A study of structural and architectural problems after the delivery of low-rise condominiums

Low-rise condominiums often experience damage after the building is delivered. This is partly due to poor quality construction during the construction period. The purpose of this research is to study the frequency of problems and the impact that occurred after the delivery of low-rise condominium projects in the category of structural and architectural works. The survey research and questionnaire data collection were used with a sample of 411 residents of low-rise condominiums. Descriptive and inferential statistics were used to analyze the data at 95% confidence level. Most of the respondents lived in the Bangkok area of ​​181 people, representing 44%. The results showed that the problem with the greatest frequency and impact for the structural segment was the cracked concrete road problem. As for the architecture, the most frequent problems are the paint peeling off, cracking of the ivory pattern, and the problem that has the greatest impact is the broken toilet hose problem. In addition, the hypothesis testing revealed that different factors of average selling price per square meter had different frequency of encountering problems and the effect of problems. Finally, this research proposes guidelines for quality control during the construction period as a supporting information for further construction project management.
