B. On a date determined by the ENGINEER, the CONTRACTOR shall meet with the ENGINEER to review the CONTRACTOR’s Progress Payment Application and its required supporting documents, including its Narrative Progress Report and its Construction Schedule Update.

1. Appendix E of this Specification section outlines the update preparation and review sequence to be used for preparation, submittal and review of the Narrative Progress Report and Construction Schedule update.

2. The CONTRACTOR and the ENGINEER will review the Draft submittal, discuss its content and the ENGINEER will authorize modifications, as appropriate, to facilitate approval of the Payment Application.

3. Following the review meeting, only those revisions authorization by the ENGINEER shall be incorporated into the electronic file entitled “Update” which shall then be submitted as the record schedule for the progress period update.

4. The ENGINEER shall be allowed seven days after the meeting to review and determine the acceptability of the Narrative Progress Report and Construction Schedule update. This variance from the typical submittal review period is made specifically to facilitate timely processing of the CONTRACTOR’s Progress Payment Application.

5. Narrative Progress Report and Construction Schedule updates returned to the CONTRACTOR marked “Revise & Resubmit” or “Not Acceptable” shall constitute a deficient payment application that will not be processed for payment until the schedule report is acceptable to the ENGINEER.

6. Narrative Progress Report and Construction Schedule updates returned to the CONTRACTOR marked “Revise & Resubmit” or “Not Acceptable” shall be resubmitted to the ENGINEER within seven days, at which time a new seven day review period will begin for the ENGINEER.

C. The Narrative Progress Report shall summarize the schedule status and be organized as follows:

1. The CONTRACTOR's transmittal letter, containing the submittal number.

2. Contents Sheet

3. Identification of the Update including the Data Date, Update Period and the

Schedule File Names as defined in Appendix D to this Specification section.

4. Update Summary including the variance between Contract Milestone dates and their predicted completion dates; Contract Completion variance for the reporting period; the number of days ahead or behind schedule; weather days taken and remaining from the Contract allowance and tables summarizing the status of Contract finances and time. At a minimum the CONTRACTOR shall provide the data required by the example in Appendix G of this Specification section.

5. Analysis of Critical Path and each negative Float Path describing the nature of the Critical Path, its impact and the impact of any negative float path on other activities, milestones and completion dates:

6. All current and anticipated time impacts describing the origin of each event; corrective action and schedule adjustments to correct it; recommendations to recover from it and the effect that it may have on other activities, milestones and completion dates.

7. Pending status of outstanding issues such as permits, if any; Contract modifications, RFC’s and or RFP’s containing requests for time adjustment; long-lead procurement items; safety reports and any code violations or warnings.

8. Narrative discussion of contract status including highlights of work by area, progress, completion, impediments, changes to the Work plan, issues and concerns accompanied by OCSD Activities and Schedule Change Tables. At a minimum the CONTRACTOR shall provide the data required in Appendix G of this Specification section.

D. Progress Period Schedule Updates:

1. The CONTRACTOR shall be responsible for preparing and submitting updated schedules, related reports and diagrams, as part of its periodic update Report.

2. The Construction Schedule update shall measure and record only those facts that have occurred to the Work including physical percent complete type, actual start and finish dates, and duration changes. Modifications to logic, durations of activities not started or to actual dates already recorded in previous updates shall not be allowed unless authorized in writing by the ENGINEER. An electronic file shall be created and entitled “Pure Progress” and included with the update.

3. With each update the CONTRACTOR shall identify any changes to the schedule, such as Field Change Orders, accepted time adjustment requests, new activities, constraint changes, deleted activities, activity duration changes, activity description changes, and changes in logic relationships between activities in a Schedule Change Table as detailed in Appendix G of this Specification section. Logic changes shall be described with an explanation of the rationale for the change provided in the report. Such revisions may be incorporated into an electronic file entitled “Draft Update” for target comparison with the “Pure Progress” update. The CONTRACTOR shall provide printed diagrams of the target comparisons as part of its presentation to the review meeting.

4. All progress period schedule updates shall be compared to the Baseline Construction Schedule. In addition, each current progress period update shall be compared to the previous period update. Each update shall be labeled with the OCSD project number, data date and title abbreviation identified on the hard copy and electronic file as described in Appendix G of this Specification section.

5. The schedule shall be updated with actual start and finish dates for every in- progress or completed activity, as documented by the CONTRACTOR’s Daily Reports and Three Week Look Ahead schedules. No other basis, including automated software calculations or default mechanisms shall be allowed. Failure of the CONTRACTOR to ensure that documented dates as specified herein are incorporated into the schedule update shall constitute cause for disapproval of the update and the inability of the ENGINEER to accurately evaluate the CONTRACTOR’s progress for payment purposes.

6. Activities that have reported progress without predecessor activities being completed such as Finish to Start (FS) Relationships with out of sequence progress will not be allowed except on a case-by-case basis with the written acceptance by the ENGINEER. A written explanation of each such activity shall be included with each update in the Schedule Change Table as detailed in Appendix G of this Specification section. The ENGINEER may direct that changes in schedule logic be made to correct any or all out-of-sequence Work.

7. Change order work shall be identified in the schedule as a new activity inserted into the affected schedule logic. The schedule activity shall only be added after the Change Order is approved for payment by OCSD.

