130 Liberty Street Deconstruction
• This presentation provides an overview of the 130
Liberty Deconstruction Project. Please record
questions that may arise as you view the
presentation and then join us in the main room to
discuss your questions directly with project
personnel.
• The presentation includes:
• Introduction
• Overview of the Deconstruction Phases
• Description of the Deconstruction Plan
• Project Timeline
130 Liberty Street Deconstruction
• The deconstruction of 130 Liberty Street will be
conducted in an overlapping 3-Phase process.
• The LMDC has prepared a Deconstruction Plan
that outlines the protocols that will be used to safely
clean and deconstruct 130 Liberty Street through
all phases of the project.
Deconstruction Plan Process
• The Deconstruction Plan has been revised based
on comments received by the Regulatory Agencies
in January, 2005.
• The LMDC submitted the revised Deconstruction
Plan to the Regulatory Agencies for final review on
June 14, 2005. The revised Plan can be viewed on
www.renewnyc.com/130Liberty and copies are
available for reference in the main room.
• No work on the deconstruction project will begin
until LMDC receives approval from the Regulatory
Agencies.
Deconstruction Phases
• Preparation Phase Includes:
– The erection of scaffolding on all four sides of the building;
– The erection of a personnel hoist on the exterior of the building; and
– The removal of the existing netting
• Phase I Includes:
– The cleaning and removal of all interior materials and non-structural
elements; and
– Will occur under negative pressure containment
• Phase II Includes:
– The deconstruction of the building structure including the removal of
the exterior wall systems, structural steel, and metal decking; and
– These deconstruction activities will occur from the top of the building
down
Deconstruction Plan
Section 1 - Waste Sampling and Management Plan
– Developed to properly classify, manage, containerize,
transport and dispose of (or recycle) waste streams that
will be generated as part of the Deconstruction.
– Anticipated waste streams include: dust; deconstruction
waste such as carpeting, doors and frames, raised
flooring, suspended ceiling tiles, etc; and other buildingrelated regulated material such as fire extinguishers, light
ballasts, lamps and batteries.
Deconstruction Plan
Section 1 - Waste Sampling and Management Plan
– Defines that all waste materials in Phase I will be
disposed of as asbestos waste at a minimum or cleaned
prior to disposal.
– Defines that all dust will be sampled and further
characterized for waste classification relative to other
identified contaminants, including COPCs to determine if
it must be handled as a hazardous waste in addition to
being handled as asbestos waste.
Deconstruction Plan Cont.
Section 1 - Waste Sampling and Management Plan
– Also includes:
• Transportation and Travel Routes will be determined in
coordination with New York City Dept. of Transportation
• Waste will be removed by New York State Dept. of Environmental
Conservation approved transporters.
• Waste transportation routes are currently under review and will
be appended to current plan.
• Disposal Facilities will be selected based on waste
characterization, facility acceptance criteria, etc.
• A list of potential disposal facilities is located in Attachment 3 of
the Waste Sampling Plan

Section 2 – Ambient Air Monitoring Program
– The Air Monitoring Program consists of 3 levels
of monitoring:
• Level 1: Air monitoring of on-site personnel.
• Level 2: Air monitoring both inside and outside the
active work areas.
• Level 3: Exterior ambient air monitoring within site
boundaries and at specific elevated locations adjacent
to the site.
Deconstruction Plan Cont.
Section 2 – Ambient Air Monitoring Program
– The Plan outlines:
• The extensive analytical list
• The proposed monitoring locations:
– Four (4) Street Level Stations at the four corners of the building
– Three (3) Elevated Stations at rooftop locations on adjacent buildings
– Two (2) Meteorological Monitoring Stations Ground and Rooftop
• Trigger Levels:
– Target Air Quality Levels
– US EPA site specific trigger levels
Deconstruction Plan Cont.
Section 3- Emergency Action Plan (EAP)
– The EAP identifies:
• That all on-site personnel upon discovering an
emergency situation shall immediately call 911.
