GENERAL NOTES:

EXISTING ROOF IS UNDER WARRANTY BY "JOHNS MANSVILLE". ALL ROOFING WORK SHALL BE PERFORMED BY TADCO, THE APPROVED CONTRACTOR THAT CAN MAINTAIN SUCH WARRANTY. REFER TO DIV. 7 SPECIFICATIONS FOR MORE INFORMATION. TADCO CONTACT INFORMATION: EDGAR PENA ( EDGAR@TADCOROOFING.COM ), CARLOS CORONADO (CCORONADO@TADCOROOFING.COM).

THE NEW ROOFTOP UNITS (RTUS) AND ROOF CURBS HAVE BEEN SELECTED WITH A MAXIMUM HEIGHT LIMITATION TO ENSURE THAT EQUIPMENT IS NOT VISIBLE FROM STREET-LEVEL VIEWPOINTS AT ADJACENT CORNERS. THIS DESIGN APPROACH HAS BEEN REVIEWED AND APPROVED BY THE TEXAS HISTORICAL COMMISSION (THC). CONTRACTOR SHALL STRICTLY MAINTAIN THE SPECIFIED MAXIMUM INSTALLATION HEIGHTS FOR ALL RTUS AND ROOF CURBS. ALTERNATIVE EQUIPMENT MANUFACTURERS MAY BE PROPOSED (REFER TO SPECIFICATIONS); HOWEVER, ALL PROPOSED EQUIPMENT SHALL COMPLY WITH THE ESTABLISHED MAX. HEIGHT

RESTRICTIONS. REFER TO MECHANICAL ELEVATIONS.

SEQUENCES OF CONSTRUCTION:

THE DEMOLITION AND NEW INSTALLATION WORK SHOWN IN THE DRAWINGS IS PRESENTED AS A COMPLETE SCOPE FOR CLARITY OF DESIGN INTENT. HOWEVER, THIS DOES NOT IMPLY THAT ALL WORK IS TO BE PERFORMED SIMULTANEOUSLY. DUE TO THE BUILDING’S CONTINUOUS OCCUPANCY AND OPERATIONAL NEEDS, THE WORK SHALL BE CAREFULLY PHASED AND COORDINATED TO MINIMIZE DISRUPTION TO COUNTY

OPERATIONS.

THE FOLLOWING SEQUENCE OF CONSTRUCTION IS PROVIDED TO GUIDE THE CONTRACTOR IN DEVELOPING A DETAILED PHASING PLAN THAT ENSURES SYSTEM CONTINUITY, MAINTAINS BUILDING SERVICES, AND ALIGNS WITH ACCEPTABLE SHUTDOWN WINDOWS AND ACCESS LIMITATIONS. CONTRACTOR SHALL COORDINATE CLOSELY WITH CAMERON COUNTY FACILITIES STAFF THROUGHOUT THE DURATION OF THE PROJECT.

THE AIR HANDLING UNITS (AHUS) SHALL BE REPLACED WITH THEIR ASSOCIATED ROOFTOP UNITS (RTUS) IN THE FOLLOWING ORDER TO MINIMIZE DISRUPTION TO BUILDING OCCUPANTS AND ENSURE CONTINUITY OF SERVICE:

AHU-11 – COMMISSIONERS COURT SOUTH

AHU-16 – COMMISSIONERS COURT SOUTH

AHU-15 – COMMISSIONERS COURT NORTH

AHU-14 – 3RD FLOOR OFFICES NORTHEAST

AHU-10 – 2ND FLOOR OFFICES NORTH

AHU-8 – 2ND FLOOR OFFICES NORTH

AHU-12 – 3RD FLOOR OFFICES NORTHWEST

AHU-9 – 2ND FLOOR OFFICES SOUTHWEST

AHU-13 – 3RD FLOOR OFFICES SOUTHWEST

CONTRACTOR SHALL FOLLOW THIS SEQUENCE UNLESS A REVISED PHASING PLAN IS SUBMITTED AND APPROVED BY THE ENGINEER AND OWNER. CONTRACTOR SHALL ALLOW FLEXIBILITY TO ADJUST THE ORDER OF UNIT REPLACEMENTS AS NEEDED BY THE OWNER WITHOUT ADDITIONAL COST, PROVIDED THE OVERALL

SCOPE OF WORK REMAINS UNCHANGED.

CONSTRUCTION SEQUENCE:

RELOCATE LIGHTNING PROTECTION SYSTEM & MARK EQUIPMENT LOCATIONS:

RELOCATE EXISTING LIGHTNING PROTECTION SYSTEM CABLING AS REQUIRED TO CLEAR ROOFTOP WORK AREAS. MARK THE LOCATIONS OF ALL NEW RTUS AND ROOF HATCHES TO VERIFY THAT LAYOUT WILL NOT

INTERFERE WITH EXISTING ROOFTOP FEATURES OR STRUCTURE.

