Which of the following would be considered waste or rubbish at a construction site?

Unused construction materials are classified as waste or rubbish at a construction site because they are items that are no longer needed for the ongoing project and do not contribute to its completion. Proper waste management is essential on construction sites to maintain safety, compliance with regulations, and a tidy work environment. Unused materials can take up valuable space, create obstacles, and potentially create hazards if not disposed of correctly.

On the other hand, tools used for repairs are necessary for ongoing work and maintenance, measurements taken for planning are critical for executing construction projects accurately, and architectural models serve as important visual aids during the design and planning phases. Therefore, these items do not fit into the category of waste or rubbish, as they are essential to the construction process.
