Project Planning
identifying all the activities necessary to complete the project
Project Scheduling
determining the order, duration, and start/end times for each activity
What are the scheduling responsibilities of the owner?
- set the completion date
- set priorities for the project components
What are the scheduling responsibilities of the designer?
- develop the design schedule
- meet owner’s requirements
What are the scheduling responsibilities of the contractor?
- develop the activity schedule
- schedule the materials, labour and equipment
- organize the subcontractors
What are the 2 general methods for technical planning/scheduling?
- Gantt Chart
2. Critical Path Method
PERT
(Program Evaluation and Review Technique) activities are shown as a network of precedence relationships using activity on arrow network constructions
Duration (D)
estimated time to perform an activity
Early Start (ES)
earliest time an activity can start
Early Finish (EF)
earliest time an activity can finish
Late Start (LS)
latest time an activity can start
Late Finish (LF)
latest time an activity can finish
Total Float (TF)
the amount of time an activity can be delayed without delaying the project completion date
Free Float (FF)
the amount of time an activity can be delayed without delaying the early start of the next activity
Critical Path
the progression of activities having 0 free or total float
What are the 4 successor/predecessor relationships?
- finish-to-start (most practical and what we use)
- start-to-start
- finish-to-finish
- start-to-finish (fucking useless)
Lag
the amount of time that an activity is delayed from the start or finish of its predecessor
Lead
the amount of time that an activity precedes the start or finish of its successor
