D. Section 013200 – Construction Progress Documentation

E. Section 017700 – Close Out Procedures

1.03 DEFINITIONS

A. Definitions applicable to this Section include the following:

1. Activity - An element of the Work or task performed during the course of the project. Each schedule activity shall be a clearly defined, manageable and monitorable task depicting an estimated duration, an estimated cost, and estimated manpower requirements. Each activity shall be limited to one trade unless the GSA specifically approves otherwise on an exception basis.

2. Baseline Schedule - The original work plan approved by GSA as the Project Schedule depicting the contractor’s plan to prosecute the work.

3. Constraint - A scheduling restriction imposed on the start date, finish date or float of an activity. No constraints will be allowed. Exception: for projects with limited or no storage areas requiring “just in time” deliveries, a zero free float may be acceptable.

4. Critical Path - The Project critical path is defined as the longest, continuous path of interrelated activities depicting project work from notice of award (or 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 – The amount of time an activity can be delayed in a project network without causing delay to subsequent activities (free float) or the project completion date (total float). 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.

8. Free Float - the amount of time that an activity can be delayed without delaying a successor activity.

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

10. Float Suppression - the masking of available float through the use of constraints, unreasonable logical relationships or unreasonable durations. Float suppression techniques are not be 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. .

11. Fragnet – A subset group of interrelated activities representing only a portion of the CPM schedule.

12. Key Plans - Key Plans are graphic representations on prints of the Contract Documents of the Contractor’s planned breakdown of the project for scheduling purposes. The key plans will clearly define the boundaries of the work for each designated area. The alphanumeric codes on the key plans shall match the code values for the activity code "Area" in the Project schedule.

13. 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.

14. 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.

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

16. Retained Logic – When you choose Retained Logic, the remaining duration of a progressed activity is not scheduled until the logical relationships of all predecessors are satisfied. When you choose Progress Override, network logic is ignored and the activity can progress without delay

17. 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.

18. Schedule Update - A schedule in which only actual start dates, actual finish dates and duration percent completes are 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.)

19. Time Impact Analysis - A technique to demonstrate a revision or proposed revision against the current approved Project Schedule.

20. 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, and will be produced using the most current version of scheduling software, compatible with Meridian Proliance. The CPM scheduling software shall be capable of generating and depicting the longest path of the schedule network. For project collaboration and project reporting of the electronic CPM database with the GSA and others, over enterprise software & servers, the project elements such as resources, calendars, and activity codes, etc.

need to be defined at the “Project Level” rather than the “Global Level”.

B. No Constraints Float suppression techniques shall be used in the Project Schedule without a specific request from the contractor and a specific approval from the GSA. CPM calculations to be based on retained logic software setting. No out-of-sequence progress is allowed in schedule revisions. Out of sequence progressed activities shall be corrected with the proper logic and progress override will not be allowed.

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. If the Contractor forecasts a planned early Substantial Completion Date in the Baseline Project Schedule, Approval of a planned early completion date is solely at the discretion of GSA. 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 Contract directed 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. All indirect costs (home office general conditions, field general conditions, etc. shall be included through the final Contract Completion date.

D. The Contractor shall provide the computer processing of the CPM schedule, graphics, cost and resource reports required under this Section and/or as requested by the GSA at no additional cost to GSA throughout the entire project performance period until Project completion is achieved.

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.

c. 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.

c. The time impact analysis (TIA) shall be performed on the current schedule of record at the time the impact or delay occurred. Because many schedule updates include forecasted recovery efforts, prior to performing the TIA, a status analysis shall be performed to determine schedule delays to date at the time of the impact. The status analysis shall compare the progress of work in the current schedule (or time of the impact if required by the GSA) against the approved baseline schedule or (subsequent approved, revised baseline schedule).

d. Schedule delays determined by the status analysis shall be quantified and assigned to the responsible party prior to incorporation of the time impact analysis into the current schedule of record. (For instance, if comparison of the current monthly update to the approved baseline schedule results in showing the project is behind schedule by one month, that one month of delay shall be inserted back into the current schedule as a fragnet prior to insertion of the fragnet representing the current impact or delay.)

e. Contractor shall submit its proposed schedule revisions in Fragnet form. Fragnets shall be accompanied by a detailed narrative explaining the reason for the revision, the anticipated effect of the revision on the Project Schedule and Substantial Completion Date, including describing the change in the affected activities’ Total Float value.

