to the containment and shall seal any visible penetrations leading to the containment
area.
R. Contractor shall be required to construct a full and attached decontamination unit
per CDPHE requirements and as specified in section 01563.
S. Owner will not attempt to enforce such laws and regulations; however, Owner has
the authority to stop asbestos abatement work when conditions are not in compliance
with the specifications or applicable federal, state, or local regulations. Safety of
the project area for the protection of the Contractor, Owner and the general public is
the responsibility of the Contractor. Owner is solely responsible for evaluating
compliance with applicable federal, state, and local regulations.
1.7 INSPECTIONS AND AIR MONITORING BY OWNER:
A. Coordinate Owner inspections: All work and material shall be subject to
visual inspection by the Owner. The Contractor shall provide reasonable and
necessary facilities for such observation and shall render the assistance
necessary to permit the Owner to carry out all phases of observation.
1. When required by Owner, the Contractor shall take down or uncover portions
of the finished work. If the work thus exposed is satisfactory to Owner, the
cost of exposing and restoring the same shall be at the expense of Owner, but,
if in opinion of Owner, work is unsatisfactory, all cost and expenses of
exposing, removing, retesting, replacing and restoring shall be borne by the
Contractor.
2. Any omission or failure on the part of Owner to disapprove or reject any
inferior or defective work or material shall not be construed to be an
acceptance of any such work or materials. The Contractor shall remove at its
own expense any defective work or material rejected by Owner and shall
rebuild or replace the same without extra charge to Owner. All retesting of an
area for clearance shall be at the Contractor's expense.
3. All inspections shall take place during normal working hours. If inspections
occur past normal working hours, the Contractor shall bear the costs incurred
by Owner as result of the additional labor of Owner.
4. Where the Owner has an on -site representative, the Contractor shall give the
Owner two (2) hours advance notice of an impending inspection. Where the
Owner does not have an on -site representative, then a 24- hour advance notice
of impending inspection is required.
5. If the inspection detects items to be corrected the area will be termed "failed"
and will need to have corrective action taken by the Contractor.
6. The Contractor must allow for a two (2) hour notice period before the re -
inspection of the failed area may begin (this may be waived by Owner). Items
of work requiring inspection sign -off by Owner are:
a. Pre -Abatement (Area Preparation/Containment) Inspection Removal of
asbestos and necessary demolition shall not take place until Owner has
inspected area preparation work and given approval.
b. Final Visual Inspection - The area shall not be encapsulated or locked down
until Owner has inspected and given approval of the final cleaning and area
decontamination. The containment must be completely dry, during the
inspection with no water droplets, remains or saturation on polyethylene
sheeting or other surfaces in the containment.
C. Contractor shall request in writing (via speed memo or fax) required Owner
inspections including the time and date of the requested inspection.
7. The inspections are listed in the applicable specification paragraphs. A punch
list of items to be corrected resulting from the "failed" inspection, will be
prepared jointly by the Contractor and Owner prior to final acceptance of the
project by the Owner. Inspections shall in no way be construed as final or
partial acceptance by Owner. Any failure or omission of the Owner to notify
the Contractor of defective work shall not excuse Contractor for liability for
such defective work.
8. It will be necessary that the Contractor successfully confine fiber release to the
designated work area and within the containment. Owner obligations are
solely to Owner. In meeting such obligations Owner may increase the burdens
and expense of the Contractor, his Sub -Contractors or employees, or the
surety of them. Nothing in the performance of Owner services in connection
with this project implies the undertaking for the benefit of, or which may be
enforced by, the Contractor, his Sub -Contractors, or employees, or the surety
of any of them. It is not the function of Owner to specify all of the means by
which the Contractor will attain the intended results, nor to state all of the
environmental conditions that must be present for the safety of workers who
are employed to produce the intended results, or for the safety of others during
construction. The Contractor shall establish means and environmental
conditions that meet applicable laws and regulations.
9. The Contractor is required to removal all specified ACM. Any ACM, debris
or contaminated materials, missed, not accessed or abated thoroughly, and
later discovered by the Owner, will be corrected by the Contractor at no cost
to the Owner.
B. Owner Authority to Stop Work and Reassign Employees
1. Owner shall have the authority to stop work. Such work stoppage may occur
at any time it is determined that conditions at the job site are not within the
scope of the specifications, or that a health hazard might exist for workers or
building occupants. The stoppage of work shall continue until conditions have
been corrected.
