Advantages:
1. Speed: Prefabricated or modular construction techniques can be completed faster than traditional construction techniques as the modules can be pre-made in factories before being transported to the construction site for assembly.
2. Cost: Modular construction is often cheaper than traditional construction because it’s simpler and faster. The use of standardized modules reduces the need for on-site labor and reduces waste.
3. Quality control: Prefabricated and modular construction techniques make it easier to achieve consistent quality as all modules are built to specific specifications in controlled factory conditions.
4. Flexibility: Modular construction is flexible and adaptable to different needs. It allows for the easy addition or removal of modules to respond to changing requirements, making it ideal for temporary buildings such as schools and hospitals.
Disadvantages:
1. Limited customization: Prefabricated and modular construction techniques allow less flexibility in design and room for customization, as they are based on standard modules.
2. Transportation limitations: The size of the modules may be limited by transportation restrictions such as height and width limits, which can limit the design and functionality of the building.
3. Potential for damage during transportation: While modules are built to withstand transportation, there is still a risk of damage during transportation to the site, which may lead to additional costs for repairs.
4. Limited site access: Some sites may not be suitable for modular construction, such as sites with limited access or space, which may increase the complexity and cost of the project.
5. Permits and zoning: Modular construction requires permits and zoning approvals, just like traditional construction, which can be time-consuming and could delay construction.
