“…The survey data indicate that more dissemination of tools is required, despite the link on the Catalan Waste Agency's website to a computer application for simulating the quantity and type of waste generated in construction sites (ITeC, 2013). In this sense, results obtained by Wu et al (2014) about C&D waste quantification methodologies could be useful. Construction companies also advocate durable constructions (eliminating the use of prefabricated units) and the promotion of more sustainable techniques and systems in new-start construction projects such as prefabricated elements along the lines of Lachimpadi et al (2012).…”

In this paper, the implementation of effective waste management practices in construction projects and sites is analyzed, using data from a survey answered by 74 Spanish construction companies based in Catalonia. Most commonly implemented practices were found to be on-site cleanliness and order, correct storage of raw materials, and prioritization of the nearest authorized waste managers. The least widespread practices were the use of a mobile crusher on site, the creation of individualized drawings for each construction site, and the dissemination of the contents of the waste management plan to all workers, to help them to meet its requirements. Waste regulations for construction and demolition, and the corresponding construction waste management facilities, were designed before the recession in the Spanish construction sector. Current waste generation rates are still below predicted levels, and the infrastructure was designed for five times more waste generation. Even so, the percentage of reused and recycled waste currently amounts to 43%. Survey respondents highlighted various instruments and measures that would make the management of construction and demolition waste more sustainable. Most of the opportunities identified by construction firms are within the scope of government and related to a combined system of bonus and penalties and the establishment of environmental awareness and training programmes for all the stakeholders. Within the scope of authorized waste managers, firms suggested improvements such as the standardization of fees, a reduction of the time until the issue of waste management certificates, a higher number of inspections, and a change in the current model of a few large construction waste management facilities. This research is useful to better understand the current status of construction and demolition waste management in construction projects and sites. Thus, the results of this research will guide policy makers and relevant stakeholders such as contractors, clients, architects and engineers to achieve the EU target of recovering 70% of construction and demolition waste in 2020. In this sense, reliable information can help governments and professional associations to set future C&D waste management regulations, training programmes and dissemination tools, inspections, etc.Peer ReviewedPostprint (author's final draft

“…Waste estimation tools provide the essential basis for understanding causes, types and quantities of construction waste arising from building designs (Wu et al, 2014). Prior knowledge of waste in a project will enable assessment of their management possibilities, including the waste prevention (Llatas, 2013).…”

Citation: AbstractReduction in construction waste is a pressing need in many countries The design of building elements is considered a pivotal process to achieve waste reduction at source, which enables an informed prediction of their wastage reduction levels. However the lack of quantitative methods linking design strategies to waste reduction hinders designing out waste practice in building projects. Therefore, this paper addresses this knowledge gap through the Keywords:Building design waste reduction model; design waste reduction strategies; design waste reduction level quantification; design waste reduction assessment.LLatas, C and Osmani, M (2016) Development and validation of a building design waste reduction model, Waste Management (In Press)

“…Many models have been established over the last decade to determine the project waste quantities [8,9]. The present authors, together with others, have also developed a quantification model to estimate the type and quantity of waste generated by different construction projects, such as new buildings, demolition, renovations and alterations [10].…”

Eco-efficient rehabilitation of buildings and neighbourhoods should include strategies to reduce the potential environmental impact of buildings under consideration for demolishment. In this case, good construction and demolition (C&D) waste management can represent a doubly eco-efficient approach: advantage is taken of much of the building and the volume of waste is reduced during construction and demolition work.Construction and demolition waste management in emergency situations is a subject yet to be studied in the construction sector. This kind of work, although not very common, involves major building damages and the need for punctual, partial or total demolitions. The amount of C&D waste can be a major problem to deal with, and its management during the critical first phases can determinate the progress of the rehabilitation.Conditioned by a greater number of factors than normal construction works, the lack of time for the identification, quantification, and evaluation of C&D waste renders this type of extremely useful study.In this work, from the case study of the emergency repair of a residential building of 40 dwellings in Seville (Spain) seriously affected by a soil displacement, Generated C&D waste are identified and the waste reduction techniques used are shown. These techniques contributed to achieve the planned objectives and to control in advance the cost.Finally, the most important data, C&D waste quantification and the managing cost are presented in order to serve as reference for similar circumstances in the future because there areno clear references to be used.
