The building construction was completed in 1985. Since the construction was completed, various problems have occurred including roof, wall, and window leaks. The study primarily focused on the administrative areas as well as the detention tower. This report presents an initial observation of the building structure and the results of mold testing. It is intended to provide an opinion of the structural integrity of the building structure and to determine if mold spores discovered inside the building present elevated health risks when compared to mold naturally occurring outside. This report only addresses the structural integrity of the building and mold testing and does not include architectural and plumbing fIxtures, or electrical, mechanical, and plumbing issues. We have determined that the building structural components are safe in accordance with the 1985 Standard Building Code. A copy of the design code for this project, the 1982 Standard Building Code, could not be obtained during the course of this evaluation. However, the structure was evaluated by using the 1985 Standard Building Code. In general, later editions of the Building Codes are usually more conservative. The building frame consists of a concrete column and beam system with a concrete pan and joist floor system. Minor cracks were observed on the underside of some of the floor panels. The cracks appear to be non-structural and do not indicate structural concerns at this time. The exterior walls are formed of 20 gauge metal stud curtain walls which connect to the building frame. The curtain walls were checked for structural strength and deflection and found to conform to the 1985 Standard Building Code. During our examination of the exterior surfaces of the building, we observed that the Exterior Insulation and Finish System panels were not fully connected to the curtain wall. The exterior panels were warped or bowed out at many locations and could be pushed inward indicating the failure of some of the connections. This concern is non-structural but could allow moisture to enter the wall cavity and cause corrosion of the steel curtain wall system. Corrosion was visible on some of the lower curtain wall connections. Thirteen (13) tape lift and swab tests and nineteen (19) air tests were performed by an Augusta environmental fIrm, Alternative Construction & Environmental Solutions, Inc., at the facility. The test results indicated that approximately 17 different types of mold spores are present in the building. Ten (10) of the mold spore types were identifIed outside. In most cases, the mold spore comparisons of the inside and outside of the building were approximately equal. The penicillium mold spore counts were much higher inside of the buildings when compared to the outside air test. Based on this testing, we have determined that the elevated mold levels inside the building are signifIcant and could possibly present an increased health risk to individuals who may currently suffer with allergies or other respiratory health problems. 1 I I I I I I I I I I I I I I I I I I I The detention tower was tested on all four levels and found to have mold spore counts less than the outside air. We have therefore concluded that the mold spore counts in the detention tower are normal and should not be considered to be a problem at this time. The corrective action recommended in this report includes removing the source of the moisture, repairing the damaged Exterior Insulation and Finish System (E.I.F.S) and curtain wall studs, and then chemically removing the mold from the building by using proper cleaning methods and procedures. Furthermore, the facility should be retested following the execution of the recommended repairs and improvements. 2 I I I I I I I I I I I I I I I I I I I GENERAL Recently, after opening a section of the northern exterior wall of the Augusta Joint Law Enforcement Center, representatives from the City of Augusta discovered corroded light gauge steel curtain wall studs at the first level slab connection. Furthermore, mold was also observed in the wall cavity at the same location. Concerned with the structural integrity of the facility as well as the significance of the mold discovery, The Augusta Commission authorized Cranston, Robertson & Whitehurst, P.c. to conduct a structural evaluation and mold survey of the Augusta Joint Law Enforcement Center located at 401 Walton Way in Augusta, Georgia. This report has been prepared for the purpose of performing a limited structural analysis and mold survey of the facility. The Augusta Joint Law Enforcement Center is comprised of four (4) primary building areas. These structures include a two level administration building housing offices and courtrooms, a three level building housing the Sheriffs Department, a four-level detention tower above the Sheriffs Department Building, and a separate mechanical building on the opposite . side of the vehicle sally port from the Sheriff s Department. This report presents our findings and recommended corrective action based on a visual observation of the building, review of the structural plans, and physical testing of the facility. A visual observation may be defined as an examination of the structural elements of the building that are accessible and in clear view to the naked eye at the time of the observation. Portions of the building surfaces were not removed to