New construction consisted of a Type III Hydrant Fuel Pump house rated at 2,400 GPM with five 650 GPM Fuel Pumps and an automated PLC based pump control panel; 4 (ea). truck fill stands and 2 ea. truck offload stands with canopies; a POL operations building with fuels lab; Fuel line tie in and installation of 2,200 LF of 12” stainless steel fuel piping providing an 1,100 LF extension to the existing type III hydrant loop connecting to 6 (ea.) existing hydrant pits located on the existing aircraft apron; PCC airfield pavement removal and replacement; installation of two new hydrant fuel pits and one isolation valve pit including high point vent pits and low point drain pits. The airfield apron work was performed in two consecutive phases to minimize impacts to airfield operations. Additional project features included: above ground and below ground fuel piping with supply and return lines; a complete cathodic protection system for the fuel piping; a completely new electrical system and control system meeting NEC class 1 division 1 requirements, an automatic tank gauge and annunciation system; a new storm drainage system around the entire site; painting of all new above ground fuel piping. This was a phased project which required the decommissioning and demolition of the existing fuel storage and distribution system prior to construction of the new pump house.

The project also required demolition of two existing fuel storage and distribution systems and demolition of an existing POL operations building. Specifically, demolition consisted of abandoning existing underground fuel piping in place with concrete slurry fill, demolishing a 2,500 BBL above ground storage tank, demolishing three existing 50,000 gallon underground fuel storage tanks, 2 existing hydrant fuel pits, 4 existing truck fill stands, a bulk fuel storage control building, and excavation & disposal of petroleum contaminated soil. Garco was also responsible for preparation of the tank closure permits and reports for submission to Washington State Department of Environmental Quality. Garco self-performed all PCC airfield pavement, all other concrete work, landscaping, structural and miscellaneous steel erection, decommissioning of existing fuel lines and selective demolition.
