Guardian Building

Detroit, Michigan

TEC provided extensive environmental consulting services including comprehensive surveys of specific areas/floors throughout the building focused on the identification of asbestos-containing materials (ACM), lead paint and hazardous materials. The surveys were conducted to support the preparation of bidding specifications in advance of significant renovation activities. TEC identified ACM, lead paint and hazardous materials in building materials proposed for disturbance during renovation then completed building-specific survey reports.

Our scope of work also included development of detailed technical abatement specifications for the asbestos-containing materials to be removed by a licensed abatement contractor prior to renovation activities. We also developed a Lead Compliance Plan for Site specific guidelines for the demolition contractor to follow during demolition activities involving the disturbance of lead-containing paint per the OSHA Lead in Construction Standard. The hazardous materials survey involved evaluating light fixture ballasts and determining whether they contain PCBs. TEC inventoried the ballasts found on the site and contacted the manufacturers regarding their contents. This information was then summarized in tabular form. TEC also provided suggested work practices for the handling, labeling and disposal of both PCB-containing light ballasts and fluorescent light tubes. TEC presented the requirements for hazardous material removal and ACM abatement at a mandatory pre-bid meeting hosted at the Site. TEC collaborated with the project team to evaluate responsive bids and provide a recommendation for contract award.

This project also involved full-time on-site project supervision and air monitoring during pre-renovation abatement activities on various floors of this multi-story office building. On-site project supervision included verifying contractor engineering controls as specified, contractor personnel qualifications and abatement work practices. TEC conducted area and perimeter air sampling to verify the effectiveness of controls that were utilized. Upon completion of all site work, TEC prepared a final closure document, including air monitoring data, daily project summaries, regulatory agency notifications and waste disposal manifests.

TEC also performed a limited mold investigation of readily accessible, water damaged and/or mold-contaminated interior building surfaces in conjunction with the other environmental inspections and on the same floors of the building. TEC recommended the affected materials should be removed by a qualified mold remediation contractor. TEC developed the mold remediation scope of work and provided project oversight including tape lift sampling, bioaerosol air sampling and real-time particle count data collection to ensure compliance to the work plan and contractor thoroughness. The work was coordinated with the removal of other materials of environmental significance as part of the building renovation activity.
