petrie mill development

Moreton Bay Regional Council

Petrie, Qld

$9.4 million

The Petrie Mill Development is Moreton Bay Regional Council’s redevelopment of the old Petrie Mill; creating a mixed-use development incorporating a university campus alongside residential, commercial and open space land spaces. 


Following our successful completion of early civil works for the project, ALLROADS were awarded the contract to upgrade the Gympie Road Intersection adjacent to this development.


Works involve the intersection upgrade project included: earthworks, stormwater, asphalt placement, water, electrical, Telstra and landscaping.


Careful programming and strategic staging were integral in order to ensure a safe and trafficable site was maintained throughout construction. This was due to the location of the works, combined with a high traffic volume, which resulted in a complex worksite that required the works to be undertaken in five individual stages to ensure minimal disruption to road users.


In addition, a large number of technical challenges and high-risk activities were present on the project requiring careful planning and management. A summary of these challenges and high-risk activities are as follows:

  • Complex service relocations,

  • Varying pavements designs,

  • No long term/daytime lane closures on Gympie Road,

  • Multiple trenchless service road crossings in close proximity to existing live services.


A well thought out methodology in conjunction with ALLROADS’ effective and innovative project and QHSE management approach enabled these challenges to be overcome and for the successful delivery of this project.

  • Supply, placement, conditioning and compaction of 18,500m3 of class A1 Fill Material


  • Multiple service crossings under Gympie Road using HDD and Pipe Jacking techniques


  • Monitoring and protection of Cultural Heritage landmarks and structures during construction


  • Multiple traffic switches


  • Supply, placement and compaction of 7,300 tonnes of Dense Graded Asphalt


  • Effective partnering with Moreton Bay Regional Council


  • Regular internal and external QHSE audits conducted to ensure high standards maintained
