Abstract
Over the last few decades, precast concrete elements have become a popular component for construction projects. Since success of the precast concrete based construction comes from the dimensional conformability of individual precast concrete elements to their design specifications, checking the dimensional qualities of individual precast concrete element is very important. This paper presents a laser scanning and Building Information Modeling (BIM) based quality assessment technique that automatically measures the dimensional properties of atypical precast concrete elements. In this study, a new algorithm is developed to match the scanned data obtained from a laser scanner with the as-designed model of precast concrete elements. Validation experiments are conducted on actual atypical precast concrete elements to identify the effectiveness of the proposed technique. The test results show that the dimensional errors between the scanned points and the asdesigned model have a 2.6 mm, which is satisfactory accuracy for successful dimensional quality assessment of precast concrete elements.
