Design Sound Reflective Noise Barrier Systems complete. The manufacturer of
Sound By Design is Design Concrete Systems Ltd. P.O. Box 839, 40 Birch
Street, Seaforth, Ontario, Canada N0K 1W0
1.2
The barrier system and its components shall be designed in accordance with the
requirements of the “Canadian Highway Bridge Design Code”. The “Reference

1.3
The manufacturer of the barrier system shall prepare detailed layout and
fabrication drawings including pertinent specifications thereto, together with the
complete engineering calculations. The manufacturer shall submit to the
Contractor or Owner’s Representative six (6) sets of drawings and specifications,
sealed by a Licensed Professional Engineer, for approval prior to
commencement of manufacture or construction.
1.4
The Contractor or Owner’s Representative shall establish the alignment of the
wall, the top of wall elevations and final ground line elevations at the bottom of
the wall. The manufacturer shall use these elevations to develop the layout and
fabrication drawings including complete elevations of each wall indicating top and
bottom of wall elevations. The final ground elevations and wall alignments
established in the field shall be protected by the Contractor for the duration of the
project and shall not be adjusted without prior approval of the Engineer.
1.5
The Contractor or Owner’s Representative shall carry out site investigations to
determine soil parameters, water tables, location of underground services and
above grade obstructions. The manufacturer shall use these parameters to
determine the depths, sizes and locations of footings.
2.
MATERIALS
2.1
Panel Construction: Sound By Design panels shall be of a homogenous, steel
reinforced, zero slump concrete mixture. They will have the dimensions and
specifications shown on the contract drawings. The panel design shall be sealed
by a Licensed Professional Engineer.
2.2
Acoustical Characteristics: Sound By Design Panels shall be reflective on
both faces. The Sound Transmission Class (STC) of the Sound By Design
Panels shall be equal to or greater than 32 as determined in accordance with
ASTM E90-75.
2.3
Aesthetics: Sound By Design Panel face colours and textures shall be as
specified in the Contract Documents. (Owner to specify colours, percentages of
each colour, colour pattern, texture, on one or both sides and percentage of
textured panels)

2.5
Steel Posts: Steel posts shall be hot rolled wide flange structural sections in
accordance with shapes, sizes, details and method of connection as shown on
the drawings. All structural steel work to comply with CSA Standard S 16 and
grade of steel shall be G40.21-M 350W. All welds shall conform to CSA
Standard W59 and CSA Standard W47.1. All steel components to be hot dip
galvanized after fabrication in accordance with CSA Standard G164-M. The post
design shall be sealed by a Licensed Professional Engineer.
2.6
Post Footings: Concrete in augered footings shall be minimum 20 MPa and in
non-standard, engineered footings, it shall be 25 MPa, all in accordance with
OPSS 1 350.
3.
CONSTRUCTION
3.1
Site Grading and Preparation: Grading, (cut and fill) and berm construction
which is associated with the barrier installation shall be completed to within
25mm below the bottom of the barrier wall prior to construction of the barrier
footings. All grading shall be in accordance with OPSS 206. Berms shall have a
profile with a minimum 3.0m flat top and maximum side slope of 3:1. After
completion of wall panel installation, final grading shall be to bottom of wall and
there shall be no visible gaps between bottom of wall and top of final grade. Tree
pruning and removal shall be kept to a minimum. Materials excavated from
footing holes, if acceptable, may be deposited on the adjacent terrain and spread
in uniform layers. Surplus excavated material shall be disposed of at the
contractor’s expense.

