A. NOT ALL ABBREVIATIONS AND SYMBOLS SHOWN MAY BE USED ON THIS PROJECT.

B. FOR LOCATIONS AND SIZES OF WALL OPENINGS SEE ARCHITECTURAL DRAWINGS.

C. PROVIDE READY ACCESS TO VALVES, DAMPERS, COILS AIR FILTERS, AND OTHER DEVICES. INSTALL ACCESS DOORS TO

PROVIDE ADEQUATE CLEARANCES FOR DIRECT ACCESS.

D. FOR LOCATION OF CEILING DIFFUSERS AND GRILLES SEE ARCHITECTURAL REFLECTED CEILING PLANS.

E. DESIGNATE A PERSON TO BE RESPONSIBLE FOR FIRE PROTECTION DURING WELDING AND CUTTING OPERATIONS.

PERSON PERFORMING FIRE PROTECTION DUTIES MUST NOT BE SAME INDIVIDUAL THAT IS PERFORMING WELDING OPERATIONS. COMPLY WITH OSHA STANDARDS FOR WELDING IN 29 CFR-1910 AND 29 CFR-1926. PROVIDE TEMPORARY FIRE EXTINGUISHERS DURING CONSTRUCTION. WELDING MUST BE SCHEDULED IN WRITING WITH COR AND MUST BE

PERFORMED OUTSIDE OF FACILITY OR IN SAFE LOCATION TO BE DETERMINED BY COR.

F. FOR WELDING THAT MUST BE PERFORMED INSIDE THE BUILDING, PROVIDE LOCAL MECHANICAL VENTILATION DURING WELDING DUCTED TO OUTSIDE, APPROVED BY FAA AND ACGIH. MINIMIZE WELDING WITHIN THE BUILDING WHEREVER

POSSIBLE.

G. WELDING POWERED FROM FACILITY ELECTRICAL SYSTEM IS PROHIBITED. CONNECT METAL TO BE WELDED TO A GOOD EARTH GROUND. FACILITY STRUCTURAL STEEL OR PIPING MUST NOT BE USED AS A GROUND PATH.

H. AIR FLOW QUANTITIES SHOWN ARE FLOW QUANTITIES AT SITE ELEVATION.

I. INSTALL EQUIPMENT PER MANUFACTURER'S RECOMMENDATIONS AND INSTRUCTIONS.

J. LOCATIONS, SIZES, CLEARANCES AND CONFIGURATIONS OF EQUIPMENT SHOWN ARE BASED ON SPECIFIC SCHEDULED MANUFACTURERS AND MODEL NUMBERS. SUBSTITUTION OF SUCH EQUIPMENT MANUFACTURERS WILL REQUIRE THE CONTRACTORS PRIOR VERIFICATION OF CONFORMANCE PER THE REQUIREMENTS OF LOCATION, SIZE CLEARANCES AND CONFIGURATION AS COMPARED TO SPACE ALLOCATED TO HOUSE SPECIFIC EQUIPMENT. RESUBMIT PROPOSED EQUIPMENT TO CONTRACTING OFFICER'S REPRESENTATIVE (COR) FOR APPROVAL, PRIOR TO INSTALLATION.

K. CONSTRUCT, INSTALL, AND INSULATE SUPPLY AND RETURN AIR DUCTWORK AS SPECIFIED; INSPECT DUCTWORK, SUPPORTS AND INSULATION (NEW AND EXISTING) FOR DAMAGE OR FAULTY INSTALLATION. REPLACE, OR REPAIR AS REQUIRED SO THAT FINAL INSTALLATION IS ADEQUATELY SEALED FROM LEAKS, FREE OF DEFECTS, CLEANED, AND IN ACCORDANCE WITH SPECIFICATIONS. PROVIDE EXTERIOR DUCTWORK INSULATION ON ALL EXISTING DUCTWORK THAT

IS UNINSULATED.

L. PROVIDE FIRE AND FIRE/SMOKE DAMPERS IN PENETRATIONS OF FIRE RATED FLOORS, WALLS AND PARTITIONS IN

ACCORDANCE WITH ALL APPLICABLE CODES AND STANDARDS.

