About this file
This document is a comprehensive set of architectural and engineering design drawings for the HVAC replacement project at the Child Development Center (Building 1994) at Hanscom Air Force Base. The project involves replacing the existing HVAC systems, including multiple air conditioning units (AC-1, AC-2, AC-3), an air handling unit (AHU-1), exhaust fans (EF-1, EF-2), and associated ductwork and controls. The design specifications include detailed mechanical, electrical, and structural plans for installing new HVAC equipment with specific requirements such as concrete equipment pads, security fencing, duct routing, and integration with the existing building control systems. The drawings outline precise installation details, equipment specifications, and sequence of operations, with a focus on maintaining building functionality during the renovation and ensuring proper system performance, including occupancy mode controls, temperature management, and safety protocols.

NOT INDICATED TO BE REUSED OR TURNED OVER TO THE OWNER SHALL BE DISPOSED OF
BY THE CONTRACTOR.
12. THE MECHANICAL CONTRACTOR SHALL PROVIDE ALL CUTTING AND PATCHING NECESSARY
TO REPAIR ANY DAMAGE CAUSED BY CONSTRUCTION ACTIVITIES UNDER HIS/HER
CONTRACT. THIS WORK INCLUDES AREAS OUTSIDE ANY LIMITS OF CONSTRUCTION LINES
INDICATED ON THE DRAWINGS.
13. RUBBISH AND DEBRIS SHALL BE REMOVED FROM THE WORK AREAS DAILY, UNLESS
OTHERWISE DIRECTED, TO AVOID ACCUMULATION AT THE DEMOLITION SITE. MATERIALS
THAT CANNOT BE REMOVED DAILY SHALL BE STORED IN AREAS SPECIFIED.
DEMOLITION KEYED NOTES:
DEMOLISH AND REMOVE AHU-1 UNIT. DEMOLITION SHALL INCLUDE ALL GAUGES,
INSTRUMENTATION, CONTROLS, SUPPORTS, ELECTRICAL AND MECHANICAL
CONNECTIONS, AND ALL APPURTENANCES.
RETAIN THE SUPPLY AND RETURN DUCTWORK AS INDICATED. PRESERVE THE
CONNECTIONS SUCH THAT THESE CAN BE REUSED TO CONNECT TO THE NEW UNIT.
DISCONNECT ALL HOT WATER SUPPLY AND RETURN PIPING TO THE UNIT. RETAIN THE
PIPING FOR CONNECTION TO THE NEW UNIT.
DISCONNECT AND DEMOLISH THE OUTDOOR CONDENSING UNIT, HOUSEKEEPING PAD,
AND ALL REFRIGERANT PIPING TO THE EXISTING AHU-1. DEMOLITION SHALL INCLUDE
ALL REFRIGERANT PIPING, SUPPORTS, HANGERS, ALL APPURTENANCES INCLUDING
THE CONDENSING UNIT.
DEMOLISH AND REMOVE THE OUTSIDE AIR INTAKE AS SHOWN. EXTEND THE LOUVER
BLOCKAGE TO INCLUDE THE OPENING.

GENERAL NOTES:
ALL INFORMATION AND WORK SHOWN AS EXISTING WAS TAKEN FROM FIELD VISITS BY
THE ENGINEER AND FROM OWNER PROVIDED PAST CONSTRUCTION DOCUMENTS.
EQUIPMENT AND DUCTWORK HAVE BEEN SHOWN IN AN APPROXIMATE WAY.
CONSEQUENTLY, THE INFO IS APPROXIMATE AT BEST.
ALL WORK SHALL BE PERFORMED WITH "DUE CARE AND DILIGENCE" SO AS TO PREVENT
THE UNNECESSARY DESTRUCTION AND OR DAMAGE TO SYSTEMS THAT SHALL REMAIN
IN OPERATION DURING THE PERFORMANCE OF THIS WORK.
DETERMINE THE EXACT LOCATIONS OF ALL EXISTING EQUIPMENT, DEVICES AND WIRING
BEFORE COMMENCING WORK. NOTIFY ENGINEER WITH ANY QUESTIONS.
