GENERAL DESCRIPTION OF REQUIREMENTS

This Scope of Work (SOW) is to provide pre-alteration assessment services to verify the location, quantities and condition of asbestos-containing material (ACM) and lead-based paint including lead containing material (LBP/LCM) in advance of building renovation, repair or construction work.

Additionally, services may also be needed to develop abatement design documents and provide independent 3rd party industrial hygiene surveillance and air monitoring of ACM and LBP/LCM removal projects.

General responsibilities include, but are not limited to: reviewing current project design documents concerning the extent of the alteration(s) and the existing survey or inventory reports for ACM and/or LBP/LCM, sampling and analyses of suspect materials for ACM and/or LBP/LCM presence, identification or verification of ACM and/ or LBP/LCM locations quantities and conditions in project areas, preparing ACM and/or LBP/LCM abatement project specifications and drawings, conducting pre-abatement meetings with the general and/or abatement contractor, performing visual inspections throughout ACM and/or LBP/LCM abatement projects, documenting daily abatement activities and compliance with the contract documents, interfacing with contractors and project personnel as necessary to ensure safe progression of work, collecting air samples before during and following ACM abatement projects, collecting similar air and surface wipe samples throughout LBP/LCM abatement projects, preparing and furnishing to GSA written reports covering one or more of the aforementioned responsibilities.

A sample statement of work is provided to further demonstrate typical project requirements and should be used as a guideline for determining which labor categories will be needed for service performance.

SAMPLE STATEMENT OF WORK:

SECTION 1 - ASBESTOS AND LEAD PRE-ALTERATION ASSESSMENT SERVICES:

1. The Contractor shall furnish all necessary labor, materials, supplies, equipment, supervision, and laboratory analyses to provide a pre-alteration assessment of asbestos and lead-paint, to include destructive testing and laboratory analyses as needed, in advance of renovation or construction work for federal office buildings in Orange and Los Angeles County. The main purpose of this Statement of Work (SOW) is to identify the presence, location, quantity and assess the condition of asbestos-containing (ACM), lead based paint and lead-containing materials (LBP/LCM) in the subject facility(s) prior to performance of any renovation or construction work. Ensure that all facility components located within a project space and / or potentially impacted by the upcoming renovation or construction work have been assessed for the presence of ACM and LBP/LCM.

This SOW will serve to support design efforts for estimating space alterations; to identify existing locations where ACM or LBP/LCM work is needed; and to provide the information required to continually update the building Facilities Asbestos Action Plan (FAAP). Detailed instructions are contained in Part 5 which is titled WORK REQUIRED AND REPORT PREPARATION. As a minimum, the following items need to be addressed in completing the SOW:

a. Review the current construction plans and the building’s existing asbestos lead-paint survey reports, laboratory results and related floor plan drawings. This includes the existing Facilities Asbestos Action Plan and any surveys and/or reports pertaining to repair and alteration or construction which may have affected the status of the asbestos.

This is to be accomplished in the offices of the GSA Facility Asbestos Control Manager (FACM), often the GSA Building Manager in charge of the buildings to be inspected. In some cases, visits to the buildings may be necessary to gain access to the building plans needed. NOTE: The existing FAAP may not be completely current or accurate. This document should be used as a baseline reference for conducting the assessment.

Materials previously identified as "ND" (none detected) or presumed, shall be re-

Do not remove this notice tested, as feasible.

b. Prepare a listing of ACM and LBP/LCM to be tested and assessed.

c. Specify project areas where destructive sampling would be needed to access potentially concealed ACM that would be affected by the project. As feasible, identify the types of potentially concealed ACM in such areas.

d. Contact the GSA Project Manager and/or FACM to arrange for the onsite assessment within the assigned buildings under the FACM jurisdiction. Discuss safety, health, and security consideration and ensure that the onsite GSA representatives are aware of all tasks and actions that will be needed to conduct the sampling and any destructive sampling and repair work as needed. Also arrange for government escorts or availability of keys and any other assistance needed from GSA.

