About the company
R.M. Towill Corporation, a Hawaii-based civil engineering and architect-engineer services firm, operates as a for-profit Subchapter S Corporation subsidiary of Kilohana Corp and delivers infrastructure design, water system studies, and engineering consulting to the Department of Defense and related federal agencies as a prime contractor (99% of recent awards) under full-and-open competitive procurement with no set-aside designations.
The vendor's federal footprint concentrates heavily in the Pacific theater, with 82% of recent awards funded by Department of the Army entities. The Department of the Army Corps of Engineers Engineering District Honolulu dominates both by dollar value and project scope, accounting for 38 awards with $250.3 million in combined potential value — nearly the entire portfolio. This customer concentration reflects R.M. Towill's geographic specialization: work spans Hawaii, Guam, the Northern Mariana Islands, Micronesia, American Samoa, and the Marshall Islands, with primary performance at military installations including Fort Shafter, Wheeler Army Airfield, and Schofield Barracks. The Department of the Navy (28 awards) and Department of the Interior Fish and Wildlife Service (15 awards) represent secondary customers with far smaller dollar exposure. Obligated dollars stand at $73.2 million (29% of combined potential value), indicating a portfolio weighted toward active execution against multi-year vehicle ceilings rather than small completed task orders.
R.M. Towill holds two significant architect-engineer IDIQs with USACE Honolulu. The primary vehicle is a $190 million Indefinite Delivery Contract for civil engineer services awarded in January 2025 with a base period running through February 2030; the second is an $18 million civil services contract through August 2027. Recent delivery orders under these vehicles include a $3.64 million firm fixed-price order (December 2025) for water distribution line design and construction at Fort Shafter, a $1.44 million order (July 2025) for cast iron pipe replacement under Wheeler Army Airfield, and a $2.56 million order (September 2022) for transite water line replacement and fuel station infrastructure at Schofield Barracks. Additional historical work includes an $851 thousand water system study report at Fort Shafter (September 2022) and a $2.27 million storm drainage study at Schofield Barracks (September 2021).
Activity levels have been episodic — one or two awards annually in 2020–2021, four awards in 2022, two in 2024, and four in 2025 — reflecting the lumpy award cadence typical of long-cycle military infrastructure projects. Three awards with combined potential value of $7.6 million face recompete within the next twenty-four months. R.M. Towill subcontracts minimally (1% of awards), with recent sub work including engineering on a potable water tank replacement at Camp Smith under Dawson Technical, Inc. (November 2024) and survey and design services on a Lahaina sewer system project under Dawson McG, Inc. (August 2024). The vendor's subsidiary Rmtc OSK Joint Venture appears in the corporate structure but carries no visible federal award activity in the source. The vendor's NAICS and PSC footprint reflect its core identity: engineering services (39 awards), architectural services (5 awards), and surveying work (2 awards), with PSC codes dominated by architect-and-engineering general services for design, landscaping, and inspection work.
