An MPS and BIM Execution Plan Work Side-By-Side
It is easy to get overwhelmed when you hear the words BIM Execution Plan or Model Progression Specification. They both imply a dizzying array of requirements and a backlog of modeling.
Many people ask us, "Which is more important: to have a BIM Execution Plan in place or the Model Progression Specification?"
To us at Vico, it isn't a question of either/or, but a necessity for both. Your BIM Execution Plan will highlight how to handle, store, and share your BIM models. It will offer protocols to name your models, to combine multiple models, to communicate issues to internal or cross-company teams, to manage versions of the model, etc.
In contrast, the Model Progression Specification is designed to pre-plan how you develop your model and the organize the downstream activities of coordination, scheduling, and estimating. Your firm may have one or two BIM Execution Plans, but an MPS for each project.
The organizational rigor of the Model Progression Plan actually makes it easy to execute. How so? Your team completes only small chunks of modeling, estimating, and scheduling at a time. Think of the analogy of a bingo card and use the table below - you're looking to develop a Level of Detail 200 for a foundation, you simply need to pull together:
M2: the building elements with the approximate dimensions (these might be from the schematic drawing set)
E3: you'll need massing driven ratio and ranges for the estimate
S3: you'll need element-based average production rates
(If you are doing energy analysis or LEED points as part of your Model Progression Specification, you would simply gather their MPS-defined Classes to the mix.)
As soon as you have these pieces organized - BINGO - you've got yourself an LOD 200 foundation. And pulling the building elements out of your 5D Data Pack makes it even that much easier.

You might want to design MPS templates for different project types - like a museum MPS would be very different than a medical laboratory MPS - but your firm has the flexibility to do both. This makes the MPS much more versatile AND robust.
Don't get overwhelmed - get organized - the MPS helps you do that. An MPS Workshop is part of the Vico Customer Success Plan - this executive education session establishes terminology and framework for the MPS and the instructor leads the team through the creation of example content. Once completed, the team will can extend the MPS content to address their project.
Your BEP isn't complete without an MPS! So let's get started today!
