Abstract
Various factors identified from the literature that caninfluence quality of building projects in Nigeria have beenstudied by means of questionnaire survey sent to architects,engineers and quantity surveyors in the industry. From atotal response of 107 consultants, the importance of eachfactor was obtained via severity and frequency responsesof the factors. Data analysis includes comparisons ofranking among consultants using severity, frequency andimportance indexes, correlation analysis, and percentagerank agreement factor (PRAF) to measure the agreement inthe importance ranking among the consultants.Correlation results between the professionals are architects/quantity surveyors (0.75), architects/engineers (0.21 ),and engineers/quantity surveyors (0.24). The percentagerank agreement factor (PRAF) shows that the five mostimportant factors affecting quality are 'design changes'(78.9%); 'inadequate involvement of other professionalsduring the design stage' (78.9%); 'insufficient andunrealistic constraints of project cost' (71.1 %); 'poor levelof commitment to quality improvement among designprofessionals' (63.2%); and 'making design decisions oncost and not value of work' (55.3%). The results of this studywould provide feedback for the clients, project and qualitymangers and all the consultants in the industry, so thateffective management of quality can be ensured from theconceptual-design stage of the project.

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
