* Deconstruction and the resulting reuse of building materials results in avoidance of

 some of the costs of landfilling, primarily transportation and tipping fees.

* Recovering materials may generate a credit or otherwise subsidize the overall

 building disposal costs. A generated credit would allow the owner of the

 deconstructed building to receive money or materials from the user of the recovered

 materials.

* Landfill failures can result in remediation costs being assigned to former landfill

 contributors. By reducing landfill use, there could be a reduced future liability

 (Falk and Lantz 1996).

* Due to the increasing cost of materials manufactured with virgin materials, recycled

 materials are becoming much cheaper in comparison.

* Salvaging reduces the total cost of materials since only the cost of removal,

 refurbishing, and transport is incurred by the salvage (NAHB 2003).

* The availability of high-quality virgin materials for the manufacture of building

 materials is decreasing. In many cases, the sources of raw materials are great

 distances from installations or building projects, and high transportation costs make

 contractors look for a local replacement.

* Many state and regional waste authorities restrict the disposal of bulk waste, such

 as furniture, appliances, and building equipment, to special solid waste handlers or

 landfills. This, in turn, has driven up the disposal tipping fees. In most cases, any

 level of salvage reduces the cost of disposal.

* Timber that is recovered properly from older buildings is gaining acceptance in

 meeting the demand for large old-growth timber (Falk, R. and Lantz, S. 1996).
