EMAIL Question/Answers:

Q: Was the site visit to the Eagle Creek Suspension Bridge Removal & Disposal Project that was held on November 9, 2017 mandatory?

A: The site visit was for the benefit of prospective bidders and was not mandatory.

Q: I have a couple of questions about bonding and insurance requirements. This project would require us to sub out the crane work as well as possible salvage. could you clarify what would be needed for our company as well as the subs.

A: Bond requirements vary based on contract price, please reference FAR 28.102-2 for specifics.

As for Subcontractor work, all work/requirements flows through the Prime contractor, payments, bonding…etc. It is the Prime Contractor responsibility to make sure their subs are capable of performing. Also, I assume you know that the prime contractor has to perform more than 50% of the contract.
