6. Increased competitiveness: BIM has made it easier for smaller companies to bid on larger projects since it reduces the need for excessive resources like specialized software or trained personnel. This has increased competition among bidders, potentially resulting in better pricing for clients.

Overall, the adoption of BIM has changed traditional methods of bidding on construction projects by promoting accuracy, efficiency, collaboration, and competitiveness among bidders.

19.What is Federated BIM and how does it differ from traditional BIM workflows?


Federated BIM refers to the integration of multiple Building Information Models (BIM) from different disciplines or stakeholders into a single federated model. This approach combines individual models from different domains, such as architectural, structural, and MEP (mechanical, electrical, and plumbing) systems, in order to create a more comprehensive and coordinated project model.

In traditional BIM workflows, each discipline creates and manages their own BIM model without coordination with other disciplines. The models are only brought together at various stages of the project for clash detection or coordination purposes. This can lead to inconsistencies and conflicts that may result in delays or additional costs for the project.

On the other hand, Federated BIM allows for real-time collaboration between all stakeholders involved in a project. All models are integrated into a centralized federated model that is accessible by all parties, promoting better communication and efficient coordination among team members. This workflow helps identify potential issues early on in the design process, reducing downstream construction errors.

Additionally, Federated BIM enables information exchange between different software platforms used by different disciplines. This ensures that all models stay up-to-date with the latest changes made by each individual team member.

Overall, Federated BIM can improve project efficiency and reduce errors by facilitating better communication and coordination among stakeholders throughout the entire project lifecycle.
