The weather <br /> conditions were approximately 72°F and inside. Reinforcement was found to be in <br /> conformance with the approved structural drawings (S2.1, 1&4/S3.1). Concrete was placed via <br /> a boom pump, internally vibrated, and was hand-finished. The results of our inspections were <br /> discussed with the contractor prior to leaving the site. GeoTest will return upon request for <br /> further inspections. <br /> COPIES:brady@tigerconstruction.us,Todd@tigerconstruction.us Reviewed by <br /> This report shall not be reproduced except in full,without the written approval of GeoTest Services,Inc. <br /> The above test results relate to the sample(or location)tested. <br />
