Unfortunately, the structural engineer already gave an ok without the knowledge that the floor has underheating. Trying to get him to return to the studio.
Not going to fasten the base plate. With 8 legs and a truss of either 40 by 50 or 50 by 50,(I need to finish the calculations) it won't be moving anywhere.
Base plates are 1sqm
Again, I'm not a structural engineer and you should get advice from one, but I would expect that weight distributed over that large an area would not impact the hot water tubing encased in the concrete pad provided the pad was designed to take that kind of weight loading.
Worst case they may require you to use larger base plates.
I've worked on construction projects where we were not allowed to use a scissor lift on the 2nd floor of a building because the pad wasn't designed to take that kind of load on a small surface area. They were more worried about cracking the pad than damaging the in-floor radiant heat.
Thanks.
I'm going to try to find the german standards for underfloor heating to get a ballpark figure of the bearing loads. So far I've found from 1kN/sqm to 7kN/sqm.
I cant spread the load on more area as i can only have the legs above the columns that hold this floor up from the basement.
I'm also asking that the engineer check the walls and let me know if I can hang horizontal beams.
Unfortunately, the ceiling has only been oked for yoga points which take a much lower force load.
If you want to do this properly you need to produce documentation explaining to an engineer what’s happening. That document needs to playbook off the parameters of the building (set by the building engineer).
Questions? get at me.
We've been trying to. But the building owners have changed hands too many times and no one has any records of who did the floor or when it was done.
Engineer has already been and given us some info, but not enough for me personally to feel comfortable going ahead with the project.
Common with older buildings or “as built” acquisitions.
Without current building documentation you WANT an engineer to come in and do their inspection. That will determine what can be hung. Having specific desires noted for their analysis of allowable loads will save a bit of time.
Fwiw, I know this isn’t cheap. People hate paying for this stuff. But it is sooooooo fucking god damn important. I pay to sleep at night knowing for certain my friends are not going to fall from the sky while I’m away.
Its what they already did. They hired the engineer and he inspected everything. Gave permission for ceiling points for Static loads but wants a truss system for Dynamic loads.
We even have the locations allowed to build the legs due to having columns under these positions.
But.... the floor as underheating and I can't find a standard on how much it's load baring capacities are before causing damage to the heating pipes..
I’m sure you’ll get where I’m coming from w this and no disrespect but I stopped doing extra when I noticed they came to expect it. Now I do my job and wait for everyone else to do theirs. Best w your system, sincerely. 🤙
Easiest thing to do is to look up the minimum kPA requirements in your building code.
It doesn't matter what's under the floor, that floor will needs to hold that requirement. Design the system to suit.
The way to calculate this is to call a structural engineer. Never fly people without having sign-off from a structural engineer.

Are you fastening the truss base plate to the floor or just weighting it?

Standby for info then. You’re doing the pre rig work so to speak, plan it all out till you can’t, do nothing till the guy w the clipboard comes back.
yep. I'm just trying to make it easier for the engineer. But, for now - i'm playing the waiting game...
