ASBESTOS ABATEMENT

07/16

PART 1 GENERAL

Work outlined in this Section includes all work necessary for the removal and disposal of asbestos-containing materials (ACM) impacted during renovation/waterproofing and associated caulking abatement activities associated with the building. This work includes, but is not limited to, the removal and disposal of moisture barrier coating, caulking, and black floor expansion mastic and pressed board. The Contractor shall assume there is 1000 square feet of asbestos containing material within the abandoned coal vault that will need to be removed and properly disposed of.

It is suspected that the coal vault may have areas of Asbestos Containing Material (ACM) used to caulk joints in the walls and floor of the coal vault. It is the Government's intent to complete sampling and testing once the top of the structure is removed to determine appropriate handling and disposal if present. Work shall be sequenced to allow the Government to complete the sampling, testing and determination of appropriate follow on actions. It is estimated that this process will take 14 days (Amendment #1).

The Contractor shall be solely responsible for conducting this project and supervising all work in a manner that will be in conformance with all federal, state, and local regulations and guidelines pertaining to asbestos abatement.

3.2.1 Work Area Preparation

Where necessary, shut down electrical power, including receptacles and light fixtures. Under no circumstances during the decontamination procedures will lighting fixtures be permitted to be operating when the spraying of amended water may contact the fixture. Provide GFCI devices, temporary power, and temporary lighting installed in compliance with the applicable electrical codes. All installations are to be made by a State of Massachusetts licensed electrician. No wiring or electricity carry equipment compromised by damage, use or wear are acceptable for use on this project. Equipment will be immediately removed from service and the site by the contractor if directed by the Contracting Officer without compensation for replacement, loss of time or use.

Shut down and/or isolate heating, cooling, and ventilation air systems or zones to prevent contamination and fiber dispersal to other areas of the structure. During the work, vents within the work area shall be "criticalled" with duct tape and polyethylene sheeting.

3.2.2 Protection of Existing Work to Remain

Perform work without damage or contamination of adjacent work. Where such work is damaged or contaminated as verified by the Contracting Officer using visual inspection or sample analysis, it shall be restored to its original condition or decontaminated by the Contractor at no expense to the Government as deemed appropriate by the Contracting Officer. This includes inadvertent spill of dirt, dust, or debris in which it is reasonable to conclude that asbestos may exist. When these spills occur, stop work immediately. Then clean up the spill. When satisfactory visual inspection and air sampling results are obtained from the PQP work may proceed at the discretion of the Contracting Officer.

3.2.3 Furnishings

The Contractor shall be responsible for removing furniture from the work areas. The Contractor shall pre-clean moveable objects within the proposed work areas using HEPA vacuum equipment and/or wet cleaning methods as

Section 02 82 16 Page 22 appropriate and remove such objects from work areas and store in a location on site approved by the Contracting Officer.

3.2.4 Precleaning and Preparation

Pre-clean fixed objects within the work areas, using HEPA vacuum equipment and/or wet cleaning methods as appropriate, and enclose with a minimum 6-mil plastic sheeting sealed with duct tape. Do not use methods that raise dust, such as dry sweeping or vacuuming with equipment not equipped with HEPA filters

After HEPA vacuum cleaning, cover fixed walls with two layers of 4-mil polyethylene sheeting to the floor level. Where fixed walls are not used, two layers of 6-mil polyethylene sheeting will be applied to a rigid framework of wood, metal, or PVC. Where floor tile/mastic is not being abated, cover the floor with two layers of 6-mil polyethylene sheeting. All overlaps shall be sealed with tape or spray adhesive.

Clean and remove ceiling mounted objects, such as lights and other items not sealed off that interfere with asbestos abatement. Use hand-held amended water spraying or HEPA vacuuming equipment during fixture removal to reduce settled fiber dispersal.

