2. General Description:

Contractor must provide supervision, labor, material, and equipment required to perform all work for the following project: Building A-58 was constructed in 2009 as a residential type of facility used by the Child Youth Program as a group home for youth ages 6-18 years of age. (Norfolk 24/7 CDC) The original asphalt shingle roof and sheathing has sustained damage & deterioration over the years which has led to water intrusion into the building causing mold and water damage to existing finishes. Due to the visible mold in areas of the building, the facility has been deemed unsafe for children until the mold is completely remediated. This project will prepare construction documents for the replacement of the existing roofing system and mold remediation. Refer to section 7 “Project Overview and Work Requirements” for additional information.

All work must be performed in accordance with, but not limited to the following:

Standard industry practices.

Applicable local, state, federal codes, laws, and regulations.

The Unified Facilities Criteria.

3. Location:

The work is located at building A-58, Naval Station Norfolk, Virginia, approximately as indicated. The exact location will be shown by the Contracting Officer. Refer to attachment 8.1 Location map of Naval Station Norfolk – Building A-58.

1.5 QUALIFICATIONS

Furnish type of gypsum board work specialized by the installer with a minimum of 3 years of documented successful experience.

1.6 SCHEDULING

Shield air supply and distribution devices to prevent any uneven flow of air across the plastered surfaces. Provide ventilation to exhaust moist air to the outside during gypsum board application, set, and until gypsum board jointing is dry. In glazed areas, keep windows open top and bottom or side to side 3 to 4 inches. Reduce openings in cold weather to prevent freezing of joint compound when applied. For enclosed areas lacking natural ventilation, provide temporary mechanical means for ventilation.

In unglazed areas subjected to hot, dry winds or temperature differentials from day to night of 20 degrees F or more, screen openings with cheesecloth or similar materials. Avoid rapid drying.
