Abstract:Currently, 95% of the construction waste is recycled, but 70% of this recycling can actually be defined as downcycling. This implies a massive loss of value, which can be altered by moving towards deconstruction instead of demolition. This research looks into the preconditions for this transition. The goal of the research is to analyse the most important preconditions per value retaining deconstruction strategy. Literature research, validated by case studies, generated eight main preconditions. Three categories are identified: direct influence, future influence and sector influence. Direct influence means the preconditions can be met in present projects by an individual construction company and contains preconditions ‘building sequence information is archived to share with future demolition contractor’ and ‘storage facility is available’. Future influence means construction companies can take action now, to meet preconditions in the future and contains preconditions ‘certainty on deconstruction time and recovery rate’, ‘objects are relatively easy to deconstruct’, ‘elements with standardized dimensions’ and ‘material is of high quality’. Sector influence means actions of the whole construction sector are necessary to meet the preconditions and contains preconditions ‘second hand materials are demanded’ and ‘financial case is clear and profitable’. Lastly, in the case studies, the deconstruction strategies (reuse, remanufacture and recycle) are used parallel to each other.
