Replace Fender Piles on West Side Pier B213, Manchester Fuel Depot
Design and replace the existing barge fendering system on the west side trestle of the fuel pier at Manchester Fuel Depot. Existing fendering system was removed with special care to prevent injury or damage to the existing work which remained. A new complete fendering system was installed utilizing 20 driven concrete piles 24 inches (square) and a continuous camel log system and arch fenders. The fuel pier and surrounding mooring area remained operational during construction requiring construction phasing.
Repair Roof VA Puget Sound Healthcare System
Repair existing roofs on multiple Veterans Administration Health Care buildings at the Seattle campus. Work included demolition and removal of existing roofing, structures and temporarily utility, exhaust fan and other mechanical equipment disconnects and repairing the roofs per the Green Environmental Management System (GEMS). New roofing systems including insulation was installed on flat roofs. The buildings were occupied which required coordination with building managers and attention to noise levels and odor issues due to proximity to air intakes. Enhanced security requirements and coordination were required for access to restricted areas.

Repair Building Envelope B707, JBLM, WA
Repair Building Envelope J00707 (Historic Building). Repairs consisted of sealing all attic building openings with insulation and sealants. Fabricating and installing covered louvered openings on the Mechanic Room double doors. Installing covers to existing wall openings with galvanized steel sheet and insulation. Installing rigid board insulation in the Mechanical room for improved thermal and noise performance.
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.
Backflow Prevention for Building Isolation
Replaced existing domestic water backflow assemblies at the Veterans Administration Puget Sound Health Care System in Seattle with reduced pressure backflow assemblies at two connections to the supply loop. Design changed the existing below grade backflow assemblies with above grade replacements in insulated enclosures.
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.
