THE BIM ADVANTAGE
One of the major benefits of adopting the Building Information Modelling technology is simulating the construction process to minimize constructability issues on site. The potential clashes which are going to be there on site are predicted and the coordinated model is used to generate the drawings. This process of coordinating all the services and civil components in a 3D environment before generating the shop drawings adds a lot of value to the process of drawing generation and makes it integrated and devoid of coordination issues or human errors generated due to drafting.
Also, as all the drawings are generated from the Model, all of them are stored at one single place and problems of version management do not occur. The changes in the drawings are automatically incorporated everywhere once the change is done in the model, reducing the time taken for change incorporation to a large extent.
Therefore, the Clash free Model will be used to extract the drawings so that the drawings are coordinated and reside at a centralized location. As built drawings or shop drawings will be generated through the BIM model details and the extent of which would be decided by Client.
Changes implemented in the Model are shown in all the drawings simultaneously due to a centralized system which help reduce the clashes
The Model acts as an effective database for all the drawings and documentation at one central location, thus reducing the hassles of managing hundreds of drawings.
The co-ordinated shop drawing coming out BIM model have the advantage to predict possible clashes and resolve them before getting executed which helps in saving up a lot of time and money.
The dynamic changes and centralized locations of the drawings result in a significant addition to the productivity in the process of extracting the Shop drawings. It eliminates human errors and makes it less time consuming to manage and make changes in all the drawings.
EXPERTISE
At the initial stage of the project, the BIM process provides an edge over other conventional 2D drawing generation processes in a way which makes the drawings more reliable in terms of clashes as the process of Coordination is run before the generation of design drawings and all the visible and non-visible clashes are eliminated.
The shop drawings at the execution phase benefit specifically from the BIM process as all the changes that take place during the construction process are incorporated in the model to analyse any new clashes occuring due to the changes made and coordinating the same if needed. This continuous process makes the Shop Drawings generated from the BIM model immune to any major constructability issues. Also, the benefits of BIM extend with the provisions of centralized location, dynamic changes and enhanced productivity as described above.
Fabrication drawings are generated directly through the BIM model, saving hours of manual drafting and ensuring accuracy in the details. Model is detailed to the level of the connections, i.e. nuts, bolts and welds to ensure efficient fabrication drawing generation.
