1. THESE GENERAL NOTES APPLY TO ALL MECHANICAL DRAWINGS IN THIS SET.

SHEET SPECIFIC NOTES ARE INDICATED ON EACH SHEET UNDER GENERAL

SHEET NOTES.

2. PROVIDE ALL MATERIALS, VALVES, HANGERS, SUPPORTS, ETC., AND PERFORM

ALL LABOR REQUIRED TO INSTALL A COMPLETE AND OPERABLE MECHANICAL

SYSTEM.

3. INSTALL ALL MECHANICAL EQUIPMENT AND APPURTENANCES IN ACCORDANCE

WITH MANUFACTURER'S RECOMMENDATIONS, AS INDICATED, AND AS

REQUIRED BY CODE. WHERE THE ABOVE REQUIREMENTS ARE IN CONFLICT,

PROVIDE THE MOST STRINGENT.

4. MECHANICAL DRAWINGS ARE SCHEMATIC IN NATURE AND MAY NOT SHOW

EVERY OFFSET, FITTING, AND CONNECTION NECESSARY FOR A COMPLETE

INSTALLATION. PROVIDE ADDITIONAL OFFSETS, FITTINGS, AND CONNECTIONS

REQUIRED FOR COMPLETE AND OPERABLE SYSTEM.

OTHER TRADES AND EXISTING CONDITIONS PRIOR TO BEGINNING WORK.

WORK MUST PROVIDE ACCESS FOR MAINTENANCE WITHOUT REQUIRING

REMOVAL OR DISASSEMBLY OF ADJACENT SYSTEMS.

6. INSTALL TEMPERATURE CONTROLS AT 48" ABOVE FINISHED FLOOR AND

COORDINATE WITH OTHER DEVICES LOCATED ON WALLS. COORDINATE WITH

ALL WALL-MOUNTED EQUIPMENT.

7. DESIGN AND PROVIDE SEISMIC SUPPORTS, ISOLATORS, AND RESTRAINT

DEVICES IN ACCORDANCE WITH STRUCTURAL SPECIFICATIONS. WHERE

SEISMIC SUPPORT REQUIREMENTS CONFLICT WITH ATFP REQUIREMENTS

PROVIDE THE MORE STRINGENT.

8. MECHANICAL WORK MUST BE IN ACCORDANCE WITH UFC 3-401-01, UFC 3-410-01,

UFC 4-213-10, THE INTERNATIONAL MECHANICAL CODE, AND APPLICABLE

ASHRAE AND NFPA STANDARDS.

9. THE CONTRACTOR SHALL PROTECT ALL SITE EQUIPMENT FROM

CONSTRUCTION DUST AND DEBRIS.

10. PATCH AND SEAL ALL VOIDS FROM THE REMOVAL OF PIPING, TUBING, OR

OTHER ASSOCIATED ITEMS FROM THE FLOOR, WALL, OR OTHER THROUGH

PENETRATIONS.

11. FIELD VERIFY EXISTING CONDITIONS AND COORDINATE PIPE ROUTES TO AVOID

INTERFERENCE WITH OTHER UTILITIES AND EQUIPMENT. PROVIDE THE

MINIMUM NUMBER OF ELBOWS AND OFFSETS NECESSARY FOR A COMPLETE

INSTALLATION. WHERE A CONFLICT IS IDENTIFIED NOTIFY THE CONTRACTING

OFFICER.

12. ROUTE NEW PIPING WITH CONSIDERATION OF SPACE USE WITH OTHER

TRADES. PIPE MUST NOT BLOCK SERVICE CLEARANCES FOR EQUIPMENT.

13. SUCTION CHAMBER, FLOOR DRAINS, FLOODING AND DRAINAGE FLUMES MAY BE

FLOODED AND HAVE CONTINOUS INFLUENT. THE CONTRACTOR SHALL

PROVIDE MEANS FOR ALL DEWATERING REQUIRED TO COMPLETE WORK AND

MAINTAIN DRY PUMPWELL DURING CONSTRUCTION.

14. CONTRACTOR SHALL NOT USE PUMPWELL DEWATERING AND DRAINAGE PUMPS

AND PIPING SYSTEMS FOR WATER REMOVAL DURING CONSTRUCTION PERIOD.

CONTRACTOR IS RESPONSIBLE FOR PROVIDING TEMPORARY DEWATERING

SYSTEMS TO SERVE ALL DRAINAGE AND DEWATERING FUNCTIONS DURING

ENTIRE CONSTRUCTION PERIOD. TYPICAL CONTINUOUS FLOW TO DOCK IS

APPROX. 300 GPM. PROVIDE ADDITIONAL CAPACITY TO HANDLE STORM

EVENTS.

15. DURING CONSTRUCTION PUMPWELL MUST BE SECURED AND ALL ACCESS

HATCHES REINSTALLED ANY TIME PUMPWELL IS UNMANNED. PROVIDE MEANS

FOR WEATHER PROTECTION ANYTIME ACCESS HATCHES ARE REMOVED.

16. THE CONTRACTOR MUST SEAL AND PROTECT PUMPWELL WITHIN 48 HOURS OF

EMERGENCY RESPONSE TO DESTRUCTIVE WEATHER OR OTHER EMERGENCY

DOCKING OPERATION.

17. DEMOLITION OF MECHANICAL ITEMS WIRED WITH POWER AND/OR CONTROL

MUST INCLUDE REMOVAL OF WIRING AND CONDUIT TO SOURCE. COORDINATE

WITH ELECTRICAL CONTRACTOR.

18. CONTRACTOR IS RESPONSIBLE FOR PROVIDING EQUIPMENT NEEDED FOR

LIFTING PUMPWELL ACCESS HATCHES AND FOR REMOVING ALL EQUIPMENT

LOCATED INSIDE OF THE PUMPWELL. RIGGING SHALL BE IN ACCORDANCE WITH

NAVFAC P-307, "MANAGEMENT OF WEIGHT HANDLING EQUIPMENT", LATEST

REVISION.

19. MULTIPLE REPAIR/REPLACEMENT PROJECTS WILL OCCUR CONCURRENT WITH

P-678 PROJECT WORK. THESE INCLUDE REPAIR OF DRY DOCK 8 CAISSON,

REPLACEMENT OF PUMPWELL 8 MAIN DEWATERING PUMP 2, AND

REPLACEMENT OF PUMPWELL 8 MAIN DEWATERING PUMP 3. COORDINATE WITH

CONTRACTING OFFICER FOR OTHER PROJECT SCHEDULES AND

CONSTRUCTION SEQUENCES.

20. CONTRACT LINE ITEMS (CLIN) ARE INDICATED ON SPECIFICATIONS AND PLAN

DRAWINGS ONLY. COORDINATE ALL WORK SHOWN ON SECTIONS, DETAILS,

SCHEDULES, ETC WITH ASSOCIATED CLIN(S).
