    Construction & Demolition (C&D)
 Construction waste is defined as non-hazardous solid
waste resulting from construction, demolition and land-
 clearing activities, not including excavation material.
          What is current practice?

• All construction, demolition, and land clearing debris is
  hauled off site by private companies.
• Lowest bidder gets the job.
• All the prime contractors are responsible for their own
• Recycling and salvage are not mandatory. Certain
  materials of value (metal, wood, etc.) are recycled as a
  matter of course, averaging about 40-50% of total waste.
• There is little or no record-keeping.
                   Why Bother?
• Nationwide, C&D debris accounts for 25% to 45% of
  the total solid waste stream (by weight), with the
  balance consisting of regular municipal and
  commercial trash.
• In NYC, C&D accounts for more than 60% of the
  solid waste stream, according to a recent study by
  the NYC Department of Sanitation (DSNY), and 39
  % when clean fill materials are excluded.
• The City no longer has any operating waste disposal
  facilities (landfills or incinerators) within its borders.
                 Why Bother?
• As a result, all waste produced in NYC that is not
  recycled or composted, must be exported to disposal
  facilities located outside of the City.
• NYC currently produces about 33,000 tons per day of
  construction and demolition debris.
• Since the closure of Fresh Kills landfill, the
  Department of Sanitation's cost for waste disposal
  have increased from $42 per ton at Fresh Kills
  between $85-$90 per ton for export.
• You have an opportunity to help mitigate a serious
  problem and resource drain for New York City.
          High Costs

That is 33,000 tons a day x $90 =

  – $2,970,000 A DAY
  – $20,790,000 A WEEK
  – $89,100,000 A MONTH
  – $1,069,200,000 A YEAR (1Billion+)
  Why is Construction Waste
Management (CWM) important?

•   Reduces waste.
•   Reduces demand for virgin resources.
•   Reduces groundwater contamination.
•   Reduces emissions.
•   Reduces costs.
•   Creates jobs.
•   Provides low cost building materials.
•   Preserves green space.
    What are other Cities doing?
• San Francisco, CA and Portland, OR are recycling
  close to 50% of their waste, and have set targets as
  high as 75%.
• City of Seattle/King County, WA has a Construction
  Waste Management Program which focuses on
  education and technical assistance for the building
• The City of Chicago instituted a mandatory 50%
  recycling rate for C&D waste as of January 1, 2007.
     What are other States doing?

• The California Integrated Waste Management Board
  has set a statewide target of diverting 50% of C&D
  waste from landfills.
• The New Jersey Department of Environmental
  Protection has established a goal to recycle 50% of
  the municipal solid waste stream and has proposed
  statewide recycling legislation.
         What is the DDC doing?

 Issues Specific to City Contracting

• Contractual issues: Four prime contractors
• It’s different and new – requires education and
  attention to detail.
• To lead by example to address a major city problem
• It’s easy and relatively inexpensive to achieve these

       Demolition & Deconstruction

•   Must remove hazardous
•   Why not remove valuable
•   Deconstruction is the
    process that allows for
•   Requires dismantling,
    storage, protection and   Courtesy: Build It Green

    removal from site

•   First step of demolition
•   Must schedule time for it
•   More care must be used to
    dismantle for reuse rather
    than demolish (destroy for
    quick removal).
•   Must arrange for sale or
    donation of salvaged

           Construction Waste
•    Decide about on-site or off-site separation
    – Off site can achieve extremely high recycling
      • Not many sub-contractors/haulers do it.
•    On-site is much more complicated.
      • On-site separation and labeling of containers
      • “Policing” to avoid contamination
      • Scheduling of pickups
      • Housekeeping
  Post Collection Recycling (Offsite)

• No onsite separation
• Hauled to yard, dumped
  and separated
• Wood
• Metal
• Concrete
• Cardboard
• All residual waste
  transported to landfill.

            On-site separation?

• Do you have enough room?
• What materials will generate income?
• Will your hauler/subcontractor offer a reduced fee if
  recyclables are separated?
• Are there specific requirements for separating?
• How much contamination is allowed (e.g. painted
  wood, lunch waste?)

                       in a huge deconstruction effort,
                       donating 36 tons of reusable
                       building materials and
                       recyclables to the Community
                       Environmental Center (CEC).

                               This groundbreaking effort
                               directly contributed to the
                               creation of “Build it Green!”

   LEED-NC 2.2 Construction Waste
         Sample Narrative
• The project was completed over three phases from the
  summer of 2004 through the summer of 2006. During
  both construction and demolition, no waste was hauled
  directly to a landfill. The majority of waste was sent to
  mixed debris processing plants to reclaim recyclable
  materials. Reclamation rates ranged from 60 to 85%
  depending on the level of the mechanization at the
  processing plant and the composition of the debris.
  During demolition, there was also some source
  separation of concrete and brick, 100% of which was
  recycled. This represents an 80.43% waste diversion
  rate for the project.

            Back up
• For demolition, the contractor maintained and provided
  a spread sheet that tracked every container, service
  date, pick-up number slip, type of material, facility it was
  delivered to, type of facility, total weight, tons recycled,
  tons to landfill, tons incinerated and the facility recycling
• For construction, the contractor maintained and
  provided a spread sheet that tracked each container or
  ticket number, haul date, total tonnage, concrete, metal,
  wood, cardboard-paper and other materials diverted in
  tons, total diverted and total residual trash in tons,
  percent recycled and name and location of where the
  material went.
    Best Practices/Recommendations
•   Don’t drive yourself crazy but try to do something
    extra on each job.
•   Make GC responsible to manage the program, and
    provide on-call support for questions.
•   Educate and involve design team, contractors and
    subcontractors. Encourage their innovation
•   Stress waste avoidance to design team, contractors
    and subs.
•   Review reporting forms and plans with contractors
    and subs in advance.
•   Bring it up regularly in multiple meetings.
•   Review and return forms until they’re in compliance.
               Design Phase
• Make the design team aware of the C&D
  requirements and resources in the Design Guide.
• Suggest a building audit to identify salvageable
  and/or recyclable materials
• Schedule discussion of C&D management strategies
  and targets
• Insure integration of CWM spec and targets into the
  project specifications

• Discuss at pre-bid conference
• Request and review with the design team the GC
  waste management plan which should incorporate
  plans from other primes.
• Make sure that the GC designates a person to be
  responsible for C&D
• Require and review progress reporting including
  cumulative to-date totals.
             Lessons Learned

• It can be done easily and cheaply without delaying
  the schedule!
• It’s mostly about record-keeping and documenting
  what has been done.
• Insist on comprehensive and cumulative month-to-
  month tracking. You don’t want to try to figure out
  what has happened at the end of the job.
• Make the sub-contractors do the work for you.
