1.13 SCOPE OF WORK

A. This specification covers the abatement of asbestos from Two Pipes in the Heat Plant, from Vault #1 and Vault #2, and from Excavation #2 (and any associated below grade piping) at the project work site. It is the intent of the Contract Documents to show the work necessary to complete the project. The Asbestos and Lead-Based Paint Sampling Report (HDR, April 2013) along with its appendices shall be referred to along with this Specification.

B. The Contractor shall furnish all labor, materials, permits, notifications, insurance and equipment necessary for the total removal of all areas of ACM listed below and ACM debris associated with those portions of the project site. The Contractor shall visit the site to assess the exact amounts of ACM present as well as the extent of physical difficulty involved in its complete removal (Note: the piping in the Heat Plant reaches over 15 feet high and the Vaults and Excavation are below grade). The Contractor shall consult the General Removal Procedures and the General Description of Work below for the general intent of this Contract Document.

There will be a USAFA Representative (Air Monitoring Specialist) at the job site throughout all phases of the work.

1. Removal will be performed in four separate areas: two pipes in the Heat Plant, Vault #1, Vault #2, and Excavation #2 (and any associated below grade piping). Each area will be sealed off with 6-mil polyethylene critical containment barriers and will be under negative air.

2. For the two pipes in the Heat Plant, full containment shall be constructed including separate entry/exit and waste load areas, and will include a shower within the three chambered entry/exit area.

3. For the two Vaults and Excavation and any associated below grade piping that needs to be removed or renovated, entry/exit and waste load out will be conducted from one opening in each area due to the physical constraints of the below ground Vaults and Excavation. A mini-containment consisting of two chambers shall be constructed over the top of the man-hole of Vault #1 and Vault #2, and on top of the opening of Excavation #2.

A Centralized Worker Decontamination Area shall be provided at a location as close as practically possible to the two Vaults and Excavation. The decontamination area should consist of a wash area with a shower, soap and disposable towels.

The Contractor shall utilize wet methods, and HEPA vacuums for the removal of the following ACM:

a. Two Pipes in the Heat Plant: Pipe #1 (Closest to the door and stairway) and Pipe #2 next to Pipe #1

• An asbestos sample from Pipe #1 indicates 85% chrysotile asbestos.

The results indicate it should be assumed the gray wrap on both pipes contains asbestos unless proven otherwise. It should also be assumed the TSI of both pipes contains asbestos unless proven otherwise. All pipe wrap and TSI from areas to be disturbed on Pipes #1 and #2 shall be removed. Quantities shall be verified in the field.

• Refer to the HDR April 2013 Asbestos and Lead-based Paint Sampling Report for more sampling information.

b. Vault #1

ASBESTOS ABATEMENT 02080 - 10

• The black cementitious material around piping at wall penetrations contains 3% chrysotile asbestos.

• The black pipe wrap contains 4% chrysotile asbestos.

• It should be assumed all of the black cementitious material around all piping at the wall penetrations and all of the black pipe wrap in the vault contains asbestos. It should also be assumed if the same material is present on piping in piping tunnels or buried under ground, or is mixed in with debris on the floor, and/or is present in other vaults, it also contains asbestos unless proven otherwise. All like material in the vault and in piping tunnels that will be disturbed or removed shall be abated unless it is proven it does not contain asbestos. All quantities shall be verified in the field.

• Though the one floor debris sample did not indicate asbestos, asbestos debris is most likely mixed up in the soil, thus the entire soil surface should be considered as asbestos containing. All loose material/soil/debris shall be removed to a depth of at least 2 inches until no more visually suspect ACM is present or to a concrete surface. All quantities shall be verified in the field.

• Refer to the HDR April 2013 Asbestos and Lead-based Paint Sampling Re-port for more sampling information.

c. Vault #2

• Miscellaneous debris on the floor of the vault contains 3% chrysotile asbestos. This sam-ple was a composite of two random soil samples and the laboratory results describes the sample as “black resinous”, which is the same description as the pipe wrap. Asbestos debris is most likely mixed up in the debris on the floor, thus the entire floor surface should be considered as asbestos containing.

• The black cementitious material around the piping at the wall penetration contains 3% chrysotile asbestos.

• The black thick tar like pipe wrap near the pipe penetration contains 3% chrysotile asbes-tos.

