August meeting followup – Drawing and Model markup options

by

Thanks to all those who attended the August meeting and to Norman Disney Young for hosting

First presentation: Round tripping Revit data through Trace

Pat Browne from NDY gave some great insights into their MEP processes for round tripping Revit Data through Trace for heating and cooling load calcs. One part of Pat’s presentation that generated quite a bit of discussion was the process of prepping the linked consultant’s models for their MEP purposes and the efficiencies that can be gained if we take the time to understand each others needs and “scrub each others backs”.

e.g. It is quite important for the heating and cooling load calcs that all walls are properly defined as Exterior on Interior. As the walls are generally in the architectural model it is there that this setting needs to be made, therefore, the architectural consultant should do it. However, this setting is mostly ignored by Architectural consultants as it has no real bearing on their output (i’m generalising here – based on the reality that most consultants are not required to produce full BIM models), but it is actually really easy to do (Edit wall type, select Exterior or Interior). Of course, if this setting is done in the right place, it only needs to be done once.

It was clear from those at the meeting that they would happily make these sort of changes to their model if they knew it was going to help someone else and raise the overall “BIM-ness” of the project.

Second Presentation: Drawing and Model markup options.

I promised to post the information I presented about some of the options available to you, your team and anyone else to review, markup and comment on your drawings and models.

Click here to download a spreadsheet summary of some of the most common options. It is by no means a comprehensive list, just what I have come across in my travels. If you have other processes or software that you use, please let me know and I will keep the list updated.

Cheers,

    I appreciated both presentations and took away some valuable learnings.
    WRT exporting information for use in external packages, the essential is to be robust, repeatable without critical user input and well documented for client trust and of course ISO auditing purposes.
    It is imperative long term however to reach a point where “translations” (export/import between software) is not required through either new standardised built in processes, third party module development (better) or even by AutoDesk gobbling up third party software companies and incorporating industry standards.
    A similar situation existed with a major project I was involved in, we chose to use ProSteel because this has well documented and proven processes to take steel framing data into an industry recognised stressing software. While Revit could do this at the time, the internal stress analysis was not accepted in industry standards, at least on this side of the world, and it would have cost a lot of time we did not have to build this process into the project. However, the costs of not being able to optioneer as much as we wished did prompt us to make the call on developing this into the next project so we had less opportunity for error and more opportunity to analyse more options next time.
