Here are some overhead views of the model for the space. The first one has the new configuration and the octagonal tables. The second one has the new configuration but keeps the current big table instead of the octaginals.
As you can see the octagonal tables leave less than the 3 foot ADA minimum clearance for pass through. I tried multiple configurations but there isn’t a way to make it work that I have been able to find. This design has an additional issue that there is nowhere for the slab roller. The only option would be to attach it to the end table away from the doors. I haven’t modeled this yet because I don’t have the measurements for the slab table as a standalone item. Likely this would create additional ADA clearance issues if it juts out into the space.
With the current table we are able to get around ADA clearance in all places and retain the slab roller without obstruction. The table measurements includes the slab roller.
In both layouts it was necessary to put the wheels along the side to maintain the clearance from the new shelf placement. This seems to work well as long as there isn’t an issue with people sitting in the lane while they are working.
Just so everyone understands what I am talking about with ADA clearance. It comes from section 403.5.1 Clear Width. the clear width of walking surfaces shall be 36 inches (915 mm) minimum. This is specifically for wheelchairs, however it’s also used in design as a basic guideline for usable space. The old design didn’t follow this and that’s a big part of why it felt so terribly cramped.
In my opinion the best option is to keep the table we have for now. It opens up the space, it keeps the slab roller, it saves money and it’s ADA compliant.
I’ll be at the makerspace with my VR computer on Wednesday after 7 if anyone wants to get into the space in VR and see how they each feel.
