HVAC

Executive Summary:

The primary heating and air conditioning equipment within the Medford Police & Fire Station Building have deteriorated beyond normal maintenance and upkeep. It appears that the heating system presently installed is original to the building with the exception of several roof top units. Overall the system is lacking ventilation air and thermal comfort creating hot and cold spots throughout the building. We recommend a complete upgrade of the entire heating system and control system to achieve higher system efficiencies, reduce energy consumption, provide code required ventilation and provide quality temperature control.

Heating Plant:

There are two cast iron sectional Weil McLain boilers which are original to the building; they generate hot water as the main heat source for the entire building. The boiler capacity is unknown at this time. Due to the corrosion occurring on the jacket of the boilers, it would appear that the cast iron sections are leaking towards the base of the sections which would indicate thermal shock has occurred. It is obvious that they have reached the end of their serviceable life. The boilers operate on number two fuel oil which is stored in an outdoor underground storage tank. The storage tank oil level is monitored through the use of level gauge found within the boiler room which is in- operable. The burners utilized are of the Power Flame manufacturer and are designed for fuel oil only and have a capacity of 29.0 gallons per hour. The boiler generates hot water which is distributed throughout the building by two base mounted end suction pumps and travels through what appears to be Schedule 40 black steel pipe. Some of the piping system is insulated with what appears to be fiberglass insulation and asbestos elbows, this should be verified. All of the piping insulation in the building appears to be deteriorating and in some cases falling off. The overall condition of the hot water piping system appears to be in need of replacement however, several test cuts should be completed to visually inspect the inner pipe to determine its condition. Combustion gases generated from the boilers exhaust into a black steel breeching system which is wrapped with what appears to be a canvas jacket. The combined breeching system exits the building through an existing masonry chimney. The breeching system is provided with a barometric damper for stack pressure neutralization. Combustion air for the boilers is provided through one wall mounted louver. The louver is not equipped with a damper and appears to be undersized and not code compliant.

Temperature Controls:

Automatic temperature controls for majority of the building is provided by Cleveland pneumatic control system. Compressed air is provided through a single air storage tank with dual tank mounted compressors and motors. This system provides individual heating controls and is capable of maintaining day/night set points. There was no refrigerant air dryer system associated with the air compressor system. The control system appears to be malfunctioning and the controllability of the system is less then desirable. Each roof top unit is associated with one centrally located electronic thermostat which is programmable, however, due to the location of the thermostats hot and cold spots are experienced throughout. We would recommend removing the pneumatic system and stand alone electronic system and replacing it with a direct digital control system throughout.

Basement:

The basement level is equipped with an indoor hot water air handling unit which provides heating and ventilation air to the locker room area. Tempered air is distributed throughout the space utilizing a galvanized sheet metal ductwork system. Air is returned back to the unit through a low wall mounted grille, it is unknown if outside air is actually being delivered to the space as the units components are antiquated and have reached the end of its serviceable life. General exhaust is located in the shower area which is adjacent to the locker rooms. Exhaust air enters the ceiling mounted grilles and travels through a galvanized sheet metal ductwork system to a centrifugal exhaust fan mounted high within the mechanical room, from there the air exits the building at a wall mounted louver also located within the mechanical room.

HVAC

Executive Summary:

The primary heating and air conditioning equipment within the Medford Police and Fire Training/Garage Building has deteriorated beyond normal maintenance and upkeep. It appears that the heating system presently installed is original to the building with the exception of the lower level rooftop unit. Overall the system is lacking ventilation and exhaust air and thermal comfort, creating hot and cold spots throughout the building. We recommend a complete upgrade of the entire heating system and control system to achieve higher system efficiencies, reduce energy consumption, provide code required ventilation and provide quality temperature control.

Temperature Controls:

Automatic temperature controls for the building is complete with standalone electronic thermostats. These standalone thermostats are tied directly into each unit and are original to the building. These thermostats were provided by the equipment manufacturer. The garage bay unit heaters have typical dial type thermostats while the rooftop unit associated with the garage bay office area is not a programmable type and does not offer any additional options other than temperature control and unit activation. The rooftop units associated with the building office area are programmable style and allow day/night setback control as well as unit activation. Each rooftop unit is associated with one centrally located electronic thermostat however, due to the location of the thermostats, hot and cold spots are experienced throughout. The control system appears to be malfunctioning and the controllability of the system is less then desirable due to the functionality of the rooftop units. We would recommend removing the stand alone electronic system and replacing it with a direct digital control system throughout.

