Design constraints
1. A fast track project which construction time is limited.
2. Built on reclaimed land and specified membrane system to be employed in
basement.
Solutions
To save construction time, Contractors since Phase II had submitted our Everdure Caltite System as alternative waterproofing system to replace the membrane system as stated in the Specification. As it was totally a new approach and the use of admixture was not common at that time, therefore Consultants granted the greenlight only based on a commitment that Contractors had to establish a tight monitoring system during the whole construction process to ensure the best of the performance was achieved.
