Abstract: This paper explores the unique circumstances of project scheduling and performing schedule delay analyses for the work of subcontractors. It emphasizes the differences between schedule delay analysis for a subcontractor in contrast to schedule delay analyses performed on behalf of contractors and owners. Because a subcontractor does not have privity of contract with the owner and other subcontractors, the courses of remedy for delays caused by others rests solely with the general contractor.

This paper is based on the practical experience of the co-authors in cost estimating, scheduling, performing delay analyses and providing expert testimony on behalf of subcontractors across a wide range of projects. This paper is also supported by research of publications with content relevant to the topic of delays to the performance of subcontractors.

The results of the combined experiences of the co-authors and research substantiates that while AACE International’s (AACE) recommended practices (RP) with respect to planning, scheduling and schedule delay analysis remain applicable, it is the preparation and execution of project scheduling and assimilation of contemporaneous documentation regarding project progress and delays at the subcontract level that are required for a subcontractor to successfully pursue a time extension or defend an alleged delay asserted by others.

This paper has not been published or presented previously and differs from other schedule delay analysis papers through being focused on the circumstances of a subcontractor.
