Architectural Quality Factors Affecting the Cost of Condominium Construction, A Case Study of the Collect Ratchada 32 Project

The purpose of this study was to (1) evaluate factors affecting architectural quality that affect the cost of condominium construction on a case of the Collect Ratchada 32 project, and (2) to find solutions for preventing architectural quality. The research was carried out by gathering information from a specific sample of management group (10 samples), with 5 samples of in-depth interviews (2 executive officers, 1 site manager, 1 engineer, and 1 construction architect) using quantitative and qualitative research. Descriptive statistics, frequency distribution method, percentage determination, mean, standard deviation (SD), inferential statistics, and multiple linear regression analysis were used to analyze the collected data. (1) Architectural factors (floor work, wall work, ceiling work, door-window work, sanitary work, miscellaneous work) were found to be moderate in terms of defect. All architectural quality factors (construction contract duration, construction cost, construction tools/mechanical equipment, project management, pattern activity, and project environment) were moderate. (2) The most expensive cost for repairing the defects came from the wall and floor defect repairs, which spent more than 50% of the total fixing cost.
