Architects are still modeling MEP equipment in their own architectural
Revit model, even though it is a BIM project in order to be coordinated with
MEP. This method can also be argued to being not feasible, but was one I
used for coordination in a Residential Building Project.
We have been
modelling all ceiling equipment to manage ceiling layout on
Architectural BIM models, like lighting, sprinklers, detectors..etc.
Essentially Mechanic Engineers modelling these equipment into BIM model,
because of that reason we had to check all equipment if they exist or are in
the right location to be able to provide coordinated layout after every model
share.
Following this, I
decided to compare the equipment location between Architectural and MEP models
with using Dynamo.
The first problem was architectural and
MEP model's mismatches, Architect separating tower blocks and podium floors
into different model files, MEP separating different mechanical systems (HVAC,
Security System, Water Supply System, Fire Alarm...) into different model
files. The reason, I had to link all the models into one model with using
"Get elements From Linked Model" node , than catch the family centre
points.
Ensuring tolerance despite small slip.
Second problem was the "shared
coordinate data" which were different in all the BIM models. Accordingly,
I manually transferred all points in each model to the same coordination point.
Transfer the points to the Same Coordinate System
After transferring elements manually this problem solved in Dynamo Forum. There is a topic which is solved by Dimitar_Venkov It is explaining how to transfer linked elements to the "shared coordinate" location.

The link below will take you to the dynamo forum where I was helped to match close points in the model. I matched the points as you can see below in the excel sheet. If there was a point less than 1000mm away, dynamo wrote it down on the side column, if there was no point it left the side column empty. After that I could determine which location had the problem.
These clashes can be provided with this dynamo study and coordination has become easier.
Thank you for
reading.
