D. Replacements and repairs be done at no additional cost to the Government. 3.7 BACKFILLING A. Prior to the backfill being placed between the crypts, a professional registered Land Surveyor shall: 1. Survey the in place crypts and provide a written certification that they are, within allowable tolerances installed: a. At the design locations b. Properly aligned c. At correct elevations and slopes B. The following documents shall be provided to the RE/COR: 1. An electronic drawing of the as-built conditions for the installed crypts. 2. A copy at appropriate scale so the crypt field is fully shown on a maximum sheet size of 600 mm x 900 mm (24” x 36”) with all indications of variances in the placement from the design drawings shown. 3. A written certification that during the manufacturing, handling, setting, and or crypt numbering process that each of the lifting bowls were operated using the designed lifting device, and that any excessive concrete debris has been removed to allow free operation of the lifting bowls. A description of when in the process each of the lifting bowls were used shall also be provided. C. When all of the crypts in a specific field are installed as indicated in the design drawings and details, and the surveyor has so certified, the RE/COR will approve the Contractor proceeding with the backfill between the crypts. The Contractor is responsible for insuring that the crypts do not move during the backfill operations, including but not limited to providing adequate blocking at the base of the units, if deemed necessary, to prevent them from moving during the backfill operations. D. Protect installed units during backfill operations. E. Install approved backfill against outside of all units, insuring no voids are remaining. Approved backfill shall: Contain no materials that will a concentrated point load. The perimeter wall backfill shall be compacted to Standard Proctor (AASHTO T-99) to 95% density to the level equal to the top of the crypts.
