METHOD

All structures and grounds were observed with non-invasive means. Building exteriors were viewed from the ground, the Synagogue's rooftop was accessed with the assistance of Carolina Air. The Freedman Center's rooftop was observed solely from the ground. Building interior assessments are based upon readily available visual observations and upon information gathered from the building maintenance records.

This document is intended to identify areas of concern for further investigations to be done by the appropriate professionals (engineers, roofers, etc.). The handicapped accessibility is assumed to have been compliant at the time of permitting and is evaluated herein based upon possible improvements, which could be designed in conjunction with any future alterations and renovations and permitted as required by present building codes.

SYNAGOGUE ASSESSMENT

1. LANDSCAPE, WALKWAYS, AND PARKING

a. Observations of paving (concrete, brick, and asphalt), site drainage, and site maintenance

1. Overgrowth of shrubs and trees adjacent to buildings. Fully remove large shrubs and trees including stumps, which are in contact with the buildings, along with pruning and thinning out plantings.

2. Plantings and concrete walkways in some areas are hindering surface drainage around both building perimeters.

3. Out fall of drainage pipes are clogged and some inlets are buried or disconnected from downspouts.

4. No parking zones should be clearly marked for accessible parking, drop-off / pick-up, exit path to the street sidewalks, and loading.

5. Improved accessibility around the building must be included with any alterations to the exterior of the building. Secondary exists from both levels should have paved routes to the street sidewalks.

6. Building signage is not visible from street. New signage should be part of exterior improvements.7. Verify storm sewer under playgrounds and record in a Facilities Maintenance Plans.

b. Recommendations

1. Trim hedges, remove and/or relocate existing plantings. $2,000 – 5,0002. Investigate, clean out, and repair drain lines. Repair replace gutters $5,000 – 10,0003. Re-stripe parking area and provide signage $2,000 – 5,0004. Renovate playgrounds and drainage $ 10,000

1

A - Downspout outflow at exterior walls needs positive surface drainage to 10' away from building.B – Clean out cast iron piping in roots of mature tree.

C – Downspout needs to drain away from building.D – Playground mulch is clogging drainage pipingat downspouts and in yard drain.

2

A – No signage at main entrance.B – No signage at pre-school entrance. Ramp to entrance of school has hazardous edge with no slope.

C – Exit route from Worship is blocked by HVAC units, landscaping, high threshold, and no walkway. See Life Safety observations for additional notes regarding this area, door, and exterior emergency lighting.D – Signage obscured by shadows and shrubs.

3

A – Overgrown shrubs outside Library and above Boiler room.B – Grate of pit down to Boiler Room. Obstruction in egress route outside exit door

C – Drop off zone undefined and no signage.D – Covered walk with no drop-off.E – Dumpster should be screened and occupies large area of parking lot. Consider alternatives and/or relocation.

4

2. FOUNDATION AND BASEMENT WALLS

a. Visual inspection of foundation wall and surrounding drainage area

1. We observed the presence of efflorescence and “wet block walls” in unfinished areas of the basement. This is in close proximity to the electrical service connection for the building, and given the southern exposure of the facade above, sloped ground at the perimeter, and the deep roof overhangs, this should be investigated by digging out a small area to determine the existence and/or condition of foundation waterproofing and foundation drain tiles around the building perimeter, as well as the water lines serving the building (Ref. Plumbing 6.B.4)

b. Recommendations

1. Foundation drain and water line investigations. $10,000 – 50,000

5

A – Boiler room wall with effervescence, East end of South wall.B – Mechanical room walls with effervescence in NW corner.

C – Boiler room walls with effervescence, SW corner and continuous across bottom of each wall.D – Mechanical Storage room wall with effervescence, West wall.

6

3. STRUCTURAL SYSTEMS

a. Observations

1. Brick columns with no cap flashing are green with algae and deteriorating top course. Repairs to wood pergola should include installation of metal cap flashing.

2. Cracking and peeling paint/stain on exposed, wood, structural roof beams on the Synagogue. Repair and stain/paint with investigation for rot and hidden conditions. Structural engineer should determine conditions. Although the weather of the building's beam ends appears cosmetic, there is possible hidden damage occurring and consideration should be given to trimming these or extending the roof drip line out from the beam end. Destructive testing may be required for assessing the extent of any rot in structural timbers.

b. Recommendations

1. Provide testing, repairs, replacements, and refinishing. $10,000 – 50,000

A - Exposed wood beams of roof and covered walkway have significant weathering damage.B – Beam end paint/stain is failing. Appears to be surface rot, and is possibly more extensive. Also, ponding around splash block

C – Close up of typical column and wood condition. Exterior brick columns have no cap flashing, missing bricks, and algae growth overall.D – Beam end condition is typical around building.

7

4. EXTERIOR WALLS, WINDOWS, AND DOORS

a. Observation exterior walls and interiors at window and door openings

1. Some step cracking at corners of masonry openings appears to have been repaired in the recent past and no major areas of this were observed to be new.

2. General need of refinishing exterior wood on structure, as well as trim, windows, and doors.

b. Recommendations

1. Refinishing, repairing, reglazing windows and doors. Repointing masonry and replacing flashings.$50,000 – 100,000

A – Horizontal mortar joint at through wall flashing below basement classroom windows has deteriorated and requires repointing, typical. Verify flashing exists, none observed at weep holes.

