BIM technology is primarily utilized during the decision-making phase to conduct feasibility studies for construction projects, focusing on both technical and economic aspects. It enhances the accuracy and reliability of study results. During this feasibility study stage, the construction team must determine whether the project plan is technically and economically viable, while also meeting requirements related to type, quality, and function. However, obtaining highly reliable conclusions can be time-consuming, costly, and labor-intensive. BIM offers a comprehensive schematic model that allows construction teams to analyze and simulate project plans, effectively reducing costs, shortening construction timelines, and improving overall project quality. This article explores the application of BIM technology in site analysis and scheme demonstration during the decision-making stage, particularly in managing change control.
1. Site Analysis Using BIM Technology
Site analysis involves examining key factors that influence building positioning, determining spatial orientation and appearance, and establishing the relationship between buildings and their surrounding landscape. In the planning and decision-making phase, factors such as topography, vegetation, and climate conditions significantly impact design decisions. Site analysis typically evaluates multiple elements including landscape planning, environmental conditions, construction infrastructure, and post-construction traffic flow.
Traditional site analysis methods often suffer from insufficient quantitative data, subjective biases, and limited capacity to process large datasets. By integrating BIM with Geographic Information Systems (GIS), spatial data for the site and proposed structures can be accurately modeled. Leveraging the advanced capabilities of BIM and GIS software, rapid and reliable analysis results can be generated. This supports project teams in assessing site usage conditions and characteristics, facilitating critical decisions such as optimal site planning, traffic flow management, and building layout for new developments.
2. BIM-Based Scheme Demonstration
During the scheme demonstration phase, project investors can utilize BIM to assess various aspects of the design, including layout, sightlines, lighting, safety, ergonomics, acoustics, texture, color, and compliance with relevant standards. BIM enables detailed analysis of specific building components, quickly identifying potential issues that may arise during design and construction.
In the decision-making stage, BIM also provides cost-effective and convenient options for investors to compare different solutions. Through data-driven simulations and comparisons, the strengths and weaknesses of various proposals become clear, helping investors make informed decisions regarding construction costs and timelines.
For designers, BIM facilitates an interactive evaluation of the designed spaces, allowing them to gather valuable feedback from end users and construction teams. Real-time design adjustments are often made based on this feedback. The BIM platform presents key project concerns intuitively, enabling all stakeholders to reach consensus more rapidly, which significantly reduces decision-making time compared to traditional methods.
Increasingly, scholars and institutions recognize pre-planning as a vital phase in the full lifecycle management of construction projects. The integration of building information modeling into this stage is gaining attention. By applying BIM technology, construction teams and stakeholders can use parametric modeling to digitally represent all project information and its external impacts.
This real-time, accurate data allows for comprehensive evaluation and optimization of the proposed project, selecting the best planning scheme to improve decision quality. It also substantially reduces engineering changes during construction and provides more precise initial cost estimates. Additionally, BIM supports future building operation, maintenance, and facility management, contributing to sustainable cost savings over the building’s lifecycle.
