A warranty bond, sometimes referred to as a maintenance bond, provides assurance that the Construction Manager at Risk, or if necessary the surety, will meet the contractual correction period obligations during a specified period of time after construction has been completed. C 612 is intended to be used to provide bonding for a period of time greater than one year after Substantial Completion. A warranty bond is typically not used if the correction period remains the standard one year after Substantial Completion, and the Construction Manager at Risk has furnished a performance bond.
