Install other polyethylene barriers as required (floors, walls, ceilings, etc.). 9. Prior to removal, the Contractor shall lay 6-mil drop cloths in the basement below the Work Area. 10. Upon completion of a pre -abatement visual inspection by a representative of the Owner, removal of asbestos -containing material may begin, using appropriate techniques such as wetting and vacuum practices. At a minimum, the Contractor shall use full face Powered Air Purifying Respirators (PAPRs) for removal and cleanup work within the Work Area. If APRs are used, the Contractor must provide initial exposure assessment (IEA) to indicate that higher levels of respiratory protection are not required. This exposure documentation must be from similar projects and provide reliable expected values. If documentation is not provided which justifies the lesser protective APR, the Contractor must use higher levels of protection as required by OSHA. 11. Upon completion of removal of initial gross ACM and associated debris, the Owner's Representative shall conduct a visual inspection of the Work Area and collect measurements of soils depth. 12. The Contractor shall then be permitted to begin contaminated soils removal via truck -mounted vacuum system. 13. Properly seal, label and transport and dispose of all ACWM in accordance with applicable regulations. 14. Owner is not responsible for the Contractor's OSHA compliance monitoring. The Contractor shall post all air monitoring results on the site within 24 hours after collection of the sample(s). 15. The Contractor shall clean all surfaces after removal utilizing HEPA vacuuming and wet wipe methods. 16. The Owner will provide final visual inspection for all work areas and work Area Clearance for containments. Samples exceeding 0.01 f/cc will be deemed to have failed, and must be either analyzed by TEM (at the Contractor's expense) or the area re -cleaned and re -tested (to avoid scheduling and cost implications associated with TEM analysis unless otherwise specified by the Owner). 3.2 STOP ACTION LEVELS: A. Inside Work Area: The following applies to both personal and area air monitoring conducted within the Work Area. For Full Containments maintain an average airborne count in the work area of less than the Stop Action Level given below (to protect workers to 0.01 f/cc within the mask) for the type of respiratory protection in use. If the fiber counts rise above this figure for any sample taken, revise work procedures to lower fiber counts. If the Time Weighted Average (TWA) fiber count for any work shift or 8 hour period exceeds the Stop Action Level, stop all work except corrective action, leave pressure differential and air circulation system in operation and notify the Owner. After correcting cause of high fiber levels, do not recommence work for 24 hours unless otherwise authorized, in writing, by Owner. If 0.1 f/cc is exceeded, the Contractor shall install a secondary containment as described above prior to recommencing component removal activities. STOP ACTION LEVEL (r/cc) MINIMUM RESPIRATOR REQUIRED PROTECTION FACTOR 0.1 Half -face APR 10 0.5 PAPR 50 1.0 Supplied Air Pressure Demand 100 B. Outside Work Area: If any air sample taken outside of the Work Area exceeds the CDPHE Maximum Allowable Asbestos Level (MAAL), immediately and automatically stop all work except corrective action. The Owner will determine the source of the high reading and so notify the Contractor in writing. 1. Maximum Allowable Asbestos Level a. Air monitoring shall be conducted during normal occupancy and samples shall not be collected in an aggressive manner. b. Where PCM is used as the method of analysis the standard is 0.01 fibers per cubic centimeter of air (f/cc) which is equivalent to 10,000 fibers per cubic meter of air (Vin'). The NIOSH 7400 Method shall be used to analyze samples. The number of samples to be taken shall be determined by the air - monitoring specialist. Where TEM is used as the method of analysis, the standard is 70 structures/millimeter' (s/mm'). TEM analysis shall be conducted pursuant to the protocol in 40 C.F.R. Part 763, Appendix A to Subpart E (EPA 1995). C. All air monitoring collected for MAAL and Clearance purposes shall be performed by the Owner's representative who is independent of the abatement contractor to avoid possible conflict of interest. 2. In the event that airborne fiber levels outside a Work Area exceeds the MAAL when analyzed by PCM (when verified by TEM), the Contractor shall comply with CDPHE requirements for Major Asbestos Spills (Regulation 8 III.C.5.b). If the high reading was the result of a failure of Work Area isolation measures initiate the following actions: a. Immediately erect new critical barriers as set forth in Section 01526 Temporary Containments to isolate the affected area from the balance of the building. Erect Critical Barriers at the next existing structural isolation of the involved space (e.g. wall, ceiling, floor). b. Decontaminate the affected area in accordance with the Sequence of Events section of this section of the specifications. C. Require that respiratory protection as set forth in this section and applicable regulatory requirements be worn in affected area until area is cleared for re - occupancy. d. Leave Critical Barriers in place until completion of work and ensure that the operation of the pressure differential system in the Work Area results in a flow of air from the balance of the building into the affected area. e. If the exit from the clean room of the personnel decontamination unit enters the affected area, establish a decontamination facility consisting of a Shower Room and Changing Room as set forth in Section 01563 Decontamination Units at entry point to affected area. f. After Certification of Visual Inspection in the Work Area remove critical barriers separating the work area from the affected area. Final air samples will be taken within the entire area as set forth in Section 01712 Work Area Clearance. In the event that areas beyond the work area become contaminated with asbestos, asbestos -containing dust/debris, and/or visible emissions from the work area, the Contractor shall be responsible for all costs associated with cleaning and subsequent testing (visual inspection, air sampling and bulk analysis) of these areas. If the high reading was the result of other causes initiate corrective action as required by the Owner. C. Effect on Contract Sum: Complete corrective work with no change in the Contract Sum if high airborne fiber counts were caused by Contractor's activities. The Contract Sum and schedule will be adjusted for additional work caused by high airborne fiber counts beyond the Contractor's control. Contractor is responsible for all costs associated with TEM verification where PCM samples exceed 0.01 f/cc, and any subsequent cleaning and additional sampling costs. 3.3 STOP WORK: A. If the Owner presents a written stop work order, immediately and automatically conform to that stop work order, while maintaining temporary containments and pressure differential. Do not recommence abatement work until authorized in writing by Owner. B. Immediately initiate the following actions: After being presented with a stop work order immediately: 1.
