microbial investigations

Stories of schools being evacuated because of mold-contaminated classrooms, or debilitating health claims by occupants of newly constructed buildings have been reported in our newspapers daily. Whether it is media hype, or valid concern, the issue of "toxic mold" is on the minds of everyone.  Monitoring for biological contaminants in the ambient air and on surfaces is not an easy task; each approach has its advantages and disadvantages.  Knowing when to use a cost-effective screening test or a full assessment to evaluate the presence and identity of mold in the indoor environment takes a thorough review of the factors involved.  Selecting the correct strategy requires the specialized skills, which senior staff members at The Cohen Group have developed from the hundreds of indoor environmental air quality assessments performed for building owners, their agents, developers, and construction specialists.  The Cohen Group utilizes sound scientific strategies for the recognition and characterization of the indoor environment for molds, bacteria and allergens.  The most difficult task is the meaningful interpretation of the results once the analysis has been completed.  Understanding the significance and limitations of the results is paramount for determining whether or not a potential hazard exists, and if so, what are the practical, feasible and cost-effective steps needed to eliminate the hazard.  The Cohen Group’s skills in selecting the appropriate monitoring tools and carefully evaluating the findings are second to none. If necessary, The Cohen Group will establish procedures for remediation of microbial hazards.

SUCCESS!

To maintain scheduling requirements, construction of the interior elements of a large, new high-rise building began before the exterior walls, roof and window systems were complete.  Due to water intrusion from winter rains, trash and ventilation shafts and perimeter wall cavities were significantly impacted with visible mold.  Construction was halted until a methodology for remediation could be developed.

The Cohen Group was retained to identify the locations and extent of water intrusion and mold growth in the building.  A strategy was developed to inspect each floor, collect samples to confirm suspect mold growth and, where needed, to develop a protocol for remediation.  The Cohen Group was asked to manage all aspects of the remediation project so that construction could continue during the remediation work.

Following a significant effort requiring daily contact with the owner, insurance representative, general contractor, and remediation contractor, The Cohen Group was able to confirm to the satisfaction of all affected parties that remediation was completed and that mold levels inside the building were no different than the outdoor environment.  The building was completed and is now occupied.
