This material shall be used as backfill for utilities, only if it is void of organic matter and other trash, and approved by the Contracting Officer.

PART 3 - EXECUTION:

3.1 EXCAVATION:

3.1.1 General: All excavation of every description and of whatever substances encountered shall be performed to the depths indicated or as required. During excavation, material suitable for backfilling shall be piled in an orderly manner a sufficient distance from the banks of the trench to avoid overloading and to prevent slides or cave-ins. All excavated materials not required or not suitable for backfill shall be removed and disposed of as indicated or as directed. Grading shall be done as may be necessary to prevent surface water from flowing into trenches or other excavations, and any water accumulating therein shall be removed by pumping or by other approved methods. Sheeting and shoring shall be done as may be necessary for the protection of the work and for the safety of personnel. Unless otherwise indicated, excavation shall be by open cut except that short sections of a trench may be tunneled if, in the opinion of the Contracting Officer, the pipe can be safely and properly installed and backfill can be properly tamped in such tunnel sections.

3.1.2 Trench excavation: Trenches shall be of the necessary width for proper laying of pipe and access. All trenching and excavation activities shall conform to the requirements set in 29 CFR 1926 subpart P, Excavations. The use of sloping and benching, or the use of shoring systems are acceptable methods to protect against trench cave-ins. Care shall be taken not to over excavate.

Except as hereinafter specified for wet or otherwise unstable material, over depths shall be backfilled as and with materials specified for backfilling the lower portion of trenches. Open trenches shall be kept free of standing water at all times. If dewatering of trench is necessary, contractor shall provide pumps to dewater, and he shall check with the contracting officer to determine where the water can be disposed. Most soils on Joint Base Elmendorf Richardson are previously disturbed and subject to vibrations from aircraft/roadway activity. These soils are considered Type B as defined in 29 CFR 1926 subpart P.

3.2 REMOVAL OF UTILITY LINES: When utility lines that are to be removed are encountered within the area of operations, the Contracting Officer shall be notified in ample time for the necessary measures to be taken to prevent interruption of the service.

3.3 BACKFILLING: The trenches shall not be backfilled until all required pressure tests are performed and the results are accepted by the Contracting Officer. Except as otherwise specified for special conditions of over depths, trenches shall be backfilled to the ground surface with

FA500021R0033

HJZH 17-1426 Install Electrical Drops selected material that is suitable for the specified compaction and as herein specified. Trenches improperly backfilled shall be reopened to the depth required for proper compaction, then refilled and compacted as specified. The ground surface shall be restored to its original condition and ground surface elevation as hereinafter specified.

3.3.1 Bedding materials in lower portion of trench: The sand bedding material shall be uniform throughout, material as recommended by the pipe manufacturer. As a minimum, the sand bedding material shall be non-frost susceptible and shall be well-graded non-angular sand with no material greater than 3/8" diameter. Sand backfill material shall be deposited in six-inch maximum thickness layers and compacted until there is a cover of not less than six (6) inches above the pipe.

3.3.2 Remainder of trench: The remainder of the trench shall be backfilled with material shown on the drawings that is free of stones larger than three inches diameter. Backfill material shall be deposited in layers not exceeding the thickness specified, and each layer shall be compacted to the minimum density specified as applicable to the particular area. Degree of compaction shall be as follows, expressed as a percentage of the maximum density obtained by the test procedure presented in ASTM D1557 (Modified Proctor Test):

3.3.2.1 Under pavements: Twelve inch layers, 95 percent maximum density.

3.3.2.2 Under turf or seeded lawn areas or open areas: 24 inch layers, 90 percent maximum density.

3.3.2.3 Under sidewalks, curbs and gutters, and gravel shoulders: One foot layers, 95 percent maximum density.

3.4 DETERMINATION OF DENSITY: Testing shall be the responsibility of the Contractor.

Testing shall be performed by an approved commercial testing laboratory at the expense of the Contractor. Tests shall be performed in sufficient number to insure that the specified density is being obtained; a minimum of one test every two hundred feet per lift is required under lawn and open areas, and at least one test every hundred feet per lift under roadways, sidewalks and other areas. Every road crossing shall be tested twice per lift. In addition, the Contracting Officer or his authorized representative reserve the right to require up to three additional tests per day at locations of his choosing at no additional cost to the Government. Laboratory tests for moisture-density relations shall be determined in accordance with ASTM D1557 (Modified Proctor). Determination of density shall be in conformity with the requirements of ASTM D2922 (Nuclear Method), ASTM D2167 (Rubber Balloon Method) or ASTM D1556 (Sand Cone Method). Copies of the test results shall be furnished to the Contracting Officer within 3 days of the performance of field tests. Failed tests must be re-accomplished at no additional cost to the Government.

3.5 EXCAVATED BACKFILL: Material excavated from lawn areas, open areas, and gravel shoulder areas shall be used as excavated backfill in these areas only and shall not be used under pavements, sidewalks, and curbs and gutters. Materials excavated from streets, sidewalks, and curbs and gutters shall be used as excavated backfill in these areas only.
