PART 3 - EXECUTION

GENERAL

Trenching and excavation work shall be done in accordance with proper emphasis on safety as determined by the Contractor to conform to recommended safety standards such as OSHA 1910 and 1926.

A Competent Person, as defined by OSHA 1926, shall be on site at all times when excavation work is being completed.

Prevent movement of the pipe during placement of material.

Avoid contact between the pipe and mechanical compaction equipment.

Where a trencher is approved, backfill the trench from surface with selected material, free from large clods and all stones larger than 3 inches.

No frozen clods, saturated, foreign, or organic materials will be allowed.

Hand compact in 6-inch lifts from the bottom of the trench to 12 inches above the pipe crown.

Compact in a manner that will not produce undue strain on the tank.

Repair any trenches improperly backfilled or where settlement occurs, then refill and compact.

Restore surface to the required grade and compaction. Conform to Section 02300 for rough grading, finish grading and site surface drainage.

Remove and dispose of all surplus backfill materials to a location approved by the Project Engineer.

Center insulation over pipe or appurtenance with 1 foot of compacted fill between the pipe and the insulation.

Grade fill so insulation lays flat.

Insulate with a minimum of one 2-inch layer of polystyrene.

If a minimum bury depth is specified, install one 2-inch-thick layer for each foot of backfill less than the required minimum bury depth.
