GENERAL NOTES (FOR ALL MECHANICAL DRAWINGS)

1. INFORMATION ON THE DRAWINGS HAS BEEN ASCERTAINED FROM EXISTING DRAWINGS AND FIELD

OBSERVATIONS. THIS INFORMATION IS AS ACCURATE AS CONDITIONS WOULD ALLOW. IT IS THE RESPONSIBILITY OF THE CONTRACTOR TO VISIT THE SITE, PRIOR TO BID, AND BECOME FAMILIAR WITH

THE EXTENT OF THE WORK REQUIRED. NO EXTRAS WILL BE ALLOWED FOR ALTERATIONS OF A

FORESEEABLE NATURE REQUIRED TO ACHIEVE THE END RESULT AS INDICATED BY CONTRACT

DOCUMENTS.

2. CONTRACTOR IS TO PROVIDE COMPLETE CONNECTIONS TO ALL EQUIPMENT.

3. CONTRACTOR SHALL MAKE ARRANGEMENTS FOR PARKING, COORDINATE ANY EQUIPMENT DOWNTIME, AND COORDINATE GENERAL WORK SCHEDULE WITH OWNER.

4. CONTRACTOR SHALL VISIT THE SITE BEFORE SUBMITTING BID, AND VERIFY DIMENSIONS AND EXISTING

CONDITIONS RELATED TO THE WORK.

5. ALL CUTTING, PATCHING AND CORE DRILLING FOR THE INSTALLATION OF NEW EQUIPMENT, DUCTS, HANGERS, ETC. SHALL BE HELD TO A MINIMUM AND BE ACCOMPLISHED IN A CAREFUL MANNER.

6. CONTRACTOR TO COORDINATE THE LOCATION OF ALL DUCTWORK, CEILING DEVICES, GRILLES, REGISTERS AND DIFFUSERS WITH REFLECTED CEILING PLAN AND STRUCTURE PRIOR TO BEGINNING

WORK.

7. DUCT DIMENSIONS GIVEN ARE OUTSIDE SHEET METAL DIMENSIONS.

8. MECHANICAL DRAWINGS ARE DIAGRAMMATIC AND DO NOT NECESSARILY INDICATE EVERY REQUIRED OFFSET, FITTING, ETC. DRAWINGS ARE NOT TO BE SCALED FOR DIMENSIONS. TAKE ALL DIMENSIONS

FROM ARCHITECTURAL DRAWINGS, CERTIFIED EQUIPMENT DRAWINGS AND FROM THE STRUCTURE

ITSELF BEFORE FABRICATING ANY WORK, VERIFY ALL SPACE REQUIREMENTS COORDINATING WITH OTHER TRADES, AND INSTALL THE SYSTEMS IN THE SPACE PROVIDED WITHOUT EXTRA CHARGES TO THE

OWNER.

9. THE OWNER AND ENGINEER ARE NOT RESPONSIBLE FOR THE CONTRACTOR'S SAFETY PRECAUTIONS OR

TO MEANS, METHODS, TECHNIQUES, CONSTRUCTION SEQUENCES, OR PROCEDURES REQUIRED TO

PERFORM HIS WORK.

10. ALL WORK SHALL BE INSTALLED IN ACCORDANCE WITH ALL APPLICABLE STATE CODES, LOCAL CODES

AND OWNER'S STANDARDS INDICATED BY THE CONSTRUCTION DOCUMENTS.

11. ALL EXTERIOR WALL AND ROOF PENETRATIONS SHALL BE SEALED WATERPROOF.

12. ALL MECHANICAL WORK UNDER THIS CONTRACT IS TO FIVE (5) FEET OUTSIDE THE BUILDING.

13. XX-## REFERS TO EQUIPMENT DESIGNATION. SEE SPECIFICATIONS AND EQUIPMENT SCHEDULES FOR

FURTHER INFORMATION IN REFERENCE TO THAT DESIGNATED PIECE OF EQUIPMENT.

14. DRAWINGS INDICATE UNITS IN IP UNITS. WHERE SUBMITTED MATERIAL USES METRIC UNITS, SUCH AS PRE-INSULATED PEX, THE SUBMITTED MATERIAL INSIDE FREE AREA SHALL BE EQUIVALENT OR LARGER

THAN THE IDENTIFIED IP PIPE SIZE FREE AREA.

15. CONTRACTOR SHALL FIELD COORDINATE EXACT LOCATION OF RADIANT / SNOWMELT PEX TUBING WITH

STRUCTURAL / ARCHITECTURAL DRAWINGS, INDUSTRIAL EQUIPMENT DRAWINGS, AND GENERAL

CONTRACTOR PRIOR TO CONCRETE POUR.
