Our story is that of urban regeneration and conservation, and of how our
company has evolved to become a market leader, who over the years
have collaborated on many of the high profile projects that have led to the
transformation of Dublin.
Hegarty Demolition Ltd was formed in 1990 in response to the massive
growth in Urban Development experienced by Sean Hegarty Earthworks
which had been founded 20 years earlier, specialising in earth moving,
site development, civil engineering and plant hire.
Hegarty Demolition became a Complete Service Provider, the recognised
expert in demolition, basement construction, conservation and civil
engineering. Its involvement in prestigious commercial projects such as
the redevelopment of Temple Bar, Croke Park and the Dublin Docklands
has since established it as the market leader in these areas.

Retention and Temporary Support
3 Basement Construction
Hegarty Demolition was the contractor of choice when Spain
Courtney Doyle needed an experienced and specialist team to
undertake a €4m mixed development at Orwell Road, Rathgar.
The development – which comprised a mix of basement car
parking, retail and residential units – showcases the many
diverse specialties that the company can bring to a wide range
of contracts.
The project involved the construction of a reinforced concrete
structure to include external retaining walls to ground level, and
core walls and partitions to roof level. The external walls are a
pre-cast patented system designed, manufactured and shipped
to site by the German company Betoform GmbH. The units were
hoisted, erected and propped by Hegarty operatives under the
guidance of the manufacturers.
The comprehensive schedule of works included selective
demolition, reduced level excavation, basement construction,
general construction and the completion of all works to fitout stage.
Hegarty Demolition carried out all finishing works up to fit-out stage
including roofing, mechanical & electrical installation, passenger
lifts, hard landscaping and the reinstatement and making good to
all adjoining properties. A feature of the works was the construction
of a double A roof, finished with natural slates on timber trusses
constructed from salvaged pitch pine timber all braced with a
system of metal brackets and stays reflecting the original roof.
The site originally contained a two-storey period type retail outlet
on one street frontage and a garage with filling station on the
other. These buildings were demolished, while retaining the
period façade, and all surrounding buildings were weathered and
supported. A reduced level excavation and dig for a single storey
basement and a variety of retention systems were implemented to
suit several adjoining properties and roadways.
The basement structure required the installation of a system of
4.0m deep rotary bored piles to include Gewi high yield steel
anchors as a rock anchoring for the structure.
Hegarty Demolition carried out these works as the main contractor
working in a very busy environment and surrounded by several
adjoining owners to a very strict programme and without claim
or complaint.
The works were completed without hitch and in complete harmony
with the client’s in-house design team.

A reputation for integrity and reliability is key to the success of
Hegarty Demolition, and it was in recognition of this fact that
Park Development Group chose our company for an extremely
challenging project spanning a time frame of five years.
As part of the Group’s €300m mixed development at New Bancroft,
Tallaght, Hegarty Demolition was selected to carry out site
enabling works and basement excavation – to include earthwork
supports, basement construction, de-watering, waterproofing,
and a considerable amount of shell and core construction in a
phased programme.
Phase I of the project involved a basement construction including
all associated under-floor drainage, outfall drains and road
crossings and the like. A full Traffic Management Plan and liaison
with the Local Authority was provided, coordinated and managed
by ourselves. The structure was completed on time and within
budget which precipitated negotiations to proceed onto the next
phase of the project.
Phase II – a two-storey basement structure, 7,000m2 in area,
was finalised and commenced immediately after Phase I. Many
challenging issues were encountered and resolved on this
sloping site, which was again surrounded by existing structures
and a busy road network. Innovative problem solving and
exhaustive pre-planning procedures meant that particular
engineering concerns regarding de-watering were anticipated and
successfully overcome.
Hegarty Demolition was subsequently appointed to carry out shell
and core construction for superstructure works, hard landscaping,
installation of services and other infrastructure works. The entire
€15m contract was completed on time and within budget.

Demolition - Pelican House, Mespil Road
When Hegarty Demolition was contracted to demolish the
Pelican House building on Mespil Road, the company’s technical
knowledge saved its client both time and money.
1 Secant Piling and Support System
2 Deep Basement Excavation
The building was a six-storey reinforced concrete structure with
pre-cast cladding on the front façade. Its overall height of 20m
allowed the use of 35 tonne excavator fitted with a “long reach”
(22m) demolition arm, which is proven to be the most costeffective method of demolition where adequate space is available
to operate this size of equipment. Following “soft-stripping” of
the building, this method provided an efficient means of breaking
out all the concrete elements and processing the materials
for recycling.
The hydraulic concrete pulveriser used with the demolition arm
munched the reinforced concrete elements – slabs, beams
& columns – in pre-programmed sequence from the top to the
bottom of the building. This allowed the separation of re-bar and
the salvage of reinforcing steel as work progressed.
Following demolition and site clearance Hegarty Demolition Ltd.
proceeded to carry out:
l Deep dig excavation for this three storey basement, where
66,000m3 of soil was removed to a pre-planned tiered schedule,
and removed offsite for disposal. Also included was the removal
of 12,000m3 of rock.
l The design, erection, maintenance and removal of a temporary
support system to support the site along the busy Mespil Road
and adjoining office buildings to a depth of 8.5m.
l The management, pumping and treatment of the very heavy
ground water found on site.
This project was completed safely and efficiently in the most costefficient and environmentally-friendly manner possible.

