$60,000 in the Specially Funded Capital Projects Fund, Hanger 5N Demolition Meacham

6. Authorize the City Manager to execute a contract with Targa, Inc. for the demolition of Hangar 5N
for$68,390 and a completion time of 30 calendar days.
DISCUSSION:
The project consists of removing the 28,000 square foot metal hangar and concrete floor slab along
with all underground utilities and sumps. The area will be secured by installing a fence to replace the
west face of the hangar. The Environmental Management Department will conduct an asbestos
abatement on the property at a cost of$18,490.
The removal of the hangar is necessary because the building has out-lived its usefulness and to open
the site for redevelopment. On June 6, 2000, the City Council directed that the hangar be removed.
The project budget is as follows:
Demolition $49,900
Contingency 6,000
Construction Management 4,100
Abatement 18,490
Total $78,490

equipment and tools before final air clearance sampling in each work area.
1.1.3.2 Removal of Asbestos Transite:
The cement asbestos transite will be removed with minimal breakage utilizing hand tools and
workers equipped with a safety harness attached to a lifeline. The Contractor will be required to
adhere to applicable fall protection requirements in accordance with OSHA 29 CFR 1926.500,
502 and 503. A 6 mil thick polyethylene ground cloth will be established at a minimum distance
of ten feet around the perimeter of the work area prior to ACM removal activity. Any asbestos
containing roof shingle debris in the work area should be adequately wetted and removed prior
to establishing the perimeter ground cloth barriers.
Scaffolding or a powered platform lift will be used to access the roof to complete the work. If
scaffolding is used, all applicable OSHA regulations must be followed in accordance with 29
CFR 1926.451.
Summary of Abatement Work
The Contractor should conduct the removal beginning at the parapet wall and working down
r
towards the eaves of the building. Work procedures for the ACM removal are detailed in
Section 2.2.3: REMOVAL OF CEMENT ASBESTOS ROOF SHINGLES. The cement asbestos
transite will be kept wet and removed as whole components to the best extent possible in order
to reduce potential airborne fiber emissions. Portable 5-gallon Hudson sprayers or equivalent
will be used to apply the amended water for the work.
The cement transite will be placed in appropriate disposal bags, labeled and sealed tightly. The
Contractor will lower the ACM and ACE to the ground in labeled 6 mil plastic disposal bags
using a platform lift or manually with a rope or cable. Under no circumstances will the ACM
be dropped or thrown from the roof to the ground.
Personnel Protection and Decontamination
Respiratory protection will require half-face dual cartridge air purifying respirators during ACM
removal operations.
Asbestos Abatement Page 2

Asbestos Abatement - Hanger #5, City of Fort Worth, Texas
' Abatement workers wearing half-face respirators will be required to wear safety glasses and
gloves during the work. Hard hats, safety shoes and safety glasses will be required for all
personnel entering the work area below the roof line.
The Contractor will have the option of two (2) personal decontamination procedures as follows:
Option 1
The abatement workers will wear two (2) disposable protective coveralls and utilize a remote
two-stage dry decontamination procedure utilizing a portable HEPA vacuum and washing
exposed skin surfaces such as hands, face and neck prior to exiting the work area.
Option 2
The abatement workers will wear a single disposable protective coverall and utilize a remote
three-stage wet decontamination unit with a working full-body shower unit and filtration system.
After the ACM has been removed and the work area cleaned, a detailed visual clearance
inspection will be conducted to determine if ACM or asbestos contaminated elements (ACE)
remain prior to final clearance and work completion. OSHA personnel and area monitoring will
be conducted with analysis by (PCM).
1.1.3.3 Removal of Asbestos Floor Tile and Mastic:
The Contractor shall remove only damaged asbestos floor tile in the work area. The damaged
floor tile will be removed in whole pieces where practical. The non-friable mastic will not be
removed.