d. Inspect all areas of the project space. This includes: mechanical areas, catwalks, return air plenums, crawl spaces, chases that can be accessed without demolition, adjacent areas occupied by tenants in the building, areas above all suspended ceilings throughout that can be accessed without demolition and building exteriors. Record all observed suspect materials in each discrete sampling area / functional space (FS) including captioned photo documentation of all of such areas and materials. Note: buildings with ACM/PACM fireproofing material require the establishment of mini-enclosures in order to lift out ceiling tiles/panels for inspection purposes. Refer to appended GSA Asbestos Technical Guide, Work Above Suspended Ceilings.

e. In inaccessible project areas potentially concealing ACM where no destructive sampling is permitted, contractor shall identify such areas in the report and indicate the type(s) and probability of concealed ACM or LBP/LCM. In such instances involving carpeting, carpets shall not be taken up to sample floor tile beneath the carpet. Inquiries shall be made, however, to determine the extent of coverage of suspect floor tile beneath the carpets. Any suspect floor tile must be shown on the CAD drawings and labeled as suspect but not assumed. Add a footnote that suspect material must be sampled prior to any disturbance or renovation of the material.

f. Visually inspect previously identified ACM and LBP/LCM and make note of current condition and quantities on the re-inspection form. Identify any existing conditions that could present general safety or health hazards.

g. Visually inspect each area for previously unidentified or un-sampled suspect materials.

h. Bulk sample any additional suspect materials identified during the inspection, in accordance with this Statement of Work.

• In addition to the assessment and sampling requirements presented in Part 3 of this Section, conduct functional space (FS) sampling for 1) carpeted areas that potentially conceal ACM where destructive sampling* is permitted; and, 2) drywall joint compound areas as follows:

o FS < 1,000 SF: Collect 3 random samples;

o FS 1,000 SF to 5,000 SF: Collect 5 random samples o FS > 5,000 SF: Collect 7 random samples

* Contractor must repair destructive sampling area by re-adhering carpet with an approved adhesive and patching affected drywall joint compound systems.

• As previously stated, in addition to carpeted areas, all areas that potentially conceal ACM where NO destructive sampling is permitted must be identified in the report as areas where ACM is suspected but not presumed to exist. Include a footnote that such areas

pg. 5

PROPERTY OF THE UNITED STATES GOVERNMENT

FOR OFFICIAL USE ONLY

Do not remove this notice need to be assessed and possibly sampled before any disturbance activities.

• If any suspect accessible material encountered in a project area cannot be sampled, contractor must include an explanation that describes the reason behind the sampling inability and the material shall be identified in the report as suspected but not assumed to be ACM. Include a footnote that such materials need to be assessed / sampled before any disturbance activities.

• For plaster samples, always state if the sample is common plaster or a special decorative, textured, or acoustical plaster. Also state whether the sample is from a wall, ceiling or somewhere else, such as an over spray of common plaster on a building column. A description only stating, “plaster” is unacceptable. A complete description would be “common ceiling plaster”.

• Plaster from one floor to the next, whether a common plaster or a special plaster, shall be considered a separate homogeneous area in buildings constructed prior to 1978. This applies even when the plaster from one floor to the next appears to be identical. The number of samples to be taken however is modified to be three per homogeneous area per floor.

• Report size, color, pattern, and/or other identifying characteristics when floor and ceiling tiles are sampled.

• When floor tiles are sampled, the associated mastics shall also be sampled. This also applies to ceiling and wall tiles anchored in place with mastic.

• Check cooling tower framework, louvered slats, and filler material and sample as necessary. Sample roofing materials when this can be accomplished without compromising the watertight integrity of the roof. If roofing materials cannot be sampled, the materials will be shown on the CAD drawings and labeled as suspect but not assumed. Add a footnote that suspect material must be sampled prior to any disturbance or renovation of the material. Other suspect materials to be sampled include various mastics and gaskets associated with piping, ductwork, and other mechanical system components. Also sample asbestos cement materials used in various structural applications.

• All samples shall be taken to the substrate and efforts made to preserve any layering of different materials. Report the contents of each layer including non-asbestos materials identified by the laboratory. When sample analytical results for layered systems (gypsum drywall with mud and joint compound) are provided for each separate layer and a composite result is provided, ensure that all other summary reports (for the same sample or homogeneous area) provide the same results for each layer, in addition to the providing the composite result.

