ARM Group

What ARM Group does

ARM Group is a Mid-Atlantic engineering and science consulting firm founded in 1998 and headquartered in Hershey, Pennsylvania, operating under parent holding company ARM Group Enterprises Inc. with five wholly-owned subsidiaries (ARM Group LLC, AETA, GSET, CAMCO, AEC, and Taylor GeoServices acquired 2024-09). The firm offers multidisciplinary services spanning civil, environmental, electrical and automation, geotechnical, geophysical, solid waste, water, mine and quarry, natural gas, and natural resources practice areas, delivered by 300+ professionals averaging more than 18 years of experience from 18 offices across Pennsylvania, New Jersey, Maryland, Virginia, and North Carolina.

Core technology assets include the proprietary Grid Gateway integrated grid interconnection solution (combining switchgear, intertie protective relay panel, and data acquisition system in one pre-engineered enclosure), a GIS data management platform built for the largest U.S. brownfield redevelopment at Sparrows Point, advanced gravity meter and borehole geophysical imaging tools, ISO 9001:2015 and UL-508A certified electrical fabrication facilities, AASHTO-accredited soils and materials laboratories, and a pending patent on solar-integrated mechanically stabilized earth berms.

ARM Group generates revenue through project-based professional services fees and hourly consulting rates across enterprise and government clients in energy, development and construction, industrial and manufacturing, solid waste, water, mine and quarry, and transportation markets, supplemented by direct sale of fabricated electrical equipment including the Grid Gateway package. The 100% employee-owned firm pursues growth through repeat A&E engagements (including 27+ year relationships such as Lancaster County Solid Waste Management Authority), RFP-driven enterprise and municipal wins, and tuck-in acquisitions, most recently a 2026-05-12 strategic alliance with Batricity to enter the battery energy storage market.