Critical barriers shall be established over all openings into the work area. ACM debris should be
adequately wetted prior to establishing perimeter critical barriers. The containment must be
structurally sound so that it shall not collapse under negative pressure and work conditions. A
structurally unsound containment design shall not be accepted. Primary barriers for full
containment shall consist of two (2) layers of 4 mil polyethylene sheeting for the walls securely
anchored from the floors to the ceiling. Polyethylene sheeting shall meet fire rating
requirements and ASTM requirements in accordance with TDH regulations. A three-stage, wet
decontamination unit with air-lock barriers shall be erected for worker entrance and exit into the
work area of the containment.
The Contractor must establish negative air into the containment and maintain a pressure
differential of -0.02 inches of water. See specification drawings enclosed for the material
location and the project design. The following requirements must be followed in areas where a
pressure differential of-0.02 inches cannot be established:
A. A negative pressure enclosure (NPE) must be used where the configuration of the work
area does not make erection of a full containment enclosure feasible.
B. The negative pressure enclosure may be of any configuration.
C. At least 4 air changes per hour is to be maintained in the NPE.
D. The NPE must be kept under negative pressure throughout the period of its use, and
E. Air movement must be directed away from employees performing asbestos work within
the enclosure, and toward a HEPA filtration system.

F. A competent person must supervise all work and be licensed in Texas, as an asbestos
supervisor.
A modified containment design may be used in lieu of a full containment for small removal ■
areas. If a modified containment is used, a dry decontamination unit will be allowed in
accordance with the procedures for transite removal in this specification.
RFCI methods may be used if only a few floor tiles are removed. The Contractor will be
required to be trained in the method and a copy of the RFCI guidelines must be on-site during
removal. '
After the ACM has been removed and the work area cleaned, a detailed visual clearance
inspection shall be conducted to determine if ACM or asbestos contaminated elements (ACE)
remain prior to final clearance and work completion. OSHA personnel and area monitoring shall
be conducted with analysis by PCM. Final air clearance in the area shall be conducted using

1.1.4. CONTRACTORS USE OF PREMISES:
Cooperate fully with the Owner's representative to minimize conflicts and to facilitate Owner's '
safe and smooth usage of buildings. Perform the work in accordance with specifications,
drawings, and phasing plan.
Use existing facilities in building strictly within the limits shown in contract documents and the
approved pre-abatement plan of action. Asbestos Abatement specification drawings show the
limits of containment, project design and the placement of the decontamination facilities for
workers and equipment. Variations from the arrangements shown on drawings will be secured
in writing from the Owner's through the pre-abatement plan of action.
1.2. DIFFERING SITE CONDITIONS:
The quantities and location of ACM indicated on the drawings and the extent of work included
in this section are only best estimates which are limited by the physical constraints imposed by
occupancy of the building. Accordingly, minor variations (+ 15%) in quantities of ACM within
the limits of containment for each abatement stage are considered as having no impact on
contract price and time of this contract. Locations of ACM different than indicated on drawings
but within the limits of containment are considered as having no impact on contract price and
time of this contract.

head covers, and clean respirators, then proceed through shower room to equipment room, and
put on work boots.
1.8.5. DECONTAMINATION PROCEDURES:
Require all workers to adhere to the following personal decontamination procedures whenever
they leave the work area of a full decontamination unit:
Require that all workers use the following decontamination procedure as a minimum
requirement whenever leaving the work area:
Dry Decontamination with double layer of protective clothing:
1. Prior to exiting work area, HEPA vacuum all visible debris on the outer coveralls with
special attention to neck and foot areas. Remove outer layer of disposable coveralls
and proceed to second stage decontamination area.
2. Still wearing respirator, remove second layer of coveralls and all other clothes disposable
head covers, and disposable footwear covers or boots. Thoroughly wash hands, face,
neck and any other skin surfaces exposed during work.
3. Remove, clean and enclose respirators within a sealed bag or container in the
equipment room.
Remote Wet Decontamination:
1. When exiting work area, remove disposable coveralls, and all other clothes disposable
head covers, and disposable footwear covers or boots in the equipment room.
2. Still wearing respirators, and completely naked proceed to showers. Showering is
mandatory. Care must be taken to follow reasonable procedures in removing the
respirator to avoid asbestos fibers while showering. The following procedure is
required as a minimum:
a. Thoroughly wet body including hair and face. If using a Powered Air-Purifying
Respirator (PAPR) hold blower unit above head to keep canisters dry.
