Abstract
In building construction, discrepancies frequently occur between design and construction in relation to architectural details, structural details, materials, and quality of construction. The objective of this paper is to identify the major causes of discrepancies in building construction. A questionnaire was utilised that contained 65 potential causes of discrepancies classified into 4 categories: design, tendering, construction, and overall project. The data was from Pakistan and the response rate was excellent (80.6%). The collected data was analysed and important causes of discrepancies were identified. The results indicate that the provision of incomplete data to designers, lack of interest by approving authorities to carefully check the design, and owner-proposed changes due to financial problems are the top three causes of discrepancies. Insights and discussion are included in the paper. This work provides a basis to minimise discrepancies in the construction industry and help reduce rework, delays, and defects in construction.

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
