1. PROVIDE ALL MATERIALS AND EQUIPMENT AND PERFORM ALL

LABOR REQUIRED TO INSTALL COMPLETE AND OPERABLE

MECHANICAL SYSTEM AS INDICATED ON THE DRAWINGS, AS

SPECIFIED AND AS REQUIRED BY ALL NATIONAL, STATE AND

LOCAL CODES.

2. CONTRACT DRAWINGS FOR MECHANICAL WORK ARE

DIAGRAMMATIC AND ARE INTENDED TO CONVEY SCOPE AND

GENERAL ARRANGEMENT ONLY. IT IS THE CONTRACTORS

RESPONSIBILITY FOR INSTALLING ALL MATERIALS PER SMACNA

STANDARDS AND THE MANUFACTURER'S STANDARDS.

3. ALL EXISTING SYSTEM INFORMATION AND/OR LOCATIONS

ARE PROVIDED BY THE OWNER OR BY A 3RD PARTY.

IT IS THE CONTRACTORS RESPONSIBILITY TO VERIFY ALL MEP

SERVICES ARE LOCATED AS DESIGNED BEFORE BIDDING THE

PROJECT. IN OCCURRENCES WHERE EXISTING DOES NOT

MATCH DESIGNED, IT IS THE CONTRACTORS RESPONSIBILITY

TO NOTIFY THE OWNER, ARCHITECT, & ENGINEER

BEFORE PROCEEDING. IF ANY DISCREPANCIES ARE NOT

IDENTIFIED AT BIDDING, THE COST SHALL BE ABSORBED BY

THE CONTRACTOR AND NOT PASSED ONTO THE OWNER OR

ENGINEER OF RECORD.

4. COORDINATE CONSTRUCTION OF ALL MECHANICAL WORK WITH

ARCHITECTURAL, STRUCTURAL, CIVIL, ELECTRICAL WORK, ETC.,

SHOWN ON THE OTHER CONTRACT DRAWINGS.

5. WHEN TWO OR MORE ITEMS OF THE SAME TYPE OF EQUIPMENT

ARE REQUIRED, THE PRODUCT OF ONE MANUFACTURE SHALL BE

USED.

6. ALL MISCELLANEOUS STEEL REQUIRED TO ENSURE PROPER

INSTALLATION AND AS SHOWN IN DETAILS FOR PIPING SHALL BE

FURNISHED AND INSTALLED BY THE MECHANICAL CONTRACTOR.

7. LOCATION AND SIZES OF ALL FLOOR, AND WALL, OPENINGS

SHALL BE COORDINATED WITH ALL OTHER TRADES.

8. ALL DEMOLITION ACTIVITIES SHALL BE PERFORMED SO AS TO

PROVIDE MINIMAL DISRUPTION TO THE NEIGHBORING TENANTS.

9. ALL SAW CUTTING SHALL BE PERFORMED AFTER HOURS SO THAT

OPERATION DOES NOT DISTURB NEIGHBORING TENANTS. THERE

SHALL BE NO GAS POWERED EQUIPMENT IN TENANT AREAS.