2. All downtime during the work stoppage will be at the expense of the
Contractor. Similarly, the standby time required to correct conditions leading
to the work stoppage shall be at the Contractor's expense.
3. Owner shall have the authority to require the asbestos Contractor to reassign
employees who violate any provisions of the decontamination and work
procedures in the specifications, or who are deemed by the Owner to work in
a manner which is not consistent with industry standards, or health and safety
guidelines.
4. In the event that the Contractor's project supervisor or foreman refuses to
cooperate with Owner with regard to health and safety issues (including issues
concerning these technical specifications), Owner reserves the right to require
the Contractor to replace the uncooperative individual.
C. Owner will provide Project Manager for the project that will include strategic
inspections.
D. Air Monitoring by the Owner Air monitoring may be conducted both outside and
inside of the work area during the work, prior to the project, and for clearance
sampling at the end of the project
1. Outside of the Work Area: The Owner shall retain the right to sample air
outside of the work area to detect faults in the work area isolation such as:
a. Contamination of the building outside of the work area with airborne asbestos
fibers,
b. Failure of filtration or rupture in the differential pressure system,
C. Contamination of air outside the building envelop with airborne asbestos
fibers.
2. Inside the Work Area: The Owner shall retain the right to monitor airborne
fiber counts in the Work Area. The purpose of this air monitoring is to detect
airborne asbestos concentrations that may challenge the ability of the Work
Area isolation procedures to protect the balance of the building or outside of
the building from contamination by airborne fibers.
E. Work area clearance: Clearance air sampling shall be conducted by the
Owner at the completion of asbestos abatement work is described in Section
01712 Work Area Clearance.
F. Personnel air monitoring required by OSHA is the responsibility of the
Contractor and is not covered in this section

PART 2 - PRODUCTS (Not Applicable)
PART 3 -EXECUTION
3.1 WORK SEQUENCE:
SEQUENCE OF EVENTS
A. This section provides a general summary of the work sequence. Where steps
were
omitted, the general steps listed below shall apply as the general sequence
of events for all phases. Contractor is bound to the conditions within this set of
specifications, unless otherwise specified in this section. Owner shall be
responsible for the determination of overlapping or unnecessary steps.
1.
The Contractor shall establish and attach a personal decontamination unit to
the work area positioned for maximum efficiency in abatement and
convenience to the Owner. The decontamination unit will remain for the
duration of the project.
2.
The Contractor shall then establish and attach a separate (minimum two
chamber) waste load out to the work area.
3.
The Contractor shall establish a restricted area where work is to be performed.
Install visual or physical barriers where required. Install visual barriers to
minimize visibility of activities. Install physical barriers where work is
performed in an area that cannot be secured by other means (locked door,
gate, etc).
4.
Install critical barriers to fully isolate the area and establish a minimum
pressure differential of -0.030 inches of water column.
5.
Post danger signs restricting access to the area to authorized personnel only
(Danger - Asbestos signs).
6.
Pre -clean all horizontal surfaces and movable objects.
7.
Remove all movable objects from the work area, ensuring proper
decontamination of these items prior to removal from the restricted area
through the waste load out.
8.
Install other polyethylene barriers as required (floors, walls, ceilings, etc.).
9.
Prior to removal, the Contractor shall lay 6-mil drop cloths in the basement
below the Work Area.
10.
Upon completion of a pre -abatement visual inspection by a representative of
the Owner, removal of asbestos -containing material may begin, using
appropriate techniques such as wetting and vacuum practices. At a minimum,
the Contractor shall use full face Powered Air Purifying Respirators (PAPRs)
for removal and cleanup work within the Work Area. If APRs are used, the
Contractor must provide initial exposure assessment (IEA) to indicate that
higher levels of respiratory protection are not required. This exposure
documentation must be from similar projects and provide reliable expected
values. If documentation is not provided which justifies the lesser protective
APR, the Contractor must use higher levels of protection as required by
OSHA.
11.
Upon completion of removal of initial gross ACM and associated debris, the
Owner's Representative shall conduct a visual inspection of the Work Area
and collect measurements of soils depth.
12.
The Contractor shall then be permitted to begin contaminated soils removal via
truck -mounted vacuum system.
13.
Properly seal, label and transport and dispose of all ACWM in accordance
with applicable regulations.
14.
