  1. Today’s Thoughts • If you shoot at nothing, you will surely hit it. A successful person is goal oriented. • A person who cannot see the ultimate will become slave to the immediate

  2. CON 371 - Project Management and Safety Project Scheduling 17 September 2001

  3. Project Management

  4. Why ProjectPlanning? • To think it through on paper • Method, time, resources • Identify problems and opportunities • Do not have to commit resources first • Gathering Information (planning) reduces risk

  5. Why ProjectPlanning? • Establish a framework • Measuring • Reporting • Controlling • Main parameters of the problem • What • How and when • First and next


  6. Scope Definition • What work is to be done? • Fixed Price - well defined with contract • Design/Build - may be more open • Services to be performed • Documents to be produced • Description, Responsibilities, Available Material, Decisions made

  7. Safety Budget Completion Time Reliability of operations Quality Security Use of local suppliers Use of local subcontractors Maintainability Project Objectives to consider during Scheduling

  8. New Technology Prototype Equipment Site Conditions Resources Permits Access Labor Economic conditions Startup of Complex systems Material delivery and storage Identify Unique ProblemsHow do they affect the schedule?

  9. Project StrategyImplemented thru the Schedule • Project objectives - ultimate destination • Project Strategy - general direction and how to get there, sequencing • Planning - implementation of strategy • specific work packages, schedule • What-if scenarios

  10. ConstructabilityImpact on the Schedule • What is the best way to construct this project? • Arrangement of laydown yards, sequence of construction, construction techniques • Start as early in the life cycle as possible

  11. Scope Objectives Assumptions Constraints Pending Decisions Alternatives Unique Problems Execution Strategy Staffing Work elements Project plan Schedule Budget Closeout Execution Plan

  12. Performance Assurance Plan • Project Monitoring • Schedule • Budget • Productivity • Quality • Determine baselines • Frequency of verification • Feedback

  13. Project Logic • Start planning the sequence of work • Initial operations • site layout, temp utilities, labor, modularization • Construction • order of field work, material delivery, testing and startup, • Priorities • Support for sequence, procurement

  14. Task Identification Sequencing Logic Diagram Staffing Analysis Activity Durations The Critical path Resource Profile Resource Leveling Scheduled Plan Bar (Gantt) Charts Scheduling the Work

  15. Network Logic • Sequence of Activities • Predecessors, Successors, Concurrent • Depends on method of construction • Restraints (Constraints) • Space • Resource • Equipment

  16. Project Scheduling • Activity Duration • Deterministic • Probabilistic • Estimating Durations • Scheduling Calculations • Forward Pass • Backward Pass • Critical Path • Float • Resource Leveling
