4. EXISTING CONDITIONS SUMMARY

The existing St. Clair County Health Department, and two annex buildings are detailed in the following existing conditions summary. The split-level main building, and attached annexes are described and analyzed for architectural and engineering integrity, as well as aspects of accessibility, Americans with Disabilities Act (ADA) and life safety.

The main building and annexes have generally been maintained over the years, with architectural and engineering updates performed as needed to keep the building serviceable. The following report will detail some needed architectural finish upgrades, ongoing maintenance issues, and some older mechanical and electrical systems in need of various upgrades. It also identifies some instances of environmental concerns related to possible asbestos composition in insulation, pipe wrap and floor tiles, with testing recommended to confirm materiality.

Accessibility is another existing building condition that is detailed in the report, noting that public and staff circulation between buildings and levels is somewhat restricted.

Going in and out of buildings is required to maintain an accessible route. The majority of the toilet rooms in the main building and the annexes are not accessible and cannot accommodate wheelchairs. All of these restrooms will be noted as needing updates to meet ADA, when any renovations would be performed in the future. Some door hardware will also need updates to meet current ADA guidelines.

Existing original construction drawings were available for review and no destructive testing or investigations were undertaken.

The following analysis is broken down by discipline, and details the Site, Main Building, North Annex, and South Annex.

Main Building:

The building is conditioned by four multizone rooftop units (ACU-1, ACU-2, ACU- 3, ACU-4). These units were installed in 2007.

o The rooftop units are provided with integral air-cooled condensing unit sections, gas fired heat exchangers, direct expansion cooling coils, single inlet air foil supply fans, 2� filter racks, and single inlet air foil return fans.

o The compressors are equipped with hot gas bypass to assist during low load conditions.

o ACU-1 has four zones, ACU-2 has five zones, and both ACU-3 and ACU-4 have seven zones. The areas served are indicated in the attached zoning plans.

o The supply and return fans have 2� spring isolation.

o The condensers utilize R22 refrigerant.

o The units are approximately 15 years old. While they have reached their median life expectancy, the units appear to be in good condition.

o Many filters were wet and partially deformed or deteriorating. This could be due to improperly balanced supply and return fans which lead to negative pressurization within the unit. (See photos below)

4-32 o The base rail of the units have a large amount of corrosion.

o Multizone units provide a limited amount of control for different thermal zones. Each zone conditions a large area of the building, allowing some areas to be satisfied while other are not.

o Multizone systems have a constant volume airflow, using a large amount of fan energy and is considered to be inefficient.

The rooftop units supply conditioned air to the spaces through a low-pressure duct system. The supply air is distributed to each space through ceiling mounted supply diffusers. Many of the grilles appeared to be covered in dirt and dust. (See photos below) Each of the multizone rooftop units are provided with shut off dampers that individually close during unoccupied mode or when the unit is not operating.

No perimeter heat has been provided for the building.

Return air for each of the units is through the ceiling plenum above the spaces.

Return grilles located in the ceiling throughout the building provide a transfer path for the return air to get into the ceiling plenum and be return to the rooftop units. Many of the grilles appeared to be covered in dirt and dust. (See photos below) Suite 312 is a tuberculosis center located on the Main Entrance Level.

The suite is designed with walls to deck in order to contain the highly contagious disease.

In addition to the special architectural design, the space is designed to maintain a negative pressure relative to the surrounding spaces.

The negative pressure is accomplished by a dedicated exhaust fan.

The age of the exhaust fan serving the Suite 312 is unknown. We noticed the exterior of the fan and the associated ductwork are heavily corroded and rusted which will reduce the equipment�s life expectancy. (See photos below) One issue that was noticed was the location of the suite. The suite is located to the back of the building, requiring the patients to travel from the entry through the main lobby to this suite.

The Maintenance Office is provided with an electric unit heater to temper the space during the heating season.

The main building is provided with a direct digital control building management system (BMS). The BMS is approximately 3 years old. The main temperature control panel is located in the Phone Room adjacent to the Maintenance Office.

The controllers in this panel are linked to the web-based program called WebCTRL. The main computer located within the Maintenance Office allows the staff to view space conditions as well as adjust them. (See photos below) The BMS system is in good condition.

The BMS is only provided in the Main building, the north and south annex buildings are not connected to this system.

The building is conditioned by three high efficient, condensing, gas fired furnaces (F-1, F-2, F-3). The furnaces were installed in 2002.

