Factory Integration vs Field Integration

Modular data center construction can follow different integration strategies — some systems fully assembled and tested in a factory before shipping, others built to a modular specification but integrated on site. Understanding the difference helps clarify what a modular program is actually buying, and where responsibility sits between supplier and site team.

What Factory Integration Covers

Factory integration means major systems — electrical, mechanical, sometimes both — are assembled, wired, and functionally tested inside modules before they leave the factory, so a larger share of the work happens in a controlled environment ahead of delivery. This can reduce the amount of on-site assembly work required, though the modules still need to be set on foundations, connected to site utilities, and commissioned once delivered.

What Field Integration Covers

Field integration means individual modules or components — a switchgear building, a cooling module, an electrical building — are delivered separately and connected to each other and to site infrastructure after arrival. This approach can offer more flexibility in sequencing and site layout, at the cost of more on-site integration work compared with a fully factory-integrated system. Integrated modular data centers and multi-building data center infrastructure reflect these two ends of the spectrum.

Delivery and Responsibility

Data Center Modular manufactures modules built to either integration approach, depending on what a given project's design calls for. Final on-site integration, utility connections, commissioning, and inspections remain the responsibility of the project's own engineering team and local contractors in every case, regardless of how much integration work was completed in the factory.