Asbestos Abatement Page 19
Asbestos Abatement - Hanger#5, City of Fort Worth, Texas
b. With respirator still in place thoroughly wash body, hair, respirator face piece, and all
parts of the respirator except the blower unit and battery pack on a PAPR. Pay
particular attention to clean seal between face and respirator and under straps.
c. Take a deep breath, hold it and/or exhale slowly, completely wet hair, face, and
respirator. While still holding breath, remove respirator and hold it away from face
before starting to breath.
3. Carefully wash facepiece of respirator inside and out. If using PAPR: Shut down in the
following sequence, first cap inlets to filter cartridges, then turn off blower unit (this
sequence will help keep debris which has collected on the inlet side of filter from
dislodging and contaminating the outside of the unit). Thoroughly wash blower unit and
hoses. Carefully wash battery pack with wet rag. Be extremely cautions of getting
water in battery pack as this will short out and destroy battery.
4. Shower completely with soap and water.
Rinse thoroughly.
5. Rinse shower room walls and floor prior to exit.
6. Proceed from shower to Changing Room and change into street clothes or into new
disposable work items.
1.9. NEGATIVE PRESSURE FILTRATION SYSTEMS:
The Asbestos Contractor will provide enough HEPA filtered negative air units to completely a
exchange the work air 4 times/hour. Contractor will demonstrate the number of units needed
per work area for 4 room air changes by calculating the volume flow rate (cfm) delivered by
each unit under 2" pressure drop across filters. Provide at least one standby unit in the event of
a machine failure or emergency such as contamination in surrounding nonwork area. When a
pressure differential system is selected provide enough HEPA filtration units to filter and
recirculate the air in the work area at a rate of 4 room air changes per hour.
1.9.2. NEGATIVE AIR MACHINES (HEPA UNITS)
(See Appendix J, EPA 560/5-85-024, Guidance for Controlling Asbestos-Containing Materials in
Buildings). The requirements listed above will be utilized for this project.
1.9.3. PRESSURE DIFFERENTIAL:
Provide a fully operational negative air system within the work area continuously maintaining a
pressure differential across work area enclosures of-0.02 inches of water. Demonstrate to the
Owner's representative the pressure differential by use of a pressure differential meter or a
manometer, before disturbance of any asbestos containing materials. This pressure differential
will be used for either negative air system or pressure differential system.
1.9.4. MONITORING:
Continuously monitor and record the pressure differential between the work area and the
building outside of the work area with a monitoring device incorporating a strip chart recorder.
Make the strip chart record part of the project log.
Asbestos Abatement Page 20
Asbestos Abatement - Hanger#5, City of Fort Worth, Texas
9.9.5. AUXILIARY GENERATOR:
If necessary, a generator will be used to supply electrical power to the job site. Operate
generator in accordance with all OSHA safety regulations. Generator will be operated so that
exhaust does not enter the building.
9.9.6. SUPPLEMENTAL MAKEUP AIR INLETS:
Provide where required for proper air flow through the work space in location approved by the
Owner's representative by making openings in the plastic sheeting to allow air from outside the
building into the work area. Locate auxiliary makeup air inlets as far as possible from the
exhaust unit (e.g., on an opposite wall), off the floor (preferably near the ceiling), and away from
barriers that separate the work area from occupied clean areas. Cover with flaps to reseal
automatically if the negative pressure system should shut down for any reason. Spray flap and
around opening with spray adhesive so that flap seals if it closes.
9.9.7. USE OF SYSTEM DURING ABATEMENT OPERATIONS:
Start exhaust units before beginning work (before any ACM is disturbed). After abatement work
has begun, run units continuously to maintain a constant negative pressure until
decontamination of the work area is complete. Do not turn off units at the end of the work shift
or when abatement operations temporarily stop.
Do not shut down negative air system during abatement operations procedures, unless
authorized by the Owner's representative in writing.
Start abatement work at a location farthest from the exhaust units and proceed toward them. If
an electric power failure occurs, immediately stop all removal work and do not resume until
power is restored and all exhaust units are operating again.
