What RTM Engineering Consultants does

RTM Engineering Consultants is a national multidisciplinary engineering firm founded in 1981 in Schaumburg, Illinois, specializing in MEP (Mechanical, Electrical, Plumbing), Civil, and Structural engineering design for the built environment. The firm serves healthcare, education, commercial, industrial, hospitality, government, data center, and national retail accounts with a portfolio of specialized capabilities spanning commissioning, arc flash analysis, energy modeling, LEED certification, fire protection, refrigeration design, architectural lighting design, and acoustics. Differentiated technical offerings include net-zero-ready design, hospital and education microgrid engineering (e.g., 250-kW solar array for Kaiser Permanente), and advanced data center cooling (direct-to-chip liquid cooling and ice storage achieving PUE as low as 1.035 for AI/HPC workloads) plus battery energy storage system integration. RTM is licensed in all 50 states, operates 26 offices across the United States, and employs 600+ professionals, having grown from a 3-person mechanical engineering team through organic expansion and more than 40 acquisitions since 2011.

The firm is privately held under a ~36-partner ownership structure in which leaders of acquired firms typically become RTM principals. In September 2022, RTM received a strategic minority investment from MML Capital, an international mid-market private equity firm with over $5 billion AUM, earmarked to fund expansion of technical capabilities, geographic reach, and service offerings. Leadership remains with the founding family: Ramesh Mirchandani serves as Founder and President, and Tony Mirchandani serves as CEO; the broader C-suite includes a CFO (Barry Margolin), Chief Growth Officer (Jenny Riley), and a Director of M&A and Strategic Initiatives (Ben Sermersheim), reflecting the firm's growth-by-acquisition orientation. RTM has received sustained industry recognition, including ENR Top Design Firm (2021-2025), MEP Giants (2015-2025), Zweig Best Firms to Work For (2014-2025), and six appearances on the Inc. 5000 list.

Revenue is generated through project-based professional services fees for engineering design, consulting, commissioning, and construction administration, with contracts that often span multiple years. RTM pursues enterprise clients through direct sales relationships cultivated by principals and business unit leaders, targeting project owners, architects, and general contractors on large-scale construction and renovation projects. The go-to-market pairs local market coverage through the nationwide office network with national-scale resources, enabling the firm to serve both regional accounts and national programs such as ALDI's prototype retail engineering. The combination of a 45-year operating history, 26-office footprint, 600+ professionals, and a proven M&A roll-up model positions RTM as a scaled, roll-up-driven engineering platform rather than a project-by-project consultancy.
