For which testing method is boring typically not necessary?

• A. A) Sample collection
• B. B) In situ testing
• C. C) Visual inspection
• D. D) Water table assessment

Answer: (C)

Visual inspection is a testing method that does not require boring because it involves examining the site and its features directly without the need for subsurface access or the collection of soil samples. Visual inspections are conducted to assess surface conditions, identify visible signs of distress or erosion, and evaluate existing structures or pavement without disturbing the ground. This method relies on the observer's ability to gather information through sight, making it a non-invasive approach. In contrast, methods such as sample collection and in situ testing typically involve boring to obtain soil or rock samples or to perform tests within the soil. These methods require access to subsurface materials, which necessitates boring to reach the depths needed for analysis. Water table assessment often requires boring as well, particularly to measure the water level at certain depths. Therefore, visual inspection stands out as a method where boring is unnecessary.
