Kewalo Basin Harbor Improvements

Kewalo Basin Harbor has been significant to the Honolulu area for centuries and was once known as the Hawaiian fishery of Kukuluae’o. In 1913 the harbor was sold to the territory of Hawaii from the Ward family. Since that time the active harbor had fallen into disrepair and was in need of upgrades.

As part of the Ward Village vision to create a vibrant urban community, Coffman was hired by the operator and manager of Kewalo Harbor, Howard Hughes Corporation, for a $23 M facility upgrade of the active commercial small boat harbor. Coffman served as the designer of record and provided civil, structural, mechanical, and electrical engineering design for the renovation and upgrades.

The project increased the number of boat slips by 35 to 184 and included the replacement of the plumbing, electrical, and superstructure for Pier A, B, C, D, the Loading Dock, and half of the Front Row. Work also included new fuel tanks and fueling station, piles for Pier C finger piers, water and electrical service for Fisherman’s Wharf, security gates, WiFi, CCTV, repairs to the bulkhead wall, Herringbone Pier, and half of the Front Row Piers and a finger pier at Pier D. Sea Engineering was the lead contractor and Coffman provided the schematic through final design and engineering assistance throughout construction while maintaining an operational harbor.
