Job 130
The scope of work for this project included the modernization of the propane gas distribution system serving buildings throughout the park headquarters. Existing individual above-ground 500-gallon LPG tanks were removed and replaced with a centralized underground storage and distribution system designed to improve efficiency, reliability, and site functionality.
Site Work Solutions installed two (2) underground 6,500-gallon LPG storage tanks at a centralized tank farm. A new underground gas distribution network was constructed to deliver propane from the tank farm to buildings throughout the park requiring gas service. A direct-fired LPG vaporizer was installed to ensure that only propane vapor was distributed through the system, and a truck-fill station was provided to facilitate efficient refueling of the underground storage tanks.
To minimize excavation and reduce impacts to the surrounding site, the new underground gas distribution piping was routed, where feasible, along the same alignment as proposed underground electrical power and telecommunications infrastructure. Gas piping consisted of HDPE fusion-welded pipe for systems operating at 30 psi or less and Schedule 40 welded steel pipe for systems operating between 30 psi and 250 psi.
The project also included installation of new smart gas meters at the inlets of all residential buildings, providing enhanced monitoring and tracking of individual gas consumption.
The existing above-ground propane tanks were leased by the National Park Service from AmeriGas in Chester, California. Site Work Solutions coordinated with AmeriGas to facilitate the removal of the existing tanks and associated concrete bases after the new centralized tank farm and distribution system were operational.
The completed project provided a centralized, modernized LPG distribution system that enhanced operational efficiency, improved monitoring capabilities, and reduced the number of individual propane storage tanks throughout the park headquarters.
