Abstract
While it is recognised that Construction Procurement Systems (CPS) and waste reduction have an effect on achieving sustainability, little research has been undertaken in the evaluation of the impact of CPS on construction waste generation. The research presented in this paper aims to investigate the impact of CPS on waste generation. A postal questionnaire survey was administered to the top 100 contractors in the UK targeting procurement managers and environmental/ sustainability managers to obtain their views to evaluate current practices of CPS and future trends; examine impact of CPS on waste generation; and identify potential CPS to integrate waste minimisation strategies. The findings revealed that the most popular CPS in practice is design and build. Contractors believe CPS do have an impact on waste generation in construction. Specifically, integrated design and build and separated - cost reimbursable CPS have shown a significant impact on waste generation. Results also indicate that integrated CPS have major potential to integrate waste minimisation strategies than the management-oriented systems and separated systems. The content should be of interest to contractors, clients, and organisations dealing with procurement, waste and sustainability.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
