TRENCHING

Bottom width:

No less than 12 inches or more than 24 inches wider than the outside diameter of the pipe.

Where a chain or wheel trencher is approved for use in a rural area, the trench width shall be 4 to 6 inches greater than the outside diameter of the pipe.

Depth: Provide minimum cover as specified, or depths shown on plans.

BEDDING

If existing soil cannot provide uniform, stable bearing support, over-excavate a minimum of 4 inches below bottom of pipe or structure and provide imported bedding material as directed by the Project Engineer.

If unsuitable soil is encountered a price for imported bedding material will be negotiated if not included in bid schedule.

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.

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.

Compact with a mechanical tamper to a density not less than 90% of the maximum dry density, determined by ASTM D698.

Backfill around septic tanks in 12-inch lifts.

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.

WARNING TAPE INSTALLATION

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

FROST PROTECTION

Place insulation in areas where water main, sewer service lines or water service lines cross a road, driveway, traveled path, or as indicated on the plans.

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

Grade fill so insulation lays flat.

Excavation, Trenching, and Backfill 02315 - 6

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.

Install 3 foot wide for pipes up to 6 inches in diameter and 4 feet wide for pipes up to 12 inches in diameter.

Extend insulation a minimum of 5 feet on each side of the road crossing.

Lap insulation by 6 inches or stagger by 6 inches if composed of two layers.

Minimum thickness for the first lift of backfill over the insulation is 8 inches.

Do not operate construction equipment directly on insulation. Do not compact first lift with backhoe-mounted compactor or any other large compaction equipment.

Compact remaining backfill using normal construction practices.

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.

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

Excavation, Trenching, and Backfill 02315 - 7

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

Water and sewer main crossing and parallel installation

Maintain a 10-foot horizontal separation (O.D. to O.D.) for parallel mains.

Upon approval by the Project Engineer, water and sewer mains may be installed closer than 10 feet, provided all of the following conditions;

a. Vertical separation is 18 inches (O.D. to O.D.)

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

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

DEFINITIONS

Solid Rock: Large masses of igneous, metamorphic, or sedimentary rock which, in the judgment of the Project Engineer, cannot be excavated without drilling, blasting, ripping equipment, or other specialized equipment not normally on the job site.

Loose Rock: Individual boulders and other detached stones having a volume of one cubic yard or more.

GENERAL

Inclusion of a bid item and estimated quantity for rock excavation in the bid schedule indicates that rock excavation is probable.

Exclusion of rock excavation from the bid schedule does not preclude the possibility that rock will be encountered; it indicates that rock excavation is not anticipated.

If unanticipated rock is encountered a price for rock excavation will be negotiated with the Contractor.
