Mirrabooka Avenue reaches Practical Completion


Porter Consulting Engineers were commissioned by the City of Wanneroo to provide detailed engineering design plans, documentation and construction administration to allow the City to proceed with road upgrade to a median-divided dual carriageway of Mirrabooka Avenue from Hepburn Avenue to Gnangara Road including all interconnecting intersections.

Upgrading of the road network was identified to meet the additional transport demand generated by ongoing land development in Landsdale, Kingsway and Darch.

Constraints include underground and above ground services conflicts, tie-in with existing road carriageways, intersections and verge/property levels to minimise interface issues. Achieving adequate Clear Zones on carriageways and sightlines at intersections and pedestrian road crossings. Negotiation with service authorities on relocations, adjustments and modifications while aiming to achieve timeline and budget constraints.

The project involved detailed initial liaison with service authorities over relocation or protection of major services including, trunk water mains, optic fibre cable and pits and street lighting. Early engagement with these stakeholders enabled works to be undertaken prior to road construction works commencing.

PCE were commissioned to manage the project which includes management of all sub-consultants as well as the provision of a design report. The project was completed in September 2018.