• Should no destructive sampling be allowed for areas that potentially conceal ACM such as chases and the inside of walls, it shall be noted that they were not accessed and therefore must be evaluated before new renovation or demolition of such areas.

• Where possible, in occupied areas, sampling shall be in out-of-the way and out-of-sight locations to minimize the visibility of damage from the sampling.

• All reasonable precautions shall be taken during sampling to avoid or minimize the release of fibers into the air. Under no circumstances shall sampling be accomplished under conditions where the activity can be observed by building occupants.

• Accessible electrical insulation shall be inspected but not sampled. Suspect material found shall be reported.

• Sampling shall not be done that would compromise structural integrity or otherwise result in significant adverse effects on the function the suspect material is intended to perform.

• In building areas not routinely used by the building tenants such as mechanical rooms, above ceiling areas, etc., record the sample identification number at the sample repair spot using tape, or other appropriate material or on the piping or equipment surface by the sample location with an indelible marker or equivalent method.

• Sample identification numbers need not be recorded at the locations where surfacing material or miscellaneous materials are sampled.

i. Have all bulk ACM and LBP/LCM samples analyzed in accordance with these requirements.

j. For ACM materials, use the GSA asbestos survey spreadsheet template to record all materials identified in the survey. Include materials presumed to be asbestos but which could not be verified through sampling (e.g. fire doors, etc.).

Include materials tested and found to be non-asbestos containing on the spreadsheet.

k. Complete the appropriate DATA RECORD SHEET for each inspection area.

Ensure that all components of all mechanical systems; all insulated piping systems; all floor, wall, and ceiling materials; and all other miscellaneous suspect materials have been noted. Some DATA RECORD SHEETS are included at the end of this scope of work. Duplicate these for use as needed.

NOTE

If the Contractor has an in-house form normally used that provides all information required on the DATA RECORD SHEETS provided in this scope of work, the in-house form may be used.

l. For ACM materials, prepare a separate list of all damaged and significantly-damaged ACM.

m. For ACM materials, provide recommended response actions for materials found to be damaged and significantly damaged.

n. Prepare a final written survey report in accordance with paragraph five below. Reports for ACM shall include the completed GSA asbestos survey spreadsheet template.

o. For ACM materials, prepare a supplement to the current for the asbestos Operations &

Maintenance Plan (Facilities Asbestos Action Plan). The supplement must include updated floor plan that indicates sampling locations and type of ACM in the building.

Past information that is still current and applicable shall be noted.

p. For facilities with ACM fireproofing, resample and analyze bulk samples for to confirm the presence of ACM. Previous positive ACM sampling of fireproofing has been inconclusive.

q. Commonly found suspect ACM subject to pre-alteration assessments include, but are not limited to the following:

•Asbestos cement roofs •Asbestos cement pipes •Asbestos cloth •Asphalt roofing •Bitumen (adhesive and mastic) •Carpets and associated adhesives •Caulking •Cavity decking

3. Pre-alteration Assessment Requirements for ACM

ACM assessment shall be performed in accordance with the South Coast Air Quality Management District (SCAQMD) Rule 1403, and EPA AHERA guidelines [40 CFR Part 763 Subpart E, Section 763.85 9(b)] for ACM inspection, except as modified in this Statement of Work. The AHERA guidelines allow an inspector to assume that certain materials contain asbestos. In general, this Statement of Work does not; unless, the Contractor is told by the SPM not to sample, suspect material is not accessible, or sampling would destroy the critical integrity of the object (e.g. fire doors). LBP/LCM assessment shall be performed in accordance with 24 CFR part 35 (HUD) and 40 CFR part 745 .227 (EPA).

All suspect materials not previously identified as ACM or LBP/LCM or not previously sampled in accordance with current requirements must be sampled so that the number of samples meets this SOW. All destructive sampling locations must be repaired. Quantity of ACM samples collected shall follow AHERA guidelines, with a minimum of 3 per homogeneous material (friable and non-friable). Laboratory analyses of further bulk ACM and LBP/LCM bulk samples are not needed once the first homogeneous material sample tests positive for ACM or LBP/LCM.

