project manager

I am seeking historical or rule-of-thumb information that sureties use in evaluating design fees. Specifically what is the history of increase in design fees if an engineer/architect is replaced on a project as surely there is a learning curve, transfer of information that needs to occur.

We recognize that if we are being asked to add on to an existing facility there is a premium of about 25% of the design fees associated with researching previous design data and matching existing details, etc. and it appears that replacing a designer on a project would have the same kind of impact.

Any resources on this subject would also be appreciated.

Thank You!

As most agents generally are not involved on the engineering end, especially when it somes to replacement of an engineer. Moreover, I don't even know if the surety would know the answer to this. I say this as many sureties outsourse their claims to construction management professionals to get a non-biased 3rd party. This way they can determine their exposure from the construction and legal front.

so, I don't know the answer to your question.....can anyone else jump in and shed some light on this question?
