Client: Air Force Civil Engineer Center
Location: Wake Island
Completion Year: 2018
Scope of Work:
- Sophisticated Logistics
Brice is performing the design build construction of a water distribution system, demolition and reconstruction of the Building 1503 Emergency Generator Building, and repair of two buildings (Buildings 1502 Terminal Building and 1104 Dining Facility) located on the Wake Island Airfield. Both the water system and buildings were deteriorating after years of use and from the salt corrosion that is typical of island environments.
Our design work consisted of the review of a 100% design provided by the client. Working with our engineer of record, we identified design upgrades required to achieve the client’s project goals and objectives, i.e. discrepancies arose between the timing of the 100% design versus current conditions. For example, our site visit revealed severe concrete spalling in Buildings 1502 and 1104; rusting rebar was expanding and causing concrete walls to crumble. Through discussions and negotiations with the client, multiple contract modifications totaling $3.4 million were made to accommodate these changed conditions. We revised our work plans and schedule, resequencing the work into two phases: phase 1 included upgrades/replacement of the water distribution piping system and demolition and construction of the Generator Building (Building 1503) during the 2017 field season; phase 2 includes repairs to the Terminal Building and Dining Facility in the 2018 field season.
Design Build the Water Distribution System—In 2017, Brice began repairs and upgrades to the water distribution piping system to provide more water volume and hydrants for emergency fire suppression. The current system was undersized and deteriorated and had known water loss. We installed nearly 35,000 linear feet of pipe with 59 services (buildings supplied with water via new curb stop, backflow preventer, and associated valves), 35 fire hydrants, and completed the construction of the new 20’ x 30’ pump house.
In 2018, we will complete the upgrades to the water distribution system. We will replace the main pump #3 with an in-line Triplex Pump Package and two 75 hp fire pumps to centralize water system maintenance into one pump house; and abandon the booster pump stations and original pump house.
Building 1503 (Emergency Generator Building)—Brice demolished the existing generator building and installed a new pre-engineered metal building that will require minimal maintenance. We galvanized the frame and covered the roof and walls with insulated metal panels. We installed an overhead door and a man door on one gable end of the building, the other gable end having a radiator penetration. The interior wall surfaces will be substrates suitable for mounting electrical panels.
Phase 2 work in 2018 will involve the following work:
Repairs to Building 1502 (Terminal Building)—Brice will replace or refurbish existing deteriorated building components to repair the building’s appearance and seal the building to prevent salt air infiltration and corrosion to interior components. Exterior doors and windows will be removed and replaced with windows more suitable for Wake Island’s ocean climate. We will install a new Transportation Security Administration screening room and three complete bathroom remodels, including tile, fixtures, and enclosures.
Building 1104 (Dining Facility)—To weatherize the building, exterior doors and windows will be replaced with products that are suitable for the island’s climate. The air exhaust vents near the entrance will be replaced. On one wall of building, the plywood above windows will have new aluminum siding installed. We will also renovate two bathrooms. Approximately 3,600 square-feet of VCT and asbestos containing mastic will be removed under an asbestos abatement containment enclosure from the Dining Room. New VCT will be installed as a durable replacement.
