การนำวิธีก่อสร้างกึ่งสำเร็จรูปมาใช้กับโครงการบ้านเดี่ยวสำหรับผู้มีรายได้น้อย : กรณีศึกษาโครงการบ้านเอื้ออาทร รังสิตคลอง 3 จังหวัดปทุมธานี / ศุภสิทธิ์ พฤกษโชติ = Application of partial precast construction techniques for low income detached housing project : a case study of Aur Arthon Housing Project located on Rangsit Khlong 3, Pathum Thani Province / Suphasit Preukchot
The government has recently implemented a policy of providing 601,727 Low Cost Housing Units over a 5-years period though the well known “Aur Arthon” Housing Project. To construct houses in such a large quantity at minimum time and cost demands better construction techniques. Thus, The National Housing Authority (NHA) requires that all contractors have a mass production construction method as a prerequisite. Thus, each contractor has their construction techniques but none has ever undergone proper evaluation by the NHA. The purpose of this study was to carry out research and evaluation on the suitability of the construction method used in Aur Arthorn Rangsit Khlong 3, Pathum Thani province. The project consists of 477 two storey detached housing units. Each is exactly the same with serviceable area of 51.5 m2. The construction technique used is classified as Frame or Skeleton Type Structure. Results of this study found that the construction technique employed in this housing project is efficient for the overall construction cost of 4,039 baht per m2 (including VAT.). A saving of approximately 5 – 6 % can be obtained when compared with conventional construction. The break even point of capital investment in the formwork system is 221 units (depreciation excluded). The calculated speed of construction is approximately 103 square meters, 2 units per day per construction team. Each construction team consists of seven laborers and one mobile crane. Through interviews with 88 residents, the quality is found to be acceptable but most residents will modify their houses. As a consequences the construction techniques used for The Aur Arthorm Project Detached Housing Project must in-cooperate future modification criteria in their design process. This study also suggest better construction management which, can be achieved by setting up a Precast Institute to provide construction knowledge and expertise in prefabrication construction for architects and engineers.
