DETAILED SCOPE AND DESCRIPTION

ATC Consulting Engineers were involved with Main Roads to embark on a major bridge replacement project that would see effectively a new stronger and wider concrete structure being constructed.

The 78 year old wooden bridge over Lochaber Creek on the Burnett Highway south of Eidsvold was replaced with a 3 x 19m span concrete bridge including:

• Bored Piles using screw in liners
• Construction of columns and headstocks
• Erection of pre-cast deck units
• Construction of deck wearing surface and bridge barrier

During construction a temporary side-track diversion was in place to keep the Burnett Highway moving. As part of the project, a realignment and upgrade to Malmoe Road intersection, just north of the bridge, to provide better visibility when accessing the highway was undertaken.

• Granular widening of existing approaches
• AC and bitumen surfacing
• Extension of existing culverts and installation of temporary culvert under side-track
• Installation of guardrail
• Erosion and sediment control & revegetation

The full scope of ATC Consulting Engineers involvement in the project included:

• Project Management and Delivery
• Contract Administration
• Technical guidance and support to the Principal
• Onsite Engineering supervision
• Review quality data
• Leadership and management of the project
