HONOLULU, Hawaii, November 1, 2022 — Coffman Engineers announced today they have finalized an asset purchase agreement with structural engineering firm Shigemura, Lau, Sakanashi, Higuchi and Associates, Inc. (SLSH). Coffman welcomes SLSH’s four owners and all six staff members to the company. Representatives from both firms finalized the agreement in a signing ceremony on October 31st.

The decision to join Coffman is part of SLSH’s ownership transition plan to provide continued support to their staff and established clients while the ownership plans for retirement. SLSH owners Howard Lau, PE, Craig Sakanashi, PE, Wayne Higuchi, SE, and Beverly Ishii-Nakayama, SE, join Coffman as principal advisors. In addition, all six employees become Coffman employees and move a short distance into Coffman’s Honolulu office. The addition of SLSH expands Coffman’s Honolulu structural group from three to thirteen.

“We were selective and committed to finding the right firm to partner with that would benefit our clients and staff. We were motivated by Coffman’s drive for the same level of client care and attention to detail that our clients have become accustomed to. Our work and values are also complementary. We look forward to bringing our teams together to start a new chapter and to serve our clients with increased resources,” said Howard Lau, SE, Shigemura, Lau, Sakanashi, Higuchi and Associates’ President.

SLSH has provided consulting structural engineering services to private and public clients throughout the Pacific Region for more than 52 years. SLSH’s experience strengthens Coffman’s structural engineering capabilities and complements the company’s other engineering disciplines.

SLSH and Coffman have an ongoing working relationship and share many of the same clients. The two companies’ markets and clients align, particularly in military/DoD, healthcare, housing, and education.
