1. Mobilization and preparatory work;

2. Erosion and sediment controls;

3. Clearing and grubbing;

4. Dewatering, cofferdams and reservoir control;

5. Stripping and stockpiling topsoil and salvaging existing riprap;

1.3 PROGRESS OF THE WORK

A. If Contractor fails to complete activity by its latest scheduled completion date and this failure may extend Contract Times (and/or Milestones), Contractor shall, within 7 days of such failure, submit a written statement as to how Contractor intends to correct nonperformance and return to the acceptable current progress schedule. Actions by Contractor to complete Work within Contract Times (or Milestones) will not be justification for adjustment to Contract Price or Contract Times.

B. Engineer may request a schedule recovery or mitigation plan if Contractor fails to:

(i) complete a critical scheduled activity by its latest Milestone completion date, or

(ii) satisfactorily execute Work as necessary to prevent delay to the overall completion of the Work.

C. Owner may require Contractor, at Contractor's expense, to add to its plant, equipment, or construction forces, as well as increase the working hours, if operations fall behind schedule.

1.4 PRELIMINARY PROGRESS SCHEDULE

A. As a minimum, submit two CPM schedules as follows:

1. The Bar schedule shall be sufficiently detailed to indicate such activities as shop drawing submittal and review, equipment manufacture and delivery, installation of equipment, earthwork, demolition activities, concrete placements, and subcontractor’s items of work. Construction activities of less than 1 day's duration or more than 5 days' duration shall be kept to a minimum. Each activity on the diagram shall be labeled with the following information: description, duration, start date, and finish date.

Work item durations for any activity shall not exceed thirty (30) working days. Each

01320-3 major component and subdivision component shall be accurately plotted on time scale sheets 11 inches by 17 inches or 24 inches by 36 inches in size. Not more than four sheets shall be employed to represent this overview information.

1.5 PROGRESS SCHEDULE

A. General:

1. Schedule(s) shall reflect Work logic sequences, restraints, delivery windows, review times, Contract Times, and Milestones set forth in the Agreement, and shall begin with the date of Notice to Proceed and conclude with the date of Final Completion.

2. The schedule requirement herein is the minimum required. Contractor may prepare a more sophisticated schedule if such will aid Contractor in execution and timely completion of Work.

4. Adjust or confirm schedules in accordance with this Section and the General Conditions on a monthly basis.

5. The update of the Project Schedule shall be an integral part of the estimate upon which progress payments will be made. If, in the judgment of the Owner, the Contractor fails or refuses to provide information required to accomplish a complete Project Schedule Update or revision as specified hereafter, the Contractor shall be deemed to have not provided the required estimate upon which progress payments may be made, and shall not be entitled to progress payments until it has furnished the information necessary for a complete schedule update to the satisfaction of the Owner.

6. Float time is a Project resource available to both parties to meet contract Milestones and Contract Times.

7. Use of float suppression techniques such as preferential sequencing or logic, special lead/lag logic restraints, and extended activity times are prohibited, and use of float time disclosed or implied by use of alternate float-suppression techniques shall be shared to proportionate benefit of Owner and Contractor.

8. Pursuant to above float-sharing requirement, no time extensions will be granted nor delay damages paid until a delay occurs which (i) impacts Project's critical path, (ii) consumes available float or contingency time, and (iii) extends Work beyond contract completion date.

a. Identification and listing in chronological order of those activities reasonably required to complete Work, including, but not limited to, subcontract work, fabrication, and delivery dates including required lead

01320-4 times, move-in and other preliminary activities, Project closeout and cleanup, and specified Work sequences, constraints, and Milestones, including Substantial Completion date(s). Listings to be identified by Specification section number.

1.7 CLAIMS FOR ADJUSTMENT OF CONTRACT TIMES

A. Reference the General Conditions.

B. Where Engineer and Owner has not yet rendered formal decision on Contractor claim for adjustment of Contract Times, and parties are unable to agree as to amount of adjustment to be reflected in progress schedule, Contractor shall reflect that amount of time adjustment in progress schedule as Engineer and Owner may accept as appropriate for the interim. It is understood and agreed that such interim acceptance by Engineer and Owner will not be binding and will be made only for purpose of continuing to schedule Work, until such time as formal decision as to an adjustment, if any, of the Contract Times acceptable to the Engineer and Owner has been rendered.
