ᐅ Planning / Architect, Involvement of Specialist Designers for Approval Drawings

Hello,

Our architect would like to involve HVAC and electrical engineers as specialist planners for the permit planning stage. He explained that, for example, the structural engineer needs to know what will be embedded in a concrete slab.

So you want to install a mechanical ventilation system with heat recovery. Basically, I don’t think the architect’s idea is wrong, especially if he has little experience with ventilation systems. The problem for you is that building services engineering (HVAC, plumbing, and electrical) is not yet widely established for typical single-family home construction, and as a result, it will be disproportionately expensive.

But I don’t have an electrician or plumbing contractor yet. The tender will come later. For me, this feels like a classic chicken-and-egg problem.

You don’t actually have this problem at the moment because the building services planner will work on a computer and run their software calculations. It doesn’t matter to them whether you have finally chosen an electrician or plumber. For now, the only important thing for them is to know that you plan to install a mechanical ventilation system.

Edit:

Of course, you can also have the system installer (final supplier of the ventilation system) create the ventilation plan.

So, if I understand this correctly, I either have to pay another planner or already look for the final system installer. Neither option is particularly ideal for me.

Building a house costs money and requires decisions. I don’t really understand your problem here. When you buy a car, you can’t just decide the seat color at the “wedding” (final meeting), because by then the seats are already in stock.

If you feel unable to specify the ventilation system provider right now, just tell your architect to have the structural engineer calculate using average values. That shouldn’t be too much of an issue for a controlled residential ventilation system—unless your engineer is inexperienced.

That's a really good idea. Thanks!

We had the plans for the mechanical ventilation system developed only after the building permit/planning permission and structural engineering documents were completed, by the heating installer. Our architect usually works with the heating contractor we chose and therefore probably had some experience in this area. I wouldn’t have wanted to hire a building services engineer (TGA) either. If anything, I would have gone directly to the specialized contractor.
