The building deconstruction process and the debris trail : towards a dynamic model

Inacio, MFM

Abstract

Waste production and management problems have increased in this century. Population growth and consumption patterns in developing societies are associated with this growth. During the last decades, some world organisations have contributed to a global discussion and common resolutions. Concerns about the environment and sustainable development have been soundly highlighted. The European Union through its five Environment and Development Programmes as well the Directives and other special Regulations have responded that Agenda 21.

The complexity and historical context of integrated and sustainable waste management is studied within the context of the construction industry in Portugal. International experience and knowledge were also drawn upon to add to the local knowledge. The study classifies the debris trail. The deconstruction process is studied in order to illuminate the relationship with the nature of the debris trail. This is the core of the research which seeks to make a contribution to the understanding of this relationship and forms the basis for the development of a dynamic construction and demolition estimating and assessment model.

The work is based on case studies derived by observation from five complex and holistic case studies in Lisbon, cases studies reported from other countries and from work by others undertaken in France. Soft Systems Methodologies are used to illuminate the qualitative concerns. The quantitative information from practice is placed along side the qualitative data to give further insight into the issues being studied. The difficulties of insufficient actor involvement and participation in the process are also discussed.

Systems Dynamics methodologies are used to define a dynamic model using data from the sources referred. The model is intended to assist the assessment and estimation of the characteristics of the debris trail. The output of the dynamic model will contribute to a national strategy and plan for the construction and demolition waste stream in Portugal within the context of European Union strategies and guidelines.
