Use "one workday" as the unit of time. Include list of nonworking days and holidays incorporated <br />into the schedule. <br />C. Cost Loaded CPM Schedule Preparation: Prepare a list of all activities required to complete the Work. <br />Using the preliminary network diagram, prepare a skeleton network to identify probable critical paths. <br />1. Activities: Indicate the estimated time duration, sequence requirements, and relationship of each <br />activity in relation to other activities. Include estimated time frames for the following activities: <br />a. Preparation and processing of submittals. <br />b. Mobilization and demobilization. <br />c. Purchase of materials. <br />d. Delivery. <br />e. Fabrication. <br />f. Utility interruptions. <br />g. Installation. <br />h. Work by Owner that may affect or be affected by Contractor's activities. <br />i. Testing. <br />2. Critical Path Activities: Identify critical path activities, including those for interim completion <br />dates. Scheduled start and completion dates shall be consistent with Contract milestone dates. <br />3. Processing: Process data to produce output data on a computer-drawn, time-scaled network. <br />Revise data, reorganize activity sequences, and reproduce as often as necessary to produce the <br />CPM schedule within the limitations of the Contract Time. <br />4. Format: Mark the critical path. Locate the critical path near center of network; locate paths with <br />most float near the edges. <br />a. Subnetworks on separate sheets are permissible for activities clearly off the critical path. <br />D. Initial Issue of Schedule: Prepare initial network diagram from a list of straight "early start-total float" <br />sort. Identify critical activities. Prepare tabulated reports showing the following: <br />1. Contractor or subcontractor and the Work or activity. <br />2. Description of activity. <br />3. Principal events of activity. <br />4. Immediate preceding and succeeding activities. <br />5. Early and late start dates. <br />6. Early and late finish dates. <br />7. Activity duration in workdays. <br />8. Total float or slack time. <br />9. Average size of workforce. <br />10. Dollar value of activity (coordinated with the Schedule of Values). <br />E. Schedule Updating: Concurrent with making revisions to schedule, prepare tabulated reports showing the <br />following: <br />1. Identification of activities that have changed. <br />2. Changes in early and late start dates. <br />3. Changes in early and late finish dates. <br />4. Changes in activity durations in workdays. <br />5. Changes in the critical path. <br />6. Changes in total float or slack time. <br />7. Changes in the Contract Time. <br />F. Value Summaries: Prepare two cumulative value lists, sorted by finish dates. <br />1. In first list, tabulate activity number, early finish date, dollar value, and cumulative dollar value. <br />2. In second list, tabulate activity number, late finish date, dollar value, and cumulative dollar value. <br />3. In subsequent issues of both lists, substitute actual finish dates for activities completed as of list <br />date. <br />4. Prepare list for ease of comparison with payment requests; coordinate timing with progress <br />meetings. <br />a. In both value summary lists, tabulate "actual percent complete" and "cumulative value <br />completed" with total at bottom. <br />b. Submit value summary printouts before each regularly scheduled progress meeting. <br />DocuSign Envelope ID: 94E7997D-4F29-42F6-A9B4-0A160438D2A6
