Head House Roof Slab Major Milestone Achieved

The successful completion of the Head House roof slab marks a significant milestone in the delivery of this complex structure, constructed alongside an operational railway line.

The 1,250 m² reinforced concrete Head House has been built within a highly constrained environment, requiring detailed planning, technical expertise and close collaboration across the project team. The structure features a 1 m-thick base slab, vertical elements reaching up to 8.5 m in height, and a 350 mm-thick roof slab, supported by an extensive temporary works arrangement throughout construction.

The project involved approximately 985 tonnes of steel reinforcement and complex lifting operations using two tower cranes to support the installation of formwork and structural elements.

Working in close proximity to live railway operations presented significant logistical and engineering challenges. Through careful planning, effective coordination and a strong commitment to safety, the team successfully overcame these constraints to achieve this important milestone.

Completion of the roof slab enables the next phase of construction to progress, including steel frame installation and internal and external fit-out works.

This achievement is a testament to the dedication, expertise and teamwork of everyone involved and represents another important step towards the successful delivery of the Head House.
