Price escalation claims, for example from starting NTP 6 months later... - what does the contractor have to provide? Do they have to provide both subcontractor's original quotes and revised quotes - or do they have to provide just the current quote or sub-contract?
What should be given to an estimator for an Independent Cost Estimate to ensure the the claim is reasonable - the sub-invoices with quantities but with prices redacted?
check the specifications sometimes bids are locked in for a specific period of time. But I have not seen at as long as 6 months.
Yes you, your subs and the 3rd tier subs would have to provide back up for escalation
