Hicks) Staff Contact(s): Richard N. Hicks Agenda Date: February 15, 2022 Item Number: 5.a Attachment(s): Reviewed By: The February Business Meeting Agenda includes an item to award the bid for the Phase 1 Renovations of the Gretna Public Library (“Project”). This portion of the Project will focus on the doors and renovations to the bathrooms at the front of the building. The cost of this portion of the Project is just shy of $90,000. The Board has approved an initial funding of $200,000, and preliminary estimates to complete the Project will require an additional $200,000. Kim Van Der Hyde, Finance Director, has identified a source of funds for the increase. The construction portion was probably under-funded, but that is what was available at the time. Construction costs have also increased significantly over the past twenty-four (24) months. Lisa Tuite and her Board of Directors have already raised over $453,000 of private funds towards the cost of all internal furnishings, a reading garden, and a digital sign for the front of the building. An additional $20,000 was awarded to hire a landscape architect for the exterior landscape design. They feel confident that an additional $200,000 will be made available from private funds to complete the landscaping. 5.a Packet Pg. 2 Property/Building Committee EXECUTIVE SUMMARY INFORMATION ITEM Agenda Title: Moses Building Maintenance Issues (Staff Contact: Richard N. Hicks) Staff Contact(s): Richard N. Hicks Agenda Date: February 15, 2022 Item Number: 5.b Attachment(s): HPBS-Pitt County Admin and Moses-Diagnostic Assessment Reviewed By: Significant issues with water leaking into the Moses Building continues to occur. Plaster on the walls is beginning to flake off, and there are concerns about mold and other issues. Most windows are in poor condition and the existing window units are contributing to a lot of the problems. County Staff hired a consultant to assess the condition of the building and a copy of their report is attached for your review and information. Kim Van Der Hyde, Finance Director, has identified some potential funds that could be used to address the issues, which could possibly include replacement of the windows, address the water issues, and explore the possibility of installing a central HVAC system. 5.b Packet Pg. 3 High Performance Building Solutions, Inc. Durham Office: 705 Watts Street, Durham, NC 27701 Headquarters: 1515 Mockingbird Ln Ste 7110, Charlotte, NC 28209 November 11, 2021 Pittsylvania County, Virginia Attn: Richard Hicks P.O. Box 426 Chatham, VA 24531 Re: Building Diagnostic Assessment for Pittsylvania County Administrative and Moses Buildings Dear Mr. Hicks, High Performance Building Solutions, Inc. (HPBS) conducted an onsite Building Diagnostic Assessment for the Pittsylvania County Administration Building and the Moses Building on October 25, 2021. Both buildings have been experiencing moisture intrusion issues: including bubbling paint and efflorescence on the interior side of the exterior walls. The moisture problems have been occurring over the life of the buildings even though attempts have been made to remediate the moisture problems. The investigation included a visual inspection to investigate and document the onsite conditions, RILEM tube testing and thermography survey of the building envelope components. Administrative Building: The County Administrative Building is located at 1 Center Street in Chatham, Virginia. The exact age of the building is unknown but it was likely constructed in the late 1970’s. It is unclear what renovations have occurred since the original construction because the County was not the first owner of the building. It was reported that some of the interior walls have been removed or added for individual offices. In 2016 one of the two roof top air handlers was replaced. The exterior wall assembly is a “barrier wall” with “reservoir cladding” meaning that the exterior wall assembly manages the intrusion of air and bulk water by relying on the integrity of the outermost surface, however the porous masonry also absorbs and stores water that does manage to enter the masonry. The challenge with this wall construction is that because the exterior face of the wall is not decoupled from the interior face, moisture can migrate through the wall assembly. Due to the age of the building, there is no insulation or capillary break in the exterior wall assembly. The top portion of the exterior wall assembly has a precast band over a CMU block wall – portions of the precast band have been painted or other portions are reported to have been sealed. The main concern in the Administrative Building is the “fuzzy growth” on the interior side of the exterior wall assembly. This “fuzzy growth” is not mold but instead is efflorescence. Efflorescence is a crystalline deposit of salts that can form when water is present in porous masonry surfaces such as concrete block and brick. When water evaporates from the surface of the masonry and salt crystals are left behind and grow as additional water evaporates. 