    Brief

    The existing roof covering at R55 Target Station 1 has reached the end of its serviceable life and is experiencing recurring water ingress that threatens scientific operations, equipment, and facility continuity. The current 1960s Flintkote Monoform roofing system shows widespread deterioration, with saturated insulation in the southern gutter area presenting immediate operational risks. This project requires refurbishment of approximately 4,800m² of roof covering through installation of a new overlay roofing system with high-reflectivity finish to reduce thermal loading, along with localised replacement of failed insulation and necessary alterations to roof-mounted services and lightning protection systems. The work must be completed within an operational scientific facility, requiring careful coordination with building users, existing plant, equipment, and lightning protection infrastructure. Suppliers should note that thermal upgrades are not feasible due to existing roof construction constraints, and the solution prioritises delivering a long-life waterproofing system while maintaining compatibility with active facility operations.
