Sanni, A A and Windapo, A O (2008) Evaluation of contractor’s quality control practices on construction sites in Nigeria. In: Dainty, A (ed.) Proceedings of 24th Annual ARCOM Conference, 1-3 September 2008, Cardiff, UK.
Abstract
Quality is linked to and affects many areas of human endeavour. This study evaluates the quality control practices on construction sites in Nigeria, by establishing if contractors have a quality control plan, the basis for the quality control plan and the manner in which the quality control plan is implemented on site. The study also identified the areas of difficulty experienced by contractors in the implementation of their quality control plan on the construction site. Relevant literature on quality systems and standards in use that highlights what a quality control plan should contain was reviewed, based on which a 20-point contractor evaluation questionnaire was developed. A total of 46 recently completed building projects were examined and analysed. Using the statistical data obtained and analysed with the use of descriptive and inferential statistics including Pearson product moment correlation test, the survey carried out indicates that most contractors in Nigeria; especially in Lagos possess quality control plans and for which a good level of compliance on site was reported by respondents. The research findings also indicated that there is a significant relationship between the implementation of a quality control plan and delivering a high quality project; where there were no quality control plans the quality of the delivered project was adjudged low. It was concluded that without adequate quality control plans and effective implementation on construction sites the Contractor would not achieve a significant quality delivery. The study recommends that project managers and other team members should view the possession of an effective quality control plan as essential in pre-selecting contractors, and its implementation on site as essential to improving the quality of projects delivered in the 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
