1.4 Submittals

A. Plan of Action.

1. The Contractor shall submit a detailed plan of the procedures they intend to use to comply with the regulations included in this specification. The plan shall include the location and layout of decontamination areas, the sequencing of asbestos work, the interface of trades involved in the performance of work, methods to be used to assure the safety of building occupants and visitors to the site, disposal plan including location of approved disposal site, sampling and testing, and a detailed description of the methods to be employed to control pollution. The plan must be approved by the Contracting Officer prior to commencement of work for conformance to these specifications.

B. Laboratory Qualification Information.

1. Submit proof of qualifications of testing laboratory and personnel. Accreditation by the American Industrial Hygiene Association (AIHA) for asbestos work and certification that persons counting the samples have been judged proficient by successful participation in the National Institute for Occupational Safety and Health (NIOSH) Proficiency Analytical Testing (PAT) Program shall be considered sufficient proof of compliance. Submittal must be approved by the Contracting Officer prior to beginning any testing.

C. Certificates of Compliance.

1. Submit certification that vacuums, ventilation, and other equipment required to contain airborne asbestos fibers conform to Federal, State and Local regulations.

1.5 regulatory requirements

A. The Contractor shall be responsible for obtaining approval for a waste disposal site in compliance with Section 61.25 of the EPA regulations.

B. The Contractor shall assume full responsibility and liability for compliance with all applicable Federal, State, and Local regulations pertaining to the protection of workers, visitors to the site, and persons occupying areas adjacent to the site. The Contractor is responsible for providing medical examinations and maintaining medical records of personnel as required by the applicable Federal, State, and Local regulations.

C. Asbestos Control Limits.

1. Inside Asbestos Work Area.

a. Air concentrations of asbestos shall not exceed an 8 hour time weighted average of 0.2 fibers (longer than 5 micrometers) per cubic centimeter of air. See 29 CFR 1910.1001.

2. Outside Asbestos Work Area.

a. Air concentrations of asbestos shall be maintained at an 8 hour time weighted average below 0.1 fiber (longer than 5 micrometers) per cubic centimeter of air. This applies to all areas in the building while work is in progress, except for the asbestos work area.

3. Final Clearance.

a. After final clean up, concentrations shall be below 0.01 fibers per cubic centimeters of air.

1.6 Project Conditions

1. The Ready Room Building was constructed in 1957. Based on a May 7, 1993 inspection report completed by John G. Feustel of Environmental Service & Technology, Inc., it was been determined that there is asbestos-containing materials in the drywalls of the ceiling and walls and in the tar and gravel of the roof. The roofing was replaced in 2005 and is now free of asbestos-containing materials.

B. Means of Egress.

1. Establish and maintain emergency and fire exits from the work area.

C. Use of Existing Facilities.

1. The Contractor may use electricity facilities in the building for project use only without charge. There is no water or sanitation facilities in buildings.

D. Access to Work Area.

1. Access to work area shall be through decontamination areas. The following shall have access to work areas:

a. Personnel properly trained and fully equipped for safety will be permitted in the work areas. (List by name).

b. Qualified State and EPA personnel will be permitted in the work areas.

c. Contracting Officer and designated representatives will be permitted in the work areas.

2. The Contractor shall provide protective clothing and respirators for the above listed personnel.

1. The wetting agent shall be 50 percent polyoxethylene ester and 50 percent polyoxethylene ether, in concentration of one (1) ounce in five (5) gallons of water.

3. EXECUTION

1.1 Preparation

A. Isolate the work area for the duration of the work according to acceptable trade practice and code requirements.

B. Build double barriers of plastic sheeting at all entrances and exits to the work area so that the work area is always closed off by 1 barrier when workers enter or exit.

C. Cover all floor, ceiling, and wall surfaces in the work area with 6 mil plastic sheeting taped securely in place to protect from damages.

D. Before the work is begun, clean all removable items and equipment. Remove them from the work area and store as directed.

E. Cover all nonremovable items and equipment in the work area with plastic sheeting taped securely in place.

F. Remove all heating, ventilation and air-conditioning system filters; pack them in sealable plastic bags (6 mil minimum) for disposal in the approved waste disposal site.

G. Post warning signs and labels as required by 29 CFR 1910.1001 and ASTM E849 and as directed by the Contracting Officer.

1.2 Monitoring

A. Monitoring of airborne concentrations of asbestos shall be in accordance with 29 CFR 1910.1001. Monitor the airborne concentration of asbestos before starting work to obtain a base line fiber concentration in the affected areas. Then monitor once every 4 hours during the work shift inside the asbestos work area, outside the entrance to the asbestos work area, and at the exhaust opening of the local exhaust system. If monitoring shows airborne concentrations causing excessive levels, notify the Contracting Officer immediately. In addition, monitor the airborne concentrations of asbestos after final cleanup and removal of the enclosure of the asbestos control area.

1.3 Site Inspection

A. While performing asbestos abatement work, the Contractor shall be subject to on-site inspection by agency officials. Work shall also be subject to inspection by OSHA and EPA inspector (and/or local building or health officials).

1.4 Demolition Procedure

A. The asbestos material shall be sprayed with water containing a wetting agent in the form of a fine spray. The material shall be sufficiently saturated to prevent emission of airborne fibers in excess of the exposure limits.

B. The asbestos material shall be removed in small sections. Before beginning the next section, the material shall be packed while still wet into sealable plastic bags and placed into drums for transporting.

C. Asbestos material around ducts may be removed using "glove bags."
