The project also includes associated works such as two ventilation stations and outlets and a tollroad control centre (TCC). LW was declared to be a significant project under section 26(1)(a) of the State Development and Public Works Organisation Act 1971 (the SDPWO Act) on 2 November 2007. Following consideration of the project’s environmental impact statement (EIS) and comments made on the EIS by members of the public, stakeholders and government agencies, the Coordinator-General’s report evaluating the EIS was completed on 23 April 2010. The report found that the project could proceed, subject to compliance with conditions and recommendations made by the Coordinator-General to mitigate project impacts. The report noted that the proponent had not yet chosen its construction contractor, but that the successful tenderer would be responsible for the project’s detailed design. Accordingly, any amendments to the reference design (RD) assessed during the EIS process would likely require a Coordinator-General’s project change report, prepared under Part 4, Division 3A of the SDPWO Act. On 25 October 2010, the proponent provided the Department of Infrastructure and Planning (DIP) with an application for project changes (APC) as per section 35C of the Act. The application requested the Coordinator-General assess proposed design and delivery changes. On 30 October 2010, the Department of Infrastructure and Planning (DIP) advertised a request for submissions from the public on the project changes, with submissions invited until 19 November 2010. On 29 November 2010 Brisbane City Council (BCC) supplied the Coordinator- General with further information on the project changes (FIAPC) in a document that responded to key issues raised in submissions. This document, the Coordinator-General’s report on the Legacy Way project changes, provides the Coordinator-General’s decision on the project changes. The assessment has been made having regard to the SDPWO Act, the APC, the FIAPC, discussion and correspondence between the proponent and DIP, the EIS, public 1 The project was re-named by the Lord Mayor on 10 November 2010, with a pledge to provide part of toll charges to support Legacy. The Legacy Way Project (formerly known as Northern Link Road Tunnel) Coordinator-General’s report on project changes - 5 - submissions and comment, input received from government agencies on the changes, and an independent review of the alignment changes undertaken by Parsons Brinckerhoff. 1.2 The proponent The project proponent is Brisbane City Council (BCC). On 20 September 2010, BCC selected a preferred contractor for the design, construction, operation and maintenance of the project. The contractor is Transcity Joint Venture (Transcity), which includes the Spanish infrastructure company, Acciona, Australian construction firm, BMD Constructions, and Italian tunnelling experts, Ghella. Transcity has been contracted to deliver and operate the project as BCC’s agent for a 10-year period. The Legacy Way Project (formerly known as Northern Link Road Tunnel) - 6 - Coordinator-General’s report on project changes 2 Description of proposed changes As part of its winning bid, Transcity proposed various changes to the project’s RD related to design and delivery methods. Its rationale was to increase project efficiencies while working to reduce the cost of public-funded infrastructure. The tendered design is substantially the same as the RD and is consistent with the original project’s objectives. Following is an overview of the key project changes proposed by Transcity in the APC. Section 4: Evaluation of environmental effects, provides an assessment of the changes. 2.1 Construction method changes For the tunnels, the key construction method has changed. Both tunnels