Office Building Lower Level :

The office building lower level is tempered with the use of an outdoor roof-mounted air handling unit which is equipped with a gas-fired furnace for heating and direct expansion refrigerant system for cooling. Heating and air conditioning is distributed throughout the lower level spaces utilizing a galvanized sheet metal ductwork system. Air is returned back to the unit through ceiling-mounted return grilles. It does not appear that outside air is actually being delivered to the spaces as the unit did not have any intake or exhaust dampers installed. Due to the black soot on the diffusers and the ceiling tiles, it would confirm that the internal components of the unit are relatively dirty as well as the ductwork. The rooftop associated with this level is not original to the building however, it does not appear to have been installed within the last ten years. Since this unit does not have an outside air intake, no outside air is being delivered therefore this system is not code compliant and should be replaced with a code compliant system. An exhaust air system is present in the bathrooms. Air enters the ceiling-mounted grilles and travels through a galvanized sheet metal ductwork system to a roof-mounted exhaust fan. The exhaust fan appears to be in fair condition however, the bearings or motor shaft appeared misaligned due to the noise being generated by the fan. We would recommend replacing the exhaust fan based on these findings.

All the plumbing fixtures are in need of replacement. All original fixtures are recommended to be replaced new fixtures. All new fixtures are to be water conservation type.

Fixture counts and quantities are to be verified and installed to meet the current Plumbing Code requirements.

All fixture locations that do not meet the current Access Code requirements for accessible plumbing fixtures are to be provided. All new faucets and fixtures are to be water conservation type.

In general, all the drainage and vent piping systems may be reused. Should the decision be made to reuse the existing piping systems the piping needs to be tested to verify reuse. Reuse will also be based on the piping systems being adequately sized for the intended new use. The existing sanitary and roof drainage systems should also be videoed to verify the condition of the piping.

Properly cap and make safe all unused plumbing connections.

All new valves are to be provided on any existing water piping to remain.

Install any new fixtures to meet program requirements.

We recommend replacement of the existing units with high-efficiency type gas-fired domestic water heater.

Relocate gas service and meters to outside the building. Provide new piping, valves to suit new program requirements.

Abate all asbestos on existing piping, fittings, and storage tank.

Where existing fixtures are connected to the existing sewerage ejectors, additional electrical costs occur due to frequent pumping with the use of non-water conserving type fixtures.

Existing fixtures and trim are not water conserving type fixtures. Although, most fixtures are operable they are showing signs of wear and deterioration. Fixtures are over 50 years old and have reached their projected useful life.

Recommendations:

Existing fixtures and trim are not water conserving type fixtures.

Although most fixtures are still operable they are showing signs of wear and deterioration.

All the plumbing fixtures are in need of replacement. All original fixtures are recommended to be replaced new fixtures. All new fixtures are to be water conservation type.

Fixture counts and quantities are to be verified and installed to meet the current Plumbing Code requirements assembly use.

All fixture locations that do not meet the current Access Code requirements for accessible plumbing fixtures are to be provided. All new faucets and fixtures are to be water conservation type.

In general, all the drainage and vent piping systems may be reused. Should the decision be made to reuse the existing piping systems the piping needs to be tested to verify reuse. Reuse will also be based on the piping systems being adequately sized for the intended new use. The existing sanitary, garage waste and roof drainage systems should also be videoed to verify the condition of the piping.

Properly cap and make safe all unused plumbing connections.

All new valves should be provided on any existing water, compressed air, and fluid piping to remain.

Install any new fixtures to meet program requirements.

