Unauthorized over excavation shall be backfilled with acceptable bedding material at the Contractor’s expense.

HAUNCHING AND INITIAL BACKFILL

General.

Provide complete and uniform bearing and support for the pipe, including allowance for bell holes, or structure.

Excavation, Trenching, and Backfill 02315 - 4

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 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.

BACKFILL & COMPACTION

All buried material shall be inspected by technical representative prior to backfilling.

Backfill remainder of excavation with native material, free from large clods, stones 8 inches or larger, organic material or frost chunks.

All backfill shall be compacted in the specified lifts utilizing mechanical equipment designed for compaction. Compaction methods utilizing mechanical equipment not designed for compaction will not be approved.

All methods of compaction shall be approved prior to construction.

Compact in 6-inch lifts to a density not less than the density of the surrounding undisturbed soil or not less than 90% of the maximum dry density, determined by

ASTM D698.

In cases where the Contractor performs unacceptable methods of compaction, the work on the project will cease until an acceptable method of compaction has been approved. The Owner has the right to delay work until soil samples along the project alignment are taken for the purpose of developing a proctor for testing the compaction of the soil backfilled in the trench.

Conform to Section 02705 for backfill requirements within roadways.

Compact with mechanical tamper, after initial backfill, to a density not less than

95% of the maximum dry density, determined by ASTM D698 for the entire depth of the trench through a roadway or driveway.

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 Owner.

WARNING TAPE INSTALLATION

Install warning tape over water, sewer or force mains and service lines in trench 2 feet below finished grade.

Excavation, Trenching, and Backfill 02315 - 5

REMOVAL OF NUISANCE WATER

Remove nuisance water entering the trenches.

Nuisance water that can be removed through the use of sump or trash pumps is not considered dewatering.

Keep trenches free from water until waterlines, fittings, valves, sewer lines, manholes and other appurtenances are in place and sealed against the entrance of water.

Prevent all water, earth or any foreign material from entering any facility.

Keep trenches free from water until the facilities are in place, sealed against the entrance of water, and backfill has been placed and compacted above the water level.

LOCATE EXISTING UTILITIES

Field locate all existing underground utilities.

Utilize state “811” or “one-call” hotlines.

Contact all other utility owners not covered by the state “one-call” hotlines.

UTILITY CONFLICTS

Protect existing utilities from damage during excavation and backfilling operations.

Provide temporary support for existing water, gas, telephone, power, or other utility services that cross the trench until backfilling of trench is complete

Compact backfill to 95% of Standard Proctor Density under disturbed utilities.

Repair or replace any damaged existing utilities, at no additional cost to the project.

Water and sewer main crossing and parallel installation

Maintain a 15 foot horizontal separation (O.D. to O.D.) for parallel mains.

Upon approval by the Owner, water and sewer mains may be installed closer than

15 feet, provided all of the following conditions:

a. Vertical separation is 24 inches (O.D. to O.D.)

b. Water main is above the sewer main.

c. Separate trenches are maintained.

Maintain a minimum 24-inch vertical separation (O.D. to O.D.) for crossing mains with the water main above the sewer main.

a. Lay pipe with joints equidistant from the point of crossing.

If it is impossible to meet any of the above separation distances and deviations, one of the following methods shall be adhered to:

Excavation, Trenching, and Backfill 02315 - 6

a. Sewer main shall be constructed to water main pressure pipe standards meeting a minimum pressure class of 150-psi.

b. Either the water main or the sewer main may be encased in a watertight carrier pipe that extends 10 feet on both sides of the crossing. The carrier pipe shall be of materials approved by the regulatory agency for use in water main construction.

c. The water main installed shall be made of high density polyethylene (HDPE) pipe to eliminate the joints and possibility of leaks. Water mains shall be pressure tested in accordance to Section 02510.

Water and sewer service crossing and parallel installation.

Maintain a 30-inch horizontal separation from water and sewer services.

Maintain a 12-inch vertical separation for crossing water and sewer services.

Water service line splices or joints will not be permitted within 10 feet of a sewer line crossing.

MOVING FENCES AND MINOR STRUCTURES

Remove and reset culverts, drainage pipes or other minor structures that fall within the alignment of the new construction, to their original location and grade.

Visit the project site and determine actual conditions with regard to the existence of old car bodies, abandoned houses, fences, driveways, trees, stumps, brush, sidewalks, approaches, and other miscellaneous obstacles to construction.

Unless specifically referenced in a bid item, no separate payment will be made for the removal or replacement of these items.
