2. DESCRIPTION OF WORK

A. Building 350 Center Bay is an essential facility for CMXG. It houses the F-15

Canopy workload and the new Dowty Props workload. The four Air Handler Units (AHU) that supply the production bay are reaching the end of their expected lifespan and must be replaced. Currently three AHU’s (AHU-3, AHU-4, and AHU-5) have cooling only capabilities. One unit (AHU-2) provides heating capabilities with natural gas in addition to cooling. New AHU’s must be designed and installed to meet the temperature and humidity requirements for production and reduce delays resulting from frequent repair work and malfunctions of these units.

This project shall include all design and construction work necessary to replace the four AHU’s in like kind. The contractor shall create an appropriate phasing plan, remove the four AHU’s, remove any associated chilled water or natural gas piping that doesn’t meet new design criteria, and install new AHU’s, all associated piping, pipe insulation, pumps, strainers, valves, necessary ductwork, necessary electrical wire and breakers, and control systems, according to the design.

B. Design-Build Project Scope:

a) Project phasing is required to allow the government 24/7 access to the production facilities. Phasing plan shall entail beginning work on the north end of the building and working toward the south end. Evening and weekend access may be granted given sufficient cause and notice.

b) Site Investigations

1) The contractor is responsible for any site investigations necessary to fully comprehend the scope of the project.

c) Testing

1) Testing for asbestos as well as heavy metals such as lead, cadmium, chromium, etc. shall occur in the design phase to ensure adequate preparation for construction.

2) If evidence of heavy metals is detected, appropriate abatement plan will be included as part of the design for project phasing.

d) Demolish/Remove

1) Remove the four AHU’s.

2) Remove associated piping, insulation, pumps, valves, strainers, and gauges from the unit connection to the main line. Ductwork and controls that do not meet the new design criteria must also be removed.

3) All recycled materials will be turned in to the Government in provided dumpster/container.

e) Construct/Install/Repair/Replace/Relocate

1) Work with the Government to create a phasing plan that allows for continuous operation of the building.

2) Install new AHU’s with equivalent units in performance, function, and power requirements. Units shall meet 75°F cooling and 50% relative humidity for the summer months, and 70°F and 30-50% relative humidity during the winter months.

3) Install all new associated piping, insulation, pumps, valves, strainers, gauges, ductwork, and controls, in support of the project design and specifications.

4) Install controls for all new HVAC units.

5) Install four inch tall concrete platforms for each of the new AHU’s.

6) Provide temporary heating, cooling, and humidity control measures, as necessary, to maintain conditions in the building to support the work performed therein throughout all phases of the project.

f) Cost to include all site visits, site investigations and meetings with base personnel during design and construction of project. Contractor shall provide results of testing in written reports documenting existing conditions with drawings showing locations of existing utilities, photos of utilities found, a list of personnel and description of equipment used.

3. CONTINUED OCCUPANCY

A. Building 350 shall remain in full operation during the entire duration of the project.

The contractor will be given partial access to the project area.

B. The work area is not in a restricted area, but adjacent areas of the same building are secured areas, and will require permission and escort if any work is necessary in these areas to execute the project.

C. The Government reserves the right to take beneficial occupancy of parts of the project area before the total project completion date. This is not final acceptance, and identified deficiencies must still be corrected.

D. As stated above, the user/customer will need access to the building as required to maintain full production schedule, and the occupied Dock will be partially accessible for construction.

E. Give special consideration to construction phasing and impact on user activities, particularly if there will be utility outages and connection/reconnection of new and existing utilities.

4. DETAILED TECHNICAL CONSIDERATIONS

A. The design shall conform to the Robins AFB Base Facility Standards and Air Force Instruction (AFI) 32-1023, Design and Construction Standards and Execution of Facility Construction Projects.
