Price Plus Time (A+B) is a delivery method like the low-bid method. ODOT designs the project in-house or through a consultant. ODOT awards the construction contract based on the lowest combined price (A) and time/schedule (B) bid.
The selected bidder’s proposed schedule becomes contractually binding. ODOT uses the schedule for incentive/disincentive contract provisions. Meaning, if the bidder completes the project ahead of schedule, they receive a bonus. If not, they are penalized and receive a predetermined portion of the contract amount.
Price = A
Time/Schedule = B
A + (B x Road User Cost) = Bid
