1. THE FACILITY WILL REMAIN IN OPERATION DURING CONSTRUCTION. COORDINATE ALL

SHUTDOWNS AND CONSTRUCTION ACTIVITY WITH FACILITIES STAFF.

2. SIZE AND LOCATION OF ALL PIPING AND OTHER MECHANICAL EQUIPMENT IS APPROXIMATE.

CONTRACTOR SHALL SITE VERIFY THE LOCATION OF EXISTING PIPING AND EQUIPMENT AND

CONSTRUCT WORK FROM FIELD DIMENSIONS. CONTRACTOR SHALL MAKE ADJUSTMENTS NECESSARY

TO ACCOMMODATE MINOR DEVIATIONS AT NO COST TO OWNER.

3. FINE (LIGHT) LINE WORK INDICATES EXISTING PIPING AND OTHER MECHANICAL EQUIPMENT. BOLD

(HEAVY) LINE WORK INDICATES NEW PIPING AND OTHER MECHANICAL EQUIPMENT.

4. IT IS RESPONSIBILITY OF THE CONTRACTOR TO PROVIDE CUTTING AND PATCHING TO

ALLOW THE INSTALLATION OF MATERIALS AND EQUIPMENT AS SPECIFIED AND SHOWN ON DRAWINGS.

DEMOLITION NOTES

1. REVIEW DEMOLITION DRAWINGS FOR ITEMS TO REMAIN, TO BE RETAINED FOR RELOCATION, OR TO BE SALVAGED TO THE OWNER. REFER TO ARCHITECTURAL DOCUMENTS FOR ADDITIONAL REQUIREMENTS.

2. DEMOLISH EQUIPMENT, FIXTURES, DEVICES, PIPING, CONDUIT, FITTINGS, AND APPURTENANCES INTERIOR TO THE BUILDING THAT ARE MADE OBSOLETE BY THE NEW WORK AND/OR ARE ABANDONED

AND NO LONGER IN USE.

3. PROTECT AND MAINTAIN OPERABILE EXISTING EQUIPMENT, FIXTURES, OR SYSTEMS THAT ARE

INDICATED TO REMAIN, INCLUDING ELECTRICAL POWER, CONTROLS, AND RELATED SYSTEMS

REQUIRED TO MAINTAIN OPERABILITY.

4. EXISTING CONDITIONS SHOWN ARE BASED ON RECORD DOCUMENTS AND LIMITED FIELD

OBSERVATIONS OF ACCESSIBLE AREAS AND MAY NOT SHOW THE ENTIRE SCOPE OF DEMOLITION

WORK. OMISSION OF EXISTING EQUIPMENT, FIXTURES, DEVICES, PIPING, CONDUIT, FITTINGS, AND APPURTENANCES FROM THE DEMOLITION DRAWINGS DOES NOT RELIEVE THE CONTRACTOR OF THE RESPONSIBILITY TO PROVIDE DEMOLITION OF SYSTEMS THAT ARE MADE OBSOLETE BY THE NEW WORK, ARE ABANDONED, OR AS OTHERWISE REQUIRED TO PERFORM THE WORK DESCRIBED HEREIN.

5. PROTECT AND MAINTAIN SERVICES TO REMAIN OPERATIONAL THAT PASS THROUGH THE AREA OF CONSTRUCTION. WHERE IT IS NOT POSSIBLE TO MAINTAIN THESE SERVICES INTACT, REPLACE, REROUTE, MODIFY, OR PROVIDE NEW AS REQUIRED TO MAINTAIN SERVICES.

6. EQUIPMENT REMOVAL INCLUDES EXISTING PNEUMATIC CONTROLS COMPONENTS AND PERIPHERALS.

PNEUMATIC CONTROLS REMOVAL INCLUDES, BUT IS NOT LIMITED TO: COMPRESSED AIR TUBING, THERMOSTATS, SWITCHES, PNEUMATIC CONTROLLERS, AND DAMPER OPERATORS.
