Mule Creek State Prison Infill Complex

The California Department of Corrections and Rehabilitation’s Mule Creek Infill Complex Project (MCIC) is a design-build project covering approximately 70 acres adjacent to the existing high security Mule Creek State Prison in Ione, California.  The scope of the project included 544,000 square feet of new construction in 23 individual buildings.  The six single-story housing units, each about 40,000 square feet in size, provide housing and support services for 1,584 inmates.  The project achieved a LEED Silver certification.  The MCIC Project was delivered under a design-build contract in order to meet the Project’s aggressive schedule which required that the Project be designed and constructed within a very short 24 months from issuance of Notice to Proceed.

The prime contractor on the MCIC Project was Hensel Phelps Construction Co. from San Jose, California.  The multi-disciplined design team was led by HOK Architects.  The scope of the site infrastructure improvements for the MCIC Project included all on-site and off-site grading, drainage, sanitary sewer collection and disposal, domestic water, fire water, access roads, parking, traffic circulation, perimeter security fence, and support structures located outside the perimeter security fence.  The site grading included cutting 40 feet into a rock hillside and moving over 1 million cubic yards of rock/soil material. The domestic/fire water system included three new 1.3 million gallon water tanks and booster pumps to meet fire suppression demands.

Kjeldsen, Sinnock & Neudeck, Inc. (KSN), provided the civil engineering for all the on-site and off-site infrastructure improvements for the MCIC Project, including grading, drainage, sanitary sewer collection and disposal, domestic and  fire water storage and distribution, gas distribution, access roads, parking, traffic circulation, fencing and concrete hardscape.

KSN worked closely with Hensel-Phelps, HOK Architects and the CDCR Project team during the design phase of the Project to coordinate the scope and schedule of the civil site improvements, and to obtain the approval of the plans and specifications from local and State agencies.  The Notice to Proceed for the project was received in February 2014 and the construction of the project was substantially completed by February 2016.
