When you’re done playing, put your stuff away…
In 1995, the US Army estimated 250 million board feet of lumber were available in its WWII wood buildings slated for demolition.

Three Deliverables:
1. Optimization Sequence2. Region IV Mentorship3. Life Cycle Assessment
What is Deconstruction?
§ Building disassembly to maximize the recovery of reusable and recyclable materials in a cost-effective, environmentally sound, and safe manner.
§ Pragmatic enabling of reuse/recycling of land, infrastructure, buildings, materials

Project Site:
Ft. McClellan
Scenario 1
In situ deconstruction of building in structural sequence
Scenario 2
Panelization of 2nd floor as one element and parallel deconstruction of two building halves
Scenario 3
Mechanical panelization of building then deconstructionof individual elements
Scenario 4
In situ deconstruction and panelization of major elements in sequence

Final Deliverable:
1. Optimization Sequence2. Region IV Mentorship3. Life Cycle Assessment
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.”
n U.S. Environmental Protection Agency
LCA Example: Pine & Fir Siding
Raw Materials
Energy
Water
Coproducts
Air
Water
Solid Waste
Other
Old Growth Forest Harvesting
Wood Siding Manufacture
Product Distribution, Use, Reuse
Disposal
Transportation
Denotes beneficial reuse of salvaged materials
Transportation
TransportationCosts: Labor, Capital, etc… Savings
Proposed Tasks
Develop a Database
n Region IV surplus facilities’ characteristics
n Information on the deconstruction processw Types and sequence of activities, total amounts of
salvage, total hours of hand/mechanical labor, total costs, etc.
Proposed Tasks continued…
Identify viable reuse optionsn New “markets” for salvaged
materials
Conduct LCA on virgin vs salvaged materials use in viable reuse applicationsn Economic, environmental,
social impact analysis
Research Needs from DOD
Information concerning all Region IV facilities available for deconstruction n Contacts with this informationn Meetings at the sites if necessary
Feedback!n Especially during the Scoping phase
Input/output data during Data Collection phase
Participation in regular progress report reviews
