as follows: Construct embankments and/or cut existing grade to the top of caisson elevations before construction of the caissons. Provide vertical and tie reinforcement for the full height of the shaft. If the bottom of the caisson elevation is lower than required, then either provide additional vertical and tie reinforcement , at no additional cost to the Department, or suspend the reinforcement cage such that the reinforcement is in the proper position relative to the top of caisson elevation. Provide test holes and probe holes only as indicated. When permanent casing is used, drill, drive, or vibrate casing so soil is in full contact with the outside of the casing. Alternatively, place casing in an oversized hole and grout the annular space between the permanent casing and the surrounding soil to establish lateral support. Grout after the concrete has obtained its initial set but no later than 24 hours after placement of the concrete. Where excavation is stable and not subject to rapid degradation, the 24- hour period may be extended to 72 hours, as allowed . Use a pressurized grouting method capable of completely filling the open area. Provide grout as specified in Section 1108. 03(f)1, except testing is not required. When temporary casing is used, remove casing as specified in Section 1006.3(i). If unexpected construction conditions require the casing to remain in place, perform grouting as specified for permanent casing to fill cavities surrounding the casing. Place caisson concrete within 24 hours of the completion of excavation and within 3 hours of final inspection of the drilled shaft. Where excavation is stable and not subject to rapid degradation, the 24 hour period may be extended to 72 hours, as allowed .
1001.3, and as follows: Construct embankments and/or cut existing grade to the top of footing elevations. Excavate and backfill foundation areas as specified i n Section 204.3; and compact using a mechanical tamper. If unsuitable foundation material is encountered, remove all unsuitable material at least 12 inches or as specified or directed below the bottom of sprea
