Hawaii's Best Industrial Construction Company

Clients across the island trust us to provide safe and smooth roads. Whether it’s a large highway or a residential street, we create a risk-free surface for all vehicles. We provide comprehensive roadway services, including asphalt and concrete paving. Because of our location near the center of Maui, we can easily access any project site and efficiently finish the job to minimize traffic detours or delays.

Rojac Construction specializes in the installation and upkeep of underground utilities, such as water, sewer, and drainage lines. Cities throughout Maui count on our engineering crews to repair and maintain municipal pipeline systems, as well as underground electrical and gas lines. We also complete mass earthwork excavation and grading to modify and stabilize the land surface for new development.

For every engineering job, we partner with our sister company, Rojac Trucking, to haul materials to the project site. This approach offers a more convenient and affordable alternative to hiring an external trucking company, and our collaboration saves you the time of searching for a different contractor to transport large construction materials.

Ke AliI Subdivision, 96-lot residential subdivision owned by Towne Realty of Hawaii, included mass earthwork, roadway construction, installation of water, sewer, drainage, electrical, street lighting, telephone, and CATV systems and installation of 110 lineal feet of 11-foot-high by 28-foot-wide precast concrete con-span culvert and 65 lineal feet of double-barrel 8-foot-high by 24-foot-wide con-span culvert with appurtenant inlet and outlet structures. The project was completed in April 2002.
