board feet (BF) of lumber were estimated to be available for reuse from the World War II

wood buildings then slated for demolition (Falk 2002).

 At Ft. McClellan in Anniston, Alabama, deconstruction and demolition was

performed on three barracks on site with varying degrees of mechanical and manual

labor. This project involves a life cycle assessment (LCA) to determine if the reuse of

wood salvaged from the deconstruction of the barracks is a viable alternative to using

virgin wood. The Environmental Protection Agency states an LCA "examines the

environmental releases and impacts of a specific product by tracking its development

from a raw material, through its production and to eventual disposal." An LCA was

performed on all four scenarios to compare the inputs and outputs of each scenario in the

form of environmental impacts, energy consumed and labor required. This project was

completed to help the DOD determine the square footage of barracks that need removal

and to compare and contrast environmental impacts of deconstruction and demolition.

This project will have a direct impact on the ability to plan the most environmentally

effective deconstruction of the barracks contained in EPA Region 4. This plan is

intended to aid the U.S. Army to meet its waste minimization goals, to provide materials

at lower cost for new construction on bases on or close to deconstruction sites, and to

increase the number of civilian jobs. The hypothesis of the project is that 100% manual

deconstruction will have the lowest environmental impacts of any of the four scenarios

because it is assumed the machinery will be used for the least amount of time and fewer

materials will be landfilled. Therefore the least amount of emissions should be produced

in the 100% manual deconstruction scenario.