3.2.5 Decontamination System

Construct the decontamination system with wood or metal framing, 3/8 inch sheathing and cover both sides with a double layer of 6-mil polyethylene sheeting, spray glued or taped at the joints. Caulk joints watertight at floor, walls, and ceiling.

Occupied areas and/or building space not within the work areas shall be separated from asbestos abatement work areas by means of airtight barriers.

The barriers shall be visually inspected several times daily to assure effective seal and the Contractor shall repair defects immediately.

3.2.5.1 Decontamination Enclosure

The Contractor shall establish contiguous to the work area, a decontamination enclosure consisting of an equipment room, shower room, and clean room in series. The only access between contaminated and uncontaminated areas shall be through this decontamination enclosure. If it is not feasible to set-up a contiguous decontamination unit, the Contractor shall establish a remote decontamination unit.

3.2.5.2 Access Between Rooms

Access between rooms in the decontamination system shall be through double flap curtain openings. The clean room, shower and equipment room within the decontamination enclosure, shall be completely sealed ensuring that the sole source of airflow through this area originates from uncontaminated areas outside the work area.

3.2.5.3 Equipment Decontamination Enclosure

The Contractor shall establish contiguous with the work area an equipment decontamination enclosure consisting of two (2) totally enclosed chambers

Section 02 82 16 Page 23 divided by double flap curtained opening. This enclosure must be constructed so as to ensure no personnel enter or exit through this unit.

3.2.6 Removal Procedures

The Contractor shall have a designated Competent Person on the job at all times to ensure establishment of a proper enclosure system and proper work practices throughout project. Abatement work will not commence until authorized by the Contracting officer. Proposed regulated areas for ACM abatement will be posted as required under 29 CFR 1926.1101, Communication of Hazards Section (k)

Spray asbestos materials with amended water using airless spray equipment or apply approved removal wetting agent to reduce the release of fibers during removal operations. The Contracting officer shall pre-approve the use of amended water as the wetting agent. In order to maintain indoor asbestos concentrations to the minimum, the wet asbestos must be removed in manageable sections. Material drop shall not exceed 8-feet. For heights up to 15-feet, provide inclined chutes or scaffolding to intercept drop.

Remove asbestos containing materials as appropriate by standard methods.

Fill disposal containers as removal proceeds; seal filled containers and clean containers before removal to equipment decontamination system. Wet clean each container thoroughly, double bag and apply caution label. Ensure that workers do not exit the work area thorough the equipment decontamination enclosure.

After completion of stripping work, all surfaces from which asbestos has been removed shall be wet brushed, using a nylon brush, wet wiped, and sponged or cleaned by an equivalent method to remove all visible material (wire brushes are not permitted). During this work, the surfaces being cleaned shall be kept wet.

Remove and containerize all visible accumulations of asbestos-containing and/or asbestos contaminated debris. During cleanup in the wet, utilize brooms, rubber dustpan, and rubber squeegees to minimize damage to floor covering. No dry sweeping is allowed instead use a HEPA filter equipped vacuum to clean debris on the floor and wet mop afterwards.

3.2.6.1 Sealing Contaminated Items Designated for Disposal

Sealed disposal containers, and all equipment used in the work area, shall be included in the cleanup and shall be removed from work areas via the equipment decontamination enclosure at an appropriate time in the cleaning sequence. All asbestos waste in 6-mil polyethylene disposal bags shall be double bagged in the equipment decontamination enclosure before removal from the site. Asbestos containing material shall be containerized while wet.

At no time shall asbestos material be allowed to accumulate or become dry.

Lower and otherwise handle asbestos containing material as indicated in 40

CFR 61-SUBPART M.

3.2.6.2 Contamination Outside Work Area

At any time during asbestos removal, should the Contracting officer suspect contamination of areas outside the work area(s), all abatement work shall stop until the Contractor takes steps to decontaminate these areas and eliminate the causes of such contamination. Unprotected individuals shall be

Section 02 82 16 Page 24 prohibited from entering suspected contaminated areas until air sampling and visual…
