Abstract
In the construction field, the terms quality assurance and quality control (QA/QC) have an important purpose, which is to provide the final product with the required quality. Some tools must be applied to ensure and control the quality of construction testing and measuring are important examples of such tools. Sometimes they require accurate measurements depending on the issue at hand. Close-range photogrammetry is one of the most important and accurate measuring techniques that does not require direct contact with an object. Additionally, most of the procedure for close-range photogrammetry can be carried out in the office. The objective of this paper is to present the use of close-range photogrammetry as a useful and accurate measuring tool for QA/QC in the construction field. We have applied close-range photogrammetry to two practical cases in a construction site to demonstrate its application to the issues of quality assurance and quality control.
