Attachment 1 - SOW M320 ROCA TOWER and GIB V3.pdf

Statement of Work (SOW)

FWA Grenade Launcher Range M320 ROCA Buildings

1.0 Background

Fort Wainwright (FWA) home to the United States Army Alaska (USARAK) and the 11th Airborne Division which serves as a strategic power projection platform. Its mission requires infrastructure capable of withstanding the demanding sub-arctic environment to ensure operational readiness for worldwide deployment. This project will provide critical range facilities designed for durability and performance in these conditions.

2.0 Scope/Objective

This SOW outlines the build requirements for one (1) TWO-STORY Range Operations Center (ROC) Tower and one (1) 20’ x 40’ General Instruction Building (GIB) for the M320 Grenade Launcher Range located on the FWA Small Arms Complex. The objective is to deliver facilities engineered specifically for the sub-arctic climate of FWA, addressing challenges such as discontinuous permafrost, significant snow loads, and extreme temperature fluctuations.

Both Structure shall be fully equipped with electrical systems to include task lighting, emergency/exit lights, 120V electrical outlets, a red-light circuit for nighttime operation, and an underground service entry.

3.3 Fort Wainwright Range Complex Master Plan, Fort Wainwright Design Guides

4.0 Tasks

The Contractor shall provide all supervision, equipment, materials and labor to construct one (1) each ROC Tower and one (1) each General instruction Building on the FWA Small Arms Range Complex (Range Road, Fort Wainwright, Alaska 99703)

4.1 Construction of Range Operations Tower

General Requirement: The Contractor shall build one (1) two-story ROC Tower approximately 12’ x 12’ cabin (control room) with 18’ eave height. The second-floor control room shall be accessible via one (1) flight of stairs and feature a 4’ walk around mezzanine catwalk.

4.1.1 Foundation and Structural

Foundation must be based on site-specific geotechnical determination. Given the discontinuous permafrost at Fort Wainwright a thermosiphon or adjustable screw-jack maybe required to maintain thermal stability and allow for adjustments due to frost heave. Standard spread footing may not be appropriate.

Structural steel frame with insulated metal sandwich panels. All steel and connections must be rated for service at -50 degrees F to prevent brittle fracture.

4.1.2 Building Envelope

Insulated walls and roof shall meet or exceed ASH RAE 90.1 standards for climate zone

8. A continuous vapor barrier is mandatory on the “warm side” of the insulation.

Windows will be triple-pane, gas filled with thermal frames. Windows must Energy Star criteria for the region.

Door will be hallowing metal with thermal break grade 1 hardware (BEST lock compatible, and heavy-duty weather stripping with an adjustable sweep.

4.1.3 Mechanical and Electrical

Heating= a wall-mounted electric heating/AC unit sized to maintain 70F at an outdoor temperature of -50F. The unit must include a quick recovery feature and override for extended shutdowns.

Electrical= All exterior conduits, fixtures and wiring must be cold-weather listed to -50F.

A type 1 or type 2 surge protection device (SPD) is required at the service entrance.

Electrical power shall be ran from current on location disconnect or established demarcation point. (If option of demo is awarded use of location power is authorized).

Lighting= Provide dual circuit interior and exterior lighting (white and red LED lamps).

All fixtures must be vapor-proof, guarded, and UL-listed for wet/cold locations. Light switches for shall have protective covers to prevent accidental use during night operations.

Lightening protection is required.

4.2 Construction of General Instruction Building (GIB)

General requirements- Contractor shall build one (1) single story 20’ x 40’ GIB

4.2.1 Foundation and Structural

Foundation= a reinforced insulated monolithic slab-on-grade foundation. The design must include a minimum of 4” of rigid non-frost-susceptible insultation (high density XPS) under the entire slab and extending vertically along the slab edge to below the frost line.

Structural= Wood or metal-framed structure with insulated walls and roof meeting ASH RAE 90.1 for Climate Zone 8. Sheathing must include 7U16-inch OSB under the gypsum wallboard for added rigidity.

4.2.2 Building Envelope

Insulated walls and roof shall meet or exceed ASH RAE 90.1 standards for climate zone

8. A continuous vapor barrier is mandatory on the “warm side” of the insulation.

Windows will be triple-pane, gas filled with thermal frames. Windows must Energy Star criteria for the region.

Doors will be hallowing metal with thermal break grade 1 hardware (BEST lock compatible, and heavy-duty weather stripping with an adjustable sweep. Two exit doors are required. (See concept sketch)

4.2.3 Mechanical and Electrical

Heating= a wall or ceiling-mounted electric heating/AC unit sized to maintain 70F at an outdoor temperature of -50F (may require two heater systems). The unit must include a quick recovery feature and override for extended shutdowns.

Electrical= 100-amp service entrance with meter base. Outlets spaced evenly as specified (2 each on long walls 1 each on short walls). Electrical power shall be ran from current on location disconnect or established demarcation point. (If option of demo is awarded use of location power is authorized).

Lighting= Provide dual circuit interior and exterior lighting (white and red LED lamps).

All fixtures must be vapor-proof, guarded, and UL-listed for wet/cold locations. Light switches for shall have protective covers to prevent accidental use during night operations. Interior ceiling mounted lighting shall be LED long tube and four individually mounted single (light bulb) red light.

Fire Alarm: A Monaco Fire Alarm system fully compatible and integrated with the main Fort Wainwright system is required.

Lightening protection is required.

5 Submittals and Controls

The Contractor shall submit a comprehensive Quality Control Plan (QCP) and an Environmental Protection Plan (EPP). The EPP must include a site-specific erosion and sediment control plan. All submittals require COR approval with DPW concurrence.