• That the Contractor Emergency Coordinator will
function as the on-site representative to the First
Responders.
• Response actions for specific emergency events
including fire/explosion, power failure, structural
failure, unplanned release of hazardous/regulated
waste, medical emergency and rescue, and falling
or dropped building components.
Deconstruction Plan Cont.
Section 3- Emergency Action Plan (EAP)
– The Community Notification Plan, which is appended
to the EAP as Appendix F, outlines the community
notification protocol, per type of incident, that LMDC
will implement in the event of an emergency:
– Incident Types Include:
•
•
•
•
On-site incident not affecting the community
City emergency, i.e. power failure, water main break, etc.
Neighborhood Impact Emergency
Air Monitoring Exceedance
Deconstruction Plan Cont.
Section 4- Abatement and Removal of Asbestos and
Contaminants of Potential Concern (COPCs).
– Developed to prevent potential exposure of workers
and the public to asbestos fibers and other
contaminants in the building;
– Safeguards workers and the public from construction
debris and materials; and
– Maintains a safe working and neighborhood
environment.
Deconstruction Plan Cont.
Section 4- Abatement and Removal of Asbestos and
Contaminants of Potential Concern (COPCs).
– Defines that the sequencing of Phase 1 work will be as follows:
• work area preparation including the installation of High Efficiency
Particulate Air (HEPA) ventilation equipment, pre-cleaning, and
installation of isolation barriers;
• establishment of waste and personal decontamination systems areas;
• establishment of the negative pressure work area;
• removal of ACBM materials, WTC dust and debris and all interior
building equipment, components and materials by certified personnel;
• packaging, transport, and disposal of waste materials;
• on-going air monitoring;
• detail cleaning of work areas;
• and clearance air testing

Section 5- Health and Safety Plan (HASP)
– The HASP was developed to prevent occupational
injuries and exposures to chemical, physical and
biological hazards to workers at the site and defines:
•
•
•
•
•
•
•
•
Roles and Responsibilities
Project-Specific Task Hazard Analysis and Risk Assessment
Identifies the Physical, Chemical, Biological Hazards
Engineering Controls
Administrative Controls
Personal Protective Controls
Personal Air Monitoring Requirements
Site Control and Work Zones
Deconstruction Plan Cont.
Section 5-Health and Safety Plan (HASP)
– The HASP includes, without being limited to, the
following procedures:
• Personnel: Participate in site orientation/training, follow
designated safety and health procedures, and utilize specified
personal protective equipment, such as respirators.
• Contractors: A licensed New York City Site Safety Manager
(NYCSSM) will be on-site throughout the project and will have
the daily responsibility of ensuring implementation of the HASP.
• Subcontractors: Each subcontractor must prepare a HASP for
its project tasks; have a supervisor on-site who understands all
potential health and safety issues associated with specific tasks;
provide a subcontractor safety officer to ensure compliance with
the provisions of both the LMDC HASP and the subcontractor
HASP; ensure appropriate training; and provide daily health and
safety briefings to personnel.
Next Steps
• As LMDC awaits final approval of the
Deconstruction Plan from the Regulatory
Agencies, details of the Preparation Phase are
being finalized.
• The Preparation Phase will include:
– Erection of a scaffolding system on all four sides of the
building, that will be fully enclosed with protective
netting.
– Incorporation of sidewalk bridging to the scaffolding
system and installation of additional sidewalk bridging
along Albany Street.
– Installation of a personnel hoist.
– Removal of the existing netting.
Next Steps
• Once the Preparation Phase is underway Phase I
Cleaning and Abatement work will commence at
the top of the building and work downward.
• Once several floors have been cleaned, leaving a
minimum of a 5 floor buffer zone, Phase II
structural removal work will begin.
• LMDC will continue to keep the public informed of
the start and progress of each Phase in the
deconstruction.