At completion of abatement work, allow exhaust units to run as specified under this section, to
remove airborne fibers that may have been generated during abatement work and cleanup and
to purge the work area with clean makeup air. Units may be required to run after
decontamination, if dry or only partially wetted asbestos material was encountered during any
abatement work.
9.9.8. DISMANTLING THE SYSTEM:
When a final inspection and the results of the final air tests indicate that the area has been
decontaminated, exhaust units may be removed from the work area. Before removal from the
work area, remove and properly dispose of pre-filters, and seal intake to the machine with 6 mil
polyethylene to prevent environmental contamination from the pre-filters.
1.10. CONTAINMENT BARRIERS AND COVERINGS OF WORK AREA:
9.90.9. GENERAL:
Seal off perimeter of work area to completely isolate abatement areas and to contain all
airborne asbestos contamination created by abatement work. Cover all surfaces of the work
area to protect them from cross contamination, to facilitate more efficient cleanup, and to
protect the finishes from the asbestos abatement work. Should the area beyond the seal off
Asbestos Abatement Page 21
i
Asbestos Abatement - Hanger#5, City of Fort Worth, Texas
limits become contaminated as a consequence of the work, clean those areas in accordance
with procedures described in this section at no additional cost.
1.10.2. PREPARATION PRIOR TO SEALING OFF:
Place all tools, staging, etc. necessary for the work in the area to be isolated prior to erection of
temporary plastic sheeting enclosure. Disable ventilating systems or any other system bringing
air into or out of the work area. Disable system utilizing positive means that will prevent
accidental premature restarting of equipment, i.e., disconnecting wires, removing circuit
breakers, lockable switch, etc.
1.10.3. CONTROL ACCESS TO WORKAREA:
Permit access to the work area only through the PDF. All other means of access will be closed
off and sealed and warning signs displayed on the clean side of the sealed access. Where the
work area is immediately adjacent to or within view of occupied areas, provide a visual barrier of
opaque polyethylene sheeting at least 6 mil in thickness so that the work procedures are not
visible to building occupants. Where the area adjacent to the work area is accessible to ,the
public, construct a barrier of plywood or other suitable material at least 8 feet in height that is
able to withstand the negative pressure as specified.
Post warning signs at each visual and physical barrier per OSHA requirements. Alternate
method of containing the work area or different definition of the limits of seal-off from the one
shown on the drawings may be submitted to the Owner's representative for approval in
accordance with this section. Do not proceed with any such alternatives without prior written
approval by the Owner's.
1.10.4. CRITICAL BARRIERS:
Completely separate the work area from other portions of the building, and the outside by sheet
polyethylene barriers at least 6 mil in thickness and sealing with duct tape. Individually seal all
ventilation openings (supply and exhaust), lighting fixtures, doorways, windows, and other
openings into the work area with duct tape alone and with polyethylene sheeting at least 6 mil in
thickness, taped securely in place with duct tape. Maintain seal until all work including project
decontamination is completed. Take care in sealing off lighting fixtures to avoid melting or
burning of sheeting. Provide sheet plastic barriers at least 6 mil in thickness as required to
completely seal openings from the work area into adjacent areas. Seal the perimeter of all
sheet plastic barriers with duct tape or spray cement.
1.10.5. PRIMARY BARRIERS:
When the asbestos will be removed within a full containment design, two (2) layers of 4 mil
polyethylene sheeting for the walls, and two layers of 6 mil polyethylene sheeting for the floor
unless floor the is to be removed. If floor the is to be removed, no polyethylene sheeting is
required to be placed on the floor of the facility. The containment must be structurally sound so
that it will not collapse under negative pressure and work conditions. A structurally unsound
containment design will not be accepted. Polyethylene sheeting shall meet the requirements
in accordance with current TDH rules. Visible openings observed along the perimeter walls and
the ceiling shall be completely sealed polyethylene sheeting and the wall corners of the
containment should be attached with an overlap of at least twelve inches. The primary barrier
Asbestos Abatement Page 22
Asbestos Abatement - Hanger#5, City of Fort Worth, Texas
construction should form an air-tight, impermeable, permanent barrier around the ACM and
ACM debris to contain the release of asbestos fibers into the air.
