Specifications include, but are not limited to: This section includes all work necessary to reduce air concentrations of asbestos to the specified level and maintain the specified asbestos control limits during the life of the contract. It also includes removal, containment, and disposal of asbestos-containing materials (ACM).; 1. The Abatement Contractor shall carefully inspect areas listed in Appendix A; arrive at estimates of ACM to be removed; and determine the "work area" site conditions accessibility, "prepping" area requirements, and access routes to the facility.; 2. The Abatement Contractor shall be restricted to designated portions of the building and shall keep all equipment, vehicles and portable structures necessary confined to these designated areas.; 3. It is the Abatement Contractor's responsibility to leave the areas indicated in paragraph "Work Area" free of identified asbestos material.; 4. The Abatement Contractor shall submit with his bid the Scope of Work to remove the items in Appendix "A", based on his site survey. Each sub-item listed in Appendix "A" shall be addressed to insure that the Abatement Contractor has seen them all.; 5. The Abatement Contractor may have access to the work area during daylight hours. Contractor work schedules would have to be coordinated with the Owner and would be subject to his approval.; 6. Portions of the building will be occupied during the abatement process. The portion of the building that is under “abatement” will be under containment. The building is partitioned off to allow for continued operations in occupied areas of the building and the HVAC units are in separate zones.; 7. Owner will provide electrical power and water on-site.; Thermal System Insulation (T.S.I.) (approximately 7,958 linear feet) – Boiler 5 & 6: Demarcate a regulated area for any type of asbestos removal work, including full containment, RFCI, Splashguard, glove-bag, mini-containment, wrap-and-cut, and exterior abatement. All asbestos abatement removal will be performed using wet methods.; Full containment: Includes as a minimum: 6-mil polyethylene critical barriers, two 4-mil polyethylene layers on walls (where applicable), one 4-mil polyethylene layer on ceilings (where applicable), two 6-mil polyethylene layers on floors (where applicable), attached three-stage wet decontamination unit, and negative pressure ventilation system. The materials are to be removed by glove bag, manual and/or mechanical wet methods. Minimum PPE include full faced PAPR respirators with HEPA filter cartridges, gloves, rubber steel toe boots, hardhats and disposable suits; UNIT: A three (3) stage wet decon unit may be attached to the containment or a remote three (3) stage wet decon unit may be used near the work area. 6-mil poly is to be used as a walkway between the remote decon and the building to collect any possible ACM. The plastic walkway is to be disposed as ACM waste at the end of each day or more often as needed. The rinse water is to be filtered through a two stage (20 and 5) micron filtration system prior to discharge to the POTW. Figure 1 presents the typical decontamination unit.; WASTE DISPOSAL: 1. Collect wetted ACM into labeled bags then double bag air tight or sealed drums.; 2. Ensure that the ACM is adequately wet and properly labeled for disposal including name of project, generator, address, date and abatement contractor name.; 3. Remove deconned bagged waste through bag out unit and place in a secure container or rolloff.; 4. Ensure that the waste transporter and waste disposal site have been properly notified.; 5. Ensure that proper manifests accompany the waste.; VISUAL INSPECTION: After the ACM has been removed and general cleanup of the work area has been completed by wet wiping or HEPA vacuum, the Consultant and/or Project Manager with the Abatement Contractor Supervisor will conduct a walk through to establish that the work area is free of dust and debris. Post air clearance, a BPUB representative may preform a final walkthrough for personal documentation.; AIR MONITORING: Air monitoring will be conducted by the Consultant and/or the authorized Project Manager/Air Monitoring Technician including baseline, area and clearance using NIOSH 7400 methods (PCM). A minimum of three (3) baseline air samples inside work area are to be collected. Area samples are to be collected: one (1) representative area within the work area, one (1) at each negative air machine exhaust, one (1) outside of decon unit. After visual clearance has been achieved, three (3) clearance samples within the work area will be collected and analyzed. Upon achieving air clearance of less than 0.01 fibers per cubic centimeter, the containment may be removed.; PERSONAL AIR MONITORING: Air monitoring will be conducted by the Contractor in compliance with OSHA 29 CFR 1926 construction standard.
