Project No: 6658 & 6515
The BEC Team contributed through a range of disciplines to this two-storey duplex project in Burwah. Our structural contribution covered foundation, framing, bracing, and roof structure right through to construction support and form 16 certification. We also provided Hydraulic plumbing and drainage, reticulation and rainwater drainage for the project. Our civil contribution included water and sewer connections, bulk earthworks plan, erosion and sediment control plan, storm-water drainage, vehicle crossover and submission of applications and approval paperwork. After our initial scope was completed, we were re-engaged by the client to provide design and certification for a relocated property sewer connection for inclusion in a build over asset application to Unity Water.
The storm-water for this project was particularly challenging. The site is sloped downward from the road, and current standards require that site runoff drains to the kerb; this issue was further complicated as the site captured upstream storm-water run-off from the neighbouring property in addition to its own. After building up what we could of the property, our storm-water team designed a charged system, utilizing a u-bend like system to deliver water from the lower ground back up to kerb level, with an additional infiltration type ‘cleaning eye’ pit and soaking bed, which would prevent stagnant water from sitting in the system. Additionally, our team designed a rock garden which doubled as a retention tank for slow release of storm-water flow.
