Theoretical concept was validated via a processual lens of a systematic literature review with cost variability and construction projects as search string within three databases: Scopus, Web of science and EBSCO (BSP) (Business source premium), which were further studied and knowledge or research gaps identified. The review indicated factors causing deviation between final accounts and contract sum varied from 1 to 45, thus meeting objective 1 of the study. Data collection will be achieved using interviews and questionnaires to consider other objectives of peculiarities, severity, effects and ways of mitigating risk, leading to the development of a cost estimating framework that is adjudged an essential tool in risk shedding rather than risk-sharing in project risk management, which would be a solution to cost estimation problems, leading to cost variability in the Nigerian construction industry.