FIRE PROTECTION Executive Summary: The Medford Police Training and Fire Equipment Garage was originally constructed in 1978. Minor renovation projects have occurred over the years. The building is predominantly a two story building. A portion of the building has a three story fire training stairwell attached to the building. Presently, the building is protected with a partial wet sprinkler system for the garage portion of the building only. The three story fire training stair tower contains a sprinkler and standpipe training systems. Systems for this area are drained when not being used for training. A fire department connection used for training is located on this portion of the building. Fire Protection System: The building is served by a 6 inch fire water service entering the mechanical/storage room at the rear of the building from Union Street. There is no back flow prevention device on the incoming fire service. The system is a wet system with a 4 inch alarm valve with water motor gong. The incoming pressure is approximately 70 psi based on pressure gauge on the inlet of the alarm valve. The fire department connection for the system is located outside the mechanical/storage room at the rear of the building on Union Street. Valves on the system are chained and locked and are not electrically supervised. The existing sprinkler piping is steel with flanged and threaded joints.

Building Fire Service


Medford Police & Fire Station Academy Building Medford, MA Fire Protection Existing Conditions Systems Report J#640 022 00.00 L#39164/Page 2/November 12, 2012 Recommendations:

Massachusetts Code requires that any new building or substantially renovated building of this type of use, 12,000 square feet or more, must be sprinklered. This building will meet those thresholds and will need to have sprinklers installed based on the extent of renovation.

Any concealed combustible spaces will require sprinklers.

In general, the existing sprinkler piping systems may be reused. Should the decision be made to reuse the existing piping systems the piping needs to be tested to verify reuse. Reuse will also be based on the piping systems being adequately sized for the intended new use.

All new and existing valves to remain are to be electrically supervised.

Install any new wet sprinkler system in all areas to meet program requirements.

ELECTRICAL Executive Summary: In general, the electrical systems range from original vintage to more recent upgrades such as the service equipment. The electrical service is adequate in capacity and voltage characteristics. It is our recommendation, taking into consideration the age and general condition of the existing equipment, that most systems be replaced with new energy efficient code compliant systems, such as fire alarm, emergency lighting, interior lighting, exterior lighting, generator, power distribution equipment, and panelboards. Electrical Distribution System: There is one service present at the facility. The service is rated at 800A, 120/208V, 3, 4W and has adequate capacity for the building with its present needs. The existing service equipment is manufactured by Seimens and is relatively new. The site is on one secondary meter located in the main electric room. The service is overhead to the building from utility pole mounted transformers.

Overhead Service Meter There are electrical sub-panels located throughout the facility. The panels are circuit breaker type and are original to the building. The panels are manufactured by Federal Pacific and are in poor condition. Federal Pacific breakers have a history of failing and not providing the rated over current protection as required by code. Some panels have breakers that are missing with no blank covers and spare breakers are not readily available.

Toilet Room Stairs Sleeping quarters consists of recessed 2 ft. x 4 ft. fluorescent fixtures. Corridors in the upper level are surface mounted drum fluorescent fixtures. The Boiler room has industrial fluorescent fixtures with T12 lamps and some with T8 lamps. Booking has surface 1 ft. x 4 ft. wraparound surface fluorescent fixtures.




Boiler Room Booking Emergency Lighting System: There is an exterior emergency generator present. The generator appears to be original to the building. The generator is rated at 275 kW, 120/208 V, 3, 4W and is manufactured by Kohler with a diesel base tank. There is one transfer switch which covers the entire building. The transfer switch appears relatively new and is in good condition and is manufactured by ASCO.

Exterior Generator Transfer Switch




Exit signs appear to be fluorescent type, are in poor condition, and are not lit. Most areas are lacking exit signs which are required to meet current codes.

Exit Sign Site Lighting System: The lighting at the site consists of perimeter lighting which lights the area walkways from the exterior walls of the building. They are original to the building and appear to provide adequate lighting.

Exterior Perimeter Lighting Exterior Entrance Lighting Fire Alarm System: The fire alarm panel is manufactured by Notifier and is a non-addressable system. The system is not ADA compliant due to the horn/strobe ratings. ADA requires strobes to have a specific candela and decibel rating for a specific room or space configuration. Transmission is via a local master box.




Master Box Fire Alarm Control Panel

The coverage of fire alarm devices is lacking in most areas. Heat detectors and smoke detectors are not present in most rooms. The Massachusetts State Building Code requires all rooms or spaces to be provided with automatic alarm devices in non-sprinklered buildings. The spacing of devices must comply with NFPA 72.

