Mount Lindesay Highway Upgrade:
Camp Cable to Tamborine Street

The scope of work for this project included:

• 3-span bridge with cast in-situ deck inclusive of cast in place piles with steel liners and Fabricated Steel Safety Barrier
• embankment construction
• pavement construction (unbound, plant mixed foam bitumen (PMFB) and Asphalt
• modification of existing signals
• street lighting
• shotcreting
• retaining wall and ground retention
• fencing
• electrical and ITS
• guardrail and concrete barrier installation.

• Piling – Significant temporary works required to establish pile platforms adjacent to an operational highway and high voltage power lines. The piling platforms needed to be increased in capacity and size to facilitate the installation of the bridge pier piles located within the existing waterway footprint.
• Piers – Pier construction columns extended from the pier piles; the columns extended up to the underside of the pier Headstock. The falsework and formwork to construct the pier headstocks considered this bracing allowance for the columns and the associated forms required to form and cast the pier headstocks.
• Bridge Decks – The bridge decks needed to be installed at night so as not to undertake a high-risk activity under an operational highway. Traffic was held during each unloading operation of the bridge decks. Undertaking bridge deck installation is a high-risk activity this work also included understanding the traffic risks and also working at night. The centre span was also installed as a dual lift requiring another level of detailed planning to undertake the operation.
• Plant Mixed Foam Bitumen (PMFB) – The supply and installation of PMFB is new to the industry for both subcontractors, contractors and DTMR. This project was one of the first along the MLH to be installed. There has been a lot of development for all parties to understand how to work with PMFB. understanding supply and installation constraints along with the necessary quality requirements to meet the specification.
