What Bowers + Kubota does

Bowers + Kubota Consulting is a full-service Construction Management, Architectural and Engineering firm headquartered in Waipahu, Hawaii, founded in the 1980s by Brian Bowers and Dexter Kubota. The firm delivers eleven integrated service lines — Construction Management, Architecture, Landscape Architecture, Civil Engineering, Electrical Engineering, Mechanical Engineering, Energy Management, Environmental Consulting, Planning, Project Management, and Interior Design — under a single platform, serving government (state, county, federal) and private sector clients across Hawaii and the Pacific Rim from offices on Oahu, Maui, Kauai, and Hawaii Island. The firm operates as a 100% Employee Stock Ownership Plan (ESOP) since 2012, with over 200 employees and capability depth enhanced through two acquisitions: H&O III (electrical engineering, 2018) and Belt Collins Hawaii (landscape architecture, civil engineering, planning, 2020).

The business model is fee-based professional services: revenue is generated from project-specific contracts, typically structured as cost-plus or fixed-price agreements, secured through competitive bidding for government work and direct engagement/referrals for private clients. The technology stack centers on multi-discipline engineering and design workflows with demonstrated credentials in LEED Gold certified projects (Aualii Warehouse achieving 39% energy reduction and 52% water reduction) and Living Building Challenge pursuit. Project examples span infrastructure (Honouliuli WWTP Secondary Treatment, Hawaiki Submarine Cable Landing Station, Interisland Terminal at Daniel K. Inouye International Airport), education (DOE Ka Hei statewide sustainability program with 81+ PV systems totaling 9.3MW), military (Schofield Barracks Quad B renovation), and commercial (American Savings Bank 373,000 sq ft HQ campus). The firm is ranked #35 nationally on ENR's Top 50 Construction Management Firms (2023) and #59 on the Top 100 PM-for-Fee list.

In 2025, Bowers + Kubota was acquired by Legence (LGN), with the acquisition contributing over $240 million to Legence's Q1 2026 revenue and management citing integration as exceeding expectations, supported by data center demand as a key growth driver. The Bowers brand and leadership are being preserved under the Legence platform, positioning the firm to extend beyond Hawaii into Pacific Rim and broader national infrastructure markets while maintaining its employee-owned cultural foundation.