LBP/LCM testing may include laboratory or on-site x-ray fluorescence (XRF) analyses.

a. Assessment activities accomplished under this SOW are intended to determine the current locations, quantities and condition of ACM and LBP/LCM on the project site and to obtain additional data as needed to develop project specifications and drawings for subsequent abatement. ACM data on the building must be sufficient to support design efforts for space alterations on the project site and/or for the building mechanical staff to safely perform maintenance work on the building mechanical systems. The data must also identify existing locations where ACM or LBP/LCM repair or abatement work is needed based on the damaged or significantly damaged current condition.

b. Prepare written schedules for site visits to be made prior to each field trip. Provide copies of the schedules to the Contracting Officer and to the GSA Project Manager.

Contact the GSA Project Manager to discuss the schedule and work out any problems. These schedules may require occasional revisions for some buildings due to temporary non-availability of GSA escort personnel or because of sensitive Government activities in the buildings to be inspected. The necessity for this shall be determined by the GSA SPM in charge of the buildings.

c. In addition to submittal of the schedules, personally contact the GSA Project Manager to coordinate the site visits. Verify availability of all assistance needed and contact the GSA Project Manager immediately if any delays or problems are encountered during the completion of the assessment.

Note: Failure to properly coordinate site visits with the GSA Field Office and Project Manager may result in failure to gain access to some areas because of security requirements. This would require additional visits to complete the inspections at no additional cost to the Government.

d. Review building plans, prior survey reports and related building information as needed to properly plan the assessment. This is to be accomplished in cooperation with the GSA Project Manager.

4. Abbreviations and Terminology:

Common abbreviations normally used in correspondence may be used when appropriate.

Terminology and the following abbreviations, specific to asbestos and asbestos survey reports, are also for use in the re-inspection reports. Use of any abbreviations or terminology not listed will require that a list of definitions be included in the reports.

CAD files are available, scanned manual drawings will be provided. Office and passageway layouts shown on these plans may not reflect the current configurations in the buildings. Please note if actual floor plan deviates from the CAD drawings provided. If room numbers differ from room identifications used by the surveyor, a footnote describing the difference is required.

Marked to identify locations of samples and presence of ACM and/or

LBP/LCM.

Develop Homogeneous Area CAD Drawings on a floor by floor basis.

Identify the location of all ACM and PACM on each floor drawing.

a. Always PROMINENTLY label drawings to indicate if the drawing is only the basic floor plan or indicate the type of ACM information shown.

EXAMPLE: “SECOND FLOOR VAT & TSI”.

b. Several drawings may be required for each floor, depending on the survey findings for a particular floor. Details are as follows:

(1) Basic floor plans.

• Show building columns.

• Show exterior walls and principal interior walls having slab-to-slab construction with heavier lines or some other means that will readily distinguish these from other walls and partitions.

• Show floor and room numbers. Room names may be used if there are no room numbers. In some cases, where room numbers are not shown at the doorway or entry way to a space, it may be necessary to check old drawings in the building mechanic’s office

pg. 13

PROPERTY OF THE UNITED STATES GOVERNMENT

FOR OFFICIAL USE ONLY

Do not remove this notice or in the GSA SP Manager’s office to find the room numbers.

• Show doorways and entryways.

• Show stairways, elevator shafts, and principal mechanical chases.

• Show the outlines of principal pieces of mechanical equipment in mechanical areas such as boilers, chillers, air handling units, and water tanks. Identify items shown including the equipment identification numbers (AHU #8, chiller #2, etc.) For complex mechanical areas, where this would badly clutter the drawing, provide a separate drawing or an insert on the basic drawing for the mechanical area.

• Provide a bar scale for distance and an indicator for the direction of North.

• Show complete building identification, the contractor’s company identification, and the date the drawing was completed.

2) Basic floor plans to which locations of TSI/ACM have been added.