further evaluate specific framing and foundation elements of concern. This report only addresses the structural integrity of the building and the evaluation of mold and does not include architectural and plumbing fixtures, or electrical, mechanical, and plumbing issues. DISCUSSION Building Structure Survey: The facility consists of a primary front public building which houses courtrooms, offices, records storage, and conference rooms. The Sheriff s Office Building houses training rooms, photo and crime laboratories, offices, armory, evidence room, and records offices. The detention tower includes 4 primary floor levels, each with two levels of detention cells. The detention tower is considered as the 3rd, 4th, 5th, and 6th floor above the Sheriffs Office Building. A mechanical building is located to the north of the sally port behind the Sheriffs Office Building. This report addresses only the structure of the two office and courtroom buildings and the detention tower and does not include the mechanical building. The building frame consists of a concrete column and beam system with a concrete pan and joist floor system. Minor cracks were observed on the underside of some of the floor pan sections. The cracks appear to be non-structural and do not indicate structural defects at this time. Some of the cracks were observed to have calcium carbonate deposits which indicate that some moisture has been absorbed into the concrete floor system at some time during the life of 3 I I I I I I I I I I I I I I I I I I I the facility. Random floor and roof areas were checked for structural capacity using the following live load pressures taken from the structural plans of the building facility: Building Area Live Load Pressure (pst)(pounds per square foot) Roof 20 Mechanical Room Floors 125 Corridors and Assembly Areas 100 Office Areas 50 Records Storage 150 Detention Cells 40 Laundry 200 The building structure was designed in accordance with the 1982 Standard Building Code. A copy of the 1982 Standard Building Code could not be obtained for this evaluation. However, since these design pressures also conform to the live loads required in the 1985 Standard Building Code, the 1985 Code was used in the evaluation. The exterior walls are formed of 20 gauge curtain walls which connect to the building frame. The curtain walls were checked for structural strength and deflection and found to conform to the 1985 Standard Building Code. During our examination of the exterior surfaces of the building, we observed that the Exterior Insulation and Finish System (E.LF.S.) panels were not fully connected to the curtain wall. The exterior panels were warped or bowed out at many locations and could be pushed inward indicating the failure of some of the connections. This concern is non-structural but could allow moisture to enter the wall cavity and cause corrosion of the steel curtain wall system. A review of the original building plans and an observation of selected structural components was performed. The results of our analysis did not indicate any areas that were over- stressed or that require further study at this time. Mold Survey: Several areas were identified in the facility where moisture has entered into the building. This moisture is caused by roof leaks, wall separations, ground water penetration, and window leaks. While evaluating the building structure, the site was observed to have very little slope away from the building structure. Some grassed areas around the building were observed to be ponding water or actually sloping toward the building. This condition allows surface drainage to collect at the building foundation and increase the risk of moisture exposure to the E.I.F.S. and curtain wall system at the ground. This moisture appears to be contributing to mold spore growth on various building components on the exterior walls of the facility. 4 I I I I I I I I I I I I I I I I I I I Physical testing for mold was performed by Alternative Construction & Environmental Solutions, Inc. (ACES) at the facility using three methods. The retrieval of the mold used in these analyses included the use of tape lift for mold spores that are fixed to building components, swab sampling of suspect surface colonies, and air tests using BioCassettes for testing airborne fungi. Mostly random locations were selected to retrieve mold samples in the facility. However, some specimens were retrieved in potential problem areas identified by personnel working in the facility. The locations of the test sites are indicated on the area plans included with this report as Appendix A. The report prepared by ACES is included with this report as Appendix B and summarized as follows: Tape Lift and Swab Test Results: One (1) swab specimen and twelve (12) tape lift specimens and were retrieved from various locations in the two administrative buildings and detention tower of the facility. The locations were selected randomly and are indicated on the area plans in Appendix A. The tape lift specimens were retrieved and examined under a microscope in the laboratory. The tape lifts indicated that four (4) different types of mold are fixed to building components. The mold types identified from the tape lifts are as follows: Tape Lift/Swab Specimen No. Location No. Mold Type Identified AT-l 1 None AT-2 2 None AT-3 3 Stachybotrys AT-4 4 Stachybotrys AT-S 5 Stachybotrys AT-6 6 Penicillium!

