MOLD INSPECTION REPORT

For the Subject Property:

UCD Anschutz Medical Campus Building 402 – 12474 E. 19th Ave.

Aurora, CO 80045

Report Date: August 7, 2015 Inspection/Testing Date: August 1, 2015

SET Project: 15-0801

Prepared by: Michael Schaan, WLS

Colorado Certified Asbestos Building Inspector, 18164

Certified Mold Inspector and Assessor

Limited Scope of Report

The mold inspection performed for client was a non-intrusive examination designed to identify suspect areas and conditions of the above-referenced primary building as it existed at the time of the inspection. Suspect conditions are those conditions defined by the Indoor Environmental Standards Organization (IESO) inspection standards having potential for mold contamination. The International Institute of Inspection, Cleaning and Restoration (IICRC) guidelines S520 are used to determine the appropriate Condition of the building materials on site and the remediation strategy. The inspection was limited to those areas that were visually and physically accessible. The inspection was not a risk assessment, physical inspection of systems, structure, or components of the primary building and its primary parking structure being inspected, as it relates to their serviceability. The inspection was performed in accordance with the Standards of Practice of the IESO and the IICRC in effect at the time of this Inspection. A copy of these standards is available upon request. This inspection is not intended to be technically exhaustive. The inspector has prepared this written Mold Inspection Report for the sole use and benefit of the client. The Mold Inspection Report shall identify, report, and make recommendation for future evaluation. Client agrees to read the entire Mold Inspection Report when received and shall promptly call the inspector with questions or concerns regarding the Report.

Purpose and Scope

The purpose of this assessment was to conduct a visual mold survey and to collect and evaluate the necessary samples in order to determine the presence or absence of mold and moisture within the subject affected areas and/or in the air. The scope of this assessment included a visual inspection of all affected areas in the subject property for visible mold and or water staining. Thirty-nine (39) Air Samples, Four (4) Wall Cavity Samples, and Five (5) Surface Samples were collected and analyzed by the Inspector. The results are incorporated into this report. Schaan Environmental Testing (SET) used a moisture meter and a Thermal Imaging Camera where necessary to identify any elevated moisture within the subject property’s building materials. The assessment was executed in accordance with the authorized scope of work. This report is solely a record of activities, observations, analytical results and recommendations performed to date.

Air Samples

SET considers an indoor space to have satisfactory fungal ecology based on the following criteria:

1. The total indoor concentration is less than the total outdoor control concentration. 2. The absence of water indicator mold types, in any quantity. 3. Visible suspect microbial growth (SMG) is not observed on any surface.

For brevity, the following office spaces did not indicate an elevated fungal concentration and will not be specifically addressed in this report. SET considers the following offices to have satisfactory indoor mold concentrations:

S09-118 S09-119 S09-116 S09-114 S09-115 S09-113 S09-110 S09-108 S09-106 S09-104 S09-136 S09-137 S09-138 S09-139 S09-140 S09-142 S09-141 East Stairwell S09-218 S09-219 S09-217-1 S09-216-1 S09-216 S09-212 S09-211 S09-213 S09-239 S09-240 S09-111 S09-103 S09-100 S09-207 S09-205

The following wall cavity samples are considered satisfactory: S09-219 North Wall S09-218 West Wall

The following spaces indicate an elevated fungal concentration in the air samples and are unsatisfactory:

West Stairwell (aspergillus/penicillium, paeciliomyces)

S09-117 (aspergillus/penicillium)

S09-112 (stachybotrys)

S09-216-2 (aspergillus/penicillium)

S09-217 (chaetomium) The following wall cavity samples indicate an elevated fungal concentration and are unsatisfactory:

S09-119 North Wall (aspergillus/penicillium, nigrospora)

S09-118 West Wall (aspergillus/penicillium) Room S09-117 is situated in the southwest portion of the first floor and houses several file cabinets. A 4” hole was noted in the southwest corner of this room and is open to the crawlspace.

Surface Samples

Visible mold was observed in the following crawlspace areas:

1. Small crawlspace under west stairwell – heavy growth on drywall and wood framing members.

2. Large crawlspace – heavy growth on joists and sub-flooring south of the small crawlspace. 3. Large crawlspace – sporadic growth, primarily on cross bracing between floor joists.

