BIM for Manufacturers is the new trend to automate production and Bill of Materials (BoM). Thus, Fabrication with BIM significantly reduces the risks and contingencies in a project. With the following, we will share how to save time and cost with prefabrication and manufacturing.
More and more often clients require BIM implementation into their process, for manufacturing steel structures. These prefabricated steel structures are complicated because they include lots of individual components. Also, the manufacturers have different strategic partners with engineers, they need subcontractors for assembly purposes. This means there’s a lot of information and communication going on. At the same time, they need to ensure that time and the budget are reasonable for the project owner. And last but not least, they need to make sure the architects are satisfied with the design of the structure.
In order to visualize everything in a more accurate way and to keep a sustainable supply chain throughout the project life cycle, we establish an objective to reach the maximum for fabrication, bidding, and assembly. For the fabrication we have decided to go in through complex BIM components that involve rules and constraints, so we know that these components should be used in a particular method in a lego format. This way we can quickly bring the whole structure together.
When we have the whole structure, we can easily share the 3D information for the Model with the Architect, the Project Owner, and they can evaluate how it fits their design. They are able to provide feedback and the expected amendment could be implemented very quickly. After that, the code for the Project Owner could be sent right away, because we will have the Bill of Materials (BOM), directly extracted from the nested components. Those BOMs will be very accurate. All the components that will be required for constructing the structure will be included in the BOM. Hence, the bidding process is going to be accurate and fast. Then the risk for the Manufacturer is significantly reduced because we know what input we need exactly for this Project, so he can arrange his simple chain to deliver the Project within the particular time frame and to fit in the budget.
Subcontracting and Assembly
For the subcontracting and assembly side, the fees are extremely high. The reason behind this is that the subcontractor found very complicated and a lot of information, and they did not realize how much input they will need to have for this Project. They are overloaded with so much information which brings a lot of questions to their mind.
So, what is the solution? In our Project, we took the nested BIM components and we did a construction simulation with them. Simulated the whole workflow that contains the people, resource, and timeline, and this way the “picture” is clear for the subcontractor. Now, he could be aware of how much input he needs to invest and that reduces his risk significantly and everything is transparent. The result is the bidding for assembly is much, much cheaper.
This is one of the reasons why BIM is so important and how the Manufacturer could benefit from it. In this particular case, the objectives could be set up according to the different aspects we need to concentrate on.
