What role does BIM play in the construction stage?

First, and most importantly, it can help you reduce the communication cost! ! !

Communication is really the most important and patient cost besides time and money in modern society. I remember my mother's time when everything was painting. When drawing a big piece of paper, you must draw standing. In the past, you needed to hold the floor plan, cooperate with your imagination and explain it to the docking person with your impeccable tongue. When the other party doesn't understand you, or you don't understand each other, or no one knows who, what the chicken said to the duck happens, and the voices of the two people are getting louder and louder ... Even if the communication is very good, it is very easy to make mistakes, which will easily lead to carelessness in the construction stage and insufficient personnel capacity.

The communication cost becomes higher, the progress slows down, the number of rework increases, the construction cost increases, and the ineffective labor is also increasing-this is a vicious circle.

So BIM is really a treasure for liberating builders! ! Through the construction simulation of BIM, the components in the building are introduced into the BIM model according to the actual size. After BIM software simulation, the realistic gap between theoretical construction and actual construction is comprehensively considered. Moreover, after the construction simulation, the owner can find the problem as soon as possible according to the model, give feedback as soon as possible, and adjust it in time to avoid endless rework in the later period.

Second, the communication cost is low, and your working mood will be better. After talking about your mood, let's talk about life safety.

Everyone should have seen too many negative cases when they were in school, such as a case where a building had serious problems because of an engineer's slight negligence, resulting in casualties. The advantage of BIM technology is that it is now possible to establish a three-dimensional visual model through BIM technology, reflect the possible problems in engineering construction one by one through the model, and introduce the data information and attributes of building components into the model, thus improving the authenticity of model construction and improving its guiding significance. Through data comparison, a set of feasible construction scheme can be formulated, which can greatly improve the construction quality and minimize the safety risk with on-site detection and other technologies. The data will not deceive people, and the error risk brought by manual check is greater, while the efficiency of data monitoring is much higher. By the way, one of the great benefits of data clarification and content visualization of BIM here is that when there are security problems and hidden dangers, it becomes much easier to pursue responsibility ~ the person in charge will come out as soon as he checks the data, and no one will want to blame him. Ha ha ha ~ ~

Third, it is convenient for many parties to contact and cooperate.

In the process of construction, you will meet many people with non-engineering background, such as the leaders of the construction party, the supervision party and the owner. Many of them are non-engineering backgrounds, and they simply turn a blind eye to professional two-dimensional drawings, which may easily lead to misunderstandings in the construction process and obstacles in communication between the parties. I once held a document to sign for the leaders of docking enterprises and encountered many problems. I called 1 for more than hours, which explained a very simple problem! ! ! BIM model is completely visual, which can show all the links and many components in the building in front of all aspects. Everyone can communicate in a unified environment, and the process and results of construction simulation are also very intuitive. This greatly improves the communication efficiency, so that all parties can fully and timely understand the various problems and situations of the project. If you can explain clearly with pictures, you don't need words. If you can show clearly with BIM, you don't need words. This will be much more efficient.

Fourth, it is convenient to implement lean construction.

The concept of lean construction was put forward by Danish scholars in 1992. In the past, building production efficiency was low, construction conditions were poor, and product quality could not be guaranteed. Therefore, Danish scholars put forward lean construction, hoping to turn construction into excellent production. Lean construction requires very careful and systematic operation to ensure that the components can work smoothly during the construction process. BIM provides a very accurate design model, which facilitates the smooth cooperation of construction enterprises in all stages of construction, greatly reduces the probability of resource waste and the occurrence of unpredictable situations. Everyone has seen the news recently, and more and more voices are saying that protecting the world environment cannot be separated from China's support. Therefore, there will be higher and higher requirements for the efficiency of lean construction in the future, and BIM technology is a very important factor to promote lean manufacturing.

Fifth, it is convenient to modify.

The most annoying thing in the construction industry is endless changes ... without BIM, every change will make you collapse. After using BIM technology, we can not only find problems quickly and put forward the demand for design changes, but also make design changes very quickly and effectively. BIM model has the functions of automation, consistency and collaboration. When making design changes, the system will automatically modify other related information involved! This is the most awesome place in the legendary BIM-"one modification, everywhere modification"! Freshmen in civil engineering suggest that they must learn several core software of BIM first, such as Revit, Navisworks, fuzor and lumion, and then find an internship.

Six, help to quickly complete the installation and acceptance.

When we need to count the number and specific codes of the equipment entering the site, we need to know clearly which equipment is installed. Which equipment has been accepted? Whether the water pipe leaks or not must be tested, right? Therefore, in the process of construction, the Revit model should be updated in time! If the construction situation deviates from the simulation situation in the previous step. Then, the actual construction situation should be recorded in time. There is a rivet here, and there is a nail there. It is necessary to have timely updated data so that the owner, construction party and supervisor can know the progress, cost, site situation, safety and quality management in time.

After the project is completed, the owner and the supervisor will check whether it is qualified. The building will be fully operational as soon as it is accepted and signed by the owner. Then the details and data encountered in the operation process, which equipment needs to be replaced after 7 years, and how often the elevator needs to be maintained, these fragmentary information should be recorded with the as-built model. The as-built model can record data very comprehensively.
