To improve the accuracy of error correction for precast concrete component hoisting， a millimeter level dynamic correction algorithm for precast concrete component hoisting error based on iterative closest point （ICP） and building information model （BIM） was studied. A BIM of precast concrete components is constructed to analyze and quantify hoisting errors. Based on the ICP algorithm， the component point set is subjected to rotation and translation transformations. The error compensation is calculated by minimizing the average distance between the actual and theoretical point sets， enabling secondary feedback-based dynamic correction of hoisting errors.The experimental results show that the corrected component lifting error of this method is ±2 mm， and the probability of the lifting error distribution between 0~0.10 mm is 60%，indicating a high correction accuracy.
