What Tilden-Coil Constructors does

Tilden-Coil Constructors is a full-service general contractor and construction management firm founded in 1938 and headquartered in Riverside, California. The company provides preconstruction planning, Building Information Modeling (BIM) and virtual construction, multiple delivery methods including design-build and construction manager at risk, and site safety management. It serves institutional clients across K-12 education, higher education, civic and government, commercial, healthcare, hospitality, institutional, and memorial sectors, with named projects for the City of Indio, City of Redlands, Riverside County, Cerritos College, College of the Desert, Crafton Hills College, California Baptist University, and Mt. San Antonio College.

The firm generates revenue through project-based general contracting and construction management engagements secured via competitive bid opportunities, client prequalification, and long-standing institutional relationships. Distribution is direct enterprise field sales targeting public agencies, school districts, and college/university systems, supported by subcontractor coordination through an online trade portal. Customer concentration is weighted toward Southern California public-sector and educational clients, with active mandates in 2025-2026 spanning a 43,000-square-foot public safety campus, a new city hall, multi-building community college expansions, and a historic theater restoration.

Tilden-Coil operates three offices across Southern California — Riverside (headquarters), El Segundo (Los Angeles area), and Palm Desert (Coachella Valley) — and is led by President Robert Hildenbrandt. The company is privately held with no disclosed parent company, funding rounds, or institutional investors, suggesting founder or family ownership. Its primary differentiators are 85 years of brand continuity, an experienced leadership bench, and integrated BIM/virtual construction capabilities applied to public-sector delivery.
