Prefab Construction: A Growing Trend

Prefab construction, often referred to as off-site construction, is the process of fabricating building or structure components in controlled factory environment prior transporting & assembling them on-site. This strategy contrasts sharply with the traditional on-site construction method, which depends primarily on physical labour, resulting in frequent delays, price hikes, and variable quality. Traditional on-site construction, as a common method, has been criticized because of its inherent drawbacks, such as long construction time, low productivity, external weather constraints, waste of resource, environmental pollution, poor safety, etc.

In recent years, the construction industry has witnessed a significant shift towards prefabrication as a method of construction. Prefabrication has various terms such as industrialized construction, prefabricated construction, modular construction, and off-site construction. The key characteristics of prefabricated construction is standardization of architectural designs, industrialization of component production, mechanization of construction, and scientific organization and management.

Prefabricated construction, introduced as a major mode for promoting environment and sustainability performance in the construction industry, offers numerous advantages over traditional on-site construction methods, including cost saving, enhanced efficiency, improved quality control, reduced construction timelines, and increased safety. As a result, prefabrication has gained immense popularity and is becoming increasingly important in the construction industry.

Reduces Construction Timelines

Prefabricated construction significantly reduces construction timelines by enabling simultaneous site preparation and off-site fabrication. The controlled factory environment allows for streamlined processes, precise assembly, and faster completion, leading to reduced construction time.

With off-site manufacturing, construction activities on-site and component manufacturing can occur simultaneously. This parallelism reduces overall construction timelines and allows for faster project completion. Since prefabricated components are manufactured in a controlled environment and delivered to the site ready for installation, on-site assembly requires less time than traditional construction, as components can be quickly connected or assembled, resulting in shorter construction timelines. Prefabrication also simplifies construction coordination by reducing on-site dependencies; with standardized components and clear assembly instructions, coordination challenges and delays associated with multiple trades working simultaneously are minimized.

When it comes to reducing time, prefabrication processes can make a difference. For example, construction professionals have estimated that a prefabrication approach can save up to 50% or more in schedule savings on commercial and industrial projects.
