4. Critical Path - The Project critical path is defined as the longest, continuous path of interrelated activities depicting project work from Notice To Proceed (NTP) to project completion. All reports and graphics indicating the Critical Path shall depict the longest path of interrelated activities. Unless otherwise approved by GSA, the Baseline Schedule Critical Path shall use all allotted Contract time. The contractor has the right to develop a schedule that forecasts an early finish. However, all time between the forecasted early finish of substantial completion and the contractual substantial completion date shall be shown as float and shall be available to the Project team.

5. Critical Path Method (CPM) - A scheduling technique using activities, durations, and interrelationships/dependencies (logic), such that all activities are interrelated with logic ties from the beginning of the project to the completion of the project. There shall be no open ended relationships in the schedule. All activities shall have at least one successor with a finish relationship (“finish to start” or “finish to finish”) except the last activity in the network.

6. Data Date - The date to which progress is updated. In most scheduling software, the data date represents the next day of work and all progress is updated through the day prior to the data date.

7. Float – is the difference between the forecasted early dates and the forecasted late dates; the amount of time an activity can be delayed without delaying the Substantial Completion Date.

Float is considered a project commodity jointly shared between GSA and the Contractor and shall be used in the best interest of completing the Project on time. The critical path is not dependent on float. Float is calculated after the critical (longest) path has been determined.

8. Float Suppression – the masking of available float through the use of constraints, unreasonable logical relationships or unreasonable durations. Float suppression techniques are not allowed. On an exception basis, the use of a zero free float constraint to depict “just in time” deliveries on projects with little or no storage might be acceptable.

9. Fragnet - A subset group of interrelated activities representing only a portion of the CPM schedule.

10. Network Plan - The Network Plan is the entire database of activities, logic, durations, and all items relating to any activity input into the scheduling software and is the complete representation of the Project Schedule prepared using the Critical Path Method and graphically shown in a time-scaled form. The network shows the sequence and interdependence of the activities, and planned and actual progress by activity, required for complete performance of the Work.

11. Project Schedule - The Project Schedule includes the Preliminary Schedule (submitted at bid or as determined by the CO), the approved Baseline Schedule (developed based on the Preliminary Schedule), and all subsequent Schedule Updates, Schedule Revisions, Recovery Schedules, and As-Built Schedule.

12. Recovery Schedule – A schedule depicting the Contractor's plan for recovery of time lost on the project.

13. Schedule Revision - A schedule in which the plan for the work is revised. A Schedule Revision is required when the current schedule no longer represents the actual or planned prosecution of the Work.

14. Schedule Update - A schedule in which only actual start dates, actual finish dates and duration percent complete is updated from the prior data date to the current data date. No revisions will be permitted in a Schedule Update (i.e. added activities, deleted activities, logical relationships, etc.).

15. Time Impact Analysis - A technique to demonstrate the effect of a schedule revision or proposed revision against the current approved Project Schedule.

16. Total Float - The amount of time an activity (or chain of activities) can be delayed without affecting the Project Substantial Completion Date.

17. Working Day - A Working Day is a calendar day scheduled for active prosecution of the work.

1.04 CRITICAL PATH METHOD SCHEDULE

A. Provide a detailed, time-scaled computer generated Project Schedule with activities representing each portion of the Work for the entire Contract Performance Period. The Project Schedule shall use the Critical Path Method (CPM) for the planning, scheduling and reporting of the work to be performed under the contract.

B. No unspecified constraints, float suppression techniques, or use of activity durations, logic ties and/or sequences deemed unreasonable by GSA shall be used in the Project Schedule.

C. As defined by the Contract, the entire project performance period shall establish the Project

Substantial Completion Date which shall be used in the planning and presentation of the Contractor’s Project Schedule. GSA reserves the right not to approve any schedule deemed to have an unrealistic forecasted Substantial Completion Date. Government approval of an early completion Project Schedule shall not modify the Contractual Substantial Completion Date or Project Completion Date. The time difference between the Contractor’s planned Substantial Completion Date and the Contract directed Substantial Completion Date shall be considered Project Float, jointly owned and for the mutual use of both the Contractor and GSA.

