DOCUMENTS

13 FEB 2025

1. THE MECHANICAL DRAWINGS SHOW THE GENERAL DESIGN, ARRANGEMENT,

& EXTENT OF THE MECHANICAL SYSTEM. BECAUSE OF THE SMALL SCALE OF

THE DRAWINGS, THESE DRAWINGS DO NOT SHOW ALL OFFSETS, BENDS, OR

ELBOWS NECESSARY FOR THE COMPLETE INSTALLATION IN THE SPACE

PROVIDED. CONTRACTOR SHALL MAKE ALTERATIONS AS MAY BE

NECESSARY TO MAKE THE SYSTEM COMPLETE & OPERATIONAL IN

ACCORDANCE WITH THE DESIGN INTENT.

2. MAJOR DEVIATIONS SUCH AS CHANGES IN SIZES, WEIGHTS, QUANTITIES, OR

MATERIAL REQUIRE PRIOR APPROVAL BY THE DESIGN ENGINEER AND

OWNER.

3. THE DRAWINGS & SPECIFICATIONS HAVE BEEN PREPARED TO SUPPLEMENT

EACH OTHER & SHALL BE INTERPRETED AS AN INTEGRAL UNIT WITH THE

ITEMS SHOWN ON ONE & NOT THE OTHER BEING FURNISHED & INSTALLED

AS THOUGH SHOWN AND CALLED OUT IN BOTH DOCUMENTS. THE

SPECIFICATIONS SHALL SUPERCEDE THE DRAWINGS WHEN IN CONFLICT.

4. THE ENTIRE MECHANICAL INSTALLATION SHALL CONFORM TO THE

REQUIREMENTS OF THE MOST RECENTLY ADOPTED BUILDING CODES,

MECHANICAL CODE, PLUMBING CODE, ELECTRICAL CODE, & ALL OTHER

APPLICABLE CITY, COUNTY, STATE, & FEDERAL CODES & REGULATIONS IN

EFFECT.

5. THE ENTIRE MECHANICAL INSTALLATION SHALL CONFORM TO ALL CODES,

RULES, REGULATIONS, & REQUIREMENTS OF THE BUILDING OWNER.

6. ALL MECHANICAL COMPONENTS AND EQUIPMENT SHALL BE INSTALLED TO

CONFORM WITH ANY APPLICABLE LOCAL SEISMIC REQUIREMENTS.

7. PRIOR TO FABRICATION & INSTALLATION OF ANY MECHANICAL COMPONENT

THE CONTRACTOR SHALL COORDINATE THE INSTALLATION OF ALL

MECHANICAL WORK WITH ALL OTHER BUILDING TRADES, INCLUDING

BUILDING TRADES HIRED DIRECTLY BY THE OWNER. WHERE CONFLICTS

MAY OCCUR, THEY SHALL BE RESOLVED PRIOR TO INSTALLATION.

8. VERIFY ALL REQUIRED SERVICE CONNECTIONS, INCLUDING ELECTRICAL

CHARACTERISTICS, FOR ALL EQUIPMENT PRIOR TO ORDERING OR

FABRICATING MECHANICAL EQUIPMENT AND COMPONENTS.

9. THE SPACE ABOVE CEILINGS IS LIMITED. CAREFUL COORDINATION IS

REQUIRED WITH ALL TRADES BEFORE ANY PIPE, DUCT, OR EQUIPMENT IS

ORDERED &/OR INSTALLED. ANY CONFLICTS &/OR CHANGES FOUND DURING

INSTALLATION THAT RESULTS FROM THE LACK OF COORDINATION BY THE

CONTRACTORS DURING THE SHOP DRAWING PROCESS ARE THE

RESPONSIBILITY OF THE CONTRACTOR.

10. ALL MECHANICAL INFORMATION IS NOT SHOWN ON THE MECHANICAL

DRAWINGS. THE CONTRACTOR SHALL BE RESPONSIBLE FOR COORDINATION

OF ALL INFORMATION ON ALL OTHER CONSTRUCTION DOCUMENTS.

11. THE CONTRACTOR SHALL BE RESPONSIBLE TO REVIEW & USE, WHERE

APPROPRIATE, ALL THE MECHANICAL DETAILS SHOWN ON THE DRAWINGS.

