STATEMENT OF WORK

CERC ACID HOOD DUCT REPLACEMENT

I. GENERAL INFORMATION

a. INTRODUCTION. The Department of the Interior (DOI), U.S. Geological Survey (USGS), Columbia Environmental Research Center (CERC) 4200 New Haven Road, Columbia, MO 65202 has a requirement for the modification of exhaust ducts and to disassemble and unhook the exhaust blower fans and assembly and move to a different area for both the A-3 main building and C-3 building acid hoods.

b. BACKGROUND. The Columbia Environmental Research Center (CERC) conducts research needed to address national and international environmental contaminant issues and effects of habitat alterations on aquatic and terrestrial ecosystems. The A3 Main Building at the CERC is a 34,019 square foot research laboratory building that houses several research laboratories, office space, and a 6,000 square foot research wet laboratory.

The center recently had two acid hoods installed in the facility's wet labs. Months after the install, the center noticed large amounts of corrosion fluid leaking out of the fume hood duct work on both acid fume hoods. The center had stainless duct work installed for one hood in the A-3 main building and the C-3 hood they left the original duck work. Both hoods have corrosion that is dripping down the hood.

c. DEFINITION/APPLICABLE DOCUMENTS. N/A.

d. SCOPE. The contractor shall provide all materials, labor, equipment, travel and supervision necessary to disconnect the fume hood exhaust stack at the top of the fume hood in the A-3 Main building wet-lab and remove and dispose of the existing duck work. The contractor shall disconnect the fume hood exhaust stack at the top of the fume hood in the C-3 building and remove and dispose of the existing duck work.

The contractor shall install new corrosion resistant exhaust duct (see below) from the acid fume hood output exhaust. The new duct shall route up and extend thought the closest window on the north side of the roof top in A-3 wet lab. The contractor shall remove the exhaust fan from the west side of the roof and reinstall it on the north end of the roof.

The contractor shall remove and replace the acid fume hood duct in the C-3 building.

II. WORK REQUIREMENTS

2. Disposal shall be in accordance with all local, state, and federal regulations.

ii. CONSTRUCTION.

1. Existing site conditions.

a. The existing fume hoods are located in laboratory room A-3 wet-lab and C-3 lab 06. Access is through a standard double door entryway. Access to the roof is available via an outdoor stairway located on the south side of the building.

b. Electrical. The load panel for the A-3 main building fume hood is P-1 breaker 17. The load panel for the C-3 building fume hood is panel 3 breaker 18.

2. The contractor shall disconnect the fume hood exhaust stack at the top of the fume hood in the A-3 Main building wet-lab and remove and dispose of the existing duck work. The contractor shall disconnect the fume hood exhaust stack at the top of the fume hood in the C-3 building and remove and dispose of the existing duck work.

3. The contractor shall install new corrosion resistant exhaust duct (see below) from the acid fume hood output exhaust. The new duct shall route up and extend thought the closest window on the north side of the roof top in A-3 wet lab.
