MECHANICAL LEGEND

27. ALL EQUIPMENT REMOVED FROM THE BUILDING, DURING DEMOLITION, SHALL

BECOME THE PROPERTY OF THE CONTRACTOR AND SHALL BE REMOVED

FROM THE SITE, UNLESS OTHERWISE NOTED. THIS PROJECT REQUIRES AHU

CONTROLLERS AND VAV HOT WATER CONTROL VALVES TO BE CAREFULLY

REMOVED AND GIVEN TO THE COR. SEE DEMOLITION PLANS FOR MORE

INFORMATION.

28. EXISTING DUCT, PIPE AND EQUIPMENT SIZES NOTED ARE FOR THE

CONVENIENCE OF THE CONTRACTOR ONLY AND ARE NOT WARRANTED TO BE

CORRECT. THE CONTRACTOR SHALL FIELD VERIFY ALL EXISTING DUCT, PIPE

AND EQUIPMENT SIZES AND THEIR RESPECTIVE LOCATIONS BEFORE

PROCEEDING WITH ANY ASSOCIATED WORK.

29. PRIOR TO SUBMITTING A PROPOSAL THE CONTRACTOR IS STRONGLY

ENCOURAGED TO VISIT THE SITE AND THOROUGHLY INSPECT ALL EXISTING

CONDITIONS TO INSURE THAT THE WORK REPRESENTED ON THE DRAWINGS

CAN BE INSTALLED AS INDICATED.

30. REFER TO ELECTRICAL DRAWINGS FOR VOLTAGE AND PHASE

REQUIREMENTS FOR ALL EQUIPMENT REQUIRING AN ELECTRICAL

CONNECTION.

31. CONSTRUCTION MUST BE COMPLETED IN PHASES. REFER TO

ARCHITECTURAL DRAWINGS FOR IDENTIFICATION OF THE BUILDING AREAS

TO BE INCLUDED IN EACH PHASE. ADDITIONAL NOTES ARE PROVIDED HERE

WHEN NECESSARY TO PROVIDE SUPPLEMENTARY INSTRUCTIONS. WORK

WILL SOMETIMES BE REQUIRED IN, AND ABOVE THE CEILING OF, AREAS

OUTSIDE OF THE PHASE THAT IS CURRENTLY UNDER CONSTRUCTION. THE

CONTRACTOR IS RESPONSIBLE FOR DETERMINING THE WORK THAT MAY BE

COMPLETED IN EACH PHASE AND REGULARLY COORDINATING WITH THE

GOVERNMENT THE AREAS IN WHICH WORK MUST OCCUR.

32. INTERIOR SURFACES OF SOME EXISTING DUCTS TO BE RE-USED MUST BE

CLEANED AND RE-SEALED, AS INDICATED. SOME DUCTS ARE INSIDE OF, AND

OTHERS ARE OUTSIDE OF, THE RENOVATION AREA. MEDIUM PRESSURE

SUPPLY AND LOW PRESSURE RETURN DUCTS SERVED BY AIR HANDLING UNIT

200-AC4 MUST BE CLEANED AND RE-SEALED AS INDICATED. THIS WORK

SHALL BE COMPLETED DURING THE FIRST PHASE OF THIS PROJECT.

33. THIS PROJECT REQUIRES THE TESTING OF SOME SUPPLY AND EXHAUST

AIRFLOW RATES PRIOR TO BEGINNING CONSTRUCTION, SO THAT ACTUAL

EXISTING AIRFLOW RATES MAY BE RESTORED FOLLOWING THE WORK

DESCRIBED HEREIN. REFER TO VAV TERMINAL UNIT SCHEDULE AND SHEET

MH103 FOR ADDITIONAL INFORMATION.

34. SUPPLY AIRFLOW RATES AT VAV TERMINAL UNITS AND RETURN AIRFLOW

RATES AT GRILLES THAT ARE CONNECTED TO AHU 200-AC4 MUST BE

REBALANCED BY THIS PROJECT. EXHAUST AIRFLOW RATES AT GROUND

FLOOR GRILLES SERVED BY FANS 200-EF17, -EF-18, AND -EF29 MUST BE

REBALANCED BY THIS PROJECT. EXHAUST AIRFLOW RATES IN FIRST AND

SECOND FLOOR DUCT BRANCHES AND AT FANS 200-EF17, -EF-18, AND -EF29

MUST BE REBALANCED BY THE PROJECT FOLLOWING GROUND FLOOR DUCT

SYSTEM MODIFICATIONS AND SEALING. REFER TO VAV TERMINAL UNIT

SCHEDULE AND SHEET MH103 FOR ADDITIONAL INFORMATION.

ASSOCIATED WITH AHU 200-AC4, AS INDICATED ON VAV TERMINAL UNIT

SCHEDULE.

36. COORDINATE ALL HVAC SYSTEM OUTAGES WITH THE COR, PROVIDING

ADVANCE NOTICE OF ALL SUCH OUTAGES AS REQUIRED BY THE

VAV TERMINAL UNITS SHALL MATCH THE SIZE SCHEDULED FOR THE AIR

DEVICE NECK OR THE VAV TERMINAL UNIT INLET, UNLESS OTHERWISE

NOTED.

