Value Engineering Solution
  • Minimising collapsible soils with impact rolling to limit amount of import fill needed on roads and perimeter fence.
  • Integrate stormwater disposal into swales tied into native vegetation to limit stormwater infrastructure and maintenance.

West Kimberley Region Prison is a 150 bed mixed security, mixed gender facility located near the town of Derby. Working in conjunction with the project architects and the Department of Corrective Services Pritchard Francis provided the structural and civil engineering services for the project which has over 45 buildings within a secured perimeter of a campus style site of approximately 25ha. 

The unique security requirements, challenging geotechnical conditions and cyclonic wind loadings are key issues in relation to both civil and structural design elements. 

Native vegetation was used to stabilise natural streams which are required to accommodate the heavy rainfall associated with tropical cyclones and move stormwater away from the site.

Earthworks and pavements have been designed with consideration of locally available materials and the unique behaviour of the foundation materials.