Refurbished Grafton Street Facade
When a major urban development is taking place – and 44
adjoining owners and leaseholders all have to be kept on board –
it’s essential that all problems are anticipated and solutions found
before any works can commence.
This was the challenge facing Hegarty Demolition when it was
contracted to convert the former Brown Thomas landmark
premises into a modern shopping complex. Demolition works
included the selective removal of old three and four storey
buildings, the retention of protected facades on Grafton Street,
Duke Street and Duke Lane, the retention of a protected building
on Duke Lane (while constructing a basement underneath) and
the protection of retained buildings on Duke Street.
A modular steel frame support system was erected on all facades
(15m high) over footpaths, with canopies and fans to protect
pedestrians. In this busy urban location all 44 adjoining owners/
leaseholders were dealt with and the project planned in detail to
ensure uninterrupted continuation of business in buildings and
shops surrounding the site.
Strict Health & Safety measures were implemented and
environmental controls put in place to monitor all aspects of the
works, i.e. noise and vibration levels, dust emissions and Code
of Conduct for all site operatives. Incidentally, this was one of the
first projects where smoking on site was prohibited. Demolition
in these sensitive locations was labour intensive and the removal
of rubble and debris took place outside normal trading times –
mostly at night and early morning.
Enabling Works included basement excavation, underpinning
retained adjoining buildings, earthwork support systems, pumping
& dewatering. An intricate temporary works system was erected
under No. 5 Duke Street (protected structure). This allowed the
excavation and construction of a double basement.
The full scope of the Enabling Works was completed skillfully
and professionally to a tight programme schedule in an active
and busy commercial location without a hitch or claim from
adjoining owners.

civil Engineering - Spencer Dock
This urban regeneration project by Spencer Dock Development
Company Limited involved substantial demolition and site
clearance at the former C.I.E. terminal building and Campshire
sites on North Wall Quay. Extensive basement excavations
were carried out to service both the new Price Waterhouse
Headquarters block and the National Convention Centre.
This involved the management, excavation and removal of 150,000
cubic metres of materials including disposal of a large volume of
hazardous material to licensed facilities in Ireland and abroad.
An extensive pumping and dewatering system was set up for both
basements which extended to 14m deep in this tidal site.
As part of the overall site development, a section of the Royal
Canal bounding the site was remediated and realigned.
This involved damming, clearing, constructing of various bunding
configurations for flow management, over-pumping, installation
of settlement tanks and the removal of all silt and accumulated
fill from this section of the canal. These materials were heavily
contaminated and were subject to rigorous examination and
categorizing before disposal at relevant disposal outlets, again
in Ireland and on the continent. Included in this diverse package
of works was extensive civil engineering and infrastructure works
in the complete development of this 50 acre plus city centre
site involving:
l Modification and addition to existing utilities on the busy
port roads surrounding the site, involving road openings,
traffic management and liaising with all the Local and Civic
Authorities.
l Installation and testing of 3.50 km of various watermains and
associated fittings.
l Installation of 25km of service ducts for new utilities.
l Construction of 7,000m2 of site road network including all
preparations.
l Provision and placing of 4,000m2 of natural stone paving along
with 1,200m of kerbing to include preparation and protection.
l Installation of 2km of surface water drainage along with
outfall manholes into the Liffey. A similar amount of foul
drainage was installed along with connections to main
drainage systems on New Wapping Street. These works
were carried out in conjunction with officials from Dublin
City Council.
l We also worked closely with other contractors in forming a path
for new Luas line, involving sweeping the line path for services/
containments and the construction of service ducts, bases,
sub-base and the like for the new railway line.
These extensive works, valued in excess of €25M, were carried
out in complete harmony and in an unbroken programme of 5
years under the main contractors – CMP.

3 Aerial View of Remediated Site
Hegarty Demolition have undertaken an extensive range of site
remediation projects in recent years. These works require very
specific technical knowledge to ensure that they are carried out to
the highest international standards.
One such contract was the remediation of the 24 acre site of the
former Irish Glass Bottle Company in Ringsend in 2008. Prior to
the construction of the glass manufacturing facility this site was
previously a local authority dump operating until the mid 1960’s.
The contract involved the preparation of a detailed Health & Safety
plan for the management of this toxic site, which included the
disposal of heavily contaminated materials, trapped toxic gases,
contaminated water and vermin control.
In remediating the site, the team broke up approximately
250,000 tonnes of concrete substructure and hardstandings,
crushed these arisings to the required grading and specification
and used them to cap the newly exposed formation. The balance
was stored on site for re-use in the follow-on site development.
A volume of approximately 550,000 tonnes was then excavated,
loaded and shipped to Germany for processing and disposal.
The site was left neat, tidy and remediated for follow-on
development.
The Hegarty team – trained to the highest international standards
– carried out this dangerous work while minimising risk to
themselves and the general public
