Abstract

Abstract

Prefabricated steel structures are widely used in modern construction for their efficiency and environmental benefits. However， during the assembly process， factors such as manufacturing errors， deformations during transportation， and on-site assembly inaccuracies can reduce assembly precision， affecting the structure’s stability and safety. Traditional construction control methods rely on manual measurements and empirical judgments， which are insufficient for achieving high-precision and high-efficiency construction. To address these challenges， first， high-precision 3D scanning technology was employed to accurately measure prefabricated steel components， capturing their shape and deviation data for comparison and analysis against the design model. Next， by integrating Building Information Modeling （BIM）， a digital construction control system was established to assess assembly errors and improve installation accuracy through optimization and adjustment strategies. Additionally， an error compensation algorithm was introduced to adjust component positioning and correct deviations based on working conditions， ensuring alignment during assembly. Finally， a digital monitoring platform enabl real-time tracking of the construction process， optimization of control strategies， and enhancement of construction quality and efficiency. Experimental studies and engineering applications demonstrate that this technology improves the assembly accuracy of prefabricated steel structures， mitigates the impact of error accumulation on overall structural performance， enhances construction efficiency， and reduces costs.
