Geotechnical investigations are progressing across the proposed site to plan for the new port and supporting infrastructure in Kwinana. These investigations are the first major step in any infrastructure project, taking and analyzing samples to create a record of the subsurface conditions which will inform the design and construction of the port. Westport Project Manager, Roger Goga , said: “So far, the geotechnical investigations have confirmed our initial studies of the area, with the process also about collecting further details.” “We have found limestone beneath the surface which is what we thought we would find, but it’s the details of the limestone that we’re trying to determine, such as how strong it is, and what depth it’s encountered at.”