D. The Contractor shall provide the computer processing of the CPM schedule, graphics, required under this Section or as requested by GSA in electronic format to GSA throughout the entire project performance period until Project completion is achieved.

1.05 SUBMITTALS and MEETINGS

A. Project Schedule Requirements Meeting:

1. The Contractor shall meet with GSA within 7 calendar days after Notice to Proceed to conduct a joint review of the Project Schedule requirements in this Section.

B. Preliminary Schedule:

1. Within 14 calendar days of Notice to Proceed, Contractor shall submit a Preliminary

Schedule detailing the complete scope of work and proposed logical relationships. All Government furnished equipment and materials shall be identified with dates needed to be received by the Contractor.

2. Within 7 calendar days of receipt by the GSA of the Preliminary Schedule, the Contractor and GSA shall meet to discuss the results of GSA's schedule review. To the extent that revisions are required, the Contractor shall resubmit the Preliminary Schedule to the GSA for approval within [seven (7) calendars days of receipt of the GSA's comments.

C. Baseline Project Schedule

1. Schedule activities shall be cost loaded in whole dollars and the assigned dollar value (cost-loading) of each activity of the Network shall cumulatively equal the specified Bid Item Breakdown and Total Contract Amount

2. For any items that the Contractor intends to bill for stored materials (when allowed by contract), these items need to be shown as separate “material procurement” activities in the

CRITICAL PATH METHOD SCHEDULING – SHORT DURATION SMALL PROJECTS 013120 - 4

schedule and the material dollars only placed on these activities. Billing for stored materials on any other schedule activities not broken out in this manner will not be allowed.

3. Include an activity code field “SOV” for the coding of each schedule activity with the schedule of value (SOV) line items; this is for the tabulation and summarization of contractor assigned cost-loading Schedule of Values for application of Progress Payment Request reporting.

D. Submit the Baseline Project Schedule within 7 calendar days after approval of the Preliminary

Schedule. The Baseline Schedule shall be the Contractor's detailed plan for ALL work from NTP through contract completion. All punch list work shall be completed to, or prior to, the Contract Completion Date.

E. Unless otherwise approved by the GSA, the Project Schedule shall include, but is not limited to, the following items:

a. Activities necessary to depict time to prepare submittals, time for the GSA to review submittals, procurement, design, construction, third party inspections, close-out, start-up, testing and balancing, commissioning and turnover, and work by separate contractors.

b. The schedule shall include separate activities for the submittal, review, procurement or fabrication, and delivery of key and long-lead items. The Project Schedule shall indicate submittal dates, and depict the review period as defined in the Contract or Supplementary Provisions for A/E/GSA review. Procurement/submittal activities shall be assigned codes that will allow these activities to be sorted and printed separately from the construction/close-out/commissioning work activities.

c. The Baseline Schedule shall have a Data Date no later than NTP, and no activities shall be progressed to show work completed to date without prior acceptance of the GSA.

d. Activity descriptions of the work shall include area designators sufficient to identify where the Work will occur, and shall match the Key Plans. The work related to each Activity shall be limited to one work trade and one area.

e. Interrelationships (logic) and sequencing for ALL activities. Each activity shall have at least one successor (except for the last activity) relationship to form a logically connected Network Plan from NTP to the Contract Completion Date. Each activity shall have at least one successor with a finish relationship (finish-to-start or finish-to-finish relationship).

f. Activity durations shall be in units of whole work days. Except submittal and procurement activities, durations shall not exceed one reporting period [Team define i.e. month)]____ (User Defined #6) unless approved by the GSA. Durations for Government submittal reviews shall meet the requirements set forth in the Contract Documents. Activity durations shall not be overly short. One day durations shall not be assigned unless specifically requested by the contractor and specifically accepted by the GSA. Activity durations are expected to be between one week and one month, however shorter or longer durations can be assigned as needed to properly plan and coordinate the work.