38. THE AIR HANDLING UNIT TO BE PROVIDED BY THE PROJECT WILL HAVE

SECTIONS LARGER THAN EXISTING BUILDING DOORS AND PASSAGEWAYS

AVAILABLE, WHICH WILL REQUIRE SECTIONS TO BE DISASSEMBLED AND

RE-ASSEMBLED ON SITE. UNITS WITH SECTIONS RE-ASSMBLED ON SITE MUST

HAVE THE FULLY ASSEMBLED UNIT CASING TESTED FOR LEAKAGE BEFORE

CONNECTING DUCTS. UNIT SHALL MEET OR EXCEED LEAKAGE CLASS 6 (CL =

6) AS BASED ON THE LEAK TESTING METHOD DESCRIBED IN THE SMACNA

HVAC AIR DUCT LEAKAGE TEST MANUAL. PROVIDE ON-SITE TEST DATA

CONFIRMING THAT UNIT'S CABINET CONSTRUCTION AND ASSEMBLY

COMPLIES WITH THESE REQUIREMENTS. UNITS FAILING INITIAL LEAKAGE

TESTS MUST BE ADJUSTED AND REPAIRED, AS NECESSARY, FOLLOWING

HVAC FLOOR PLAN - ICU GROUND FLOOR

A. REFER TO DRAWING M-001 FOR GENERAL NOTES THAT APPLY HERE.

B. DUCT CLEANING AND SEALING MUST BE PERFORMED TO THE MAXIMUM

EXTENT PRACTICAL DURING THE TWO SYSTEM OUTAGES REQUIRED TO

PLACE THE TEMPORARY AIR HANDLING UNIT IN SERVICE AND TO PLACE THE

PERMANENT UNIT IN SERVICE. ANY ADDITIONAL OUTAGES REQUIRED TO

CLEAN AND SEAL DUCTS SHALL BE SCHEDULED IN ADVANCE AND

COORDINATED WITH THE COR, AS SPECIFIED. SUCH OUTAGES SHALL HAVE

A MAXIMUM 4 HOURS DURATION, AND NO MORE THAN TWO ICU ROOMS

SHALL HAVE HVAC INTERRUPTED AT A TIME. ADDITIONAL SMALL

TEMPORARY AIR CONDITIONERS AND/OR TEMPORARY DUCT CONNECTIONS

SHALL BE PROVIDED, AS NECESSARY TO MEET THESE REQUIREMENTS.

WORK AREAS AND TEMPORARY MEASURES SHALL BE APPROVED BY THE

COR IN ADVANCE.

C. PROTECT ALL SMOKE AND FIRE/SMOKE DAMPERS, AND ASSOCIATED DUCT

SMOKE DETECTORS, FROM DAMAGE DURING CLEANING AND SEALING

DUCTS.

D. REBALANCE AIRFLOWS IN MEDIUM PRESSURE SUPPLY AIR DUCTS BETWEEN

AHU 200-AC4 AND VAV TERMINAL UNITS ASSOCIATED WITH THE AHU.

AIRFLOWS ARE INDICATED ON VAV TERMINAL UNIT SCHEDULE.

E. REBALANCE AIRFLOWS IN RETURN AIR DUCTS ASSOCIATED WITH AHU 200-

AC4. AIRFLOWS AT AIR DEVICES ARE INDICATED ON THIS DRAWING.

F. REBALANCE AIRFLOWS IN EXHAUST DUCTS ASSOCIATED WITH EXISTING

FANS 200-EF17, -EF18, AND -EF29 AS INDICATED ON THIS DRAWING. PRIOR

TO ANY OTHER WORK, THE AIRFLOWS IN THE EXISTING FIRST AND SECOND

FLOOR EXHAUST BRANCH DUCTS SHALL BE MEASURED AND VERIFIED TO

MATCH THE TABLES BELOW, AND DIFFERENCES SHALL BE REPORTED IN

WRITING. EXHAUST AIRFLOW RATES SHALL BE REBALANCED IN FIRST AND

SECOND FLOOR DUCT BRANCHES FOLLOWING COMPLETION OF ALL OTHER

WORK. EXISTING AIRFLOWS SHALL BE RESTORED DURING REBALANCING.

MANUAL VOLUME DAMPERS SHALL BE ADDED IN THE DUCT BRANCHES TO

PROVIDE A METHOD OF QUICKLY BALANCING THE AIRFLOW FOR EACH

FLOOR. FOLLOWING GROUND FLOOR DUCT MODIFICATIONS AND SEALING.

G. WORK SHOWN ON THIS DRAWING IS PART OF THE PROJECT’S FIRST PHASE.

H. FOR EXISTING VAV TERMINAL UNITS TO BE REPLACED OR RECEIVE NEW

CONTROLS, AS INDICATED IN THE VAV TERMINAL UNIT SCHEDULE, EXISTING

HOT WATER CONTROL VALVES SHALL BE CAREFULLY REMOVED AND

DELIVERED TO THE VAMC’S COR.

I. FOR EXISTING TERMINAL UNITS SCHEDULED TO HAVE CONTROLS

REPLACED, ALL INACTIVE PNEUMATIC CONTROL TUBING SHALL BE

REMOVED TO THE MAXIMUM EXTENT POSSIBLE. PERMANENTLY CAP

DEMOLISHED BRANCHES AT ACTIVE PNEUMATIC CONTROL TUBING

MAINS/BRANCHES. PROVIDE REPLACEMENT WALL TEMPERATURE SENSORS

IN EXISTING LOCATIONS.