B – Metal window sills not sloped properly and appear to trap water at windows.

8

A – Mildew and algae growth on brick wall at Kitchen exit. Prolonged wet conditions from exposure and overflow from roof above. Note rotting fascia at corner of lower roof. See roof observations.

B – Dark discoloration, possible mildew due to prolonged wet conditions. Suspected cause is poor drainage out from classroom walls and surface outflow of downspouts.* These are typical conditions around the lower half of the building.

9

5. ROOFING SYSTEMS

a. Observations of EPDM membrane roofing and metal flashings, gutters, downspouts, and drain inlets.

1. Refer to sections 1 and 4 above for downspout outfall and drainage observations. 2. Membrane roofing appears to be at or near age for replacement. Seams peeling and hidden

fasteners are dimpled. 3. Roof drains lack protective covers from leaves and debris. 4. Small areas of ponding on 3rd day after recent rain.

b. Recommendations

Remove and replace roofing with Cool Roofing system. $80,000 – 100,000Including metal fascias, flashings, and misc. metals

A – View of the southeast corner of upper roof.B - Peeling seams of EPDM roofing membrane, and insulation fasteners pushing up. No debris protection at roof drains, and no overflow drains, typical. Roof overflow is undirected and flows over roof edge around perimeter.

C – Roof monitor, which houses secondary mechanical system. Note black rectangles where original HVAC units were located.D – This corner appears to have excess flow over the roof edge, contributing to fascia rot and brick damage below (at Kitchen exit). See section 4 image 6944 above.

10

E – Ponding at southwest corner of upper roof where typical overflow occurs.F – Peeling seams at perimeter of roofing membrane G – Leaf debris accumulating at southwest, inside corner of roof monitor. Scuttle cover is held down with loose roof drain protection basket. Replace with operable roof hatch per roof wind class and fire rating. Solar panel service is unidentified.

H – Ponding in middle area of upper roof on the west side of roof monitor.I – Ponding north west of roof monitor and peeling seams around roof drain with no debris protection. Note raised dimples in roof surface, which show fasteners below. Roof top service and maintenance likely causing damage to roof membrane due to foot traffic. Consider install of walkable membrane paths around perimeter and to mechanical access hatch.

11

6. PLUMBING

a. Observations

1. Vent stacks of Synagogue are within 1 ft. of roof surface and within 10 ft. of fresh air intake for mechanical system.

2. Sump pit observed as “typically full of of water.” Verify pump and controls as appropriate. 3. Floor seals of children's toilets of Synagogue need replacement. 4. Wet area under teachers sink in classroom area appears to be from pipe leakage, not spillage

from sink. 5. Missing bolt in cover plate of grease trap. Replace bolts and reseal. 6. Hi/Lo drinking fountain required by code, if renovations are made to classrooms. 7. There is a backflow preventer installed outside of the building in the bushes where the electric

meter is located. This is appears to be the main water service. This pipe should be checked for leaks. It could be contributing to the moisture issue on the wall behind the Main Distribution Panel in the boiler room (see photo in Foundation and Basement Wall section).

8. Most of the bathroom fixtures in the buildings appear to be old. The synagogue building appears to be used quite a bit during the week and therefore has a steady use of the bathrooms. There could be significant water savings if the existing fixtures were changed out for low consumption fixtures.

b. Recommendations

1. Additional smoke tests should be done in the Synagogue building to further identify leaks in the sewer system. Given the age of the building and the ongoing sewer problem, consideration should be given to scoping the waste lines with a camera to assess the overall condition of the system. Rooter-Man Plumbing has submitted a proposal to locate the hidden leaks produced in the second smoke test. As well as for doing a third smoke test to verify all leaks have been found.

2. Any floor drains or similar fixtures that do not receive water periodically monitored to make sure they are not dry. If there are any that are just not needed any more, they should be sealed up. For traps that are infrequently used, a little light oil should be poured into it (a tablespoon or so). This will slow down the evaporation considerably extending the time it takes for the trap to go dry.

3. Extend the plumbing vent in proximity of the kitchen hood make-up air intake vertically to a foot above the height of the RTU and the highest part of the adjacent ac units. $1,000

4. Check the water service pipe for leaks where it comes into the building. A sustained pressure test of that section of the pipe may be a good way to check that.

5. Replace (14) high water use toilets and urinal with low consumption fixtures. $10,000

A - Synagogue fresh air intake (extending from the left) facing plumbing vent stack (short white pipe).

B – Combustibles stored on top of Water Heaters are a fire hazard. Remove items and maintain clearance.

12

C – Wet area under sinks observed. Reseal around sinks and toilets where wood under laminate shows signs of water damage.

D – The lid of the grease trap, located in the Dairy Pantry is missing two bolts and not fully sealed. Scheduled maintenance must have owner sign-off to assure proper seal around trap.

13

7. MECHANICAL

a. Observations of equipment, ductwork, and air grilles.

1. Equipment rooms are cluttered and used for storage of combustible items, which is both a fire hazard and media for mold and mildew growth. Refer to LRC Report attached.

