A. Cutting and Drilling: The Contractor shall be held responsible at all times for contents and structural conditions of the premises and building within the work area, and shall do or supervise all cutting, drilling, reinforcing, and patching required for work of all the Contractors and trades included in work of this Contract, and to do so in a timely manner to avoid any hindrance to work of others.

Cutting done by anyone other than the Contractor shall be approved by the COR. In such cases the Contractor shall supervise such cutting and shall not be relieved of responsibility for error or damage to related or adjoining work. Cutting and patching of specific items may be separately described under the various divisions of these specifications that do not, in any way, diminish the

Contractor's primary responsibility for all cutting and drilling.

B. Patching: Any cutting of finished surfaces occurring in the course of the work shall be patched and/or repaired to match the existing work in color, texture, alignment, and every other respect to the satisfaction of the COR. Materials shall be equal to or better than the pre-construction condition.

3. Excavate and shape trench bottoms to provide uniform bearing and support of pipes and conduit.

Shape subgrade to provide continuous support for bells, joints, and barrels of pipes and for joints, fittings, and bodies of conduits. Remove stones and sharp objects to avoid point loading. For pipes or conduit less than 6 inches (150 mm) in nominal diameter and flat- bottomed, multiple-duct conduit units, hand-excavate trench bottoms and support pipe and conduit on an undisturbed subgrade. For pipes and conduit 6 inches (150 mm) or larger in nominal diameter, shape bottom of trench to support bottom 90 degrees of pipe circumference. Fill depressions with tamped sand backfill.

02270-4

2. Construction Requirements

A. General: The COR has the authority to limit the surface area of erodible earth material exposed by trenching and excavation, and to direct the Contractor to provide immediate permanent and/or temporary erosion control measures to prevent contamination of adjacent drainage ditches, canals, or other areas of water impoundment. Such work should coincide with the Contractor’s Erosion Control

Plan. Cut slopes shall be seeded as the excavation proceeds. Under no circumstances shall grading be allowed to exceed the operating range of the grassing equipment In addition to minimizing erosion, this is necessary to keep attraction to birds, to a minimum. The Contractor shall incorporate all erosion control features into the Project at the earliest practicable time as outlined in his accepted Plan.

B. Erodible Area: The Contractor shall limit the area of excavation and trenching operations commensurate with the Contractor’s capability and progress in keeping the finish grading, seeding and other such erosion control measures current in accordance with the accepted Plan.

3. Protection During Suspension of Contract Time - In the event that it is necessary to suspend the construction operations for any appreciable length of time, the top of the earthwork shall be shaped in such a manner as to permit runoff of rainwater. The COR has the authority to apply temporary seeding or other erosion and sediment control measures to minimize erosion and sediment transport.
