Based on the speed of construction of our HDB Blocks around Punggol, it normally takes two months to put up three complete floors.
The piling, foundation, footing, varies from project to project because of different ground conditions. So it is difficult to estimate completion time without drawings and specification.
For Blocks 35 and 37, most of the difficult task had more or less been completed, the remaining task is just to lift up prefab components for installation. To reach roof level, it is just a matter of another 10 months. ( raining season, contingencies not allowed for.
If my estimation is correct, Blocks 35 and 37 should reach roof level by July / August 2012. Another 3 months for painting, clearing of debris, landscape architecture, certification etc, December 2012 should be a more appropriate completion date. Progressively, Blocks 33 and 31 should catch up within probably 3 more months.
Hope I'm not too far out........
Thanks for your analysis!
Hope to get the house by early 2013..