2. Air knock in piping present during walk-thru. Mechanical water piping requires bleeding to remove noise.

3. Carolina Air assisted in access of high areas and determination of system layout.

4. Sewer smell documented through-out building to plumbing vents. Extend plumbing vents min. 6' above roof surface.

5. The main cooling unit for the Synagogue building is a 20 Ton split system, dual compressor air conditioning unit. Heating is provided by a central boiler which distributes hot water to both hot water coils at the air handlers and baseboard / wall heaters.

6. The 20 ton unit serves the large worship and fellowship hall. The ductwork for this system is routed vertically through a chase from the basement to the roof. There is a horizontal roof chase that apparently has one or more control damper that are remaining from a prior control system. It is our understanding that the dampers are now manually set thru an access in the roof chase. Manual adjustments are currently being made in advance of specific events where it is anticipated that the fellowship hall will be heavily occupied. Further investigation is needed to determine if controls can be added to accomplish some zone control without having to climb on the roof.

7. The basement level of the Synagogue building is partially cooled with a 5 ton split system air conditioner. This air handler is located in the basement boiler room and has a hot water coil for heating. Based on the limited access to drawings for the building, this unit appears to serve the adjacent classrooms, hall, kitchen, offices and worship room on the south end of the basement level. It is not clear what if any system serves the bathrooms and offices on the west side of the main basement corridor. The classrooms on the East side of the corridor do not have any A/C and are heated with hydronic baseboard heaters.

8. The office located on the northwest end of the main basement corridor has been retrofitted with a ¾ ton ductless heat pump system that just serves that office. It is our understanding that this was added because sufficient air was not getting to that office.

9. The Synagogue building library and adjacent office located on main floor are cooled and heated by a 4 ton split system air conditioning unit with a hot water coil. The air handler for this system is located in the boiler room below. The supplies and return are built into the library book shelves. The adjacent office could not be accessed to determine if there were provisions for return air.

10. The kitchen is conditioned with a 7.5 ton roof top gas package unit located on the roof above the kitchen. According to the existing drawings, this unit also serves the bathrooms on the north end of the social hall. This unit does not appear to be equipped with any provisions for ventilation (outside) air.

11. Supplemental cooling and possibly heating is provided for the Social hall by a 7.5 split system air conditioning system. The supplies and returns for this system are on the north wall of the Social hall above the bathrooms. We did not get access to the room with the air handler, so we are not sure if there is a hot water coil or other heat source installed for this system.

12. The Synagogue building kitchen has a commercial hood with exhaust and make up air fans installed on the roof above. Typically such hoods are set up such that the makeup air flow rate is

14

approximately 80% of the exhaust flow. Therefore, there is typically a net negative pressure in the kitchen when the hood system is operating. As mentioned above, the roof top unit does not have provisions for outside air, so it does not provide any relief for the negative pressure. The magnitude of this negative pressure cannot be determined without further investigation into the specs of the hood.

13. There was what appeared to be mold on the diffuser blades in the ceiling of the Synagogue building Social hall. These diffusers are supplied from the main 20 ton air handler horizontal roof chase. The cause of this should be further investigated.

14. There is an exhaust fan in the lower level of the Synagogue building in a storage room on the west side of the main north-south corridor. The drawing we were provided shows that fan ducted to grills in the corridor and hospitality room and discharging through what appears to be an air well to a louver on the north end of the building. We are not sure what the function of this fan is or how it is controlled or whether it is even in working order. Further investigation is needed.

A - Hole in ceiling of Mechanical Storage from finding plumbing leaks. These are affecting air quality.B – Mildew and dust on air grilles of secondary system in synagogue. Clean grilles.

C – Storage above bathrooms should be kept clear of ducts, pipes, and mech. units.D – Stored items lean against flex ducts, causing crimps and kinks.

15

b. RECOMMENDATIONS

1. No file of drawings and systems schematics were available covering the entire existing building and all its systems. These should be developed and kept in a Building Records file, being updated regularly with maintenance, repairs, upgrades, alterations, and improvement.

2. The systems in the Synagogue building should be balanced to determine overall pressurization. This will give insight as to how air is moving around the building and what kind of controls could improve overall efficiency and comfort. Negative building pressurization may also be contributing to the spreading of the sewer odor discussed in the plumbing section.

3. Determine the condition and function of the exhaust fan in the lower level storage room of the Synagogue building. $5,000

4. Add air conditioning to the classroom on the east side of the north-south hallway in the lower level of the Synagogue building. These classes currently only have baseboard heat. Consideration should be given to using a variable refrigerant flow (VFR) system since ductwork and air handling equipment would be difficult to accommodate in those spaces given the height of the windows. A VRF system works similar to the ductless system installed in the office at the end of the hall of the lower level (see item 9 above) in that it will have only one outdoor condensing unit, but there will be numerous indoor units (one for each room). This will allow each classroom to have its own thermostat. There are several choices on what the terminal unit can be in each classroom. They can be wall mounted ductless units, small air handlers, ceiling mounted ductless units, etc. We did not go in those rooms during the site visit, so we are not sure at this point which would be best. The benefits of this system, aside from the inherent zoning capability, is that energy transfer is accomplished by distributing refrigerant piping rather than ductwork thereby requiring much less space. The downside is that the system is a little more expensive than conventional equipment but may not be more costly overall given the easier installation for this application. It also does not allow for outdoor ventilation air required by code which may or may not be applicable in a retrofit situation like this. $100,000

5. Controls for the Synagogue building main air handling equipment should be assessed in conjunction with the lower level exhaust fan and the dampers currently being manually set inside the roof duct chase. These dampers could possibly be replaced with digitally controlled actuators controlled by zone sensors to provide a more convenient and robust system. $25,000Design not included in this price.

