689CONSTRUCTION SCHEDULING

689.1DESCRIPTION—This work is the preparation, maintenance, and revision of the construction project

schedule using a Narrative, Critical Path Method (CPM), or Resource Loaded CPM Schedule, as indicated, to monitor progress of project operations. For Design/Build or Partial Design/Build projects, include in the construction schedule design activities associated with the Design/Build elements of the project as well as the review and approval durations as indicated in the contract provisions. Definitions are as follows:

• Controlling Activities. Those activities that control the total length of the project time by forming a chain that makes up the largest sum of activity durations. In the CPM Schedule these activities are also identified as Critical Path Activities.

• Float. The length of time that the start or finish of an activity can be delayed without affecting the Required Completion Date of the project. Float is a shared commodity.

• Redundant Relationship. A relationship representing a link between activities that is also represented in a parallel path or relationship. Redundant relationships can be removed without impacting the logic or calculations of the schedule and may add unnecessary complexity to the schedule and hinder review and analysis.

• Resource. The labor and equipment required by an activity and needed to perform the work of the project.

689.2MATERIAL—The Department's software standard for scheduling and project management is Asta

Powerproject produced by Elecosoft. The Contractor may use a commercial scheduling software package to produce the schedule and reports according to the requirements of this specification. The Contractor may elect to submit the Narrative Schedule or related reports to the Representative in electronic format. In all cases, the CPM Schedule must be developed in Asta Powerproject (.pp) or a compatible format (.mpp, .xml, .xer, .p3b, .dir, and .stx). Verify the compatibility of the other software packages with the Department’s version of Asta Powerproject. The CPM Schedule must be submitted to the Representative in an Asta Powerproject (.pp) electronic format. If the CPM Schedule is developed in an Asta Powerproject compatible format, convert the native CPM Schedule format to an Asta Powerproject (.pp) file format using the PennDOT Construction template before submitting to the Representative. Ensure the converted file is a one to one comparison between the native format and the Asta Powerproject file before submittal. Upload and submit the Asta Powerproject (.pp) schedule through the PennDOT Project Collaboration Center (PPCC). Uploading the schedule into PPCC will allow all authorized parties to view the current baseline schedule. The Department will then review the submitted schedule and will either accept, Accept as Noted, Revise and Resubmit, or reject the schedule. Once the schedule is accepted by the Department, the Asta Powerproject (.pp) file will be the governing schedule on record. After the schedule is accepted, the Department will download the accepted schedule from PPCC and upload it to Asta Vision. Any subsequent changes to the baseline schedule through the submission of any updates, revisions or recovery schedules will also be uploaded to the project within PPCC in the same way to maintain a record of schedule versions.

689.3CONSTRUCTION—As specified in Section 108.03(b), Construction Project Scheduling, and as follows:

in the proposal. Submit the Narrative Schedule within 15 calendar days after the actual Notice to Proceed Date. The District Executive may withhold current estimate payments until the Narrative Schedule is submitted and accepted. If the actual Notice to Proceed is issued after the anticipated Notice to Proceed Date in the proposal, submit a Narrative Schedule based on the actual Notice to Proceed Date within 15 calendar days after the acceptance of the Narrative Schedule based on the anticipated Notice to Proceed Date . The Narrative Schedule based on the actual Notice to Proceed Date will not be considered without prior acceptance of

the Narrative Schedule based on the anticipated Notice to Proceed Date in the proposal. The Representative will review and respond to the detailed Narrative Schedule and supporting documentation within 14 calendar days of receipt. Include, as a minimum, the following in the initial Narrative Schedule and in all Schedule revisions:

• Activity description;

• Activity duration, in working days; and

• Start and finish calendar dates of activities.

In addition, submit a workday calendar showing work days and non-work days, number of shifts per day, and number of hours per shift. Provide enough activities to demonstrate t he necessary interdependencies. Use the above information to complete a narrative description of the construction schedule. If the Narrative Schedule is not received within 15 calendar days after the actual Notice to Proceed Date, the Contractor will be required to attend a scheduling workshop to prepare an acceptable Narrative Schedule. The District Executive may elect not to release current estimate payments until the Narrative Schedule is submitted and accepted.

Day Work Plan from Asta Powerproject that includes a breakdown of activities. Provide a generalized project schedule for the balance of the work, to meet the Required Completion Date and specified Milestone Date(s). Instead of the 60 Calendar Day Work Plan, the Contractor may submit the CPM Schedule specified in Section 689.3(b)3 within 30 calendar days after the contract execution. Maintain and submit, on a bi-weekly basis, a 60 Calendar Day Work Plan until the CPM Schedule is accepted.

days after contract execution. At a minimum, this schedule should include the scheduling concepts and logic that were used in sequencing work activities to prepare the contract bid, a workday calendar that identifies work days and non-work days, the number of shifts per day, and the number of hours per shift. Instead of the Bid Preparation Schedule, the Contractor may submit the CPM Schedule specified in Section 689.3(b)3 within 30 calendar days after the Notice to Proceed . The District Executive, after consultation with the Contractor, may withhold current estimate payments until the Bid Preparation Schedule or CPM Schedule is submitted and accepted.

