GRMC provides Digital Prefabrication and helps clients to get real-time examination of every system, making up the final project.
By having all the prefabricators’ information in the BIM model from the beginning of the building cycle there will be a reduction in costs and errors, improving efficiency.
Prefabrication makes objects easier to produce and assemble; it can be done in less time, so it is less expensive. As a result of the simplicity, the number of errors is reduced as the quality improves.
If we are using prefabrication combined with BIM, it is especially important that prefabricators take part of the designing process from the first stages of the project. If we do so, the saved time will be huge. When prefabricators are not involved in the process from the first stages (where architects’ decisions are taken), some information will not be accessible for them, creating inefficiencies.
But at this moment it is a common practice not giving the proper consideration to the activities involved in the next phases. To solve this problem, prefabricators should include all the digital information of their products during the early stages.
And it is here where most work should be done, making possible the availability of prefabricated components in digital format, so they could be used in the design, the offsite construction and the maintenance stage.
By having the manufacturers’ digital models of the components included in permanent libraries, the time saved increases hugely. For that purpose, BIM has a core database which helps to coordinate between the different agents involved in the process: designers, architects, suppliers and engineers.
BIM includes all the geometric information about the different parts of the building, but it also allows introducing ones such as cost, thermal values, resistance or acoustics. That is the interesting feature of BIM, because it can be used by many sectors involved in the development.
We can say that the most effective use of BIM models was for design coordination and walk-through animation. The greatest challenge of using BIM in construction projects is the implementation of the process itself, because development of BIM process requires huge knowledge of construction methods and processes.
Use of design model as basis for fabricated components: If the design model is transferred to a BIM fabrication tool, it will contain an accurate representation of the building objects for fabrication and construction.
- Quick reaction to design changes
- Synchronization of design and construction planning
- Better implementation of lean construction techniques