Owner is not responsible for the Contractor's OSHA compliance monitoring.
The Contractor shall post all air monitoring results on the site within 24 hours
after collection of the sample(s).
15.
The Contractor shall clean all surfaces after removal utilizing HEPA
vacuuming and wet wipe methods.
16. The Owner will provide final visual inspection for all work areas and work
Area Clearance for containments. Samples exceeding 0.01 f/cc will be
deemed to have failed, and must be either analyzed by TEM (at the
Contractor's expense) or the area re -cleaned and re -tested (to avoid scheduling
and cost implications associated with TEM analysis unless otherwise specified
by the Owner).
3.2 STOP ACTION LEVELS:
A. Inside Work Area: The following applies to both personal and area air
monitoring conducted within the Work Area. For Full Containments maintain
an average airborne count in the work area of less than the Stop Action Level
given below (to protect workers to 0.01 f/cc within the mask) for the type of
respiratory protection in use. If the fiber counts rise above this figure for any
sample taken, revise work procedures to lower fiber counts. If the Time
Weighted Average (TWA) fiber count for any work shift or 8 hour period
exceeds the Stop Action Level, stop all work except corrective action, leave
pressure differential and air circulation system in operation and notify the
Owner. After correcting cause of high fiber levels, do not recommence work
for 24 hours unless otherwise authorized, in writing, by Owner. If 0.1 f/cc is
exceeded, the Contractor shall install a secondary containment as described
above prior to recommencing component removal activities.

B. Outside Work Area: If any air sample taken outside of the Work Area exceeds
the CDPHE Maximum Allowable Asbestos Level (MAAL), immediately and
automatically stop all work except corrective action. The Owner will
determine the source of the high reading and so notify the Contractor in
writing.
1. Maximum Allowable Asbestos Level
a. Air monitoring shall be conducted during normal occupancy and samples
shall not be collected in an aggressive manner.
b. Where PCM is used as the method of analysis the standard is 0.01 fibers per
cubic centimeter of air (f/cc) which is equivalent to 10,000 fibers per cubic
meter of air (f/m3). The NIOSH 7400 Method shall be used to analyze
samples. The number of samples to be taken shall be determined by the air -
monitoring specialist. Where TEM is used as the method of analysis, the
standard is 70 structures/millimeter (s/mm�). TEM analysis shall be
conducted pursuant to the protocol in 40 C.F.R. Pats 763, Appendix A to
Subpart E (EPA 1995).
C. All air monitoring collected for MAAL and Clearance purposes shall be
performed by the Owner's representative who is independent of the
abatement contractor to avoid possible conflict of interest.
2. In the event that airborne fiber levels outside a Work Area exceeds the MAAL
when analyzed by PCM (when verified by TEM), the Contractor shall comply
with CDPHE requirements for Major Asbestos Spills (Regulation 8 III.C.5.b).
If the high reading was the result of a failure of Work Area isolation measures
initiate the following actions:
a. Immediately erect new critical barriers as set forth in Section 01526
Temporary Containments to isolate the affected area from the balance of the
building. Erect Critical Barriers at the next existing structural isolation of the
involved space (e.g. wall, ceiling, floor).
b. Decontaminate the affected area in accordance with the Sequence of Events
section of this section of the specifications.
12
C. Require that respiratory protection as set forth in this section and applicable
regulatory requirements he worn in affected area until area is cleared for re -
occupancy.
d. Leave Critical Barriers in place until completion of work and ensure that the
operation of the pressure differential system in the Work Area results in a
flow of air from the balance of the building into the affected area.
e. If the exit from the clean room of the personnel decontamination unit enters
the affected area, establish a decontamination facility consisting of a Shower
Room and Changing Room as set forth in Section 01563 Decontamination
Units at entry point to affected area.
I. After Certification of Visual Inspection in the Work Area remove critical
barriers separating the work area from the affected area. Final air samples
will be taken within the entire area as set forth in Section 01712 Work Area
Clearance.
3. In the event that areas beyond the work area become contaminated with
asbestos, asbestos -containing dust/debris, and/or visible emissions from the
work area, the Contractor shall be responsible for all costs associated with
cleaning and subsequent testing (visual inspection, air sampling and bulk
analysis) of these areas.
4. If the high reading was the result of other causes initiate corrective action as
required by the Owner.
