Further suspect material sampling and <br />analysis will be conducted with potential increases in asbestos containing materials (ACM). If <br />additional ACM is found, Terracon anticipates an increase the abatement phase timeline. Terracon <br />will review copies of notices and submittals from the abatement contractor as forwarded from CH2M <br />Hill via the submittal process established for this project. <br /> <br />Abatement monitoring is required by the specification supplied by CH2M Hill. The specification <br />considered for review is Section 02 82 16.00 20 Engineering Control of Asbestos Containing <br />Materials for WP-42.C.1 and WP-42.C.2. <br /> <br />Terracon will provide a State of North Dakota accredited asbestos professional who will be on-site <br />for the duration of the abatement phase of the project. Terracon will be on-site to conduct pre- <br />abatement inspections of the work areas, containments, and waste storage locations prior to <br />abatement. Services provided by Terracon will follow the attached Scope of Services for WP-42.C.2 <br />– Park East Demolition Project (Scope) and WP-42.C.1 – Howard Johnson Hotel, Old Shakey’s <br />Pizza and Fargo Public Schools. <br /> <br />At the completion of abatement activities, Terracon will inspect the workspaces to confirm that <br />ACMs have been removed. Terracon will inspect work to ensure compliance with project <br />specifications as provided in the Scope. <br />Task 2 –Reporting: <br />Terracon will provide daily reports as requested including documentation of abatement activities <br />by the contractor and weekly summaries with estimated amounts of material removed. <br />Task 3 – Onsite Air Monitoring: <br />During the course of abatement, Terracon may randomly conduct ambient air monitoring for <br />asbestos outside the work areas. When requested or as scheduled, Terracon will collect no more <br />than five ambient air samples outside the work area during each day of abatement, per 10-hour <br />shift. Blanks will also be submitted to the laboratory for analysis. Terracon will also perform periodic <br />visual observations of the regulated work area for compliance with project specifications. Ambient <br />air samples collected during the project will be analyzed by phase contrast microscopy (PCM) in <br />accordance with the National Institute for Occupational Safety and Health (NIOSH) Method 7400 <br />Asbestos Fibers by PCM. Terracon will discuss issues that may arise with the abatement contractor <br />and coordinate with CH2M Hill as necessary to seek resolution. <br /> <br />When requested or as scheduled, Terracon will inspect the workspace to confirm that ACMs have <br />been removed as part of a companion walk through with the private qualified person (PQP).
