Lift Upgrading Programme

Lift Upgrading Programme (LUP) (Chinese: 电梯翻新计划, Malay: Program Peningkatan Lif[1]) is a Singapore Housing and Development Board (HDB) project which upgrades and improves the facilities of the lifts at HDB flats.

Singapore is an island country with land limited to 700 square kilometers and a population of 4 million; this population density means it is inevitable that most of its residents must live in high-rise apartments and work in high-rise commercial and industrial buildings.

TMS uses SCADA technology to monitor the status of the lifts in real-time from a centralized master station for events such as breakdown and trapped passengers.

The lift maintenance companies are automatically notified of any problem and in most cases, repairs are carried out even before a complaint is received.

The introduction of TMS has resulted in better lift performance as historical data allowed the Town Councils, who are maintaining the HDB estates, to pinpoint problem areas and improve the method of maintenance.
