Engineer: "Hey ChatGPT, what is the minimum required compressive strength for concrete in building foundations?"
ChatGPT: "The minimum required compressive strength for concrete in building foundations varies depending on the building code and design requirements. However, a common requirement is a compressive strength of 2500 psi after 28 days of curing. The engineer should also consider other factors such as the site conditions, loading requirements, and durability requirements when designing the foundation."
