Construction and

Demolition Waste

Management Programs

The campus perspective…• Residence halls• Houses• Restaurants & dining halls• Medical clinics and hospital• Office buildings • Classrooms• Science research labs• Retail stores• Facilities maintenance shops• Service station• Theatres• Indoor and outdoor stadiums• Performance halls• Power plant & cooling towers• Museum• Planetarium

UNC Chapel Hill Facts & Construction Information:• One of 16 schools in the North Carolina state system• 26,800 students; 8,000 on campus residents• 3,100 faculty and 5,000 staff members• $500 million bond

($1.5 billion total)• Master plan process• 6.5 million square feet in

construction or design• 4.5 million square feet

remaining• 153 projects active capital projects• More than 51 projects in construction

Before… After!

• Renovation of existing buildings• Demolition of existing buildings• Construction of new buildings

Hierarchy -• Salvage

• Reuse in project• Reuse on campus• Reuse elsewhere

• Recycle• Reuse in project• Reuse on campus• Source separation• MRF

• Landfill• Construction and demolition• Land clearing and inert debris• Hole in someone’s field or gravel quarry!

Movables

Fixtures

Building components

Determine what can be reused, salvaged, or recycled during design:• Walkthroughs• Inventory• Project Documents (drawings and specs)

Project specific list shown in documents (specifications and drawings):

• 01505• Required by law (Orange County, NC)• Required for the project• Suggested

• 02070• Selective demolition

• Material or item-specific specifications• Slate, ceiling tile, brick

Meetings:• Pre-bid• Pre-construction• Solid waste planning meeting• Progress and follow up• Site inspections

Planning and implementation:• Draft plan• Final plan

Documentation• Monthly solid waste management plan reporting• Selective demolition reporting• Project close-out reporting • LEED documentation

Case studies…• Movable• Fixtures• Building structure components

Movable Asset Salvage• 120 student desks to an

Emerson Waldorf school

• 250 student desks to the Nash County Boys/Girls club

• Stacking chairs to the Zen Center.

Movable Asset Salvage -• Construction waste?

• It is when it’s left for the contractor to deal with it!

• There are markets for these things…even the bones!

This is what happens when there’s no plan… hundreds of beds end up in a pile,and then the dumpster. And our office pays the bill.

Fixed Asset Salvage• 211 units of library shelving to

schools and libraries

• 300 seats from Memorial Hall to a community theater

• An Emerson Waldorf school filled a 24 ft. truck with wallcabinets, bookshelves, chalkboards, and projector screens.

Fixed Asset Salvage – Chase

• Dining facility demolition

• Advance planning fell through

• Last-minute scramble with creative solutions and team work

Fixed Asset Salvage – Chase

• Surplus moved 20 truckloadsand received an additional 2 semis full of equipment, fixtures, and dishes.

• Surplus retail store estimates sales to date of approximately $8,000.

• Abatement contractor not having to deal with equipment = priceless.

Building ComponentsSALVAGE

• Slate roofing tiles• Flooring

RECYCLING• Metal• Ceiling tiles• Concrete, brick, masonry

Building Component Salvage – Woolen Gym

• 30K sq ft went to a salvage company. • They sold some, and are turning

the rest into tables, plaques, and bar stools.

• They are selling them as official memorabilia.

• Habitat for Humanity got 5K sq ft and made $10,000 on it.

• Small portion reused on campus.

Building Component Salvage– Phillips Hall Roof

• Purchased 26 squares out of 200 -nearly 90% of the existing slate was reused.

• New slate - $200 per square*

• Reused slate - $65 per square*(includes labor to salvage)

• Reuse saved $63,500 in material purchases

• $300 - $2,000 saved in averted tip fees.

*According to estimates in the design phase

Source Separation – Peabody

• 380 tons total debris

• 150 tons diverted

• 40% recycling rate*

• Materials recycled include: • metals (ductwork)• ceiling tile• drywall• brick/block/porcelain

• Project Supt. attests that he increased his profit marginby recycling.

Source Separation– Chase Dining Hall

• Good job on pre-demo salvage

• 16% recycling

• 84% landfilled – ouch!

• Triple the normal amount of rebar.

• No special equipment for processing concrete

• Gravity method--picking up concrete and dropping it.

Material Recovery Facility – Manning Steam Tunnel ph. 2B, 9/05 (estimated)• 2.8 tons wood• 3.45 tons metal• 1.0 tons concrete• 0.9 tons cardboard• 0.5 tons plastic• 5.6 tons landfill

61% diverted from landfill

Problems encountered:• Getting buy-in and understanding of the ‘big picture’

• Reporting• Getting information.• When we need it• In a consistent format across projects• Reliable information (matching weight tickets to the job)• Accuracy (volume to weight conversion)• Compiling and analyzing data

• Timing• Can’t delay the project• Small window of opportunity • Schedules shift

• Labor for salvage

Pieces of the capital project puzzle…Design Stages (review at each phase!)

• Schematic• Design Development• Construction Documents• (Bid Documents)

Construction• Abatement• Demolition• New Construction/Renovation

At UNC, a project manager works with the architect/design firm until the project goes into construction. Once in construction, a UNCconstruction manager becomes the university point of contact for the project.

Stakeholders and participants• UNC

• Occupants, Board of Trustees, and Town• Project Manager (until construction starts)• Construction Manager • Environment Health and Safety• Office of Waste Reduction and Recycling• Facilities Maintenance Shops (salvage)

• Architect/Design Firm• Construction Manager at Risk• Abatement Contractors• Contactors and their subs• County solid waste officials (local regulations)• Surplus, non-profits and salvage firms

Waste management by design!

Planning for recycling and waste removal in the finished building:examples of what can go wrong!

Planning for recycling and waste removal in the finished building:

• Animal Bedding• Bottles & Cans • Cardboard• Food Waste • Grease• Newspaper & Magazines • Office Paper• Scrap Metal • Trash

Waste management planning based on

building use and waste generation!

Exterior collection and removal of trash and recycling:

• General Configuration• Pad Dimensions• Containers & Equipment• Screen Walls• Access • Concrete Info• Bollards• Ramp• Drainage• Lighting• Electricity (Compactors)

Screen Walls:

Containers and Equipment:• Pricing• Vendors• Dimensions• Specifications

Service Vehicles:• Turning radius• Overhead clearance• Length• Weight

Everything the designer needs in order to build or order these cabinets!• General Configuration• Color and finish information• Dimensions• Placement• Closures• Labels• Handles• Hinges• Wheels

Walkway recycling for the landscape architect:• General Configuration• Pad Dimensions• Placement and Access • Labels• Cost and supplier information

Don’t assume that you will still be able

to get where you need to go during construction!
