C. Access to Site: N/A

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” 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. The customer may specify a finish floor elevation for buildings at some sites. The contractor will install buildings at these sites with the floor elevation within a plus or minus 0.05’ of the specified floor elevation.

4. No excavation will be left open more than seven (7) days unless otherwise approved by the customer.

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

6. The bottom of the fence will generally follow the contour of the ground.

7. Maximum spacing of the steel posts will be 10’.

8. Minimum height of the fence will be 36”.

E. Backfill and Compaction

1. Compact the natural ground at the bottom of the vault excavation with a minimum of three (3) passes with a whacker-type mechanical compactor or equivalent approved by the customer.

2. Install sand or aggregate bedding material for leveling course if needed. Compact leveling course with one (1) pass with a whacker-type mechanical tamper or equivalent approved by the customer. Grade leveling course so there will be no high spots in the middle of the vault bottom. Compact with a second pass with a whacker or approved equivalent tamper.

3. Set vault in place and check for level or appropriate scope. Backfill around structure. Use excavated material for backfill except those rocks larger than 6” in maximum dimension shall not be placed within 6” of the exterior vault walls.

4. Fill, adjacent to the building entry, will have excavated material placed in 8” loose lifts and compacted with a minimum of two (2) passes with a whacker-type mechanical compactor of equivalent approved by the customer.

F. Finish Grading

1. Spread excess excavated material from the vault around structure. Intended final grade is flush with the top of the front slab. Allow for placement of topsoil to reach that grade. Grade backfill away from structure at maximum slope of 5% unless otherwise approved by the customer.

Page | 24

2. Spread stockpiled topsoil as final layer after rough grading is completed. Areas disturbed by excavation, backfilling and stockpiling of excavated materials will be hand raked to remove exposed rocks over 1” in maximum dimension.
