While the R.S. Means approach does not address deconstruction specifically, it does
provide labor costs associated with selective demolition tasks. For a more complete
cost estimate, refer to R.S. Means Building Construction Cost Data, 57th Annual Edition,
1999, R.S. Means Publishers, Kingston, MA.
The MCACES is a multi-user software program used for the preparation of detailed
construction cost estimates for military, civil works, and Hazardous, Toxic, and
Radiological Waste (HTRW) programs. The supporting databases include a unit price
book (UPB), crews, assemblies, labor rates, equipment ownership schedule costs and
models. All databases work in conjunction with each other to produce a detailed cost
estimate. For additional information on the MCACES program, call or e-mail Jim
Nichols, CEHNC-ED-ES-A, at (256) 895-1842 or:

The JOC technique is based on a comprehensive set of general specifications and a
related Unit Price Book (UPB) adjusted for the area where the work will be performed to
reflect the cost and type of work anticipated. The UPB contains between 40,000 and
60,000 priced line items, organized in 16 Construction Specification Institute (CSI)
divisions, which, when factored by the contractor's pricing coefficient, are used to
establish firm fixed price delivery orders under the contract. For additional information
on the JOC program write or call Marie Raglind, CEHNC-CT-S, at the U.S. Army
Engineering and Support Center, Huntsville, AL (256) 895-1139 or e-mail at:

The MCACES databases and the JOC book list specific demolition jobs with the cost
and time requirements. The JOC also includes an added line item for the cost of
demolition and removal before selective remodeling tasks. The labor and cost required
for a salvage or deconstruction operation can be calculated using this data.
3-3 QUALITY / RESULTS. Future plans for the use of the site may affect the
selection of the method for removal. Mechanical equipment may be required for
cleaning up the site and restoring it to grade. The quality of work and results will vary
for each alternative method of building removal and for each building type. If
performance objectives are based on volume of waste reduction the following results
can be expected for each building type.
Brick or concrete structures generate about 3.0 cu ft of demolition debris per square foot
of floor area and wooden structures generate about 4.5 cu ft of demolition debris per
square foot of total floor area. A predominately brick structure can contain up to 80
percent brick by volume. Thus, an active brick-salvaging program could eliminate much
of the solid wastes resulting from demolition of this type of structure. For concrete
structures, approximately 50 percent of the demolition waste is composed of concrete--
--most of which can be recycled and reused. A "typical" WWII barracks, which is a
predominately wood structure, contains up to 90 percent wood. A careful salvaging
operation can provide high-quality lumber and reduce solid waste generation.