1.10.6. EXTENSION OF WORK AREA:
If the enclosure barrier is breached in any manner that could allow the passage of asbestos
debris or airborne fibers, then where possible, add affected area to the work area. Enclose it as
required by this Section of the specification and decontaminate it as described elsewhere in this
section. If contaminated area cannot be added to work area, decontamination measures will
start immediately after contamination is discovered and work will stop in work area.
Decontamination procedures will continue until exposure returns to background levels.
1.10.7. SECONDARY BARRIERS:
Secondary barriers should be established in areas to separate any occupants or non-related
work activity from the abatement containment to prevent dust or debris from potentially
contaminating fresh air(make-up air) into the containment or regulated asbestos removal area.
1.11. MONITORING, INSPECTION AND TESTING:
1.11.1. GENERAL:
Perform throughout abatement work monitoring, inspection and testing inside the work area in
accordance with OSHA requirements and these specifications. I.H. Technician will continuously
inspect and monitor conditions inside the work area to ensure compliance with these
specifications. In addition, the I.H. will personally manage air sample collection, analysis and
evaluation for personnel and work area samples to satisfy OSHA requirements. Additional
inspection and testing requirements are specified in other parts of this section.
The Owner will employ a Certified Industrial Hygienist (C.I.H.) representative to perform various
services on behalf of the Owner. The C.I.H. representative or representative under the
direction of a CIH will perform the necessary monitoring, inspection, testing and other support
services to ensure that the Owner, employees and visitors will not be adversely impacted by the
abatement worked, and that the abatement work proceeds in accordance with these
specifications, that the abated areas or abated buildings have been successfully
decontaminated. The work of the C.I.H. representative in no way relieves the abatement
contractor from his responsibility to perform his work in accordance with contract documents, to
perform continuous inspection, monitoring and testing for the safety of his employees, and to
perform other such services as specified in this section. The cost of the CIH representative and
his services will be born by the Owner except for repeated final inspection and testing that may
be required due to unsatisfactory initial results. These repeated final inspections and testing, if
required, will be paid for by the contractor.
The asbestos contractor may request confirmation of above results. This request must be in
writing and submitted to the Owner's representative. Cost for the confirmation of results will be
born by the contractor for both the collection and analysis of samples and for the time delay that
may result for this confirmation. Confirmation sampling and analysis will be the responsibility of
the Contractor with review and approval by the C.I.H.

removed or protected.
4. Notify the Owner's representative on systems that need to be shut down as soon as
practical in advance. The Owner's representative will coordinate shutdown with
contractor and Owner's facility representative. The Owner's facility representative will
perform and monitor shutdown as required by contractor.
a. Shutdown and seal off all heating, cooling, ventilating or other air handling systems
serving the work area. The environment of the work area will be completely isolated
from all other air flows in the building. Owner's representative will monitor shutdown.
b. Shut down all electrical circuits which pose a potential hazard on the job. Exact
electrical arrangements will be tailored to the particular space and systems involved.
All electrical circuits will be turned off at the box outside the removal area, not just
the wall switch. Potential for electrical shock is a major threat to life in a work area
where large amounts of water will be sprayed on ceilings, conduits, lighting fixtures
and other electrical items. Electrical lines which are used to power work lights and
equipment will conform to all electrical safety standards and will be protected by a
ground fault interrupter. The asbestos contractor will be responsible for all OSHA
lockout/tagout requirements. A copy of the Asbestos Contractor's lockout/tagout
program must be submitted for review prior to asbestos abatement operations.
3.9.3. PREABATEMENT CONSTRUCTION AND OPERATIONS:
Perform all preparatory work for the first work area in accordance with the approved detailed
work schedule. Execute the preparatory work in accordance with this specification.
Upon completion of all preparatory work the Owner's representative will inspect the work and
systems to assure work is in accordance with these specifications. The Owner's representative
may require that upon satisfactory inspection the contractor's employees perform all major
aspects of the approved SOP especially on worker protection, respiratory protection,
contingency plans, decontamination procedures and monitoring to demonstrate satisfactory
operation. The operating systems for respiratory protection and negative pressure air systems
will be demonstrated for performance.