5.b.a Packet Pg. 4 Attachment: HPBS-Pitt County Admin and Moses-Diagnostic Assessment (3025 : Moses Building Maintenance Issues (Staff Contact: Richard High Performance Building Solutions Pittsylvania County – Administration & Moses – Chatham, VA – Building Diagnostic Assessment Page 2 of 20 Efflorescence is a symptom that water/moisture is moving through the masonry. These salt crystals do not pose a known health risk and even though they appear to grow, efflorescence crystals are inorganic and should not be confused with mold. If moisture has entered a masonry wall the wall can dry both to outside and to the inside. Waterproofing on the exterior side of the wall assembly blocks moisture from escaping to the outside resulting in wetter masonry and more moisture moving towards the occupied inside space. Air conditioning also contributes to efflorescence; the air-occupied space is drier which results in a lower interior vapor pressure which also drives moisture towards the interior. As this moisture evaporates on the inside, efflorescence is left behind. Spalling seen in the exterior brick is another sign that moisture has been entering the wall assembly, and during the winter months, freeze-thaw cycles have damaged the bricks. The county facilities personnel indicated that a waterproof coating had been applied to the exterior brick within the last five years – the exact product installed was not identified while HPBS was onsite. It appears that water is bypassing the waterproofing and continues to enter the wall, and that because drying to the outside has been decreased due to the waterproofing, more water will move towards the inside causing increased levels of efflorescence. A RILEM Tube test was conducted on the brick barrier wall of the Administration Building. This testing provides a simple means for measuring the rate at which water moves through porous materials such as masonry. The RILEM tubes were placed on the face of the brick and the precast wall panel. During the RILEM testing tubes filled with water are situated to be absorbed into the masonry and the levels in the tubes are checked over a 20-minute period. An acceptable performance is achieved if the water level drops no more than 20% of the original height during the 20-minute test period. Four random sample locations were tested. The only RILEM tube test to fail was the location on the front of the building under the large overhang where it was reported that the waterproof coating was not installed. This area of the building does not show signs of current moisture intrusion, as it is shielded from weather events by the large overhang. The results of the RILEM tube test support the theory that the moisture entering the wall assembly is not from the barrier wall but rather from another source. A visual inspection of the exterior wall assembly suggests that water could be entering the wall assembly from the poorly maintained sealant joints. Sealant joints are observed at the transition between the wall assembly and the window assembly – these joints are deteriorating which can allow moisture into the wall assembly. In some locations, there is a sealant joint between the precast band and the brick wall and in others there is no sealant joint. There is also a sealant joint along the top of the precast wall panel. The coping on the parapet wall does not extend far enough past the face of the precast wall panel to direct water away from this joint or from the face of the building. The barrier wall system requires that all sealant joints are properly addressed and maintained. The likelihood of moisture entering the wall assembly at the sealant joints is high and interior efflorescence patterns around the window assembly suggests this is likely. A visual inspection of the roof assembly suggests that water could be entering the wall assembly from under the metal coping. Gaps are observed and sealant appears to be missing at the corners 5.b.a Packet Pg. 5 Attachment: HPBS-Pitt County Admin and Moses-Diagnostic Assessment (3025 : Moses Building Maintenance Issues (Staff Contact: Richard High Performance Building Solutions Pittsylvania County – Administration & Moses – Chatham, VA – Building Diagnostic Assessment Page 3 of 20 and at several seams in the coping. The coping does not extend far enough over the precast panel in several locations to direct bulk water away from the exterior wall assembly. The coping is not sloped inward to direct the bulk water away from the precast panel. Moisture is likely to enter the wall assembly from these locations and this likelihood is supported by the patterns of the interior efflorescence. Several of the patterns suggest a downward migration pattern – specifically at the conference room and IT manager’s corner office. From the interior of the building a visual inspection was conducted, including areas above the suspended ceiling system. The visual inspection identified air leakage pathways that can allow moisture to enter the conditioned space; entry of moisture laden air can increase the load on the HVAC system and cause occupancy discomfort. Air leakage pathways were observed at the top of the CMU block wall behind the precast band, at penetrations through the