Answer:
False. Shoring tables are used to determine the appropriate shoring system to be used during excavation or trenching operations based on the soil type and other site-specific conditions. The tables are typically developed based on the results of soil testing and analysis and provide guidelines for selecting the appropriate shoring system based on the soil type, excavation depth, and other factors. Therefore, it is important to determine the soil type before using shoring tables to ensure that the appropriate shoring system is selected to provide adequate support and prevent soil collapse or other excavation-related hazards.
