Current Projects

Building Queensland leads the development of Detailed Business Cases where potential government investment exceeds $100 million. Proposals currently being developed by Building Queensland include:


Department of Justice and Attorney-General

Building Queensland is investigating options for the expansion of the Arthur Gorrie Correctional Centre located in Wacol, a high security remand facility for male prisoners in Southern Queensland. It currently provides 890 high security cells for prisoners in remand. The Business Case will assess the construction of 628 additional cells to meet growth in remand prisoner numbers across Queensland’s corrective services system.



Building Queensland is leading the Detailed Business Case for the Burdekin Falls Dam - Saddle Dam & Monolith Improvement Project to investigate options for improvement works so the dam continues to meet current best practice standards. Since its construction in 1987, there have been changes to dam safety standards and hydrological information, and the dam needs improving to reflect these changes.


SunWater and the Gladstone Area Water Board

Building Queensland is leading the development of a Business Case for the Lower Fitzroy River Infrastructure Project. The components of the Lower Fitzroy River Infrastructure Project comprise construction and operation of Rookwood Weir, and upgrades to and construction of roads and bridges and associated infrastructure. The proposed weir infrastructure will operate in concert with the existing Fitzroy Barrage located in Rockhampton.


Department of Science, Information Technology and Innovation

Building Queensland is leading the development of the Business Case for improving radio communications for Queensland’s Public Safety Agencies in regional Queensland. The Public Safety Regional Radio Communications Business Case will assess enhanced digital radio voice and narrow band data communications in regional Queensland.


Department of Transport and Main Roads

Building Queensland is leading the development of the Detailed Business Case for the Townsville Eastern Access Rail Corridor (TEARC), a proposed new freight rail link connecting the Mount Isa Line and North Coast Line, through the Townsville State Development Area to the Port of Townsville. The project is expected to meet future demand and improve efficiencies.


Completed Projects

The following Detailed Business Cases have been finalised and Building Queensland’s role is complete. These projects are now with the Queensland Government to progress.

Nullinga Dam

Department of Energy and Water Supply

The proposed Nullinga Dam site is located on the Walsh River in the Atherton Tablelands. Initially, Nullinga Dam was proposed as a future water supply to serve growing urban demand in Cairns and to stimulate irrigated agriculture in the region, by supplementing existing supplies.

The Preliminary Business Case investigated the potential for Nullinga Dam and other options to address the identified future water supply shortfall in the region. The scope of work included water demand assessments, preliminary analysis of costs, risks and benefits, consultation with key stakeholders and recommendations for preferred options.

Building Queensland completed the Preliminary Business Case for Nullinga Dam and Other Options in Q2 2017 and provided it to the Department of Energy and Water Supply. The Nullinga Dam and Other Options Preliminary Business Case is one of many studies that are being undertaken as part of the National Water Infrastructure Development Fund.


Smithfield Transport Corridor Upgrade

Department of Transport and Main Roads

Building Queensland completed the Detailed Business Case for the Smithfield Transport Corridor Upgrade Project in Q2 2017. The Detailed Business Case was returned to the Department of Transport and Main Roads to progress.

The project is a proposed new 3.8-kilometre road bypass to the east of the Captain Cook Highway between Yorkeys Knob Road roundabout and McGregor Road roundabout north of Cairns.


Cross River Rail

Department of Transport and Main Roads

Building Queensland led the development of the Cross River Rail Detailed Business Case, providing rigorous and thorough investigation throughout the process, while working collaboratively with the Department of Transport and Main Roads.

After completion of the June 2016 Business Case the project transitioned to Department of Transport and Main Roads for implementation. Since then the Queensland Government has established the Cross River Rail Delivery Authority, which is tasked with leading the further development, procurement and delivery of the project.

Cross River Rail Business Case


Beerburrum to Nambour Rail Upgrade Project

Department of Transport and Main Roads

Building Queensland presented the completed Detailed Business Case to The Department of Transport and Main Roads in December 2016. The Business Case investigated duplication of the North Coast Rail Line on an improved alignment between Beerburrum and Landsborough and other upgrades to Nambour. This section of the North Coast Line is approximately 40 kilometres in length and consists of a single bi-directional line, with passing loops at stations only.


European Train Control System (ETCS)—Inner City

Department of Transport and Main Roads; Queensland Rail

Building Queensland finalised its first Business Case for ETCS - Inner City and presented it to government in May 2016. The Queensland Government subsequently committed full funding of $634.3 million to the project over the next eight years as part of its 2016–17 Budget commitments. Based on an existing European model, the project consists of an in-cab signaling control and automatic train protection system that guards against train collisions and over-speed derailment. The ETCS - Inner City project will also benefit Cross River Rail.
