A modular building project generally consists of several major stages, each contributing to the overall delivery schedule.
Architectural, structural, and MEP designs are developed and reviewed before manufacturing begins.
Modules are fabricated, assembled, and partially fitted out in a controlled factory environment.
While factory production is underway, foundation work and site infrastructure can often proceed simultaneously.
Completed modules are delivered to the project site, lifted into position, and connected according to the installation plan.
Mechanical, electrical, plumbing, and other building systems are tested before the project is handed over.
Not necessarily. While parallel factory production and site preparation can improve efficiency, the overall project schedule depends on design, approvals, manufacturing capacity, logistics, installation, and site conditions.
The duration varies by project. Engineering design, factory production, transportation, and regulatory approvals can all significantly influence the final schedule.
International buyers commonly review engineering lead times, manufacturing schedules, production capacity, logistics planning, installation sequencing, commissioning procedures, and the supplier's ability to meet agreed delivery milestones.
Clear project requirements, timely design approvals, coordinated manufacturing, effective logistics planning, and close communication among project stakeholders can help improve schedule performance.
