Plan Sheet / Specification Reference= Bid Item # 95; 90" Diameter CIDH piles, Contract plan sheets 441, 499, 532, 567, & 599, Details for 90" Piles


Question = The current arragement of reinforcing steel vertical bars, in all cases, does not allow for proper placement of the PVC inspection pipes. For 3" clearance on each side of the inspection tube, you must have at least 8 1/2" clear between the vertical reinforcing bars. In Section 'C-C' on plan sheet 441 you only have 5 5/8" clear and 6" clear on Section 'B-B' for balance of piles. The current design may lead to restricted concrete flow to the outside of the rebar cage and must be addressed. Will the current rebar design arrangement be changed to comply with the States own design criteria for PVC tube placement?
