Initial Building Characterization Study
Louis Berger Group, Inc.
130 Liberty Street Building Deconstruction
World Trade Center Redevelopment
New York, New York
September 23, 2004
Initial Building Characterization Study, cont.
The objectives of the study were to:
• Characterize the contamination levels in the building;
• Provide recommendations for further sampling; and
• Serve as a reference for the development of the cleaning and
deconstruction plan.
It is important to note that this was only an initial
characterization study. LMDC will conduct additional
testing and sampling.
Initial Building Characterization Study
• In May 2004, LMDC contracted with Louis Berger Group, Inc.
to perform an initial characterization study of the 130 Liberty
Street building.
• The goal of the study was to identify any contaminants
present in the building that should be addressed during the
cleaning and deconstruction process.
• The building will be cleaned and methodically deconstructed.
As a safety precaution, the deconstruction will not use
explosive devices.
Initial Building Characterization Study, cont.
The study will help LMDC:
• Address concerns about community and worker health and
• Develop engineering controls and precautionary work
practices to ensure public health and safety and protect the
• Use cleaning and disposal procedures that properly address
all identified contaminants; and
• Comply with all applicable federal, state and local regulations
throughout the cleaning and deconstruction process.
Initial Building Characterization Study, cont.
What did the initial study include?
• Sampling and analysis of suspect asbestos-containing
building materials (ACM);
• Sampling and analysis of dust for asbestos and key WTC
Contaminants of Potential Concern (“COPCs”) as defined by
EPA, as well as other suspected contaminants;
• Visual observations for the presence of mold on exposed
surfaces; and
• Screening of the indoor air for mercury vapors.
• Asbestos Containing Materials
(ACM): Approximately 2,000 bulk
material samples were taken.
• Asbestos in Dust and Other
Contaminants of Potential
Concern (COPC): Approximately
1,600 bulk-dust samples were
Asbestos and dust
samples were
characterized using
either Polarized Light
Microscopy (PLM) or
Electron Microscopy
• Mold: Visual inspection of accessible spaces.
• Mercury Vapor: 153 samples taken.
The building was divided into
six sampling zones that were
established based on visible
levels of dust and the potential
point of entry.
Task 1: Study Planning
• Sampling and Analysis Plan (SAP)
• Quality Assurance Project Plan (QAPP)
• Site Specific Health and Safety Plan (HASP)
Task 2: Asbestos Containing Material (ACM)
• The majority of samples tested
negative for asbestos, including
spray-on fire-proofing, wall-board,
roofing materials, and most
thermal insulation for piping and
• Approximately 155,000 square feet
of flooring and wall materials, and
95,000 linear feet of caulk,
insulation and sealant materials
were identified throughout the
building as ACM.
Most of the ACM are
considered “NonFriable” by state
definition. This
means that they
cannot be crumbled
by hand pressure.
Tasks 3 & 4: Asbestos in Dust and Other
Contaminants of Potential Concern (COPC)
• Contaminants of Potential Concern (COPC) identified by the
EPA as associated with WTC dust
– Asbestos, dioxins, lead, polycyclic aromatic hydrocarbons (PAHs),
and crystalline silica
• Other Contaminants
– PCBs
– Heavy metals: barium, beryllium, cadmium, chromium, copper, lead,
manganese, mercury, nickel, and zinc
Tasks 3 & 4: Asbestos in Dust and Other
Contaminants of Potential Concern (COPC)
• Approximately 1,600 bulk dust samples were taken
throughout the building.
• The samples showed varying levels of asbestos, COPCs
associated with WTC dust, and other contaminants.
• The contaminants were identified in dust located above and
below the suspended ceiling (plenum).
• Further testing will be conducted on surfaces and in spaces
that were previously inaccessible.
Tasks 3 & 4: Asbestos in Dust and Other
Contaminants of Potential Concern.
Although they do not directly apply, the sampling results were
compared to EPA’s WTC residential background and 30-year
re-occupancy cleanup benchmarks to provide a better
understanding of the results. Analytes that exceeded the
criteria include:
• Asbestos (exceeded in 77% of floors tested)
• Dioxin (exceeded in 99% of samples)
• Lead (exceeded in 97% of samples)
• Quartz (exceeded in 94% of samples)
• PAHs (exceeded in 80% of samples)
• Chromium (exceeded in 30% of samples)
• Manganese (exceeded in 21% of samples)
Task 4: Other Analytes in Dust, cont.
• Cristobalite, Barium, Cadmium, Copper, Zinc, and Mercury
exceeded the criteria in less than 5% of the samples
• Nickel, Beryllium, and PCBs did not exceed available
residential criteria in any of the samples tested.
– PCB levels were compared to the EPA spill cleanup criteria
because no residential background or residential benchmark
levels related to WTC are available from EPA.
Task 4: Mercury Vapors
• A preliminary screening for mercury vapor was performed
after LMDC acquired the building.
• The screening was performed to evaluate potential worker
health and safety issues associated with mercury vapor
because of its unique ability to vaporize at room temperature.
• Based on the measurements obtained from a direct-read
screening device, there were no detectable mercury vapor
levels in the open spaces within the building.
Task 5: Mold
• The visual mold inspection revealed building materials with
mold on exposed surfaces in seven locations distributed over
five different floors (11th, 7th, 3rd, Basement A, and
Basement B).
• In total, 105 SF of mold-impacted building materials were
• Inspection was not performed for non-exposed surfaces and
will be performed as part of the supplemental testing for the
cleaning and deconstruction program.
• The results of the sampling and testing revealed levels of
contaminants that should be addressed in the deconstruction
of the building.
• Throughout the building, asbestos containing materials
(ACM) were positively identified.
• Detectable levels of asbestos, silica, PAHs, dioxins, PCBs,
and heavy metals (including mercury) were also identified in
dust above and below the suspended ceilings.
• The results are consistent with the highly variable nature of
WTC dust and the level of activity that has occurred within
the building since September 11th.
Further Testing
Further testing will occur in previously inaccessible
surfaces and interstitial spaces including:
• The curtain wall, interior walls, the exterior of the building,
and cell systems and raceways within the concrete slabs;
• Testing for all of the constituents addressed in the initial
characterization study (asbestos and other analytes as well
as visual inspection for mold).
Additional testing will also be performed to characterize
waste materials prior to handling, transportation,
storage, and disposal or recycling.
Major Recommendations
• Maintain, review, and modify the current health and safety
plan and external air monitoring program as appropriate to
address the conditions identified in the study;
• Continue to review and address the potential for release of
contaminants from the building and further develop and
implement an emergency action plan;
• Conduct further testing as recommended, further develop the
cleaning and deconstruction plan, and continue to consult
with all appropriate regulatory agencies;
Major Recommendations, cont.
• Further develop appropriate site-specific health and safety
plan and work and site operations documents;
• File appropriate notifications and obtain necessary permits,
including the Asbestos Control Program 7 (ACP-7), from the
appropriate regulatory agencies and engage a contractor
with a NYSDOL asbestos handling license to perform the
work; and
• LMDC should conduct appropriate monitoring and quality
assurance/quality control inspections throughout the cleaning
and deconstruction process.
