The works comprise design and delivery of redevelopment investment at Irwin Barracks (including works to relevant services), and provision of working and living accommodation at Irwin to accommodate elements relocating from Leeuwin Barracks.

The Managing Contractor services include delivery of design (through 5%, 30%, 50%, 90% and final design stages), assistance in siting board and project approvals, procurement of design subconsultants and trade packages, and management of the following and related works to redevelop Irwin Barracks and provide facilities for those Leeuwin Barracks agencies relocated (consolidated) into Irwin Barracks, within budget:
• on-site consultation and coordination for design and for construction activity with resident (or proposed resident) Agencies, and other key stakeholders including CIOG;
• assembly of asset assessment, contamination survey and disposal, master planning (in accordance with Irwin Zone Plan), indicative construction program, likelihood of overflow storage works into Palmer Barracks, and initial concepts and costings to facilitate scope definition within budget constraints;
• GDL and data assembly for GEMS, with GDL shells completed before or during the 90% design stage;
• demolition of facilities and infrastructure that is inconsistent with the required redevelopment/ consolidation scope or other use;
• upgrade of relevant existing services and in-ground infrastructure, the capacity to provide for the increased Leeuwin dependency demand;
• upgrade and refurbishment of relevant existing facilities, including working accommodation, physical fitness facilities, base access, headquarters buildings and training facilities;
• new facilities, including those required to replace existing facilities and to accommodate the increased dependency;
• new services and in-ground infrastructure, including those required to replace existing services/infrastructure and to accommodate the increased dependency of additional personnel; and
• office removal services to relocate Leeuwin dependencies to Irwin Barracks.
The works are to meet Irwin Barracks’ area sustainment and operational support capabilities, taking into account the expected dependency increase arising from the Leeuwin personnel and need to avoid disruption.
