1. Prepare schedule based on required sequence and interdependence of activities.
Logically sequence activities.
2. Prepare detailed activity network for accomplishing required work organized by Work Breakdown Structure, (WBS). Utilize WBS in lieu of activity codes for organization of schedule.

4. Meet contract requirements; milestone(s) in accordance with the clause at FAR 52.211-10, Commencement, Prosecution, and Completion of Work; funding constraints in accordance with the clause at WBR 1452.232-80, Limitation of Funds; and relevant specification sections.

dewatering, storm water management), will not be subject to workday duration limitation.
8. Include separate activities for submittal preparation and submittal reviews when submittal addresses work that involves significant quantities, long lead times, is on the critical path or near critical path, or as requested by the COR. Assign Government submittal review activities to a 7 day calendar with durations as specified in Section 01 33 00 - Submittals. Include Required Submittal Number, (RSN), in activity description.
9. Include separate activities for fabrication or manufacturing when work involves significant quantities, long lead times, is on the critical path or near critical path, or as requested by the COR
10. Include contract title, contract number, and Contractor’s name on transmittal cover sheet and each sheet of Gantt chart.
11. For each activity on Gantt chart, display identification number, activity description, planned duration, start date, finish date, total float, and calendar identification.

12. Include table of abbreviations used in the schedule, listed and defined alphabetically.
13. Use finish to start logic relationships between activities. Do not utilize start to start, finish to finish, or start to finish logic relationships. Do not use negative lead or lag times.
14. Use durations in units of whole workdays.
15. Provide best estimate of time required to complete activity considering quantity of work and planned resources for activity.
16. Equate durations of Government reviews and other identified actions to maximum number of calendar days specified in their respective paragraphs.

6. Generate Cash flow reports showing estimated monthly earned value of activities.
a. Report showing each activity cash flow for project duration.
b. Report showing cumulative monthly cash flow for project duration.
7. Generate Activity value report showing value of each activity.

B. The CO may use time impact analysis to determine if time extension or reduction to contract milestone dates is justified.
1. Time impact analysis is required for contract changes whether the Contractor’s current schedule milestone dates are the same as, earlier than, or later than, those required under the contract.
2. Changes, additions, or deletions to activities; activity durations; activity time frames; or activity predecessors and successors will not automatically determine that extension or reduction of contract time is warranted or due the Contractor.
