Bupa Aged Care Facility Mosman

An aged care facility at Mosman was suffering from an onsite detention system that did not work properly. After a detailed assessment by Stormwater Sydney, our men found that the cast in place structure still constrained the formwork in place. The pipework was also at the wrong level and orifice places and not been previously set up. After three days, we had the system operating as designed and compliant with the Council’s regulations.
