Correct. Design flaws and errors you sure can, but engineers aren’t usually out there bolting them together.
Well, we engineers also need to consider assymbly concerns in the any design. I am not familiar with this issue, but if bolts are not accessible, then the design needs to be partly to blame.
That said, once the issue is known, ground the plans and reconsider the design and the assembly and the insperction.
This is a serious issue and not something you leave up to people who are not the best at what they are doing.
