CTG performs building inspections, abatement project oversight, management plans, and consultation. Prior to building renovations or demolition, the EPA requires that buildings are inspected to identify asbestos-containing materials (ACMs) prior to being disturbed. CTG also performs asbestos abatement oversight, which involves evaluations of the abatement contractor’s containment and work practices, daily area and final clearance air sampling, on-site PCM analysis and a detailed report documenting the significant events associated with the project. CTG employees are licensed by the State of Ohio in all asbestos disciplines.

Mold & Indoor Air Quality

CTG’s indoor air quality (IAQ) assessments include testing for defined parameters in representative complaint and non-complaint areas, and outside of the building for comparison. Measurements of general IAQ indicator parameters are performed to aid in evaluating general conditions (including comfort) and potential air contaminant sources which include temperature, relative humidity, carbon dioxide, and carbon monoxide. Sampling for airborne and surface microbial contamination is typically another component of the IAQ assessment.
