Frimpong, Y and Oluwoye, J (2003) Significant factors causing delay and cost overruns in construction of groundwater projects in Ghana. Journal of Construction Research, 4(2), pp. 175-187. ISSN 1609-9451
Abstract
In groundwater construction projects, many variables affect construction schedule and cost overruns. This paper aims to examine and evaluate the relative importance of the main factors that cause delay and cost overruns in groundwater construction projects. In order to identify these factors, a questionnaire survey was conducted. Questionnaires were sent to professionals involved in groundwater construction projects in Ghana. The data was analyzed and ranked, based on the profession of the respondents and their roles in the industry (i.e. owners, contractors and consultants). The questionnaire survey consisted of 49 factors which were grouped into nine major categories, and the level of importance of the categories was measured and ranked by the relative importance weights. The percentage agreements in ranking among the three groups were measured. The results shows that: (1) the surveyed groups generally agreed that the project financing category is the main reason for groundwater construction delay and cost overruns, whereas the labor category is the least; (2) owners, consultants and contractors substantially agree on the ranking of the major categories of delay and cost overruns factors. The paper concludes that all the three groups felt that project financing, micro-economics, natural conditions and materials factor categories play a predominant role in causing delay and cost overruns to groundwater construction projects.

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