Upon satisfactory inspection of the installation and systems and satisfactory demonstration of
operations the Owner's representative will notify the contractor to proceed with abatement work.
3.2. REMOVAL OF ACM AND ACE:
3.2.9. WETTING MATERIALS: _
The Asbestos Abatement Contractor will adequately wet and remove all ACM as follows:
A. Spray wetting agent on the asbestos containing materials.
Asbestos Abatement Page 30
Asbestos Abatement - Hanger#5, City of Fort Worth, Texas
B. After wetting and removal, seal all ACM waste in leak-tight two layers of 6 millimeter
polyethylene while wet. For waste material not fitting into containers without additional
breaking, put material into leak-tight wrapping.
C. Label containers and wrapped material using warning labels as specified by OSHA 29
CFR 1910.1001 or 1926.1101 and the NESHAPS regulations.
D. For ACM being transported off the facility site, label ACM waste containers and wrapped
material with the name of the waste generator and the location where the waste was
generated.
3.2.2 SITE PREPARATION:
Erect Critical barriers at all doors and windows entering the regulated areas. This project will
be conducted by establishing critical barriers over all openings into the work area. A three
stage wet decontamination unit will be erected for worker entrance and exit into the work area.
The Contractor must establish negative air in the containment and maintain a pressure
differential of -0.02 inches of water column pressure differential. The following requirements
must be followed in areas where a -0.02 column inches of water pressure differential cannot be
established:
A. A negative pressure enclosure NPE must be used where the configuration of the work
area does not make erection of full containment enclosure feasible.
B. The negative pressure enclosure may be of any configuration.
C. At least 4 air changes per hour is to be maintained in the NPE.
D. The NPE must be kept under negative pressure throughout the period of its use, and
E. Air movement must be directed away from employees performing asbestos work within
the enclosure, and toward a HEPA filtration system.
F. A competent person must supervise all work and be licensed in Texas, as an asbestos
supervisor.
3.2.3. REMOVAL OFASBESTOS TRANS/TE:
This procedure is specified for the removal of asbestos cement transite.
Rope off work area and place warning signs. The Contractor will establish a 6 mil thick
polyethylene ground cloth barrier at a minimum distance of ten feet around the perimeter of the
work area prior to ACM removal activity. Any asbestos containing transite debris in the work
area should be adequately wetted and removed prior to establishing the perimeter ground cloth
barriers. The barrier should be bermed to prevent the release of ACM debris and/or
contaminated waste water from the work area.
Bring the necessary hand tools (i.e. pry bars, slatter's ripper, nail clippers) and materials into
the work area. Have a HEPA vacuum system available at all times. The HEPA vacuum will be
used to assist in the removal of ACM debris and ACE generated during the work.
Prior to transite removal, apply a amended water onto the ACM surface and allow to dry. The
amended water should be applied liberally in order to suppress any fiber emissions on
weathered shingles.
Asbestos Abatement Page 31
Asbestos Abatement - Hanger#5, City of Fort Worth, Texas
Make sure contaminants in the area have been cleaned with the proper methods before
beginning the work to avoid confusion concerning the source of the material.
Begin removal of cement asbestos shingles at the roof apex parapet wall. The cement
asbestos transite will be kept wet and removed as whole components to the best extent
possible in order to reduce potential airborne fiber emissions. If possible, remove in uniform
w
sections as installed.
Remove any nails or screws manually with hand tools, keeping the ACM wet (especially newly
exposed surfaces) through the entire operation.
The transite will be removed with minimal breakage utilizing hand tools and workers equipped
with a safety harness.
As pieced of transite are removed, lower them carefully'to the bottom of a disposal bag. Using
the broad putty knife or razor scrapers, scrape any remaining residue from the roof surface.
Rinse the roof surface with amended water while scraping.
Wet and remove any remaining ACM debris in the removal area using a scraper and place in
disposal bags. Hand-scraping may be done at the Contractor's option, or as required to
completely remove all material.
