What is Deconstruction?
• Deconstruction = dismantlement, unbuilding, reverse construction, etc.
• Deconstruction is a tool for the salvage of reusable building materials from remodeling or building removal.
• Deconstruction can involve the selective salvage of materials OR as a means to remove the whole building.
• Deconstruction can be an alternative to demolition, but can also be part of a building removal process that involves demolition.
• Deconstruction should be the first step in the building removal process.
www.fpl.fs.fed.us www.bmra.org
Why Salvage & Reuse Building Materials?
• Avoid landfill waste.• For every ton of material reused, a ton less goes into our
landfills.
• Help reduce the consumption of new resources. • For every pound of material reused, about 16 pounds of
raw material are not mined, harvested, or manufactured.
• Reduce pollution & carbon impact.• By reusing, we avoid the pollution and greenhouse gas
emissions associated with product manufacture and transport.
• Utilize a valuable resource• Functional and high value materials exist in the buildings
we tear down every year.
• Help transform distressed neighborhoods into sustainable communities.• Deconstruction keeps the value of these materials in the
neighborhood, an asset in community redevelopment.
www.fpl.fs.fed.us www.bmra.org
Why Salvage & Reuse Building Materials?
(cont.)
• Help expand job opportunities, small business creation, and workforce development skills.• The number of reused building materials centers has
grown rapidly over the last 15 years, estimated at over 1000 nationwide.
• Deconstruction and building materials reuse offers job skills that can be used in many other industries, including construction and retailing.
• Deconstruction offers opportunity for those with little or no job skills to enter the workforce.
• Supports the tenets of green building through materials reuse.• US Green Building Council’s LEED for Homes program
offers up to 6.5 points for materials reuse from a total of 8 for Environmentally Preferable Products (MR 2.1).
Current BMRA Activities
1. Training Development
2. EPA RRP Rule
3. DECON11 Conference
www.fpl.fs.fed.us www.bmra.org
Training Development
• Development of a standardized deconstruction training curriculum is in progress.
• This curriculum would reflect the collective knowledge of our membership and would be developed and reviewed by the deconstruction industry.
• Curriculums are being developed for use at both the community college level as well as for municipality-based trainees.
• Current development partners include Iowa Central Community College and the City of Seattle.

EPA’s RRP Rule
• Lead: Renovation, Repair, & Painting Rule
• Requested EPA to clarify Rule and its impact on salvage activities.
• Remodeling and painting contractors must be trained by a certified EPA firm and use lead-safe work practices and procedures: • Contain the work area.
• Minimize dust.
• Clean up thoroughly.
• Test.
www.fpl.fs.fed.us www.bmra.org
Questions Posed
1. Does the RRP Rule apply to buildings slated for removal?
2. Does the RRP Rule apply to salvage in remodeling projects?
3. Does the RRP Rule affect the disposition of materials removed?
www.fpl.fs.fed.us www.bmra.org
EPA’s RRP Rule
BMRA Interpretation:
1. The RRP does not apply to buildings slated for removal.
2. The RRP does apply to any remodeling project, regardless if salvage takes place or not.
3. The salvage and removal of materials or components coated with LBP is outside the scope of RRP.

www.fpl.fs.fed.us www.bmra.org
Ongoing Research
• Environmental impact of reusing
lumber and wood strip flooring.
• Reusing lumber in construction.
www.fpl.fs.fed.us www.bmra.org
Environmental Impact of
Reusing Wood
• Life Cycle Inventory (LCI) Analysis
• Objective is to evaluate the environmental
consequence of reusing wood framing and
wood flooring compared to using a similar
“new” product.
• Cooperative study between FPL, Athena
Institute, US Army CERL, UW.
www.fpl.fs.fed.us www.bmra.org
Life Cycle Assessment
• Methodology to assess the impact associated
with all the stages of a process from-cradle-to-
grave (i.e., from raw materials through materials
processing, manufacture, distribution, use, repair
and maintenance, and disposal or recycling).
• LCA is composed of individual LCIs (interlinked).
Cradle-to-Grave Life Cycle Assessment
Composed of individual life-cycle stages (i.e. LCIs)
www.fpl.fs.fed.us www.bmra.org
Project Steps
1. LCI of new lumber & flooring
• Already developed by CORRIM (www.corrim.org)
• US LCI Database (www. nrel.gov/lci)
2. Develop LCIs of reclaimed lumber & flooring
• Survey of industry
• Quantification of processes/energy demands.
3. Compare 1 & 2

Next Steps
• Quantify Carbon Impact
• Forest sequestration
• End-of-life scenarios (wood as fuel,
landfilling)
www.fpl.fs.fed.us www.bmra.org
Reuse of Lumber
1. Two product types to consider
a. Large timbers
b. 2-by lumber
2. Building Code approval required for
both.
www.fpl.fs.fed.us www.bmra.org
Large Timbers
• Either end up as:
• Timber frame construction.
• Flooring or other non-structural use.
Timber Frame Construction
www.fpl.fs.fed.us www.bmra.org
2-by Lumber
• Problem
• Marketing of reclaimed 2-by lumber is
hampered.
• Acceptance is inconsistent.
www.fpl.fs.fed.us www.bmra.org
How to Solve Problem?
1. Test reclaimed lumber to determine:
a. Residual engineering properties.
b. Effects of damage on properties.
2. Work with wood industry to draft
appropriate amendments to grading
rules and design standards.
Testing
1. Graded 4000 pieces
of lumber from 5 sites.
2. Tested over 2000
pieces of lumber to
failure (1200 full
sized).
3. Analyzed results and
compared to existing
data bases.

Rules/Standards
www.fpl.fs.fed.us www.bmra.org
What’s Next?
1. Finalizing recommendations to grading
agencies via a white paper.
2. Hope that the wood industry moves
forward to approve.
www.fpl.fs.fed.us www.bmra.org
Till Then?
1. West Coast Lumber Inspection Bureau
(WCLIB) will regrade reclaimed
lumber.
2. They will also train graders to do so.
www.fpl.fs.fed.us www.bmra.org
Future Scenarios
1. Lumber will have to be regraded.
2. Form co-ops to pool enough lumber to
minimize regrading costs.
