Message from the President

Hafa Adai!

I welcome you to Hawaiian Rock Products (HRP), the largest producer of limestone aggregate based building materials and the largest asphalt paving contractor in Guam, and Northern Marianas Islands.

Hawaiian Rock Products (HRP) was formed by our founding parent company, Dillingham Corporation, to perform a contract for asphalt paving on the runways and taxiways at Andersen AFB. In August 1965, our main quarry property at Fadian Guam was leased from the Bamba Family. Today, asphalt paving remains the core part of our business; however HRP has expanded into aggregates sales, Ready-mix Concrete, Hollow Block, Concrete Pipe, Paver Blocks, Pre-Cast Manholes and Retaining Wall System (Keystone) Supplies.

In 1988, we re-established our operations in Saipan, producing Quarry Products, Ready Mix Concrete and performing Asphalt Paving from our Obyan quarry location, In 1991, a partnership was formed with the owners of FPA Pacific – who produce Quarry Products and Ready Mix Concrete. HRP also has an asphalt plant on Tinian.

In August 1990, HRP was purchased by Mitsubishi Cement Corporation Development (MCCD) and Mitsubishi Corporation (MC). MCCD has provided us with tremendous support to develop and expand HRP to meet the needs of the Construction industry in Guam and CNMI.

We are continuously developing new innovative ways of providing our products with the highest quality and most reasonable price that is technologically available. For the past 10 years, HRP has invested in increasing our production capacity to support the upcoming private and military relocation projects.

HRP projects are built by a team of hardworking laborers, technicians, specialists and craftsmen – a workforce with the experience to take on the most difficult projects. We believe that safety, quality and service are the most integral components of our business. Proudly, these same people help build and support our Guam community.

Thank you to all past and present employees for your loyal service and dedicated work over the past 65 years. Thank you to all our suppliers for your tremendous support and to our customers for trusting us with your construction need. Here to our 65 YEARS of providing the “best” – and here’s to the next 65 years to come!

Sincerely

Jerrold C. Johnson
President, Hawaiian Rock Products