Lower disposal bags and/or securely wrapped ACM and roof components to the ground using
a rope or power lift. Do not drop disposal bags or poly-wrapped ACM to the ground.
As in any asbestos related project, the work area should be kept free of debris. Any
contamination should be .cleaned up immediately. When the work day is complete, (or as soon
as the project is complete) the work area should be cleaned using wet methods and/or a HEPA
vacuum.
All ACM at the end of the work day (or as soon as the procedures are completed) should be
placed in double layer 6 mil asbestos disposal bags. Dispose of waste in accordance with '
regulations for asbestos waste found in these specifications.
Workers should pass through a decontamination area when exiting the work area.
If the bag develops a leak, stop work inside the bag. Catch the water in a plastic disposal bag.
Lift and move the bag so that water stops running out. Do not "pump" the bag in a way that -
would force air out. Twist the bag in the area of the puncture to form a stem, dry the surface
and tape it securely closed. Clean up the contaminated water and debris from the area
immediately using wet methods and/or the HEPA vacuum. Dispose of the waste properly.
3.2.4. VINYL ASBESTOS TILE REMOVAL.
Those areas normally exposed to heavy foot traffic patterns usually have tiles adhered the
tightest. As a matter of good practice in starting the the removal, those sections which receive
the least traffic should be the locations selected for starting the removal of the tile. Since tiles
are normally in a 9" x 9" or 12" x 12" dimension, it should be the goal to remove individual tiles
as a complete unit to the best extent possible.
Asbestos Abatement Page 32
Asbestos Abatement - Hanger#5, City of Fort Worth, Texas
Start the removal by carefully wedging the wall scraper in the seam of two adjoining tiles and
gradually forcing the edge of one of the tiles up and away from the floor. Do not break off
pieces of the tile but continue to force the balance of the the up by working the scraper beneath
the the and exerting both a forward pressure and a twisting action on the blade to promote
release of the the from the adhesive and the floor.
When the first the is removed place it, without breaking it into smaller pieces, in the heavy-duty
impermeable waste bag or closed impermeable container which will be used for disposal.
With the removal of the first tile accessibility of the other tiles is improved. Force the wall
scraper under the exposed edge of another the and continue to exert a prying twisting force to
the scraper as it is moved under the tile until the tile released from the floor. Again, dispose of
the tile, and succeeding tiles, by placing in the heavy-duty bag or closed container without
additional breaking.
Some tiles will release quite easily while others require varying degrees of force. Where the
adhesive is spread heavily or is quite hard, it may prove easier to force the scraper through the
tightly adhered areas by striking the scraper handle with a hammer using blows of moderate
force while maintaining the scraper at a 2511 to 300 angle to the floor. Caution: Use safety
goggles.
If some areas are encountered where even the technique detailed in the previous paragraph
proves to be inadequate, the removal procedure can be simplified by thoroughly heating the
tile(s) with a hot air blower until the heat penetrates through the tile and softens the adhesive.
Note 1: Handle the hot air blower, tiles, and adhesive carefully to avoid personal burns.
Note 2: Do not handle the heated tiles and adhesive without suitable glove protection for the
hands.
As small areas of subfloor are cleared of tile, the adhesive remaining on the floor must be
scraped up with the 4" hand scraper until only a thin, smooth film remains. In those area where
deposits are heavy or difficult to scrape, the removal can be expedited by heating with the hot
air blower prior to scraping. Deposit scrapings in a heavy-duty impermeable trash bag or
closed impermeable container.
As indicated in previous paragraphs, tiles should be placed immediately in a waste disposal
bags or closed impermeable container. Do not attempt to break tiles after they are in the bag.
When all tiles have been removed from the floor and placed in polyethylene waste bags at least
6 mils thick or closed containers, seal the bags securely for disposal.
"Shot blaster" or"bead blaster' machines will not be allowed to remove the floor tile and mastic.
Alternate removal techniques may be used if approved by the CIH.

and mopping, and a HEPA filtered vacuum. Do not perform dry dusting or dry sweeping. Use
each surface of a cleaning cloth one time only and then dispose of as contaminated waste.
