16 major applications of BIM technology in construction management

1. Virtual construction

BIM-based virtual construction, the construction itself does not consume construction resources, but can see and understand the process and results of construction according to the visualization effect, which can greatly reduce the cost of rework and management costs, reduce risks, and enhance the manager's ability to control the construction process.

2. Modeling of building components

First of all, according to the architectural drawings, the whole construction project is decomposed into various components, and through the three-dimensional component model, their size, volume and weight are directly measured, and the type and model of materials used are recorded, and the construction equipment and tools are selected for the main components, and the construction method is determined. Through the modeling of building components, it can help the builder to study how to construct and install the components on site in advance.

3. Construction site modeling

The virtual five-dimensional model of the construction site can intuitively and conveniently assist managers to analyze the constraints of the site, find out potential problems, and formulate feasible construction methods. It is conducive to improving efficiency, reducing the possibility of loopholes in the traditional construction site layout method, early detection of problems in construction drawing design and construction scheme, and improving the productivity and safety of construction site.

4. Construction machinery modeling

The construction method is usually determined by the use of engineering products and construction machinery, and the overall planning of the site, the site space, the production capacity of the machinery, and the method of mechanical installation and dismantling determine the selection of the construction machinery.

5. Modeling of temporary facilities

Temporary facilities are for the construction of the project, its arrangement will affect the safety, quality and production efficiency of the construction of the project, the five-dimensional real model virtual temporary facilities are very useful to the construction unit, can realize the layout and use of the temporary facilities, can also help the construction unit accurately estimate the resources required in advance, and evaluate the safety of the temporary facilities, whether it is convenient for construction, and find possible design errors.

6. Visualization of construction methods

The visualization of construction method makes all project participants can clearly know all the construction content and their job responsibilities before construction, can promote effective communication in the construction process, it is a simple, economical, and safe method to evaluate construction methods, find problems, and evaluate construction risks at present.

Virtual construction with BIM requires the following information to be determined in advance: a 5D model of the design and the on-site construction environment; According to the components of the selection of construction machinery and the operation mode of machinery; determine the manner and sequence of construction; Determine the required temporary facilities and installation locations.

7. Construction method verification process

BIM technology simulates the entire construction process, allowing project managers, engineers and construction personnel to understand every step of the construction process. If problems are found, engineers and construction personnel can propose new methods and simulate new methods to verify whether they are feasible, and most of the construction risks and problems can be identified and effectively solved before the construction of the project.

8. Effective communication tools among project participants

The visualization of the construction process makes BIM a communication platform that facilitates the communication of all parties involved in the construction. Through this visual simulation, the time for on-site staff to be familiar with the construction content and methods of the project is shortened, the time and cost for on-site personnel to make mistakes in the early stage of project construction are reduced, and the speed and depth of training for project participants can be accelerated and deepened.

9. Workspace visualization

The visualization of BIM is dynamic, and the construction space will constantly change as the project progresses, which will affect the work efficiency and construction safety of workers. By visually simulating the construction status of the workers, it is possible to visually see the position of the construction face and construction machinery, and evaluate the availability and safety of these workspaces during the construction process.

10. Material cost control

The data exported by applying the BIM model can be directly applied to the project budget, which provides a favorable basis for cost control and construction final accounts. In the past, the final accounts of construction were calculated with drawings, but with the model, the data is completely automatically generated, and the accuracy of the final accounts and budgets has been improved.

11. Construction organization control

With the help of BIM's simulation of construction organization, project managers can intuitively understand the time nodes and key processes of the interval construction process, and clearly grasp the difficulties and key points in the construction process, and can further optimize and improve the construction plan to improve the construction efficiency and safety of the construction plan.

12. Visual drawing output

The construction pictures output by the visualization model can be distributed to the construction personnel as visual work operation instructions or technical disclosure, which can be used to guide the construction of the site, so as to facilitate the construction management personnel on the site to take the drawings for construction guidance and on-site management.

13. Based on BIM construction management objectives

With virtual construction based on BIM technology, construction units can achieve the following goals: create, analyze, and optimize construction schedules; Analyze the feasibility of the construction methods to be used for specific projects; By simulating the visual construction process, the construction problems can be detected in advance and the hidden dangers of construction can be eliminated; Visual communication tools to enable project participants to better understand the scope of the project, and provide visual work instructions or technical disclosures; Design changes can be managed more effectively; New concepts and methods of trial and error, error correction.

14. Construction project quality management

Since the drawings designed with BIM are digital, computers can play an advantage in retrieval, discrimination, data collation, etc. Whether it is the supervising engineer or the contractor's project management personnel, they do not have to take the thick drawings and check them repeatedly, but only need to quickly and accurately obtain the characteristic information of the building components through some simple functions, such as the layout of the steel bar, the location of the reserved holes in the equipment, the size of the components, etc., and issue instructions in time on the spot.

The BIM model and construction plan are used to integrate the data of the virtual environment, and the constructivity of the construction project can be simulated and experimented, and the quality problems can be found in advance.

15. Construction project progress management

BIM can visually display the project schedule by month, week and day. On the one hand, it is convenient for project management personnel to compare different construction plans and select construction plans that meet the schedule requirements; On the other hand, it is also convenient for the project management personnel to find the deviation between the project plan progress and the actual progress, and make adjustments in time.

16. Construction project investment (cost) management

On the BIM platform, the elements of the design drawing are no longer lines, but components with attributes. There is no longer a need for the budgeter to tell the computer what it is drawing, and the "3D takeoff" is automated. Secondly, BIM makes investment (cost) control easier to implement.
