Finished floor elevation should be 4-6 inches above natural grade measured at the front entrance of the floor. Both the floor and the top of the vault should be above the surrounding ground level with the pathway sloped up to meet the entryway. Ideally, the back of the building should be slightly higher (up to but not exceeding 2% slope in any direction) to allow water to freely drain out of the toilet rooms.

3. The hole dug to accommodate the vaults must be large enough to be workable and to allow the floor to the building to fit on the vaults when placed, but small enough to avoid excessive backfill after placement.

B. Materials

1. Bedding material to be 3/8” minus crushed or screened aggregate.

3. Crane provided by contractor to off load precast concrete vault toilet from delivery truck and install all associated materials per requirements.

D. Excavation and Elevation

1. Comply with all applicable OSHA Standards for excavation.

2. Excavate for the installation of the toilet vault to a depth that will allow the structure site to be free draining after installation is completed. Allow for a 2” leveling course beneath the toilet vault. Stockpile topsoil in a separate pile at sites.

3. Finish floor elevation will be 4-6 inches above natural grade measured at the front (entrance) of the exterior slab unless otherwise approved by the customer.

Ideally, the back of the building should be slightly higher to allow water to freely drain out of the toilet rooms (up to but not exceeding 2% slope in any direction).

4. No excavation will be left open more than seven days unless otherwise approved by the COR.

5. All excavations left open overnight will be fenced with wire mesh or plastic mesh fence secured to steel posts all around the excavation.
