Today, let’s discuss the advantages of BIM application in the construction industry and its significance. BIM enables the visualization of three-dimensional images and direct data display. Different operators can store and access data, generate reports, and compare information during the construction process. Even if you are not an industry expert, with some practice, you can interpret and understand these charts. This capability facilitates communication between experts and clients, district councils, or other stakeholders, reducing misunderstandings, enhancing transparency, and strengthening collaboration.
Because BIM data can be stored in the cloud, professionals across various fields have access to real-time information. This not only saves time but also minimizes errors, disputes, claims, delays, and overspending. Field personnel can view data on-site through augmented reality (AR) and virtual reality (VR) applications using tablet devices, ensuring that the design perfectly matches the actual objects. Improved efficiency helps alleviate manpower shortages and boosts productivity. BIM is generally categorized into two types: “design” and “completion.” For new large-scale engineering projects, teams create design BIM models that support future facility management.
Regarding existing buildings, land surveyors utilize laser scanning and photogrammetry techniques to capture current conditions and develop completion BIM models for ongoing facility management. This makes BIM valuable for environmental and historical preservation. For example, when planting energy-saving and cooling vegetation on building exteriors, BIM can record data related to watering, fertilization, costs, and suppliers, simplifying management. Taking historic structures like Queen’s Pier or Lei Shengchun as examples, only laser scanning is needed before demolition or revitalization to create a completion BIM model. Later, design BIM models can be developed for reconstruction projects.
Implementing BIM requires a fundamental shift in work culture and extensive preliminary preparation. Detailed planning must begin early in the project, as BIM integrates throughout the entire construction lifecycle — from design and bidding to building maintenance. Studies abroad indicate that without BIM, upfront engineering costs make up about 5% of total project expenses. However, when using BIM, these costs can increase significantly, reaching up to 20%.
After adopting BIM, the entire design process must be completed in advance. Architects and engineers are required to submit their design models on time so they can be integrated into an overall model. This approach helps identify inconsistencies early and enables timely corrections, reducing the time and labor needed for revisions during construction. BIM’s ability to present three-dimensional designs assists in evaluating the project’s surrounding environment and assessing feasibility. The project team can analyze different parameters and design options based on computer simulations. For quantity surveyors, BIM models include detailed information about quantities and technical specifications—such as doors, windows, walls, and floors—making measurement and cost estimation easier.
Moreover, BIM’s parametric modeling function allows real-time visualization of design changes and automatic adjustment of related material quantities. Digitizing material measurements reduces repetitive manual work. Once a digital database is established, quantity surveyors can provide clients with faster engineering estimates and five-dimensional BIM services. BIM is especially effective for coordinating complex piping and equipment installations, as well as managing large-scale construction projects involving asset or facility management data. In addition, BIM supports innovative geometric designs for landmark buildings.
That concludes our discussion on the advantages and significance of BIM in the construction industry. I hope this article has been helpful to everyone!
