Abstract
A survey, involving 51 respondents, was conducted to compare the effects of traditional contract procurement and the contemporary direct labour system on two client objectives within the Nigerian context, namely project cost and time. Fixty-six building projects were also studied of which 35 were executed by traditional procurement and 21 by direct labour. Mean cost overruns and mean time overruns were used as basis for the comparisons. Statistical analysis was utilised in effecting the comparisons, which showed the mean cost and time overrun for traditionally procured projects to be 53.5% and 160% respectively. For the direct labour system, the comparative values were 24% and 27% respectively. Although the direct labour system performed significantly better than traditional procurement, it still involved overruns and hence, it is not a perfect solution to project implementation problems in the Nigerian construction industry

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