6. We are not sure what circumstances led to the installation of the 7.5 ton unit supplementing the main unit in the Synagogue building Social Hall. Normally we do not see a room like this conditioned by a whole building unit plus and separate unit just for that room. Sometimes this leads to systems working against each other. Do heat load calculations for whole building. $1,500

7. Need to determine if the stain on the Synagogue building Social Hall ceiling diffuser is mold and ascertain what is causing it. This may require access to the duct inside the horizontal duct chase on the roof. See LRC report for findings within a normal range. Work in line 5 may resolve this issue. Clean and monitor diffusors as yearly maintenance schedule.

16

8. ELECTRICAL

a. Observations of general lighting, electrical fixtures, and system where visible.

1. No systems schematics were available covering the entire existing building. 2. Lighting fixtures appear to be old enough that replacements could greatly reduce energy use. 3. Daylighting does not appear to be maximized from the existing windows. This could reduce

energy use during the daytime. 4. The electrical service appears to have been upgraded when the kitchen was added. A new

Main Distribution Panel (MDP) was installed and the original 600A was back fed from the new MDP, as well as a 200A breaker for the new kitchen panel.

A – Main Distribution Panel (MDP) in Boiler rm. B – Old panels and devices in Boiler rm.

17

9. LIFE SAFETY

a. Observations of general layout and location of fire alarms, devises and appliances.

1. No posted occupancy or Life Safety Plan in main public entrance. 2. Not all exits are clearly marked with Exit signs in Main level assembly spaces. 3. Secondary exit routes away from the building do not safely lead to a public way (street sidewalk)

or to pt. 50' from the building. Exterior egress lighting does not appear adequate and likely requires upgrades with any exterior improvements to comply with current codes.

4. Windows have varying degrees of operability and do not have fall protection where a story above ground outside. Classroom windows are also a security and child safety hazard.

b. Recommendations

1. Create and post max. occupancy signage and Life Safety Plans in main assembly spaces, as well as As-Built drawings, schematics, and diagrams for Facilities Maintenance Manual. $5,000

2. Install illuminated Exit signs at all exits from assembly spaces. 3. Install exterior lighting per current code requirements. 4. Completely reconfigure exit path from SW corner of Worship space. Change door swing, add

stoop, ramp with railing, lighting, and relocate HVAC units. $20,000 – 40,000 5. Windows require fall protection, see Sect. 4 Exterior Walls Windows and Doors recommendations.

A – Apparent location of Fire Alarm Panel. No Fire Safety Plans posted or available. Verify with City Fire Marshal's office for records on file.B – Glass located less than 18” above floor, should be tempered, and have restrictive device for child safety at this height above ground outside.

C – Fire Exit with HVAC and other obstructions.

18

10. FINISHES FURNISHINGS AND EQUIPMENT

a. Observations of general conditions and operational status. 1. Stored food, etc. in Lobby space, not in the path of egress. There is potential for this to expand

into the exit path to the doors. 2. In the Worship space about 10% of fixed seats are not operating fully and need spring repair or

other. Dark fabric colors in this space lend to an overall dark quality of light and yet hide stains. 3. The book stand in the seating area has been modified to hold a microphone with clips and cords.

Its use and appearance could be improved by crafting wood extensions to maintain the original lines and quality of the piece.

4. Storage for worship supplies, books, yamakas, etc. is in assorted furnishings, spread through-out. 5. Daylighting in the Worship space is greatly diminished by several factors. Original design appears

to intend for light to reflect off the roof and exterior roof overhangs, and in through the high windows. Black roofing membrane has low reflectance, dark stain/paint on bottom of roof overhangs has low reflectance, and dark interior colors, finishes, and materials have low reflectance values, as well.

b. Recommendation 1. Interior renovations should include refinishing, repairs, and replacements that meet the intent of

the original design, in order to maximize the benefits from full use of daylighting with existing high windows. Stain/paint exterior soffits a light color of medium to high sheen. Replace roofing with high reflectance, low glare membrane roof (TPO or TPO coated EPDM). Replace dark interior colors with lighter ones. Refer to Sect. 5 Roofing for recommendations.

2. Have dedicated storage identified and contained with signage and built-ins to match existing. 3. Replace cushions as needed for aesthetics, upto 10% and repair seating. $5,000 – 10,000 4. Often what is acceptable conditions become unacceptable when limited upgrades are made.

A – Worship space seating needing repairs. B – Loosely stored and/or collected items in the Lobby.

19

FREEDMAN CENTER ASSESSMENT

1. LANDSCAPE, WALKWAYS, AND PARKING

a. Observations of paving (concrete, brick, and asphalt), site drainage, and site maintenance

1. For this section Refer to items 1 – 6 of Synagogue. All are applicable to the Center.2. Install leaf protection on gutters and trim trees to 10' away from building.3. Costs included in estimate for Synagogue

A – Drain thru sidewalks are clogged, typical.B – Erosion at NE corner and mudflow across sidewalk.C – Hazardous drop > 6” at edge of sidewalk.

