When a hyperscale data center breaks ground in a new market, the contract stack beneath that project is often as complex as the building itself. Buried inside those documents, almost without exception, is a non-disclosure agreement. Most people assume NDAs are about protecting trade secrets, and they are, but in construction they do something more specific, and more consequential, than that simple description suggests.
What NDAs Actually Cover in a Construction Context
A non-disclosure agreement in construction typically restricts what contractors, subcontractors, suppliers, and consultants can say about a project, once it is complete as well as while it is underway. That can include the identity of the end client, the building’s intended use, the technologies being installed, the cost breakdown, the timeline, and the design specifications.
For data center projects, the sensitivity runs especially deep. A hyperscaler building a new facility does not want competitors to know the location, the power capacity, the cooling strategy, or the specific hardware configurations planned for the space. The NDA is the legal mechanism that keeps that information inside the project team.
Beyond protecting competitive intelligence, NDAs in construction serve another function: they limit the public record that workers, contractors, and vendors can contribute to. A subcontractor who has waterproofed a dozen data center foundations has valuable knowledge about how those buildings perform over time. Under a standard NDA, sharing that knowledge, even in a general professional context, can carry legal risk.
The Cost of Confidentiality
The construction industry has long relied on shared knowledge to improve safety, reduce errors, and drive down costs. When large portions of the market operate under blanket confidentiality, that knowledge transfer slows down. Research in adjacent fields suggests that information silos contribute to repeated mistakes and inefficiencies, though quantifying the precise effect in construction is difficult because, by definition, restricted information does not circulate.
There is also a public interest argument. Data centers now consume a significant share of electricity in many regional grids. As of 2024, some utility commissions and state regulators were beginning to ask harder questions about the infrastructure footprint of large technology campuses, including water use and grid impact. When construction contracts restrict disclosure of basic project parameters, it can complicate that regulatory oversight.
Labor advocates have raised a separate concern. Workers injured on confidential projects sometimes face pressure, explicit or implicit, not to discuss the circumstances of their injury in ways that might identify the project or the client. Legal experts in construction law have noted that NDAs cannot lawfully override mandatory incident reporting requirements in most jurisdictions, but the chilling effect on informal disclosure is harder to measure.
Why Waiving an NDA Matters
When a project owner or developer voluntarily waives NDA requirements, even partially, it changes the landscape in practical ways. Contractors can publish case studies. Architects can enter their work for industry recognition. Suppliers can cite the project in technical documentation. Workers can speak more freely about what they built and what they learned.
For the data center sector specifically, the clearest recent moves have been aimed at public officials rather than trades: Microsoft said in March 2026 that it would end its existing NDAs with local governments, and Amazon said in October 2026 that it would stop using NDAs with government agencies on data center projects, going forward only. Whether similar relief reaches contractors is less clear, though the logic would be straightforward: the best subcontractors have options, and the ability to claim credit for a high-profile project is a meaningful recruiting and business development tool.
Transparency waivers also matter for the communities hosting these facilities. A municipality that approves a large industrial construction permit has a legitimate interest in knowing, at some point, what was built and how it operates. Full commercial confidentiality can put local governments in the awkward position of having approved something they cannot fully describe to their own constituents.
Where This Goes from Here
The tension between legitimate confidentiality and the broader value of open information is not going to resolve itself cleanly. Project owners have real reasons to protect competitive information, and those reasons do not disappear because transparency has social benefits.
What is shifting is the negotiating dynamic. As data center construction has accelerated across North America, Europe, and parts of Asia, the contractors and trades with specialized experience have gained leverage. That leverage is increasingly being used, in some cases, to push back on the most sweeping NDA terms. Whether that trend continues will depend partly on how tight the labor and contractor market remains, and partly on whether regulators decide that public infrastructure deserves a more public record.
