## 1.02 DEFINITIONS ### A. The following terms are defined for this section and supplement the terms defined in Exhibit G of the Construction Agreement: 1. Activity: An element of the construction work that has the following specific characteristics: consumes time, consumes resources, has a definable start and finish, is assignable, and is measurable. - a. Critical Activity: An activity on the critical path of the construction schedule that must start and finish on the planned early start and finish times. - b. Predecessor Activity: An activity that precedes another activity in the network. - c. Successor Activity: An activity that follows another activity in the network. ![[Section 01 32 16.20.1.02.A.2]] 3. Cost Loading: The allocation of the schedule of values for completing an activity as scheduled. The sum of costs for all activities must equal the total Contract Sum. 4. CPM: Critical path method, which is a method of planning and scheduling a construction project where activities are arranged based on activity relationships. network calculations determine when activities can be performed and the critical path to complete the Work of the Project within the specified Contract Times and interim completion milestones. 5. Critical Path: The continuous chain of activities with the longest duration for completion within the Contract Times. 6. Early Start: The earliest possible date an activity can start according to the assigned relationships among activities. 7. Early Finish: The earliest date an activity can finish according to the assigned relationships among the activities. 8. Event: The starting or ending point of an activity. 9. Late Finish: The latest date an activity can finish without extending the Contract Times. 10. Late Start: The latest date an activity can start without extending the Contract Times. 11. Float: The time difference between the calculated duration of the activity chain and the critical path. ( a measure of leeway in starting and completing and activity) - a. Free float is the amount of time an activity can be delayed without adversely affecting the early start of the successor activity. 12. Network Diagram: A time-scaled logic diagram depicting the durations and relationships of the activities. 13. Resource Loading: the allocation of labor and equipment necessary for completing an activity as scheduled. 14. Work Areas, Area, or System: A logical breakdown of the Project elements or a group of activities which, when collectively assembled, are readily identifiable on the Project (for example: yard piping, a structure or building, a treatment process, or other logical grouping).
