Is there a difference between author's supervision and technical oversight? What does YD do?

Author's supervision involves the author verifying the compliance of the constructed project with the approved design.

 

There is also technical oversight, which involves ensuring that the work (and materials) comply with building norms, quality standards, and technical work plans.

 

Technical oversight for large construction projects is carried out by a specialist (or a group of specialists) with a background in construction and experience; in low-rise construction, it is usually the developer himself.
YD Interior Studio only provides author's supervision.
