As the Australian Government advances plans for a high-speed rail link between Sydney and Newcastle, industry group Cement, Concrete & Aggregates Australia (CCAA) said the move highlights the urgent need for coordinated planning of heavy construction materials to keep infrastructure projects on schedule and within budget.
CCAA chief executive officer Michael Kilgariff said the announcement of the development phase of the Newcastle – Sydney high-speed rail project has underscored the importance of a comprehensive Heavy Construction Materials Plan for New South Wales.
“For a project the scale of High Speed Rail, with extensive civil works, structures, stations and supporting infrastructure, understanding future materials demand and existing supply capacity is fundamental to managing cost pressures and maintaining construction timeframes,” Kilgariff said.
“Between now and 2036, at least 500 million tonnes of finished quarry products will be required to supply the Greater Sydney region alone, highlighting the scale of materials required across concurrent public and private projects.”
The government recently committed a further $229.6 million to the rail project’s development phase, bringing total funding to nearly $660 million to prepare detailed designs, approvals and cost estimates ahead of full construction, expected to be “shovel-ready” within two years.
Kilgariff warned that without a clear, coordinated materials strategy, large projects like high-speed rail risk facing supply bottlenecks and cost pressures. CCAA has called for an integrated NSW Heavy Construction Materials Plan backed by rigorous supply and demand analysis, which would help quantify future requirements, map production capacity and identify freight and logistics risks early in the planning cycle.
“CCAA has consistently called for an integrated NSW Heavy Construction Materials Plan to provide reliable, affordable and predictable supply,” Kilgariff said.
“Such a plan should be underpinned by a detailed supply and demand study that quantifies future materials requirements, assesses production capacity and freight corridors, and identifies risks early in the project lifecycle.
“With multiple major projects progressing simultaneously, materials planning cannot be an afterthought.
“A comprehensive evidence base will help align Commonwealth infrastructure ambition with State resource settings, reducing risk, limiting budgetary pressures, and supporting the timely delivery of High Speed Rail and other critical projects.”
The industry group also highlighted that concurrent public and private sector projects will compete for the same materials and resources, making proactive engagement between government and industry critical.
CCAA represents Australia’s heavy construction materials sector, which generates more than $15 billion annually and supports tens of thousands of jobs, supplying the bulk of the nation’s cement, concrete and aggregates.