These plans shall also show locations where bulk material samples were taken. Also indicate when the samples tested positive (+) or negative (-) for asbestos content. The TSI/ACM floor plans, in additional to the information indicated above, shall show the following:

• Locations of vertical pipe risers. As near as possible, identify wall and chase locations for floors where the pipes are known or suspected to be concealed and inaccessible inside of the walls and chases. This is important for future O&M and renovation work in the building.

• Locations of horizontal runs of pipe with ACM insulation outside of the mechanical areas. Do not show pipe runs outside of mechanical areas if the pipes have only non-ACM insulation.

• The numerous individual pipes inside of the mechanical areas do not have to be shown, with the exception of the vertical risers.

Ensure, however, that all piping in each mechanical area has been identified and that quantities are reported in the DETAILED

SUMMARY section.

• Show air ducts and boiler exhaust stack, inside of mechanical areas if insulated with ACM. Outside of mechanical areas, only show air ducts and boiler stacks that are insulated with ACM.

(3) Basic floor plans to which coverage by VAT and/or ACM mastic has been added. Indicate if only the mastic is ACM. These plans shall also show locations where the VAT and mastic samples were taken. Show coverage by suspect VAT that was not sampled because it is covered by carpet. Do not show coverage by floor tile and mastic confirmed to be non-ACM but do show where the samples were taken that confirmed these materials to be asbestos free.

(4) Basic floor plans to which locations and coverage by ACM textured/acoustical plaster; common wall and ceiling plaster that are

ACM; or other surfacing ACM have been added. These plans shall also show locations where bulk material samples were taken. If no

ACM plaster was found, only show sample locations. However, show even non ACM surfacing material on the drawings.

pg. 14

PROPERTY OF THE UNITED STATES GOVERNMENT

FOR OFFICIAL USE ONLY

Do not remove this notice

(5) Basic floor plans to which coverage by ACM suspended ceiling tile has been added. These plans shall also show locations where the bulk samples were taken. Show sample locations but do not show coverage by non-ACM Ceiling tile.

(6) In the reports, keep the plans for the same floor grouped together in the sequence given above.

(7) In cases where information on more than one type of ACM can clearly be shown without cluttering the drawing, then only one drawing may be used. If no ACM was found on a floor provide just one drawing (in addition to the basic floor plan) with a note prominently stating, “NO

ACM IDENTIFIED ON THIS FLOOR.”

(8) The footers showing building identification will not be shown since the building identification will be shown on the drawings. The page numbers, however, must be shown on each drawing and may be handwritten. CAD drawings for the reports do not have to be completed with the precision and detail that would be expected in engineering drawings however all details and information must be legible with the un-aided eye. They should however, be accurate enough for use in making area estimates or for approximating quantities of piping or other items for which measurements would be used.

8.5” x 11” drawings are preferred in the reports when this smaller size will not obscure details. However, 11” x 17” drawings will be acceptable if this would be beneficial in showing details. If 11” x 17” drawings are used, the report must be three-hole punched on the side to allow the drawings to fold out from a standard folder or three ring binders.

9. Photographs (as needed to facilitate identification or materials and/or conditions)

Photos should be labelled to identify materials, sample numbers and locations depicted or other unique identifiers as necessary.

10. ACM management plan (or FAAP) update

Edit existing FAAP to include currently identified ACM materials, their conditions, quantities and locations and associated recommended procedures for managing. Include recommended response actions for materials identified as significantly damaged.

Include footer on each page that includes: GSA building number, date and page number.

6. Pre-alteration Assessment Requirement for LBP/LCM

PURPOSE: The intent of the scope of work is to provide an accurate inventory of project-affected

LBP/LCM. A comprehensive destructive LBP/LCM survey is required before any demolition or renovation operations. As applicable, a pre-renovation/demolition LBP/LCM survey may use existing facility LBP/LCM survey data to the extent feasible and must supplement such data with assessments of any additional coated / painted materials that will be affected.

STATEMENT OF WORK: Perform intensive identification and location of lead containing materials scheduled to be affected by the project. Inspection and assessment should equal or exceed the intent of

HUD Guidelines. All coated / painted surfaces scheduled to be affected by the project should be evaluated. For example, materials evaluated should include all coated / painted window sills, walls, ceiling, doors, doorframes, molding, ceramic tiles, structural elements, etc.

