Dissatisfaction expressed by clients on the poor performance and level of service received from construction industry operators especially professionals gave birth to the need for this study. This study examined the measurement, valuation and payment for bills of quantities items consistently not executed by contractors in Nigeria. Primary data for this study was obtained from questionnaire randomly administered to Quantity Surveyors at a conference in 2008 and secondary data obtained from the elemental analysis of ten bills of quantities of bungalow buildings in Owerri. The substructure bill of ten projects was also analyzed and the mean item score and regression was calculated to show any relationship between the cost of unexecuted substructure items and the total cost of substructure.Elemental analysis reveal that substructure showed the slightest decrease of 16% in proportional cost allocation in 2010 compared to other elements of similar bungalow buildings using 2003 figures.The study also revealed that bill of quantities contain some measured items consistently not executed in practice by contractors in Nigeria, but which are eventually valued and paid for during interim valuation and final accounts,the items have significant implication on the cost of the project. With a calculated correlation coefficient of 0.99, it means that there is a very strong positive relationship between Total cost of unexecuted items and Total cost of substructure, also a calculated t-value of 19.545 with corresponding p-value as 0.000 shows that at 0.05% level there is a very strong positive correlation between cost of unexecuted items and cost of substructure which means that the cost of unexecuted items has significant effect on the total cost of substructure
