What benefits does BIM technology bring to owners, design and construction?

BIM technology plays an irreplaceable role in the construction industry, and the emergence of BIM technology will trigger the second digital revolution in the field of engineering and construction.Bentley ProjectWise BIM not only brings the progress and upgrading of the existing technology, but also influences the change of the production organization mode and the management mode, and promotes the change of the way of thinking of people.

With the arrival of the information age, BIM technology has emerged.Bentley BIM By fully integrating and utilizing the information involved in the whole life cycle of a construction project through the application of BIM models, it can not only shorten the time required for a construction project and save the cost of resources, but also help all project participants to improve the efficiency of decision-making and the quality of design.

In recent years, BIM technology has been favored by the public. Utilizing BIM technology can support and improve many of the business processes of building design and construction, and solve more complex problems in the construction process, with irreplaceable benefits for owners, designers and builders.

Benefits that the pre-construction phase can bring to our owners

Improved collaboration using integrated project delivery.BIM Viewer When an owner procures a project using Integrated Project Delivery (IPD), the project team can use BIM early in the design process to improve their understanding of the project's requirements and avoid written communication and associated delays.

2. Concept, Feasibility, and Design Presentation When an owner asks a designer to design, he or she needs to determine the specified size of the building, the level of quality, the expected specifications required, and whether it can be built within the predetermined budget and timeframe. The designer should assess whether the building will meet the owner's financial needs. If they can give a relatively positive answer, the owners can expect the goals to be met. If a lot of time and effort is spent only to realize that the design is way over budget, a lot of resources have been wasted. Therefore, a rough (or macro) model of the building built into or connected to the cost database brought about by BIM collaborative management technology can be valuable and helpful to owners.

Improved building performance and quality

Developing a schematic model before creating a detailed building model, it allows for a closer evaluation of the proposed program to determine if it meets the functional and sustainable needs of the building. Using BIM technology as an analysis and modeling tool to evaluate initial design options can improve the overall quality of a building.

Benefits of BIM technology for design studies

1. the BIM software automatically makes low-order corrections when the design changes. objects designed by the BIM software are controlled using parametric rules. The model does not produce errors in geometry, alignment, and spatial coordination, which reduces the need for users to manage design changes.

2, earlier and more accurate design visualization BIM technology software generated by the 3D model is designed directly by the software, rather than generated by multiple 2D views, so at any stage of the process can be visualized performance, the view can be consistent with the actual size.

BIM technology can identify design issues early and provide opportunities for continuous design improvement, rather than waiting until the design is nearly complete and major design decisions are made, making it more cost-effective to perform value engineering analysis.

4. Produce accurate and consistent 2D drawings at any stage of the design. Accurate and consistent drawings can be extracted from any specific view of an object or project, which can save a great deal of time in all areas of specialization and reduce the errors associated with producing drawings at the time of design. When the design needs to be changed, enter the design changes will immediately generate identical drawings.

5. Capture cost accounting estimates at the design development stage

At any stage of design, BIM technology can be used to extract estimates into the correct quantity and space inventory for cost estimation. In the early stages of design, cost estimates are based on formulas that go into a large number of items, such as the number of parking spaces, the square footage of each office space, or the cost per unit of square footage. As the design progresses, more detailed quantities become available, allowing for more accurate and detailed cost estimates.BIM technology allows all parties to understand the costs associated with the design as it progresses to the level of detail required for construction bidding. In the final stages of design, final costs can be estimated more accurately based on the quantities of all items included in the model. As a result, using BIM technology is more likely to produce smarter design decisions than paper-based systems. When using Building Information Modeling to estimate costs, it is of course expected that the contractor responsible for the building structure and possibly the main contractor will be part of the project team, and their knowledge will be necessary for accurate cost budgeting and architectural insight during the design process.

Construction and Manufacturing Benefits.

Identify design errors and omissions prior to construction because the virtual 3D building model is the root of all 2D and 3D graphics, so you can avoid 2D graphics inconsistencies that can lead to design errors. In addition, because models from all areas of expertise can be compared with each other, the multi-system interface is easy to check systems (hard space clashes) and visualize (other types of errors), clashes and construction problems can be detected prior to testing on site, which improves coordination between the designers and contractors involved, and can dramatically reduce errors, speed up the construction process, reduce costs, and lessen the likelihood of legal disputes for the entire project team Provides a smoother process.

2. Better implementation of lean construction techniques requires careful coordination between the general contractor and the various subcontractors to ensure that the work can be carried out when the appropriate resources are available on site. This reduces wasted energy, reduces the need for on-site material inventories, and ensures the timely arrival of personnel, equipment, and nuclear materials, effectively reducing the cost of time. In addition, the model can also be tracked through wireless devices materials, installation progress and automatic site location.

3, design and construction companies to synchronize procurement A more complete building information model will provide the system design within all (or most, depending on the level of 3D modeling) materials and objects for the exact number of these issues number, specifications, and attributes can be used as a basis for procurement to product service providers and subcontractors. Currently many of our company product manufacturing object definitions have not yet been developed, leaving this campaign feature completely unimplemented, but when this modeling is available (steel industry structures, precast concrete constructions, some Chinese mechatronic components, and some windows and doors), analysis of the results can be very helpful.

4. Rapid response to design changes, where proposed design changes are entered into the model for automatic updating of changes to other objects involved, some updates are automatically updated according to established parameterization rules, other cross-system updates are checked and corrected visually or through clash detection, and the results of the changes and all subsequent attempts are accurately reflected in the model. In addition, design changes can be resolved more quickly in a BIM system because they can be shared, visualized, predicted, and resolved without written communication. This method of updating is highly error-prone in image-based systems.

5. Simultaneous design and construction planning BIM4D technology is used for construction planning, where 3D objects need to be connected in the design so that the construction process can be simulated, showing at all times how the building and the base will look. This graphical simulation provides insight into how the building is constructed on a day-to-day basis, revealing potential problems and possible opportunities for improvement (bases, personnel and equipment, spatial conflicts, safety issues, etc.). , and the written solicitation documents could not provide this analysis. Additionally, by including temporary construction objects such as protective walls, scaffolding, cranes, and other major equipment in the model, the added value associated with time-constrained activities can be increased and reflected in the anticipated construction schedule.

Use the design model as the basis for prefabricated units. If the design model is transferred to a BIM tool and detailed to the point of fabrication (fabrication model), it will accurately represent the building object, and for ease of fabrication and construction, it has been used successfully for prefabricated components, windows, and glazing fabrication.BIM enables global suppliers to add detail to the model, develop details as needed, and maintain links to the design intent, making off-site production more easier and reduces costs and construction time. The accuracy features of Building Information Modeling allow for the need for site changes (rework) and the ability to react to other projects after site completion to get an accurate sized picture of what is going on.BIM also allows for smaller installation crews, faster installation times, and less on-site storage.
