What does construction technology refer to?

Construction technology encompasses the knowledge, tools, and methods used to create and construct buildings and other structures. This broad field includes understanding materials, processes, and modern innovations that contribute to the building industry. The focus is not only on the physical act of building but also on the application of scientific and engineering principles to ensure structures are safe, sustainable, and efficient.

In contrast, other options describe more limited aspects of the construction process. While techniques for demolition are a part of construction, they do not encompass the entirety of construction technology. Similarly, technology for planning pertains specifically to the pre-construction phase, which is only one component of the broader field. Finally, repair technologies are relevant but also represent a narrow focus within the larger context of constructing new structures or systems. Thus, the broad and inclusive nature of the answer is what makes it the correct choice.
