traditional construction between Architect / Engineer & BIM

[andrew.boardman1]

What would be the correct work sequence for a traditional construction building,
ie load bearing masonry, trussed roof, block & beam floors.

We are structural engineers and working with an Architect on a traditional scheme in Revit 2013, which must be done as BIM project.

The main elements we are concerned with are foundations, lintels and a few steel beams & pad stones.

We have tried to use the architects model and causes a problem.

When we want to align steel beams to Architects walls, but it does not seem possible to monitor the wall with the steel beams and thus we are unable to monitor if the wall moves. – Do we need to copy/monitor the walls that need support or all the walls (what happens when architects change walls.)

Do we then extend the copy/monitor walls down to a suitable foundation – the architect has drawn his walls to floor level only.

Again do we just model lintel & pad stones on our copy/monitor walls.

How does the architect link to see our modifications and does he alter his walls to suit.

Do we use worksets for new steel and copy / monitor walls

my thoughts would be just alter the architects model for the limited structural elements and add a foundation and not use the copy / monitor

Any feedback would be useful thanks,

You should go to autodesk university's online classes (free) and search for multidiscipline coordination. There are many white paper pdf's that autodesk university has published about best practices for working between disciplines. Also sounds like you guys did not have a BIM kickoff meeting...consider having one on your next BIM project alot of this would be cleared up in that initial meeting.

How are you using the architectural model, is it linked into your model, are you all working within the same model? Answer this and many of your questions will be easier to answer.

Copy monitor should be used sparingly- ie. grids, levels. Copy monitor is generally used only for these things as the more you copy monitor the larger the file gets.

basic workflow is something like this:
Architecture creates Revit model
Structural copy/monitors structural elements, grids and levels
Architecture deletes duplicate elements
MEP starts populating model


here are is a thread which may be useful in learning more about this workflow:

thanks for the information and the link and i will have a read some of the papers We will make sure we have the meeting. (this is the first time us and the Architect are doing a combined bim project)
We first opened the architects model and made a template to ensure that we have the same walls. Architect only did the model down to ground floor level and no foundations/sub levels.
we linked in the architects model
we copy/monitor the levels/floors
As this is a traditional construction there is no steel frame, and there is no grid , we need to model a few steel beams, window lintels, foundations, roof construction

its load bearing masonry. therefore do we have to copy/monitor all walls. in order to do the lintels and to check if walls/windows move.
if i align a grid to the walls , will the grid line monitor the wall? steel beams (not on a grid) are unable to monitor a wall over we tried this,
