Research on Dynamic Control of Construction Schedule in Civil Engineering based on BIM Technology

Abstract

Schedule overruns have been a problem for a long time in civil engineering projects, and the traditional, document-based management mode is no longer suitable for the uncertainties of modern construction sites. Building Information Modelling (BIM) provides a good path forward for moving schedule management from post-event reporting to continuous, model-driven control. Research has been conducted on how to incorporate BIM into all links of construction schedule management and build a closed-loop dynamic control system. Based on the above review of related studies, a three-tier structure has been proposed: a data layer, a model layer and an application layer; the 4D BIM model will serve as the information hub connecting the baseline schedule, field progress data and corrective decision-making. The first two enabling technologies are 4D construction simulation and multi-source progress data collection; the third is BIM-integrated earned value analysis and deviation-driven schedule re-optimisation. Then, the above framework will be applied to a high-rise office building project. According to the case study, after introducing BIM-based dynamic control, the schedule performance index increased from 0.82 in the third month to 1.00 at the end of the project; the frequency of progress coordination meetings dropped by about 40%, and the project was completed on schedule despite serious initial delays. Based on the above analysis, BIM can be employed to establish a closed-loop schedule control system; however, problems such as data standardisation, model granularity and organisational preparedness still need to be solved.