Inspector's Site Specific Recommendations

S09-117:

1. Close the floor penetration into the crawlspace. 2. Conduct air sampling to ensure asbestos fibers have not migrated out of the

crawlspace. 3. Erect containment and critical barriers to isolate this office from the remainder of

the spaces. 4. Place this room under negative air pressurization. Ensure the negative air machine

(NAM) is of sufficient capacity to provide a minimum of 4 – 10 air changes per hour. 5. Ensure workers wear the correct PPE to include full face respirators and disposable

suits and gloves. 6. Apply an anti-microbial solution to all surfaces inside the office containment area. 7. Thoroughly clean all surfaces inside the contained work area. Cleaning should

include ceilings, walls, floors, fixtures, and contents. 8. After all cleaning has been completed and in preparation for the post-remediation

verification inspection and sampling, allow the NAM to continuously operate for 24 hours.

9. After 24 hours of continuous operation, turn off the NAM. Do not allow access into the contained area. The air must rest for 24 hours.

10. After 24 hours of air rest, allow SET into the site to conduct post-remediation verification (PRV) sampling.

11. Refer to the following additional guidelines regarding mold remediation services.

S09-117 (Files): Reference: IICRC S-520: Standard and Reference Guide for Professional Mold Remediation SET classifies this room and its contents as a Condition 2 Environment (settled spores). Refer to Chapter 13 of the IICRC S-520 (Mold Remediation) standard. Several specific items from the standard are attached: Condition 1 (normal fungal ecology): 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.

Condition 2 (settled spores): 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 (actual growth): an indoor environment contaminated with the presence of actual

mold growth and associated spores. Actual growth includes growth that is active or dormant, visible or hidden

Paper Goods: Books, Documents, Manuscripts, Family Records, Scrapbooks, Photographs,

and similar items.

o Condition 2 - Porous contents with Condition 2 contamination are usually restorable using appropriate cleaning methods, based on material composition. Air washing can be effective. However, air washing should be performed only in a properly controlled work area, or using controlled techniques, where massive aerosolization will not pose a health risk to workers or occupants.

Valuable or irreplaceable documents that cannot be cleaned or decontaminated may be encased, laminated or otherwise sealed.

o Condition 3 - Porous contents with Condition 3 contamination are usually unrestorable, based on material composition. Cleaning may require a specialized conservation process, and might not be successful. Valuable or irreplaceable documents that cannot be cleaned or decontaminated may be encased, laminated or otherwise isolated.

Paper Goods: books, documents, manuscripts, family records, scrapbooks, photographs, and similar items

Most cleaning processes should start and end with HEPA - vacuuming.

Clean by HEPA-vacuuming and dry brushing or other surface cleaning method, while on a

downdraft cleaning table.

Air washing can be effective. However, air washing should be performed only in a properly

controlled work area, or using controlled techniques, where massive aerosolization will not pose a

health risk to workers or occupants.

Rapid drying after wet cleaning and appearance enhancement, as necessary, follows most

cleaning methods.

Valuable or irreplaceable documents that cannot be cleaned or decontaminated may be encased,

laminated or otherwise sealed

S09-112:

1. Investigate this room for the presence of a small or hidden water intrusion source. 2. Thoroughly clean all surfaces inside the office. Cleaning should include ceilings,

walls, fixtures, and contents. 3. HEPA vacuum and steam clean the carpet. Speed dry the carpet with carpet drying

fans.

S09-216-2: 1. Investigate this room for the presence of a small or hidden water intrusion source. 2. Thoroughly clean all surfaces inside the office. Cleaning should include ceilings,


fans.

S09-217:

1. Investigate this room for the presence of a small or hidden water intrusion source. 2. Thoroughly clean all surfaces inside the office. Cleaning should include ceilings,


fans.

West Stairwell: 1. Containment and negative air pressurization are already installed in this space. 2. Remove and discard vinyl flooring down to the wood sub-flooring. NOTE: This will require

asbestos abatement. 3. Starting at the floor, remove the lower 2 feet of the west and south walls. Continue with

wall removal to a point at least 2 feet beyond the last visible mold growth. Wall assembly removal will most likely require removal in adjoining offices S09-118 and S09-119.

