PARTIAL FIRST FLOOR - AREA A - DDC CONSTRUCTION

GENERAL NOTES: CONSTRUCTION (APPLY TO ALL CONSTRUCTION SHEETS)

1. THE MECHANICAL DRAWINGS ARE DIAGRAMMATIC AND INDICATE APPROXIMATE LOCATION OF EQUIPMENT, PIPING, AND

DUCTWORK. MINOR ADJUSTMENTS AND OFFSETS SHALL BE PROVIDED WHERE REQUIRED AT NO ADDITIONAL COST TO THE

OWNER. COORDINATE CHANGES IN PIPE/DUCT ROUTING OR OTHER WORK WITH ENGINEER PRIOR TO PROCEEDING.

2. ALL WORK SHALL BE INSTALLED IN ACCORDANCE WITH MANUFACTURER'S RECOMMENDATIONS AND THE NORTH CAROLINA

STATE MECHANICAL CODE.

3. THE BUILDING PLANS ARE BASED ON INFORMATION PROVIDED BY THE OWNER. THE CONTRACTOR SHALL FIELD VERIFY ALL

DIMENSIONS, QUANTITIES, PIPE AND DUCT SIZES, AND CONDITIONS PRIOR TO WORK. OWNER WILL NOT APPROVE ANY CHANGE

ORDERS RESULTING FROM CONTRACTOR'S FAILURE TO FIELD VERIFY. DRAWINGS SHALL NOT BE SCALED TO DETERMINE

ACTUAL DIMENSIONS.

4. COORDINATE ALL WORK WITH GENERAL CONTRACTOR, ELECTRICAL CONTRACTOR AND CONTROLS CONTRACTOR. CONDUIT,

CONTROL WIRING AND PIPING SHALL BE ROUTED TOGETHER IN CHASES.

5. PROPER FIRE WATCH TO BE MAINTAINED AT ALL TIMES DURING WELDING OR OPEN FLAME USE.

6. ALL PENETRATIONS SHOULD BE REUSED TO EXTENT POSSIBLE. PATCH NEW AND EXISTING PENETRATIONS TO MATCH

EXISTING WALL CONSTRUCTION. TREAT CORRIDORS AND THE FLOOR AS FIRE RATED, FIRE CAULK ANY PENETRATIONS IN FIRE

WALLS.

7. THE BUILDING WILL BE OCCUPIED DURING CONSTRUCTION. COORDINATE WORK SO THAT UTILITIES ARE OPERATIONAL WHEN

NEEDED IN OCCUPIED AREAS AND FACILITY OPERATIONS ARE NOT INTERRUPTED. THIS MAY REQUIRE WORK ON WEEKENDS

AND NIGHTS.

8. HANGERS MUST BE SECURED TO STRUCTURE.

9. TYPICAL OF ALL SPACE TEMPERATURE SENSORS, NO EXPOSED SURFACE WIRING IS TO BE USED UNLESS THERE IS

CONFIRMATION THE NEW WIRING CANNOT BE RUN CONCEALED. DO NOT INSTALL SENSOR WIRING UNTIL AFTER A REVIEW WITH

THE ENGINEER.

10. ANY CONTROL WIRING ROUTED ABOVE THE CEILING SHOULD BE PLENUM RATED. WIRING SHOULD BE BUNDLED AND TIED UP

HIGH ON STRUCTURE.

11. DAMPER OPERATION VERIFICATION: CONTRACTOR SHALL VERIFY THE OPERABILITY OF ALL EXISTING CONTROL DAMPERS BEING

CONTROLLED UNDER THIS PROJECT. THE CONTRACTOR SHALL REMOVE THE EXISTING DAMPER ACTUATOR, SPRAY LIQUID

WRENCH AT ALL ROTATING LOCATIONS AND MANUALLY MANIPULATE THE DAMPER TO CONFIRM OPERATION. NOTIFY THE

ENGINEER OF ANY ISSUES.

12. THE CONTRACTOR IS RESPONSIBLE FOR FINDING AND ROUTING DEDICATED 120v CIRCUITS FOR THE DDC SYSTEM.

KEYED NOTES:

Existing pneumatic temperature sensor to be replaced with new DDC temperature sensor. Remove old pneumatic temperature sensor and patch/paint

wall to match existing. Route control wiring to sensor inside in the wall, using the existing pneumatic tubing, to the sensor plate at 48" AFF. Coordinate

final sensor location with Engineer. Typical.

AHU-11 in Mechanical loft above. Remove existing control valves and piping to approximately 6' from unit. Install new isolation valves, control valves w/

actuators and new run out piping to coils. Install new isolation and control valves to allow for wider unit in a future project. See Existing AHU Information

Schedule for valve Cv.

AHU suspended overhead. Remove existing control valves and piping. install new isolation valves, control valves w/ actuators and new run out piping to

coils. Install new isolation and control valves to allow for wider unit in a future project. See Existing AHU Information Schedule for valve Cv.

Provide new freezestats and damper actuators for AHU dampers. Adjust linkage as required for solid secure inner-connection. Confirm torque is

adequate for damper.
