HSA is well experienced in performing many types of investigations, including indoor air quality (IAQ) projects. Our background in IAQ includes innumerable projects, including small one day office investigations and multiple day evaluations of entire multi-story office buildings. These large projects have been completed for the City/County of San Francisco, the Cal-Trans Spring Street Building, and the recently completed IAQ project of the Los Angeles County Child Care offices in the former U.S. Borax Building. All of these large projects included evaluating multiple types of contaminants that may be present in an office building, including but not limited to: asbestos; volatile organic compounds; formaldehyde; particulates; PCBs; fungi; hydrogen sulfide; and legionnaires organisms. In each of these cases, HSA was able to identify causative agents and provide recommendations related to remediation of the worker complaints.
HSA has performed enumerable microbiological fungal investigations over the past 20 years. HSA is well experienced in the inspection for fungal colonization of buildings, both commercial and residential. HSA has performed these surveys for building occupants, building lessors, owners and managers, insurance investigations, and as part of construction defect litigation. HSA litigation support has encompassed both plaintiff and defendant cases.
All work is thoroughly reviewed and evaluated by a HSA Certified Industrial Hygienist with specific lead or asbestos certification, prior to making recommendations.
