Data Inventory

 Both primary (derived directly from the deconstructed and demolished barracks)

and secondary (derived from literature and regulatory agency publications and databases)

data were collected and databased in LCA software, SimaPro 5.1 (PRe Consultants,

Ameersfort, The Netherlands). SimaPro contains inventory data that has already been

gathered for common products and processes in databases created by ETH-ESU (Uster,

Switzerland), Buwal 250 (Bern, Switzerland), and Franklin Associates (Prairie Village,

Kansas, USA), among others (Goedkoop and Oele 2001). As previously described, the

primary data collected included the amounts of hazardous, salvaged, recycled and

landfilled materials, the amount of time each piece of equipment was used, the number of

workers, and the worker labor time. In addition, the weights of salvaged and landfilled

materials were found by weighing the hauling trucks before and after filling. The

secondary data included types of equipment and materials used (site-specific for project),

fuel type and requirements of each piece of equipment (JLG 2004, Bobcat 2004,

Caterpillar 2004, Grove 2004, Homelite 2004, Stihl 2004, DeWalt 2004), amount and

composition of leachate from all deconstruction materials (Jamback 2004), equipment

usage for production of virgin wood in the forest and at the sawmill (Long 2003),

emissions for production of bricks used in the barracks construction (EPA 1997),

recycling and producing steel (EPA 1986), diesel and gasoline fuel combustion emissions

(EPA 1995), data for the production of diesel fuel and gasoline (EPA 1995) and for the

U.S. electricity mix (SimaPro 5.1). The LCA compared the inputs and outputs of each

alternative scenario in terms of emissions, the value of the material, and requirements of

dollars, energy, and labor.