4. Remove wall insulation from the west and south wall cavities in the same areas as where drywall/plaster were removed.

5. Apply an anti-microbial solution to all surfaces inside the containment area. 6. Thoroughly clean all surfaces inside the contained work area. Cleaning should

include ceilings, walls, floors, and fixtures. 7. Dry all impacted materials to a moisture content of at least 12%. 8. After all cleaning has been completed and in preparation for the post-remediation

verification inspection and sampling, allow the NAM to continuously operate for 24 hours.

9. After 24 hours of continuous operation, turn off the NAM. Do not allow access into the contained area. The air must rest for 24 hours.

10. After 24 hours of air rest, allow SET into the site to conduct post-remediation verification (PRV) sampling.

11. Refer to the following additional guidelines regarding mold remediation services.

Crawlspace: It is understood that the crawlspace contains asbestos. All work in this space should be performed by a Colorado asbestos certified and licensed contractor. 1. Erect containment and critical barriers to isolate the crawlspace from the remainder

of the structure. 2. Place the space under negative air pressurization. Ensure the negative air machines

(NAMs) are of sufficient capacity to provide a minimum of 4 – 10 air changes per hour.

3. Ensure workers wear the correct PPE to include full face respirators and disposable suits and gloves.

4. Remove and discard all drywall in the small crawlspace. 5. HEPA vacuum/wipe/sand as necessary to remove mold from wood framing

members. 6. Apply an anti-microbial solution to all surfaces inside the crawlspaces. 7. After all cleaning has been completed, allow the NAMs to continuously operate for a

minimum of 72 hours. 8. Refer to the following additional guidelines regarding mold remediation services.

Clearance Criteria The following criteria will be used to evaluate and assess remediation services: 1. All surfaces must be visually clean and free of mold. 2. All surfaces must not positively react with IAQ-1000, a strong hydrogen peroxide

solution, which indicates the presence of organic growth. 3. Surface samples must not contain mold in any quantity. 4. Air sample mold concentrations must be equal to or lower than the outdoor control

sample. No water indicator mold types can be in the indoor air sample. Even the presence of 1 water indicator mold type mold spore will cause the project to fail.

Remediation Protocol

A certified remediation contractor shall perform remediation under controlled conditions. The remediation contractor shall perform the work according to the guidelines and requirements specified in:

The accepted remediation practices of the Indoor Air Quality Association, IICRC S500 and S520.

The U.S.E.P.A. document, Mold Remediation in Schools and Commercial Buildings, March, 2001, EPA 402-K-01-001; and

Chapter 15 of the book Bioaerosol: Assessment and Control, 1999, by the American Conference of Governmental Industrial Hygienists.

1. General remediation specifications include as follows: All workers must wear proper protective gear at all times when doing mold and/or bacterial remediation in the subject property. Proper protective gear includes the following: 3M brand 6001 or equivalent full-face mask, hooded tyvec suit with built-in shoe covers, and construction grade rubber gloves.

2. The entire work area must be ventilated with negative air pressure and HEPA filtration during the remediation process.

3. Each area of known or suspected contamination must be thoroughly sprayed with a high pressure airless sprayer using an EPA approved disinfectant like IAQ1000, Sporicidin, Shock Wave or equivalent. The spraying should be allowed to dry naturally because the disinfectant kills while it is wet.

4. When treating visibly contaminated areas, the remediator must treat 2 feet beyond the contamination in each direction by spraying and removing the affected building product.

5. After demolition and removal of affected building materials, all remaining affected building materials (wood, green board and drywall surfaces) must have the remaining mold or bacterial staining removed by sanding, grinding, wire brushing or scraping. The sawdust or removed wood shavings must be vacuumed with a HEPA vacuum and the contents removed from the area by placing in a 6 mill plastic bag. The remediated area must be re-sprayed a second time with a high pressure airless sprayer using an EPA approved disinfectant as described in 4 above.

6. All contaminated building materials must be removed from the remediated area in 6 mill plastic bags.

7. No antimicrobial may be applied before the material to be treated is less than 28% moisture content as measured by a moisture meter.

8. All contents in the area under containment must be removed prior to demolition and remediation. Contents too large to remove must be cleaned as noted below and completely wrapped in plastic prior to the start of demolition.

9. All affected contents must be cleaned or replaced. These goods must be removed from the affected area after containment and negative air are in place.

