Rathgeber/Goss Associates

What Rathgeber/Goss Associates does

Rathgeber/Goss Associates, PC is a privately held structural engineering consulting firm founded in 1991 and headquartered in Rockville, Maryland. It provides structural design and analysis services for the building industry, serving architects, contractors, and building owners on a project-by-project basis. Service lines include structural design and analysis for new buildings, renovations, remodeling and additions, feasibility studies and rehabilitation assessments, expansion potential evaluations (horizontal and vertical), structural bracing retrofits for seismic and wind loads, expert witness testimony, and construction phase services (formwork/reshoring design, wall bracing, shoring, and tower crane foundations). The firm is structured as a Maryland professional corporation, is registered as a certified small business, and lists direct principal involvement across all project phases as a defining operating characteristic.

The firm operates analysis and design programs for reinforced concrete, structural steel, wood, and masonry, supplemented by AutoCAD and Revit-based BIM workflows for drawing preparation and modeling. It maintains Professional Engineer registrations across 10 states and has experience under all major U.S. building codes (IBC, ASCE, BOCA, UBC, SBC, ANSI), with an in-house Quality Assurance Program and $2,000,000 in liability insurance. Marquee projects include the Capital One headquarters in McLean, more than 25 data centers totaling over 7 million square feet in Ashburn and Manassas, Virginia for clients such as CloudHQ and Dupont Fabros, the Kettler Capitals Iceplex in Arlington, and the 1400 Crystal Drive repositioning in Arlington.

Go-to-market is sales-led and relationship-driven: the firm markets primarily through its website portfolio and a "Request For Proposal" intake form, complemented by industry recognition through the Structural Engineers Association of Metro Washington (SEA-MW), where co-founder Michael J. Goss served on the Board of Directors for 25 years. Revenue is generated on a project-basis fee-for-service model under multi-year engagements with architects, contractors, building owners, and institutional clients. The firm has remained privately held and founder-controlled since 1991, with no disclosed external investors, M&A activity, or public market presence.
