About this file

Written by GovTribe AI · Dec 28, 2023

This is a solicitation for a construction project to replace an air handling unit and air cooled condenser at the Naval Undersea Warfare Center in Newport, Rhode Island. The project includes removing an existing air handling unit and installing a new central station air handling unit with direct expansion cooling coil and hot water heating coil to provide heating, cooling and ventilation for Building 1176. The electrical system serving the new mechanical equipment will also be upgraded. The solicitation is a 100% total small business set-aside with bids due on September 3, 2021 and a project completion date of 270 calendar days after award. The estimated construction value is between $500,000 and $1,000,000. The NAICS code is 238220. Interested parties must be registered in SAM and attend an optional site visit on August 5, 2021 to learn more about the project requirements.

AutoCAD SHX Text GENERAL: RUN CONDITIONS: THE AHU WILL OPERATE WITH THE FOLLOWING MODES OF OPERATION: OCCUPIED, UNOCCUPIED, ECONOMIZER, MORNING WARM-UP, AND MORNING COOL DOWN. METHOD OF CONTROL: THE SYSTEM SHALL OPERATE BASED ON THE OCCUPIED/UNOCCUPIED SCHEDULE. STATIC PRESSURE SENSOR SHALL CONTROL THE SUPPLY AND RETURN FAN OPERATION. THE RETURN FAN SHALL TRACK WITH THE SUPPLY FAN. ROOM SENSORS WILL CONTROL TEMPERATURE. COOLING SETPOINTS: OCCUPIED 75 F UNOCCUPIED 80 F HEATING SETPOINTS: OCCUPIED 70 F UNOCCUPIED 60 F OCCUPIED MODE: GENERAL: NORMALLY CLOSED OUTSIDE AIR DAMPER SHALL MODULATE OPEN TO MINIMUM POSITION AND RETURN AIR DAMPER SHALL MODULATE INVERSELY WITH THE OUTSIDE AIR DAMPER. THE SUPPLY AND RETURN FAN SHALL OPERATE CONTINUOUSLY. THE STATIC PRESSURE SHALL BE SET AT 0.75" WC(ADJUSTABLE). STATIC PRESSURE SETPOINT SHALL BE RESET BASED ON THE VAV REQUIRING THE MOST PRESSURE. THE SETPOINT SHALL RESET UNITL THE VAV DAMPER IS 90% OPEN. THE OUTSIDE AIR DAMPER SHALL MODULATE OPEN AND THE RETURN AIR AND RELIEF DAMPER SHALL TRACK THE POSITION AND MODULATE ACCORDINGLY.

AutoCAD SHX Text COOLING: WHEN THE SPACE TEMPERATURE RISES ABOVE THE DESIGN SETPOINT, START THE ASSOCIATED AIR COOLED CONDENSING UNIT TO MAINTAIN THE DESIGN SETPOINT. THE SUPPLY LEAVING AIR TEMPERATURE SHALL BE 55 DEGREES. HEATING: WHEN THE SPACE TEMPERATURE FALLS BELOW THE THE DESIGN SETPOINT, MODULATE THE HOT WATER HEATING CONTROL VALVE TO MAINTAIN THE DESIGN SETPOINT. UNOCCUPIED MODE: THE OUTSIDE AIR DAMPER SHALL REMAIN CLOSED, THE RETURN AIR DAMPER SHALL BE FULL OPEN THE SUPPLY AND RETURN AIR FAN SHALL CYCLE ON A CALL FOR HEATING OR COOLING AND THE RELIEF DAMPER SHALL BE CLOSED. WHEN THE AVERAGE OF THE VAV SPACE SENSORS RISE ABOVE THE SETPOINT AND A CALL FOR COOLING IS REQUIRED. ENERGIZE THE AIR COOLED CONDENSING UNIT TO MAINTAIN SPACE SETPOINT. WHEN THE AVERAGE OF THE SPACE SENSOR FALLS BELOW THE SPACE SETPOINT AND A CALL FOR HEATING IS REQUIRED. ENERGIZE THE SUPPLY FAN AND MODULATE THE HEATING CONTROL VALVE TO MAINTAIN SETPOINT. ONCE THE DESIGN SETPOINT IS REACHED, THE SUPPLY AND RETURN FAN SHALL BE SHUT DOWN.

AutoCAD SHX Text WHEN THE OUTSIDE DAMPER IS IN ITS MAXIMUM POSITION AND UPON A FURTHER INCREASE IN SUPPLY AIR TEMPERATURE, THE CONDENSING UNIT SHALL RUN TO MEET THE DESIGN SETPOINT. THE OUTSIDE AIR DAMPER SHALL MODULATE TO ITS MINIMUM POSITION. WHEN THE OUTSIDE DAMPER IS IN ITS MINIMUM POSITION AND UPON A FURTHER DECREASE IN SUPPLY AIR TEMPERATURE, THE HEATING COIL SHALL OPEN TO MEET THE DESIGN SETPOINT. MORNING WARM-UP: MORNING WARM UP SHALL BE INITIATED THROUGH THE DDC OCCUPANCY SCHEDULE. THE OUTSIDE AIR DAMPER AND RELIEF DAMPER SHALL BE CLOSED, AND RETURN DAMPER SHALL GO FULL OPEN. THE SUPPLY AND RETURN AIR FANS SHALL BE ENERGIZED ONCE THE RETURN DAMPER IS OPEN. THE AHU SHALL MAINTAIN SUPPLY AIR DESIGN TEMPERATURE OF 80 DEGREES UNTIL THE ROOM SETPOINT IS REACHED, THEN THE SYSTEM SHALL RETURN TO OCCUPIED MODE. MORNING COOL-DOWN: MORNING COOL-DOWN SHALL BE INITIATED THROUGHOUT THE DDC OCCUPANCY SCHEDULE. THE OUTSIDE AIR DAMPER AND RELIEF DAMPER SHALL BE CLOSED, AND RETURN DAMPER SHALL GO FULL OPEN. THE SUPPLY AND RETURN AIR FANS SHALL BE ENERGIZED ONCE THE RETURN DAMPER IS OPEN. THE AHU SHALL MAINTAIN SUPPLY AIR DESIGN TEMPERATURE OF 55 DEGREES. THE SYSTEM SHALL RETURN TO THE OCCUPIED MODE ONCE THE SETPOINT IS REACHED. SAFETIES: WHEN THE SUPPLY AIR SMOKE DETECTOR SENSES PRODUCTS OF COMBUSTION, DEACTIVATE SUPPLY AND RELIEF FANS AND FULLY CLOSE THE OUTSIDE AIR DAMPER AND SIGNAL AN ALARM TO THE DDC SYSTEM AND FIRE ALARM SYSTEM. THE INTERLOCK WITH THE SUPPLY AND RETURN FAN SHALL BE HARD WIRED AND REQUIRE A MANUAL RESET. WHEN THE SUPPLY AIR DUCT HIGH LIMIT STATIC PRESSURE SENSOR READS 5 IN. W.C. OR ABOVE(ADJUSTABLE) THE SUPPLY AND RETURN FAN SHALL BE DEACTIVATED. SIGNAL AN ALARM TO DDC. WHEN THE FREEZESTAT READS HEATING COIL DISCHARGE BELOW 40 DEGREES, OPEN THE HOT WATER CONTROL VALVES, DEACTIVATE THE SUPPLY AND RETURN AIR FANS, CLOSE THE OUTSIDE AIR AND RETURN AIR DAMPER. ANNUNCIATE THE ALARM AT THE CENTRAL DDC WORKSTATION.
