Excavation, Trenching, and Backfill 02315 - 4

HAUNCHING AND INITIAL BACKFILL

General.

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

Work material under and around the pipe to ensure full pipe support.

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.

Excavation, Trenching, and Backfill 02315 - 5

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.

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.

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

For parallel placements, sanitary sewer must be constructed with equivalent protection such as concrete encasement, vacuum sewers, or jointless pipe such as fused HDPE or cured-in-placed pipe liner

For crossing placements, sanitary sewer must be constructed of one of the following materials and pressure tested to assure water tightness:

a. Ductile iron pipe conforming to ASTM A536 or ANSI/AWWA C151/A21.51 with minimum thickness class 50 and gasketed, push-on or mechanical joints

Excavation, Trenching, and Backfill 02315 - 6 in conformance with ANSI/AWWA C110/A21.10 or ANSI/AWWA C111/A21.11.

Maintain a minimum 10 feet horizontal separation from water and sewer services as measured from edge to edge of the pipes.

a. Water main is above the sewer main.

b. Separate trenches are maintained.

Maintain a minimum 2 feet vertical separation for crossing water and sewer services.

a. If the sewer pipe is to be installed less than 2 feet below the water pipe, the sewer shall be encased in concrete with a minimum thickness of 6 inches for a 10-foot distance on each side of the crossing or the crossed section.

This requirement must also be followed where a water main must cross under an existing sewer main.

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.

Erosion and Sediment Control 02370 - 2

1.5 DEFINITIONS

A. Erosion Control: Any practice that protects the soil surface and minimizes the amount of soil particles detached and transported by rainfall or wind. Erosion control is implemented as a source control.

B. Sediment Control: Any practice that traps the soil particles after they have been detached and transported. Sediment control begins with erosion control by minimizing the potential sources of sediment. The emphasis should be placed on providing a protective cover on the soil surface, diverting runoff so that it does not flow across disturbed areas, and preserving existing vegetation to maximize soil infiltration and capture sediment.

1.6 QUALITY ASSURANCE

A. Erosion control materials, methods, and practices shall conform to the strictest of applicable state or Tribal agency handbooks of Best Management Practices, laws established for the purpose of erosion control, or the specifications herein.

1.7 CLEANUP

A. Remove sediment deposits in a timely manner when deposits reach 1/3 the height of the silt fence or bale line.

1. Place in the topsoil stockpile area or area approved by the Owner.

B. Remove temporary erosion and sediment control measures only after the area has stabilized and vegetation has developed to the extent that further erosion is unlikely.
