Amazon Cuts Data Centre Construction Time From Months to Weeks With Factory-Built Modules
Amazon Web Services is testing a new construction method that could reduce data centre build times to two or three weeks, down from the current 15 weeks. The initiative, called Project Houdini, shifts most assembly work from job sites to factories, where prefabricated modules arrive ready for installation.
The company expects the system to be operational by August and plans to use it for more than 100 data centres annually.
How the modular approach works
Instead of traditional on-site construction, AWS will use prefabricated "skids"-complete units that include server racks, power systems, cabling, lighting, and security features. These modules are built in controlled factory settings before transport to data centre sites.
The shift eliminates roughly 50,000 electrician hours per data hall, according to internal documents reviewed by Business Insider. Currently, constructing a single data hall requires 60,000 to 80,000 labour hours total.
AWS is developing the system with partners including Cupertino Electric Inc., with initial production planned in Topeka, Kansas; Houston; and Salt Lake City.
Why speed matters now
AWS faces persistent capacity constraints as demand for AI infrastructure outpaces supply. Chief executive Andy Jassy noted in a recent shareholder letter that demand still exceeds available capacity.
Modular data centres are not new-companies like Schneider Electric and Vertiv already sell prefabricated systems. What distinguishes Amazon's approach is the scale and scope: the company is applying modular construction to larger portions of hyperscale facilities, including core server environments.
Shaolei Ren, an associate professor at the University of California, Riverside, said the integration level and inclusion of AI servers at this scale represents an evolution of existing modular design.
Power remains the real bottleneck
Faster construction does not solve the industry's primary constraint: securing power supply and grid connections. These negotiations can take years-far longer than building a data centre.
Dimitrios Nikolopoulos, a professor at Virginia Tech, said accelerating the build process to weeks has limited impact if grid power connections face years-long delays.
This reality has pushed cloud providers toward alternative strategies, including on-site power generation and nuclear energy investments.
Once power infrastructure is secured, however, construction speed becomes critical. Project Houdini represents AWS's effort to compress that phase and respond faster to rising AI demand.
For construction and real estate professionals, this shift signals a broader industry move toward factory-based assembly and modular approaches. Learn more about AI for Real Estate & Construction and AI for Operations to understand how these changes affect project planning and delivery.
