Most contractors and trades – mechanical, electrical and plumbing – know about some of the benefits of working with Revit, but they may be unsure of how to make the transition to a new way of creating models. Their existing processes are heavily centered around the model, so they need guidance and proof that, through the adoption of Revit and eVolve MEP, they can improve on what they do today, and their productivity and accuracy can be protected. These are some of the real design challenges businesses face:
As a response to the skilled labor shortage, how can companies become more efficient in tasks? The Revit process streamlines hanger layout/coordination, spooling (prefabrication) planning and document creation, general modeling workflows, multi-trade collaboration, and coordination. The worksharing in Revit gives the ability to reduce the number of models and delivers better collaboration and coordination between trades, even if simply for the inhouse mechanical team.
How can companies increase the level of accuracy and reduce errors for all workflows that rely on model data? Errors can typically be caused by the many DWG files that are generated for each project. Decentralization of the data requires the end user to manually rebuild files or duplicate efforts to keep the data accurate. Another example of intelligence and accuracy issues with AutoCAD-based workflows is the lack of multi-trade relationships, such as hanger association to structural objects or sleeves associating to walls and floors. In AutoCAD, these must all be managed manually, as there is no intelligence among these objects as there is in Revit.
The best example of duplication of efforts in AutoCAD is when the spooling process creates exports and duplicate DWG models. As a result, when a change is made to the master model, then the user must also edit the spool sheets or rebuild them from scratch. On a hospital, for instance, there are thousands of spool sheets to manage.
Using AutoCAD, separate DWGs must be created for duct, pipe and plumbing – and often that means for each project floor and area also. A typical AutoCAD project can require twenty models to manage. The correlation in Revit between families and ITMs to architectural and structural objects can drive better accuracy on the bill of materials. Revit automates adjustments in the model if these objects are moved by another trade the user is coordinating with, so the work doesn’t proceed using the wrong set of plans. A great example of this is ITM hangers to structure.
The challenges are certainly out there, and Revit and Revit Fabrication can deliver solid benefits over an AutoCAD-based process. As just one example, the Sheets tool can deliver a direct relationship between the model and sheet deliverables. This is in contrast to AutoCAD, where the user must create separate DWGs. The model data, dimensions, annotations, and schedules in AutoCAD cannot automatically update when they are separate files.
The “awesome sauce” that can be added to the workflow is eVolve MEP. When that happens, the benefits of Revit are extended:
- Hangers can automatically be populated for the entire model.
- Rods can be extended into the structural slab while Revit maintains the association between these objects.
- Spool assemblies and sheets can be populated automatically with annotations, dimensions and schedules. Using Revit with eVolve MEP, any change to the model automatically keeps the data in these sheets synchronized with the model.
- The annotation types needed for shop/field construction documents are provided by eVolve MEP. By using Revit tags, this data is associated to the model data and is always accurate. Since the ITM data is synchronized to Revit-shared parameters, eVolve MEP further extends the ability to deliver the right data to schedules and annotations.
