CS was selected in 2006 as part of a design and build a team to propose the use of a steel lift shaft for HDB with a 20:20 target- 20% shorter construction time at 20% cost savings. The pilot scheme involved 4 numbers of ten-story blocks at Marsiling and 2 numbers of low-rise 4-story blocks at Jurong West. The project was completed with a single-day installation of the lift shafts. HDB has since raised its target to 30:30 and we are involved in 9 other HDB projects since, with more than 100 blocks. The total project value is more than $400 million. Our involvements are either direct appointments from HDB or part of the design and build a team.  So far, we have a 100% success track record for the design and build tenders we have participated More significantly, we are involved in more pilot projects such as shaftless lifts, home lifts, rental blocks flat conversion, type C mid-landing, etc, a recognition of our ability to contribute actively and using innovative ideas to come out with buildable, economical and time-saving solutions.
