RSC

What RSC does

RSC operates as a private engineering and environmental services consulting firm, structured around three service clusters: site/civil engineering (geotechnical, environmental, energy, earthquake/seismic), traffic/transportation and landscape architecture (with waterfront/marine, PFAS, demolition, and cultural heritage sub-practices), and a Digital Solutions platform (systems development, environmental data management and analytics, asset and facility management, GIS mapping and consulting). The firm serves enterprise, institutional, and government clients across infrastructure, commercial, residential, healthcare, aviation, and energy end markets, with marquee engagements including Vantage Data Centers' WA1 Campus in Quincy, WA, JFK International Airport Terminal One in Jamaica, NY, the Arsenal Trade Center e-commerce facility in Sayreville, NJ, and the Meadowlands Solar Array.

The business model is project-based professional services revenue generated through direct enterprise engagement, referrals, and responses to RFPs, delivered through a network of offices spanning 23 US states and 5 international markets (UK, Canada, UAE, Greece, Panama). The firm supports demand generation with content marketing channels including newsletters, an industry podcast, regulatory updates, and earned media coverage, while enterprise distribution runs through a direct field sales motion led by local office teams. In 2025 the firm acquired Kirkman Engineering to expand in the Dallas-Fort Worth Metroplex and achieved ISO 27001 cybersecurity certification, signaling both geographic and compliance-driven growth. The firm is privately held with no disclosed parent, investors, or revenue figures, and its multi-entity structure (footer notes that "Langan" encompasses multiple legal entities) and active M&A posture indicate a mid-sized consultancy scaling both organically and through acquisition.
