Application of BIM and 3D laser scanning for quantity surveying and quality management in construction projects

Abstract

Numerous construction companies consider the work of addressing deficiencies, defects, and controlling volume amid construction projects is time-consuming, high-price, and to be one of the most challenging issues confronted by project management. The manual quality assurance programs currently used have certain restrictions, counting the lack of consistency in programs and human errors. Hence, one vital requirement is a need for integrated digital models that utilize new technologies and methods. As a result, BIM and 3D Laser Scanning have risen as helpful technology in transferring data to the digital module and processing create spatial objects. By adopting the integration of the BIM model and 3D Laser Scanning advantageous, the accuracy and efficiency of the quantity management process can be improved. This paper presents six case studies where (1) observes the current status of conventional methods in QA, QC; (2) demonstrates overview tasks for the integrated application; (3) determines the benefits and shortcomings of the integration; (4) identifies the workflow; (5) applies and evaluates the proposed workflow for real projects; and (6) evaluates the orientation of research.
