Mayo Observation Date: 10-31-2007 Item / Object Observed: D Slab DWall [] Grade Beam D Column D Paving D Other Specific Observation Location: L-8.5 to L-21, L-21 to 0-21, 0-21 to 0-22, 0-22 to S-22, 8-22 to 8-8.5 Referenced Drawing: Results: D Reinforcing steel placed in general accordance with the project drawings. o Exceptions noted and referred to contractor for correction. D Exceptions noted and referred to structural engineer. D Exceptions corrected prior to placement of concrete. Remarks: Pier S-14 is detailed to show 4 dowel bars with hooks. One of the hooked ends had been cut and removed. The superintendent was informed of the situation, and he decided to block off that area from concrete placement until a resolution was obtained from engineer-of-record.

(25 mm) of cracking through caps. 2 Well-formed cone on one end, vertical cracks running through caps. no well-defined cone on other end. 3 Columnar vertical cracking through both ends, no well-formed cones. 4 Diagonal fracture with no cracking through ends; tap with hammer to distinguish from Type 1. 5 Side fractures at top or bottom (occur commonly with unbonded caps). 6 Similar to Type 5, but end of cylinder is pointed. NOTES: . Compressive strengths determined in accordance with ASTM C39. . Cross-sectional area, diameter and length are standard unless otherwise noted. . Portions of the information contained in this report have been furnished by others. . Cylinders cured in laboratory in accordance with ASTM C31 unless otherwise noted. . Unbonded caps utilized in accordance with ASTM C1231 unless otherwise noted. Because of the violent release of energy stored in pads, the broken cylinder rarely exhibits conical fracture typical of capped cylinders and the sketches of types of fracture in Test Method C39 are not descriptive. . Samples taken in accordance with ASTM C172 where practicable. .