D – Downspout at exterior wall, flowing onto pavement and into window wells. Verify pipes are clear and reconnect downspouts.E – Uneven settling of sidewalks.

1

F – Deteriorating railings at ramp and steps is causing concrete damage. Railing replacement must address concrete repair and new code requirements for railing height.G – Overgrown shrubs should be pruned or relocated away from building facade.H – Exit stair with exposed reinforcement in concrete.

I – Concrete deteriorating under guardrails of steps.J – Existing walkways are too narrow for adequate accessibility from parking and slope greater than 1:20 requires railing.K – Lack of signage to identify accessible route.

2

2. FOUNDATION AND BASEMENT WALLS

a. Visual inspection of foundation wall and surrounding drainage area

1. Building perimeter has an unidentified, black stripe just above grade. Interior finishes obstruct inspection of the basement walls with the highest grade outside. Further testing should be done to determine the nature of this condition. Cleaning the brick may also help investigations.

2. Our assumption is that prior to the addition of interior paneling, water damaged walls were properly seal with an appropriate sealant.

3. Attending to the drainage issues in section numbers (landscape, walkways, parking) could take care of these issues, recommendation is to monitor walls and interior air quality.

A – Grade outside is above window sill height and splash from pavement appears to require covering the window well. Panel reported to be installed over water damaged walls. Monitor interior air for mold.

C – Water damage in wall from unidentified, exterior source. This wall is below outside grade.

D – Wall coverings obstructing observations in key areas

3

B – Black area low on exterior brick walls. of basement where grade outside is at the window sills.

3. STRUCTURAL SYSTEMS

a. Identify areas of compromised structural bearing

1. Site built, wood truss roof. Wood framed walls with brick veneer, brick and block foundation(assumed), footing not observed.

2. Observed pervasive step cracking at corners of openings in brick veneer. Not yet a structural threat. See Exterior Walls, Windows, and Doors for images

3. Observed full height cracking up NE corner, two stories to roof eave. Structural engineer should evaluate.

b. Recommendations

1. Structural Engineering Evaluation $250 - $500

A – Extensive crack in brick veneer at NE corner, travels from roof down two stories to grade.

B – View showing bottom of NE corner. Note black area above ground mentioned in Foundation and Basement Walls section.

4

4. EXTERIOR WALLS, WINDOWS, AND DOORS

a. Visual inspection of all exterior walls and interiors at window and door openings 1. Some step cracking at corners of masonry openings appears to have been repaired in the

recent past and no major areas of this were observed to be new. However some re-cracking is occurring. (covered in section 5 roofing systems)

2. General need of refinishing exterior wood trim of roof, and weather sealing exterior doors.

b. Recommendations 1. Repoint masonry. Clean masonry and weather seal ext. door. $5000 -10,000

A – South facade with multiple areas of repointing apparent and more areas to be repointed.B – Staining at corners of window sills, and cracking at both window head and sill corners.

C – Light discoloration, possible mildew due to prolonged wet wall conditions.D – North facade with dark stained areas below windows of the main level.

5

5. ROOFING SYSTEMS

a. Observations of shingle roofing, metal flashings, gutters, downspouts, and drain inlets from the ground. 1. Disconnected gutters, downspouts, and boots are spilling around perimeter of the building.

Rusted gutters and downspouts are also failing. 2. Limited replacement of gutters has left failing pieces in the roof drainage system. 3. Shingle roofing not observed close enough for evaluation. No obvious wearing issues.

b. Recommendations 1. Repair gutters and downspouts, replace and paint rotten wood trim. $2000 - 5000

A – Gutter has separated from the roof and apparent rot of roof edge and trim. See 3961 in section 1 for erosion occurring below this condition.B – Rot at high roof edge with tree limbs touching.

C – Rot at roof edge below mix of new and old gutters and downspouts.D – Gutter leaks at disconnected joints causing water damage and algae down exterior brick below.

6

6. PLUMBING

a. Observations of plumbing fixtures for operability, water efficiency, and ADA compliance 1. Seals around toilets and sinks are failing. Re-seal unless replaced. 2. Unclear what is abandoned and if so, then is it disconnected and capped. 3. Hi/Lo drinking fountain required by code, if renovations are made to classrooms. 4. Toilets, sinks, and drinking fountain are not ADA compliant and do not meet new code

requirements. Replacements must comply with present code. 5. Plumbing accessories and grab bars are not ADA compliant. Replacements must comply with

present code. b. Recommendations 1. New drinking fountain - $1000

2. New toilets (6) - $3000 3. New sinks (4) - $1000

A – Existing plumbing and accessories on main level. B – Existing sink with single handle faucet and drinking fountain, in basement level and clean out on wall.C – Out of order drinking fountain is not compliant for accessibility.

7

7. MECHANICAL

a. Observations of equipment, ductwork, and air grilles. 1. Equipment rooms are cluttered and used for storage of combustible items. 2. Carolina Air assisted in the access of high areas and determination of system layout and function.

They stated having submitted a proposal for a total replacement and redesign of the buildings HVAC system. This proposal should be considered as part of any master planning.

