We were Contractor Designer for temporary work design of this Contract. Our services include temporary works design, including ELS, temporary slope and temporary support for the construction of three footbridges, one subway, landscaped walkway and water feature park. Two of the footbridges are located at Lung Cheung Road and the remaining footbridge and the subway are located at Choi Hung Road, which both are essential roads in Diamond Hill area with congested underground utilities. As Choi Hung Road was one of the frequent flood region in Hong Kong., the excavation and lateral support work has to overcome more than 12m retaining depth with high groundwater table together with the aforementioned challenges to provide safe and cost-effective design of the temporary works.
