1.03DEFINITIONS
.ABaseline Schedule -The Contractor’s initial CPM Progress Schedule presenting an orderly and realistic plan for completion of the entire Work of the Project. When accepted by the Owner’s Project Manager, the Contractor’s Baseline Schedule becomes the initial version of the Official Progress Schedule. The Baseline Progress Schedule is prepared in chart or graph format, consistent in all respects with the Contract Time(s) and order of Work, presented in sufficient detail to show the chronological relationship of all activities of the Project including but not limited to planned starting and completion dates of various activities, submittal of Shop Drawings and Product Data, procurement of materials and equipment, and deliveries of materials and equipment.
.BCPM Progress Schedule – The Contractor’s Progress Schedule prepared in CPM Precedence format using the scheduling software required by Section 01320.2.01, “Scheduling Software.”
.CCritical Path -The set or sequence of predecessor/successor activities which will take the longest time to complete. The duration of the critical path is the sum of the activities' durations along the path. Thus, the critical path can be defined as the longest possible path through the "network" of project activities. The duration of the critical path represents the minimum time required to complete a project. Any delays along the critical path would imply that additional time would be required to complete the project.
.DFloat – The number of work/calendar days an activity can be delayed without impacting the project completion date. The Project “owns” float.
.EOfficial Progress Schedule - The Contractor’s Progress Schedule and all revisions and updates thereto, accepted by the Owner, in accordance with the requirements of the Contract Documents.
.FPreliminary Contract Schedule - The Contractor’s CPM Progress Schedule presenting its detailed sequence of early operations including procurement of materials and equipment for a minimum of ninety (90) Days from the official Contract start date stated in the Notice to Proceed. The Preliminary Contract Schedule must also present all Milestones, sequences, and activities occurring during the entire Contract Time that are specifically required by the Contract Documents to be shown on the Contractor’s Preliminary Contract Schedule.
.GRecovery Schedule – Contractor’s detailed schedule indicating how Contractor intends to recover lost time.
.HRevised Official Progress Schedule –Contractor’s written request to revise the current version of the Official Progress Schedule. If the Owner accepts the Contractor’s request to revise the Official Progress Schedule, it becomes the new current version of the Official Progress Schedule.
.IShort Interval Schedule - The Contractor’s fourweek schedule showing the past week, the week submitted, and two weeks thereafter. The Short Interval Schedule must correlate with the current version of the Official Progress Schedule and reference the appropriate activity numbers. The Short Interval Schedule must indicate the actual start and finish dates of all activities on the Official Progress Schedule that are started or finished during the time period encompassed by the Short Interval Schedule.
.JUpdated Official Progress Schedule – The current version of the Official Progress Schedule updated to include the actual start and finish dates of activities and the percentage of completion of each activity. Actual start and finish dates must be identical to the actual start and finish dates indicated on the Contractor’s Short Interval Schedule submissions.
.KNetwork Window – Also know as “fragnets” or “hammocks”, Network Windows must be provided as needed to 'explode' a section of the Official Progress Schedule to show the effects of proposed changes or delays to the schedule.
PART 2 -PRODUCTS
