There will be no restrictions imposed on Contractor's work hours for this project.

1.16.3 Coordination with Lock and Dam Operations

The Contractor shall perform all work in a manner that will not interfere with the duties of the project personnel. Particular care shall be taken during all operations under this contract to prevent damage to any operating equipment or facilities at the project. The Contractor shall continuously maintain safe access to all areas of the lock and dam project for project operating personnel, during every phase of the work, unless otherwise directed by the Contracting Officer.

1.16.4 Government Access to the Site

Government access to the site shall be maintained at all times.

1.16.5 Contractor Coordination and Scheduling

In accordance with Section 01 32 01.00 10 PROJECT SCHEDULE, the Contractor shall submit a detailed project schedule for his work to the Contracting Officer. All necessary adjustments in the Contractor's work schedule shall be coordinated and approved by the Contracting Officer.

1.16.6 Coordination with Dam Gate Operations

1.16.6.1 Control of Flow Over Fixed Crest Weir

It is noted that the Government has installed flash boards on top of the fixed crest weir to minimize flow over the fixed crest weir. The Government will be responsible for maintaining the flash boards, and the

SECTION 01 30 00.10 Page 16 removal of accumulated debris.

1.16.6.2 Operation of Dam Gates During Contract Work

At the end of this Section of the Specifications is a table showing schedule of existing gate operations, and a table showing schedule of gate operations during various phases of construction. The Contractor is alerted that gate operations may vary from the schedules shown as a result of the proposed painting work which will require that individual gates will be out of operation during cleaning and painting.

1.16.6.3 Unanticipated (Emergency) Operations

The Government may open restricted (closed) gates upon short notice to the contractor in order to prevent upstream flooding. Once the unrestricted (opened) gates have been open full, the lockmaster will begin opening the restricted (closed) gates if required to maintain the upper pool at or near the normal level. If any work in progress is damaged as a result of these operations, the contractor will be fairly compensated in accordance with Section 00700 CONTRACT CLAUSES, paragraph "CHANGES".

1.17 POOL LEVELS

The Government will not attempt to vary the pool levels for the convenience of the Contractor during the progress of the work. The minimum upper pool level, termed "normal pool", is El. 743.5 (Project Lower Gage = 17.5 feet) as shown on the drawings. The actual upper pool elevation will usually be within one foot above this level, except during high flow. The minimum lower (normal) pool level is elevation 726.9, and the pool will usually be within a few feet of this level, except during high flow. It is noted that Charleroi Locks and Dam is closed to traffic at an upper gage reading of

13.0 feet and/or a lower gage reading of 29.0 feet. The Contractor should refer to the hydrographs, Stage-Discharge relationships, and the Stage-Duration curves when planning the various work activities for this project. This information is shown on the drawings and Tables A through E at the end of this Section.

1.17.1 Hydrographs

The stage hydrographs represent water surface elevations, and should be used by the Contractor to have knowledge of historical trends. For Charleroi L/D, the hydrographs were developed from actual Lockmaster stage records.

1.17.2 Stage-Discharge

The Contractor shall refer to the stage-discharge curves on the drawings to determine river discharge (cubic feet per second) for various river stages. Tables A and C at the end of this section also tabulate discharges corresponding to key river stages at Charleroi L/D that are significant in relationship to this project. Table A applies to the upper pool and Table C to the lower pool.

1.17.3 Stage-Duration

The Contractor shall refer to the Stage-Duration curves on the drawings to determine the percentage of time for which various water surface elevations were equaled or exceeded during the hydrograph's period of record. Tables A and C at end of this section also tabulate monthly stage-duration

SECTION 01 30 00.10 Page 17 relationships at Charleroi L/D upper and lower pool, respectively. To assist in determining discharge-duration relationships, obtain the relevant stage for a particular discharge from the appropriate stage-discharge relationship, and relate it to the stage-duration curve.

1.17.4 Velocities

Tables B (upper pool), D (lower pool) and E (lower pool, after pool changed) at the end of this section provide river velocities corresponding to various discharges and the percentage of time each month that these velocities are equaled or exceeded. Tables B, D and E should be referred to when planning the various work activities for this project. Table E shows excedence durations after the level of Pool 3 is changed. This condition may occur, at the Government's discretion, sometime during this contract.

1.18 SAFETY AND HEALTH REQUIREMENTS

Safety and Health Requirements shall conform to Section 01 35 26 GOVERNMENT SAFETY, EM 385-1-1, and the requirements of the Occupational Safety and Health Administration. Where provisions of EM 385-1-1 vary with OSHA requirements, the more stringent requirements shall be applied.