X-ray fluorescence (XRF) may be used for general assessment and identification of LBP/LCM, but bulk paint chip sampling and laboratory analyses is required for any coating that was not identified to contain lead by the XRF method. The paint chip sampling and laboratory analysis is required to identify any lead content in affected components (i.e., lead containing material [LCM]) to allow for regulatory compliance associated with subsequent demolition, construction or renovation work.

A full report is required which should include floor-by-floor description of the types of materials sampled.

The overall format of the LBP/LCM assessment should be similar to the ACM final report. Positively identified materials should be highlighted, their approximate amounts determined and physical condition evaluated. For environmental liability recommendations cost estimates must be provided for abatement of all materials containing lead such as paints, ceramic tile and vinyl cove base molding as well as any other lead containing materials that have been determined to present an immediate hazard. This report must be broken down by current condition of each material, including all intact paint.

Lead Based Paint Definitions

The U.S. department of Housing and Urban Development (HUD) considers paint to be lead containing if the concentration is 1.0 milligrams of lead per square centimeter (1.0 mg/cm2) or greater or if the lead concentration is greater than 0.5% by weight. The Consumer Product Safety Commission

(CPSC) currently considers paint to be lead containing if the concentration of lead exceeds 90 ppm

(0.009%) by weight). In 1978, the CPSC banned the sale of lead based paint to consumers and its application to areas where consumers have direct access to painted surfaces. The Occupational

Safety and Health Administration (OSHA) does not recognize a minimum amount of lead in paint that precludes following OSHA lead construction standards.

Qualifications

1. Personnel must have a thorough working knowledge of all relevant federal, state and local regulations regarding lead based paint inspection, testing, preparation of Operations & Maintenance plans and construction standards. Candidates must have two years of experience and be certified and/or licensed to perform building lead based paint assessments when required by state law in the states where the buildings to be inspected are located. In California, persons must be Certified by the Department of Public Health for Lead Related Construction in the appropriate discipline (refer to definitions).Documentation of experience and certifications must be included with the proposal package.

7. ACM and/or LBP/LCM Abatement Project Design - Specifications and Drawings

a. Asbestos and/or lead related work must be incorporated into the scope of a project whenever such materials are affected by the project. The asbestos and lead project scope must be designed or reviewed by a qualified individual.

b. A person is qualified to prepare asbestos project designs once they have completed the 3-day EPA-approved MAP Project Designer course. In California, project designs may only be prepared by Certified Asbestos Consultants (CAC). The qualified person can either design the asbestos portion of a project or review the design performed by others.

c. A person is qualified to prepare lead abatement designs if they are certified by the California Department of Public Health as lead-related construction Inspectors Assessors and/or Project Designers. The qualified person can either design the lead abatement portion of a project or review the design performed by others.

d. Abatement project designs typically include marked-up architectural, mechanical, plumbing and other system affected drawings that delineate materials to be removed and/ or be affected; and, edited Master Abatement specifications sections that specifically address the materials to be removed and / or be affected.

SECTION 2 - PROJECT CONSTRUCTION PERIOD SERVICES AND MONITORING STATEMENT OF

WORK

The actual removal of ACM and/or LBP/LCM itself will be physically conducted by General Contractors/subcontractors as well as the containment set-up.

1. Asbestos and Lead Abatement Construction Administration

a. Review the current ACM and/or LBP/LCM assessment report for the building.

b. Review the ACM and/or LBP/LCM abatement project scope and drawings for the project.

c. Conduct / facilitate pre-abatement meetings with the general and/or abatement contractor.

d. Attend project meetings during active abatement work.

e. Review requests for information (RFI) and change order requests (COR) and assist GSA personnel with any related responses and/or contract modifications.

f. Manage and lead direct reports providing abatement monitoring and industrial hygiene surveillance.

