COST. There will be a cost associated with each method of building removal.
For comparison, costs relative to conventional demolition with a standard demolition
contract will be used as a benchmark. Total costs include the cost for demolition and
the cost for disposal. According to case study data, the cost of disposal can represent
up to 50 percent of the total demolition cost. This makes it desirable to explore
alternative methods to reduce disposal costs. Project objectives to minimize the cost of
building removal should consider initial costs, cost offsets, income potential, and life
cycle costs associated with each alternative.
3-1.1 Demolish (Cost). Initial costs for demolition are low. The cost of conventional
demolition (not including asbestos removal or tipping fees) ranges from to per
square foot of floor area. If all debris is landfilled, tipping fees may add to per
square foot of floor area.
Landfill tipping fees for C&D waste landfills vary widely depending on geographic
location. Studies show that the national average for C&D tipping fees has risen over the
past 20 years from .90 to .00 per ton. In Portland, OR, tipping fees for C&D
debris are high, around per ton. In densely populated areas like northern New
Jersey, tipping fees exceed 0 per ton.
Demolishing and landfilling building waste incurs significant life cycle expense to the
government as landfill space diminishes. The cost of managing and maintaining
landfills, along with rising tipping fees, makes this option the least preferable.
3-1.2 Recycle (Cost). The cost of a recycling program includes payment of wages for
separation and removal of desired materials either on-site or off-site. Separating
recyclable materials on-site as they are removed from the building adds to the initial
cost, but increases the value of the recycled material. These additional costs to extract
materials range from
to per square foot of building area. The need for added
recycling collection containers at the site also increases costs. Table 3-1 lists rental
rates for dumpsters.

If waste materials are commingled for delivery to a materials recovery facility for
recycling, the costs associated with transportation are a significant part of the dynamics
