Today, we will discuss the applications of BIM technology in construction. By utilizing BIM technology for virtual construction, managers and supervisors can simulate the assembly of components before actual labor and material installation. This includes the assembly or adjustment of construction procedures for substitute component products.
BIM in Design Change
BIM provides real-time feedback to improve the accuracy of overall cost estimation. For example, it allows extraction of quantities and other data from Revit models to calculate costs efficiently. Regarding cost control, since the BIM system contains all information and materials related to the hypothetical building—including its structure and equipment—the quantities of equipment and materials can be calculated quickly and accurately. This enables timely cost information for the plan and facilitates easy comparison and response to cost changes according to specifications.
Risk Management with BIM
The application of BIM in risk management involves computer-aided construction risk assessment combined with visualization through building information models. This approach employs the concept of source management to conduct risk assessments during the construction planning stage, helping to identify potential risks early on. Using information technology, a risk assessment system has been developed that operates via a network to assist and guide the construction industry through stages such as engineering planning, design, and construction. The system records data outputs and results for each stage, producing relevant reports as needed.
Moreover, to help construction personnel understand the timing and spatial location of hazards on site, risk assessment results are visualized within the building information model. This visualization aids in reviewing the appropriateness of risk countermeasures and allows real-time responses with necessary adjustments.
Project Schedule and Spatial Utilization Planning
In recent years, both the engineering and academic communities have actively promoted the use of Building Information Modeling (BIM), especially by integrating BIM models with project scheduling to create 4D models. These models use 3D visualization to assist with project progress management. However, current 4D models based on BIM’s 3D architecture have not yet fully realized BIM’s potential.
A proposed progress planning model integrates BIM with construction computer simulation. This model uses BIM-calculated quantities of steel formwork and concrete and transfers this data to site-level construction simulation. By analyzing quantities and construction rates, it helps determine the duration of each task on-site, accounting for competition between human and machine resources as well as uncertainties in working time.
The model analyzes overall project completion time, transfers simulation results to the construction schedule at the activity level, and combines these with BIM’s 3D components to produce a 4D visualization. After testing with an actual case, this model was verified for feasibility.
Safety and Hygiene Applications
Construction projects often face delays and uncontrollable costs. Implementing accurate quantity estimates can help prevent these issues. Temporary facilities used only during construction phases are often overlooked in funding, leading to budget diversions and compromised safety. Although there has been an emphasis on allocating budgets for safety based on actual conditions, difficulties in estimating quantities have hindered effective implementation.
Without proper safety funding, temporary projects cannot guarantee safety, increasing the risk of serious occupational accidents that may lead to work stoppages and negatively impact project progress.
BIM technology has been introduced to improve safety planning and management within project engineering. Complex projects require many temporary facilities, such as construction frames, which need to be modeled and managed in phases. Additionally, safety and hygiene protection measures are planned visually, allowing construction teams to clearly identify where protective nets and safety passages must be installed to ensure worker safety.
That concludes our overview of the applications of BIM technology in construction. I hope this article has been helpful to everyone!
