Such removals, alterations, and/or relocations, where necessary, will be made by others. The locations shown on the drawings for underground utilities are approximate only. The exact locations of such utilities shall be determined by the Contractor in the field prior to commencing construction operations in their vicinity.

b. The attention of the Contractor is directed to the possibility that public utilities or private improvements may be encountered within the construction limits, some of which may be buried, and the existence of which is presently not known. Should any such utilities or improvements be encountered, the Contractor shall immediately notify the Contracting Officer so that a determination may be made as to whether they shall be removed, relocated, or altered. After such determination is made, the Contractor shall, if so directed by the Contracting Officer, remove, relocate, or alter them as required and an equitable adjustment will be made. In the event the Contracting Officer arranges for such removals, alterations, or relocations to be performed by others, the Contractor shall cooperate with such others during the latters' removal, alteration, or relocation operations.

1.3 DAMAGE TO WORK

a. The responsibility for damage to any part of the work to be performed under this contract shall be as set forth in the clause of the contract entitled "Permits and Responsibilities". However, if the cofferdam(s) is constructed in accordance with plans and progress schedules approved by the Contracting Officer, but is overtopped by flood and such flood causes damage to the cofferdam or if any part of the permanent work is damaged by flood or earthquake, which damage is not due to the failure of the Contractor to take reasonable precaution or to exercise sound engineering and construction practices in the conduct of the work, the Contractor shall make the repairs ordered by the Contracting Officer and full compensation for such repairs will be made at the applicable contract unit or lump sum prices as fixed and established in the contract.

The work tasks, milestones, and lock closure periods shall be entered into the Contractor's network analysis and monitored throughout the contract duration. The Contractor shall strictly adhere to specified Approved Lock Closure Periods. The specified duration of the closure periods will not be lengthened. The Contractor is required to obtain and coordinate the necessary resources to perform the designated work in the allotted closure periods.

(1) During the period of this construction contract, the lock will be continuously open to river traffic except for Approved Lock Closure Periods. The Contractor may be required to schedule work using multiple shifts, multiple crew operations, and work on weekends in order to complete the work. The Contractor shall be responsible for monitoring river conditions. Should ice conditions which would impede river transportation be anticipated, the Contracting Officer and the Contractor shall determine a path forward and payment will be made in accordance with Contract Clause entitled, "Changes". All impacts to navigation for Approved Lock Closure Periods shall be identified in the contractor's schedule and coordinated with and approved by the Lockmaster a minimum of three weeks in advance of the anticipated closure date. Any construction operations which impede lock operations along the landwall outside the scheduled lock closures will not be allowed unless coordinated with the Lockmaster. Upon identification of any additional changes in any previously scheduled impacts to navigation, the Contractor shall inform and coordinate with the Lockmaster as soon as possible, but no later than 7 days prior to the scheduled impact. The Lockmaster shall be given sufficient time to review and approve any changes.

(2) Approval for Lock Closure Periods. Lock Closure Periods will be provided to complete placement of concrete at each of the locations shown. To complete concrete placement at each location, it is anticipated that multiple lifts will be required. The Contractor shall take every step necessary to schedule placement of concrete lifts at multiple locations during a scheduled Lock Closure Period to minimize the total number of Lock Closures needed to complete the work. When the Contractor claims to be ready to perform tasks for which a lock closure period has been assigned, the Contractor and the Contracting Officer shall verify compliance with the Contractor's approved Work Plan. Changes or substitute measures initiated by the Contractor must be approved by the Contracting Officer. Upon acceptance of the readiness of the Contractor, the Contracting Officer will close the lock to river traffic. The Contractor will allow time for this inspection, review and necessary corrective action in his network analysis.

(3) Lock Closure Period for Floating Mooring Bit/Line Hook Concrete.

The Contractor will be permitted an 8 hour continuous lock closure period to place each lift of concrete required for the Floating

Mooring Bit Recess/Line Hooks for each location. After each concrete lift closure period, the Contractor shall wait at least 24 hours until another lock closure is permitted in order to allow river traffic to pass the lock. The Contractor may work on this task outside the lock closure period provided that, in the determination of the Contracting Officer, river traffic will not be hindered.

(4) Lock Closure Period for Filling of the Existing Miter Gate Recess. The Contractor will be permitted a 12 hour continuous lock closure period to place each lift of concrete required for filling the existing miter gate recess. After each concrete lift closure period, the Contractor shall wait at least 24 hours until another lock closure is permitted in order to allow river traffic to pass the lock. The Contractor may work on this task outside the lock closure period provided that, in the determination of the Contracting Officer, river traffic will not be hindered.

(5) Sequencing of work on Lock 25 is to be determined by the Contractor and shall be submitted as a work plan for Government approval.

(6) The Contractor shall notify the Contracting Officer 14 days prior to scheduled concrete removal activities for Government survey of existing monolith joint bolts.

(7) Decommissioning of electrical conductors must be accomplished before drilling in monoliths which encase these conductors.

(8) Power and control for the dam shall be available continuously, except for temporary outages, not to exceed 4 hours, which are coordinated with the Lockmaster and approved by the Contracting Officer. The outages envisioned are for transferring between temporary and permanent power and control systems.

(9) Contractor must maintain safe access for lock operations personnel (foot traffic) between control building and dam at all times.

(10) Compressed air supply to the lock shall be continuous at all times during the construction period. Any disruptions to the compressed air supply to the lock shall be coordinated with the Lockmaster and approved by the Contracting Officer.

1.27 CONTRACTOR PERFORMANCE EVALUATIONS

In accordance with the provisions of Subpart 36.201(Evaluation of Contractor Performance) of the Federal Acquisition Regulation (FAR), construction contractor's performance shall be evaluated throughout the performance of the contract. The United States Army Corps of Engineers (USACE) follows the procedures outlined in Engineering Regulation 415-1-17 to fulfill this FAR requirement. For construction contracts awarded at or above $100,000.00, the USACE will evaluate contractor's performance and prepare a performance report using the Contractor Performance Assessment Reporting System (CPARS), which is a web-based system. After an evaluation (interim or final) is written up by the USACE, the contractor will have the ability to access, review and comment on the evaluation for a period of 30 days. Accessing and using CPARS requires specific software, called PKI certification, which is installed on the user's computer. The certification is a Department of Defense requirement and was implemented to provide security in electronic transactions. The certification software could cost approximately $110 - $125 per certificate per year and is purchased from an External Certificate Authorities (ECA) vendor.

Current information about the PKI certification process and for contacting vendors can be found on the web site: http://www.cpars.navy.mil/. If the Contractor wishes to participate in the performance evaluation process, access to CPARS and PKI certification is the sole responsibility of the Contractor.

1.28 SECURITY REQUIREMENTS
