Which of the following is not an example of technology used in construction?

Telephones are primarily communication tools and do not directly relate to the construction process itself. While they facilitate communication between teams and clients, they do not contribute to construction activities or enhance methodologies within the field.

In contrast, the other options represent advancements in technology that have a direct impact on construction. Robots can perform tasks such as bricklaying or demolition, enhancing efficiency and safety. Simulators can provide training for workers, allowing them to practice skills in a virtual environment without the risks associated with actual construction sites. Drones are increasingly used for site surveys, providing aerial views of construction projects, improving project planning, and monitoring progress.

Therefore, in the context of the construction industry, telephones stand apart as a traditional communication method rather than a technological advancement that influences construction practices.
