CONSTRUCTION COST OF EXTRA ROOM IN HDB APARTMENT

Mr J B Jeyaretnam asked the Minister for National Development what is the breakdown cost (showing all components) per unit to the Housing and Development Board for the construction of the extra room in 3-room, 4-room and 5-room apartments in the upgrading programme for HDB apartments.

Mr Lim Hng Kiang: The cost for the extra room or Space-Adding Item (SAI) does not vary very much with the different flat types. However, from project to project, the cost varies with the number of storeys in the block, the design features, soil and site conditions and other construction constraints. The tender prices for each project depends on the prevailing market conditions.

The SAI cost ranges from $15,600 to $31,150. The average unit cost for the SAI based on recent tender prices is about $21,000, with the average cost breakdown as follows: a. Piling $ 2,930 b. Building works $ 11,780 c. Reinstatement works $ 390 d Services Diversion and other Incidental Costs (e.g. Title survey fee) $ 2,220 e. Construction Contingencies $ 870 f. Manpower Cost $ 2,230 Total Cost $ 20,420 Annex (Cols. 125 - 132) AG's elaboration (Cols. 133 - 136)