3. The building is heated by gas furnaces. The upper floor is served by two 5 ton units located in the attic which are equipped with A/C coils. The basement is also served by two gas furnaces which do not have cooling coils.

4. Zone dampers have been installed in the building main supply trunk serving the front meeting room in an effort to provide some control in that room during periods of use. These dampers will close when that room is not being used, but from what we can tell it will not be able to zone the front room independent from the rest of the first floor. In other words, if the zone dampers open to supply the front meeting room, the rest of the building is also being conditioned.

5. The outside air for the basement furnaces is being drawn through a duct which draws from a space that was previously a plenum of a much larger system that was replace by the current gas furnace systems. This space had a large louver in it until recently when it was replaced with a window. This effectively closed off the outside air intake. Therefore, the only ventilation for the basement floor is whatever is pulled under the door to that space (it appears to be damaged) and through any other cracks or breaches in that space. Pulling untreated air into that space will cause damage in the long runand strain the system to pull in air through cracks.

6. The basement furnaces were replaced at some point with like units that were set in front of the old furnaces. The old furnaces were abandoned in place and remain today with limited access to them. They appear to have been completely disconnected and it is our understanding that their only use is for spare parts for the newer furnaces.

7. The basement of the building has a very low ceiling. The ductwork is routed through a soffit along the edges of the hallway with supply registers through the walls to the classrooms. Air is returned from the classes through transfer ducts locate in the hallway walls to a large return in the wall of the mechanical room at the end of the hall. Current code would not allow the return to be routed through the hallway.

8. The exhaust fan in the basement boy’s bathroom has an inconvenient switch location for the exhaust fan and the fan is extremely noisy.

b. Recommendations1. No file of drawings and systems schematics were available covering the entire existing building

and all its systems. These should be developed and kept in a Building Records file, being updated regularly with maintenance, repairs, upgrades, alterations, and improvement.

2. The ductwork for the upper floor of the Annex Building should be reworked to zone the front meeting room separately from the main room in the center. This could be accomplished using the existing main trunk lines and reconfiguring the flex duct connections such that the existing diffusers in the front room, entrance and forward side of the main room are supplied by one air handler and the rest of the diffusers in the main room and the back of the building are connected to the other system. This effectively allows the front of the building to be controlled by one of the systems and the back by the other. A transfer grill would need to be added in the wall between the two large rooms to allow return air from the front room to get back to the existing return on the back wall of the main room. Thermostats would need to be relocated such that one is in the front room and one is in the main central room toward the back where the returns are.

3. The lower level of the Annex should have the existing mechanical/electrical room renovated. The existing ductwork should be reconfigured such that the ventilation air is drawn directly from the building exterior rather than through the old plenum room. The old gas furnace units should be removed to make room in the space for the possible addition of cooling to the system (see below). Unused electrical components and old plenum structure should also be removed.

4. There is some evidence of excessive moisture in the lower level of the Annex building. This may be due to exterior water intrusion issues or other causes. We saw nothing that attributed excess

8

humidity to the air systems (other than in the old plenum space), but if excess humidity or high temperatures have been experienced in the lower level during the summer, consideration should be given to adding air conditioning coils to the existing gas furnaces. There does not appear to be enough head room to add the coils to the existing vertical units, but if those units are adaptable to horizontal orientation and the obsolete equipment is removed as described in the previous recommendation, the units could be laid down horizontally so the coils could be accommodated. Two new outdoor condensing units would need to be installed and available power for the new condensers would need to be verified.

5. Basement mechanical room, remove old equipment, reconfigure. Newer equipment and add A/C to basement. $14,000

6. Zone upper level HVAC. Add attic access and zoned controls. $18,000

8. ELECTRICAL

a. Observations of general lighting, electrical fixtures, and system where visible.

1. There is a great bit of electrical equipment in the basement mechanical room that appears to be obsolete and no longer in service. Much of this appears to be associated with HVAC controls and other systems which have since been replaced or abandoned. It is recommended that all of the unused equipment be removed. This will make it easier for future maintenance and repair and there may be some recycle values in the old components.

2. No systems schematics were available covering the entire existing building.

b. Access electrical systems and remove derelict equipment. $1000

A – Exposed wiring in kitchenB – Mix of old and new electrical.

C – Exposed patches and connections in wiring.

9. LIFE SAFETY

a. Observations of general layout and location of fire alarms, devises and appliances.

1. No posted occupancy signage or Life Safety Plans were displayed in main public space. 2. Not all exits are clearly marked, with Exit signs in Main level assembly spaces. 3. All exit routes outside building do not lead to a public way (street sidewalk) or to pt. 50' from the

building.

b. Draw and post life safety plan, add exit signage. $2000

A – Exit path is blocked by storage of items and cabinets in corridor. Width of corridor may allow for these to be placed on the opposite wall to maintain clear path to door with panic hardware. If only one door is the required exit, then locate sign over the panic hardware.

B – Exit sign is not visible from center of corridor. Install sign on ceiling. Verify clear height requirements, due to low ceilings.

