Abstract

Road construction is an important activity which emits a huge amount of greenhouse gases. Voluntary actions to reduce the emissions from construction practices have rarely received attention from contractors because eco-construction methods tend to incur extra project costs and induce the bidders' concern to lose the bidding competitions. This study developed an incentive procurement system named Green Road Incentive Procurement (GRIP) to persuade contractors to adopt environmental-friendly construction methods. Initially, GRIP proposed six highly potential alternative construction methods of emission reduction for which bidders could choose as their preference. To ensure the acceptance and collaboration of this new GRIP, a survey study was conducted on two directly involved parties of road construction projects, contractors and public owners, which were selected as a sample group. The Analytical Hierarchy Process (AHP) was used to evaluate an opinion by three options based on eight criteria. The results showed that both contractors and the public owners gave the highest weighted scores for the GRIP full implementation alternative. The users' readiness was an AHP criterion, which both parties were mutually concerned as the highest significance. These results confirmed that both involved parties agreed with the concept of GRIP and were pleased to cooperate with the GRIP implementation.

Descriptive scope: 4 PCEA

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
