Hi,

Ive worked on a number of large, live Revit projects over the past 3 or 4 years, but I'm looking to really push the theoretical boat out and create a single, overlapping 'Jenga style' mixed-use, mega complex that I can use to compliment my upcoming BIM msc.

My idea, setting up the project using Revit, is that the site will use a Master Site File as the anchor for shared co-ordinates, this M.S.F will act as the container for the overlapping jenga blocks/building models (retail A, retail B, retail C, resi A, B, C, leisure A, B, C and so on... ) to plug into and will publish the global co-ords to each building. So there will be perhaps 10 - 15 individual isolated building models in total, plugged into a Master Site File so that separate 'teams' could work on each one individually. Isolating the models to then plug them into the central model when I want to see the project coming together in its entirity should also keep them trim and more manageable...

so. . . .

. . . As this is somewhat uncharted territory due to its size and complexity, ive been considering the most viable way to go with regards to setting up the project, this does however raise some interesting points:

1) Since the model itself will be split into 10 to 15 interlocking jenga blocks, Hierarchically im assuming each building will actually BE a central model, which will then be linked into the master scs and acquire its co-ordinates from there? Each building will have its specific project base point but be linked via the Master Sites shared co-ords?

2) If the blocks are interlocked in both the vertical and horizontal planes, how would be the best way to manage the interfaces between two vertically or horizontally adjacent blocks?


Been thinking about this for a while so im interested to hear your views.


Cheers

Welcome on your first post!

You have the right approach. This does sound like a big undertaking, but we're doing this exact thing at our office now. The project is 10 million square feet and is made up of 10 pieces. Each piece has minimum a structural model and an architectural model. Every single model is a central file and they are all linked to and use a master site file shared coordinates. You are correct that it gets tricky at the building interfaces. We have all the relevant buildings linked into each other and teams have to clearly delineate scope of work. An overly simplified description of our project is 8 high-rise towers on a large retail podium. The trickiest interfaces are when the tower cores penetrate the podium and have lobbies and other program that spills into the podium. As long as each team is clear about their scope of work, this is a good solution.

Hi, thanks Damon!!

Yeah, it seemed to be the most logical approach (as far as I'm aware) to keep everything lean and mean, also a good way to imbue some flexibility and ownership amongst the team (currently made up of favourite artists and historical figures), the 'plug-in' format works so well in other areas it makes sense to apply it to large complex projects. I know its a bit of a monster undertaking, but I usually think 'in at the deep end' is the best way to go to really test a theory or framework, especially with uni coming up this next week its gonna be great to have something to apply the theory to, even if it is just a revit model.

Like you say I guess the Interface issue is really just about co-ordination, trying to introduce delineation during massing and develop some system of ownership, but allow some flexibility, as we all know, things change!! :-)

Do you guys use Navisworks or Revit for your central model? I'm looking to get more practice on Navisworks so i'm wondering if I should set up using that just to broaden my experience a little?

Cheers for the reply, looking forward to contributing to the forum much more in the near future!

Have a read of Lonnie Compton from AU for the last few years. Also some of my recent threads are about mega projects. What you're talking about has been done before. I'm working on a federated model of about 60 central files covering 300,000 m2