g. Contractual milestone events as defined in the Contract Documents including, but not limited to, phased work, work restrictions/access/shift work, and work being performed by separate contractors shall be included in the schedule. The substantial completion and project completion tasks shall be assigned to a seven (7) day work week calendar.

h. ALL activities shall at a minimum be coded by Area, Responsibility (trade/ subcontractor), and Phase . Additional codes are allowed to sufficiently identify where work will occur.

Codes shall be a maximum of six (6) characters and abbreviations shall be fully described in the Project Schedule narrative. The Contractor’s self-performed work shall be clearly identifiable.

F. Baseline Schedule Review Process and Submittal Requirements

CRITICAL PATH METHOD SCHEDULING – SHORT DURATION SMALL PROJECTS 013120 - 5

1. The GSA will review the Baseline Schedule and provide comments to the Contractor within 7 calendar days of receipt of submittal and, if needed, will arrange for a Baseline Schedule Review Meeting with the Contractor for discussion of the schedule. The Baseline Schedule, when approved, shall become the basis for the next monthly Schedule Update submitted by the Contractor.

a. Baseline Schedule Review Meeting. The Contractor shall present the Baseline Schedule to GSA at the review meeting, and describe the Contractor's means and methods for accomplishing the Work [include if required earlier: and the cost loading of the schedule.]

b. In the event that GSA provides comments or the Baseline Schedule does NOT meet the requirements of this specification, the contractor shall, within [seven (7)] calendar days, revise the Project Schedule to bring it into compliance with these requirements, and Contractor shall make a full Baseline Schedule submission for GSA’s review and approval.

c. Upon approval of the Baseline Schedule by the GSA, the cost-loaded values shown in the

Project Schedule and progress of activities will be used as a basis for determining progress payments. Monthly progress payments shall be based upon information developed using the current monthly Schedule Update. The computer generated cost report will be used by the GSA for verification of the Application for Payment submitted by the Contractor.

d. GSA's approval of the Baseline Project Schedule does not relieve the Contractor of responsibility whatsoever for the accuracy or feasibility of the Project Schedule, or of the Contractor’s ability to meet the Substantial Completion Date. Such acceptance does not create a warranty, expressed or implied, or acknowledge or admit the reasonableness of the activities, logic, durations, manpower, cost or equipment loading of the Contractor’s Project Schedule.

e. If the Contractor fails to timely submit the Baseline Schedule, the GSA may withhold approval of progress payments until the Contractor submits the required Project Schedule.

2. The Baseline Schedule submission shall be comprised of the following, unless otherwise requested by the GSA:

a. One (1) electronic copy of the entire Project Schedule shall be uploaded into ePM and provided in native electronic format and a PDF. The electronic copy shall be in a compressed format. The electronic filename shall have a unique identifier. Hard copy prints and reports shall be generated from the same version of the Project Schedule that is provided in electronic form.

b. Two (2) full-color prints of the Network Plan (in time-scaled form), unless otherwise designated by the Contacting Officer. Prints shall be standard size sheets. The following information shall be shown on the prints: Activity ID, Activity Description, Calendar ID, Original Duration, Remaining Duration, Percent Complete, Area Code, Responsibility Code, Early Start, Early Finish, Total Float, Budgeted Cost, and Budgeted Quantity (i.e., labor, materials, equipment, etc.). The prints shall include legends, dates and titles to sufficiently identify the Project Schedule A narrative providing additional clarification/explanation of items such that GSA is informed of the approach used to plan and sequence the work, coordinate with other separate contractors to the extent

CRITICAL PATH METHOD SCHEDULING – SHORT DURATION SMALL PROJECTS 013120 - 6

applicable, and resource and cost load the Project Schedule.

G. Schedule Updates