• The entire floor surface of the vault should be considered as asbestos containing. All loose material/soil/debris shall be removed to a depth of at least 2 inches until no more visually suspect ACM is present or to a concrete surface. All quantities shall be verified in the field.

• It should be assumed all of the black cementitious material around the piping at the wall penetration, and all of the black thick tar like pipe wrap along with any of the same mate-rial on the floor contains asbestos. It should also be assumed if the same material is pre-sent on piping in piping tunnels or buried under ground, and/or is present in other vaults, it also contains asbestos unless proven otherwise. All like material in the vault and in pip-ing tunnels that will be disturbed or removed shall be abated unless it is proven it does not contain asbestos. All quantities shall be verified in the field.

• Refer to the HDR April 2013 Asbestos and Lead-based Paint Sampling Re-port for more sampling information.

ASBESTOS ABATEMENT 02080 - 11

d. Excavation #2

• Sample results indicate asbestos is not present in the black asphaltic pipe wrap.

• Sample results indicate asbestos is present (4% chrysotile) in a trace amount of material

(less than 1%) of black resinous material in the TSI on piping sample. The TSI itself (white fibrous plaster, 100% of the material) did not contain asbestos.

• It should be assumed all of the black resinous material around the piping contains asbestos.

It should also be assumed if the same material is present on piping in piping tunnels or buried under ground, and/or is present in other excavations or vaults, it also contains asbestos and if disturbed should be abated unless proven otherwise. All quantities shall be verified in the field.

C. The Contractor shall dispose of all ACM, asbestos debris and asbestos-contaminated debris in an EPA approved landfill in a safe and approved manner in compliance with all applicable Federal, State and local statutes, laws, rules, regulations and requirements, and provide the USAFA with records of the same. In the event procedural questions not covered by this job specification arise, the Contractor will be guided by the overall purpose of this section.

Intentional or willful violations of these job specifications will be grounds for immediate termination of the contract and possible assessment of damages.

D. The Contractor shall remove all ACM from the areas specified above and leave those areas of the site in a condition free of ACM and ACM debris.

See Attachment A – HDR April 2013 Asbestos and Lead-Based Paint Sampling Report.

Renovation plan drawings are included in the project plans.

If at any time during the specified scope of work the Contractor encounters any suspect ACM which have not been characterized by the Contract Documents, then the Contractor shall provide notice to the USAFA’s Representative.

E. General Removal Procedures

1. After constructing critical barriers with 6-mil poly, construction containment, obtaining negative air, and posting work areas with caution tape and OSHA notifications and barriers, the following general abatement procedures shall be utilized on the project:

a. Soil and Debris: Removal shall be performed with a HEPA vacumn and/or by wetting and scooping and bagging the soil/debris. Soil/debris shall be removed to a depth of at least 2 inches until no more visually suspect ACM is present or to a concrete surface.

b. Pipe Wrapping: Remove material using wet methods.

c. All ACM wastes generated shall be double-bagged, appropriately labeled, transported and disposed of at a Colorado-approved landfill. A manifest must accompany the ACM waste during transport and disposal.

ASBESTOS ABATEMENT 02080 - 12

d. Use proper worker protective equipment. Pass final visual clearance inspection. Apply lockdown encapsulant to all exposed surfaces. Pass final air clearance test (<0.01 f/cc- PCM). Remove remaining containment barriers and dispose of as ACM waste.

2. The Contractor shall conduct asbestos removal in accordance with the U.S. Department of Labor, Occupational Safety and Health Administration (OSHA) Standard 29 CFR

1926.1101 and the State of Colorado Regulation No. 8, Control of Hazardous Air Pollutants, Colorado Air Quality Control Division, Section III.

3. The USAFA’s representative will conduct air sampling within the regulated work area and air sampling of the perimeter of the work area.

4. Use proper worker protective equipment. Pass USAFA Representative’s final visual clearance inspection. Apply lockdown encapsulant to all exposed surfaces. Pass final air clearance test (0.01 f/cc - PCM). If the samples have results greater than 0.01 f/cc then additional PCM samples will be collected. The results of the additional samples must be less than 0.01 f/cc to clear the area. Remove remaining containment barriers and dispose of as ACM waste.
