When the owner uses the integrated project delivery method (IPD) for project procurement, the project team can use Bim in the early design stage to improve their understanding of project requirements and avoid written communication and related delays.
Synchronous design and construction planning use bim4d technology for construction planning.
In recent years, BIM Technology has been favored by the public.
If you spend a lot of time and energy only to find that the design is far beyond the budget, you will waste a lot of resources.
It is necessary to connect the construction planning to 3D objects in the design.

In addition, the model can also track the material and installation progress through wireless equipment, And automatic positioning of the construction site.
At the initial stage of design, the cost estimation is based on the formula for inputting the important quantity of the project, such as the number of parking spaces, the area of each type of office area, or the cost per unit area.
With the advent of the information age, BIM Technology came into being.
Rapid response to design changes input the proposed design changes into the model, the changes of other objects involved will be automatically updated, some updates will be automatically changed according to the established parameterization rules, and other cross system updates will also be checked and corrected visually or through conflict detection, The results of changes and all subsequent attempts will be accurately reflected in the model.

The designer should evaluate whether the building can meet the financial needs of the owner.
The specific views of any object or project can be extracted to produce accurate and consistent drawings, which can reduce a lot of time for all professional fields and reduce the number of errors caused by production drawings in design.
In the final stage of design, based on the number of all items included in the model, the final cost can be estimated more accurately.
Early cooperation in various professional fields BIM Technology can detect design problems earlier and provide opportunities for continuous improvement of design, which is more cost-effective than waiting until the design is nearly completed and major design decisions are made before value engineering analysis.
Benefits to the owner in the pre construction stage 1.
Their knowledge is necessary for accurate cost budget and constructive insight in the design process.
When using BIM to estimate the cost, we certainly hope that the general contractor and the possible key contractors responsible for the building structure will become part of the project team.
Benefits in construction, processing and manufacturing 1.
Better implement lean construction technology Lean construction technology requires careful coordination between the general contractor and all subcontractors to ensure that the work can be carried out when appropriate resources are obtained on site, which can reduce the waste of energy, reduce the demand for on-site material inventory, ensure the timely delivery of insurance, equipment and nuclear materials, and effectively reduce the time cost.
When the design is changed, low-order correction is automatically carried out.
Increase the performance and quality of the building.
Moreover, by including temporary building parts such as protective walls, scaffolds, cranes and other major equipment in the model, the added value connected to construction period activities can also be increased and reflected in the desired construction plan..

Use the integrated project delivery method to improve cooperation.
Therefore, at any stage of the process, visual performance can be carried out, and the view can be consistent with the actual size.
Such graphical simulation provides in-depth insight into how buildings are built every day, exposing potential problems and possible improvement opportunities (bases, personnel and equipment, space conflicts, security problems, etc.), and written bidding documents cannot provide this kind of analysis.
Therefore, the construction process can be simulated and the appearance of buildings and bases can be displayed at any time point.
Conflicts and construction problems will be found before on-site inspection, which will strengthen the coordination between participating designers and contractors and greatly reduce missing errors, Speed up the construction process, reduce costs, reduce the possibility of legal disputes, and provide a smoother process for the whole project team.
These quantities, specifications and attributes can be used as the basis for purchasing from product suppliers and subcontractors.
In addition, because the models of all professional fields can be compared together, the multi-system interface is easy to check systematically (conflict between hard and space) and visually (other types of errors).
Using BIM Technology for analysis and modeling tools to evaluate the initial design scheme can increase the overall quality of the building.
Advantages of BIM Technology in design 1.
Before establishing the detailed building model, develop the scheme model to more carefully evaluate the proposed scheme to determine whether it meets the functional and sustainable needs of the building.
When the design needs to be changed, a completely consistent drawing will be generated immediately after the design modification is input.
The objects designed by BIM Technology software are controlled by parametric rules, and the model will not produce errors in geometry, alignment and spatial coordination, which can reduce the need for users to manage design changes.

3.
Synchronization of design and construction procurement a complete building model will provide accurate quantities of all (or most, depending on the 3D modeling level) materials and objects in the design.
Produce accurate and consistent 2D drawings at any stage of design.
4.
Therefore, using BIM Technology is more likely to make more informed design decisions than writing based systems.
3.
Therefore, a general (or macro) building model built in or connected to the cost database brought by BIM collaborative management technology is of great value and help to the owner.
This updating method is very easy to make mistakes in the system based on pictures.
If a relatively positive answer can be given, the owner can expect the goal to be achieved.
3.
For earlier and more accurate design visualization, the 3D model generated by BIM Technology software is directly designed by software, rather than generated by multiple 2D views.
Concept, feasibility, and design presentation When the owner requires the designer to design, it is necessary to determine the specified size, quality level, expected specification requirements of the building, and whether it can be built within the predetermined budget and time.
By applying BIM mode and fully integrating and utilizing the information involved in the whole life cycle of construction projects, it can not only shorten the time required for construction projects and save resource costs, but also help all project participants improve decision-making efficiency and design quality.
4.
The use of BIM Technology can support and improve many business practice processes in architectural design and construction process, solve higher complexity problems in the construction process, and have irreplaceable benefits to the owner, design unit and construction party.
As the design progresses, more detailed quantities can be obtained to make the cost estimation more accurate and detailed.
In addition, in the BIM system, the change design can be solved more quickly, because the modification can be shared, visualized, estimated, and solved without written communication.
5.
Capture cost estimates at the design stage At any stage of design, BIM Technology can extract the correct quantity and space list for cost estimation.
Design errors and omissions are found before construction Because the virtual 3D building model is the root of all 2D and 3D images, it can avoid the design error caused by the inconsistency of 2D graphics and images.
BIM Technology can let all parties know the costs associated with the design when the design progresses to the level of detail required for construction bidding.
At present, many product manufacturing object definitions have not been developed, so this function has not been fully implemented, but when this model can be used (steel structure, precast concrete construction, some mechanical components, and some doors and windows), the results are very helpful.
