Those saying it’s shoddy construction should probably wait until the reason it needs extensive rework is made known.
I worked on a job years ago where the privately owned building needed all residents to chip in a large chunk of cash because the sheet piled wall in front was beginning to fail due to accelerated low water corrosion.
The original contractor had no involvement in the sheet piled wall which was already in place and an assessment of the additional loading had been made on the assumption the sheet piled wall wasn’t subject to significant levels of corrosion (not within their scope of work).
It might be shoddy workmanship, it might not.
I will be interested in knowing what the reasons are.
Definitely, it could be design, could be structural design (although I doubt that).
Unless it's design and build the construction company won't be at fault. Designers/architects often specify suppliers for specialist materials (like that glass roof) and the builder would just build to specifications.
There could be 100 reasons.
