Both Standard Penetration Test (SPT) and Dynamic Cone Penetration Test (DCPT) have been carried out in Tanzania for many years whereby data obtained from these tests have been used for analysis and design of foundations. Data from various geotechnical investigation projects where the SPT and DCPT were carried out alongside one another were analysed and used to formulate correlations between the two tests data for different soil types while considering testing depth for each soil type. From the analysis, it was observed that a strong correlation between DCPT values and SPT values exist. These correlations can be useful in soil investigation works whereby the number of SPT testing involving expensive boreholes drilling can be reduced while supplementing them with DCPT thus enjoy time and cost saving ability of the DCPT at the same time obtaining more detailed information of the ground within the site being investigated.
