Causes of Errors in Construction Contract Documents in Southwestern, Nigeria
AbstractThe issue of continual poor project performance in the construction industry remains unresolved and there is need for improvement. In view of improving project performance, the study aims at investigating the frequent causes of errors in construction contract documents. The survey research design and mixed research methods were used for the study. The respondents for the study consist of 86 consulting and 98 contracting firms that have been engaged on building projects that is above one floor between 2012 and 2015. Fifty one (51) interviews were also conducted on contractors, project managers and consultants on the projects they were involved and can equally provide necessary information for the study. Statistical Package for Social Sciences (SPSS 20) was used for the analysis of the study. The study found that the frequent causes of the errors in contract documents are frequent design changes by clients, lack of adequate time to prepare documents and design management experience among others. Based on the findings, it was concluded that the causes of errors in contract documents vary from one state to the other. It was also concluded that there is difference in the causes of errors in contract documents based on types of building, services rendered by construction organisations and states in South West, Nigeria. However, there is no significant difference in the causes of errors in contract documents based on procurement method except where there is incomplete documentation or contracting organisations have overlapping activities. The study recommends that the frequent errors identified should always be prevented from occurring if cost and time overrun are to be minimized. Also since most of the causes identified are related to consultants, it was recommended as suggested by interviewees that all designs must go through quality assurance process.
