The structural engineers decide it is needed to change some structural dimension.
Due to seismic risks, some of the structure dimensions need to be changed. The change is mandatory, but with minimum external effects. I will still notify the owner, even if there is no need for approval.
So, I think we can continue our work. We will keep you updated on how the resources will be spent, given all the new parameters.
If the costs grow with more than 5% of your initial budget, I will ask you to to cease the process until I get a response from the owner since it becomes a major change in the whole process.
