What LARSEN & LANDIS, INC does
Larsen & Landis, Inc. is a Philadelphia-headquartered structural engineering firm founded in 2006 by Eric Larsen and Bradley S. Landis. The firm provides structural engineering and design, evaluation of existing structures, construction support, historic preservation, and façade review services to architects, developers, design professionals, construction firms, and building owners across the Mid-Atlantic region (Pennsylvania, Delaware, New Jersey, Maryland, Rhode Island, and Ohio), with a satellite outpost in Oro Valley, Arizona. Service scope spans educational, commercial, industrial, residential, recreational, historic, and religious project types, with material expertise across steel, concrete, masonry, timber, light gage, and cold-formed metal framing systems.
The firm operates as a privately held professional services practice with approximately 15 staff, including four Principals, senior project managers, licensed P.E.s, engineers-in-training (E.I.T.s), and administrative support. Offices are located in Philadelphia (headquarters in a renovated historic Fishtown church the firm designed itself), Wilmington DE, Fort Washington PA, and Oro Valley AZ. Client acquisition is relationship-driven, with deep repeat partnerships with architectural firms including ISA (Insite Architecture), CICADA Architecture/Planning, ABHA Architects, and John Milner Architects producing multi-project pipelines across institutional, higher-education, religious, residential, and historic preservation work.
The business model is project-based professional services billing, with revenue generated through per-project or hourly structural engineering consulting engagements scoped to client requirements. No public funding, external investment, acquisitions, or productized technology offerings are present; the firm operates as a founder/principal-owned practice following Eric Larsen's passing in 2017, with Bradley S. Landis continuing as President and Principal Structural Engineer. Marketing is conducted indirectly through project portfolio reputation and direct inquiry rather than paid channels.
