Praticò, F G (2007) Quality and timeliness in highway construction contracts: A new acceptance model based on both mechanical and surface performance of flexible pavements. Construction Management and Economics, 25(3), pp. 305-313. ISSN 1466433X
Abstract
Timely completion and high performance are becoming key factors in modern road projects, so research is needed to have reliable contracts and acceptance criteria. The goal of this paper is confined to the formalization and validation of a unique model for the determination of pay adjustment on the basis of both quality (mechanical and surface performance of road pavements) and timeliness. Three main topics are addressed. The first is the estimation of pay adjustment (PA, negative or positive) when both structural and non-structural deficiencies/ surplus in characteristics are detected (e.g. low drainability in porous asphalt concretes). The second is the estimation of PA based on the quality of all the layers of the pavement. The third is the estimation of PA for early or late completion of the work. The formalized model is applied to an experimental case history. Analyses and validation demonstrate that the proposed model can efficiently solve typical problems in contract administration, in which decisions based upon objective criteria are needed.

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
