1. MECHANICAL DEMOLITION DRAWINGS SHOWING EXISTING CONDITIONS HAVE BEEN

PREPARED BASED ON NON-DESTRUCTIVE FIELD OBSERVATION AND AS-BUILT DRAWINGS

PROVIDED BY THE OWNER. FIELD VERIFY EXISTING SYSTEMS BEFORE BEGINNING WORK.

NOTIFY ARCHITECT/ENGINEER IF EXISTING CONDITIONS ARE MATERIALLY DIFFERENT THAN

THOSE SHOWN ON THE PLANS.

2. BE FAMILIAR WITH EXISTING MECHANICAL SYSTEMS THAT WILL BE AFFECTED BY THE

DEMOLITION WORK. OBTAIN PERMISSION FROM THE OWNER'S REPRESENTATIVE TO SHUT

OFF SERVICES OR SYSTEMS THAT AFFECT AREAS BEYOND THE LIMITS OF THE IMMEDIATE

DEMOLITION AREA. INFORM THE OWNER’S REPRESENTATIVE OF THE REASON FOR AND

DURATION OF THE SHUTDOWN. MINIMIZE IMPACT TO OTHER AREAS. PROCEED WITH THE

SHUT-DOWN AFTER PERMISSION FROM THE OWNER IS GRANTED.

3. REMOVE EQUIPMENT, DUCTWORK THAT ARE INDICATED TO BE REMOVED IN A TIMELY

MANNER IN ACCORDANCE WITH THE GENERAL DEMOLITION SPECIFICATIONS. COORDINATE

WITH THE OWNER AND OTHER CONTRACTORS.

4. UNLESS EQUIPMENT TO BE REMOVED IS NOTED AS OWNER’S SALVAGE, DISPOSE OF

EQUIPMENT AND/OR MATERIALS INDICATED TO BE REMOVED PROMPTLY.

MECHANICAL – DEMOLITION NOTES

1. COORDINATE WORK WITH ALL OTHER TRADES AS DESCRIBED IN MECHANICAL GENERAL

NOTE #1.

2. PROVIDE A COMPLETE HVAC SYSTEM, INCLUDING SUPPLY, RETURN, EXHAUST, AND

VENTILATION DUCTWORK; MECHANICAL EQUIPMENT, SUPPORTS, AND ALL APPURTENANCES.

INSTALL ALL EQUIPMENT PER MANUFACTURER'S RECOMMENDATIONS. INSTALL SYSTEM TO

MEET ALL CITY AND STATE CODES AND REQUIREMENTS.

3. DRAWING PLANS, SCHEMATICS, AND DIAGRAMS INDICATE GENERAL LOCATION AND

ARRANGEMENT OF DUCT SYSTEM. INDICATED DUCT LOCATIONS, CONFIGURATIONS, AND

ARRANGEMENTS WERE USED TO SIZE DUCTS AND CALCULATE FRICTION LOSS FOR AIR-

HANDLING EQUIPMENT SIZING AND FOR OTHER DESIGN CONSIDERATIONS. INSTALL DUCT

SYSTEMS AS INDICATED UNLESS DEVIATIONS TO LAYOUT ARE APPROVED BY

ARCHITECT/ENGINEER.
