There are countless factors that affect the success of a BIM project. This blog is not to provide tutorials on troubleshooting Revit or content creation, although I will share my experience in those areas if I think it will be beneficial. My intent is to help BIM users have a better understanding of how a building information model is expected to operate in the modeling software, and throughout the Integrated Project Delivery (IPD) process.
BIM collaboration is unique in the fact that we actually depend on the work of the entire design team to complete our own drawings. A CAD workflow allows for one designer to manipulate another’s drawings to meet their needs. While that is possible with BIM, any changes made can only be temporary and run the risk of a coordination error spanning the entire project.
I have outlined here a basic description of what I consider when implementing BIM into a project.
A collaborative workflow is an inherent factor in any BIM project, by utilizing collaborative tools and methods we can leverage IPD to actively employ the expertise of the of every member of the project team.
Benefits of collaborative workflows:
- Reduce duplicated work efforts (Architect places the plumbing fixtures, Plumbing engineer uses those same fixtures to design the plumbing systems.)
- Reduce conflicting information in Construction Documents (Architect revises the plumbing fixture layout, Plumbing engineer sees the revision and updates his design.)
Considerations for collaborative workflows:
- Model Element Responsibility
- Communication platforms (Revit Communicator, BIM 360 Team Discussions)
- Shared Project Schedule (BIM 360 Team Calendar)
- Coordinating with disciplines using CAD
- Clash Detection
Systematic Information Management:
A Building Information Model is only effective if the embedded model information accurately reflects the final constructed building, systematic information management in a collaborative platform will reduce the risk of uncoordinated model data.
Benefits of systematic information management:
- Shared platform that contains any information that is relevant to any aspect of the project (excluding sensitive information). If I could never download a file from an email again I would die happy
- Prevent work delays due to a lack of communication. Such as forgetting to include it someone on an email.
Considerations for systematic information management:
- Administration of a collaborative file sharing platform (I recommend BIM 360 Team)
- Folder structure, organization and maintenance. A shared platform cannot be used like a personal desktop. There needs to be a clear place for all information.
- File naming conventions are invaluable. I use a list of “codes” that should be used and designations for each discipline. (I.e. Civil is 01 because they are the first discipline in a set)
- Archiving protocol
Comprehensive Modeling Plan:
In a model that multiple people are working in simultaneously, establishing a detailed modeling plan can reduce a lot of heartache further along in the project. The key to developing a comprehensive plan is to look beyond the 3D modeling and focus on how the information will be integrated into the model and how it will stay up to date throughout the project timeline.
Benefits of a Comprehensive Modeling Plan:
- Quickly collect information from the model without having to leave the model or model viewer. I keep coordination schedules for almost everything including material notes, wall types, detail components, etc.
- Create a clear model construction based on the project information. (I.e. If you are working on a hotel and you want to group the guestroom types what elements will be included in the group?)
- Promote production and collaboration for optimum design results.
Considerations for a Comprehensive Modeling Plan:
- Level of Development requirements
- Expectations for each phase of the design schedule
- Naming Conventions for views, schedules, families, groups, assemblies or anything else in the model
- BIM uses established at the beginning of the project. Will you be doing any sort of analysis? If so be sure to include a way to integrate this information.
