(Ord. of 3-1-2005(02), app. E, § 2.04)

(a)

When necessary to protect structures, paving or facilities, the sides of all excavations shall be sufficiently sheeted, shored and braced whenever necessary to prevent slides, cave-ins, settlement or movement of the banks and to maintain the excavation clear of obstructions that will, in any way, hinder or delay the progress of the work or endanger workers. Wood or steel sheet piling of ample design and type shall be used when necessary. All sheeting, shoring and bracing shall have sufficient strength and rigidity to withstand the pressures exerted and to maintain the walls of the excavation properly in place and protect all persons and property from injury or damage.

(b)

Where excavations are made adjacent to existing buildings or other structures or in paved streets or alleys, the contractor shall take particular care to sheet, shore and brace the sides of the excavation adequately so as to prevent any undermining of or settlement beneath such structures or pavement. The contractor will be liable for any damage to any structure or any injury to any person that results from his operations.

(c)

Sheeting and shoring materials shall be withdrawn as trenches are being backfilled, after backfill has been placed over pipe at least 18 inches. If their removal before backfill is complete endangers any adjacent structure, they shall be left in place until backfill is complete and pulled then, if possible. Voids caused by sheeting withdrawals shall be backfilled and tamped with thin rammers designed for the purpose. If not withdrawn, sheeting shall be cut off at least 18 inches below surface.

(d)

Sheeting, shoring and bracing shall be considered as an integral part of the excavation work and no specific payment will be allowed therefor.

(Ord. of 3-1-2005(02), app. E, § 2.05)

(a)

Where the excavation area shown on the plans falls under the groundwater surface or near the banks of a flowing stream or other body of water, the contractor may adopt and carry out any method he may deem feasible for the performance of the excavation work and for the protection of the work thereafter, provided the method and equipment to be used result in completed work which complies with the specifications and is acceptable to the engineer. In such cases, the excavation area shall be effectively protected from damage during the excavation period and until all contemplated construction work therein has been completed. Underwater excavation shall be in accord with the current United States Corps of Engineers National Permit for water line crossing of waterways.

(b)

The cost of all temporary construction work necessary or incidental to work under water or in wet conditions, including the cost of installing and removing sand bags, coffer dams, sheet piling, excavation and backfill, pumping and dewatering, shall be considered as an integral part of the cost of excavation, and no separate payment therefor shall be allowed or made.

(Ord. of 3-1-2005(02), app. E, § 2.07)

(a)

Excavation for structures shall be sufficiently large for the proper placing of forms and concrete and for dewatering purposes but shall not be excessively large in horizontal area. Banks may be sloped at a safe angle provided that such excavation does not endanger or damage existing or proposed structures, pipelines, etc. The bottom of the excavation shall be true to the required shape and elevations shown on the plans. No earth backfilling will be permitted under structures unless specifically shown on the plans. Should the contractor excavate below the elevations shown or specified, he shall fill the void thus made with thoroughly compacted, dense graded, crushed stone, with aggregate (sand cushion) acceptable to the engineer, or with class C concrete at no additional cost to the owner.

(b)

When muck, quicksand, soft clay, or other materials unsuitable for foundations are encountered extending beyond the limits of the excavation, such materials shall be removed and replaced with thoroughly compacted, dense graded, crushed stone, with aggregate (sand cushion) acceptable to the engineer, or with class C concrete.

(c)

In all cases where materials are deposited along open excavation, they shall be placed so that, in the event of rain, no damage will result to the work or adjacent property.

(Ord. of 3-1-2005(02), app. E, § 2.08)

(a)

The backfilling of pipeline trenches shall be started immediately after the pipe work has been inspected and approved by the engineer. Backfill material shall consist of fine loose earth free of large clods, stones, vegetable matter, debris, and/or other objectionable material. Backfill shall be carefully deposited in six-inch layers (before compaction) on each side of the pipe and then thoroughly and carefully tamped or rammed around the pipe with approved power tools until enough material has been placed and compacted to provide a cover of not less than one foot over the top of the pipe. If the trench extends along or across streets, roadways, proposed roadways, usable alleys or sidewalks, the remainder of the trench shall be backfilled and tamped to its full depth in the manner specified above with a minimum density of 95 percent standard proctor for the full depth. Otherwise, it may be filled with loose material without compaction. Where tamping of material is not required for the full depth of the trench, this material (from a height of one foot above the pipe upward) shall be as hereinbefore specified, except that a broken stone content of not more than 50 percent by volume will be allowed of stones not exceeding six-inch maximum dimensions, provided that these stones are thoroughly mixed with earth.

(b)

Before being placed under pavement, earth material for backfill which is, in the opinion of the engineer, too dry to allow thorough compaction, shall receive an admix of sufficient water prior to compaction to insure such compaction. Earth material considered by the engineer to have excessive water content shall not be placed.

(c)

Backfill material having less than a ten percent clay content may be compacted by puddling with water in lieu of tamping when authorized by the engineer. Such puddling shall consist of applying water under pressure to the entire content of the trench beginning near the trench bottom and working through pipes or well points.

(d)

Backfill materials used shall contain a sufficient amount of moisture for proper compaction. In areas to be paved and areas not to be paved but inside road rights-of-way, the backfill shall be brought up in accordance with section 30-300(a) and compacted to not less than 95 percent of standard proctor.

(e)

Compaction tests will be required at varying depths and intervals determined by the engineer. Tests shall be made by a qualified independent testing laboratory selected by the engineer. The owner shall pay for all compaction testing. However, in the event that such tests fail to meet the requirements of the specifications, the expense of such tests shall be borne by the contractor.

(f)

Where the test results indicate that compaction is less than the allowable minimum specified in section 30-300(a), the material will be removed to the depths and limits determined by the engineer and new material placed and compacted to minimum standards at no additional cost to the owner.

(g)

Where excavation has been made within the limits of easements across private property, the top one foot of backfill material shall consist of fine loose earth free of large clods, vegetable matter, debris, stone and/or other objectionable materials.

(h)

Where tamping of backfill material is not required for the full depth, the backfill material shall be neatly rounded over the trench to a sufficient height to allow for settlement to grade after consolidation. Any deficiency in the quantity of materials for backfilling the trenches or for filling the depressions caused by settlement shall be supplied by the contractor.

(i)

Where pipe trenches are cut across pavement, the contractor shall construct a temporary surface over the cut by filling and tamping the upper six inches of the cut with selected gravel or crushed stone which will not disintegrate under the traffic and which shall be maintained in good condition under traffic until the permanent pavement has been constructed. No specific payment will be allowed for temporary surfacing.

(j)

All backfilling shall be done in a manner which will not disturb or injure the pipe or structure over or against which it is being placed. Any pipe or structure injured, damaged or moved from its proper alignment during backfilling operations shall be opened up and then rebackfilled as herein specified.

(k)

The contractor shall replace all surface materials and shall restore drives, curbing, sidewalks, gutters, shrubbery, fences, sod, and other disturbed surfaces to a condition equal to that before the work began, furnishing all labor and materials incidental thereto. No payment for such items shall be made unless specifically stated in these specifications and or in the bid schedule.

(Ord. of 3-1-2005(02), app. E, § 2.09)
