In Africa the number of required housing units is estimated at 4,000,000 units per year 60% of the demand being in the urban areas. In Kenya the total cost of stalled projects like affordable housing and roads is about 9 trillion. The purpose for this research was to seek the impact BIM could play in mitigation of these incomplete projects. The specific objectives of this research are to determine; the scale of usage of entire spectrum of BIM dimensions and its? influence in preventing cost and time overruns in Nairobi county. Questionnaires and oral interviews were used to collect data from 237 professionals in the built environment and 30 firms in AEC Nairobi County. The data from questionnaires was coded in SPSS and analyzed statistically while the oral interviews were analyzed thematically. The study found out that there was a statistically significant difference in both cost and time for projects done pre-BIM adoption compared to projects undertaken post-BIM adoption. The research also found that most AEC firms have only evolved to level 1BIM. More awareness needs to be created on the benefits BIM can offer as well as the need to employ knowledgeable professionals for its successful implementation. However, the benefits of employing the entire spectrum of BIM must be carefully considered against the size of projects.
