Care shall be taken not to over-excavate. The bottom of the trenches shall be accurately graded to provide uniform bearing and support for each section of the pipe at every point along its entire length, except at bell holes and for the proper installation of joints.

Bell holes and depressions for joints shall be dug after the bedding has been graded. Bell holes and depressions shall be only of such length, depth, and width as required for properly making the particular type of joint. Stones shall be removed as necessary to avoid point bearing.

C. Except as hereinafter specified for wet or otherwise unstable material, over-depths shall be backfilled and compacted with select material.

Whenever wet or otherwise unstable material that is incapable of properly supporting the pipe is encountered in the bottom of the trench, such material shall be over-excavated to a depth to allow for construction of stable pipe bedding. The trench shall be backfilled and compacted to the proper grade with select materials.

1. Chilled Water and Heating Hot Water Lines: The width of the trench at and below the top of the pipe shall be such that the clear space between the barrel of the pipe and the trench wall is as shown on the plans. The width of the trench above that level shall be as wide as necessary for sheeting and bracing and the proper performance of the work. The bottom of the pipe shall rest firmly on bedding material for as nearly the full length of the barrel as proper jointing operations will permit.

2. Water Lines: San Bernardino County Water Standard Details and Specifications.

3. Gas Lines: Per the Standards and Agency Requirements of the California Corporation Commission (CCC) and the Owner.

4. Sanitary Sewer and Reclaimed Water Lines per San Bernardino County Regional Wastewater Reclamation Department Standard Details and Specifications.

3.9 BEDDING, SHADING AND BACKFILLING

A. Place bedding material as specified and as indicated on the plans, grade and compact material to the design grade. Excavate bell holes as required. The Contractor shall protect the installed bedding from damage due to construction operations and excess moisture. All bedding material, which is adversely damaged, shall be repaired by the Contractor to the satisfaction of the Engineer.

B. Coordinate shading operations with the requirements for insulation and pipeline testing. Shading material shall be deposited in 6-inch layers maximum and compacted with suitable tampers to the density as hereinafter specified until there is a cover of not less than 1 foot over the utility lines. The material in this portion of the trench shall be the type of material specified for the specific utility line and at a moisture content that will facilitate compaction. Take special care not to damage the coating, wrapping of pipes, and pipe insulation.

C. Backfill the remainder of trench, except for special materials for pavements, base course, etc. Backfill material shall be deposited in layers not exceeding 8 inches compacted thickness, and each layer shall be compacted to the minimum density specified as applicable to the particular area. Settling of granular, non-cohesive material with water shall not be permitted. Degree of compaction shall be expressed as a percentage of the maximum density obtained by the test procedure presented in ASTM D 698.
