Abstract: The study determined the extent of occurrence and assessed the impact of project risk factors on the choice of national competitive tendering (NCT), the dominant of the six (6) procurement methods used by public entities, in the procurement of works in Ghana. Data for study were collected by means of a questionnaire survey and analysed statistically through the comparisons of means using one-way analysis of variance. Twenty six (26) project risk factors were evaluated and ranked. Financial and design risk factors were found to have the highest impact on works procured through NCT. A public works risk impact matrix revealed that, financial and design risks factors have the high extent-high impact on projects procured through NCT. Economic related risk factors have low extent-high impact of occurrence. Environmental and construction related risks have low extent-low impact on the risk matrix.
