Advances in Constructional Engineering

The hoisting construction of modular building units is a complex engineering task involving multiple processes and links, with extremely high requirements for the control of construction errors. To ensure the precision of hoisting construction and reduce quality problems caused by errors, it is necessary to adopt effective error control methods. This study focuses on exploring the sources of errors and their control strategies in the hoisting process of modular building units, and proposes an error control method based on data monitoring and precise positioning technology. By analyzing the position errors, angle errors, and deviation accumulation phenomena during the hoisting process, and combining advanced sensing technologies and automated control systems, this paper puts forward targeted solutions. Through scientific construction planning and the cooperation of high-precision equipment, construction errors can be significantly reduced, and the engineering quality and safety can be improved, providing a theoretical basis and technical support for the popularization and application of modular buildings.
