The City of LethbridgeENVIRONMENTAL DECONSTRUCTION INITIATIVEINTRODUCTION ‘Deconstruction’ is the selective dismantling of building components, specifically for re-‐use, recycling, and waste management – “construction in reverse”, It differs from demolition where a site is cleared of its building by the most expedient means Contributes To Sustainability By; giving materials a new lifecycle, lowering the need for virgin resources, thus reducing energy and emissions from the refining and manufacturing process of new materials, reduces the need for transportation of raw and new materials both for manufacturing and post product delivery, provides local jobs, -‐ 3 to 6 workers for every 1 employed in a 2 comparable demolition project,

The City of LethbridgeENVIRONMENTAL DECONSTRUCTION INITIATIVE But the prime benefit of this innovation is that solidwaste from conventional demolition is diverted fromlocal landfills. construction and demolition (C & D) waste accounts forapproximately 20% of the solid waste stream at theLethbridge landfill, A landfills basic commodity is selling cubic meters of‘air’ which is especially relevant as C & D wastecompacts less than normal mixed stream waste, thusconsuming up to 25% more area. 3

The City of LethbridgeENVIRONMENTAL DECONSTRUCTION INITIATIVEECONOMIC POTENTIAL Varies from project to project. The amount of time and cost of labor can be a drawback. Harvesting materials from a structure can take weeks, whereas demolition may be completed in roughly a day. Some of the costs, if not all, can be recovered. reusing materials in future projects, selling reclaimed materials, donating materials for income tax write-‐offs, avoiding transportation and landfill “tipping fees” , 4

The City of LethbridgeENVIRONMENTAL DECONSTRUCTION INITIATIVE As the City of Lethbridge continues with this innovation we have found that the local contractor’s ingenuity in finding new uses for reclaimed materials is ever increasing and the City is benefiting greatly 5

The City of LethbridgeENVIRONMENTAL DECONSTRUCTION INITIATIVEPROCESS Hazardous materials are identified and properly abated to render a safe and clean site. A ‘waste streaming’ specialist is engaged, assess achievable goals, further aid the contractor in the successful diversion of C & D materials, monitor and record the disposal of all materials, prepare a detailed report of the projects success, 6

The City of LethbridgeENVIRONMENTAL DECONSTRUCTION INITIATIVE ‘Waste Streaming’ process, involves identifying and assessing various building elements so that prearranged ‘homes’ can be found for usable materials prior to even starting work. Quantifying waste material is based on a percentageof the C & D material weight of all; building materials, furnishings, equipment, site elements, such as parking lots, swimming pools,sidewalks, driveways, The successful contractor is awarded salvage of allmaterials, 7

The City of LethbridgeENVIRONMENTAL DECONSTRUCTION INITIATIVESUCCESS STORIES The City’s first waste streaming project was the 2007 deconstruction of a hotel constructed in 1889. Deconstruction was found to be a new method of building removal in the area and some project ‘growing pains’ were experienced. However through time, the local industry has gained a better understanding of this process and while each project is different, the percentage of successful diversion of materials has significantly increased. 8