DETAILS MAY OR MAY NOT BE CALLED OUT ON THE DRAWINGS WITH

SYMBOLS OR KEYED NOTES. ANY CHANGES RESULTING FROM FAILURE TO

INSTALL THE MECHANICAL SYSTEM WITHOUT USING THE INCLUDED DETAILS

SHALL BE THE RESPONSIBILITY OF THE CONTRACTOR.

12. ALL EQUIPMENT SHALL BE INDEPENDENTLY SUPPORTED FROM

STRUCTURAL MEMBERS. STRUCTURAL ELEMENTS SHOWN IN DETAILS MAY

OR MAY NOT PERTAIN TO ANY PORTION OF THE BUILDING. COORDINATE ALL

MOUNTING REQUIREMENTS WITH ARCHITECTURAL & STRUCTURAL

DRAWINGS AND SPECIFICATIONS.

13. ALL MECHANICAL COMPONENTS AND EQUIPMENT SHALL BE INSTALLED IN

ACCORDANCE WITH ALL MANUFACTURER RECOMMENDATIONS.

14. ALL SIMILAR EQUIPMENT SHALL BE OF THE SAME MANUFACTURER. AIR

INLETS & OUTLETS OF SIMILAR TYPES SHALL BE OF THE SAME

MANUFACTURER.

15. ANY PART OF THE MECHANICAL INSTALLATION THAT FAILS, IS DEEMED

UNFIT, OR BECOMES DAMAGED DURING CONSTRUCTION SHALL BE

REPLACED BY THE CONTRACTOR AT NO ADDITIONAL COST TO THE OWNER.

THE CONTRACTOR SHALL BE RESPONSIBLE FOR EQUIPMENT CHECK-IN,

SAFEKEEPING, & DAMAGE.

16. COORDINATE WITH ARCHITECTURAL REFLECTED CEILING PLAN FOR EXACT

LOCATION OF ALL CEILING DIFFUSERS & GRILLES.

17. CONTRACTOR SHALL OPERATE INSTALLED &/OR MODIFIED SYSTEMS &

DEMONSTRATE ALL ASPECTS OF THE SYSTEM TO THE ENGINEER &/OR

OWNER TO PROVE ALL ASSOCIATED SYSTEMS ARE OPERATIONAL.

18. DURING CONSTRUCTION THE CONTRACTOR SHALL MAINTAIN A SET OF AS-

BUILT REDLINED RECORD DRAWINGS AT THE PROJECT SITE. ALL CHANGES

OR DEVIATIONS IN LAYOUT, ROUTING, EQUIPMENT, COMPONENTS, &

ACCESSORIES SHALL BE RECORDED. THESE REDLINED DRAWINGS SHALL

BE GIVEN TO THE ARCHITECT / ENGINEER AFTER THE FINAL INSPECTION IN

ACCORDANCE WITH PROJECT SPECIFICATIONS.

19. ALL DUCT ELBOWS SHALL BE LONG RADIUS, UNLESS NOTED OTHERWISE.

THE ROOFTOP UNIT SHALL BE PROVIDED WITH AN INDIVIDUAL DDC CONTROLLER LOCATED AT THE UNIT.

2. OPERATION:

WARM-UP MODE OF OPERATION SHALL ALLOW THE BUILDING TO ADJUST FROM UNOCCUPIED SETPOINTS TO THE OCCUPIED SETPOINTS WITHOUT CONDITIONING THE OUTSIDE AIR. THIS WARM-UP MODE SHALL START 20 MINUTES PRIOR TO THE START OF THE OCCUPIED MODE. UNLESS ECONOMIZER COOLING IS AVAILABLE THE OUTSIDE AIR DAMPERS SHALL BE CLOSED DURING THE WARM-UP MODE.

OCCUPIED MODE OF OPERATION SHALL SEE THE SUPPLY FAN RUN CONTINUOUSLY. THE AIR HANDLING UNIT SHALL HAVE THE OUTSIDE AIR DAMPER SET TO THE MINIMUM POSITION AS NOTED IN THE AIR

HANDLING UNIT SCHEDULE.

