The Model Progression Specification (MPS) is a protocol for bringing information together from all the design disciplines, estimating and scheduling and any other aspects of a project. The whole project team probably works in separate locations and don't normally communicate effectively as a team. The MPS is a completely collaborative effort which helps overcomes these issues. It ensures each team member knows what he needs to produce, at what point and at what level of detail so the whole team can plan accordingly.
The MPS allows all the Project Stakeholders to work more effectively together, meaning the whole project can be designed, coordinated, costed and scheduled in an efficient "teamworking" environment.
We've been creating 5D models for six years now and we've seen all the issues, when we model from 2D outputs, even ones which are allegedly coordinated, we find design problems which could have been avoided.
We also work with models which have come directly from the Architects and/or Engineers and know for a fact they are often inconsistently modeled, use modeling tools which don't provide the correct output for estimating and scheduling, are badly named, etc. And for sure are not coordinated when they are all merged together.
We've worked with lots of companies and tried using their own estimating and scheduling data to link to the models and know that they don't usually fit together easily for 5D.
The MPS isn't designed to be one size fits all. It's a protocol which is put together and agreed upon by the whole team at the start of a project. Sure, a standard definition can be used on lots of projects but the idea is that per project it is defined to suit all the players, by the players.
We have learned the hard way that to get the most use out of BIM, the ideal path is for all parties to work together and agree to specification for the whole project progression.
"He who fails to plan is planning to fail" as the saying goes.
Trust me, after creating over 350 3D & 5D BIM projects, in countries all over the world over the last six years, we really do know what the problems are and want to make it a smoother process for all.
Level of Detail (LoD) is a metric that reflects information maturity and richness, not just for the model, but also for the estimate, schedule and any other project aspects required such as L.E.E.D.
Each stakeholder contributes their knowledge to each stage...to develop an evolving estimate...to hone in on the labor resources necessary to install equipment or materials. This way, as more information is known about the project, the estimate and schedule grow more and more precise.