November 8, 2013 Ellen Cassilly Architect, Inc. Ms. Ellen Cassilly 600 Foster Street Durham, NC 27701 Re: Limited Environmental Fungal Indoor Air Quality Investigation with Airborne and Surface Fungal Sampling at Beth El Located at 1001 Watts Street, Durham, NC LRC Project – 13-1804 At your request on, November 6, 2013, LRC Indoor Testing & Research, Inc. (LRC) performed a limited environmental fungal Indoor Environmental Quality (IEQ) inspection that included airborne and surface fungal sampling at the property listed above. This fungal inspection was requested to characterize the types and levels of airborne and surface fungi in the building and make recommendations accordingly. LRC performs all water-damage and fungal investigations with sampling and recommendations in accordance with guidelines published in Bioaerosols: Assessment and Control, by the American Conference of Governmental Industrial Hygienists (ACGIH), in Mold Remediation in

Schools and Commercial Buildings by the United States Environmental Protection Agency (USEPA), and in the currently recognized and accepted industry standards including the ANSI/IICRC S500 Standard and Reference Guide for Professional Water Damage Restoration

Third Edition (S500) and the ANSI/IICRC S520 Standard and Reference Guide for Professional

Mold Remediation (S520). Our inspection included the following: 1. Visually inspect the lower level. 2. Measure moisture contents of representative building materials in the inspected areas. 3. Measure temperature and relative humidity indoors and outdoors. 4. Collect representative non-viable spore trap air samples indoors and one outdoors for

comparison. 5. Collect representative non-viable surface tape lift samples of representative visible or suspect

fungal growth. 6. Provide a written report describing the survey results and comparing those results to accepted

guidelines and directives. This report includes a summary of data, Certificates of Laboratory Analysis and a remediation protocol, if needed, based on the ANSI/IICRC S520 Standard

and Reference Guide for Professional Mold Remediation.

VISUAL INSPECTION, RELATIVE HUMIDITY, AND MOISTURE MEASUREMENTS A Protimeter Survey-Master moisture meter was used to measure moisture levels on representative hard surfaces. Typically, moisture contents approaching 17% and greater represent excessive moisture on hard wood surfaces (wood) in conditioned spaces; however, in non-conditioned spaces wood and semi-porous materials may approach these threshold levels naturally due to seasonal changes in temperature and humidity. The temperature and relative humidity are summarized in Table A below. The relative humidity met the current ASHRAE Standard to maintain indoor relative humidity between 30-60%.

Table A – Temperature and Relative Humidity by Location

Location Temperature (°F)

Relative Humidity (%)

Gathering Space-Upstairs 70 51% Rabbi’s Emeritus Office-lower level 72 53% Hallway at Classrooms 76 50% Outdoor Air-at lower level side entry and parking lot 61 50%

Descriptions of locations in this report are from looking at the building from the street front. This inspection was limited to the lower level of the building. General Observations: The lower level appears to be a well-maintained space. Several stained ceiling tiles were noted. In the furnace room located off Room 6 the door was open to the classroom. Heavy efflorescence was noted on the block wall. Contents in this unconditioned space were mostly stored in cardboard boxes. Particulate was noted on the grills of the supplies and returns. A representative surface sample collected (Sample 06) showed the particulate had only Occasional settled fungal spores. In the Rabbi Emeritus office the door was closed and the room was rather stuffy. In the Girls Bathroom the floor measured slightly wet around the toilet at all three stalls and in the Boy’s Bathroom wet on the floor at the two stalls on the left. In the Adult Bathroom the floor measured slightly wet under the sink. SAMPLING METHODOLOGY Air Samples. Currently there are no regulations regarding acceptable airborne fungal levels. Airborne fungal spores are ubiquitous in the outdoor and indoor environment. The guidelines followed in this report for the assessment and/or remediation of airborne and surface fungi are published in Bioaerosols: Assessment and Control, by the American Conference of Governmental Industrial Hygienists (ACGIH), in Mold Remediation in Schools and Commercial Buildings by the United States Environmental Protection Agency (USEPA), and in the ANSI/IICRC S520 Standard and Reference Guide for Professional Mold Remediation. Airborne fungal assessments are performed by comparing results from volumetric samples taken indoors to samples taken outdoors. Airborne fungi levels in non-problem indoor environments generally are less than or

Page 3 of 5

approximately the same as those outdoors and also show a similar composition and/or taxonomic predominance. Problems are usually implicated in the indoor air when one or more fungal genera or species are present in a much greater concentration indoors compared to outdoors. Sampling results are shown in the Certificates of Laboratory Analysis attached to this report. Results are discussed below. Surface Samples. Surface sampling results should follow guidelines as stated in the ANSI/IICRC S520 Standard and Reference Guide for Professional Mold Remediation. Under normal circumstances, building materials that appear clean and free of dirt, water damage, and/or fungal amplification should show “Condition 1” or “normal fungal ecology”. Condition 1 is described in the Standard as “an indoor environment that may have settled spores, fungal fragments or traces of actual growth whose identity, location and quantity are reflective of a normal fungal ecology for a similar indoor environment”. Results from sampling “clean” surfaces, if performed, should show that there is no evidence of fungal amplification. Condition 2 is described as “an indoor environment which is primarily contaminated with settled spores that were dispersed directly or indirectly from a Condition 3 area, and which may have traces of actual growth”. Condition 3 is described as “an indoor environment contaminated with the presence of actual mold growth and associated spores”. Representative surface tape lift samples were collected as discussed below. Surface samples may be taken either with a tape lift or a swab and are analyzed microscopically. Sampling results are shown in the Certificates of Laboratory Analysis attached to this report. Results are discussed below. SAMPLING RESULTS Total Non-viable Spore Air Sample Results. Representative samples were taken for total airborne fungal spores with a calibrated Buck spore trap. Total airborne fungal spore sample volumes were 75-liters. Outdoor total fungal spore level (Sample 05) was measured at 4,650 Spores/m3 that was comprised of Basidiospores (80%), Cladosporium (14%), and 2% or less of various other fungal spores. Air sample results are detailed in the attached Certificates of Laboratory Analysis and summarized in Table A below.

