What Calibre Engineering does

Calibre Engineering is a multi-disciplinary engineering services firm headquartered in Highlands Ranch, Colorado, with additional offices in Irvine, California, and Wilmington, North Carolina. Founded in 2000 by Gregory Murphy, the firm operates as a privately held Service Disabled Veteran Owned Small Business (SDVOSB), CVE-Verified through the Center for Veteran Enterprise, providing preferential access to federal set-aside contracts. The firm delivers engineering consulting and design services across eight service lines: Civil Engineering, Structural Engineering, Construction Phase Services, Water Resources, Whitewater & River Engineering, Swiftwater Rescue Facilities, Municipal Services, and Federal Services. Calibre employs an estimated 50–100 personnel, including 20 licensed professional engineers credentialed in 31 states, and reports having completed more than 1,000 projects in the past decade.

The firm's technology base rests on human-expert engineering judgment rather than proprietary software platforms; core technical capabilities include 2D hydraulic-hydrologic modeling, BIM for healthcare and federal facilities, LEED-certified sustainable design, and a proprietary swiftwater rescue training facility system featuring iPad-controlled real-time adjustment of water depth, velocity, and scenario configuration. The whitewater division, established through the 2023 acquisition of S2o Design & Engineering led by three-time Olympian Scott Shipley, brings 45+ completed projects globally including five Olympic-standard venues and award-winning designs such as the U.S. National Whitewater Center and Montgomery Whitewater. The firm pursues federal contracts through IDIQ vehicles and QBS procurement, municipal work through on-call contracts (25 active relationships), and private developer engagements through repeat-client referrals and teaming with primes such as AECOM, Burns & McDonnell, JAMA, and OLC Architecture.

Calibre generates revenue through professional services fees billed as fixed-fee design contracts, time-and-materials construction phase services, and contract administration. Project values range from small municipal tasks to multi-million-dollar federal infrastructure engagements, with the $28M Dallas Fort Worth National Cemetery Phase 4 cited as a representative federal anchor. The firm serves a diversified customer base spanning federal civilian (VA, NPS), federal military (USACE, USAF), municipal governments across Colorado and beyond, and private developers including McWhinney, REVESCO, Sasaki, Holder Construction, Mortenson, and United Airlines. International project execution spans the United Kingdom, Slovakia, Spain, New Zealand, India, and the Bahamas, primarily through the whitewater division. The company is family-owned with a 2024 ownership diversification event and reports no external institutional capital.
