Preparation for Installation of the Instrument Landing System
This design-build project provided preparatory work for the installation of a new Instrument Landing System (ILS). The ILS consists of an antenna system with primary components at two sites (i.e., Glideslope and Localizer) located at opposite ends of the runway. Work at the two sites consisted of removing and disposing of existing antenna equipment and equipment pads; site preparation for new equipment pads; installing underground conduits for power and communications cabling; installing grounding systems; constructing new equipment pads; and paving new access roads. 1,700 LF of underground fiber was installed. 500 LF of power ductbank and three transformers were installed. Airfield markings, signage and installation of new survey monuments for ILS calibrations were also part of the scope this contract.
Restore Ventilation NHB B1, Phase II
Code-required modification and replacement of 7 air handling units (AHUs), 1 heating & ventilation (HV) unit, 19 fans, and 14 pumps on HVAC systems serving administrative areas, operating rooms, exam rooms, laboratories, and service areas. Extensive phasing, infection control, and outage coordination was required to maintain hospital operations.
Security Alarm Upgrade
Design-build upgrade replacement and integration of legacy Access Control Systems (ACS) and Intrusion Detection Systems (IDS) throughout Naval Base Kitsap, Bangor and Bremerton. Scope encompassed networking new ACS and IDS in over 100 different facilities serving over 150 different commands and using the Navy's secure network to connect signals to the Regional Dispatch Center.
Design-build renovation and 2,000 SF cast-in-place concrete addition to convert portions of an existing vehicle garage facility into two separate armories complete with high-severity, bullet-resistant entry doors and weapons issue ports; Class 5A armory vault issue doors; specialized ventilation for weapons cleaning equipment; and administrative and staff offices.
Replace Boilers 1 & 2 at Steam Plant
Design-Build Replace Boilers 1 and 2 at the Steam Plant, B384 included the design of a new steam system, demolition and removal of two of three 45,000 pounds per hour (pph) (1300 boiler horse power (BHP)) water tube boilers in the central heating plant and installation of two new 20,700 pph (600 BHP) fire tube boilers. Steam service was maintained by the third existing boiler while replacement work was completed. Boiler replacement scope involved structural upgrade of the existing raised concrete floor slab, reconnection of all services, including feedwater, vent piping, fuel piping, and instrumentation.
Energy Conservation, Phase 3
Design-build energy conservation project consisting of a combination of lighting and lighting control strategies; HVAC optimization via use of VFDs and controls; water conservation measures; point-of-use hot water heating; thermal envelope upgrades; weatherization improvements; and infra-red heating in 36 different buildings.
Design-build replacement of an obsolete quartz halogen backlighting system with a new, energy-efficient LED system for the high-security Main Limited Area (MLA). Design work included engineering and photometrics. Provided new electrical infrastructure to support the four mile perimeter protection system. Phased construction to maintain perimeter protection throughout construction.
Child Development Center
Design-build 27,000 SF child development facility providing administrative offices, auditorium, commercial kitchen, and 17 classrooms with capacity for 218 children. 6.5-acre site development included 78 parking stalls, covered walkways, and three play areas with state-of-the-art play equipment. LEED Gold certified design featured solar panels, a wind turbine, LED lighting, and accommodations for future geothermal.
Repairs of BUMED Facilities, B993
Design-build repairs at Naval Air Station Whidbey Island Hospital including: Provision of a new sloped roof structural attic truss over the existing roof of the "Duct House" sheltering multiple electrical conduits. Replace existing roof at the Hospital’s Emergency Management, Linen Inventory, and Mail Room areas. Restore loading dock and construct a ramp providing a warehouse receiving area and emergency egress. Provide three supplemental cooling only units.
Refurbish Track & Field
Design-build replacement of existing track and field facility using state-of-the-art, SPRINTURF Ultrablade MX™ synthetic turf over a meticulously prepared subgrade with an extensive subsurface drainage system. Worked with the Navy to resolve cost and time impacts associated with unsuitable soil materials encountered beneath a significant portion of the field.
Install Active Vehicle Barriers
Design-build installation of two active vehicle barrier systems at the Trident and Trigger base access gates. Designed and installed power, drainage, and control utilities in support of the vehicle barrier systems. Coordinated vehicular and pedestrian traffic control with construction activities to maintain constant access through these two primary base access points.
