The traditional cost management model used during the construction phase of highway engineering projects faces several challenges. These include a lack of process control, insufficient refinement in cost management, slow data updates, poor timeliness in sharing engineering data, and inadequate coordination and collaboration. Furthermore, in construction models such as BOT and EPC, project progress often takes precedence over other factors. Investment parties, driven by their interests, typically shorten the construction period. As a result, construction costs increase to ensure quality and safety, leading to an uncontrollable situation regarding overall expenses.
Integrating BIM technology into the cost management and control of highway projects during construction has led to the establishment of a 5D-BIM cost management system. This system combines project entity information, construction progress timelines, and various process data to address the shortcomings of traditional cost management approaches and enable more refined control.
By simulating construction processes, the 5D-BIM system identifies planning flaws and potential issues that may arise during construction, helping to avoid costly rework and saving on construction expenses. It allows project managers to quickly retrieve essential data and details about specific structures and construction sections, enabling precise resource allocation for personnel, materials, and machinery. This reduces unnecessary waste and effectively controls project costs.
Regarding project completion and settlement, the 5D-BIM cost management system contains comprehensive engineering data for every stage of the project. This significantly shortens the time required to review settlement data, prevents disputes caused by uncertainties, improves settlement efficiency, and shortens the settlement cycle, all of which help save costs.
Additionally, the system dynamically tracks and manages income and expenses throughout the construction progress. This facilitates ongoing inspections and accounting, ensuring better financial control during the entire process.
