How is the warranty period for work performed after Substantial Completion calculated?

The calculation of the warranty period for work performed after Substantial Completion is indeed based on the principle that this warranty may be extended based on the additional work performed. When additional work, such as repairs or modifications, is completed, the warranties associated with that work typically start anew. This means that if the contractor performs extra work or addresses elements that were deficient after the original Substantial Completion, the warranty for that work gives the owner an extended time frame to call on the contractor to remedy any issues.

This practice recognizes that any subsequent work could potentially have different performance characteristics or could introduce new elements that may not have been covered under the initial warranty agreement. Therefore, by effectively resetting the warranty for the newly completed work, it ensures the owner has coverage for defects or failures associated with that additional work for a defined period.
