Derby Street Upgrade
Derby Street South: Before & After Construction
Derby Street North: Before & After Construction
Project Summary
CWC delivered the pre-construction design, environmental services and construction management for the upgrading of two key sections of Derby Street in Walcha, the primary gateway from the south and north into the regional NSW North Tablelands township.
The project involved significant collaboration with Walcha Council and the community to achieve a practical, affordable outcome with the planned upgrade works that will serve to enhance the safety, amenity and character of Walcha.
Services provided included detail survey, geotechnical investigations, detail design development for the road upgrade including watermain relocation design, stormwater assessment/design, landscape design, utility relocation design coordination, the preparation of environmental approvals (REF), construction tender documentation and managing the construction tender phase for the first phase of works.
The Derby Street upgrade project involved a challenging balance of competing engineering technical requirements and community expectations against overall budget availability. CWC worked closely with Council to develop and refine the design efficiently to ensure each of these items were considered, adding significant value to the process.
Construction of the first phase of delivery commenced in late 2024, with completion of works achieved in May 2025. As part of CWC’s end-to-end service, we provided construction supervision & contract administration lead (as Principal’s Authorised Person) for Council.
