As-Built Schedules Must be Founded on Evidence from the Field

Bruce Jervis, Esq., Senior Editor 

Construction Claims Advisor


The “as-built” schedule is a common tool in support of a contractor’s claim for compensable delay. When compared to an as-planned schedule, the as-built purports to show the impact of the other party’s decisions or shortcomings on critical path construction activities. If properly prepared, this can be compelling evidence.


The problem with as-built schedules is that few contractors maintain them as they perform the work. The as-built is prepared after-the-fact in the context of a dispute which has arisen. In order to be persuasive, the as-built must be tied to contemporaneous records and testimony from individuals with personal knowledge of activities in the field.



In a recent case, a contractor’s expert prepared an as-built schedule which was not only unsupported by such a foundation but was inconsistent with certain contractor daily reports and correspondence. Consequently, the as-built lacked credibility.


I'd like to hear your thoughts on the preparation and use of as-built schedules to support, or refute, delay claims.  I welcome all comments below.
