I have a public project where bids came back 13.5% above the engineer's estimate. Only 2 bidders and both were above engineer's estimate and they were within 7% of one another. The public agency wants to redesign (value engineer) the construction documents to save this 13.5% about $700,000 and award the contract with these new "Issued for Construction" drawings. Is this allowed or is new bidding required? Can public agency issue construction documents that aren't the bid plans?
