1.5 SCHEDULES
A. Prepare network analysis diagrams and supporting mathematical analyses using Critical Path Method, under concepts and methods outlined in AGC's "The Use of CPM in Construction - A Manual for General Contractors and the Construction Industry".
B. Illustrate order and interdependence of activities and sequence of work; how start of given activity depends on completion of preceding activities, and how completion of activity may restrain start of subsequent activities.
C. Illustrate complete sequence of construction by activity, identifying work of separate structures or facilities. Indicate dates for submittals and return of submittals; dates for procurement and delivery of critical products; and dates for installation and provision for testing. Include legend for symbols and abbreviations used.
D. Mathematical Analysis: Tabulate each activity of detailed network diagrams, using calendar dates, and identify for each activity:
1. Preceding and following event numbers.
2. Activity description.
3. Estimated duration of activity, in maximum 7-day intervals.
4. Earliest start date.
5. Earliest finish date.
6. Actual start date.
7. Actual finish date.
8. Latest start date.
9. Latest finish date.
10. Total and free float; accrue float time to Owner and to Owner's benefit.
11. Monetary value of activity, keyed to Schedule of Values.
12. Percentage of activity completed.
13. Responsibility.
E. Analysis Program: Capable of compiling monetary value of completed and partially completed activities, of accepting revised completion dates, and recomputation of scheduled dates and float.
F. Required Sorts: List activities in sorts or groups:
1. By preceding work item or event number from lowest to highest.
2. By longest float, then in order of early start.
3. By responsibility in order of earliest possible start date.
4. In order of latest allowable start dates.
5. In order of latest allowable finish dates.

B. Participate in review of preliminary and complete network diagrams jointly with Architect/Engineer.
C. Within 20 days after joint review of proposed preliminary network diagram, submit draft of proposed complete network diagram for review. Include written certification that major Subcontractors have reviewed and accepted proposed schedule.
D. Within 10 days after joint review, submit complete network analysis consisting of network diagrams and mathematical analysis.
E. Submit updated network schedules with each Application for Payment.
F. Submit number of opaque reproductions Contractor requires, plus three copies Architect/Engineer will retain.
G. Submit under transmittal letter form specified in Submittal Procedures, Section 01330.
1.7 REVIEW AND EVALUATION
A. Participate in joint review and evaluation of network diagrams and analysis with Architect/Engineer at each submittal.
B. Evaluate project status to determine work behind schedule and work ahead of schedule.
C. After review, revise network diagrams and analysis incorporating results of review, and resubmit within 10 days.
1.8 UPDATING SCHEDULES
A. Maintain schedules to record actual start and finish dates of completed activities.
B. Indicate progress of each activity to date of revision, with projected completion date of each activity. Update diagrams to graphically depict current status of Work.
C. Identify activities modified since previous submittal, major changes in Work, and other identifiable changes.
D. Indicate changes required to maintain Date of Substantial Completion.
E. Submit sorts required to support recommended changes.
F. Prepare narrative report to define problem areas, anticipated delays, and impact on schedule. Report corrective action taken or proposed and its effect including effects of changes on schedules of separate contractors.
A.
1.9 DISTRIBUTION
