Engineering project management is a complex and challenging endeavor that often encounters unpredictable situations. Consequently, the requirements for engineering management must be flexible and diverse. Building Information Modeling (BIM) technology effectively addresses these evolving management needs. For instance, in rail transit projects, BIM technology should be fully utilized for cost control throughout the construction process. BIM technology offers the following advantages:
(1) It integrates all aspects of the project by incorporating every impact factor throughout the entire project lifecycle into a control model. Construction teams can access accurate and comprehensive construction information in real time, making construction efficiency depend less on the experience of veteran workers and more on the effectiveness of the construction plan.
(2) BIM identifies the total engineering quantities from the architectural design and allocates the necessary funds, materials, and other resources for each stage reasonably according to the construction schedule. It estimates project costs based on current market prices and assigns cost responsibilities according to timelines and departments.
(3) Before plan implementation, BIM allows simulation and optimization of the initial design’s construction plans and schemes. This process tests feasibility and scientific validity, enabling reasonable adjustments and optimizations to ensure the construction phase proceeds smoothly according to plan.
(4) During project execution, BIM performs data analysis at each stage to standardize cost control procedures. It provides unified cost information and enables dynamic, real-time adjustments to resource planning based on construction progress and unforeseen site conditions, supporting effective procurement and construction cost management.
(5) By consolidating the project’s physical information into the BIM system, computational functions can analyze discrepancies between actual and planned construction costs, proposing corrective plans to address these variances.
(6) Engineering changes often complicate evaluation of the original plan. BIM captures differences before and after such changes and analyzes their subsequent impacts. It quickly updates the original model and redesigns schedules and plans, offering timely and effective responses that substantially reduce cost management expenses.
(7) BIM serves as a collaborative platform integrating all project participants. Supervisors use it for project reviews, owners for monitoring progress, and contractors for timely communication with subcontractors and suppliers. This collaborative environment ensures that each participant can fulfill their responsibilities efficiently through the technology.
(8) Visualization is a key feature of BIM technology. Engineering projects are divided into cycles, with the work of each cycle recorded and replayable. This replay function allows project managers to identify shortcomings clearly and make necessary adjustments. Through this visualization capability, BIM helps improve construction efficiency continuously by leveraging accumulated experience.
