R.M. Towill Corporation

What R.M. Towill Corporation does

R.M. Towill Corporation (RMTC) is a Honolulu-headquartered civil engineering professional services firm founded in 1930, operating today as a 100% employee-owned subsidiary of Kilohana Corporation with a staff of 125 Hawaii residents across offices in Honolulu and Kailua-Kona. The firm delivers vertically integrated services across five practice areas — civil engineering, water and wastewater engineering, surveying and mapping (including GPS, aerial photography, LiDAR, and drone services), planning and permitting, and construction management — and has completed over 25,000 projects in Hawaii and the broader Pacific Basin over its 95-year history.

The firm's revenue model is project-based fee-for-service professional consulting, secured through competitive bidding, RFPs, and direct negotiations with government agencies (City and County of Honolulu, State of Hawaii departments, U.S. Army Corps of Engineers, DOD), and private developers (Haseko, Hunt Companies Hawaii, Ritz-Carlton projects). RMTC typically serves as prime consultant on large public infrastructure programs — exemplified by the $267 million Honouliuli Wastewater Treatment Plant Phase 1B, the $250 million Kapalama Container Terminal, and the $351.1 million Mauka Concourse Extension at Daniel K. Inouye International Airport — bundling surveying, design, permitting, and construction management services under single engagements.

RMTC's go-to-market is enterprise field sales targeting institutional clients through relationship-driven business development, supplemented by industry award visibility (multiple Grand Conceptor Awards, ASCE and NAIOP recognitions) and LinkedIn/website presence. The firm's competitive positioning rests on regulatory expertise (including a former Honolulu Director of Planning and Permitting on staff), deep local relationships, and senior leadership averaging 35 years of professional experience — most of it at RMTC itself. Technology is conventional civil/surveying tooling augmented by LEED-accredited sustainable design practices; no AI/ML, software, or platform products are part of the offering.
