What Bseg, Llc does

BSEG, LLC (Building Systems Engineering Group) is a full-service consulting engineering firm specializing in mechanical, electrical, plumbing, and fire protection (MEP) systems design for building projects. Founded in 2007 in Allentown, Pennsylvania by three partners — Ahmad A. Mahmud, David R. Pollock, and Robert A. Siglin — who left larger engineering firms to build an independent practice focused on MEP work, the firm operates from a single headquarters at 4949 Liberty Lane, Suite 115, Allentown, PA, and holds professional engineering registrations in 18 U.S. states spanning the Mid-Atlantic, Northeast, Southeast, and Midwest.

The firm delivers four core service lines: Mechanical Engineering (HVAC, geothermal, mission critical design, building management systems, energy recovery); Electrical Engineering (power distribution, emergency power, lighting, fire detection, telecommunications, security); Plumbing Engineering (sanitary, storm drainage, rainwater harvesting, domestic water, fuel gas, medical gas, compressed air); and Fire Protection Engineering (wet/dry sprinkler systems, clean agent systems, standpipes, fire pumps). Technical execution relies on AutoCAD and REVIT for building documentation. Project portfolio spans commercial, healthcare, multi-family residential, retail, hospitality, senior living, education, religious, and sports/recreation sectors, including notable adaptive-reuse assignments such as the Simon Silk Mill (300,000 SF, 2020 Preservation PA award), Oxford Mills (170,000 SF, 2015 Preservation Alliance Grand Jury), and Riverworks (483,000 SF).

BSEG operates as a sales-led professional services firm, generating revenue through project-based consulting fees for engineering design, specifications, and construction administration. Customer acquisition relies on direct relationships, referrals, and repeat engagements with architects, building owners, developers, and general contractors. The firm is structured as a private partnership offering employee ownership participation, with no external investors, no disclosed funding rounds, and no parent company. Pricing is project-specific and not publicly disclosed.
