cylinders for each day's production of each strength of concrete produced. 3. Test strand for conformance with ASTM A416/A416M and furnish report to Resident Engineer. 4. Inspect piles to insure specification requirements for curing and finishes have been met. // 3.3 FOUNDATION CAISSONS: A. Concrete Testing: Test concrete including materials for concrete as required in Article, CONCRETE of this section, except make two test cylinders for each day's placement of concrete. B. Maintain a record of concrete used in each caisson. Compare records with calculated volumes. C. Inspect percussion hole in bottom of each caisson to determine that material is capable of supporting design load. D. Inspect sides and bottom of each caisson for compliance with contract documents. E. Submit a certified Record” for each caisson, recording “Caisson actual elevation at bottom of shaft; final center line location of top; variation of shaft from plumb; results of all tests performed; actual allowable bearing capacity of bottom; depth of socket into rock; levelness of bottom; seepage of water; still water level (if allowed to flood); variation of shaft (from dimensions shown); location and size of reinforcement, and evidence of seams, voids, or channels below the bottom. Verify the actual bearing capacity of the rock strata by the use of a calibrated penetrometer or other acceptable method. SPEC WRITER NOTE: Delete below if only rock bearing. Revise test requirements to suit project. Coordinate probe depth with hardpan layer thickness. Do not let the probe penetrate into the next soil strata below, especially if water bearing, sandy layer is below. F. Caissons Bearing on Hardpan: Take undisturbed samples, suitable for tests required, from caisson bottom. Make auger probe to a depth of 2.5 meters (8 feet) below bottom and visually inspect and classify soil. Verify continuity of strata and thickness. 1. Conduct the following test on each sample, and report results and evaluations to the Resident Engineer: a. Unconfined Compression Test (ASTM b. Moisture Content (ASTM
