- W843944857 abstract "Both construction Waste Minimisation (WM) and construction procurement activities playan effective role in attaining sustainability by giving due consideration to theenvironment, community and social conditions in delivering built assets. The constructionindustry has a major impact on the environment, both in terms of resource consumptionand increasing waste production. Recent figures published by the UK government revealthat construction and demolition activities produce approximately 32% of total wastegenerated: three times the waste produced by all households combined. However, thecurrent and on-going research in the field of construction WM and management focusesmainly on onsite waste quantification and management; and stakeholders‟ sourceidentification. Little research has been undertaken to evaluate the relationship betweenConstruction Procurement Systems (CPS) and construction waste generation. However,literature emphasises the need for research in this context.This research aims to develop a Procurement Waste Minimisation Framework (PWMF)to enhance WM practices by evaluating the relationship between CPS and constructionwaste generation. Objectives of the research include: examine construction WM drivers,WM approaches, waste origins and causes; critically review and evaluate current CPSand sustainable procurement practices in the UK; assess the relationship between CPSand construction waste generation; investigate and synthesis Procurement WasteOrigins (PWO); examine the most suitable CPS that could potentially embed and sustainWM; develop and validate the PWMF.This research has adopted a survey research design and mixed methods sequentialprocedure. Data has been gathered through a cross sectional, self-administered postalquestionnaire survey (N=258 distributed, n=65 received) and semi-structured interviews(N=17) with procurement managers and sustainability managers from the top 100 UKcontracting organisations and quantity surveyors from the top 100 UK quantity surveyingorganisations. Data analysis techniques include: descriptive statistics; non-parametrictests; and constant comparative method. The PWMF has developed based on thefindings of literature review, questionnaire survey and semi-structured interviews andadopting key concepts of problem solving methodology. The PWMF validation methodincludes: validation questionnaire (N=8) and follow-up semi-structured interviews (N=6)with procurement managers, sustainability managers and quantity surveyors. Key findings which emerged from the study include: CPS do have an impact on wastegeneration in construction; integrated CPS have major potential to integrate WMstrategies; four PWO identified (i.e. uncoordinated early involvement of projectstakeholders; ineffective communication and coordination; unclear allocation of WMresponsibilities; and inconsistent procurement documentation) and associated sub-wastecauses; and the developed PWMF enables to diagnose potential waste origins andcauses, and WM improvement measures for design and build projects. The study hasmade recommendations which, if adopted, will lead to significant improvements in WMpractices and sustainable procurement practices in construction. The content should beof interest to contractors, clients, and organisations dealing with procurement, waste andsustainability." @default.