C. Effect on Contract Sum: Complete corrective work with no change in the Contract
Sum if high airborne fiber counts were caused by Contractor's activities. The
Contract Sum and schedule will be adjusted for additional work caused by high
airborne fiber counts beyond the Contractor's control. Contractor is responsible for
all costs associated with TEM verification where PCM samples exceed 0.01 f/cc,
and any subsequent cleaning and additional sampling costs.
3.3 STOP WORK:
A. If the Owner presents a written stop work order, immediately and automatically
conform to that stop work order, while maintaining temporary containments and
pressure differential. Do not recommence abatement work until authorized in
writing by Owner.
B. Immediately initiate the following actions: After being presented with a stop work
order immediately:
1. Cease all asbestos removal activities, or any other activities that disturbs ACM.
2. Repair any fallen, ripped or otherwise failed work area isolation measures.
3. Maintain in operation all work area isolation measures including those required by
Sections 01526 Temporary Containments, 01513 Temporary Pressure Differential &
Air Circulation System, 01563 Decontamination Units.
4. Maintain all worker protections including those required by this section and all
applicable regulatory requirements.

PART 3 - EXECUTION
3.1 PROCEDURES
A. For crawlspaces/tunnels without significant debris/soil contamination, or
where wood construction / structures are present, install a full containment per
Section 01526. Where significant debris and/or soil contamination is present, in
concrete and/or metal construction, and where a variance has been obtained from
CDPHE to waive installation of secondary and primary barriers (protective layers
on floor, walls and ceiling), install 6-mil poly drop cloths that extend 10 feet beyond
all TSI that is to be removed from piping.
D. Establish personal decontamination unit, waste load -out, exterior critical
barriers and negative pressure ventilation units. Establish negative —0.02" prior to
entering space.
C. Wet and collect visible debris on top of the soil that would be disturbed
performing precleaning and critical barrier installation. Pre -clean and install
critical barriers over vents, access openings, floor penetrations, ducting and
other locations to isolate the crawlspace/tunnel. Using plastic wire ties, clean
and string cables, cords, wires and other existing items in a manner that these
items are will not be damaged during abatement activities. Install additional
barriers (primary, secondary and drop cloth) as required by regulations and
specification. A minimum —0.03" and 6 air exchanges per hour shall be
installed.
E. After passing a pre -abatement inspection by the Owner, removal of TSI may
commence with adequate wetting procedures. Place TSI directly into bags as
the material is removed, while bags are on drop cloth. After removal and
cleaning of piping, remove and dispose of all drop cloths.
F. Remove and properly dispose of all movable objects including rocks, stones,
wood and other debris and/objects. Follow the following protocol for disposal
or decontamination.
1. All porous materials, including but not limited to: fiberglass insulation (both on the
pipe and loose), loose drywall, and loose porous wood shall be disposed of as
asbestos -containing material. All loose non -porous materials including, but not
limited to: metal, glass, non -porous wood and plastic shall be decontaminated and
removed from the area. The Owner shall designate an area for storage of these non-
porous materials (e.g. room or dumpster). Where fiberglass insulation has a non-
porous outer surface, at the Owner's discretion, insulation may be left on piping,
with the outer covering shall be cleaned, and then coated with a bridging encapsulant.
2. The Contractor is responsible for removing fixtures, objects and other items that may
be required to facilitate abatement activities (i.e. installation of exhaust, access to
ACM, etc.). The movement and handling of all movable objects and surfaces within
specified area are within the scope of work.
3. The Contractor is responsible for removing and/or excavating under ducts, pipes or
other items and/or objects to improve access and allow passage throughout the work
area.
G. After removal of all movable debris and objects, remove of top 2" or soil (or
other depth as specified) using Asbestos Removal Vacuum System. If
required, as directed by Owner, additional 2" layer of soil will be paid at
Contract Unit Price per square foot of additional soil removal. Utilize an
airless spray for wetting at point of vacuum intake, with additional wetting and
bag discharge (water injection nozzles at fully enclosed discharge valve). Start
removal at the point of work closest to the make-up air, and proceed toward
the negative air machine. Do not permit traffic into the fresh soil surface,
except for main travel paths. Re -vacuum main travel paths working way out of
area, from Negative Air Machines to Entrance (make-up air).
3.2 SPECIAL CONSIDERATIONS
A. All lighting in crawlspace/tunnel areas are responsibility of the Contractor.
Provide string lights for uniform general area lighting to eliminate all dark or
shadow covered areas. Provide portable halogen lights for task specific lighting
(preparation, removal, cleaning, etc). Provide a sufficient quantity of replacement
light bulbs.
