Healy Tibbitts Builders, Inc. (HTB) was founded in 1886 by two waterfront workers in San Francisco, CA.  Originally named Healy Tibbitts Construction Company, the business helped to rebuild the city of San Francisco after the disastrous earthquake in 1906, and grew as a marine and foundation contractor, both domestically and internationally.

In 1963, HTB first ventured into the Hawaiian Islands, taking on several challenging projects, including Hawaii Kai Development’s Sandy Beach Ocean Outfall Pipeline, and the US Army Corps of Engineers’ Kahului Harbor Breakwater Repair.  During this time, a permanent office was established in Aiea, HI to handle projects in both Hawaii, and the Pacific Rim.

In the late 1960’s, HTB became a subsidiary to Raymond International, and in the late 1980’s, was sold to its parent company, Weeks Marine, Inc., an Engineering News-Record Top 100 contractor specializing in dredging and marine construction.

HTB has experienced significant growth over the last 25 years. Its affiliations have enhanced the company’s ability to handle larger and more complex projects, due in part to the financial support and abundant equipment resources, now shared with Weeks Marine, Inc. In 2023, the Weeks organization was acquired by Kiewit Corporation to become wholly-owned subsidiaries of Kiewit.
