E. Perform cutting work of other trades only with consent of that trade. Cutting structural members not permitted without consent of the A/E.

3.4 INSTALLATION

A. Install Work as specified and in accordance with the Drawings and manufacturer's instructions. Where these conflict, manufacturer's instructions govern.

B. Review Architectural, Mechanical and other applicable drawings and applicable Shop

Drawings to prevent switches, outlets, and other equipment from being hidden behind doors, cabinets, counters, heating equipment, and similar items, or from being located in whiteboards, tackboards, glass panels, and similar items.

F. Store excavated material (temporarily) near excavation in manner which will not interfere with or damage excavation or other work.

G. Retain excavated material which complies with requirements for backfill material.

Dispose of excavated material which is either in excess of quantity needed for backfilling or does not comply with requirements for backfill material. Remove unused material from project site and dispose of in lawful manner.

H. Backfill trenches only after observation by the A/E. Install backfill material under, around, and between conduit and sides of trench by hand, shovel tamped in place. Cover in 6 inch layers to 12 inch thickness over top of conduit or cabling. For final backfill, fill and tamp remainder of backfill material in 6 inch layers. Provide backfill materials as follows for buried conduit or cable (other than concrete encased):

1. Backfill below, on sides of, and over conduit or cable: Sand or pea gravel.

Minimum thickness of 6 inches above, below and at sides of outer conduits.

Minimum 3” spacing between conduits.

2. Backfill to within 6 inches of Final Grade: Soil material suitable for compacting to required densities. Per Division 31requirements.

3. Backfill for top 6 Inches of excavation: Top soil except where excavations occur below paved or gravel area provide compacted gravel backfill or surface area as indicated.

I. Compacting:

1. Perform compacting individually, for each 6 inch layer (maximum) loose thickness of initial and final backfill. Comply with ASTM D 1557. Where roadway or parking area surfaces will be placed over backfill, and to 10 feet beyond building perimeter, compacted to 95 percent of maximum density. Elsewhere, 90 percent. Test in accordance with Divisions 1 and 31.

PIERCE COUNTY

ANNEX EVSE SERVICE 260510 - 5 CD SET

2. Take special care in compacting under services where they enter building to prevent settling. Contractor fully responsible for damage to piping and property as a result of settling around service conduit and cabling.

J. Subsidence: Where subsidence is measurable or observable at electrical work excavations during project warranty period, remove surface (pavement, lawn or other finish), add backfill material, compact, and replace surface treatment. Restore appearance, quality, and condition of surface or finish to match adjacent work and eliminate evidence of restoration to greatest extent possible.

3.8 CONCRETE BASES

A. Unless noted otherwise, provide 4 inch high reinforced concrete bases for floor mounted and floor standing electrical equipment, including generators, transformers, switchgear, battery racks, motor control centers, and similar equipment. Extend bases 4 inches beyond equipment or mounting rails in each direction unless noted otherwise on the

Drawings.

B. Concrete bases shall be provided under Division 26. Coordinate size and location of bases and provide required anchor bolts, sleeves, and templates required to obtain proper installation.
