Deconstruction is the systematic dismantling of a structure or its parts in the reverse order of construction. This method is used to salvage the building components, retain the highest value of the materials through reuse and/or recycling, and is an environmentally friendly alternative to demolition.

Types of deconstruction:

Material salvage: select components and features are removed from the building prior to building strip-out or removal.

Partial deconstructiona portion of the building, either particular segments or the entire interior, are removed prior to renovations or full removal.

Full deconstruction: the entire building is removed to the foundation piece by piece.

Why Deconstruct?

The method of deconstruction can be used in any situation that traditional demolition would be used for: preparing a building for renovations or a change of use, replacing outdated components, or fully removing an unstable or vacant structure. There are many benefits to deconstruction!

Environmental benefits:

  • An environmentally friendly alternative to traditional demolition because it reuses materials that would normally go into landfills or illegal dumping grounds.
  • Conserving our natural resources by reducing the demand for virgin materials.
  • Cleaner and more organized than traditional demolition because worksites are contained, carefully controlled and typically do not require heavy machinery.
  • Safer than demolition because the goal is to gently remove materials in one piece

 

Economic benefits:

  • There’s value in reclaimed materials: resale, remanufacturing, creative reuse
  • Reduced disposal costs
  • Career development – local economy and tax base; industry building;
    • Labor intensive: deconstruction crews
    • Recycling and reuse businesses
    • tools, services, and transportation

Social benefits:

  • Job training: job skills, decon/ salvage knowledge, hazard abatement
  • Maintain cultural and historical features of communities through material reuse
  • Increase the availability of affordable building materials for renovations and development
  • Giving artists and craftspeople new mediums to express their creativity.

Opportunities in Philadelphia:

  • Deconstruction is a labor-intensive process that is a great vehicle for job training – providing skills in an emerging industry, and other building trades, through hands-on experience.
  • By expanding the deconstruction and material re-use industries, we can create jobs that can help people support themselves and their families while contributing to the local economy.
  • There are over 40,000 vacant properties in Philadelphia. These properties drive away investment, attract crime and drag down property values city-wide by an estimated $3.6 billion. However, these spaces contain forests of lumber and mountains of bricks – raw materials that can generate value through re-use in building renovation, new construction and in other industries.
  • Philadelphia recently became the largest city in the country to pass land bank legislation, which is aimed at quickly developing its nearly 10,000 city-owned properties.
