  1. Hybrid Deconstruction: Commercial Case Study The slides and/or pictures contained in this PowerPoint document are the property of RE-USE Consulting and are not to be copied or reused with written permission.

  2. Barriers to Deconstruction – How far are we from zero waste? Fortunately…. • Estimate: 95+ % of people want deconstruction vs. demolition Unfortunately…. • Estimate: 95% of people do not want it to take much longer than demolition • Estimate: 97% of people do not want it to cost much more than demolition

  3. Barriers to Deconstruction – Is this how to compete with demolition?? • Strategy: Some deconstruction groups are ‘offering’ unusually large tax-deductions to ‘pay’ people to deconstruct (California is known for this) • Result: IRS has started an investigation into these non-profits similar to the car-donation scams a few years back and has threatened to shut them down and revoke their non-profit status • Strategy: Combine seeking government assistance to start and maintain program and sell public on the environmental benefits of deconstruction in order to get them to pay more • Result: Funding runs out or limits the operation’s growth and the public avoids guilt trip while continuing to buy the nice Sub-Zero refrigerator

  4. Mainstream Decon OUR GOAL : To make building deconstruction a mainstream choice for building removal. To do this we must overcome barriers to deconstruction.

  6. Demolition vs. Deconstruction Deconstruction Costs LABOR DISPOSAL Demolition Costs DISPOSAL LABOR

  7. The road to full deconstruction has many stops on the way. Demolition Deconstruction RE-USE Consulting Moving structures or preserving them in place is off the chart. Demolition is a dead end street for your community.

  8. Not just homes….

  9. Reversing the Flow Reduce waste Avoid producing new waste One pound of reuse avoids several pounds of waste associated with the production of one pound of new building materials One pound of reuse also avoids the reduction in energy that would have been used to produce new building materials • 1000+ cities that can support a reuse/deconstruction operation • They would be capable of diverting 2.5 to 5.0 billion pounds via reuse and recycling • Create 20-50,000 jobs • If reusing one pound of material avoids many pounds of waste, then why don’t we strive to make new buildings out of highly reusable materials?

  10. Betraying our mission The path to zero waste doesn’t start with zero waste Zero waste efforts have led to high priced projects.

  11. Designing for Deconstruction RE-USE Consulting’s new RE-Building Project • We are experimenting with keeping sections of the building intact (sometimes even including the drywall !) in order to build smaller structures out of them • By keeping them together we: • Preserve more of the embodied energy • Save time on both sides of the equation

  12. Designing For Disassembly Zero waste is impossible when waste is designed into new structures • Adhesives can ruin materials • (so let’s use them to our advantage - panelization) • Stricter codes limiting reuse; lack of time • (expedite permits when deconstruction is chosen) • Fasteners are one of the reasons buildings are not deconstructed • (new fastening systems and reuse options are on the way!)

  13. Designing for Deconstruction

  14. CASE STUDYCommercial Building Complex, Bellingham, WA

  15. Owner Involvement Base bid: demolition Alternate A: 50% landfill diversion (no concrete/brick allowed in calculations) Alternate B: Full building deconstruction, return materials to owner. The City decided on Alternate A. They asked for 50% diversion, but received 94% diversion for the same price!

  16. Recycled Materials Recycled Items Disposal items • Metal Carpet • Wood Torch down roofing • Painted Wood Vinyl tile flooring • Sheetrock • Foam Carpet Pad • Cardboard • Light ballasts/bulbs No concrete ‘allowed’- or rock, or brick, or meteors

  17. Stats – Diversion amounts • Garbage dumpsters less than 4 1/3 (about 25 tons) • Asbestos roofing 26 tons • Recycling dumpsters (280 tons) run from 9000-14000 lbs. each • Reusables: 48000 lbs semi 1+28000 lbs trailers + 47,000 lbs semi + 17000 lbs additional loads for a total of 140,000 lbs or 70 tons (or more)

  18. Stats – Balancing the checkbook • $118,000 initial bid + change orders • $42,000 in sales • $9000 in dump fees avoided by diverting material for reuse– enough for 200+ labor hrs. • 375 tons tracked – would have cost $31k in Bellingham to dispose of • Materials retail price was estimated at over $100,000 • What if it wasn’t a prevailing wage jobsite?

  19. Summary of findings • Balance of labor and value • Listen to Dave – sheetrock, tool choices • 401 tons – 94% on-site diversion rate without asbestos • Demolition Deconstruction contractor’s FIRST full decon job

  20. National Efforts To Promote Decon • CT – Decon Group to change laws regarding who can perform demolition and to redefine demolition • CA – IRS efforts (nationwide) to crack-down on deconstruction groups and their tax deductions – shuts down 1 group in CA • NY – Gov’t funding for recycling and reuse enterprises • OH – Multiple cities using stimulus money to promote decon • CO – Deconstruction surveys and more • OR – Funding for facilities and deconstruction projects • IL – Job training for the Olympic Games project and new Chicago deconstruction project (85 jobs for three years)
