About this detail

Conduits are located within the middle third of the slab depth, maintaining a minimum conduit diameter spacing and a maximum of two crossing layers. One to two conduits are spaced with a minimum one-foot clearance, while groups of three or more conduits require additional number four reinforcing bars at twelve inches top and bottom. Specific notes mandate that conduits remain at least four feet away from column faces or stud rails, two feet away from post-tensioned tendon anchorages, and maintain specified horizontal and vertical clearances from post-tensioned tendons.

1' - 0" MIN 2" NOTES: 1. DO NOT PLACE CONDUIT WITHIN 4'-0" OF COLUMN FACE OR THROUGH SLAB SHEAR REINFORCING STUD RAILS. 2. KEEP CONDUIT AT LEAST 2'-0" AWAY FROM POST-TENSIONED TENDON ANCHORAGE . 3. MAINTAIN A MINIMUM HORIZONTAL CLEARANCE FROM PARALLEL PT TENDONS OF 1'-0" AND A MINIMUM VERTICAL CLEARANCE OF ONE INCH FROM PT TENDONS BEING CROSSED. 4. CONGESTED AREAS OF CONDUIT THAT DO NOT MEET THIS CRITERIA SHALL BE SUBMITTED TO THE ENGINEER FOR REVIEW. ADDITIONAL REINFORCEMENT MAY BE NECESSARY. 5. DO NOT TIE CONDUIT DIRECTLY TO REINFORCEMENT PARALLEL TO CONDUIT. PROVIDE MINIMUM db, BUT NOT LESS THAN ONE INCH CLEAR BETWEEN CONDUIT AND REINFORCEMENT. 6. HORIZONTAL OR VERTICAL CONDUIT SHALL NOT BE PLACED IN CONCRETE COLUMNS OR WALLS WITHOUT PRIOR APPROVAL OF STRUCTURAL ENGINEER.