INSTALL ROOF HATCHES FOR EQUIPMENT REMOVAL:

PROVIDE NEW 48" X 48" ROOF HATCHES AS INDICATED IN THE DRAWINGS. THESE WILL SERVE AS ACCESS POINTS FOR THE DEMOLITION AND REMOVAL OF ATTIC-MOUNTED AIR HANDLING UNITS. COORDINATE

OPENING SIZE AND FRAMING DETAILS WITH STRUCTURAL DRAWINGS.

INSTALL ROOF-MOUNTED CHW PIPING & TIE-INS:

INSTALL NEW CHILLED WATER (CHW) PIPING LOOP ON THE ROOF AS SHOWN. TIE INTO THE EXISTING CHW SYSTEM AT DESIGNATED LOCATIONS USING FREEZE TAPS AND ISOLATION VALVES TO ALLOW FOR STAGED

CONNECTIONS AND MINIMAL SYSTEM DISRUPTION.

RECONNECT CHW TO EXISTING AHU-17 & AHU-18 (UNITS TO REMAIN):

EXTEND NEW CHW PIPING FROM THE ROOF TO SERVE AHU-17 AND AHU-18, WHICH ARE TO REMAIN OPERATIONAL IN THE ATTIC. DEMOLISH THE EXISTING ATTIC CHW LOOP SERVING THESE UNITS TO THE

EXTENT POSSIBLE ONCE THE NEW CONNECTIONS ARE ACTIVE.

PERFORM STRUCTURAL AND ROOFING WORK PER STRUCTURAL DRAWINGS:

PERFORM ALL STRUCTURAL DEMOLITION, REINFORCEMENT, ROOF CURB MODIFICATIONS, AND ROOFING WORK AS SHOWN IN THE STRUCTURAL DRAWINGS. WORK SHALL BE COMPLETED ON A ONE-FOR-ONE

BASIS, ALIGNED WITH THE SEQUENCE OF EQUIPMENT REMOVAL AND REPLACEMENT.

SEQUENTIAL DEMOLITION AND REPLACEMENT OF AHUS AND RTUS (ONE-FOR-ONE):

DEMOLISH EACH ATTIC AIR HANDLER AND IMMEDIATELY INSTALL THE CORRESPONDING ROOFTOP UNIT (RTU) ON A ONE-FOR-ONE BASIS. EACH REPLACEMENT SHALL INCLUDE ALL ASSOCIATED COMPONENTS, INCLUDING BUT NOT LIMITED TO:

NEW DUCTWORK AND DUCT HEATERS

CHW PIPING, VALVES, AND INSULATION

ROOF CURB, ROOFING, AND STRUCTURAL WORK AS REQUIRED

CONDENSATE PIPING AND ROUTING

SUPPORTS, ACCESSORIES, AND WEATHERPROOFING

THIS SEQUENCE SHALL INCLUDE ALL NECESSARY CRANE LIFTS, RIGGING, STAGING, AND ROOFTOP LOGISTICS. CONTRACTOR SHALL BE RESPONSIBLE FOR ALL CRANE SERVICES, ACCESS COORDINATION, ROOFTOP PROTECTION, AND RELATED PERMITTING.

INSTALL ELECTRICAL AND CONTROLS INFRASTRUCTURE (PER UNIT):

PROVIDE NEW ELECTRICAL SERVICE, DISCONNECTS, AND CONTROL WIRING FOR EACH RTU DURING ITS

RESPECTIVE INSTALLATION. WORK SHALL BE PERFORMED IN COORDINATION WITH MECHANICAL

CHANGEOVERS. CRANE AND ROOFTOP LOGISTICS FOR CONDUIT OR PANELBOARD ACCESS SHALL BE

INCLUDED AS REQUIRED.

DEMOLISH REMAINING CHW PIPING IN ATTIC:

ONCE ALL RTUS ARE OPERATIONAL AND COMMISSIONED, DEMOLISH THE REMAINING CHILLED WATER

PIPING IN THE ATTIC THAT IS NO LONGER IN SERVICE.

BASEMENT – CHW VALVE & CONTROLS REPLACEMENT:

REPLACE CHILLED WATER VALVES, ACTUATORS, AND CONTROL COMPONENTS IN THE BASEMENT

MECHANICAL ROOM. WORK SHALL BE PERFORMED ON A ONE-FOR-ONE BASIS TO MAINTAIN SYSTEM

FUNCTIONALITY THROUGHOUT.
