What GBC Construction LLC does

GBC Construction LLC is a privately held regional general contractor founded in 2005 and headquartered in Corvallis, Oregon. The firm provides full-service general contracting, Construction Management at Risk (CM/GC) delivery, and pre-construction services to public and private clients across Oregon and Washington, with specialized vertical focus in education (K-12 and higher education), healthcare, retail, and commercial/private industry. The company's portfolio includes more than 223 education projects, 343 healthcare projects, and 728 self-perform jobs, with anchor institutional clients including Samaritan Health Services, PeaceHealth, Oregon State University, University of Oregon, Western Oregon University, Macerich Inc., and Rouse Properties.

The firm's business model is project-based and bid/negotiated, with revenue generated through hard-bid general contracting (one-time project contracts), CM/GC at-risk delivery, and pre-construction consulting engagements. Self-perform capabilities across 728 jobs indicate significant in-house trade execution, supporting quality and schedule control on complex projects such as occupied healthcare renovations (MRI installations, hybrid operating rooms, cancer centers) and education campus work requiring coordination around academic calendars. Distribution is entirely direct, with GBC engaging project owners, architects, and engineering firms through RFP responses, relationship-based repeat business, and consulting-led CM/GC pre-construction involvement.

GBC is owner-operated by a small leadership team (Vice President/Senior Project Manager Cody Timmins is a part owner) supported by project managers, superintendents, project engineers, and a project coordinator. The firm emphasizes relationship-driven repeat business, a strong safety program with an Experience Modification Rate of 0.63 in 2025 (below the industry average of 1.0), OSHA 30 training requirements at the foreman level and above, and deep institutional relationships across Oregon and Washington. There is no disclosed external equity, debt, or institutional investment, and the company holds Oregon CCB# 166612 and Washington WACL# GBCCOCL859J2.
