“the greatest innovation and upgrade of the AusHFG information” –AusHFG Website
Along with a recent website relaunch today, AusHFG has very discretely released a Revit file containing a number of standard room layouts. With the investment they have made into developing this content, it is surprising to see there was no mention in their newsfeed about this BIM or Revit addition.
As with any content, there’s plenty of poorly developed content out there so this overview will give you an insight to see if it’s worth checking out.
A comprehensive review of this content would span pages, I have instead taken the approach of brushing over the content and providing a general overview of its appropriateness and usability.
It’s all available and downloadable for free at:
https://healthfacilityguidelines.com.au/project-resources
Naming
Although it does not seem to follow a recognised industry standard, family naming is clear, simple and void of confusing acronyms. A consistent and clear naming system is the first imperative when establishing a building information database and working the data and graphics to your advantage.
Graphics/ Documentation
Generally the families perform quite well in this regard.
Just about every element has been assigned a line weight of 1 including when cut. This tends to make the documentation look flat. Some further work is required to give the families more punch.
Masking regions could be utilised more effectively to improve the graphic display of elements with complicated geometry. Closely spaced lines and overdetailed objects tend to detract from the crispness of documentation.
Symbols are preferable for wall switches in plan rather than showing the physical object.
It is promising to see that the plan/elevation representation of families is clear to read and doesn’t consist of complex modelled elements.
Parameters
Families are parameter rich and seem to respond to the changes as requested.
With the release of the file, there was no associated release of a shared parameter file (although some parameters originate from one), instead families have been assigned project/family parameters.
I would hope that they will be addressing this in future releases and adopt an industry standard such as ANZRS.
Modelling
There is an appropriate amount of 3D geometry for most objects. 3D looks clear and rather impressive when assembled into a standard room.
Complex planning of modelling is evident through modelling practices such as creating benches using Generic models to enable joining and sinks to automatically cut.
The content does not seem to use Detail Levels so 1:200/ 1:100 and concept plans are blotchy and over detailed.
There does seem to be too many ‘single purpose’ built families, especially in terms of casework.
Excellent work on not hosting elements to walls. Most BIM Managers will agree that this is a preferred approach.
Items that are not required to be complex are modelled simply. Such as the soap dispensers.
File Size
With over 500 families released it is great to see only 1 over 1mb. A majority are around the 300-400kb mark.
With all the information and complexity in this file, it is impressive to see that it is only 140mb. Although, this could be bought down with the reduction of single use families and the sharing of nested family components.
Data
Elements have been assigned a BIMID, and are schedulable which will assist in the creation of Room Data Sheets and quality checks.
Overall, it is excellent to see that the focus has been on the parametrics and data in lieu of modelling elements to the nearest millimeter as is often touted by some ill advised content developers.
Addition of 3D and 2D clearance zones would be an added bonus to equipment and useful for clash detection.
Overall
As a first go at Revit content, well done to AusHFG, they seem to have found the right balance and have invested well into providing good quality BIM content. They are on the right track and I look forward to further refinements. This is a game changer for the industry and will provide a much needed push towards collaborative BIM.
For the next release, it would be great to see the Room Layout Sheets as presented in the AusHFG pdf, complete with tagged, noted and dimensioned elevations. Next time with the addition of live updating purpose built schedules, and 3D previews.
