Using BIM models during the installation and construction phases of prefabricated building components offers several advantages. It enables rapid and accurate calculation of component consumption and quickly estimates material costs by matching these with unit prices. By incorporating factors such as labor and machinery, BIM facilitates comprehensive cost estimation and project output calculations. Its construction simulation feature allows for three-dimensional site layout planning, including simulating the lifting positions and working radii of tower cranes and hoisting vehicles, as well as the travel routes of transportation and storage vehicles for components. This provides project managers with valuable decision-making support early in the project. Additionally, the simulation of construction stages enhances management and monitoring of construction progress for prefabricated buildings.
(1) BIM Integration
BIM offers strong integration capabilities. Using BIM software for cost target control during construction prevents hidden costs caused by poor communication between departments. For example, the engineering team can simulate construction progress and component assembly using BIM’s simulation functions. Meanwhile, the cost department can calculate component consumption in real time and monitor dynamic costs at each stage. The materials department can track component usage directly through BIM and ensure timely replenishment. The procurement department can access relevant contracts at any time via BIM’s contract management features. Traditionally, communication delays between departments often impact project progress, but BIM usage across departments significantly reduces such issues. This integration lowers management costs, improves construction quality and productivity, and enables multi-dimensional, visual, and detailed project management.
(2) Faster Installation and Risk Reduction
Prefabricated buildings require skilled engineers to guide installation, as technical problems often lead to engineering and safety accidents, increasing costs. By combining BIM with RFID technology, each component receives a unique identification code upon entering the construction site. Engineers can scan this code to instantly access detailed information such as installation location, required tools, and quantity. This reduces the time spent on verification, minimizes errors and rework, accelerates construction progress, and boosts labor efficiency. BIM’s visual installation simulation further lowers labor costs and resource consumption, improves project quality, and reduces total costs. The high integration of BIM simulation with prefabrication technology effectively optimizes construction schedules, enhances efficiency, and indirectly increases the time value of funds.
