Hello,
we are building a house without a basement.
On the ground floor, we have a reinforced concrete slab, 25 cm (10 inches) thick. The masonry is complete, and the roof framework is currently being constructed.
Our builder wants to apply bituminous membranes onto the concrete slab before the electrician and HVAC technician lay their cables and pipes.
I have spoken with both, and the plan was for the electrician to install their wiring first, while the other service providers would follow and cut into the slab at the points where their lines cross, so the electrical cables would lie in a small recess. However, this process would damage the membrane, and the builder is strongly opposed to cutting into the slab.
His argument is that we have a total floor build-up of 20 cm (8 inches) where all the lines can fit without cutting into the concrete.
So, what is the best way to handle line crossings to avoid technical issues with any of the trades?
According to the installers, the procedure they propose is common practice.
Best regards,
André

Crossing pipes on the foundation slab or on the raw subfloor in the upper floor are perfectly normal and comply with recognized engineering standards. With detailed planning, this is fine. Unfortunately, "no randomness means no chaos" is also a recognized rule of engineering ;-)
