GENERAL MECHANICAL NOTES

M

230000

1. THE INTENT OF THESE NOTES AND THE MECHANICAL NOTES ON THE DRAWINGS IS TO CLARIFY THE SCOPE OF WORK AND ALERT THE CONTRACTOR OF FIELD CONDITIONS. CONTRACTOR TO VISIT SITE AND VERIFY ALL CLEARANCES BEFORE FABRICATION OF DUCTWORK AND PROVIDE ADDITIONAL OFFSET AND/OR CHANGES IN DUCT SIZES TO MEET FIELD CONDITIONS AND COORDINATE WITH ELECTRICAL, PLUMBING, AND FIRE PROTECTION SUBCONTRACTOR BEFORE ANY CONSTRUCTION WORK. NO ALLOWANCES WILL BE MADE FOR THE

CONTRACTOR'S UNFAMILIARITY WITH THE JOB SITE AND CONDITIONS.

2. PLANS SHALL NOT BE SCALED. PLANS INDICATE THE SCHEMATIC LAYOUT AND LOCATION OF THE MECHANICAL SYSTEM COMPONENTS.

UNLESS SPECIFIC DIMENSIONS ARE NOTED, THE ACTUAL LOCATION OF THESE COMPONENTS SHALL BE DETERMINED IN THE FIELD IN COORDINATION WITH THE WORK OF OTHER TRADES, THE USE OF MANUFACTURER’S SHOP DRAWINGS AND SIMILAR CERTIFIED DATA. THE ELEVATION OF EXPOSED DUCTWORK SHALL BE COORDINATED WITH THE ARCHITECT PRIOR TO ORDERING ANY DUCTWORK.

3. NO EXCLUSIONS FROM OR LIMITATIONS IN THE LANGUAGE USED IN THE CONTRACT DOCUMENTS SHALL BE INTERPRETED AS MEANING THAT THE EQUIPMENT, APPURTENANCES, AND/OR ACCESSORIES NECESSARY FOR A COMPLETE AND OPERATIONAL SYSTEM ARE NOT TO

BE PROVIDED AS REQUIRED.

A. THE CONTRACTOR SHALL HAVE A COMPLETE SET OF THE CONTRACT DOCUMENTS. THE SEPARATE DIVISIONAL DRAWINGS AND

SPECIFICATIONS DO NOT RELIEVE THE CONTRACTOR FROM THE RESPONSIBILITY TO PROVIDE THE WORK WHICH IS INDICATED ON ANY OF THE DRAWINGS OR DIVISION OF THE SPECIFICATIONS. REVIEW AND COORDINATE THE SCOPE OF WORK TO ASSURE A COMPLETE AND FUNCTIONAL SYSTEM IS INSTALLED. SHOP DRAWINGS OF ALL EQUIPMENT AND MATERIALS FOR REVIEW.

4. SUBMIT SHOP DRAWINGS OF ALL EQUIPMENT AND MATERIALS FOR REVIEW. WHERE MANUFACTURERS ARE LISTED IN THE PROJECT MANUAL, ONE OF THOSE MANUFACTURERS SHALL BE PROVIDED UNLESS A REQUEST FOR SUBSTITUTION HAS BEEN SUBMITTED PRIOR TO BID AND THE MANUFACTURER SUBSEQUENTLY IS LISTED AS AN ACCEPTABLE MANUFACTURER IN AN ADDENDUM. PARTIAL SUBMITTALS WILL NOT BE ACCEPTED FOR REVIEW AND APPROVAL. INSTALL AND TEST ALL EQUIPMENT AND MATERIALS IN ACCORDANCE WITH THE MANUFACTURER’S INSTRUCTIONS AND RECOMMENDATIONS. FOR ALL EQUIPMENT, WHICH HAS BEEN SCHEDULED DIRECTLY ON THE DRAWINGS, PROVIDE WITHIN THE SUBMITTAL, A PERFORMANCE SCHEDULE FOR THE PROPOSED EQUIPMENT IN THE EXACT SAME FORMAT AS INCLUDED ON THE CONTRACT DOCUMENTS. FAILURE TO PROVIDE REQUIRED PERFORMANCE SCHEDULE WILL RESULT IN REJECTION OF THE ENTIRE SUBMITTAL.

SUBMIT DRAWINGS AND CUT SHEETS FOR ALL PRODUCTS ALL AT ONE TIME. INDEX ALL ITEMS TO THE PROJECT MANUAL OR DRAWINGS AS APPLICABLE. SHOP DRAWINGS THAT DEVIATE FROM THE REQUIREMENTS OF THE CONTRACT DOCUMENTS SHALL LIST ALL DIFFERENCES IN A COVER LETTER ATTACHED TO FRONT OF THE SUBMITTAL. ANY UNLISTED DEVIATIONS FOUND DURING REVIEW WILL RESULT IN THE REJECTION OF THE ENTIRE SUBMITTAL. FOR ITEMS REVIEWED AND MARKED "REJECTED" OR "REVISE AND RESUBMIT”, ONLY ONE ADDITIONAL SUBMITTAL WILL BE REVIEWED TO VERIFY PRODUCT COMPLIANCE WITH THE CONTRACT DOCUMENTS. SHOULD FURTHER SUBMITTALS BE REQUIRED FOR THE DESIGN PROFESSIONAL TO VERIFY THE SUBMITTAL WITH THE REQUIREMENTS OF THE CONTRACT DOCUMENTS, THE HOURLY RATE OF $150.00 PLUS EXPENSES WILL BE BILLED TO THE CONTRACTOR FOR THE PROFESSIONAL(S) TIME IS SPENT ON THE REVIEW.