Table B – Air Sampling Results

Sample # Location Total Fungal Spores (Spores/m3)

01 Gathering Room-Upstairs 180

02 Rabbi Emeritus Room-Lower Level 1,040

03 Between Rooms 4 & 5 250 04 Between Rooms 6 & 7 790

05 Outdoor Air between lower level side entry ad parking lot 4,650

The total fungal spore counts in the indoor air samples were less than the outdoor air on this day.

Page 4 of 5

The indoor air samples collected from the gathering room (Sample 01), hallway between rooms 4 & 5 (Sample 03), and between rooms 6 & 7 (Sample 04) were composed of common outdoor fungi with no spikes in the fungi commonly associated with the water loss fungi. The indoor air sample collected in the Rabbi’s room was predominately comprised of Penicillium/Aspergillus Group spores unlike the outdoor air. Spores in this grouping are commonly considered to be among the water loss fungi. The results therefore suggest an altered indoor fungal environment in the Rabbi’s office. Surface Non-viable Tape Lift Sample Results. A representative surface tape lift sample was collected from a suspect surface. Tape lift samples are collected to confirm visual observations. Sample results are detailed in the attached workbook and discussed in the body of the report. The surface sample collected from the ceiling diffuser showed a Condition 1, as described above. CONCLUSIONS AND RECOMMENDATIONS Results as reported by LRC apply only to the day of this inspection. LRC cannot and does not warranty that other parts of the structure were completely free or that the structure will remain free in the future from hidden sources of moisture or fungal contamination. All water damage and fungal remediation should follow guidelines as stated in the ANSI/IICRC S500 Standard and Reference Guide for Professional Water Damage Restoration Third Edition (S500) and in the ANSI/IICRC S520 Standard and Reference Guide for Professional Mold

Remediation. All work should follow recommendations therein to protect workers, occupants, building spaces from dusts and debris during remediation and removal of fungal contaminated materials. The source of the altered fungal environment in the Rabbi’s Office is not known to this inspector. Our recommendations specific to this project are as follows:

Replace stained ceiling tiles and inspect the cavity above to determine if a leak is present. Inspect the ductwork for signs of condensation.

Clean supply and return grills. In the Rabbi Emeritus Office on the lower level you may wish to operate a HEPA filtered

air scrubber for a minimum of 100 air exchanges to cleanse the air. During the hot humid months it is recommended that the relative humidity be monitored and it may be beneficial to operate a dehumidifier.

In the Furnace Room it is recommended that contents be stored in plastic containers or bags. The door should remain closed when the room is not in use. It appears a water issue is present on the wall and you should consider consulting a water proofing company to evaluate the area.

You may also wish to consult with an HVAC specialist to evaluate the system.

4. The Smut, Periconia, myxomycete group is a group composed of three different types of organisms whose spores have similar morphologies.

Smuts are plant pathogens, Periconia is a relatively uncommon mold indoors, and myxomycetes are not fungi, but slime molds. Although these

organisms do not typically proliferate indoors, their spores are potentially allergenic.

5. Rusts are plant pathogens. These fungi do not typically grow indoors unless an infected plant is present. Rust spores are potentially allergenic.

6. The colorless spores groups contains colorless spores which were unidentifiable to a specific genus. Examples of this group include: Acremonium,

Aphanocladium, Beauveria, Chrysosporium, Engyodontium, Fusarium microconidia, some arthrospores as well as many others.

Direct Microscopic Exam Reporting

Reporting Quantification Levels are as follows:

We use a 400x magnification microscope.

3. Hyphae are the tubular filaments of fungi. Hyphae can fragment and become airborne much like spores and are potentially allergenic.

Report Information

DETECTION LIMITS (DL) for samples are the minimum number of spores or colonies forming units that can be satisfactorily identified for each sample

type.

1. Penicillium/Aspergillus group spores are characterized by their small size, round to ovoid shape, being unicellular and usually colorless to lightly

pigmented. There are numerous genera of fungi whose spore morphology is similar to that of the Penicillium/Aspergillus type. Two common

examples would be Paecilomyces and Trichoderma . Although the majority of spores placed in this group are Penicillium , Aspergillus , or a

combination of both, these are not the only two possibilities.

2. Basidiospores are primarily transported indoors from outdoor sources and rarely grow indoors. A high basidiospore count indoors can be indicative

of a wood decay problem or wet soil, and should be verified if and an outdoor source of the spores is not present.

SPORE TRAP SAMPLES: Calculations based on volume of air sampled & percentage of slide counted,

i.e. DL = 1000 L / 75 L if 100% of the slide is counted.