4-33

F-1 and F-2 are horizontal units, suspended from roof structure. The units serve the conference area.

o The combustion air and flue ducts are combined and routed up through the roof where they terminate to the atmosphere.

o Each furnace is equipped with a 1� disposable filter rack.

o A cooling coil is attached to the outlet of each furnace. The cooling coils are direct expansion coils with an associated air-cooled condensing unit located on the east side of the building.

o The condensing units are provided with a concrete housekeeping pad mounted on grade. (See photos below) o The PVC condensate piping from both furnaces are combined and routed through the exterior wall on the south side of the building. The piping discharges directly above the sidewalk. (See photos below) o The ventilation air for the furnaces are brought in through a single exterior wall mounted louver. The louver is located on the south side of building. The ventilation ductwork is extended and connected to each furnace�s return ductwork upstream of the furnace inlet.

o The refrigerant suction lines are insulated with flexible elastomeric insulation while the refrigerant liquid lines are not insulated.

o Pipe insulation installed on the refrigerant piping located outdoors appears to be weathered and wearing. (See photos below) o The supply ductwork is routed above the ceiling to the areas served.

o The supply air main is not insulated, but the diffuser branch ductwork is insulated with fiberglass blanket insulation.

o Supply air is distributed to the spaces through square, ceiling mounted diffusers.

o The air is returned from the space through a fully ducted system that is located above the ceiling and connected to ceiling mounted return grilles.

o The return ductwork is not insulated.

o F-2�s heat exchanger was replaced 6 years ago according to the maintenance staff. This indicates that the other two furnaces installed in the same timeframe may soon require further repair or replacement.

F-3 is floor mounted, vertical style furnace located in Custodial Closet in the center to building. F-3 serves the west portion of building consisting of multiple offices, restrooms, storage room, and a corridor. (See photos below) o The combustion air and flue ducts are made of PVC.

o The combustion air and flue ducts are combined and routed up through the roof where they terminate to the atmosphere.

o The furnace is equipped with a 1� disposable filter rack.

o A cooling coil is attached to the outlet of the furnace. This cooling coil is a direct expansion coil with an associated air-cooled condensing unit located on the east side of the building.

o The condensing unit is provided with a concrete housekeeping pad mounted on grade. (See photos below)

4-34 o The condensate piping, which is PVC, is routed from the cooling coil to the nearest floor drain.

o The ventilation air for the furnace is brought in through an exterior wall mounted louver. The louver is located on the north side of building. The ventilation ductwork is extended and connected to the return ductwork upstream of the furnace inlet.

o The refrigerant suction lines are insulated with flexible elastomeric insulation while the refrigerant liquid lines are not insulated.

o The supply ductwork is insulated with fiberglass blanket and routed above the ceiling to the areas served.

The prep counter exhaust fan discharged into the ceiling plenum.

The exhaust fan is 20 years old. This unit has exceeded its life expectancy but is in fair condition.

The building�s temperature controls system is standalone without a main building management system. Each furnace is provided with a 7-day programmable thermostat. (See photos below)

The South Annex is conditioned by three 4-ton packaged roof top units that were installed in 2015. The roof top units are 7 years old. These units are in good condition. (See photos below) The roof top units are constant volume.

The unit components are as follows:

o A single speed, scroll type compressor o A 2-stage gas heat exchanger o A standard 2� MERV 4 rated filter o A 1.5 HP, forward curved, single speed, belt driven supply fan

The roof top units are mounted on standard roof curbs, however during our field investigation the units were not accessed due to inclement weather. There is

4-35 not a permanent access ladder to the roof which makes it dangerous to maintain the equipment on the roof during the winter.

Supply air is distributed to the spaces through square, ceiling mounted diffusers. The supply ductwork above the ceiling was not witnessed during our field investigation.

The air is returned from the spaces through wall mounted transfer grilles between the rooms and the corridor. The transfer grilles are mounted below the ceiling. The corridor is used as a return path back to large return grilles mounted below each roof top unit. This is a Michigan Mechanical Code violation as indicated in section 601.2. (See photos below) The buildings temperature controls system in the building is stand alone.

A 7-day programmable thermostat is provided for each roof top unit. (See photos below) Each rooftop unit serves several temperature control zones with a single thermostat.

The perimeter spaces are provided with hot water radiators that are controlled by a local thermostat.

