PROJECT SCOPE. The scope of a project will affect the viability of each
method of building removal. Depending on the method of building removal, there will be
certain project constraints. An installation or facility can package projects to optimize
the alternative methods. In most cases, the most successful strategy of building
removal will involve a combination of demolition and deconstruction to recycle and
recover useful materials.
4-1.1 Demolish (Project Scope). The scope of a project has no impact on the viability
of landfilling debris from demolition.
4-1.2 Recycle (Project Scope). A project in which materials are recycled instead of
landfilled is viable if the scope of the project is such that there is a high yield of materials
for reprocessing. The overall size of the demolition project affects the feasibility, but the
success of a recycling operation will also depend on the available recycling facilities in
the area. Lack of these facilities in a project area may make the recycling of some
materials expensive and/or impractical. The economies of transporting the materials
long distance must be weighed against local disposal.
4-1.3 Recover (Project Scope). A recovery operation is generally effective if the
scope of the project contains a large square footage of building to be removed. Larger
projects can take advantage of economies of scale to reduce the extra labor costs of
on-site preparation and save on landfill fees. Success will depend on the condition and
the quantity of the recovered materials. Recovery is feasible if the total value of the
items removed, plus the avoided costs for landfill disposal, compensates for the added
cost of removal and storage.
4-1.4 Deconstruct (Project Scope). Buildings should be identified and deconstructed
for their suitable components. Warehouses and certain types of industrial buildings are
often good deconstruction candidates, since they are relatively simple structures with
few interior partitions and are often unpainted. Valuable materials, (e.g., wood) are
relatively easy to access, debris is minimized, and LBP is less likely to be an issue.
Barracks are generally the second most desirable group of buildings to deconstruct
since they are also relatively simple. Although offices and residences are usually less
desirable structures, they should still be surveyed for deconstruction since some
structures may contain valuable materials or fixtures. Case studies show that a scope of
less than five buildings (approximately 10,000 total SF) is still sufficient to attract
participation in a deconstruction operation. On the other hand, if a great number of
buildings are to be removed at one time (hundreds), the glut of recovered materials may
depress resale prices, thus inhibiting economic benefits.
