LOCAL PEOPLE. LASTING IMPACT.
Precast expertise.
Island roots.
GPRM Prestress designs, manufactures and delivers precast and prestressed concrete for projects throughout the Hawaiian Islands. Our products serve structural, architectural and civil building markets.
Local manufacturing. Project support.
From our plant in Campbell Industrial Park, Kapolei, we help teams plan the use of precast components and coordinate product designs, details and delivery.
Our plant is PCI certified. As an AltusGroup precaster, GPRM also produces CarbonCast products.
A foundation built over generations.
Our history reaches back to Rocky Mountain Prestress, founded in Denver in 1958, and the establishment of the Dillingham facility on Oʻahu in 1966. Our current Kapolei facility was established in 1973.
