Today, we will discuss the benefits of BIM technology and its applications at each stage of a project. BIM, or Building Information Modeling, integrates various technologies to transform traditional construction practices. The most significant change it brings is the need for intensive collaboration and comprehensive coordination among all stakeholders in the construction industry before analysis and execution. This collaborative approach is also the biggest challenge in its widespread adoption.
Traditionally, construction relied on 2D drawings and historical data, which often resulted in a lack of coordinated data exchange and wasted resources due to repetitive tasks. In the United States alone, this inefficiency has caused social losses amounting to nearly $15.8 billion annually. This is one of the key reasons why BIM policies have gained importance.
With the rapid development of software applications and web computing services, equipment manufacturers are investing heavily in system services that provide detailed information on construction facilities and equipment. Contractors and designers depend on this accurate information to manage projects intelligently, perform analyses, and make informed decisions.
The standards and workflows defined by the National BIM Standard (NBIMS) have been gradually integrated into market-leading software products. Architect Lott & Barber from the United States highlighted that compared to traditional design methods, BIM can save:
- 53% of working time during schematic design;
- About 50% of time in design development;
- Approximately 20% during the production of construction documents;
- Up to 91% in inspection and coordination;
- Overall, around 38% time savings compared to traditional workflows.
Research also points out two important observations: first, individuals with strong abstract reasoning skills may find CAD more efficient than Revit. Second, when it comes to data comparison, Revit tends to be more efficient than CAD because it automates component counting, eliminating the need for manual calibration.
Building Information Modeling (BIM) offers the fastest and most noticeable advantages by making building construction more accurate, faster, and cost-effective. Through BIM models, potential problems can be identified early, ensuring smoother coordination across different project phases. Construction drawings derived from BIM significantly reduce on-site errors.
The benefits of BIM extend beyond design and construction. Its true value often lies in the operation and maintenance phase after project completion, where it continues to generate significant advantages. Below, we outline BIM’s specific applications at each project stage:
Design Phase
- 3D visualization of models, facilitating design, construction, and operation planning;
- Visualization of the building construction process to improve communication, discussion, and decision-making;
- Comprehensive coordination to minimize unreasonable or problematic plan changes;
- Resolving incompatibilities between different work elements;
- 3D image simulation and 4D construction scheduling simulation;
- BIM 5D cost control simulation;
- Environmental simulations, including sunlight and thermal energy;
- Disaster evacuation simulations to optimize safety plans;
- Optimizing engineering pipeline design;
- Collision detection to reduce errors, rework, and improve construction accuracy through updated drawings.
Construction Phase
- Providing real-time information on building quality, progress, and costs;
- Visual simulation and management during construction;
- Paperless workflows for processing and manufacturing;
- Using BIM models for construction planning and evaluation;
- Enhancing detail in construction drawings to reduce management issues on site.
Operation and Maintenance Phase
- Providing detailed information on building facilities and equipment;
- Offering relevant data related to spatial, temporal, and financial aspects of the building;
- Maintaining updated records to improve building relocation planning and management.
In conclusion, the benefits of BIM technology and its diverse applications throughout a project’s lifecycle are clear. We hope this article has provided helpful insights into how BIM can revolutionize the construction industry.