M. LIMIT USE OF FLEXIBLE DUCTS TO AIR OUTLET CONNECTIONS. FLEXIBLE DUCT CONNECTIONS MUST NOT EXCEED 5'-0" IN LENGTH. AIR DEVICES INSTALLED IN A HARD CEILING WITHOUT ACCESS MUST BE COMPLETELY HARD-DUCTED.

EXHAUST DUCTWORK CONNECTIONS MUST BE COMPLETELY HARD-DUCTED.

N. PROVIDE WIRE MESH SCREENS FOR DUCT OPENINGS WITHOUT GRILLES.

O. FOR AREAS WITH INACCESSIBLE VOLUME DAMPERS, PROVIDE DAMPER WITH FLEXIBLE METAL CABLE OPERATORS FOR

REMOTE OPERATION OF THE DAMPER THROUGH FACE OF DIFFUSER, GRILLE OR REGISTER.

P. PROVIDE A DETAILED SCHEDULE FOR DEMOLITION OF HVAC EQUIPMENT AND INSTALLATION OF NEW HVAC SYSTEMS.

COORDINATE WITH COR PRIOR TO REMOVAL OF EQUIPMENT. WHERE INDICATED ON DRAWINGS, PROVIDE TEMPORARY COOLING SYSTEMS. SUCH SYSTEMS MUST REMAIN IN OPERATION THROUGHOUT REMOVAL AND REPLACEMENT OF

EQUIPMENT.

Q. PRIOR TO THE DEMOLITION OF ITEMS WHICH HAVE UTILITIY CONNECTIONS (WATER, ELECTRICITY, GAS ETC.) ARRANGE WITH COR TO LOCATE SHUT-OFF VALVES, PANEL BOXES AND OTHER CONTROL ELEMENTS. ONLY FAA PERSONNEL MAY

SHUT OFF, ISOLATE EQUIPMENT AND BRING EQUIPMENT BACK ONLINE.

R. REFER TO STRUCTURAL SHEET S010 AND S013 FOR APPLICABLE WIND LOAD CRITERIA.

S. PROVIDE STAINLESS STEEL FOR ALL EXTERIOR HARDWARE, INCLUDING BUT NOT LIMITED TO, BOLTS, WASHERS, CLAMPS, AND UNISTRUTS. WHERE STAINLESS STEEL IS NOT AVAILABLE, PROVIDE HARDWARE WITH ANTI-CORROSION

COATING FOR RUST PREVENTION.

T. THE REFRIGERANT CONTAINED IN SYSTEMS BEING DEMOLISHED MUST BE REMOVED PRIOR TO DEMOLITION, RECOVERED AND BROUGHT TO A EPA-CERTIFIED RECLAIMER BY AN EPA-CERTIFIED TECHNICIAN.

U. PROVIDE DUCTWORK CLEANING FOR ALL EXISTING TO REMAIN DUCTWORK IN THE AIR TRAFFIC CONTROL TOWER

(ATCT).

V. UNIT DISASSEMBLY MUST BE CONDUCTED BY A CERTIFIED TECHNICIAN.

W. REFER TO SPECIFICATIONS FOR TESTING, ADJUSTING, AND BALANCING REQUIREMENTS.

X. ALL ITEMS REMOVED FOR REUSE MUST BE INSPECTED FOR STATUS AND REPORTED TO COR. ANY DEFICIENCIES MUST

BE NOTED PRIOR TO REMOVAL.

Y. DRAWINGS ARE DIAGRAMMATIC IN NATURE. IT IS THE RESPONSIBILITY OF THE CONTRACTOR TO SURVEY AND VERIFY EXISTING CONDITIONS PRIOR TO STARTING WORK. EXISTING CONDITIONS SHOWN ARE BASED ON AVAILABLE INFORMATION PROVIDED BY THE FAA. WORK MUST BE COORDINATED WITH ACTUAL EXISTING CONDITIONS.
