Provide horizontal "L" shaped corner bars of same cross section and spacing as horizontal bars or welded wire fabric around wall and grade beam corners. Cover electrical conduit, ductwork or piping buried in slabs with 600 mm wide strip of 102 x 102 x MW13.3 x MW13.3 welded wire fabric. If principal slab reinforcement is placed above conduit then place 600 mm strip under conduit. Position of reinforcing steel takes precedence over conduit, ductwork, or piping. PLACEMENT Place reinforcing steel as indicated on reviewed placing drawings and in accordance with CSA A23.1. Chair slab reinforcing not further apart than 1.2 m in either direction. Place, support and secure reinforcement against displacement. Do not deviate from required position. Do not displace or damage vapour barrier. Repair and reposition vapour barrier as required. Use plain round bars as slip dowels in concrete. Paint portion of dowel intended to move within hardened concrete with one coat of asphalt paint. When paint is dry, apply a thick even film of mineral lubricating grease. Prior to placing concrete, obtain of reinforcing material and Minister’s approval placement. Ensure reinforcement location is maintained to provide required concrete cover to reinforcement during placement of concrete. Place reinforcing steel in [ ], [ ] [, and] [ ] to provide concrete cover for [ ] hour fire endurance, as required by the Alberta Building Code. Protect [epoxy] [and] [paint] coated portions of bars with covering during transportation and handling. Place reinforcing steel to provide concrete cover as follows: Item Cover [mm] Beam Stirrups [40] [ ] Supported Slabs and Joists [20] [ ] Column Ties [40] [ ] Interior Walls [25] [ ] Walls Exposed to weather or backfill [50] [ ] Footings and concrete formed against earth [75] [ ] Slabs on Fill [50] [ ]