Smoke Detector Heat Detector

Pull Station and Horn/Strobe




Data/Telephone/Security System: There is a telephone system present which is used throughout the stations. The telephone service is provided overhead from a utility pole into the electrical shop. Service runs to the recently renovated 911Dispatch Center on the second floor. 911 Dispatch Center: The 911 Dispatch Center consists of recessed fluorescent downlights, 2 ft. x 2 ft. fluorescent fixtures and edge-lit exit signs. The panelboard is new and receptacles are provided throughout the space. Smoke detectors, manual pull stations, and horn/strobe units are present. All equipment is relatively new and in good condition with the exception of the non-addressable fire alarm equipment and devices.

Recommendations Electrical Distribution System: The existing service is relatively new and sufficient for the present needs of the station. It provides some future capacity. Panelboards throughout the facility are in poor condition as described on Page 1 of this report. The panelboards need to be replaced. Branch Circuit: Receptacles throughout the facility are not sufficient for the present needs. Additional outlets should be provided in the sleeping quarters and other areas throughout the building to eliminate the need for extension cords. This would not require an increase to the existing electrical service. Interior Lighting: The existing lighting is not the most energy efficient type. Additional energy savings would be achieved by replacing the lighting system and controls. Emergency Lighting: The existing generator is sufficiently sized to provide emergency power to the entire building at the present time including some additional future outlets. The automatic transfer switch is in good condition. The generator is original to the building, is in fair condition and is at the end of its useful life. The existing generator should be replaced with a new exterior unit. Additional emergency lighting needs to be provided throughout the building. A second transfer switch should be provided to include life safety loads only. Site Lighting: The existing exterior lighting appears to provide sufficient coverage. However, existing fixtures are original to the building and are not the latest energy efficient type. Additional energy savings can be achieved with newer fixtures and control. Fire Alarm System: Existing fire alarm system does not meet todays code requirements for full coverage and strobe levels. A new addressable system should be provided with new addressable devices and ADA Horn/Strobe units meeting current code requirements. Data/Telephone/Security System: Existing system appears to provide adequate devices to accommodate current needs. Additional devices should be provided as the need arrives.

ELECTRICAL Executive Summary:

The existing electrical systems, in general although functioning, are at the end or have exceeded their useful life. Even with regular maintenance, systems have deteriorated over the years to the point of disrepair. Most systems are of original vintage, approximately 35 years old, and are in poor condition. The life safety systems, due to code changes over the lifespan of the facility, are no longer in compliance with current code. Switchgear is obsolete and not suited for expansion. The generator system no longer functions in the automatic mode. Fire alarm system is not code compliant. In general, due the age and condition of the facilitys electrical systems, we recommend a total replacement of these systems. Electrical Distribution System: The primary service originates on utility company Pole #4, located at the rear of the police station where it drops and runs underground across the parking lot in two 4 inch conduits (one spare) to a utility company owned pad-mounted transformer.

Primary Utility Pole Pad-Mounted Transformer

The secondary service then runs underground between the pad-mounted transformer and a 600 ampere main circuit breaker and C/T cubicle located in the Main Electric Room. An 800 ampere main distribution panel distributes power to the remainder of the facility. Panelboards exist throughout the facility. Most panels have no space/spare capacity for added circuits. NSTAR Meter #82124509 is located in the Electric Room.




Switchgear was manufactured by Federal Pacific (FPE) , is obsolete, and in poor condition.

It is unclear if safety

door sensors are functioning or exist.

Recommendations:

General:

In general, the electrical systems will require full replacement under a renovation program. Due to inability to conceal raceways, under a renovation program we recommend the use of a surface metal raceway system in finished spaces equal to wiremold. Mechanical rooms, storage rooms, maintenance garage, etc will require surface conduits.

Electrical Distribution System:

The existing secondary service and switchgear , due to its poor condition, should be replaced. Service capacity ratings are designed for a demand load of 10 watts/s.f. New lighting and power panels will be provided to accommodate respective loads and located in electric rooms. A system of computer grade panelboards with double neutrals and integral surge protective devices will be utilized to mitigate the harmonic effects caused by computers and other electronics.
