1.3 QUALITY ASSURANCE

A.

Manufacturer’s Qualifications: With submittal of bid documents, Contractor shall submit documentation regarding the manufacture of the units. Provide evidence that manufacturer has a minimum of three years experience with pre-casting units of similar type, and provide evidence that the manufacturer plant(s) used are certified by the National Precast Concrete Association (NPCA).

B.

Precast concrete manufacturer shall provide a licensed Structural Engineer to certify that the units conform to specified requirements.

C. Installation Qualifications: Regularly engaged for at least three years in installation of pre-cast concrete similar to this project.

D. Fabricate crypts to the interior dimensions described below. Replace or repair units that do not comply with the individual dimensions and tolerances.

E. Prior to or in the initial stage of crypt production, furnish at the site two perimeter crypts, a single interior crypt, and the proposed shelf removal tool to demonstrate quality of construction of crypts and conduct on-site buried crypt load testing to include removal and replacement of the inside shelf. Commence production of crypts only after submittal approval and on-site load testing has been scheduled for witnessing by the NCA Crypt Specialist.

F. Functional Load Test: A functional on-site load test will be made at the Contractor’s expense to insure the units are capable of supporting loads stated. The functional test will consist of following loading conditions:

1. Confined Loading: An interior unit between two perimeter units shall be placed in a hole dug in the ground on site and covered with 24 inches of soil or covered to the maximum depth as shown on the plans, whichever is greater. The soil will be compacted to Standard Proctor (AASHTO T-99) density along the sides of 95% and reduced density over the lid, both as shown on the plans. An axle load of 12,000 lbs. will then be passed over the covered crypts for a minimum of 10 times in repetition, in a manner that causes maximum lateral pressure due to wheel load on the sides of the crypts. The crypts shall then be fully excavated, exposed and the lids removed to allow careful examination inside and outside. The crypts must not show any signs of stress or cracking.

2. Concurrent with Confined Loading, the inside shelf of the interior crypt shall be loaded with one worker with a minimum weight of 200 lbs. Worker shall walk on individual supports to confirm structural integrity and load bearing capability. Worker shall adhere to all safety regulations while performing test. Upon completion of shelf load testing, and without entering the crypt and by one man, the inside shelf shall be removed by the removal tool, inspected, and lowered back into the crypt in the 2nd interment position. The inside shelf must not show any signs of stress, cracking or deflection.

1.4 DESIGN CRITERIA

A. Design Criteria (Double Depth Crypt):

Provide tool(s) that one man can easily retrieve and install the shelf from ground level without entering the crypt and demonstrate said tool at the crypt buried load testing.

6. The concrete lid shall be beveled along the entire top perimeter. Chamfer top edge of lid with a 1:1 chamfer beginning ½ inch down from top.

7. The design of casket risers shall allow the casket to rest ¾ inch above the inside floor of the crypt and above the top of the inside shelf in order to aid in casket lowering straps removal. In addition, rests location shall not exceed 21 inches from crypt centerline.

8. The crypt outside lifting wire shall be designed for transport and installation along with provisions for removal/abandonment of crypt lifting wire once crypt has been installed.