exterior wall and at the soffit overhangs. Also, where the roof top unit was recently replaced, air leakage pathways are observed even though spray polyurethane foam was installed around the curbing for the unit. Spray polyurethane foam degrades when exposed to UV which over time will increase the air infiltration at these locations. HPBS conducted pressure monitoring while onsite with a calibrated digital manometer. Pressure readings indicated the occupied portion of the building was under positive pressure throughout the morning inspection while the building was occupied. The pressure monitoring was only collected for the morning; however, it is not uncommon that buildings revert to negative pressure under unoccupied periods, or during some weather conditions. Also, the space above the ceiling tiles is a negative return plenum, this negative pressure will bring in outside air from any air pathways through the exterior wall located above the ceiling. The ideas that pressure imbalance is causing the efflorescence does not seem supported by the facts. Only positive pressures were observed in the space where the efflorescence is visible. Neither is the idea that the moving of interior walls has had any effect. Only a few of the interior walls go all the way up to the underside of the roof deck to create isolated zones that would be required to create negative pressure from an improperly balanced HVAC system. The light fixtures throughout the building are air return troffer fixtures which allows for return air to circulate without having a visible return grille; these “connect” most of the offices and minimize any zone imbalances. Multiple individual offices have only a supply grille and the air return troffer light fixtures which would not result in negative pressures from the HVAC system. Negative pressure may occur when there is more exhaust air than supply air – on the day of the onsite inspection this was not the case. Only one of the three exhaust fans located on the roof was observed running during the inspection. These small, spot exhaust fans do not exhaust enough air to create a negative building pressure. Visible hail damage was observed on condenser coils of the roof top units and mini-splits. The coil fins are damaged to the point where the equipment performance and efficiency will be affected. Recommendations: • Hire a roofer to remove the coping cap at select locations to verify the top of wall conditions. Depending on the findings from this invasive inspection there may be 5.b.a Packet Pg. 6 Attachment: HPBS-Pitt County Admin and Moses-Diagnostic Assessment (3025 : Moses Building Maintenance Issues (Staff Contact: Richard High Performance Building Solutions Pittsylvania County – Administration & Moses – Chatham, VA – Building Diagnostic Assessment Page 4 of 20 additional recommendations, but at a minimum the existing peaked coping be replaced with coping that extends beyond the entire top of the precast band and that slopes inward towards the interior of the roof to direct bulk water to the roof drains and not to the face of the barrier wall. Repair the top of the parapet and precast band as needed when the coping is replaced. Assure that no water is able to leak into the wall at this location. • Repair the sealant joints around the exterior glazing components. The old sealant should be removed and new backer rod and sealant installed. • Repair all sealant joints in the barrier wall system including above and below the precast panels. • Have the masonry system evaluated by a structural engineer or qualified mason to determine if the spalling brick can be repaired. • Use a fin comb to straighten the cooling fins on the HVAC units that have been damaged by hail. • Re-work the equipment curbing to ensure it is water tight and sized appropriately for the roof top unit. • Replace the recessed can lights in the soffit area with air-tight recessed can lights to reduce air leakage at this location. • When the roof is scheduled for replacement, also plan to remove all abandoned equipment curbs. Moses Building: The Moses Building is located at 21 North Main Street in Chatham, Virginia and currently houses the sheriff’s department and other offices. The building was originally constructed in 1938. The exterior wall assembly is a “barrier wall” with “reservoir cladding” meaning that the exterior wall assembly manages the intrusion of air and bulk water by relying on the integrity of the outermost surface; however, the porous masonry also absorbs and stores water that does enter the masonry. The challenge with this wall construction is that because the exterior face is not decoupled from the interior face, moisture that does enter can migrate through the wall assembly. Due to the age of the building, there is no insulation or capillary break in the exterior wall assembly and originally the building was not air conditioned. There are decorative manufactured precast stones around the exterior main entrance, quoins and a cornice ledge at the top of the building. The windows are operable with double hung wood frames and single pane glass. The main concern with the Moses