Number and Frequency of Breakdowns of Sigma Brand Lifts since Lifting of Tender Restriction in 2020

Mr Don Wee asked the Minister for National Development of the 3,218 Sigma brand lifts that have been installed in public housing estates since the lifting of the tender restriction on Sigma Elevator Pte Ltd in 2020 (a) whether HDB has data on the number of Sigma brand lifts that have broken down to date; and (b) whether HDB will consider imposing a tender restriction again if the frequency of reported lift breakdowns is considered high.

The tender restriction on Sigma Elevator Pte Ltd (Sigma) was lifted in October 2020 as the performance of Sigma's lifts had improved and was comparable to other lifts in public housing estates. Since the lifting of the tender restriction, the performance of Sigma’s lifts has continued to be stable and comparable to other lift brands.

In the Housing and Development Board (HDB)’s tenders for supply and installation of new lifts, lift performance is a critical evaluation criterion. Tenderers with a higher lift fault rate will be given a lower score during the evaluation. In addition, tenderers will be disqualified from the tender if the track record and performance of the lifts do not meet the criteria.
