SUMMARY OF WORK

PART 1 - GENERAL

1.01 PROJECT DESCRIPTION

A. This project consists of removal and replacement of siding, insulation, building paper, flashing, and mudsill of one portion of a barracks. Remove and replace only the minimum amount of each of these items in order to access and replace the sill plate.

Work may also include addition of support to potentially compromised floor joists.

Install new T1-11 siding on the three walls identified as needing the mudsill replaced.

New T1-11 shall be painted to match the T1-11 siding on the rest of the building. Ensure that the space behind the T1-11 siding is furred out using a solid covering of tongue and groove lumber to match original siding or approved equal (See Detail C, Sheet 5 of the drawings). In order to replace the sill plate it is assumed that the building will be lifted using jacks and proper support. It is also assumed that the contractor will need to access the crawl space of the building. TECHNICAL PROPOSALS SHALL INCLUDE

DESCRIPTION OF METHOD(S) TO BE USED. There are, at a minimum, black widow spiders residing within the crawl space. It shall be the responsibility of the contractor to eliminate all pests prior to entering the crawl space. Pest abatement shall be completed in such a manner as to not cause an infestation of the barracks living space.

B. The project is located in Greenville, CA on a Forest Service Work Center within the Plumas

National Forest.

C. The work includes, scheduling, coordinating with government in order to accommodate barracks residents, shop drawings for temporary building supports, proper disconnection and reconnection of building utilities (including, but not limited to water supply (copper or PVC), cast iron drain, HVAC ducting, electrical supply and conduit, communication, copper LPG supply), carpentry, concrete, insulation and coordination of all sub-contractors and material suppliers. It shall be the responsibility to furnish all labor and supplies and to dispose of all excess and removed materials.
