About this file

Written by GovTribe AI · Feb 4, 2025

This is a set of engineering drawings for a boiler replacement project at the U.S. Coast Guard ANT New York facility in Bayonne, Hudson County, New Jersey (Project #13920142). The drawings detail the removal of two existing oil-fired boilers and associated equipment from the MAT (Maintenance Augmentation Team) Building, and the installation of new natural gas-fired condensing boilers with supporting systems.

The drawings include site plans showing contractor staging areas, mechanical floor plans, piping diagrams, equipment schedules, and detailed specifications for the new heating plant installation. Key components include two 725 MBH natural gas boilers, circulation pumps (P-1 and P-2 rated at 45 GPM), boiler venting through modified existing openings, new gas service connections, and a building automation system for temperature control. The drawings specify requirements for temporary heat during construction, demolition of existing fuel oil systems, and modification of the mechanical room to accommodate the new gas-fired heating plant. Reference drawings from the original building construction (RD-1 through RD-8) are included to provide additional context about existing conditions and systems.

1. CENTRAL HEATING PLANT DESCRIPTION

THE PROPOSED MAINTENACE AUGMENTATION TEAM (MAT) BUILDING CENTRAL HEATING PLANT CONSISTS OF 2 CONDENSING TYPE NATURAL GAS FIRED BOILERS, ASSOCIATED BOILER CIRCULATION PUMPS, AND SYSTEM CIRCULATION PUMPS, ALL SPECIFIED FOR REPLACEMENT AS PART OF THIS PROJECT. THE CENTRAL HEATING PLANT SUPPORTS TERMINAL HEATING EQUIPMENT INCLUDING HW COILS IN AIR HANDLING UNITS, FAN COIL UNITS AND UNIT HEATERS. AHU HV-1 PROVIDES MAKE-UP AIR FOR THE AIR EXHAUSTED BY VARIOUS GENERAL EXHAUST FANS. THE HW COIL IN HV-1 IS SPECIFIED TO HAVE AN ENTERING AIR TEMPERATURE OF 14 DEGREES F. ACCORDINGLY, THE HYDRONIC HEATING SYSTEM MUST CIRCULATE WATER WITH A 30% PROPYLENE GLYCOL SOLUTION. THE HEATING HOT WATER SUPPLY TEMPERATURE IS SPECIFIED TO REMAIN AS ORIGINALLY DESIGNED WHEN THE MAT BUILDING WAS CONSTRUCTED. WITH A NOMINAL ΔT OF 20 DEGREES F, THIS LIMITS CONDENSING TO MILDER HEATING CONDITIONS. IF, IN THE FUTURE, ALL TERMINAL HEATING EQUIPMENT IS REPLACED, IT IS RECOMMENDED THAT THE EQUIPMENT BE SELECTED WITH PERFORMANCE (HIGHER ΔT, LOWER FLOW RATE) TO SUPPORT A WIDER RANGE OF

CONDENSING OPERATIONS.

2. GENERAL

PROVIDE CONTROL COMPONENTS, NOT INCLUDED INTEGRAL TO BOILER, ON A CONTROLS BACKBOARD IN THE VICINITY OF THE BOILERS AND CIRCULATION PUMPS. THIS INCLUDES CONTROL PANELS, SELECTOR SWITCHES, RUN-HOUR METERS, ALARM LIGHTS AND OTHER INDICATORS. CONTROLS BACKBOARD SHALL BE ¾” MARINE PLYWOOD, NOMINAL SIZE 48 ” X 48 ” BUT AS REQUIRED TO ACCOMMODATE ALL COMPONENTS TO BE MOUNTED THEREON, AND FASTENED TO WALL SECURELY; PAINTED BLACK, 2 COATS GLOSS FINISH.

3. SEQUENCE OF OPERATIONS

A. THE HEATING PLANT SHALL OPERATE WHENEVER THE OUTSIDE AIR TEMPERATURE IS LESS THAN 60 DEGREES F ADJUSTABLE (ADJ.).

B. OUTDOOR AIR TEMPERATURE RESET. THE HEATING PLANT SHALL OPERATE SO THAT THE HEATING HOT WATER SUPPLIED TO THE SYSTEM IS 200 DEGREES F (ADJ) AT 10 DEGREES F OUTDOOR AIR

TEMPERATURE (OAT) AND 150 DEGREES (ADJ) AT 60 DEGREES F OAT. PROVIDE AN OUTDOOR AIR SENSOR AT APPROXIMATE LOCATION INDICATED.

C. EACH BOILER AND ITS ASSOCIATED BOILER CIRCULATION PUMP SHALL BE INTERLOCKED. BOILER SHALL NOT BE ENABLED TO OPERATE UNTIL ITS ASSOCIATED CIRCULATION PUMP IS ENERGIZED AND FLOW

THROUGH THE SAME PROVEN WITH A FLOW SWITCH.

