What are the two types of enduring construction mentioned?

The two types of enduring construction referenced are semi-permanent and permanent. Semi-permanent structures are designed to last for an extended period but are not intended for indefinite use. They often incorporate materials and designs that allow for some level of adaptability or eventual disassembly. Permanent construction, on the other hand, refers to buildings or structures that are intended to remain in place for a very long time, featuring durable materials and construction techniques that provide stability and longevity.

Understanding these distinctions is crucial in the context of urban planning, architecture, and construction, as they determine the type of materials used, the design approach, and the lifecycle of the structure. This classification helps professionals in making informed decisions about the types of projects they undertake, considering factors such as economic sustainability, environmental impact, and community needs.
