What Madsen Consulting Engineering does

Madsen Consulting Engineering is a New York City-based structural engineering consulting firm founded in 2010 by principals Erik Madsen and Cristian Vimer. The firm delivers structural design across reinforced concrete, structural steel, masonry, cold-formed steel, and wood, with specialization in new construction, renovation and adaptive reuse, special structures (including art installations and temporary works), and affordable housing projects funded by HPD or HUD. It serves a horizontal mix of architects, real estate developers, contractors and steel fabricators, and property owners in the New York metropolitan area, with deep familiarity in navigating approvals from the NYC Transit Authority (MTA), NYC DOT, the Port Authority, and other government agencies.

The firm operates an integrated BIM-to-fabrication workflow that moves from architectural and structural 3D models in Revit through structural analysis in RISA, ETABS, and SAFE, and into construction deliverables including structural and miscellaneous steel shop drawings, connection design, concrete reinforcement detailing, and CNC-ready data via SDS/2 and Rebar Cad. Construction phase services include structural special inspections, temporary shoring design, and demolition drawings. The firm also offers ancillary services such as peer reviews, value analyses, structural condition assessments, feasibility studies, building engineer services, and forensic investigations.

Madsen generates revenue exclusively through B2B professional services fees tied to project scope and complexity, with pricing not publicly disclosed. In 2023, the firm merged with DCI Engineers, a nationwide structural, civil, heavy industrial, bridge, and right-of-way firm, forming DCI+Madsen and extending the combined entity's service coverage across the United States while adding capabilities in mass timber, industrial, and bridge markets. The 16-person local team includes 9 engineers, a dedicated SDS/2 steel detailing manager, and a BIM manager with more than 15 years of Revit experience. The firm's principals have held sustained leadership roles in NYC code development, including service on the 2022 NYC Building Code Revision Committee and Erik Madsen's presidency of SEAoNY.
