SJRE was contracted by Colorado Pipe and Mechanical to perform a limited asbestos inspection within the State Capitol basement. This asbestos inspection was conducted on August 7, 2012 by a Colorado State Certified Asbestos Building Inspector. No asbestos was confirmed to be present in the basement; therefore, no further action was necessary. SJRE was also contracted to provide daily oversight, contractor compliance and air monitoring within the attic of the State Capitol from September 4, 2012 to September 11, 2012. The scope of work consisted of the identification and abatement of asbestos-containing thermal system insulation. SJRE provided abatement surveillance, pre/post-abatement inspections, laboratory analysis and perimeter air monitoring throughout the removal activities.
Under the supervision of SJRE staff, the abatement contractor performed class I abatement activities and the disposal of the ACM. Air samples were collected during removal activities to monitor the contractor’s performance during abatement. As per Colorado Regulation 8, since the negative air was exhausted to the interior of the building, it was monitored by SJRE’s on-site AMS. All air samples collected before, during, and after removal activities were analyzed by the on-site Industrial Hygienist using the PCM NIOSH 7400 Method.
At the completion of all removal activities and prior to collecting air samples for clearance, the Industrial Hygienist / Inspector conducted a visual inspection of the regulated work areas. Careful examinations of all areas within the containment, in addition to areas where debris and water could accumulate and be concealed, were thoroughly inspected. Final air clearance samples were taken and analyzed in-house, via PCM Method, by a SJRE AMS. SJRE ensured all clean-up activities were performed using the methods or more stringent methods than the guidelines provided in the Colorado Regulation No. 8, Part B, work practices.
