A study of problems in the construction of building engineering systems after the delivery of low-rise condominiums

The real estate business focuses on improving the quality of work during the construction period. However, problems from design and construction after the project has been delivered are likely to arise and it is important to gather information for qualitative adjustments during the construction phase. The purpose of this research was to study and analyze the frequency and impact of problems from building engineering systems after the delivery of low-rise condominiums in Bangkok and its vicinities. This research was a survey research and data were collected by questionnaires with a sample of 400 residents of low-rise condominiums. Most of the respondents lived in low-rise condominiums in Bangkok and its vicinities with a selling price of 70,000- 129,999 baht per square meter. The data were analyzed using descriptive and inferential statistics. The results of the study revealed that the problems with the highest Severity Index (SI) in the top three were 1) problems with unstable internet signal 2) problems with insufficient electrical outlets in the rooms and 3) problems with breaker cabinets installed in inappropriate position. In addition, the hypothesis testing revealed that the opinions of residents in condominiums with different selling prices had different frequency and impact of problems. Finally, this research recommends the prevention of problems as a guideline for future construction project management.
