Concrete Barrier - what is the definition of permanent and does it apply to our noise wall system? System is comprised of removable and replaceable components between permanent structures (structures are wide flange beams).
Noise Barrier - For reflective noise walls, bottom of the upper panels are of the same lot.
Structure - Our noise wall system utilizes wide flange beams that carry the load. Precast panels do not carry load and are not permanent.
Page 4 of 42: 1355.04.01.02 - Concrete Mix Design - Refer to note 1355.07.01 regarding mix design exception.
Page 6 of 42: 1355.05.03 - Associated Hardware - Please define 'associated hardware' and does this include lifting hardware?
Page 8 of 42: 1355.07.01 - General - Our reflective noise wall system, inclusive of the bottom panels, is produced using drycast methodology. please add an exception.
Page 9 of 42: 1355.07.05.02 - Welding - Several noise wall products are fabricated by resistance welding (mesh) and should be exempt and follow CSA standards for resistance welding.
Page 10 of 42: 1355.07.09.01 - Wet Cast Concrete - c) & d) - can we investigate the feasibility given the sizes of our panels and discuss special dispensation of our noise walls?
Page 11 of 42: 1355.07.10.01 - General - Can an exception for noise wall be provided when manufactured as vertical pours align similar to the culvert dimensions. This would be for large format panels.
Page 12 of 42: 1355.07.11.01 - Curing General - what is the 'm' in the first sentence? minutes? used elsewhere in the report as metres. Concrete finishing and applying moist curing system cannot be applied in the allotted duration.
Page 14 of 42: 1355.07.11.04 - Records of Inspection of Moist Curing - c) - what options for visual record are accepted such as using a screen shot from video cameras?
Page 16 of 42: 1355.07.17 - Markings Stenciled - Given the amount of pieces a day, would alternative identifiers such as tags be considered?
Page 21 of 42: 1355.07.22.04.07 - Coring for Acceptance Testing - regarding the edge distance, we are typically limited to a 500mm noise wall panel. There is potential of steel in the sample (mesh).
Page 22 of 42: 1355.07.22.04.09 - Salt Scaling Sawn Samples - Does this exempt noise walls as reflective noise walls are patterned both sides.
Page 41 of 42: Table 8 - 5) - Bottom panels and upper panels are of the same lot. Should not be considered separately.
