Final answer:
In new construction, a curb can be assembled and installed after the formwork support system is established. This system acts as a mold for materials like concrete to form the curb.
Step-by-step explanation:
If the curb is mounted as part of a new construction process, it can be assembled and installed as soon as the formwork support system is in place. The formwork serves as a mold for the concrete or other materials used to create the curb, ensuring it has an accurate size, shape, and finish. After the formwork is securely in place and has been properly inspected for stability and precision, the construction team can proceed with pouring the concrete into the formwork to shape the curb.
