SP00921 (2015 Specifications: 11-19-15) (This Section requires SP02001)
-
(Follow all instructions. If there are no instructions above a subsection, paragraph, sentence, or bullet, then include them in the project. The specifications may be modified to include project specific specifications, but all additions, deletions, or modifications must be sent to the ODOT Technical Resource and Senior Specifications Engineer for review and approval.)
Comply with Section 00921 of the Standard Specifications modified as follows:
(Use the following subsection .40(a) when the foundation will be embedded in rock or there is another reason to have additional reinforcing cage length. Check with designer.)
00921.40(a) Drilled Shaft Installation Plan - Replace the bullet that begins "Unstamped reinforcing steel shop drawings…" with the following bullet:
Unstamped reinforcing steel shop drawings and details of reinforcement placement, including bracing, splicing, centering, lifting methods, and the method for supporting the reinforcement on the bottom of the shaft excavation according to 00150.35. Include details on the type, number, and placement of spacers and other devices for ensuring the reinforcing cage position is maintained during construction. Include details for attaching the CSL test access tubes to the reinforcing cage (if applicable).
(Use the following subsection .45(a) when the foundation will be embedded in rock or there is another reason to have additional reinforcing cage length. Check with designer.)
00921.45(a) Placement - Replace the paragraph that begins "In each shaft, place…" with the following paragraph:
In each shaft, place reinforcing steel extending from 6 inches above the bottom of the shaft excavation to the elevation shown. The reinforcing cage may be supported on the bottom of the shaft excavation if approved. Support the reinforcing cage to prevent distortion or settlement during concrete placement. Support the reinforcing cage such that the supporting mechanism does not obstruct the center of the shaft and allows concrete placement vertically down the center of the shaft. If concrete placement does not immediately follow cage placement, remove the reinforcing cage from the excavation and rectify the integrity of the excavation prior to reinstallation of the cage.
Add the following paragraph to the end of this subsection:
To accommodate variations in shaft length, furnish steel reinforcing bar cages, including CSL access tubes if specified, 4 feet longer than the lengths shown. Add the increased length to the bottom of the cage. Following bottom cleanliness approval, trim the bottom of the steel reinforcing bar cage to the proper length prior to placing it in the excavation. Shift or trim CSL access tubes (if present) to the revised cage length. If CSL tubes are cut, adapt the ends of the tubes to receive the watertight caps as specified.
