Abstract: As Construction Schedulers for a major capital budget program within the city of Los Angeles, the Program Management/Construction Management Division has found that the practice and implementation of a Construction Management “Shadow Schedule” is advantageous to all parties involved. The purpose of this paper is to illustrate the efficiency of a Construction Management Shadow Schedule that mimics the approved Baseline Schedule and monthly updates but also takes into account concurrent field activities to provide a more precise estimate of project completion. This paper defines the function and benefits of a Construction Management Shadow Schedule and provides field examples that illustrate how the implementation of such a schedule has aided in the resolution of construction disputes and potential claims.