G5
Alignment and bottom elevations of wall shall be clearly marked and staked prior
to commencing with construction of wall footings. Grade stakes shall be placed
at approximately 25m on center and at all grade changes, wall steps, starts and
ends of wall and alignment changes. Grade stakes shall show the following
information: station number, bottom of wall elevation, cut or fill dimension and
offset to centerline of wall. Below grade service lines (hydro, telephone, gas,
water, drainage, etc.) located within 1.0m of the noise barrier wall or footings,
shall be clearly marked by stakes.
3.2
Footings: The depth, type and size of the footings shall be shown on the
drawings and shall be designed and approved by a Licensed Professional
Engineer with reference to the soil strength parameters and site conditions
supplied by the Owner’s Representative for the project. The concrete in the
footings shall be cured for a minimum of 5 days before work which places stress
on the posts may be carried out. The tops of all footings are to be shaped and
leveled to provide full horizontal seating of the bottom panels and the remaining
surface of the top footing shall be domed to allow the shedding of water.
3.2.1 Cylindrical Footings: Concrete for footings in augered holes shall be cast
entirely against undisturbed soil.
3.2.2 Non-Standard Engineered Footings: Where site conditions dictate
special footings in large hole excavations (e.g. Other than augered holes), the
non-standard footing shall be designed and sealed by a Licensed Professional
Engineer. The excavation shall be backfilled with granular material and
compacted, all in accordance with OPSS 501.
3.2.3 Stepped Footings: Where grade changes require the bottom of the wall to
be stepped, the top of the footing shall be constructed as shown on the drawings
and as per Manufacturer’s recommendations.
3.3
Posts: The posts shall be installed plumb to within +/- 10mm of vertical in 5.0m.
They shall be located to the lines and grades specified on the drawings to within
a tolerance of +/- 10mm. Any accidental coating of concrete on the above grade
surfaces of the posts shall be washed off on the same day of installation.

3.3.1 Steel Posts: A concrete leveling pad shall be poured into the bottom of the
augered hole 4 hours prior to inserting the concrete post. This pad shall serve to
support the concrete post at its proper elevation and alignment during pouring
and vibrating of the footing concrete around the inserted post. Galvanized
surfaces which are abraded shall be cleaned and the abraded surfaces touched
up using soldering or thermal spraying in accordance with OPSS 911.
3.4
Panels: The Sound By Design Panels shall be installed according to type,
colour, texture and length as shown on the drawings and in accordance with
Manufacturer’s recommended practices. Each panel is identified as to its type
and orientation in the Noise Barrier Wall. The contractor shall take care and
provide adequate protection when handling, moving, and storing the panels to
prevent staining, marking, chipping or spalling. To lift and place the Sound By
Design Panels, only the lifting device provided by the manufacturer or an
approved equivalent shall be used. Touch up and repair is at the contractor’s
expense and shall be carried out in accordance with the Manufacturer’s
recommendations or at the Engineer’s direction. The bottom panel shall be fully
seated on the footing. Top of footing shall be free of foreign material, ice, snow
or water. Horizontal joints of adjacent panels shall be lined up to a vertical
tolerance of +/- 4mm. Where vertical adjustments are required for alignment, a
mortar base shall be used. Intermediate panels shall fit tight to the panel below.
The tongue and groove detail shall mesh fully, be free of foreign material, ice or
snow and there shall be no visible gaps.

QUALITY ASSURANCE
4.1
Aesthetics: The visual appearance of the Noise Barrier Panels, in terms of
colour, pattern and texture, shall be uniform when viewed at a distance of 15m
from the face of the wall. Any visual blemishes shall be repaired and touched up
as per Manufacturer’s specifications.
4.2
Performance: The contractor shall, at his expense, supply to the Owner or the
Owner’s Representative, one panel per thousand panels supplied or a minimum
of three panels for testing to verify structural strength, sound reflection, weather
resistance and durability in salt scaling and freeze thaw.
5.
MEASUREMENT FOR PAYMENT
5.1
Measurement for the above items is by Plan Quantity as may be revised by
Adjusted Plan Quantity, for the length in meters, of the specified height of the
noise barrier. Transitions between different barrier heights will form part of the
higher barrier.
6.
BASIS OF PAYMENT
6.1
Payment of the contract price(s) for the above tender item(s) shall be full
compensation for labour, equipment and materials necessary to construct and
complete the noise barrier work and to provide test panels upon request.
