QUALITY ASSURANCE

Scheduler: [Contractor's personnel] [specialist Consultant] specializing in CPM scheduling with [one] [_____] years minimum experience in scheduling construction work of a complexity comparable to this Project, and having use of computer facilities capable of delivering a detailed graphic printout within [48] [_____] hours of request.

Contractor's Administrative Personnel: [_____] years minimum experience in using and monitoring CPM schedules on comparable projects.

FORMAT

Listings: Reading from left to right, in ascending order for each activity. Identify each activity with the applicable Specification section number.

Diagram Sheet Size: [24] [30] [_____] inches ([600] [750] [_____] mm) high x [[36] [_____] inches ([900] [_____] mm) wide] [width required].

Scale and Spacing: To allow for notations and revisions.

SCHEDULES

Prepare network analysis diagrams and supporting mathematical analyses using the 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".] [P.J. Burman's "Precedence Networks for Project Planning and Control".]

Diagrams to illustrate order and interdependence of activities and sequence of work; how start of a given activity depends on completion of preceding activities, and how completion of the activity may restrain start of subsequent activities.

Illustrate complete sequence of construction by activity, identifying work of separate [stages] [floors] [_____]. Provide dates for submittals [including those for Owner furnished items] and return of submittals; dates for procurement and delivery of [critical] products; and dates for installation and provision for testing. Provide legend for symbols and abbreviations used.

Mathematical Analysis: Tabulate each activity of detailed network diagrams, using calendar dates, and identifying for each activity:

Preceding and following event numbers.

Activity description.

Estimated duration of activity, in maximum [15] [_____] day intervals.

Earliest start date.

Earliest finish date.

Actual start date.

Actual finish date.

Latest start date.

Latest finish date.

Total and free float.

Monetary value of activity, keyed to Schedule of Values.

Percentage of activity completed.

Responsibility.

Analysis Program: Capable of compiling monetary value of completed and partially completed activities, of accepting revised completion dates, and recomputation of all dates

and float.

Required Sorts: List activities in sorts or groups:

By preceding work item or event number from lowest to highest.

By amount of float, then in order of early start.

By responsibility in order of earliest possible start date.

In order of latest allowable start dates.

In order of latest allowable finish dates.

Contractor's periodic payment request sorted by [Schedule of Values listings.] [specifications sections.]

Listing of basic input data which generates the report.

Listing of activities on the critical path.

[Provide sub-schedules for each state of Work identified in Section [01010] [01011].]

Coordinate contents with Schedule of Values in Section 01019.

SUBMITTALS

Within [10] [_____] days after date [of Owner-Contractor Agreement] [established in Notice to Proceed], submit proposed preliminary network diagram defining planned operations for the first [60] [_____] days of Work, with a general outline for remainder of Work.

Participate in review of preliminary and complete network diagrams jointly with Architect/Engineer.

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] [mechanical and electrical] Subcontractors have reviewed and accepted proposed schedule.

Within [10] [_____] days after joint review, submit complete network analysis consisting of network diagrams and mathematical analysis.

Submit updated network schedules [with each Application for Payment] [every [30] [60] [14] [_____] days].

Submit the number of opaque reproductions the Contractor requires, plus [two] [_____] copies which will be retained by Architect/Engineer.

****** [OR] ******

Submit one reproducible transparency and [one] [_____] opaque reproduction.

Submit under transmittal letter form specified in Section [01300] [_____].

REVIEW AND EVALUATION

Participate in joint review and evaluation of network diagrams and analysis with Architect/Engineer at each submittal.

Evaluate project status to determine work behind schedule and work ahead of schedule.

After review, revise as necessary as result of review, and resubmit with [10] [_____] days.

UPDATING SCHEDULES

Maintain schedules to record actual start and finish dates of completed activities.

Indicate progress of each activity to date of revision, with projected completion date of each activity. [Annotate] [Update] diagrams to graphically depict current status of Work.

Identify activities modified since previous submittal, major changes in Work, and other identifiable changes.

Indicate changes required to maintain Date of [Substantial] [Total] Completion.

Submit sorts required to support recommended changes.

Provide narrative report to define problem areas, anticipated delays, and impact on Schedule. Report corrective action taken, or proposed, and its effect [including the effect of changes on schedules of separate contractors.]

DISTRIBUTION

Following joint review, distribute copies of updated schedules to Contractor's project site file, to Subcontractors, suppliers, Architect/Engineer, [Owner] [and other concerned parties].

Instruct recipients to promptly report, in writing, problems anticipated by projections shown in schedules.
