Q) MDCI ANTICIPATES CONSTRUCTING THE CIDH PILES USING THE SLURRY DISPLACEMENT METHOD. SECTION N-N SHOWS HORIZONTAL HOOKS AT THE TOP OF THE REINFORCEMENT. MDCI REQUEST THAT THE ENGINEER MODIFY THE HOOKS SO THAT TOOL CASING MAY BE EXTRACTED WHEN REQUIRED. IF THE MODIFICATION PROVIDES FOR THE HOOKS TO BE TURNED IN, PLEASE ALLOW FOR AN 8 IN. DIAMETER MINIMUM ACCESS HOLE AT THE TOP OF THE REINFORCEMENT TO ACCOMMODATE THE PUMP TUBE AND WATER PUMP.
A) The hooks cannot be turned in and at the same time leave an 8-inch diameter access hole, because it would produce excessive overlapping of the bundled reinforcement. The reinforcement would have to be bent at different levels and the development length would be reduced. To facilitate the extraction of the tool casing, the #19 reinforcement can be placed straight up and then bent in the field after the work in the pile is completed. There is no need for the tails of the reinforcement (hooks) to be parallel to each other on each bundle nor there is a need for them to be in contact.
Q) Will alternate drilling be imposed on this project?
A) Bid in accordance with contract plans and specifications.