1.13 CONSTRUCTION SCHEDULE REVISION

A. If the CONTRACTOR decides to make major changes to the sequencing and logic of the accepted work plan it shall prepare a schedule reflecting its proposed changes for submittal to, and review by, the ENGINEER separate and apart from the periodic schedule updates.

B. The CONTRACTOR’s submittal shall be made in accordance with the requirements of the Contract Documents and the ENGINEER will have a maximum 25 day period for review before scheduling a meeting with the CONTRACTOR.

C. A Revised Schedule that results in a predicted completion date later than the Contract Completion date shall be rejected unless the delay is deemed to be excusable or caused by OCSD and a time extension is authorized in writing by the ENGINEER.

D. The ENGINEER will then arrange a meeting with the CONTRACTOR to review the submittal, discuss its content, and authorize modifications required to allow its integration into the Construction Schedule.

1.14 AS-BUILT CONSTRUCTION SCHEDULE

A. As a condition precedent to release of any retention, the CONTRACTOR shall submit its As-Built Construction Schedule. The As-Built Construction Schedule shall reflect the manner in which the contract was actually constructed including start and completion dates, and all activities, sequences, and logic ties.

B. This schedule submission shall be accompanied by a certification, signed by an officer of the CONTRACTOR’s company, the CONTRACTOR’s Project Manager and Construction Scheduler, stating “To the best of our knowledge, the accompanying As- Built Construction Schedule accurately reflects the actual start and completion dates and logical relationships of all activities contained herein and represents an accurate depiction of the way in which the contract was constructed.”

1.15 WEEKLY THREE WEEK LOOK AHEAD

A. The CONTRACTOR shall submit an electronic copy of the Three Week Look Ahead schedule to the ENGINEER no later than 48 hours prior to the weekly construction progress meeting. The Three Week Look Ahead schedule shall be developed maintained and provided using MS Excel^® software, shall be in the form shown in Appendix G and

include at a minimum actual performance for the previous week compared to the planned work for the previous week, planned work for the current week and planned work for the two weeks following the current week.

C. The CONTRACTOR shall use the Three Week Look Ahead schedule actual performance record in preparing its Construction Schedule update.

1.16 FLOAT OWNERSHIP AND EARLY COMPLETION

A. Total float, free float, independent float, near-critical float, critical path float, slack time, or contingency within the overall Construction Schedule is not for the exclusive use of either OCSD or the CONTRACTOR but is jointly owned by both and is an expiring resource available to and shared by both as needed to meet Contract Milestones and the Contract Completion date.

B. Pursuant to the float sharing requirements of the Contract, use of float suppression techniques such as preferential sequencing, special lead/lag logic restraints, extended activity times, or imposed dates shall be cause for rejection of the Construction Schedule and any revisions or updates thereto.

C. Within fifteen days of Contract award, the CONTRACTOR shall formally notify OCSD in writing of its intent to finish the Work earlier than the Contract Completion date. Agreement between the ENGINEER and the CONTRACTOR to adopt an early completion Baseline Construction Schedule shall include agreement by both parties to amend the Contract Milestones, completion dates, and associated liquidated damages, by Change Order, to those completion dates contained in the agreed to schedule.

1.17 TIME ADJUSTMENT REQUESTS

A. Requests for time adjustments shall be submitted in the time and manner specified in the Contract Documents, as described herein and further elaborated in Appendix F of this Specification section.

B. OCSD initiated changes that extend or shorten the Contract Duration shall be the sole basis to adjust the Contract Completion date. Delays in the critical path not associated with proper requests for time extensions in accordance with the Contract Documents shall be deemed to be the responsibility of the CONTRACTOR.

1.18 REMEDIAL MEASURES AND RECOVERY SCHEDULE

A. The CONTRACTOR shall mitigate any potential delay to the Work as efficiently and economically as possible regardless of cause. Where practical the CONTRACTOR shall do so without added cost or adverse time impact. Prior to initiating any action for which it expects OCSD to be liable, the CONTRACTOR shall notify the ENGINEER in writing and receive written authorization to proceed.

B. If the CONTRACTOR believes the delay may result in a predicted completion date later than the Contract Completion date, it shall review all uncompleted activities on the critical and near critical paths to assess mitigation options and, within seven days of discovering the potential delay it shall submit a written statement to the ENGINEER describing its plan to recover, including a statement that it has verified the accuracy of all critical and near critical paths. Following acceptance by the ENGINEER the CONTRACTOR shall incorporate its recovery plan into the next schedule update.

C. Whenever it becomes apparent to the ENGINEER that the current schedule update shows a delay to the critical path, that these delays are through no fault of OCSD and hence, the Contract completion date will not be met, or when so directed by the ENGINEER, the CONTRACTOR shall submit to the ENGINEER for review a written statement of the steps it intends to take to remove or arrest the delay to the schedule and the CONTRACTOR shall promptly provide the requisite level of effort to bring the Work back on schedule. The CONTRACTOR shall then incorporate its recovery plan into the next Construction Schedule update.

D. A Recovery Schedule that results in a predicted completion date later than the Contract Completion date shall be rejected unless the ENGINEER determines that the delay is the responsibility of OCSD, is excusable or that it cannot be mitigated, and authorizes a time extension in writing.

E. The ENGINEER may require the CONTRACTOR to provide reasonable additional resources to recover from any schedule delay, however under no circumstances will the addition of equipment or construction forces, increasing the working hours or any other method, manner, or procedure to recover from delays to the Schedule be considered justification for contract modification for extra Work.
