A. Summary. “Replace Emergency Generator, B213” is a Design-Build contract at Pittsburgh ARS, PA. This work consists of performing all design and construction work which includes providing all materials, labor, and equipment necessary to provide a useful, operable, and serviceable generator in accordance with this statement of work.

B. Repair Work. Replace existing 100 kW natural gas generator with new appropriately sized diesel powered backup generator at dining facility, B213.

C. Site Plans. Attached are drawings that show the current layout of the work area associated with this project.

II. PERFORMANCE TIME: Work is to be completed within 180 calendar days after NTP is approved, during normal duty hours from 0730 to 1600, and weekdays Monday through Friday, with no work on federal holidays. Any deviations from the normal working hours must be approved 72 hours in advance by the Contracting Officer. Typically work will not be allowed during training weekends, usually the first weekend of the month.

III. DESIGN

A. Architect/Engineer. The Contractor will provide design by retaining an Architect/Engineer (A/E) who will complete design documents in accordance with the phases and schedule stated herein. The design shall include work of all trades required to result in a complete and functional project, ready for use.

The generator design shall be based on A-E review, investigation, and measurement of actual project conditions and shall not rely solely on as-built or other generator drawings provided by the Government.

The design must include the following considerations:

1. Disconnect and remove the existing 100KW natural gas generator, drain and properly dispose of fluids, and turn the generator over to the government.

2. Provide and install new appropriately sized diesel generator with fuel tank, based on existing load at 120/208V Main Distribution Panel.

3. Cap off existing natural gas piping.

4. Provide environmental protection for diesel storage tank.

5. Connect new generator to existing transfer switch and replace cables as necessary.

6. Install recording ammeters during a primary UTA weekend, as part of the data gathering necessary to properly size the generator.

7. Balance the load in the building on the 120/208 Volt service, and provide an up to date electric single line diagram.

8. With the 60% Design Submittal: Complete Lines 10-26 on the Generator Authorization and Design Approval Request form (attached) and provide panel schedules and genset sizing calculations. Include the one-line diagram and the results of the recording ammeter.

B. Documents

General. Design documents will be prepared by a current, Pennsylvania registered Architect or (as appropriate) Engineer. This includes all drawings, sketches, and the cover page of project manuals. Drawings for electrical must be stamped by a registered professional engineer. The A- E shall include design disciplines as follows:

1. Architectural

2. Plumbing

3. Electrical

4. Initial investigation: The A/E shall spend a minimum of 16 hours on site (exclusive of travel time) to review existing equipment, utilities, structural issues, client operations, client requests, and scenario development. Verify conditions and dimensions of existing generator installation. If necessary remove existing construction to expose concealed elements or systems requiring verification. Patch exploratory areas to maintain integrity, weather-tightness, and safety of building/generator.

5. All work performed is to conform to the latest edition of the International Building Code, National Electric Safety Code, OSHA and all other applicable codes. All design will be in accordance with any referenced Air Force Instructions, EPA and PA DEP Regulations, International Building Code, PA Dept of L & I, the National Electric and Plumbing Codes, NFPA Codes, and applicable industry standards such as ASHRAE and ASME.

6. Design shall comply with AFI 32-1062, Electrical Systems, Power Plants and Generators.
