Lane Occupancy – When a Contractor occupies a lane(s) in proceeding with their work. The Contractor will pay a Lane Occupancy Charge (per direction) for the period of time a lane is unavailable to the traveling public beyond the allowable lane closure time limits.

Late Dates – “Drop dead dates”. The latest an activity can start or finish without effecting the end date of the project. Calculated by the computer during the backward pass.

Milestone - A type of activity used to represent the beginning or the end of a major stage, or an important event in a project. Start and finish milestones cannot have durations.

Predecessor - An activity that must occur before another activity. A predecessor activity controls the start or finish date of its successors. An activity can have multiple predecessors.

Preliminary Schedule – Initial schedule prior to the baseline schedule reflecting how the contractor plans to proceed with constructing a project.

Recovery Plan – Contractor’s plan to bring the project back on schedule. This includes a revised CPM schedule and additional manpower and equipment.

Relationships Types

Finish to Start - The successor activity can begin only when the current activity completes Finish to Finish – The finish of the successor activity depends on the finish of the current activity

Start to Start – The start of the successor activity depends on the start of the current activity Start to Finish – The successor activity cannot finish until the current activity starts

Remaining Duration – The time needed to complete an activity.

Successor - An activity that must occur after another activity. An activity can have multiple successors, each with a different relationship to it. Every activity must have a successor except the project’s finish milestone.

Time Impact Evaluation (TIE) Form DC-186 - A form provided by the NJDOT that facilitates a simplified analysis procedure used to award Contract Time due for delays that were not the responsibility of the Contractor. A fragnet is associated with the modeling of the effects of the delay. A CPM schedule that is able to show the pure CPM calculation differences between a schedule that does not include a delay and one that does include a fragnet modeling the delay. The difference in Contract Time between the non-impacted schedule and that of the schedule with the impact is considered to be the impact of the delay for a potential Contract Time extension.

Total Float - The amount of time an activity can be delayed without delaying the project finish date.

Updated Schedule – A schedule that truly reflects the current means and method how the project is progressing.

Work Breakdown Structure (WBS) - A deliverable-oriented grouping of project elements, which organizes and defines the total scope of the project. Each descending level represents an increasingly detailed definition of a project component.

Working Schedule – A schedule utilized for duration of a project for creation of the baseline schedule and updates.

Work Package - A deliverable at the lowest level of the work breakdown structure. A work package contains activities.

2.0 Scheduling Software

The New Jersey Department of Transportation, Capital Program Management has adopted the use of Primavera software in XER format as the standard format for progress schedules. This software and format will be updated as newer versions become available. At Final Design, the Designer will develop a construction schedule for the proposed project. See Appendix A for an example of a Primavera Schedule view.

The Contractor will submit a preliminary and baseline construction schedule and submit bi-monthly schedule updates. All construction schedules will conform to the requirements of this manual.

3.0 Standard Practices

In developing a schedule, three basic items make CPM scheduling work: Clearly defined activities Realistic duration’s Good logic

Other good practices include:

Negative lags will not be permitted. Do not use a Finish to Start relationship with a lag. An activity must be added to represent the lag time. A project has one beginning and one end. All activities have a predecessor and successor except the project’s start and finish milestones. No "Open Ends" will be permitted. Durations of work activities do not exceed the update cycle. The Department requires the update cycle to be prepared bi-monthly. "Suspension of Dates" will not be permitted. An activity must be added. If an activity has a Start-to-Start relationship - it is to be closed with a Finish-to-Finish or Finish-to-Start relationship. (No open ends) The completion date of the CPM schedule is the completion date in Subsection 108. of the project's Special Provisions, which is be input as a Finish Milestone with a Late Finish Constraint. All intermediate milestones (Interim Completion Dates) required in the Contract are to be shown in proper logical sequence and input as either the “Start- no-Earlier-Than” or “Finish-no-Later-Than” date. Mandatory Finish and Mandatory Starts are not to be used. When updating, all "Out of Sequence" activities are to be corrected to reflect the current construction operations. Original durations will not be changed from the approved Baseline Schedule.

4.0 Standard Coding

As a means of monitoring progress schedules, the Department has developed with the Consultant and Construction industries common coding structure and procedures to be utilized from design through construction. The Designer and Contractor is required to utilize the Primavera template project containing the latest standard coding provided from the Department’s web site. Details regarding template usage are provided in Appendix C.
