Criticism of the ASCE Schedule Delay Analysis Offsetting Delay Concept


Offsetting delay is considered questionable and biased in the direction of contractor’s interests.

The idea of offsetting delay is that an owner might be called to grant the contractor a time extension for an owner-caused, non-critical-path delay at any point during the project. This element to consider of the overall concept changes what has long been one of the basic laws of time extensions – the contractor is only permitted to a time extension to the project completion date if an excusable delay causes a delay of the project’s critical path and completion date. This white paper reviews key terms and aspects of the ASCE offsetting delay concept.
