This is a plans and drawings document for a Building Automation System (BAS) upgrade project at the Hawthorne parking ramp facility in Minneapolis, Minnesota, issued by the City of Minneapolis Division of Traffic and Parking. The project involves upgrading the existing BAS and operator graphics with replacement of terminal-level controllers using BACnet-compliant devices at a maximum baud rate of 76,800 BPS, installation of new control devices to meet specified sequences of operation, and implementation of a new front-end operator interface and graphics based on Automated Logic Corporation equipment. The scope includes no new HVAC equipment but requires replacement of field-level controllers, installation of new sensors and actuators, removal of defunct controls, and coordination with a Test and Balance contractor to balance all VAV terminal units and minimum outdoor airflow rates. The Hawthorne ramp will remain in normal operation throughout construction, requiring the general contractor to coordinate directly with the owner to establish an acceptable construction timeline and work sequencing that minimizes disruption to ramp operations and occupants.

The project documents specify detailed control sequences for multiple systems including chilled water and heating water plants, air handling units (AHU-1 through AHU-5), VAV boxes with heating water reheat, cabinet unit heaters, unit heaters, convectors, exhaust fans, and miscellaneous controls throughout the basement, first floor, third floor, fourth floor, and seventh floor levels of the facility. All work must comply with applicable local, state, and federal codes and regulations, with the contractor responsible for obtaining all necessary permits and licenses. All sub-contractors must submit Material Safety Data Sheets to the general contractor for record-keeping and submission to the owner. The contractor is responsible for maintaining the premises free from waste materials, patching and repairing existing construction to like-new condition resulting from removals or replacements, repairing any damage to existing buildings and property during construction, maintaining egress paths at all times, and controlling dust, noise, VOCs, and vibration in the occupied environment while coordinating work schedules with building users.

AHU-2 - SEQUENCE OF OPERATION

SYSTEM OPERATES AS OCCUPIED/UNOCCUPIED ACCORDING TO ITS OPTIMAL OPERATING SCHEDULE.

OCCUPIED MODE:

· START/STOP THE SUPPLY FAN AND RETURN FAN ACCORDING TO THE OPTIMAL START SCHEDULE AND RUN CONTINUOUSLY.

UNIT SHALL RUN IN MINIMUM VENTILATION MODE.

· MINIMUM VENTILATION: OPEN THE OUTDOOR AIR DAMPER AND MODULATE OUTDOOR, RETURN AND RELIEF DAMPERS TO MAINTAIN MINIMUM DAMPER POSITION SETPOINT. REFER TO SCHEDULE AND COORDINATE DAMPER SETPOINT WITH

BALANCING CONTRACTOR.

· SUPPLY AIR TEMPERATURE RESET: THE SUPPLY AIR TEMP SETPOINT SHALL BE RESET BASED ON SPACE TEMPERATURE VS

SETPOINT 72°F (ADJ.).

ADJUSTABLE OFFSET INITIALLY SET AT +1°F. (SAT SP = 55°F THEN MAT SP = 56°F)

CONTROL VALVE SHALL MAINTAIN THE SUPPLY AIR TEMPERATURE SETPOINT.

SHALL MAINTAIN THE SUPPLY AIR TEMP SETPOINT.

· HW HEATING MODE: THE HEATING COIL CONTROL VALVE SHALL MODULATE TO MAINTAIN SUPPLY AIR TEMP SETPOINT.

PROGRAMMING SHALL BE WRITTEN TO AVOID OVERLAPPING OF HEATING AND COOLING CONTROL WHEN NOT

DEHUMIDIFYING.

UNOCCUPIED MODE:

· AHU/RTU SHALL TURN ON AND RUN IN RECIRCULATION MODE (RA DAMPER OPEN, OA/RLF DAMPERS CLOSED) WITH THE

SUPPLY & RETURN FANS ON IF THE SPACE TEMPERATURE FALLS BELOW THE AHU/RTU UNOCCUPIED HEATING SETPOINT OF 60°F (ADJ. WITH +3°F DEADBAND) OR RISES ABOVE THE AHU/RTU UNOCCUPIED COOLING SETPOINT OF 83°F (ADJ. WITH -3°F DEADBAND). THE HEATING AND CHILLED WATER COIL CONTROL VALVES SHALL MODULATE TO MAINTAIN SUPPLY AIR TEMPERATURE SET POINT AS DESCRIBED IN THE OCCUPIED SEQUENCE. THE AHU/RTU SHALL TURN OFF WHEN ALL ZONES HAVE BEEN SATISFIED AND ARE ABOVE 63°F (ADJ.) AND BELOW 80°F (ADJ.). WHEN THE UNIT IS NOT RUNNING, THE HEATING CONTROL VALVE SHALL MAINTAIN AN INTERNAL UNIT TEMPERATURE OF 50°F (ADJ.) AT THE MAT/SAT SENSORS.

ALARM MODES:

· FREEZE ALARM: UPON SENSING LOW LIMIT SUPPLY TEMPERATURE OF 35°F (ADJ.), CLOSE THE OUTDOOR AIR DAMPER, SHUT

DOWN THE FANS, AND ALARM WITH THE HEATING VALVE OPEN 100%.

· SMOKE ALARM: SMOKE DETECTOR SENSING SMOKE SHALL SHUT DOWN THE FANS, CLOSE THE OUTDOOR AIR AND EXHAUST

AIR DAMPERS,…