building is the deteriorating interior plaster in the 3rd floor conference room. The location of damaged interior plaster correlates to the location of the decorative cornice and dripstone. There is also additional deterioration occurring around the exterior window assemblies. The wood windows are deteriorating allowing for moisture to enter the barrier wall assembly. A RILEM Tube test was conducted on the brick and decorative stone of the Moses Building. This testing provides a simple means for measuring the rate at which water moves through porous materials such as masonry. The RILEM tubes were placed on the face of the brick and 5.b.a Packet Pg. 7 Attachment: HPBS-Pitt County Admin and Moses-Diagnostic Assessment (3025 : Moses Building Maintenance Issues (Staff Contact: Richard High Performance Building Solutions Pittsylvania County – Administration & Moses – Chatham, VA – Building Diagnostic Assessment Page 5 of 20 the stone sections. During the RILEM testing, tubes filled with water are situated to drain through the masonry and the levels in the tubes are checked over a 20-minute period. An acceptable performance is achieved if the level of water drops no more than 20% of the original height during the 20-minute test period. Two random sample locations were tested. The RILEM tube test located on the stone area failed – this indicates that moisture is entering the barrier wall assembly at location of these stones. The results of the RILEM tube test support the theory that the moisture entering the wall assembly is not from the brick but rather from the stones and from the deteriorating wood windows. A visual inspection of the exterior wall assembly identified multiple penetrations through the barrier wall that were not sealed. These unsealed penetrations allow moisture into the wall assembly. A waterproof coating should not be applied to the brick face of the building as this will prevent moisture drive and wall drying towards the exterior of the building as the envelope was originally intended to function. A visual inspection of the interior of the building identified a vented attic space above the 3rd floor ceiling system. An original plaster ceiling is located just above the suspended ceiling system and is insulated from the vented attic space with a few inches of insulation. As the building was renovated several interior walls were removed to allow for more open office spaces. The removal of interior walls has resulted in damage to the plaster ceiling, leaving an open space above the removed wall. The plaster ceiling on the 3rd floor is functioning as the air barrier at this location and the lack of a continuous air barrier allows moisture laden air to enter the space and adds to the moisture load of the building. Adding air conditioning to a historic building with an envelope assembly not designed for the inward moisture drive from air conditioning can be problematic. Adding window air conditioning units or packaged terminal air conditioning units that dehumidify the interior will increase the moisture drive towards the interior. Recommendations: • Install a durable waterproof coating on the top edge of the precast stone ledge to keep water from being absorbed into the barrier wall system at this location. We recommend a self-adhered or trowel applied membrane suited for continuous exposure all along the top shelf of the stone and several inches up the brick wall. • Continuously and durably seal all penetrations through the barrier wall system including the parapet over the stone shelf. • Plan to replace or repair the wood frame windows. • When planning for a major renovation to this building the building envelope system should be properly addressed to maintain the proper balance of air, heat and moisture barriers. Providing a new mechanical system that both heat and cools the building should not be installed without also addressing the air sealing and insulation requirements of the building enclosure. 5.b.a Packet Pg. 8 Attachment: HPBS-Pitt County Admin and Moses-Diagnostic Assessment (3025 : Moses Building Maintenance Issues (Staff Contact: Richard High Performance Building Solutions Pittsylvania County – Administration & Moses – Chatham, VA – Building Diagnostic Assessment Page 6 of 20 Please find attached to this letter selected annotated photographs and building envelope comments for the construction drawings.

Hicks Agenda Date: February 15, 2022 Item Number: 5.c Attachment(s): Reviewed By: CSA/CPMT Staff is currently occupying office space on the bottom floor of the Lodge on Main Street across from the County Administration Building in Chatham, Virginia. The rent was recently increased for various reasons and County Staff was able to negotiate a one (1)-year lease extension, which is on the Board’s February Business Meeting’s Consent Agenda for approval. There does not seem to be a strong interest by the owners to negotiate a long-term lease for CSA/CPMT. County Staff is requesting that the Property and Building Committee begin discussions on a more long-term solution for CSA/CPMT office space, prior to the end of the new one (1)-year lease. 5.c Packet Pg. 24