B. Stage Vacuum System where directed by Owner. All waste discharge
operations shall be conducted within a negative pressure secondary containment
with attached air lock for entry/egress. Provide for continual monitoring of
negative pressure within the waste bagging area. Waste discharge shall meet all
applicable regulations and accepted industry standards. Contractor is responsible
for all costs associated with the installation and configuration of the Vacuum
System (concrete coring to provide access for vacuum hoses, etc) and Negative
Pressure Ventilation (Containment) System, and Decontamination Units.
C. Arrange negative pressure air filtration units in a manner that allows for
proper airflow throughout the crawlspace. Use smaller portable machines, remote
intake devices and ducting to achieve uniform airflow and to eliminate dead
airspaces.
D. The Contractor is responsible for complying with regulatory requirements and
standard industry practice for other hazards that may be encountered within a
crawlspace and/or tunnel area. Contractor shall provide safety awareness training for
such hazards. These include but are not limited to:
1. Heat stress - provide heat stress monitoring in hot environments. Provide adequate
breaks for workers to replenish fluids and cool down. Provide appropriate protective
equipment for working around hot equipment.
2. Biological hazards (snakes, spiders, broken sewer pipes, rodent droppings, etc) -
Provide appropriate protective and preventative measures.
3. Confined spaces - Provide appropriate monitoring and protective measures
3.2 FINAL VISUAL INSPECTION AND SOIL SAMPLING
A. Baseline soil measurements will be compared to post abatement soil
measurements to verify that 2" of soil has been removed. The Contractor
17
shall remove any additional soil in areas directed by Owner where soil
measurements indicate that a 2" layer has not been removed.
B. Owner will provide a final visual inspection of the work area. All cleanable
surfaces including concrete walls, metal decking, piping and other items must
be visually clean of dust and debris. Owner will provide a final visual
inspection of soils to verify that all visible debris within the soil has been
removed. Contractor will remove additional 2" of soil as directed by Owner,
where visible debris is noted.
C. After removal of all asbestos -containing material, debris, and soil, Owner will
collect soil clearance samples for testing by Polarized Light Micrsocopy
(PLM). Owner will collect one bulk soil sample per 1,000 square feet of area,
or a minimum of 9 samples, which ever is greater. The random grid method
shall be used to determine the locations of bulk soil samples. Soil removal is
complete when all bulk soil samples indicate no (0%) asbestos detected.
Samples with the presence of asbestos (trace or greater) will be deemed to
have failed. In areas where samples fail clearance samples, an additional 2"
layer of soil will be removed at the direction of the Owner. At the discretion of
the Owner, once two consecutive bulk samples from the same grid area yield
results of trace asbestos, the grid shall be considered to have passed the soil
clearance criteria. Once all soil samples pass PLM clearance , the Contractor
shall apply lock -down encapsulant for aggressive clearance of the area
according to CDPHE recommendations. Per CDPHE recommendations, use
a leaf -blower during lock -down operations to assist with application of lock -
down. Apply lockdown during leaf -blower operations until no visible dust in
the air is observed.
3.3 LOCK DOWN (LOCKBACK)
A. Encapsulation materials shall be a penetrating or bridging type, pollution -free, non-
toxic, with a Class A fire classification as specified herein. Material shall be
flexible when cured, resistant to weathering, oxidation, aging, and abuse. The
Contractor shall submit product data, use instructions, and recommendations from
the manufacturer for products intended for use. The Contractor shall use only the
type of encapsulant or lockdown approved by Owner.
3.4 WORK AREA CLEARANCE:
A. After completion of all work and prior to removal of critical barriers,
decontamination units, and shut down of pressure differential and ventilation
system; complete project decontamination and clearance in accordance with section
01711 "Project Decontamination."
B. Owner will conduct final clearance air sampling using aggressive air sampling
techniques (leaf -blower and fans). Once the work area is visually clean,
where all bulk samples meet soil clearance criteria, and airborne levels have
been reduced below the clearance level 0.01 f/cc (PCM) or 70 st/mm2 (TEM)
the work meet Contractor Release Criteria. If the first round of final clearance
air monitoring fails PCM and subsequent TEM analysis, additional inspection
and testing will be at the expense of the contractor.
