Go over the mountain and overcome the challenges to power the city

Abstract

ABSTRACT To cope with future electricity demand and upgrade power system stability against extreme weather, CLP Power Hong Kong Limited (CLP Power) has developed a new 400kV overhead line circuit. The project involved building a new gantry situated on a natural steep slope, which natural terrain hazards including open hillslope failure, rockfall needed to be addressed. This technical note discussed the technical considerations and challenges to cater for the geological settings, methodologies applied in the geological assessment from desktop studies, site reconnaissance, natural terrain hazard assessment, mitigation measures, foundation design, and the use of Building Information Model (BIM) to enhance project planning and development.
