About Us

The H. C. Olsen Construction Company has performed general contracting services in a variety of settings since 1946.

While its mainstay has always been telecommunications work for the major telecom providers, Olsen Construction has continued to grow over the years and has expanded its base to include major higher education and commercial clients in Southern California.

Olsen Construction presently specializes in projects involving: 1) new construction; 2) alterations to existing buildings, building systems, and interior spaces; and 3) major hardscape/landscape improvements. Olsen has also been involved from the earliest days with wireless telecommunications, and has a group solely dedicated to the installation and upgrading of cellular antennas and sites.

Olsen Construction is proud to be a union contractor (signatory with the Laborers and Carpenters unions) and a Public Utilities-Certified Hispanic-American/Woman-Owned and Operated Business.

Olsen Construction is licensed in California, Nevada, and Arizona.