proposal. Submit the CPM Schedule through PPCC in an Asta Powerproject (.pp) file format using the PennDOT Construction template as defined in Publication 615 within 30 calendar days after the actual Notice to Proceed Date. Also, submit the schedule as a portable document format ( PDF) through PPCC. The PDF must be generated from Asta Powerproject as an 11-inch by 17-inch page size, with no more than 25 activities per sheet. Ensure the PDF text is large enough to read. If the actual Notice to Proceed is issued after the anticipated Notice to Proceed Date in the proposal, submit a CPM Schedule based on the actual Notice to Proceed Date within 15 calendar days after acceptance of the CPM Schedule based on the anticipated Notice to Proceed Date . The CPM Schedule based on the actual Notice to Proceed Date will not be considered without prior acceptance of the CPM Schedule based on the anticipated Notice to Proceed Date in the proposal. Include, a t a minimum, the following information for each activity in the initial baseline schedule submission and all subsequent submissions:

• Activity ID

• Activity description

• Activity duration, in working days

• Early start date

• Early finish date

• Late start date

• Late finish date

• Total float

• Predecessor

• Successor

• Calendar

• Resource Allocation (if applicable)

• Resource Effort (if applicable)

The Representative(s) will review and respond to the detailed CPM Schedule within 14 calendar days of receipt. If the Department does not accept the schedule, revise the schedule and re-submit within 10 days of receiving the Department’s comments. If the CPM Schedule is not received within 30 calendar days of the actual Notice to Proceed Date, the Contractor will be required to attend a scheduling workshop to prepare an acceptable CPM Schedule. The District Executive, after consultation with the C ontractor may withhold current estimate payments until the CPM Schedule is submitted and accepted. A standardized list of activities must be utilized in all CPM and CPM Resource Loaded schedules. These activities must be used verbatim if they are applicable to the project. The description of these activities cannot be modified. The following is a list of standardized activities that must be included where applicable:

• Project Award

• Notice to Proceed (Anticipated, unless issued after the Anticipated then use Actual)

• Physical Work Start

• Implement Detour

• Remove Detour

• Open to Traffic

• Physical Work Complete

• Project Completion

Use a unique activity ID to describe each activity throughout the duration of the project. Limit activities with duration times in excess o f 15 working days to a minimum. Provide enough activities to demonstrate the necessary interdependencies. Limit the fineness of detail, where possible, to a minimum, 5-day activity

duration. All activities, except the single start activity and the single finish activity must have at least one predecessor and one successor The number of redundant relationships is not to exceed 5% of the total number of relationships in the schedule. Submit the CPM Schedule with the following format:

• Make all relationships finish to start relationships.

• Identify a single start activity and a single finish activity for the entire schedule.

• Imposed start date set to anticipated Notice to Proceed (or actual if applicable.)

• Incorporate lag/lead times as a separate activity.

• Incorporate the standardized activities verbatim (if applicable to the project.)

• ‘Start on’ or ‘Start on or After’ Constraint on Notice to Proceed.

• ‘Finish on’ or ‘Finish on or Before’ Constraint on Project Completion.

• Interim Milestone included in the contract should use soft constraints (i.e. ‘Start on or After’ or ‘Finish on or Before’) and utilize a 7 day no holiday calendar.

Submit schedule updates at the frequency specified in Section 108.03(b) using the accepted baseline schedule as the basis for the update . Ensure updates are prepared in the proper format and include the content as described. Failure to submit acceptable schedule updates will impact contractor evaluations. Activity IDs or descriptions must remain constant throughout the projec t. Major changes to activities will be addressed by eliminating the existing activity and substituting a new activity with a unique ID and Description. Progress the schedule through the end of the established progress period with actual start and finish dates and remaining duration (or overall percent complete). Perform a ‘reschedule’ of the Asta Powerproject (.pp) file with the options set as follows:

• straighten the progress period to ‘Progress Entry Period’

• set progress entry period to Default (progress date agreed upon with District)

Include with updates:

•:

• Electronic schedule in Asta Powerproject (.pp) file format for review.

• A narrative report including:

ͦ The reason for the update. ͦ Progressed Activities

• Logic changes (including relationship type and imposed date(s))

• Calendar changes (including activity association and/or workday(s))

• Duration changes

• Critical Path changes

• Any schedule concerns.

• A PDF of the updated schedule showing the following information (In the PennDOT Construction Template the Construction Update view includes all of these columns):

ͦ Unique Task ID ͦ Activity description ͦ Activity duration, in working days ͦ Original Baseline Duration ͦ Early start date ͦ Early finish date ͦ Late start date ͦ Late finish date ͦ Total float ͦ Predecessor (using unique task ID) ͦ Successor (using unique task ID) ͦ Actual Start date ͦ Actual Finish date ͦ Remaining Duration (or overall percent complete) ͦ Resource Allocation and Effort (if applicable)

• Submit the narrative report, the CPM Schedule update in an Asta Powerproject (.pp) format, and PDF of progressed schedule through PPCC. The PDF must be generated from Asta Powerproject, should be a 11 inch by 17-inch page size, with no more than 25 activities per sheet. Ensure the PDF text is large enough to read.

The Department will review the updated schedule within 14 calendar days of receipt. If an updated schedule is not submitted in the format required, the District Executive, after consultation with the Contractor, may withhold current estimate payments until acceptable monthly updates as specified herein are received.
