| Abstract | This research studied the construction performance (durations, costs, and quality) ofone-storey and two-storey houses built by traditional and precast load-bearing wall systemsand analyzed the effects of the number of floors on the house construction performance.The study was done by (1) a detailed observation of the construction processes of eighthouses, i.e. two one-storey houses & two two-storey houses built by the traditional systemand two one-storey houses & two two-storey houses built by precast technology, and(2) an interview of three senior construction staffs in a housing project. The results wereanalyzed by Descriptive Statistics and Content Analysis. The results showed that: (1) As tothe quality perspective, it was found that the number of defects per area is constant forprecast load bearing wall houses while it is increased for conventional ones, when thenumber of floor is increased; (2) The construction durations of the traditional system housesare increased (130.26%) depending on the number of floors because the upper storey havemore processes than the first storey. On the other hand, construction duration in precasthouses will be less increased (55.00%) when the storey is increased because the second-floorcomponent installation will be faster than the first floor ones and the amount of componentsin the upper storey is also less than the first storey; and (3) The unit cost of precast housesis decreased when the number of floor is increased while that of conventional houses isincreased. The findings can help real estate developers select the building systems appropriateto the houses in their projects. |
