Fairless Hills RNG Facility

Cambridge provided construction management services for the Fairless Hills RNG Facility and delivered a complex gas upgrading facility that captures landfill gas from 314 wells at the active Fairless Hills Landfill and 290 wells from the closed GROWS-North Landfill. The scope of work required coordination of multiple interface systems, including gas collection infrastructure, process equipment, and interconnection facilities, to ensure reliable conversion of landfill-derived biogas into a market-ready renewable fuel. The two 6,000-SCFM methane refineries are comprised of two 19,700 SF PEMBs, 32,000’ of gas piping, 168 tons of structural steel for pipe racks, and 2575’ of dual 24” HDPE pipeline constructed between the booster building and the RNG facilities. An existing workshop building was repurposed and converted into a Booster Building which houses two 1,200 HP compressor skids. Another challenge of the project was having to locate the new blower motors into an existing building adjacent to the site that was a half mile from the new refineries. In addition, the building was retrofitted with an electrical room, UPS system, Fire Alarm, and HVAC. The facility is serving as the primary long-term gas management solution for the Fairless Hills complex and enabled the decommissioning of five existing enclosed flares previously used for landfill gas control.
