Executive Summary
Methodology
Stage 1:
Design management, traffic staging, temporary pavements, and service
relocations.
To construct the new intersection, significant traffic engineering was completed to optimise the project costs, delivery, and minimisation to the VicRoads networks, especially the heavy vehicles which utilised the road as a primary route to access the industrial areas.
Gearon Civil engaged, and guided traffic engineers to complete traffic counts, traffic
impact assessments, SCATs modifications options, temporary pavement designs and
temporary barrier/staging plans.
This work fed into significant planning and consultation with the DoT project team prior
to any works commenced on site, or any MOAs were applied for, and granted.
Further design management was undertaken to change materials and methodologies to
utilise trenchless technologies.
Once approvals and designs were finalised, works under lane closures commenced
during both day & night works, to complete temporary pavement widenings, service relocations, barrier installation and temporary construction line markings.
Stage 2: Delivery
Following the installation of barriers, all full-depth pavement, subgrade remediation, drainage and electrical works were was able to be safely constructed behind barriers, eliminating the hazards around working with live traffic.
Traffic barriers were on nightshift under full road closures multiple times to facilitate construction access to all area’s required, whilst always maintaining one lane in each direction for traffic during the day.
