Defects at Post-Handover on Precast Concrete Residential Housing Case study from 3-storey precast concrete housing

Abstract

A significant portion of the labor force in Thailand is employed in the construction sector, depending on productivity. Precast technology can accelerate time-sensitive projects. In order to hasten the completion of time-sensitive projects, precast construction techniques resulted in an increase in the work's overall quality, as well as time and money savings, as well as reduced costs for both construction and ongoing maintenance. A recent study found that the residential sector had a significantly higher rate of defects and rework than other sectors. To optimize project management, planners and engineers need to know about defects and the
associated cost. This study follows Pareto’s principle. There are statistically significant relationships among defects. In this paper, a total of 6,360 post-handover defects were derived from real 3-storey precast concrete housing constructions in Bangkok and its vicinity. More attentions related to bedroom1 defects should be considered in the post-handover process.
