Hello everyone,
I hope that I am in the right place with my matter and look forward to your expert help.
I am currently having the beam ceiling renovated in an outbuilding (officially commissioned carpenter). The clear size of the room is 4.5 x approx. 7.5-8.0 m (the gable is not perpendicular to the building direction).
Previously, there were beams 16x18 (span 4.5m) installed at a distance of approx. 1m with a supporting beam 18x18 and covered with boards. New beams were to be installed and clad with 28.5mm tongue and groove boards. The carpenter has now installed beams 14x24 (same span) at a distance of approx. 53 – 65 cm, without supporting beam and has not yet laid the tongue and groove boards (see picture).
When checking the beam layout (3m straightedge + tape measure), I found that at one point the outer beam lies 1 cm lower (see picture) than the third to last (approx. 1m length). At other points there are height differences as well, but less than 1 cm.
Furthermore, the complete beam layout from one wall to the other in the longitudinal direction of the beams shows a height difference of approx. 2.5 cm (see picture) over 3m length measured (3m straightedge + spirit level + tape measure). Over the entire width of the room of 4.5m it will probably be 3.5 cm.
Question 1: Are such height differences permissible?
Question 2: Which regulations govern the tolerances when constructing a beam layout?
Question 3: Shouldn't the carpenter have compensated for the old misalignment if, for example, the building has shifted slightly over the centuries? Or at least asked the client upon discovery how to proceed?
Question 4: Is it possible to lay the 28.5mm tongue and groove boards without problems with such height differences, or should I expect some consequential damage?
It is only an outbuilding, but the floor should run reasonably level and not have waves. Maybe I have too high quality standards, which is why I would like to inform myself first before confronting my carpenter with this.
Many thanks in advance for hopefully numerous comments,
Waldemar
