Demolition or Deconstruction?

Posted by:

Demolition and Deconstruction – aren’t they effectively the same? In a sense yes, as each requires the removal of a building and/or its contents. But this is where most similarities end – here one day and gone the next day (or two…). Demolition is the destructive removal and disposal of the building and/or contents with a total disregard for material salvage. Tear it down, toss the materials in a dumpster and transport everything to a landfill for disposal. On the other hand, Deconstruction selectively dismembers the materials that make up the building. Today Deconstruction is “green speak” for the removal of materials with the intent to reuse, recycle, or incorporate into a Waste Management Plan (WMP). 

What are the issues to consider when determining whether to select Demolition or Deconstruction? There are 2 fundamental factors to consider – costs and the environmental benefits associated with Deconstruction. First is the cost factor, and this can be somewhat difficult to accurately assess. Some studies show the cost to be 2 to 3 times as much for Deconstruction as opposed to Demolition. However, with Deconstruction you can factor in adjustments such as the market value and after-tax benefits of the salvaged materials. The leading authority on Deconstruction and Reuse is the Environmental Protection Agency (EPA). The EPA has recently focused a great deal of attention on Waste as it relates to Resource Conservation. Or as the EPA refers, the 3 Rs – Reduce, Reuse, Recycle. Additional information relating to cost comparisons can be reviewed at these sites: The ReUse People and Building Abatement Demolition Company, Inc.

Builder Magazine has an article titled Picking Up the Pieces that exemplifies the many benefits of sustainable deconstruction. The article follows the process of clearing an urban infill lot for the New American Home 2011.
