Calcon Constructors

What Calcon Constructors does

Calcon Constructors, Inc. is a privately held, employee-owned commercial general contracting firm founded in 1981 and headquartered in Englewood, Colorado. The company provides full-service general contracting, construction management (CM/GC delivery), and design-build services for clients across the Rocky Mountain region, with selective projects extending into Arizona. Approximately 90% of Calcon's work is sourced from repeat clientele rather than competitive bid, reflecting a relationship-driven go-to-market motion built over four and a half decades. The firm assembles dedicated project teams (principal, project manager/estimator, project coordinator, superintendent) for each engagement and produces customized operation and maintenance manuals as a standard closeout deliverable.

Calcon organizes its project portfolio across six vertical segments: healthcare/medical facilities (its largest specialization, with American Hospital Association certified constructor credentials), multifamily residential (market-rate, affordable, and senior living), commercial office, technical/high-tech facilities (data centers, broadcast studios, central plants), community/public facilities, and retail (notably automotive dealerships). Notable clients include HCA HealthOne, Centura Health Care, Catholic Health Initiative, Spectrum Retirement Communities, Stevinson Automotive, BioMed Realty, and Metro West Housing Solutions. The company has delivered more than 21 million square feet of built space historically, with marquee projects such as the Sky Ridge Medical Campus (829,964 SF) and Littleton Adventist Hospital (209,000 SF).

Calcon generates revenue through negotiated project-based professional services contracts. Pricing is per-project and not publicly disclosed, though AGC award categories indicate frequent project sizes in the $10M-$40M range and large healthcare builds above $40M. The company employs 101-250 people with 60% of staff having tenures exceeding 6 years, supporting deep institutional knowledge of Colorado's subcontractor base, regulatory environment (LIHTC, Davis-Bacon, healthcare compliance), and BIM-enabled MEP coordination. BIM is used as the primary digital technology platform for complex projects; no AI/ML capabilities are disclosed. Revenue figures are not publicly disclosed; headcount and project scale proxies imply an annual revenue band of approximately $50M-$100M. The company maintains private, insider-owned status with no venture capital, private equity, or external institutional investment.
