Abstract
This study aims to explore the perception of stakeholders on an internal wall quality
assessment during the process of quality inspection prior to delivery of high-rise buildings in
Thailand. In this research, qualitative research is conducted on eight purposive interviewees,
with the collected data analyzed using content analysis. The findings indicate that owners,
consultants, designers, main contractors, and sub-contractors agree that the quality of internal
walls in high-rise buildings are measured by the discretion, knowledge, ability, experience,
expertise, and satisfaction of each inspector. Internal wall quality emphasizes flatness,
alignment and evenness, angle, cracks, and range. The acceptable tolerance of work is not
over 3 millimeters per wall side. The measurement of internal wall quality of each project
will execute differently depending on each project. However, there is a lack of clear
prescriptive standards for this type of work, which could be adopted in every project
nowadays, such as tolerance acceptance, tools, and measurement methods. Therefore, to
make a consistence of quality of work assessment between deliverers and inspectors, a
reliable quality assessment guideline should be developed, presenting the principal criteria,
acceptable tolerances, and measurements process and suitable tools for involved stakeholders.