D. BOILERS SHALL OPERATE IN LEAD-LAG MODE. PROVIDE A MANUAL LEAD - LAG BOILER SELECTOR SWITCH LABELED AS SUCH, WITH POSITIONS LABELED FOR B-1 AND B-2. BASED ON THE SYSTEM HEATING

HOT WATER SUPPLY (HWS) SENSOR, THE LEAD BOILER SHALL OPERATE UNTIL THE HWS TEMPERATURE FALLS 10 DEGREES F (ADJ) BELOW THE HWS SETPOINT, WHEN THE LAG BOILER SHALL BE ENERGIZED.

PROVIDE CONTROLS TO OPTIMIZE BOILER EFFICIENCY, AND TAKE ADVANTAGE OF THE MOST EFFICIENT BOILER OPERATING EFFICIENCY UNDER PART OR FULL LOAD CONDITIONS OF THE BOILERS. BASIS - OF - DESIGN EQUIPMENT CAN BE OPERATED BASED ON SUPPLY TEMPERATURE CONTROL, GAS FLOW RATE CONTROL, OR A COMBINATION OF BOTH. DISCUSS WITH COR PRIOR TO PREPARATION OF CONTROLS SUBMITTAL, AND PROVIDE A COMPREHENSIVE CONTROLS SUBMITTAL, INTEGRATING CONTROLS THAT ARE INTEGRAL TO BOILERS PROVIDED WITH THE SEQUENCES OF OPERATIONS SPECIFIED.

INCLUDE PRODUCT SHEETS, SCHEMATIC DIAGRAMS, AND WRITTEN CONTROL SEQUENCES. UPDATE THIS DRAWING WITH THE SAME AS A RECORD DRAWING AT PROJECT CLOSEOUT.

E. PROVIDE A RUN-HOUR METER FOR EACH BOILER, MOUNTED ON THE CONTROLS BACKBOARD WITH A LABEL THAT IDENTIFIES THE ASSOCIATED BOILER. RUN-HOUR METER SHALL BE USED BY OPERATIONS

PERSONNEL TO ENSURE APPROXIMATELY EQUAL RUN-TIME FOR EACH BOILER.

F. PROVIDE EACH BOILER WITH A RED “ BOILER FAILURE ” LAMP AND ALARM LABELED AS SUCH, MOUNTED ON THE CONTROLS BACKBOARD. IF A BOILER IS COMMANDED TO OPERATE BUT FAILS TO DO SO, BOILER FAILURE LAMP FOR THE ASSOCIATED AND LABELED BOILER SHALL ILLUMINATE. LAMP SHALL REMAIN ILLUMINATED UNTIL THE CAUSE FOR THE FAILURE HAS BEEN CORRECTED, AND BOILER IS

OPERATING.

G. PROVIDE EACH BOILER WITH A NATURAL GAS METER, TO ALLOW CORRELATION OF HEATING CONSUMPTION BY EACH BOILER (AND THE HEATING PLANT) CORRELATED WITH OUTSIDE AIR TEMPERATURE.

H. HEATING HOT WATER DISTRIBUTION PUMPS SHALL OPERATE IN ONLINE - STANDBY MODE. PROVIDE A SELECTOR SWITCH TO INDEX EITHER PUMP AS THE ONLINE PUMP. OPERATION OF EACH PUMP SHALL

BE CONFIRMED BY A FLOW SWITCH IN THE DISCHARGE PIPING OF EACH PUMP. THE ONLINE PUMP SHALL OPERATE WHENEVER THE OUTSIDE AIR TEMPERATURE IS LESS THAN 60 DEGREES F (ADJ.). UPON A “ NO FLOW ” FAILURE OF THE LEAD PUMP, AN ALARM SHALL SOUND AT THE CONTROLS BACKBOARD AND THE STANDBY PUMP SHALL START.

I. PROVIDE EACH PUMP WITH A RED “ PUMP FAILURE ” LAMP AND ALARM LABELED AS SUCH, MOUNTED ON THE CONTROLS BACKBOARD. IF EITHER PUMP IS COMMANDED TO OPERATE BUT FAILS TO DO SO, PUMP FAILURE LAMP FOR THE ASSOCIATED AND LABELED PUMP SHALL ILLUMINATE. LAMP SHALL REMAIN ILLUMINATED UNTIL THE CAUSE FOR THE FAILURE HAS BEEN CORRECTED, AND BOILER IS

OPERATING.

J. PROVIDE A RUN-HOUR METER FOR EACH HW DISTRIBUTION PUMP, MOUNTED ON THE CONTROLS BACKBOARD, WITH A LABEL THAT IDENTIFIES THE ASSOCIATED PUMP. RUN-HOUR METER SHALL BE USED BY

OPERATIONS PERSONNEL TO ENSURE APPROXIMATELY EQUAL RUN-TIME FOR EACH PUMP.