7. On Projects in which many fragnets are submitted in support of impacts to the Project, the

GSA may require periodic (weekly or monthly) Fragnet Meetings. Either party can propose fragnets in the fragnet meeting. In the Fragnet Meeting, each fragnet shall be accompanied with a spreadsheet depicting the following:

a. unique Fragnet Number,

b. date of the Fragnet,

c. schedule for the Fragnet to be inserted into,

d. data date of the schedule the fragnet is to be inserted into,

e. the predecessor activity ID and activity name the fragnet is proposed to be linked to,

f. The successor activity ID and activity name the fragnet is proposed to be linked to,

g. total float for the path prior to insertion of the fragnet,

h. anticipated total float after the fragnet is inserted.

i. Anticipated impact to the forecasted substantial completion date.

j. Failure of the Contractor to timely submit a Time Impact Analysis within the time stated in Paragraph 1.05.F.4.e below, shall mean that it is mutually agreed that the particular modification, delay, or Contractor request does not require an extension of the contract time.

k. Approval or rejection of each Time Impact Analysis by the GSA shall be made within one week after receipt of each Time Impact Analysis, unless subsequent meetings and negotiations are necessary. Upon approval, a copy of the Time Impact Analysis signed by the GSA shall be returned to the Contractor and incorporated into the Project Schedule at the next Schedule Revision which will be become the current approved Project Schedule.

l. The Contractor shall submit a Time Impact Analysis as follows:

i. Within five (5) work days after receipt of a written change modification.

ii. Within five (5) work days after receipt of a written notice by the GSA.

iii. Within five (5) work days from the beginning of a delay caused by unforeseeable circumstances.

m. The Time Impact Analysis shall meet the requirements for submittal of a Schedule

Revision including a Fragnet (see Section 1.05.F.3.c) with sufficient supporting documentation to enable the GSA to make a determination on the Contractor’s request for time extension.

G. As-Built Schedule

1. Along with the final pay application, the Contractor shall submit an As-Built Schedule documenting actual start and actual finish dates for all activities, and logic ties between all activities to show the actual sequence in which the work was performed.

1.06 RESPONSIBILITY FOR COMPLETION

A. If, in the opinion of the GSA, the Contractor falls behind the planned progress as noted by negative float shown on the current monthly Schedule Update, the Contractor shall take any and all steps necessary to improve its progress at no additional cost to the Government. This shall not be construed as prohibiting the Contractor from increasing the number of working hours, shifts per day, working days per week, or the amount of construction equipment, or any combination of the foregoing, to eliminate the delay in the scheduled progress.

B. Failure of the Contractor to comply with the requirements of the GSA under Paragraph 1.06.A shall be grounds for determination by the GSA that the Contractor is not prosecuting the work with such diligence as will ensure completion within the contract time. Upon such determination, the GSA may terminate the Contractor's right to proceed with the work, or any separable part thereof, in accordance with the applicable provisions of the contract.

1.07 PAYMENTS TO CONTRACTOR

A. The GSA shall review the Contractor's monthly request for payment upon receipt and shall process the request for payment based upon the current approved Schedule Update. The GSA will consider the Contractor's overall progress toward Project Completion along with the progress for discrete activities to determine the amount to be approved for the monthly payment request.

1.08 PERFORMANCE MONITORING

A. The GSA may elect throughout, or at any time during the Project, to record the number of workers and construction equipment working on each construction schedule activity in each area of the Project. The GSA's request for this information will be without additional cost to the Government and shall be provided within one week of receipt of the GSA's written request. This information will be used by the GSA to evaluate the adequacy of the Contractor’s performance and project manpower staffing, as well as any Contractor claims.

B. The Contractor is required to attend construction coordination meetings. As such, the Contractor shall present a printout of the current approved schedule depicting only the work planned for the month The bar chart should be sorted by Area by Total Float or as requested by the GSA.

Information to be shown on the bar chart includes: Activity ID, calendar, Activity Description, Original Duration, Remaining Duration, Percent Complete, Early Start/Actual Start, Early Finish, and Total Float.

1.09 SCHEDULER REQUIREMENTS/QUALIFICATIONS

A. Within five (5) work days after the date of Notice to Proceed, the Contractor shall designate in writing an authorized scheduler or scheduling representative in the Contractor’s organization who shall be responsible for coordinating with the GSA during the preparation and maintenance of the Project Schedule. Contractor's scheduler shall possess demonstrated proficiency in CPM schedule methodology and use of the current version of a Project Planner software.

B. The Contractor’s scheduling representative is considered key personnel by GSA. As such, GSA shall have the right to review the qualifications of the individual assigned as the scheduling representative. The Contractor’s scheduling representative shall have complete authority to act on behalf of the Contractor in fulfilling the Project Schedule requirements of the Contract. The Contractor shall notify GSA in writing of any proposed changes in this position, and shall not change/substitute the scheduling representative without the prior written consent of the GSA.

C. The Contractor agrees that whenever GSA shall inform the Contractor in writing that the

Contractor’s scheduling representative is not performing his duties to the satisfaction of the Government, the Contractor shall change such representative at no additional cost to the Government and designate in writing, within one week of notification from the GSA, a new authorized representative satisfactory to the GSA.

D. The Contractor’s project superintendent, and the scheduling representative and, to the extent applicable, the personnel responsible for developing and inputting information into the Project Schedule shall attend schedule related meetings and monthly update meetings throughout the duration of the Project.
