Freyssinet was engaged to refurbish the XXXX Castlemaine Brewery trade waste sump, enhancing its corrosion resistance against the acidic byproducts of beer production. The scope included the installation of a BluSeal Anchor Knob system,
concrete remediation, steel replacement, and modular formwork installation.
A key challenge of the project was navigating the confined space, with all personnel and materials, including modular formwork, accessed through a single manhole. This constraint demanded meticulous planning, precise coordination, and specialist confined space expertise.