The two entrances are provided with hot water radiators controlled by their respective thermostats.

The hot water radiators appear to be original to the building. No leaks were witnessed or indicated by the maintenance staff. These units have exceeded their life expectancy but appears to be in fair condition. (See photos below) Heating hot water for the building is supplied by a single gas-fired cast iron boiler.

The boiler has an input of 210,000 btu/hr with a net output of 152,000 btu/hr resulting in a 72% efficiency.

The boiler is 29 years old.

The boiler has light signs of rust and damage to the casing but appears to be in fair condition. (See photos below) The boiler is not provided with a backup in the event of failure.

The leaving water temperature during the site observation was 145-degree Fahrenheit.

The boiler appears to have been installed in 1993.

The boiler flue is routed up through the ceiling tiles and terminates above the roof to the atmosphere.

During our site observation, the ceiling tiles were observed to have water damper around the flue duct. (See photos below) Water damage could either be from an active roof leak or a previous leak.

The combustion air intake for the boiler is drawn from an exterior wall louver adjacent to the system. The louver is mounted approximately 7�-0� above grade.

The combustion air intake for the boiler is located above the exterior gas meter and regulator. (See photos below) The closed loop heating system is piped in a primary configuration with two ¾ hp inline pumps circulating the hot water heating water to each of the heating

4-36 devices through the building. One pump was valved off and appears to be a standby pump.

The circulating pumps were not provided with variable frequency drives which indicated the system is a constant volume system.

The inline pumps are 27 years old. These units have exceeded their life expectancy but appears to be in fair condition. (See photos below) The hot water heating piping is routed through an underground pipe tunnel that connects to all perimeter hot water radiators throughout the building.

The hot water heating piping is insulated with fiberglass insulation and appears to approximately 1 ½� thick.

The hot water heating piping appears to be 1 ½� copper with soldered connections. Where piping was visible, green residue was present, indicating oxidation and corrosion is occurring. (See photos below) The heating hot water piping system is provided with ball valves for isolation.

The heating system is not provided with an air separator or chemical feeder typically found in hot water heating systems. Air separators and chemical feeders are installed in closed loop systems to remove air, treat the water, and reduce corrosion of the piping. This is a layer of protection for the piping system and the associated equipment.

The existing heating system is equipped with a cold water make up and pressure reducing valve, a low water cut off switch, and outside air reset. The cold water make up is connected the hot water heating supply downstream of the circulator pumps and prior to entering the pipe tunnel.

Two horizontal, compression tanks are connected to the hot water heating return piping prior to entering the boiler.

A roof mounted exhaust fan handles the restrooms.

The restrooms exhaust fan appears appear to be original to the building. This unit has exceeded its end of life and is in fair condition.

The roof mounted exhaust fan is a down blast style fan.

Main Building:

The domestic cold-water service comes from the street as a 2� pipe that passes through the slab in north-east corner of the Maintenance Office. The water service is not provided with a means of backflow prevention.

The 2� domestic water main is routed through a 2� meter. A 2� bypass has been provided around the meter without a lockable isolation valve. (See photos below) The piping increases from 2� to 2-1/2� after leaving the meter.

The incoming services are provided with a gate valve for isolation. All other valves downstream of the incoming service location appear to be ball valves. A few newer valves were indicated to be low lead. The original valves are assumed to contain solder with lead.

The piping was not observed throughout the building only in locations where insulation was removed or missing in the mechanical room. It is assumed the piping transitions to copper with soldered joints prior to leaving the mechanical room.

Most of the pipe insulation appeared contain asbestos but must be tested to confirm. Some existing insulation appeared to have been replaced with

4-38 fiberglass insulation and some insulation appeared to have been repaired with duct tape. (See photos below) According to the existing pressure gauges, the incoming water pressure is 49 PSI and the temperature is 40-degree Fahrenheit.

The 2 ½� domestic cold-water piping is extended and connected to the plumbing fixtures on all levels of the main building.

A 1 ½� cold water pipe is connected to the domestic hot water heater located within the Maintenance Office.

The domestic hot water heater a single commercial, storage type, atmospheric vent, gas fired water heater.

The water heater has an 80-gallon nominal storage capacity with an input of 199,999 Btuh/hr and a recovery rate of approximately 194 gallons per hour at 100-degree temperature rise. The water heater was replaced in 2021. The water heater set point was 120 degrees Fahrenheit.

