San Quentin State Prison was opened in July 1852 and covers 432
acres. San Quentin housed both male and female inmates until 1933
when the women's prison at Tehachapi was built.
The Department of Corrections selected GHD to provide
professional engineering services for a new 1,000-bed condemned
inmate complex adjacent to the existing San Quentin main facility.
We were selected because of our unique ability to provide all of
the required engineering disciplines for the project in-house. The
complex will be located on approximately 35 acres at Dairy Hill.
Grading of the site will require the movement of approximately
180,000 cubic yards of soil and demolition of 39 buildings. An
additional third housing unit may be required at a later date to
accommodate additional inmates.
