Construction of 6 major rail, road creek DN1500 under bores to allow for the installation of DN1290 Sintakote water mains. Associated civil and mechanical works including deep shaft construction via caisson techniques. 1.9km of trench excavation, welding and installation of DN1290 Sintakote water mains.
Construction of 5.1km of DN900 and DN1200 gravity sewer primarily via microtunnelling, construction of deep shafts and concrete caissons, construction of concrete manholes and multiple live sewer connections.
Construction of infill sewerage infrastructure using conventional open excavation methods as well as specialised trenchless techniques.
Construction of pipelines, maintenance shafts, maintenance holes and pump stations. Responsible for decommissioning, live sewer and commissioning works and railway lines.
Construction of one line of 170m of DN1800, multiple sewer, water and telco diversions, multiple pedestrian and road reconstructions within shopping precincts as well as removal and replacement of existing drainage infrastructure by conventional trencching techniques. The works also involve a major highway crossing as well as management and coordination for several infrastructure authorities.
Construction of 790m of DN1200 and 820m of DN1400 gravity sewer at grades as low os 0.1%. Construction of deep shafts, concrete caissons, construction of concrete manholes. Other works included construction of a valve chamber, minor open trenching works, mechanical fitting installation and multiple live connections works.
