From the start of the project until the award of the construction contract, the Project Engineer maintains a set of project records. These are organized and indexed according to the Project Development Uniform Filing System. From construction award to final closeout, the Resident Engineer maintains a set of project records that are organized and indexed according to the Construction Organization of Project Documents. These filing systems address one of the most error-prone aspects of project communication � communication over long spans of time.

The future recipient must know where to find the deliverable and understand previous project decisions, even if the task manager and other project team members are no longer available.
