Margate and Cox Street Drainage Upgrade

Margate and Cox Street, Recliffe
The Project

Moreton Bay Shire Council engaged CES Civil as principal contractor to upgrade drainage lines down Mabel Street across Margate Parade with an upgrade to the outlet to Moreton Bay as part of Stage 1 of the overall stormwater project. Stage 1 also included ancillary stormwater infrastructure and inlets to capture surface flows, from the connecting upstream stormwater infrastructure. The project included key items such as - Ocean outfall constructed on 750mm diameter pile to carry the 3 x 1400mm diameter ocean outfall discharge pipes - Supply and Installation of a Gross pollutant trap with an excavation depth exceeding 8 meters - Design and construction of special pre cast stormwater pits. The largest pre cast pit element was approx 100-ton reduced by 60% of its initial weight through review of the design and geotechnical conditions. Pre cast pits were used over cast insitu structures to expedite the onsite construction time due to the sensitivity of the location near the Redcliffe esplanade and local primary school.
