NOTES

1. See specification section 02 41 07 - Modification or Removal of

Existing Features and 03 81 10 - Concrete Removal.

2. See Dwg. 1745-417-115 for bypass channel demolition detail and

Dwg. 1745-417-116 for fish return demolition detail.

3. Scales shown on views are for drawings printed at full scale.

4. Appropriate worker protection shall be used when modifying galvanized components.

5. Coat all cut faces with liquid galvanizing paint.

6. Stockpile removed baffle panels on site as directed by COR.

7. Components shall remain as part of the facility, unless their removal is specified in the drawings or specs. Any components temporarily removed for convenience of the contractor shall be restored after project completion.

8. Fish return transition has been modified and differs from that shown on Information Drawings. Modification is shown in Detail 4.
