Backfilling a. Furnish equipment, labor, and when necessary, suitable material to conform with Plans and Special Provisions required for backfilling the pipe line trenches according to Section 207, and as follows:
1) When testing for leaks in open trenches, do not backfill until testing is complete and leaks are eliminated.
2) When retaining pavement adjacent to trenches, replace removed pavement with the same or better material when approved in accordance with the appropriate Section for the pavement type replaced.
3) Place backfill on subgrades free of mud, frost, snow, or ice.
4) Place and compact bedding course on trench bottoms and where indicated. Shape the bedding course to provide continuous support for bells, joints, and barrels of pipes and for joints, fittings, and bodies of conduits/pipes.
5) Backfill shall include Class I or Class II Soils as defined in Section 810 or suitable material that conforms with the Plans and Special Provisions.
6) Backfill shall be placed in two stages: first, side fill to a height of 12 inches (300 mm) above the top of pipe; second, overfill to former surface grade. Side fill shall consist of granular material laid in 6-inch (150 mm) layers each consolidated by mechanical tamping and controlled addition of moisture, to a density of 95% as determined by the Standard Xxxxxxx test (AASHTO T-99 Method D) or GDT 67. Overfill shall be layered and consolidated to match the entrenched material in cohesion and compaction. The top 12 inches (300 mm) shall be compacted to 100% of specified density. Consolidation by saturation or ponding shall not be permitted.
7) Soil Moisture Control: Uniformly moisten and aerate subgrade and each subsequent fill or backfill soil layer before compaction to within 2% of optimum moisture content. Remove and replace, or scarify and air dry, otherwise satisfactory soil material that exceeds optimum moisture content by 2% and is too wet to compact to specified dry unit weight.
8) Initial backfill shall be carefully compacted under pipe haunches and evenly up on both sides and along the full length of piping or conduit to avoid damage or displacement of piping or conduit. Place and compact fill and backfill of satisfactory soil to final subgrade elevation. Backfill voids with satisfactory soil while removing shoring and bracing and/or trench boxes.
9) After backfilling, maintain temporary surface restoration per GA Standard No. 1401 until permanent repaving is complete. No separate payment shall be made for re...
Backfilling. The purpose of this section is to provide opportunities for employees to temporarily increase their number of hours of work, temporarily increase their wages, and/or acquire experience in a different job assignment.
4.11.1 When the District determines to fill a position held by an employee who is absent from work for a period of time known by the District to last sixty (60) working days or longer, the District shall post the temporarily vacant position promptly, but in no event later than ten (10) working days after the District has received notification and/or confirmation of the duration of absence.
4.11.2 The District will use the procedure outlined in “Promotion 4.4” in filling the temporary vacancy.
4.11.3 Any employee filling such temporary positions shall be returned to their regular position after the return of the employee on leave.
Backfilling. A. Support pipe and conduit during placement and compaction of bedding fill.
Backfilling. The following provisions shall apply to the backfilling of the Works:
Backfilling. The purpose of this section is to provided opportunities for employees to temporarily increase their number of hours of work, temporarily increase their wages and/or acquire experience in a different job assignment.
8.5.1 When the District determines to fill a position held by an employee who is temporarily absent from work for a period of time known by the District to last 30 working days or more, prior to seeking an outside applicant (substitute) the District shall post the temporary vacancy at all work sites for not less than six working days. During the posting period the District may fill the temporary vacancy at its discretion. The District shall select an existing District employee applicant to backfill if the Superintendent or his/her designee determines that the employee has a reasonable chance of succeeding in the position.
8.5.2 The following are exempt from the backfilling obligations described in 8.5 through 8.5.6 and may be filled at the District’s discretion: (a) any temporary vacancy created after the first backfilling of the initial temporary vacancy, and (b) absences anticipated to last less than 30 working days.
Backfilling. (i) Excavated material used as backfilling to excavations or completed structures shall be free from rubbish, vegetation, clods and lumps and shall be approved by the Engineer. The approved materials shall be placed in layers, not exceeding 225 mm in depth before compaction and shall be compacted to a dry density not less than ninety-five percent of the maximum dry density obtained by the test in Part VII of I.S. 2720 or to such higher density as is specified hereinafter. During compaction the backfill shall have a uniform moisture content equal to or a little above the optimum moisture content recorded in the I.S.
Backfilling. 1. Backfill for structures and trenches shall be as specified in "Embankments and Fills," this Section, with the following additional provisions:
Backfilling. Any trench or excavation made within any street, alley or other public way shall be backfilled in accordance with regulations prepared by the city engineer and approved by the board of public works. The board may hold a public hearing on the proposed regulations if it deems it necessary, and notice of such hearing shall be given as the board shall determine. Upon approval of the proposed regulations by the council and published, in the same manner as ordinances are approved and published, the regulations shall have the same force and effect as any other provision of this section and any violation thereof shall subject the permittee to the same penalty provided for in section 14-37 of this Code. The regulations may be changed or amended in the same manner.
Backfilling. Backfilling will not commence until a representative from the Public Works Department has performed an inspection. Any portion of the side sewer covered prior to inspection will be uncovered at the permit holder’s expense within two (2) days after notice to do so. Trenches will be carefully backfilled by tamping sand or other approved material to a depth of six (6) inches above the pipe to avoid damaging the pipe. All backfill material between the public sewer and the property line must be approved by the Director of Public Works, water- settled or mechanically tamped in six-inch layers to minimize settlement. Any settlement occurring within twelve months of backfilling will be corrected at the expense of the permit holder.
Backfilling. The plumbers shall properly backfill all excavation on water services so that there is no ditch left due to the settling of the earth.
