Abstract: Our pipeline operations group executes approximately 100 maintenance projects per year. To better plan activities and allocate resources for these projects, an enterprise schedule was needed. Projects consist of two major phases: design and construction and range in cost from $50k to $17M. The organization performs the surveying, engineering design, drafting, major procurement, land and natural resources permitting, preconstruction activities and is responsible for creating and maintaining this portion of the project. Construction activities are out-sourced and contractors are responsible for creating and maintaining the construction schedule within the contractual terms and conditions and are monitored by the company. These construction schedules are also incorporated into the enterprise schedule as they are developed. This paper will discuss the process used to develop an enterprise schedule and how this schedule is used to manage a portfolio of maintenance projects.
