Lessons Learned (Step 3) – Schedule Development Using Primavera P6

STEP 3 – DEVELOP SCHEDULE LOGIC
by Charlie Jackson (Hill International) & Hannah E. Schumacher (Kitchell Contractors)

Abstract: Many Contract Documents are now requiring the use of the latest version of Primavera software (P6™) due to its enterprise capabilities and its use of latest technologies including the capabilities to interact other software applications; therefore it is important for the Scheduler to understand how to use this software most efficiently in their battle to complete their projects in a timely manner.

Primavera’s latest release of P6™ contains many features that can assist in developing schedules quickly and efficiently. However, a new or in-experienced user would be overwhelmed in the struggle to prepare the schedule using P6™ and these advanced features without proper training or “Basic Training”.

This paper will focus on the authors’ experiences and their lessons learned regarding the effective use of P6 ™ in the schedule development process as they apply to the TCM Planning and Scheduling development processes (TCM 7.2).

AACE International’s Total Cost Framework (TCM 7.2) outlines the twelve (12) steps for Schedule Planning and Development as follows:

  1. Plan for Schedule Planning and Development
  2. Identify Activities
  3. Develop Activity Logic
  4. Estimate Durations
  5. Establish Schedule Requirements
  6. Allocate Resources
  7. Optimize Schedule
  8. Establish Schedule Control Basis
  9. Review and Validate Schedule
  10. Document and Communicate Schedule
  11. Submit Schedule Deliverables, and
  12. Develop and Maintain Methods and Tools. [1]

Develop Schedule Logic

Once the activities have been defined, the next step is to sequence the activities.  Sequencing activities is “the process of identifying and documenting relationships among the project activities” [2].  “Logic addresses the sequential dependencies between activities, and similar issues such as programmatic, procedural, and physical requirements and constraints, and preferential sequencing in consideration of cost or resources” [1].  Recommended practice is that “logic development is an iterative planning process.  This process is further refined during the schedule development and optimization” [4].

Every activity and milestone in the schedule (except the first and last) must have at least one predecessor relationship and one successor relationship.
