Mule Creek

Challenge Design-Build Project Delivery Addressed

The choice of design-build delivery played a crucial role throughout design and construction. The California Department of Corrections and Rehabilitation’s mission statement is to create a secure, safe and rehabilitative facility. The mission statement was their primary guide. The second objective was to build a facility focused on value, ease of maintenance and durability. Through the use of the design-build delivery method, the team was able to successfully support the mission and achieve the secondary objectives. The team partnered and worked together to develop cost effective solutions; improve the design as it developed; and built a low-maintenance, durable facility.


The Mule Creek Infill Complex project was a fast-paced, 90-acre, 23-building, $373 million design-build project constructed in partnership with the California Department of Corrections and Rehabilitation (CDCR) as the owner and HOK as the primary designer. This exceptional project was delivered in under two years, which was two months ahead of schedule. With sustainability as a primary goal, the project achieved four (4) silver certifications and one (1) gold certification over the various building types.