THE CDC FACILITY AND ALL ADJACENT SPACES TO THE LIMIT OF WORK NEEDS TO
REMAIN OPERATIONAL AT ALL TIMES DURING THE DEMOLITION AND CONSTRUCTION
ACTIVITIES. ISOLATE THE SUPPLY AND RETURN AIR BRANCH DUCTWORK TO ENSURE
THAT NO AIR IS TRANSFERRED OUT OF THE LIMIT OF WORK AREA. PROVIDE
TEMPORARY VENTILATION IF REQUIRED.
CONTRACTOR SHALL PROVIDE A CONSTRUCTION SCHEDULE AND CONSTRUCTION
PHASING PLAN FOR GOVERNMENT APPROVAL PER THE BASIC MACC CONTRACT PRIOR
TO COMMENCING WORK. SERVICE TO MORE THAN ONE ZONE SHALL NOT BE REMOVED
FROM ACTIVE SERVICE SIMULTANEOUSLY DURING PHASED CONSTRUCTION. HVAC
SERVICES SHALL NOT BE INTERRUPTED WITHOUT PRIOR APPROVAL OF GOVERNMENT
AND TEMPORARY SERVICES SHALL BE PROVIDED FOR OUTAGES DURING WORKING
HOURS AND LONGER THAN 8 HOURS.
INSTALL UNITS IN A MANNER TO MEET THE MANUFACTURER'S RECOMMENDED
CLEARANCES AS REQUIRED.
INSTALL AN EMERGENCY HVAC SHUTOFF/POWER (EPO) PUSH BUTTON AT THE MAIN
FACILITY ENTRANCE. COORDINATE LOCATION OF EPO WITH THE GOVERNMENT.

SEQUENCE OF OPERATION - AC-1, AC-2, & AC-3
A. EACH AC UNIT SHALL OPERATE TO SERVE THE SPACES WITHIN
BUILDING 1994.
B. THE HVAC SYSTEM SHALL BE PROVIDED WITH BACNET
COMPATIBLE FACTORY CONTROLS AND PROGRAMMED TO
OPERATE THE HVAC SYSTEM IN THE APPROPRIATE MODE OF
OPERATION.
C. THE EXISTING FACILITY DDC CONTROL SYSTEM, ENERGY
MANAGEMENT CONTROL SYSTEM (EMCS), AND BASE WIDE
BUILDING CONTROLS, UTILITY MONITORING AND CONTROL
SYSTEM (UMCS), AT HANSCOM AFB ARE JCI METASYS USING
BACNET MS-TP PROTOCOL. THE MASTER CONTROL PANEL IS
LOCATED IN BUILDING 1810. ALL NEW CONTROLS SHALL BE
FURNISHED BY JCI. THE CONTRACTOR SHALL PROVIDE CONTROL
SYSTEMS USING BACNET MS-TP PROTOCOL AND SHALL
INTEGRATE THE NEW SYSTEM CONTROLS WITH THE EXITING JCI
METASYS SYSTEM. DESIGN AND PROVIDE GRAPHICS,
PROGRAMMING, SYSTEM INSTRUMENTATION DIAGRAM,
SEQUENCE OF OPERATIONS, SCHEMATICS, POINT LIST, LABEL,
AND DESCRIPTIONS, ONE-LINE DIAGRAM OF THE BUILDING
CONTROLS IDENTIFYING EXISTING AND NEW COMPONENTS AND
DEVICES.
D. THE HVAC SYSTEM SHALL BE CONTROLLED BY THE DDC SYSTEM.
THE DDC CONTROLLER'S MAIN FUNCTION IS TO OPERATE THE
HVAC SYSTEM IN THE APPROPRIATE MODE OF OPERATION. THE
HVAC DDC CONTROL SYSTEM SHALL BE CAPABLE OF AUTOMATIC
SYSTEM STARTUP BASED ON OPTIMAL START, NIGHT SETUP,
TIME SCHEDULE, RESTART FOLLOWING A FIRE ALARM, OR
RESTART FOLLOWING A POWER FAILURE.
E. THE BUILDING IS SERVED BY EXISTING TERMINAL UNITS (FPTU)
WITH HOT WATER COILS. THE FPTU'S PROVIDE BUILDING
HEATING AND ARE INTEGRATED WITH THE EXISTING DDC
SYSTEM. ON A CALL FOR SPACE HEATING THE HOT WATER
VALVES ON THE TERMINAL UNITS OPEN TO PROVIDE SPACE
HEATING. THE FUNCTION OF THE NEW AC UNITS WILL BE
INTEGRATED WITH THAT OF THE EXISTING TERMINAL UNITS.
