ELS Clash Analysis Experience Sharing

by Kenny Zeng (Design Manager, Leighton Asia)

Excavation and Lateral Support (ELS) methods are extensively employed in the construction sector for the excavation of existing ground, enabling the construction of pile caps, basements, and a variety of underground structures. This substantial type of temporary work requires detailed coordination between numerous stakeholders including existing structures, proposed structures, planning, and construction methodology. The intersection of the ELS with other structures frequently results in clashes leading to potential delays, increased costs, and even safety risks, which are mitigable, or even avoidable with the correct application of Clash Analysis. Our online seminar showcases the lesson learn, and how the use of Clash Analysis can significantly reduce these implications, fostering a more efficient and safer construction environment.
