Compared to traditional cast-in-place construction, prefabricated buildings involve additional stages such as production and transportation, which contribute to higher overall costs. Effectively managing these stages can significantly reduce the price gap between prefabricated and cast-in-place buildings, thereby promoting wider adoption of prefabrication. This article explores how BIM technology can optimize transportation costs in prefabricated construction and offers practical recommendations to support its advancement.
Several key factors influence the transportation phase of prefabricated buildings: route selection, vehicle choice, component placement, and loading/unloading site selection.
First, route selection can be optimized by gathering real-time traffic data and identifying roads that meet the requirements for transporting components, avoiding congestion, and maintaining a steady speed. This information can be integrated into a BIM collaborative platform to optimize transportation paths efficiently. By incorporating RFID technology, the transportation process can be monitored dynamically, ensuring components arrive on site promptly.
Second, vehicle selection requires detailed information about the vehicle’s location, load capacity, size, and driver credentials. Importing this data into the BIM platform allows all stakeholders to track vehicle status in real time and respond quickly to any emergencies.
Third, component placement should be carefully planned according to construction simulations. Random placement is strictly prohibited, as organized arrangement improves installation efficiency and overall workflow on site.
Finally, selecting loading and unloading sites should be guided by the site optimization plan developed during the design phase. The goal is to minimize inventory time and maximize turnover, making full use of available on-site space to boost construction efficiency and reduce costs.