Two tests were taken outside of the buildings and 17 were taken at various locations inside the facility. The exterior air samples were taken to be used as a comparison of the mold spores detected on the inside of the building. It is important to note that the outside air mold spore counts can differ on a daily basis based on atmospheric and environmental conditions. However, the inside and outside air samples were taken on the same day which should yield results that are relative. In general, the mold counts on the inside of the building should be 30 to 80 percent of the mold counts in the outside air. The air sampling locations were selected randomly and are indicated on the Sampling Location Plans in Appendix A. Some samples were taken near HV AC supply vents to evaluate the HV AC supply air. The specimens were retrieved and sent to Environmental Microbiology Laboratory, Inc. in San Bruno, California for examination. The results were returned indicating that nineteen (19) different types of airborne mold are located at the facility site. Ten (10) types of airborne mold are located outside of the facility and seventeen (17) types are located on the inside of the facility. The mold types identified from the BioCassettes are as follows: Test Location (Ref.

Appendix A) 7 I I I I I I I I I I I I I I I I I I I CONCLUSIONS Structural Evaluation: Based on the review of the structural building plans and selected structural analyses performed on some of the building components, it is our opinion that the building structure is safe and conforms to the 1985 Standard Building Code. The Exterior Insulation and Finish System or E.I.F.S. has separated at various locations allowing moisture to enter the wall cavity and cause corrosion of the metal curtain wall studs. This building component is not a primary structural system and should not be considered as a public safety issue. However, failure of this system will allow moisture to enter the building and cause other non-structural problems and should be corrected. Mold Evaluation: Increased moisture in the building caused by groundwater penetration, roof and window leaks, and separations in the E.I.F.S. are believed to have caused mold to grow and become airborne on the inside of the building. Twenty (20) different types of mold spores have been identified at this site by using tape lifts, swabs, and air tests. Seventeen (17) types of mold spores are located in the facility and are approximately equal to or exceed the mold spore count of the outside air. According to the report prepared by ACES, the mold spore count that was identified on the inside of the building should be between 30 to 80 percent of the mold spore count on the outside of the building. Additionally, the study identified other mold spores that were not present on the outside of the building. This finding appears to indicate that the mold is considered to be excessive on the inside of the building and could possibly cause elevated respiratory health risk for certain personnel working in the building that are sensitive to mold. The tape lifts taken at the HV AC supply vents yielded negative results for mold. This finding is believed to indicate that the existing HV AC system is not a contributing factor to the mold problem in the buildings. Currently, there are no known national standards or maximum spore counts that could be compared to this facility. Six (6) air samples and 3 tape lift specimens were taken from the detention tower. Mold was identified in the detention tower on all four levels by the BioCassette air sampling. The tape lifts did not indicate the presence of any mold spores. However, the spore counts are much lower inside the detention tower than in the outside air. It is therefore concluded that mold detected on the inside of the detention tower is normal and not considered to be a problem at this time. 8 I I I I I I I I I I I I I I I I I I I RECOMMENDED CORRECTIVE ACTION This report has presented the results of a limited structural study of the Augusta Joint Law Enforcement Center building structures and has also identified and evaluated several types of mold that are present in the building. At this time, there are no recommendations for primary structural rehabilitation. Mold spore counts appear to be elevated in the two administrative buildings and the following corrections are recommended: 1. It is very important that the source of the moisture be removed. This will involve regrading the site at some locations, adding additional surface drainage around the building, correcting the failing E.I.F.S., replacing corroded metal curtain wall studs, repairing window leaks, and repairing roof leaks. 2. After the source of the moisture has been removed, the mold in the building should be professionally removed using proper cleaning techniques. This work should be performed by qualified personnel that specialize in mold removal. Brushing the mold from building surfaces is not recommended as this method could allow fixed mold to become airborne. 3. Gypsum wall board and ceiling tiles damaged by moisture should be replaced. 4. Following the execution and completion of this corrective action work, the random interior building areas and outside air should be retested. The air samples should indicate that the mold spore counts on the interior of the building have dropped to less than 80 percent of the mold spore counts on the exterior of the building. 9 I I I I I I I I I I I I I I I I I I I Appendix A Sampling Location Plans ~({8 r't .1' oJ ----. ~ .. ,p,<e ."" t ~ @=~~~li . .

