Our precast operation was established in 1966 under the Dillingham Corporation. The original facility was located on a few acres of land near Kokea Street in downtown Honolulu. In 1973, the precast operation was relocated to Campbell Industrial Park in Leeward West Oahu. In the summer of 2001, Grace Pacific LLC acquired the precast operation from Dillingham Corporation.
In 2006, Grace Pacific Precast, Inc. and Rocky Mountain Prestress merged to form GPRM Prestress, LLC. This partnership allowed the two companies to combine their strengths and abilities to provide the best product and service to the Hawaii construction market.
GPRM Prestress is a member of the Precast / Prestressed Concrete Institute and is a certified plant under the PCI Certification Program. The Council of American Building Officials (CABO) recognizes PCI as an approved quality assurance inspection agency. Mandatory compliance to nationally recognized standards is necessary to attain and hold "Certified Plant" status.
