5short Q&A pairs drawn directly from our worked dot-point answer. For full context and worked exam questions, read the parent dot-point page.
What is the factors geologists check?Show answer
A ground assessment looks at several linked factors:
What is the site investigation?Show answer
Because these problems are hidden underground, a site investigation is carried out before construction. It typically uses boreholes to sample the rock and soil at depth, find the water table and the depth to sound rock (rockhead), and test the ground's strength and permeability, together with geological maps and cross-sections of the area. The results let engineers design suitable foundations, choose a safe route or site, or move the project if the ground is too poor.