THE FAN SHALL START AND STOP ON THE MASTER WEEKLY AND HOLIDAY SCHEDULE SET AT THE DDC SYSTEM. WHEN THE FAN IS SCHEDULED ON, ALL VAV BOXES SHALL GO TO OCCUPIED MODE. IN OTHER WORDS THE VAV BOXES SHALL HAVE THEIR OCCUPIED SCHEDULE AS A SLAVE TO THE MASTER SCHEDULE.

INTERNAL AIR HANDLING UNIT CONTROLS SHALL MODULATE TO MAINTAIN THE DESIRED SUPPLY AIR TEMPERATURE. A DISCHARGE AIR SENSOR SHALL MAINTAIN A CONSTANT DISCHARGE AIR

TEMPERATURE OF 55° F OR AS RESET BELOW (ADJUSTABLE).

WHEN ALL THE VAV BOXES ARE AT OR BELOW 75% OF THE DESIGN CFM OR ARE IN THE HEATING MODE THE SUPPLY AIR SETPOINT SHALL RESET FROM 55 F TO 58 F. WHEN THE SAME CONDITIONS NOTED ABOVE ARE MET AGAIN THE SUPPLY AIR SETPOINT SHALL BE RESET FROM 58 F TO 62 F. AS THE COOLING DEMANDS IN THE BUILDING INCREASE THE RESET SCHEDULE SHALL SEQUENCE IN REVERSE.

UNOCCUPIED MODE OF OPERATION SHALL HAVE THE FANS OFF, THE OUTSIDE AIR DAMPER SHALL BE CLOSED AND THE POWER EXHAUST FANS TURNED OFF.

IN THE UNOCCUPIED MODE THE AIR HANDLING UNIT SUPPLY FAN WILL BE STOPPED. IF SPACE TEMPERATURE WERE TO RISE ABOVE OR FALL BELOW THE UNOCCUPIED SPACE SET POINTS THE AIR HANDLING SUPPLY FAN WILL START AND HEATING OR COOLING WILL BE ENABLED TO MAINTAIN THE SPACE TEMPERATURE AT THE UNOCCUPIED SPACE TEMPERATURE SETPOINT, THE

OUTSIDE AIR DAMPERS SHALL REMAIN CLOSED.

3. STATIC PRESSURE CONTROL:

A DUCT STATIC PRESSURE DIFFERENTIAL TRANSMITTER LOCATED WHERE SHOWN ON THE PLANS, SHALL SENSE DUCT STATIC PRESSURE AND SIGNAL THE UNIT DDC CONTROLLER WHICH SHALL MODULATE THE VARIABLE FREQUENCY DRIVE (VFD) OF THE SUPPLY FAN TO MAINTAIN THE DUCT STATIC PRESSURE OF 1.0" (ADJUSTABLE, CONFIRM WITH FACILITIES

ENGINEER). THE STATIC PRESSURE SENSOR SHUT DOWN THE VFD ON HIGH PRESSURE.

THE BUILDING STATIC PRESSURE SHALL BE CONTROLLED THROUGH MODULATING POWER EXHAUST FAN TO MAINTAIN A POSITIVE ROOM STATIC PRESSURE OF 0.02" (ADJUSTABLE). THE BUILDING

STATIC PRESSURE SENSOR SHALL BE LOCATED AT THE LOBBY'S AS NOTED ON THE PLANS.

4. FAN SAFETIES:

A LOW LIMIT DUCT THERMOSTAT SHALL BE INSTALLED ON THE DISCHARGE SIDE OF THE AIR HANDLING UNIT. WHENEVER THE LOW LIMIT DUCT THERMOSTAT SENSES DISCHARGE AIR TEMPERATURES BELOW ITS 35° F SET POINT THE SUPPLY AND POWER EXHAUST FANS SHALL STOP, AND THE OUTSIDE AIR DAMPER SHALL CLOSE.

WHENEVER THE FIRE ALARM CONTROL PANEL GOES INTO ALARM ALL FANS SHALL STOP, AND THE OUTSIDE AIR DAMPER SHALL CLOSE.

THE HIGH STATIC SWITCH, LOW STATIC SWITCH, AND FREEZE STAT SHALL BE WIRED DIRECTLY INTO THE VFD TERMINAL SAFETY STRIP.
