Abstract

Screw Driving Sounding (SDS) test has been developed in Japan as the improved version of the Swedish Weight Sounding (SWS) test. The development of SDS is to reduce the drawbacks of the SWS with the integration of rod friction estimation. Deep boring with Standard Penetration Tests (SPT) together with soil sampling for laboratory tests have been the common procedure for determining the subsurface soil profile and geotechnical engineering properties. However, the SPT which is associated with deep boring, uses high fossil fuels, needs high skilled workers and expensive. This paper presents the SDS technology and the SDS test results in comparison with the existing SPT data from six (6) selected sites in Malaysia. Results show that there is a strong correlation between SPT and SDS data, and the soil profile is better identified using SDS than the SPT. It is predicted that SDS test has the potential to replace conventional soil investigation methods, particularly in soft soils area. It is not just fast, cheap and does not require highly skilled workers but SDS tests supports green technology and sustainability in construction. Quality results are guaranteed from the usage of Industrial Revolution 4.0 technology through automation in testing and making use of the cloud computing to manage the data.

Abstract

Conventional soil investigation methods such as Mackintosh Probe Test (MPT) have limitations, e.g., require manual work for the equipment and data accuracy is low due to human error. While Standard Penetration test (SPT) needs high skilled workers and the cost per testing is expensive. Hence, Screw Driving Sounding test (SDS) was developed in Japan as a solution to the aforementioned disadvantages. An attempt was done to implement this test in Malaysia at different types of soils. This paper presents the results obtained from Batu Pahat and Cheras sites. Data from SDS tests were compared with the existing data of SPT and MPT available from Batu Pahat and Cheras sites, respectively. Results of the coefficient of determination, R2 = 0.721 for Batu Pahat Site and 0.851 for Cheras Site illustrate that the SPT and MPT results are highly correlated with SDS test results. From this preliminary findings, it shows that SDS test has the potential for soil characterizations in soil investigation work in Malaysia.
