A typical module length in Singapore ranges from 6 meters for MEP modules to up to 12 meters for modular building units, depending on transport and site constraints.

Prefabricated MEP Modules

For mechanical, electrical, and plumbing (MEP) prefabricated modules, the standard length is usually 6 meters, with widths varying according to the services included. These modules are fully assembled in the factory, including control panels, pumps, valves, and cable terminations, and are designed to comply with Singapore regulatory requirements and SCDF codes. The modules are equipped with lifting lugs for hoisting and installation, and firestops can be integrated for better quality and productivity .

Modular Building Construction

In modular building construction, the length of modules is influenced by transportation limits, site access, and structural stability. Typically, modules can be designed up to 12 meters in length, which is considered practical for most construction sites in Singapore. Longer modules may require additional bracing or special transport arrangements. The framework often uses steel C-sections or hollow sections, and modules can be placed side by side to create larger open-plan spaces, such as in hospitals or schools .

Considerations for Choosing Module Length

• Transport and site access: Narrow streets or tight urban sites may limit module length.
• Structural stability: Longer modules may need additional bracing or reinforcement.
• Integration with services: MEP modules must accommodate risers, ducts, and electrical services efficiently.
• Regulatory compliance: Modules must meet local building codes, fire safety, and SCDF requirements.

In summary, for Singapore, 6 meters is typical for MEP modules, while up to 12 meters is practical for general modular building units, balancing ease of transport, installation, and compliance with local standards .
