ST-00-03 A thesis submitted in partial fulfillment of the requirements for the degree of Master of Engineering, School of Civil Engineering Thesis (M.Eng.) - Asian Institute of Technology, 2000 In the past decade, the economy of Thailand had been in such a great boom. This remarkable strength in economy resulted in a lot of construction of buildings. After the dreadful economic crisis spread all over Asia, many construction projects in Thailand faced inevitable and likely permanent discontinuation. Thus, many partially finished buildings in Bangkok are a common sight. Some of them have been regularly maintained, however some are left unattended. This ignorance sadly causes deterioration of buildings. The purpose of this study is to identify the problems of partially finished building which are unattended for a long time and suggest recommendations on remedial solutions to the problems. To achieve this aim, 20 partially finished buildings were investigated and three buildings were chosen for intensive investigation. The procedure of investigation is divided into three stages. Firstly, general observation to detect signs of defects. Secondly, non-destructive tests were conducted to assess the existing compressive strength of reinforced concrete structures. Finally, possible causes of defects were identified and recommendations on remedial solutions are given. The results showed that most often found defects in partially finished buildings in Bangkok are honeycomb, spalling, and inadequate concrete cover. The main causes of defects are due to poor formwork, improper concrete mix and placing of concrete. Lack of supervision and inadequate construction practices are also causing substandard concrete structures. Another important defect observed in this study is poor construction joint, especially beam-column joints in high-rise buildings. The integrity of buildings depends on the strength of these joints and hence attention should be directed towards the construction of proper joints in the high-rise building. Lack of understanding in behavior of structures, error in design, and error in construction are found to be a serious cause which leads to damages of structures. Two general strategies for remedial solutions to the problems are proposed, namely surface repair and strengthening method. The selection of each method depends upon the type of defects. Surface repair should be adopted for honeycomb, spalling and poor construction joint. Cracks on structural members like beams or columns must be remedied by strengthening method. Rehabilitation by using ferrocement is recommended to use due to its low cost and effectiveness. The investigation indicated that the partially finished buildings should be carefully inspected by experienced engineers before continuing construction to ensure the safety of the structure.
