North Close Custody Facility Expansion

Historic State Penitentiary Expansion Designed to Revitalise Campus   

The mission of the North Close Custody Facility Expansion was to provide 900+ high security beds at a historic state penitentiary, add additional beds and reorganise and revitalise the campus. HDR and Turner Construction Co. in a joint venture, provided design and construction services for this integrated design-build project.

The finished project achieved the following: 

  • People and product flows were simplified and clarified
  • Staff and land-use efficiency was maximised
  • Energy savings, local construction participation and creative land planning

The project was delivered using the Integrated Project Delivery model within a design-build setting, resulting in a seamless transition from design to construction, providing the owner with a higher level of quality and completeness.

Four buildings in the Washington State Penitentiary North Close Custody expansion project achieved LEED Silver certification:

  • Administration building
  • A core services facility
  • An intensive management/segregation unit
  • Four-unit close-custody housing facility

The North Close Custody expansion received the Best Public Building Award from Northwest Construction magazine.
