What RGCE does

RGCE (Rosenwasser / Grossman Consulting Engineers, P.C.) is a New York-headquartered structural engineering consulting firm founded in 1954 by Robert Rosenwasser. The firm provides professional structural engineering services — design, analysis, and construction administration — for residential towers, mixed-use developments, commercial buildings, hotels, retail, institutional facilities, and select international projects, with a stated specialization in high-rise concrete design including tube systems, post-tensioned concrete, and slender tall buildings with aspect ratios exceeding 10:1. Its technical foundation includes proprietary in-house software for concrete structure analysis developed in the 1970s by co-founder Jacob Grossman, and the firm claims credit for shaping NYC seismic code provisions and delivering the city's first seismically compliant building at 565 Fifth Avenue before such provisions were required.

The firm operates as a privately held New York professional corporation with a single office at 519 Eighth Avenue, 20th Floor, and a publicly visible team of roughly 20 members — comprising licensed P.E.s, a PhD structural engineer, a QPSI-certified associate, a Director of CADD Services, a Director of Business Development, and a Controller. Notable project work spans landmark NYC developments (211 Madison Avenue, Metropolitan Tower, Carnegie Hall Tower, CitySpire, Millennium Hilton) and modern mixed-use commissions such as the ~1,000,000 sq ft 595 Dean Street (Pacific Park) project delivered for TF Cornerstone in collaboration with Handel Architects. Awards include the ULI New York Award of Excellence in Market-Rate Housing Development (2018) and the CIB Award of Merit (2023).

RGCE makes money through project-based professional services engagements sold directly to real estate developers, architects, and property owners. Pricing is quote-based, not publicly disclosed, and the firm engages in no reported outbound marketing beyond its website, LinkedIn, Facebook, and YouTube presence — relying primarily on industry reputation, relationships, and earned-media recognition within the NYC architecture and development community. There are no reported subsidiaries, funding rounds, parent companies, M&A activity, or external investment.
