STATEMENT OF WORK (SOW)

FOR

INSTALL STANDBY GENERATOR AND AUTOMATIC TRANSFER SWITCH

BLDG 1712

FAIRCHILD AFB, WA

9 February 2015

1. Scope of Work. This Statement of Work (SOW) defines the scope for this task order to include installation and connection of a standby generator and all associated components at building 1712, Fairchild AFB, WA. Work consists of providing a diesel, standby generator rated to provide full backup power for Building 1712, estimated to be 100 kilowatts at 800 amp service, complete with automatic transfer switch (ATS), all electrical connections, all-weather enclosure, and capacity/future connection for an uninterruptible power supply (to be provided by others). Work shall be in accordance with technical and regulatory requirements, and following instructions and recommendations of the manufacturer(s) and this Statement of Work (SOW).

2. General Work Description. This Statement of Work (SOW) defines the project as follows:

the contractor shall perform all demolition and construction activities listed below.

2.1. Design and provide generator and automatic transfer switch to meet full backup power requirement of Building 1712.

2.1.1. Generator shall be designed and sized to provide full backup power to entire facility as well as an uninterruptible power supply (UPS) planned to be installed at a future date (NOTE: UPS will only power rooms 145, 146, and 147, also known as the “Brain Stem”). The government estimates a minimum of a 100 kilowatt (kW) generator must be provided to meet all requirements.

2.1.2. Generator shall be diesel-engine powered three-phase output and include an automatic transfer switch specifically designed to meet the requirements of the generator and facility electrical infrastructure. Contractor shall provide and install all associated circuit and network boards required for safe and normal operation whether in test/load bank or emergency. Automatic transfer switch shall be designed and sized by contractor, but at a minimum shall be a four-pole switch to meet Fairchild AFB design and maintenance standards to include Service Entrance rated and Bypass Isolated..

2.1.3. Contractor shall connect the generator and all associated electrical components to the facility. Connections may be made directly at the transformer adjacent to the facility or routed to the primary distribution panels in the main electrical room of the facility. This determination shall be based on design and installation cost as well as maintenance and operation of the system, and part of the design-build process.

2.1.4. Generator must have capability of containing 400 gallons of fuel by an on board tank integrated into the all-season housing unit. Contractor will be responsible for test run fuel, government will be responsible for fueling tank.

2.1.5. Generator and all components must be installed in weather enclosures or in other approved standard installation to prevent system degradation by exposure to weather.

2.2. Contractor shall perform all site work to prepare generator placement, utility/duct and connections, and existing facilities/infrastructure modifications.

2.2.1. Site generator adjacent to existing facility and electrical infrastructure. In general, generator and accompanying equipment shall be located in the vicinity of the existing transformer and nearby electrical room on the north west corner of the facility. Siting shall be outside the training yard and not obstruct existing pedestrian or vehicular pathways.

2.2.2. Prepare site: remove any existing vegetation or other obstructions limiting placement of generator or infrastructure.

2.2.3. Prepare generator foundation: excavate generator placement site, place and compact gravel. Install utility duct bank/transmission lines as necessary for connection to facility/transformer, automatic transfer switch, future UPS, and day tank. Backfill and compact additional layers of gravel as required to prevent crushing by concrete or exposure.

2.2.4. Design and install longitudinal steel reinforcement as necessary to prevent tension failure of concrete foundation. Design, form and place Portland Cement Concrete foundation – concrete shall be capable of holding the compressive load of the generator, as well as live loads caused by generator vibration while operational. Concrete shall also be treated and placed in accordance with American Concrete Institute standard 318 and subparts to mitigate freeze-thaw cycle degradation and other location/weather hazards.

2.2.5. Contractor shall return site to previous condition (grass, rock, dirt backfill, etc.)

around concrete foundation and enclosure, as well as covering all duct work and utility runs, at completion of installation.

2.3. Contractor shall connect generator and associated equipment in accordance with National Electric Code and National Fire Protection Association provisions, as well as all applicable federal, state, and local regulations.

2.3.1. Connections shall be made at termination points – no splices or connections shall be made within conduit/duct between the generator and facility/other infrastructure.

2.3.2. All connections requiring a utility outage must be accomplished Friday, Saturday, Sunday, or Monday to prevent disruption of ongoing training operations.

2.3.3. Contractor shall perform all trenching, duct/conduit runs, and cable pulls necessary to connect generator, ATS, future UPS, and day tank.

2.3.4. Final connections must be tested and approved by Fairchild AFB Civil Engineering prior to covering work (Other tests and inspections may be stipulated by Fairchild AFB Civil Engineering at any time as well).

2.4. Contractor shall provide test run of generator for all foreseeable power loss scenarios including prime power shutdown (emergency/unplanned outage), planned utility shutdown, emergency bypass, and operating sequence in event of power “bump” or

“spike” scenarios. All performance will be inspected/reviewed by Fairchild AFB Civil Engineering.

3. Period of Performance. The performance period shall not exceed 150 calendar days. The performance periods shall be broken down into three phases. The contractor shall have up to 90 calendar days for completion of Phase I –Design and Material Submittals/Procurement; up to 30 calendar days for completion of Phase II - Physical Work; and up to 30 days for Phase III - Closeout. A Notice to Proceed (NTP) will be issued for each performance period.

Material submittal process must be complete and submittals approved prior to issuance of NTP and start of Phase II.

4. Hours of Operation. Normal hours of operation at the Resistance Training Lab are seven days per week, 0730 – 1600 hours.

4.1. Due to impact to student training and operations, contractor hours will be limited to

Friday through Monday, 0730 – 1600 unless otherwise coordinated with the Contracting Officer and end user.

4.2. All utility outages must occur on Friday or Monday, and be coordinated with 92d Civil Engineer Squadron no less than 10 business days in advance.
