With the push towards economy on structures today, we have designed out the inherent redundancy in our structures. The construction phase is the most difficult and dangerous phase in the life of a structure. Even if a structure is not visably damaged by local overloading during construction, damage may still occur. A proper well designed reshoring system is vital to ensure that the construction phase does not do damage to a building.
Hopefully in the coming months, ACI with publish a long awaited document on Reshoring design and analysis that will help make the desicion easier as to when to involve a specialty reshoring contractor.
As far as fees, I don't really know. My time is rolled up into an estimate, though it comes to around $100 an hour, much less if you count time spent working while off the 40 hr a week clock.