F. THE EXISTING BUILDING HAS EXISTING DUCT PRESSURE
SENSORS (P-2) LOCATED AT COLUMN LINE 5-B (AC-1), COLUMN
LINE 14-E (AC-2), AND ROOM 160 (AC-3). THESE DUCT PRESSURE
SENSORS SHALL BE REPLACED WITH NEW SENSORS AND SHALL
BE INTEGRATED INTO THE DESIGN OF THE DDC SYSTEM.
G. THE EXISTING BUILDING HAS THREE BUILDING PRESSURIZATION
SENSORS SHALL REMAIN AND BE INTEGRATED INTO THE DDC
SYSTEM. THESE BUILDING PRESSURE SENSORS SHALL HAVE NO
OPERATIONAL FUNCTION.
OCCUPANCY MODE:
A. THE OCCUPANCY MODE SHALL BE COMMUNICATED OR
HARDWIRED TO THE CONTROLLER VIA A BINARY INPUT. VALID
OCCUPANCY MODES FOR THE UNIT SHALL BE:
OCCUPIED MODE - COOLING:
A. OCCUPIED ROOM COOLING SET POINT FOR SUMMER MONTHS
SHALL BE 74°F (ADJ).
B. IN OCCUPIED MODE, EACH AC UNIT SHALL OPERATE
CONTINUOUSLY TO SATISFY THE TEMPERATURE AND HUMIDITY
SETPOINTS. VFD'S WILL MODULATE SUPPLY FAN AIRFLOW BASED
ON DUCT STATIC PRESSURE TO MEET TEMPERATURE
REQUIREMENTS IN DESIGNATED ZONES.
C. UPON START-UP, THE CONTROL SYSTEM WILL OPEN THE
OUTSIDE AIR DAMPER TO ALLOW THE REQUIRED OUTSIDE AIR
FLOW INTO THE SPACE. THE RELIEF AIR DAMPER SHALL
MODULATE IN SYNC WITH THE OUTSIDE AIR DAMPER TO
MAINTAIN MINIMUM DUCT STATIC PRESSURE (0.6” WG ADJ).
D. WHEN THE SPACE TEMPERATURE IS ABOVE 74°F (ADJ), THE VFD'S
WILL MODULATE SUPPLY FAN AIRFLOW BASED ON DUCT STATIC
PRESSURE TO MEET TEMPERATURE REQUIREMENTS IN
DESIGNATED ZONES. THE RELIEF AIR DAMPER SHALL MODULATE
IN SYNC WITH THE OUTSIDE AIR DAMPER TO MAINTAIN MINIMUM
DUCT STATIC PRESSURE (0.6” WG ADJ).
E. IN COOLING MODE, THE SYSTEM SHALL OPERATE TO MAINTAIN
THE HUMIDITY LEVEL AT OR BELOW 50%. IF A ZONE'S SPACE
TEMPERATURE IS SATISFIED BUT HUMIDITY IS ABOVE 50%, THE
RESPECTIVE ZONE'S INTERIOR TERMINAL UNITS, SUCH AS FPTU'S
HOT WATER REHEAT COIL SHALL OPERATE TO PROVIDE
DEHUMIDIFICATION FUNCTION. THE RESPECTIVE FPTU'S REHEAT
COIL SHALL REMAIN IN OPERATION UNTIL THE SPACE HUMIDITY IS
AT 50% OR BELOW.
F. DURING DEHUMIDIFICATION MODE, EACH AC UNIT SHALL
CONTINUOUSLY OPERATE TO REMOVE HUMIDITY FROM THE
SUPPLY AIR.
G. THE ECONOMIZER SHALL BE ENABLED WHENEVER OUTSIDE AIR
TEMPERATURE IS LESS THAN 55 F DB (ADJ), THE OUTSIDE AIR
HUMIDITY IS LESS THAN 22 BTU/LB (ADJ), THE OUTSIDE AIR
TEMPERATURE IS LESS…
