Modular construction is redefining the way plants are built. This approach goes beyond assembling prefabricated modules; it involves precision engineering and standardization. Modules are constructed off-site, benefiting from controlled environments and skilled labor. A closer examination reveals that modular construction significantly reduces construction timelines. Modules can be fabricated concurrently with on-site work, and quality control is enhanced due to factory-standard production. The result is fewer defects, reduced rework, and minimal delays. With its advantages of cost-effectiveness and improved quality, modular construction is emerging as the preferred method for complex plant projects.
