What CCS International does
CCS International is a U.S.-based construction advisory firm founded in 1979 that acts as an independent owner's representative, providing project management, cost management, project controls, and advisory services to capital project owners across the public and private sectors. The firm serves 3,000+ clients and has completed 10,000+ projects, with cumulative project value exceeding $120 billion across 11 verticals including federal government, healthcare, higher education, cultural institutions, municipal, criminal justice, aviation, transportation, housing, K-12, and corporate/private. Named clients include the U.S. Department of State, Smithsonian Institution, Johns Hopkins Medical Center, University of Chicago, Texas A&M, Argonne National Laboratory, and the National Gallery of Art.
The firm's core technology is its proprietary "Ripple Effect" methodology, which emphasizes that project cost and delivery are most influenced in pre-design and design stages rather than during construction, and integrates pre-design, design, bid, and construction phases through value engineering, cost estimation, and risk mitigation. CCS operates a CMMC/NIST 800-171 compliant secure enclave that enables it to handle Controlled Unclassified Information on federal defense contracts, and uses MII software for cost estimation and Monte Carlo–based schedule risk assessment. Staff hold LEED and Energy Star certifications, and the firm averages 20 years of experience per employee across its Oak Brook, Illinois headquarters and three regional offices.
CCS generates revenue through project-specific, quote-based professional services engagements on multi-year contracts, typically structured as owner's representative, cost management, or advisory mandates with fees tied to scope, complexity, and duration. The go-to-market is enterprise field sales targeting capital project owners in federal, healthcare, higher education, cultural, municipal, and private sectors, supported by industry association partnerships (AIA, COAA, ULI, IFMA, SMPS), thought-leadership content marketing, and long-term client referrals. In April 2026, CCS was acquired by Consertus, a portfolio company of private equity firm RTC Partners, and concurrently spun off its Tenzing One capital project management software platform into an independent entity led by founder Ian Parr, who retired after 47 years.
