1 Deconstruction: A Local Government Model Wayne Fenton Orange County Public Works, Hillsborough, NC

2 What is Deconstruction? Deconstruction is the process of selectively and systematically disassembling buildings that would otherwise be demolished to generate a supply of materials suitable for reuse in the construction or rehabilitation of other structures. Deconstruction differs from recycling in that recycling does not seek to capture building materials in a reusable form (i.e., whole bricks, blocks, clean, unbroken pieces of lumber, etc.)

3 A Brief History Orange County owns 34 buildings Buildings range in age from pre- Revolutionary war to modern structures

4 The Building Approximately 3,000 square feet

5 The Experiment A 1920’s/1950’s mixed construction structure housing a sheltered workshop Building located in heart of historic district Sat vacant for several years after suffering severe storm damage Options considered

6 The Process Project approved by BOCC Purchasing Dep’t persuaded Bid-process tailored Seasoned local deconstruction specialists hired Process documented

7 Desired Project Outcomes Removal of unsafe structure Capture of valuable materials, especially for use in other similar vintage structures Demonstrate feasibility of process Provide skills enhancement opportunities Document the process: –To develop promotional video –To develop basic “how-to” video

8 Materials Recovered 39+ tons of building materials recovered for reuse through deconstruction

9 Recovered Materials BRICKCONCRETE BLOCKS DIMENSIONAL FRAMING LUMBER OAK TONGUE & GROOVE FLOORING PINE TONGUE & GROOVE FLOORING WINDOWS DOORSWOOD SIDINGPINE WALL PANELING

10 Materials Recycled 6 tons of metal 1 ton of white goods 140 tons of concrete

11 Waste Generated Less than 100 tons of waste generated by deconstruction required disposal Primarily rotted wood, mixed composition items, sheetrock, shingles

12 Benefits of Deconstruction

13 Economic Cost of deconstruction can be less than cost of demolition Salvaged materials have a value Cost avoidance in tipping fees Preservation of landfill space Job-skills training

14 Environmental Preservation of landfill space Resource conservation Deconstruction a cleaner technology than demolition – less noise, air pollution

15 Educational Governments should lead by example Act as a catalyst to contractors, facility owners/managers Be a model for other governments

16 Cost Benefit Analysis Demolition Costs Estimate: $50,000 Deconstruction Costs Actual Expenditures: $37,929 Savings Salvaged Materials Value: $37,130* Landfill Fees Avoided: $1,600 * Based on local vendor estimate

17 Measuring Success Structure successfully and safely removed Some materials have been reused in other projects Demonstrated feasibility of deconstruction option Provided temporary workers with enhanced skills – two hired by County, one still employed Promotional video complete & limited distribution

18 The Video High quality, low budget 16 minutes running time
