Level 3 Schedule:

L3 Schedule is the Project Coordination Schedule (PCS) and also called Publication Schedule. Initially developed as an integrated CPM (Critical Path Method) overview of the project, the Level 3 schedule is then maintained as an integrated roll-up or summary of the Level 4 schedule activities for reporting status to Senior Management and to report monthly status to major project parties, etc.

The schedule consists of a set of integrated Level 4 schedules, these schedules are based on Critical Path Methodology (CPM) and developed with detailed input from the project management team. It is usually developed by the ‘Main Contractor’ as a part of its tendering process for the project or by the project team during the initial phases of planning.

The Level 3 schedule spans the whole of the project and is used to support the monthly report. It includes all major milestones, major elements of design, engineering, procurement, construction, testing, commissioning, and/or Operation.

If the Level 4 schedules are primarily developed by trade/sub-contractors, during the initial phases of the project, the Level 3 schedule provides the schedule framework and constraints used by the subcontractors to develop their tenders.

During the execution phase of the project, this schedule defines the overall critical path and it is the primary coordination tool for the overall project. Audiences for this type of schedule include (but are not limited to) Project Managers, CMs or Owner’s Representatives, Superintendents, and General Foremen.
