2. The Contractor is responsible for the security or the Contractor’s equipment and materials.

3. Utilities are not available at the site for construction purposes. The Contractor will be responsible for coordinating the installation of temporary power for the site and the cost for the service.

4. No fuel storage on site is permitted. Fuel trucks must be equipped with spill containment kits and portable berms that meet all state and federal regulations. A spill containment plan must be submitted and approved prior to construction.

5. The Contractor shall provide temporary toilet facilities (porta-potty) at the site during all construction work. Toilet facilities shall be provided at a rate of one stool for every 10 workers assigned or working on site. Contract may use the existing toilets located throughout the campground in lieu of temporary toilet facilities until these toilets are removed.

6. All construction equipment shall be pressure washed before entering the Site.

SEEDING 329206-4

received seeding shall be approved by the Contracting Officer (with assistance from the Forest Service ecologist or botanist) prior to beginning seeding.

3.2 PREPARATION OF SEEDING AREA

C. Contouring of soil shall occur with on-site materials.

D. Just prior to seed application, slopes shall be scarified.

3.3 SCATTERING ORGANIC MATERAIL

A. Branches and dead and down materials shall be scattered throughout exposed soil areas to provide a source of organic matter, erosion control, and seed catchment. Enough organic matter shall be scattered to provide light shading to the soil; sunlight shall reach mineral soil. Organic materials up to 6” diameter shall be used. Branches and dead and down materials shall be taken from clearing and grubbing activities. The Contracting Officer (with assistance from a Forest Service ecologist or botanist) must be on-site to assist in determining the amount of organic material scattered throughout the seeding areas.

3. Compaction and Testing: Backfill in trenches under roadways and parking areas shall be maintained, wetted, or dried to optimum moisture for maximum compaction, placed in the trench in horizontal layers not to exceed 6 inches in thickness (loose measurement), and compacted to not less than 95 percent of maximum dry unit weight, as determined by AASHTO T180, Method D, of ASTM D 698, Method D. Ascertain adequate compaction during the backfill operation by performing in-place density tests in accordance with one or more of the following standard test procedures: ASTM D 1556, D 2167, or D 2922, or AASHTO T 191, or T 310.

E. Special Bedding – Imported

1. Special bedding shall be placed, as directed by the Contracting Officer, in trenches, as necessary, to provide a minimum of 4 inches firm bedding on which to set the pipe in areas where relatively unstable conditions exist, due to seeping ground water or mud caused by ground water, or by water from any other source which cannot be diverted. After the material is placed in the trench, leveled, and consolidated, it shall be trimmed to proper sub grade and shaped to receive the pipe.

2. The Contractor shall construct restrictive sections (dams) in the special bedding material at least every 200 feet to minimize the possibility of excessive ground water flows undercutting the pipe. The dam shall extend across the entire width of the trench, be a minimum of 3 feet long, and shall extend to the top of the pipe zone material.

F. Imported Material

1. Any trench excavated material that can be transported less than 300 feet to other areas along the trench and used, in accordance with specifications, shall not be considered as imported material. When the Contractor is required to import material, it shall be from a designated or approved source.

G. Trenches in Embankments

1. When pipelines are to be placed in trenches excavated in embankments, the excavation of each trench shall be performed after the embankment has been constructed to an elevation at least 3 feet over the pipe or to finish grade, whichever is least.

H. Surface Restoration in Areas Other Than Roads

1. All surfaces shall be restored to the required grade (usually original ground line), mounded over or smoothed off as directed, and left in a uniform and neat condition, to the satisfaction of the Contracting Officer. Surface drainage shall be diverted so that it will not flow along a trench. In areas where natural revegetation is designated (no planting to be done), the Contractor shall scarify all disturbed or compacted areas and right-of-ways such that the surface of the ground is loose to a depth of at least one inch. In areas to be seeded, the area shall be prepared in accordance with Section 329206 “Seeding.”
