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.

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. GENERAL NOTES-SOUND BY DESIGN WALL SYSTEM-MTO-SPECIFICATIONS 8/05/09 6 DESIGN CONCRETE SYSTEMS LTD. GUIDELINE SPECIFICATIONS 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. GENERAL NOTES-SOUND BY DESIGN WALL SYSTEM-MTO-SPECIFICATIONS 8/05/09 7 DESIGN CONCRETE SYSTEMS LTD. GUIDELINE SPECIFICATIONS G6 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.
