What Interface Construction Corporation does

Interface Construction Corporation is a privately held, union-affiliated, MBE-certified general contractor and construction management firm headquartered in St. Louis, Missouri. Founded in 1978 by Samuel Hutchinson as a concrete subcontractor and repositioned in 1988 as a full-service general contractor and construction manager, the company now offers preconstruction, construction management, and general contracting services across five specialized verticals: healthcare, research facilities, higher education, industrial/utilities, and institutional/cultural. It differentiates itself through a self-performing model in which in-house tradespeople execute up to 40% of annual project volume in carpentry, drywall, concrete, and millwork, giving Interface direct control over schedule, quality, and safety on complex occupied-building projects.

Interface targets enterprise and institutional clients in the St. Louis metropolitan area and broader Midwest (Missouri, Kansas, Illinois), with named customers spanning SSM Health, BJC Healthcare, Washington University School of Medicine, Total Access Urgent Care, UPS, Ameren, the St. Louis Zoo, the St. Louis Science Center, and the Missouri Veterans Home. Revenue is generated through project-based contracts, typically cost-plus or fixed-price, with disclosed project values ranging from roughly $600K public-space renovations to $11.5M hospital expansions. The firm holds industry certifications including MBE, union contractor, AGC and ASA memberships, ASHE and MOSHE healthcare affiliations, ISNetworld and Browz safety verifications, and OSHA-AGC partnership status, supported by an Experience Modification Rate of 0.62 and a 100% OSHA-trained workforce.

The company is currently led by CEO Stanford Richardson III and President Angie Abernathy following founder Samuel Hutchinson's death in January 2021. With approximately 100 employees and historical annual revenue above $45 million, Interface has remained operationally stable, earning the 2025 ASA General Contractor of the Year Award (Category C) and maintaining an active pipeline of occupied healthcare, research, and institutional renovations alongside productized urgent-care delivery for Total Access Urgent Care. The business is privately held with no disclosed institutional investment or parent company.