10. All hard goods must be HEPA vacuumed and then wiped with an antimicrobial that will not damage the materials. Soft goods that need to be cleaned must be cleaned by soft goods and fabric specialists that use processes that will clean the entire item (typically this involves submerging in cleaning liquids).

11. All contents that are removed from containment must be sealed in 3 mil plastics bags or equivalent. These bags must be wiped down with antimicrobial prior to removal. Care must be taken to not cross contaminate traffic areas or other unaffected areas of the building.

12. The remediated area must be wiped down and HEPA vacuumed using the 5- step method before the final inspection and air assessment.

HEPA vacuum from the contaminated areas toward the HEPA air scrubber and /or negative air machine, allowing 15 minutes for the dust to settle.

Wet wipe with a disinfectant from the contaminated area toward the HEPA negative machine, allowing time for the dust to settle 15 min.

HEPA vacuum from the contaminated areas toward the HEPA negative air machine, allowing time for the dust to settle 15 min.

Wet wipe with a disinfectant from the contaminated area toward the HEPA negative machine, allowing time for the dust to settle 15 min.

Final HEPA Vacuum from the HEPA negative machine toward the remediation area exit. (Remember to always 5-step the polypropylene containment, micron sized particles will collect on the negatively charged surface.)

13. After the contaminated areas are cleaned, they can be sprayed with a non-pigmented antimicrobial like IAQ 6000 or equivalent.

14. Upon completion of the remediation work but before the antimicrobial coating is applied and the containment system is removed, the property must be inspected and sampled by an Indoor Environmental Professional familiar with the project who is independent of the remediation company in order to receive Post Remediation Verification.

Special Cases

If a moisture barrier or conditioned air system is required the following protocol must be followed: 1. Crawlspace conditioned air – if required. Install a continuous running exhaust fan to the outside and a

vent to provide conditioned air supply from the floor above. Exhaust fan must supply 1 ACH when crawlspace floor is covered by moisture barrier and the passive exterior vents blocked. For example, for a 1000 sq. ft. crawlspace with 3.5 feet between ground and floor deck, a fan should exhaust 58 cfm.. There must be one vent providing the supply of conditioned air per 250 sq ft of crawl space. Each vent requires a minimum of 3.6 sq. in. and maximum 4.4 sq. in. hole sizes.

2. Sealed moisture barrier installation when specified will be performed as follows. Use only materials equivalent or better than Ravines Industries, 15 mill polypropylene, ASTM #E1745 Class C Requirements. Double sealing all 3 foot overlaps with two sided approved tape, run the polypropylene 12 inches up the foundation walls, seal to wall using two sided tape and mechanical fasteners through C channel 2 foot on center. Cut and remove excess poly at the top of the C channel.

Background Debris Rating

Description Interpretation

0 No Particles Detected

No particles were observed on slide. The absence of particulates could indicate improper sampling, as most air samples typically contain some particulate

1Minimal non-microbial debris present.

Reported values are not affected by debris

2Up to 25% of the slide occluded with particulate debris

Particulate debris could mask the presence of spores but do not provide significant interference with the analyses

326 to 50% of the slide occluded with particulate debris

Particulate debris could mask the presence of spores and begin to interfere with the analytical count. As a result actual values could be somewhat higher than reported.

451 to 90% of the slide occluded with particulate debris

Particulate debris are heavy and would mask the presence of some fungal spores if present. As a result, the count could be higher than reported.

CBR Cannot Be Read

Sample could not be read due to excessive debris. Spores observed on the perimeter of debris are reported as present or abundant. The sample should be collected at shorter time interval or other measures taken to reduce the collection of non-microbial debris.

ANALYTICAL INFORMATION

Spore traps are a sampling devices that collect aeroallergens such as pollens, mold and fungal spores, fibers, dander, insect components and other air-borne contaminates. Samples are analyzed using light microscopy at 600X magnification with the entire sample trace or a percentage of the trace is counted. The results include both viable and non-viable fungal spores. This technique does not allow for the differentiation between Aspergillus and Penicillium spores. Small (1-3um) spherical fungal spores that cannot be identified and may included Aspergillus, Penicillium and Paecilomyces and others. Sample traces with greater than 500 spores per slide are difficult to count accurately due to overcrowding and should be considered estimations. Excessive non-microbial particulate debris can mask the presence of fungal spores, thereby reducing counting accuracies. All samples are graded with the following debris scale for data qualification.
