What TGRWA does
TGRWA is a privately held structural engineering firm headquartered in downtown Chicago, operating as TGRWA, LLC since July 2000 and tracing its roots to Tylk, Gustafson and Associates, Inc. (founded 1979). The firm provides a full spectrum of structural engineering services — new construction, renovation, investigation, feasibility studies, rehabilitation and repair, value engineering, and peer reviews — for diverse building types including corporate offices, healthcare facilities, hotels and restaurants, educational and religious buildings, municipal and government structures, multi-family residential, retail centers, athletic venues, and special structures such as theaters and data centers. It works across structural materials including structural steel, reinforced and post-tensioned concrete, timber, masonry, and cold-formed steel framing, with documented expertise in complex challenges such as progressive collapse design, high-wind and seismic design, and historic renovation/adaptive reuse.
The firm operates as Engineer of Record on engagements with developers, architects, general contractors, and building owners, delivering services directly from conceptual design through construction administration. Its technical platform is built on industry-standard BIM and CAD tools — primarily Revit and AutoCAD — managed by an in-house BIM/CAD function. Revenue is generated through project-based professional service fees negotiated per engagement, with no published rate card; project durations span multi-year horizons on major adaptive-reuse conversions (e.g., Tribune Tower, LondonHouse Chicago, Arlo Chicago) and shorter cycles on standardized programs (e.g., the Shake Shack national rollout of nearly 200 projects since 2012 across 30+ states).
TGRWA employs 11-50 staff led by six principals (Kevin Wilson, Jon Andrews, David Nickell, Michael Justice, Peter Danos, Roger Reckers) with 25-40+ years of experience each, supported by senior associates, associates, senior engineers, and a dedicated BIM/CAD manager. The firm has no disclosed institutional investors, parent company, or external funding rounds; ownership and control appear to reside with the principals. Geographic reach spans the continental United States, with primary density in the Chicago metropolitan area and Midwest, and expanding federal government work (e.g., Tyndall Air Force Base lodging) supplementing its private-sector base.
