The Honolulu High Capacity Transit Corridor Project (HHCTCP) required a Maintenance and Storage Facility (MSF) to service, inspect, and store the fleet of vehicles that the system will operate.  The completed MSF is located on about a 43-acre sloping site of vacant land.  The Design-Build Team including WCIT Architecture’s scope was to design and construct of the HHCTCP MSF.  The Design-Build Team was responsible for completing the design, obtaining necessary permits, and constructing all the site work, tracks and buildings. There was an extensive amount of grading that needed to be done and construction of retaining walls in order to transform this sloping site into a site suitable for the intended use as a transit vehicle servicing facility. There are four buildings: The Operations and Servicing Building (OSB) which has approximately 140,000 gross square feet and is three levels including a Yard Control Tower;  The Maintenance of Way (MOW) Building which is approximately 60,000 square feet and two levels;  The Train Wash Facility (TWF) with a gross area of approximately 15,000 square feet;  Wheel Truing Facility (WTF) with a gross area of approximately 2,000 square feet.
