The company provides consulting, design, and project management services to building owners, developers, architects, and government clients across commercial, education, government, healthcare & senior living, hospitality, labs & research, residential/mixed-use, religious, sports & entertainment, and storage/warehouse segments. Core service lines are MEP engineering, commissioning (including retro- and re-commissioning), sustainability services (LEED administration, ASHRAE Level I/II/III energy auditing, energy modeling), and project management, with a specialized Net Zero Energy Buildings consulting offering developed in-house.

Underlying technical content centers on high-performance building systems: HVAC design, electrical power distribution, fire alarm and plumbing, and emerging pathogen-mitigation technologies including UVC germicidal irradiation, needlepoint bi-polar ionization, advanced MERV filtration, humidity control targeted at 40-60% RH, tunable circadian lighting, and net zero strategies spanning envelope design, HVAC electrification, smart controls, and renewable integration. A codified body of work is published through the firm's COVID-19 White Paper Series authored largely by senior engineering staff.

The business model is professional services delivered on a project-fee basis via direct client engagement, with no intermediary channel partners. The firm operates from regional engineering offices in Columbia MD (corporate), Pittsburgh PA, Salisbury MD, Chicago IL, Dubai UAE, and Mexico City, employing 101-250 people. Lead architects and developers are procured through long-term partnerships with firms including HOK, RKAA Architects, Alliance Architecture, NEXT Architecture, CORE architecture + design, and Grimm and Parker, with the firm typically serving as MEP subconsultant on integrated project teams. Marquee engagements include M&T Bank Stadium (Baltimore Ravens, AGC Build America Award), Heinz Field (Pittsburgh Steelers), The Wharf (Washington DC), National Science Foundation HQ (GSA), Google tenant fit-outs, UPMC healthcare renovations, and Salisbury University's Net Zero Master Plan.
