What Silman does
Silman is a U.S. structural engineering consultancy founded in 1966 in Boston by Bob Silman, now fully integrated as the Buildings Market division of TYLin Group. The firm delivers professional structural engineering services for architectural projects across five core service lines: new construction, renovation, adaptive reuse, historic preservation, and lightweight structures, serving clients in the Americas. Silman is anchored by a preservation-engineering legacy — founder Bob Silman's portfolio included Frank Lloyd Wright's Fallingwater structural stabilization, the Ellis Island Museum of Immigration, Carnegie Hall preservation projects, and the relocation of the National September 11 Memorial Museum's Survivors' Stair — which differentiates the practice within TYLin's broader buildings capability.
Revenue mechanics are project-based professional services: engagements are quoted on a per-project basis (pricing is not publicly disclosed) and delivered through direct relationships with architectural firms, developers, government agencies, and private clients. Go-to-market relies on direct sales, industry referrals within the architecture and construction ecosystem, and digital brand presence via TYLin's LinkedIn, Instagram, Facebook, X, Vimeo, and email channels. The underlying technology stack is conventional structural-engineering design and analysis tooling, with no proprietary software or AI capabilities disclosed; TYLin's separate "Digital Fusion" practice signals broader digital delivery capability at the parent level but is not described as Silman-specific. The business is privately held with no funding rounds disclosed, parented by TYLin, headquartered in Boston, with 101–250 employees.
