback received at the show
and subsequently from customers
led to several key design changes,
among them the provision for
more foot space, easier access and a
more expansive operator area.
Other improvements around the
operator include a chassis frame
that tapers towards the operator
station. This means the edge of the
front drum is visible without the
operator having to lean over the
side of the machine – an important
safety feature.
The small, ergonomically
designed steering wheel and multifunction joystick work alongside
Bomag’s intelligent vibration
control. Once the operator has
The ‘side clearance’ models have
drums supported on just one
side, so they can work up against
obstacles like walls or high curbs.
The new chassis design means
the operator can see the edge of
the drum without leaning out of
the machine.
selected vibration on the front,
rear or both drums, along with
the intelligent vibration mode,
vibration is activated based on the
roller’s speed. Vibration kicks-in
at 1 km/h but will turn off again if
the roller is going too fast – above
5km/h.
The first models available in the
Dash-5 range are the 1.55 tonne
BW 80 AD-5, the 1.60 tonne
BW 90 AD-5 and 1.65 tonne
BW 1000 ADM-5. In addition
to these basic models, there are
the 1.65 tonne BW 90 SC-5 and
1.70 tonne BW 100 SC-5 ‘side
clearance’ models, where the drum
is supported on just one side, to
allow compaction right up against
high curbs or other obstacles.
The 1.7 tonne BW 100 ACM-5
combination roller rounds-off the
range.
Power for all of these models
comes from a 15 kW Kubota
engine, which is designed for use
in Europe and requires ultra-low
sulphur diesel fuel to operate and
meet the region’s laws on low
emissions.
The operator’s station has been
designed to give easy access and
plenty of foot room.
The maximum travel speed
for the machines is 10 km/h, an
increase of some +25% on their
predecessors, and at 30 litres, the
fuel tank is +30% bigger, providing
enough capacity for a full day’s
work.
Finance options
Bomag says it expects each
machine to be kept by its original
owner for an average of eight to
ten years. In the past, it has seen
even longer ownership periods. To
reflect this, it is offering a range of
finance packages that move away
from the typical 20% deposit
and 36 month hire-purchase
agreements that Ian Barker, general
manager of Bomag finance in the
UK, says typifies the industry.
“We are advocating a five-year
funding package, better matching
income to expenditure,” he said
Additional Dash-5 rolers are due
to be launched later this year in
Europe from Bomag’s main factory
and headquarters in Boppard,
Germany. For other parts of the
world, including China and the
US, Bomag manufactures the
BW 900/50, a 1.2 tonne machine
powered by a Honda petrol engine
at its plant in China.

to Junttan’s X series piling rigs.
and they are said to reduce noise
by -10 dB, while Junttan claims
+9% to +18% higher productivity
along with better adaptability as
the same hammer can be used on
several sites.
The hammers are suitable for
driving steel tube, sheet piles,
pre-cast concrete and timber
piles. The stroke and blow rates
are adjustable to optimise the
pile driving performance in all
conditions. The ram weight can
also be changed depending on pile
type requirements. The hammers
can be mounted on all kinds of
leaders, or can be freely suspended,
the company said.
Junttan hydraulic impact
hammers are said to have low
environmental impact. The
company claims that 95% of the
hammer’s energy is transferred to
the pile. Also, it said that a smooth
installation process helped ensure
that there was as little adverse
impact on the environment as
possible.
New piling rigs,
hammers and a new
look were unveiled at
Junttan’s 35th birthday
celebrations. Sandy
Guthrie reports.
new PMx24 piling rig has
been launched by Junttan
as part of the X series
that was first seen at the Bauma
exhibition in Munich, Germany
last year. The company has also
introduced the SHK110-5/7
hydraulic hammer - the Shark which was shown in a concept
form at Bauma.
A
Birthday
The Finnish-based hydraulic piling
equipment manufacturer has also
marked its 35th anniversary with
a new look, including an updated
logo and a revamped website.
It said the information on the
website had been substantially
increased and made easier to use.
The X series of piling rigs was
introduced at Bauma in the form
of the PMx20. The range now
consists of the PMx22, PMx24
and PMx25, replacing previous
models up to the PM25H.
Junttan says its X series
incorporated modern
manufacturing technologies and
materials for extended reliability
and improved performance.
The Junttan X control system
is purpose built and controls all
the vital rig functions, providing
features for adjustment, operation
and maintenance.
With a maximum pile length of
24 m, the PMx24 it has an average
working weight of 68 tonnes. The
recommended ram weight is 4 to
6 tonnes, and the engine power is
179 kW.
The smallest X series model,
the PMx20, also 179 kW, has
an operating weight around 55
tonnes, a maximum pile length
of 20 m and a recommended ram
weight of 3 to 5 tonnes.
Pile hammers
The SHK series of hydraulic
hammers is nicknamed Shark,
Full range
Following its appearance as a
concept at Bauma, the SHK series
now covers hammer sizes from 3 to
9 tonnes.
The Shark hammers have a
maximum drop height of 1.2 m
and run at either 50 to 120-plus
blows per minute or 60 to 100plus blows per minute.
Junttan hammers are also used
without Junttan rigs. For this,
the company manufactures
hydraulic power units, and it has
just launched the 10XCU. This
is said to use the same advanced
technology as the other Junttan X
series products.
The smallest of its powerpacks,
the 10XCU claims easy handling,
durability and good fuel economy,
as well as low noise.
It uses Junttan’s latest control
technology to manage the piling
process, and it replaces the 10CCU
model.
