5 In 1995, the US Army estimated 250 million board feet of lumber were available in its WWII wood buildings slated for demolition.

6 Executive Order 13101: Greening the Government Lead Based Paint Asbestos Equipment costs Quantity of salvage for reuse/remanufacture Landfill capacity Safety time and costs Health and safety Labor skill and costs Base Commander Disposal Costs Transportation costs OSHA, EPA, State regulations Time on building site Time of entire process

7 UF Deconstruction Study Three Deliverables: 1. Optimization Sequence 2. Region IV Mentorship 3. Life Cycle Assessment

8 UF Deconstruction Study Three Deliverables: 1. Optimization Sequence 2. Region IV Mentorship 3. Life Cycle Assessment

9 What is Deconstruction? Building disassembly to maximize the recovery of reusable and recyclable materials in a costeffective, environmentally sound, and safe manner. Pragmatic enabling of reuse/recycling of land, infrastructure, buildings, materials

18 Project Metrics Time on building site Time of entire process Safety time and costs Labor skill and costs Equipment costs Transportation costs Hazardous materials abatement, handling, and disposal costs Non-hazardous wastes disposal costs Quantity of salvage for reuse/ remanufacture Quality or value of salvage for reuse/ remanufacture Project Site: Ft. McClellan

19 Scenario 1 In situ deconstruction of building in structural sequence

20 Scenario 2 Panelization of 2 nd floor as one element and parallel deconstruction of two building halves

21 Scenario 3 Mechanical panelization of building then deconstruction of individual elements

22 Scenario 4 In situ deconstruction and panelization of major elements in sequence

23 UF Deconstruction Study Next Deliverable: 1. Optimization Sequence 2. Region IV Mentorship 3. Life Cycle Assessment Commander

24 Region IV Mentorship Deconstruction Computer Model Team w/ University of Louisville Ft. Bragg, Ft. Rucker, others Deconstruction and Materials Reuse Conference, May 2003 EPA, FDEP, UBMA, CIB, CERL

25 UF Deconstruction Study Final Deliverable: 1. Optimization Sequence 2. Region IV Mentorship 3. Life Cycle Assessment

26 Definition of Life Cycle Assessment (LCA) examining the environmental releases and impacts of a specific product by tracking its development from a raw material, through its production and to eventual disposal. U.S. Environmental Protection Agency

27 LCA Example: Pine & Fir Siding Raw Materials Energy Water Costs: Labor, Capital, etc Transportation Old Growth Forest Harvesting Wood Siding Manufacture Transportation Product Distribution, Use, Reuse Transportation Disposal Coproducts Air Water Solid Waste Other Savings Denotes beneficial reuse of salvaged materials

28 Proposed Tasks Develop a Database Region IV surplus facilities characteristics Information on the deconstruction process Types and sequence of activities, total amounts of salvage, total hours of hand/mechanical labor, total costs, etc.

29 Proposed Tasks continued Identify viable reuse options New markets for salvaged materials Conduct LCA on virgin vs salvaged materials use in viable reuse applications Economic, environmental, social impact analysis

30 Research Needs from DOD Information concerning all Region IV facilities available for deconstruction Contacts with this information Meetings at the sites if necessary Feedback! Especially during the Scoping phase Input/output data during Data Collection phase Participation in regular progress report reviews

31 UF Deconstruction Study Review of Deliverables: 1. Optimization Options 2. Region IV Mentorship 3. Life Cycle Assessment coordinated with the University of Louisville, Kentucky P2 Center, Ft. Knox, CERL, EPI, EPA, FPL, FDEP
