| Exhibit A Project Date: June 4, 2004 Project Description: Assist a Industrial Hygienist firm in the source of interior moisture contributing to substantial amounts of interior mold growth on 50+ year old military apartment housing at a US Coast Guard Facility in Sonoma County. Interior moisture related to a number of current conditions, but not related to water entry through the exterior walls. The structure had recently been through a renovation process consisting of replacement with retrofit insulated windows and coating of the exterior stucco walls with an elastomeric coating system. The old windows were single glazed and leaked a lot of air. The elastomeric coating on top of decades of paint applications minimized the ability of the exterior walls to breath, where typically interior moisture travels through the walls as moisture vapor. The renovation processes inhibited air flow within the units, particularly the end units with large exterior wall areas. Excessive interior moisture coupled with tenants that have lots of furnishings, inhibited air movement on the interiors. Mold growth was noted behind furniture and within closets next to the exterior walls. Remediation consisted of the addition of mechanical ventilation within units to help circulate air, along with a tenant education system on how to minimize interior moisture build-up. 
Exhibit B Project Date: October 2004 Project Description: Incremental water tests were performed on this commercial services building for an East Bay Municipal Utility district. Historic infiltration had been occurring on this structure following conversion from a utility building to offices. Various exterior wall components, consisting of metal panels, aluminum windows, roofing and doors, were water tested independently of each other to track the sources of water infiltration. Once the testing was completed, the various building components were disassembled to determine the as-built construction and the methodology for repairs. Detailed drawings and repair specifications were produced along with bid documents to provide the building owners with materials to solicit competitive bidding. Project is ongoing and in the process of being bid for repairs.
Exhibit C Project Date: January 24, 2005 Project Description: Provided assistance to plastering contractor regarding water infiltration problems in a newly constructed office park in Solano Beach, California. Exterior building components consisted of cement plaster (stucco), masonry cladding, aluminum panel cladding, storefront window systems, and various aluminum cladding components. Water infiltration was noted through the masonry wall and plaster wall systems, which incorporate a cavity drainage system as opposed to the aluminum panels, which created a barrier system. The heavy reliance on aluminum reveals within the cement plaster allowed excess water into cavity drainage system.
Exhibit D Project Date: May 2005 Project Description: Assisted builder in identifying source of leaks within this church located in Hayward, California. Building was fairly new and was historically leaking adjacent to a few windows within the cement plaster clad walls. Isolation testing was performed to identify the source of the infiltration. Water was noted to be entering through the perimeters of the window frames at failed sealant joints. The sealants had not properly been bonded to the window substrate and in some instances the sealant joint was not sufficiently sized to allow for the proper sealant profile. Recommendations were made to inspect the sealants and to replace the caulking as necessary to keep water from accessing the outside perimeter of the window frames.