'\ 1450 Greene Street - Suite 510 · Augusta, GA 30901 Telephone: 706-262-2000 · Facsimile: 706-262-3299 · www.aces~u~a.com September 9,2004 Client: Cranston, Robertson, & Whitehurst 452 Ellis Street Augusta; Georgia 30901 ATIN: Mr. Jim Cranford' Project: Limited Indoor Air Quality Investigation Richmond County Judicial Center 401 Walton Way Augusta, Georgia Report Number: 186-103-002 1.0 SCOPE At the request of the client, representatives of Alternative Construction & Environmental Solutions, Inc., conducted a Limited Indoor Air Quality survey of the RJchmond County Judicial Center at401 Walton Way, Augusta, Georgia. This survey was for the purpose of evaluating the facilities air quality due to moisture problems. 2.0 SITE OBSERVATIONS A walkthrough of the facility was conducted on August 10, 2004 with representatives from the Judicial Center. During this walkthrough, numerous areas inside walls, on the walls under the paint, and on HV AC vents were identified that had discoloration associated with mold growth. A high level of moisture was also noted throughout the facility. Through discussions with the representatives it was agreed that at least 10 surface and 10 culturable air samples were needed to start accessing the types and levels of fungi located in the facility. Sampling was conducted August 23, .2004. Additional areas were identified at this time in which sampling would help evaluate the overall air quality. This sampling was accomplished August 24, 2004. The samples were properly packaged and transported to Environmental Microbiology Laboratory Inc. for analysis. Alternative Construction & Environmental Solutions, Inc. Report Number: 186-1 03-002 Page I of4 I I I I I I I I I I I I I I I I I I I 3.0 FINDINGS a. Evidence of elevated levels of moisture was found throughout the facility. Ceiling tiles showed stains from moisture, moisture damage was found in walls, and evidence of potential fungi growth was found in walls, on ceiling tiles, and ventilation returns. This moisture is beneficial to the growth of fungi in the facility. b. Sampling was conducted throughout the facility to determine the culturable air fungi levels. This sampling, shows the airborne types and levels of fungi in colony forming units. It is important to remember that there are no set legal standards for the levels that can be found of fungi. Attachment I identifies the sample number and location. Attachment II lists the fungi found, by sample number, in colony forming units. A sample was collected outside of the facility as welL By sampling outside of the facility. we call determine fungi that are naturally occurring in the general area and establish a background level for it. Attachment III and IV are charts that show the highest levels found inside the facility compared to the levels found outside for each fungi identified as airborne. Some types of fungi found inside the facility were not found outside. c. There were tape and swab samples collected directly off surfaces such as walls and ventilation returns to determine levels, if any, of fungi growing on these objects. This helps identify fungi that is or can be airborne if the right conditions exist. The tape and swab samples showed alternaria, aspergillus, chaetomium, penicillium, and stachybotrys spores were detected. These fungi as well as additional types were found in the air sampling. 4.0 Conclusions a. Any areas where water infiltration or leaking is occurring should be repaired and dried as soon as possible. This will help remove the moisture that the fungi need to grow. b. Again it is important to remember that there are no set legal standards for the levels that can be found for these fungi. The fungi are naturally occurring and in the air around us at all times. However, elevated levels due to added moisture in an area can have adverse health effects. Levels that may not affect some individuals may be more detrimental to others who are more sensitive to them. c. As a general guideline indoor spore levels usually average 30 to 80% of the outdoor spore levels at the time of sampling, with the same general distribution of spore types. A substantial increase of one or two spore types which are not reflective of the outside distribution of spore types is usually indicative of indoor mold growth. Based on observations and sampling results there are elevated levels of some fungi and additional types of fungi found throughout this facility.

Although certain items can be cleaned of visible growth, not all surfaces can be cleaned. Items such as drop ceiling tiles, drywall, bulletin boards, etc cannot be thoroughly cleaned due to the porous nature of the material. These items should be 'replaced whenever feasible. Whenever replacement is not feasible cleaning can be attempted but will be limited in its effectiveness. We can advise on the proper ways to clean if needed. e. It should be noted that microbiological growth can and probably will reoccur if the source of the moisture is not corrected and maintained as appropriate. Many of the spores are naturally occurring and willre-grow with proper moisture, temperature and food source.
