Abstract: When projects are affected by unexpected or as-built events such as unforeseen conditions, design errors and/or omissions, or owner requested changes, the contractor’s baseline schedule and execution plan are not typically realized.Industry recognized authorities recommend that project schedules be regularly updated with two purposes in mind: reflect the current status of the project and keep the schedule as an effective management tool.These objectives can be at odds with project specifications that prohibit revisions to the schedule unless approved by the owner.If the schedule is not kept current, does the schedule become obsolete and nothing more than a payment application tool?This paper will present an in-depth discussion of why the contractor should be permitted to keep the schedule current and the problems that result from this prohibition, as well as the owner’s perspective of not allowing the contractor to revise the schedule to include as-built events occurring during project execution.Possible risks that the parties can be exposed to in these situations will also be identified and discussed.Finally, this paper will present proposed solutions for the parties to consider, which attempt to satisfy the specification requirements and keep the schedule as an effective management tool.