Continue this cleaning until there is no visible debris from removed materials or residue on •
plastic sheeting or other surfaces. Remove all filters in air handling system (s) and dispose of
as asbestos containing waste in accordance with requirements of these specifications.
3.7.6. SECOND CLEANING:
If the Asbestos Project Manager is not satisfied with the first cleaning, the Contractor will
perform a second cleaning inside containment. If the containment fails to pass final air
clearance criteria, the Contractor will perform additional cleaning inside containment.
3.7.7. PRE-CLEARANCE INSPECTION AND TESTING:

If airborne fiber counts exceed allowed limits, additional samples will be taken as necessary to
monitor fiber levels.
'At a minimum four (4) samples will be collected per containment area over the duration of work
in that area each day.
3.8.5. TEM SAMPLING:
The Owner's reserves the right to use TEM for confirmation purposes of final testing for a work
area. Up to 13 samples may be taken and analyzed. Up to five active samples inside the work
area and up to five active samples outside the work area using a MCEF filter media with a
minimum volume of 1,250 liters and a collection rate of 2 to 10.0 liters per minute. Two blanks
for every 10 samples collected will be taken from the job site.
3.8.6. LABORATORY TESTING FOR PCM:
The services of a AIHA P.A.T. accredited testing laboratory will be employed by the Owner to
perform laboratory analysis of the air samples. A technician will be at the job site, and samples
will be analyzed on-site. A complete record, certified by the testing laboratory, of all air
monitoring tests and results will be furnished to the Owner and the Abatement Contractor. The '
analytical laboratory must be licensed in accordance with State of Texas Civil Statutes Article
4477-3a pg. 295.54 in addition to being AIHA P.A.T. Accredited.
3.8.7. LABORATORY TESTING FOR TEM:
If the Owner's representative requests that final air clearance samples be collected and
analyzed by TEM, the samples will be sent to a qualified testing laboratory by overnight courier
for analysis. Verbal results will be available twenty four hours (24) after receipt of sample by the
laboratory. A complete record, certified by the testing laboratory, of all TEM results will be
furnished to the Owner and the Abatement Contractor.

3.8.8. FINAL AIR TESTING REQUIREMENTS:
Final air testing will be performed by phase contrast microscopy unless the Owner request final
air clearance by transmission electron microscopy. Clearance of the work space will be
performed by PCM. Final air testing requirements are outlined below: Clearance testing will
be required on all work activities inside the building. During transite removal, upwind and
downwind samples will be collected during the removal.
In each homogeneous Work Area after completion of all cleaning work, a minimum of three
samples will be taken inside the enclosure and analyzed as follows:
Samples will be collected on 25 mm, cassettes with the following filter media:
PCM: 0.8 mixed cellulose ester in a cassette with a conductive extension cowl.

Analysis: fibers on each filter will be measured using the NIOSH Method 7400 entitled "Fibers"
published in the NIOSH Manual of Analytical Methods, August 1994.
Fibers: Referred to in this section include fibers regardless of composition as counted by the
phase contrast microscopy method used.
Release Criteria: Decontamination of the work site is complete when every Work Area sample
is at or below the Detection Limit above. If any sample is above the Detection Limit then the
decontamination is incomplete and recleaning is required. When the results of the PCM air
samples are less than 0.01 f/cc, the area is deemed safe to occupy.
Calibrate sampling pumps and their flow indicators over the range of their intended use with a
recognized standard. Assemble the sampling system with a representative filter (not the filter
which will be used in sampling) before and after the sampling operation.
Record all calibration information. Ensure that the mechanical vibrations from the pump will be
minimized to prevent transferal of vibration to the cassette.
Ensure that a continuous smooth flow of negative pressure is delivered by the pump by
damping out any pump action fluctuations if necessary.
Select an appropriate flow rate equal to or greater than I liter per minute (Umin) or less than 10
L/min for 25 mm cassettes. Larger filters may be operated at proportionally higher flow rates.
If release criteria are met the Contractor will perform the abatement closeout and issue the
certificate of compliance in accordance with these specifications.
