Group 70 International

What Group 70 International does

Group 70 International, Inc. is a privately held, multi-disciplinary architecture, engineering, and planning firm headquartered in Honolulu, Hawaii, founded circa 1971 by Francis S. Oda, D.Arch, FAIA. The firm delivers integrated professional services across four core disciplines—Architecture, Civil Engineering, Interior Design, and Planning & Environment—serving clients in hospitality and resort development, education (K-12 and university), government and public sector, healthcare, commercial, and residential sectors primarily in Hawaii and the Pacific, with international project work in Japan, Indonesia, Tahiti, and Senegal.

The firm employs between 101 and 250 staff organized across an extensive seniority hierarchy (Executive Suite, Principals, Of Counsel, Associate Principals, Senior Associates, Associates, Doctorates, LEED AP staff). Its technical toolkit includes BIM and Revit 360 for 3D design delivery, Bluebeam Studio for collaborative reviews, and GIS applications for natural resource management and entitlements. The firm is differentiated by a LEED-compliant sustainability methodology integrated into all projects, a "Hawaiian Sense of Place" design approach deeply embedded in cultural and community context, and one of the few Hawaii-based planning practices offering natural resource management and preservation services. It maintains a G70 Foundation as a nonprofit affiliated entity and pursues ongoing community engagement (Canstruction, Habitat for Humanity, Trust for Public Land).

G70 generates revenue through project-based professional services fees—architectural design, civil engineering, interior design, planning, entitlements, and environmental consulting—charged on a project-by-project basis. It acquires clients via direct enterprise engagement, formal government procurement (RFP/RFQ), and reputation-driven referrals across a portfolio that includes marquee relationships with Kamehameha Schools, Iolani School, University of Hawaii, Hilton, Marriott, Hyatt, Four Seasons, Halekulani, DoDEA, City & County of Honolulu, and DHHL. Following the founder's passing in February 2026, leadership transitioned to CEO Linda C. Miki, President Kawika McKeague, COO Ryan Char, and CFO Rachel Takiguchi. Revenue figures are not publicly disclosed.
