This is a “Design-Build” project to repair Booster 3 Station (Bldg-680, Bldg-681, and Bldg-682A), Generator House (Bldg-683) and Water Treatment Station (Bldg-6856). Work will include renovations to Buildings 680, 681, 682A and 6856, replacement of circuit breaker and wires at Bldg-683, replacement of water treatment system at B6856, installation of new piping system, booster pumps, variable frequency drives and SCADA system, new painting and coating for walls, roof, and floor, installation of manual hoist system for each building, new aluminum door and rollup doors, provide new wires, conduit, and lighting fixtures.

1.2 EXISTING OPERATIONS:

The construction work activities will be coordinated with the facility manager and building occupants.

Contractor shall coordinate all interruption of utility services. All other actions not involving interruption of services can be conducted during regular working hours. In the event work/project activities other than what is indicated in this project program occur simultaneously, the contractor shall verify, coordinate, and may be required to phase such work/project activities.

1.3 LOCATION OF WORK:

The project is located at Booster 3 Station (Bldg-680, Bldg-681 and Bldg-682A), Generator House (Bldg-683) and Water Treatment Facility (Bldg-6856), Andersen Air Force Base (AFB) Guam. See attached site map.

2. PROJECT OBJECTIVES:

2.1 SCOPE OF WORK:

The contractor shall provide all labor, materials, equipment, permit and clearances, architectural and engineering services, transportation, supervision, and other incidental work required for the project. Other incidental work required includes all items and considerations necessary to ensure a complete and usable final product, including, but not limited to, the necessary design and construction considerations not specifically stated elsewhere in this statement of work. Complete and usable final product means that the completed final product is finished throughout and can be used to fully satisfy the requirements and the intended purpose of the project.

Perform all work according to all local and Federal safety and health regulations. Comply with the current Occupational Safety and Health Administration (OSHA) regulatory requirements.

All unforeseen utilities and appurtenances affected by the construction shall be protected. Damage to existing utilities and appurtenances shall be restored to its original condition at no additional cost to the Government.

The attached notional sketch/drawing with dimensions shown may not be accurate and is only to be used as reference for location and layout purposes. All drawings and shop drawings shall be based on actual measurements, conditions and shall be developed to provide the least demolition and removal work possible.

Contractor shall be responsible for field verification to verify on site all dimensions, elevations, utilities, power