The water heater relief valve is routed to the floor and discharges freely.

The 1 1/2� domestic hot water piping is extended to plumbing fixtures on all levels of the main building.

The domestic hot water system was observed to be copper piping with soldered joints and is insulated.

A hot water recirculation is provided with the domestic hot water system.

The hot water recirculation is made up of copper piping with soldered joints.

The domestic hot water inline return pump is located in the Maintenance Office above the water heater. The pump is activated by an aqua stat located in the hot water return piping. Isolation valves and a check valve were provided with the pump.

The sanitary system in the building flows by gravity to a 6� sanitary sewer that exits the building along the west exposure.

The existing sanitary piping was not visible during our field investigation, it is assumed to be cast iron hub and spigot piping based on the existing drawings.

The sanitary system is provided with vents at the plumbing fixtures and vents through the roof.

Based on the vent piping material extended through the roof, it is our assumption the vent piping under the roof is cast iron hub and spigot. The piping was not visible during our field investigation since the piping is concealed in walls.

There were no issues reported with the existing sanitary and vent systems.

The building is provided with primary roof drains that are connected to internal roof conductors routed down through the building and connected to two 6� underground storm sewer.

The roof sumps were clear of debris and no issues where noted. The primary roof conductor piping appeared to be PVC piping where exposed. Most of the piping could not be observed in the building since it was concealed in the ceilings and walls.

The storm sewers flow by gravity to a 10� utility connection that exits the building along the west exposure.

4-39

The existing below grade storm piping was not visible during our field investigation. The pipe material is unknown.

The existing drawings indicate a perimeter drain tile along the exterior of the building and two interior drain tiles along the lower-level walls of the north and south wings of the main building. The drain tile system is connected to the underground storm drainage system. The drain tile flows by gravity and is not equipped with a sump pump. The system is not visible and could not be verified to be installed.

Two elevators were added to the building in 1980 (42 years old). The elevator pits were not observed. Based on site observations, it appears each elevator pit is drained into a sump pump located within the elevator machine rooms adjacent to the elevator pits. These sump pumps are duplex style with water sensors linked back to the building management system. (See photos below) There are check valves on the outlet of each of the sump pumps.

The discharge piping is galvanized with threaded fittings.

The discharge piping was routed through a wall and final termination could not be observed. According to the existing drawings, the outlet is directly connected to the storm piping adjacent to the elevator shafts.

Hydraulic elevator pit drainage is required by code to discharge into an oil separator prior to connecting to the sewer or storm piping. Oil must be disposed of properly.

The maintenance staff did not report any issues with the storm system in the building.

The natural gas service is provided on the east side of the building adjacent to the existing Maintenance Office.

The high-pressure natural gas service is routed through a meter and a pressure regulator on the exterior of the building. The 2� main branches to three locations. A 1 ½� pipe is routed underground to the North Annex. The 2� pipe is routed aboveground and serves the Main Building. A 1� branch at the end of the exterior piping connects to the main generator adjacent to the gas meter.

This generator serves the vaccine refrigerator, phone server and computer server.

The 2� branch to the Main Building enters the Maintenance Office where it increases in size to 3�. The piping is connected to the hot water heater in the Maintenance Office and continues through the building to the four roof top units. The gas piping is routed through the ceiling plenum and penetrates the roof adjacent to each roof top unit.

The branch connection to the water heater also branches to a second exterior generator located south of the Maintenance Office. This generator serves the North Annex and the sump pumps.

The gas service was originally sized for one water heater, the four roof top units and an incinerator. The incinerator has been removed from the building.

The existing natural gas piping on the exterior of the building appears to be black steel threaded and has extensive corrosion. (See photos below) The interior gas piping is black steel threaded.

4-40

The gas piping serving the two generators is not provided with a dirt leg. (See photos below) The gas piping dirt leg associated with the water heater appears to be supporting the weight of the piping. (See photos below) No dirt leg is visible on the roof for each roof top unit.

The water closets found in the restrooms were wall mounted with a combination of automatic and manual flush valves. The water closets appeared to be pulling from the wall in some locations.

The lavatories found in the restrooms were wall hung with manual faucets. The strainers were missing at several lavatories.

A few lavatories were cracked and pulling from the wall.

The lavatories were not provided with temperature limiting mixing valves.

The urinals found in the restrooms were wall hung with automatic flush valves.
