LEED & Green Construction Waste Management Pamela Lippe LEED, AP email@example.com DESIGN + CONSTRUCTION EXCELLENCE Continuing Education for NYC Capital Program Staff Construction & Demolition (C&D) Waste 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 waste. • 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 industry • 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? Web-based Resources • C&D Waste Management Manual • Sample specification • Sample waste management plan • Waste management reporting forms will be available soon on the website. • Waste recycler list. Ask for a copy from Office of Sustainable Design. Issues Specific to City Contracting Obstacles • Contractual issues: Four prime contractors • It’s different and new – requires education and attention to detail. Opportunities • To lead by example to address a major city problem • It’s easy and relatively inexpensive to achieve these credits for LEED.

How is it done? • Planning • Specifications • Waste Management Plans and Forms • Bid Process • Contractor and Subcontractor Education Courtesy: Pamela Lippe Planning • Set goals. 75% is easy. • Conduct hazmat survey as required by DDC policy • Conduct pre-demolition survey. Outside expert? – Identify materials of value • Doors, beams, lighting, water-efficient fixtures, chillers, structural steel. Courtesy: Pamela Lippe Planning • Develop strategies to maximize value for the contractor or the community. Identify markets for material. Research take-back programs. • Are there any opportunities for reuse on the job? • Decide about on-site and/or off-site recycling Courtesy: Pamela Lippe Construction Waste Management Specifications • Develop construction waste management (CWM) specification language for all relevant sections – Consult DDC spec and modify it for your project. Requires minimum of 50% recycling. – MasterSpec addresses only on-site separation. • Integrate into project spec and sub-contractor agreements • Emphasize reporting and submittal requirements Construction Waste Management Plans & Forms • It’s all about focus and record-keeping. • Provide templates, but review work products and require revisions, if needed. • Require demo & CWM plan from GC (overall responsibility) and CWM plan from key contractors - HVAC, Plumbing, Electrical. • Decide on reporting in weight or volume (weight is typical) • Require to-date accounting and detailed record- keeping Typical Form • Date • Ticket # • Subcontractor • Container Volume (Cu Yds) • Total Weight (Tons) • Material Types • Estimated % of Total Load • Weight of Recycled & Landfilled Material • Material Recipient Waste Management Sample Form ________________: Project Demolition and Construction Waste Management Log - SAMPLE Recycled Materials (Off-Site Sorting) Period Documented: June 30, 2004 - July 30, 2004 Total Weight of Weight of Container Weight of Estimated % Recycled Landfilled Volume Refuse Material Types of Total Load Materials Material # Date Ticket # Subcontractor (Cu.

About 28% of these materials were recycled, including 6 tons of paper and 13 tons of ceiling tiles. • CEC salvaged approximately 20 truckloads over a two-month period. • However, the diversion rate could have been higher if there had been better coordination with other subcontractors.

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. LEED-NC 2.2 Construction Waste 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 percentage. • 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 Construction • 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.