5. ALL PIPING AND/OR DUCTWORK MUST BE INSTALLED 6” AWAY FROM ANY FIRE RATED WALL.

6. ALL PIPE PENETRATIONS SHALL BE SEALED USING APPROVED UL DETAILS. ALL FIRE DAMPERS SHALL BE DYNAMIC TYPE.

7. PROVIDE ADDITIONAL DUCTWORK AND PIPING SUPPORTS ON BOTH SIDES AND WITHIN 18" OF FIRE RATED WALLS. DUCTWORK OR PIPING

SHALL NOT BE SUPPORTED FROM ANY FIRE RATED WALL.

8. ROOF MOUNTED EQUIPMENT SHALL BE SECURED TO THE CURB AND THE CURBS SHALL BE SECURED TO THE STRUCTURE AS DETAILED BY THE

SIGNS DESIGNATED FOR INSTALLATION ON THE OUTSIDE, IN OPEN AREAS, OR LOCATED IN A PROTECTED AREA THAT IS SUBJECT TO DIRECT SUNLIGHT, SHALL BE UV RATED, DESIGNATED AND MANUFACTURED TO BE EXPOSED TO THE ELEMENTS. SUBMITTAL DATA INDICATING THE ABOVE WILL BE REQUIRED. LABELS SHALL ALSO INCLUDE THE ROOM NUMBER, CORRESPONDING AIR HANDLER LOCATION OR AREA SERVED TO ASSIST IN THE DETERMINATION OF THE SERVICE LOCATION OF SAID EQUIPMENT. PROVIDE ADDITIONAL NAMEPLATE ON CEILING GRID DIRECTLY BELOW EQUIPMENT CONCEALED ABOVE CEILINGS TO AID IN LOCATING THE UNIT. NAMEPLATE DESIGNATION SHALL CONSIST OF UNIT

NUMBER.

11. EQUIPMENT SHALL BE MANUFACTURED AND/OR COATED AS REQUIRED FOR INSTALLATION IN A SEA COAST ENVIRONMENT.

12. ALL WALL MOUNTED TEMPERATURE AND HUMIDITY SENSORS SHALL BE INSTALLED AT A CENTER LINE ELEVATION OF 4’—0” ABOVE FINISHED

UPON PROOF OF FLOW THROUGH SECONDARY LOOP AS CONFIRMED BY NEW FLOW SENSOR THE CONTROLLER SHALL ENABLE B-1, OPEN IT'S MOTORIZED ISOLATION VALVE, AND ENERGIZE INTERNAL BOILER PUMP. BOILER SHALL MODULATE FIRING AND FLOW TO MAINTAIN DISCHARGE SET POINT OF 180°F(ADJ.) AS SENSED BY THE BOILER HWS SENSOR.

UPON A DROP IN HWR RETURN TEMPERATURE AS SENSED BY HW LOOP HWR SENSOR BELOW 140°F(ADJ.) THE CONTROLLER SHALL ENABLE BOILER B-2. BOILER SHALL MODULATE FIRING AND FLOW TO MAINTAIN DISCHARGE SET POINT OF 180°F(ADJ.) AS SENSED BY THE HW LOOP HWS SENSOR.

DISABLED MODE:

WHEN OUTSIDE AIR TEMP. IS ABOVE 55°F(ADJ.) THE HEATING PLANT SHALL BE LOCKED OUT. REHEAT HEATING HOT WATER PROVIDED BY EXISTING HEAT RECOVERY CHILLER (CH-4).

EXISTING CHILLER SEQUENCES TO REMAIN.

HOT WATER PUMP ROTATION:

HOT WATER PUMPS HHWP-1 AND HHWP-2 ARE REDUNDANT PUMPS AND SHALL ONLY OPERATE ONE AT A TIME. THE ACTIVE PUMP SHALL BE ROTATED WEEKLY VIA USER ADJUSTABLE

SCHEDULE. INACTIVE PUMP SHALL BE LOCKED OUT THROUGH THE CONTROLS.

GAS LEAK DETECTION:

SHALL BE PROVIDED VIA A SELF CONTAINED PROGRAMMABLE CONTROLLER WITH CARBON MONOXIDE (C0) AND NATURAL GAS METHANE (CH4) GAS DETECTORS WITH EITHER 24VAC OR 120VAC OUTLET SIGNAL TO AUTOMATIC GAS SHUT-OFF VALVE AND FIRE ALARM TIE-IN, AND 0.5 A BMS RELAY FOR ALARM. PROVIDE DRY CONTACT RELAYS FROM NEW GAS
