Honolulu, Hawaii


The project is the redevelopment of Block ‘F’ bordered by Ala Moana Boulevard, Coral Street, Keawe Street, and Auahi Street in the Kaka‘ako district in Honolulu. The project is a portion of Kamehameha Schools’ Kaialulu ‘o Kaka’ako Master Plan to revitalize the area.

The project includes the renovation of six existing structures and construction of two new buildings to create commercial spaces.  Existing structures renovated included a two-story concrete building, a one-story pre-engineered metal building, and two two-story steel quonset huts.  The total building area is approximately 82,000 SF.  A new seven-story, 269-stall parking structure was also constructed.

Client Benefits

Reviewed multiple structural alternates in an attempt to provide the client with the most economical structural systems.  For example, our office considered precast concrete, cast-in-place concrete and structural steel for the parking structure.  We also provided preliminary foundation designs using precast concrete driven piles, cast-in-place drilled shafts and a concrete mat.  Because of the extremely tight site conditions, a precast concrete structure with precast concrete piles was most cost-effective and constructible.       

In order to retain much of the existing buildings on the site, we made numerous site visits to determine existing conditions.  We also recommended material testing in some locations to determine as-built conditions and minimize overly conservative design assumptions.  Existing steel beams supporting a wood floor were reused to support a composite metal deck with concrete topping.  Weld bend tests on the existing steel beams were conducted to determine the appropriate welding procedure for the older steel sections.      

The Science and Design of Structural Engineering

In order to maximize allowable building area within Hawaii Community Development Authority rules, the majority of the existing buildings needed to be reused.  This presented a unique structural challenge, since many of the existing quonset hut buildings do not meet current structural building code requirements.  We worked closely with the architect, developer and building department to develop a cost effective way to structurally address all code compliance issues and still retain a significant portion of the existing structural framing.