2. Abatement monitoring and surveillance shall include, but not be limited to the following:

a. For ACM Class I and II abatement, collect background air samples in the abatement area before abatement setup.

b. Ensure that all project activities are conducted in accordance with the requirements of the contract documents.

c. Ensure all materials brought onsite by the contractor are approved for project use.

d. Perform daily frequent visual inspections throughout the abatement process. Include inspections of the abatement enclosures, barriers, methods and waste packaging. Enter the abatement project area at least once every four hours to observe ongoing removal activities.

e. Report on abatement activities to GSA personnel as necessary. Immediately notify GSA Project Manager of any unsafe conditions or acts conducted by the contractor.

f. Maintain a daily log of visual inspection findings and onsite observations concerning the contractor's compliance with abatement activities. This log shall be legible and made available upon request at all times to GSA personnel and appropriate local, State and federal agencies. A copy of the log shall be submitted to the GSA Project Manager at the completion of the project. . Refer to Appendix B Asbestos Abatement Compliance and IH Surveillance Checklist that summarizes typical regulatory

and GSA requirements that should be checked and documented as applicable (Note: Appendix B is intended as a tool to aid in evaluating asbestos abatement compliance and it is not required to be submitted with other required daily documentation).

g. For Asbestos Class I, II or III work, collect daily ambient air samples just outside the critical barriers or enclosures. Ambient air sampling areas should be free of potential sources / activities of air sampling bias.

I. Air samples shall be collected using high-volume air sampling pumps at fixed locations. Air sampling locations shall be within the general occupied building environment adjacent to the Class III work area(s). The air sampling cassettes shall be positioned at a height consistent with the breathing zone of a typical occupant. In accordance with NIOSH Method 7400, use sample collection filters which are 25 mm 8 micron mixed cellulose ester (MCEF) with extension cowl, open face. Sample volumes shall be sufficient to yield a sample result that will provide statistical confidence that the air concentration is at or below 0.01 f/cc. This calculation includes both the Limit of Detection, and the Limit of Quantitation achieved by fiber loading and laboratory quality control.

II. Air sample analysis shall be conducted by Phase Contrast Microscopy (PCM). Results of air sample analyses shall be provided during the work shift and no later than the end of the work shift during which the samples were collected.

III. Airborne ambient fiber levels are desired to be less than or equal to 0.01 f/cc.

IV. Should any ambient area air sample exceed 0.01 f/cc, apply the following:

• Class I and II Work: Notify GSA PM / point of contact as soon as feasible. Isolate immediate area and restrict access. Conduct surface cleaning in the affected area using HEPA vacuuming and / or wet methods. At completion of cleaning, collect additional sample(s) to achieve ambient airborne fiber level of < 0.01 f/cc. Repeat as necessary.

• Class III: Collect an additional confirmation sample. If confirmation sample is < 0.01 f/cc, no further action required.

• If confirmation sample is > 0.01 f/cc notify GSA PM / point of contact as soon as feasible.

Isolate immediate area and restrict access Conduct surface cleaning in the affected area using HEPA vacuuming and / or wet methods. At completion of cleaning, collect additional sample(s) to achieve ambient airborne fiber level of < 0.01 f/cc. Repeat as necessary.

V. Provide documentation that identifies the date of sample collection, location of samples, the start and stop times for each specific sampling pump, the volume of air sampled, the flow rate, pump calibration, calibration means and the name and certification of the Project Monitor.

c. At GSAs discretion, daily ACM samples exceeding 0.01 f/cc by PCM shall be re-analyzed by TEM and if found to be asbestos, shall require the abatement contractor to perform cleaning outside the enclosure. Cleaning shall be repeated until samples are below 0.01 f/cc or 70 s/mm2 by TEM.

d. Conduct final visual inspection following ACM and/or LBP/LCM abatement to verify all visible material is removed and surfaces are clean. Mark up copy of ACM and/or LBP/LCM assessment survey materials and areas that have been successfully abated. Marked up copy will be part of final report.

e. Conduct final air sampling for ACM and surface wipe sampling for LBP/LCM following successful visual inspection. Aggressive air sampling shall be performed for ACM clearance whenever feasible and provided such sampling won't result in an increased exposure risk to occupants outside the abatement area.
