Transport Infrastructure Contract – Target Project Cost (TIC-TPC) Showcase
Transport Infrastructure Contract – Target Project Cost (TIC-TPC) is a new contract which has been developed to collaboratively engage suppliers in a formal tendering process with urgency to award and act on delivering the project on the ground. The TPC’s delivery model is design and construct and is suited for projects with low to medium complexity […]
Concrete Pavement Fracturing Construction at M1 Pacific Motorway (Varsity Lakes to Tugun)
Approximately 10.0 km of motorway concrete pavements (two lane carriageway each side) between Varsity Lakes and Tugun have reached the end of the design life and require reconstruction upgrades to keep this section of Pacific Motorway in a serviceable condition. Considering carbon emission, environmental factors, and cost benefits, the project adopted the reconstruction option of […]
Applying Flood Data to Inform Highway Upgrade Prioritisations
When upgrading highways, flood estimations typically concentrate on providing a defined maximum probability of flooding (flood immunity) and times of closure at specific crossings (bridges, culverts, floodways). This approach is based on location and assumes hydraulic independence between structures or floodplains. Highway closure due to flooding is important when planning highway upgrades. The level of […]
Application Of Artificial Intelligence(Ai) For The Effectiveness And Risk Mitigation In Contract Administration
Efficient contract management is critical to project success. To minimise project failures, advanced digital technologies are suggested for contract administration, but they have yielded little success in practice. Therefore, this study evaluates the potential of Artificial Intelligence (AI) to fulfil the roles and responsibilities of contract administrator. A systematic literature review has been used to […]
Road Drainage Manual harmonised with Austroads Guide
Previously, Transport and Main Roads (TMR) relied on the Road Drainage Manual (RDM), which was the longstanding standalone manual for planning, designing, operating, and maintaining road drainage infrastructure. However, recognising the need for alignment with national standards, we have harmonised the RDM with the recently released version of the Austroads Guide to Road Design (AGRD) […]
The new ARR Climate Change Guidance – Impacts on Design Floods in Queensland and Implications for Infrastructure Projects
The original Australian Rainfall and Runoff (ARR – 2016) climate change guidance recommended increasing rainfall design events (rainfall intensity) in the typical range of 10-20% to allow for the impact of climate change to the year 2100. This guidance assumed the increase was not a function of event AEP or duration, but only a function […]
Operational viability of a deteriorating bridge – structural assessment based on Engineering Policy 171
This is a case study about two 43-year-old deteriorating bridges on the national land transport network serving as critical link access to port facilitating trade and economic development in the region. Bridges are designed under the 1976 NAASRA standards for T44 design class. In 2019, severe cracking reported in pre-stressed concrete underwater piles, one of […]
Flood Loadings on Bridges – Is it time to bring Computational Fluid Dynamics into the equation?
TMR’s Hydraulics and Flooding Unit has successfully applied Computational Fluid Dynamics (CFD) since 2016 and has a stand-alone licence for the CFD package FLOW-3D. Currently FLOW-3D is mostly used in the Department to validate empirical form loss coefficients at bridge and culvert structures in commonly used 2-dimensional hydraulic models like TUFLOW, thus reducing modelling uncertainty […]
Two projects, one bridge. Maintenance and Planning working collaboratively toward a shared outcome
In 2020, significant structural deficiencies were identified on the Barron River bridge in Kuranda due to use of what is now referred to as “brittle steel” during the 1960s construction. An initial investigation was undertaken to understand the present risk associated with the structure and its operational loading. This period involved significant load restrictions and […]
Bruce Hwy – Six Mile Creek to Gavial Creek Pavement Widening and Rehabilitation
The Bruce Hwy – Six Mile Creek to Gavial Creek Pavement Widening and Rehabilitation Project stands as a comprehensive endeavour, addressing the widening and rehabilitation needs of over 12km of the Bruce Hwy. The project entails the construction of a Foamed Bitumen in situ stabilized base over a triple blend stabilized subbase, strategically optimizing the […]
