1.0 BACKGROUND

Citadel Environmental Services, Inc. (“Citadel”), was contracted by the Veterans Administration San Diego Healthcare System (VASDHS) (the “Client”), to provide moisture consulting services in conjunction with a large scale moisture intrusion event impacting several areas on the west wing, Basement through Fourth Floor, of the Veterans Administration San Diego Medical Center (VASDMC), Building #1 (the “Building”).

Citadel conducted an initial emergency response assessment on August 7 and 8, 2015, after a fire sprinkler located inside the 4-West (4W) DLO Project Area was damaged just after midnight on August 7, 2015. The water from the flood traveled down to the lower floors via interstitial floor spaces (INT) to 3-West (3W), 2-West (2W), 1-West (1W), Stairwell 1 and the Basement Kitchen.

Citadel provided a summary of moisture measurements, observations and subsequent recommendations for remediation via a written report1, submitted via email on August 11, 2015.

Citadel was then asked by the Client to perform a follow-up moisture assessment of all affected areas on August 13, 2015. The objective of the follow up assessment was to document moisture levels of affected drywall materials and to ensure all affected areas were inspected and recommendations for remediation provided.

2.0 SCOPE OF SERVICES

Citadel Environmental Services, Inc. (Citadel) was contacted by Veterans Administration San Diego Healthcare System (VASDHS) (the “Client”) to provide moisture consulting services.

The scope of the investigation included:

1) Performing a follow up assessment, limited to impacted areas of 4W, 3W, 3W-INT, 2W, 2W- INT, 1W, 1W-INT and the Basement Kitchen, to document moisture levels and to inspect for visible signs of suspect microbial growth that may have developed in the 7 days since the moisture intrusion event occurred; and

2) Providing a written report to include all field documentation, moisture maps, photographic documentation, observations, methodologies and recommendations for the remediation.

Citadel’s Field Representative, Mr. Josh Hoover, conducted the follow up investigation from August 14 through August 31, 2015. Mr. Hoover is a California-Certified Site Surveillance Technician (CSST #14-5288). All work was performed under the general supervision of Ms. Michelle Campbell, an ABIH Certified Industrial Hygienist (CIH #10996 CP) and Certified Asbestos Consultant (CAC#09- 4519).

3.0 FIELD AND ANALYTICAL METHODOLOGY

Moisture Investigation

Citadel conducted visual inspections for signs of visible moisture damage and/or suspect microbial growth (SMG). The visual inspections were performed on August 14 and 17, 2015, and were limited to the following moisture-impacted areas of the Basement, 1W, 2W, 3W and 4W.

Citadel also conducted visual inspections of the 1W-INT, 2W-INT and 3W-INT floors.

In moisture-impacted areas, Citadel employed the use of a pin-type moisture meter (Delmhorst BD-2100) and a FLUKE® TiR infrared camera to check potentially impacted surfaces for relative moisture content. Materials were considered wet or impacted if their moisture content was greater than that of like materials from non-impacted areas of the building.

The Delmhorst uses two pin electrodes to detect differences in the capacitance of the signal to determine water content when the pins are inserted into the material so that they penetrate the surface of building materials. The FLUKE® TiR infrared camera is a non-contact device that detects infrared energy and converts the measurements to temperature readings. The camera then converts those temperature measurements into a thermal image on a video monitor which may also be saved as a jpg image.

The Delmhorst is designed to measure moisture levels in wood, concrete, EIFS, sheetrock, and other materials. It has a 6-40% moisture range for wood, a 0.2-50% range for gypsum and a 0 to 100 relative scale for all other non-wood materials. Regarding Sheetrock, readings below 0.5% indicate a dry condition, those between 0.5% and 1% correspond to borderline conditions, and readings over 1% indicate wet conditions. Elevated readings may represent ambient humidity, minor moisture intrusion, or the current status of a material previously wetted that has since partially dried out.

Interstitial Floor Spaces

In addition to assessing occupied areas of the VASDMC, Citadel conducted a walkthrough inspection of the interstitial floor spaces as follows: 1W-INT; 2W-INT, and 3W-INT. The following observations were noted:

3W-INT: No visible moisture using IR camera and no visible signs of SMG observed;

2W-INT: No visible moisture using IR camera and no visible signs of SMG observed; and 1W-INT: No visible moisture using IR camera and no visible signs of SMG observed.

General Recommendations for the Remediation of Moisture-Impacted Materials

The following recommendations pertain to the removal of moisture-damaged and/or microbial-impacted building materials:

Removal of moisture-impacted and/or microbial-impacted materials should be performed in accordance with standard industry practice (IICRC S500 Standard & Reference Guide for Professional Water Damage Restoration & IICRC S520 Standard & Reference Guide for Professional Mold Remediation), by an experienced remediation contractor, utilizing negative pressure containment(s).

Consult the VASDMC O & M Program to identify asbestos-containing materials and their location.

All asbestos removal operations shall be performed by a Cal/OSHA-DOSH-registered and California-licensed asbestos contractor. All disturbances of asbestos-containing materials, and/or abatement operations, should be performed under the surveillance of a third-party Cal/OSHA Certified Asbestos Consultant retained by the Client.

All disturbances of asbestos-containing materials, and/or abatement operations, must be performed in accordance with the Cal/OSHA requirements set forth in 8 CCR 1529. Given the location of the subject facility, all asbestos abatement must also be performed in accordance with San Diego Air Pollution Control District (SDAPCD) requirements.

Finally, notification of the presence and location of asbestos-containing materials shall be made to all employees and vendors who work within the VASDMC, in accordance with California Health and Safety Code, Section 25915, et seq. (also known as Connelly Notification Bills).

Please note that the actual scope of work is subject to change based on actual field conditions once intrusive work (removing drywall, etc.) is completed.

Contact Citadel for final visual inspection, air monitoring (asbestos) and swab sampling (sewage indicator organisms - as deemed necessary) prior to releasing areas for occupancy.
