Choosing a plot of land is the easy part of building a data centre. The real investment decision hinges on power availability, permitting timelines, and cooling technology, factors that experienced construction consultants, including Mitchell McDermott, are typically asked to assess before a single pound is committed. As demand for digital infrastructure keeps climbing, businesses that treat site selection as a formality rather than a full feasibility exercise tend to discover expensive surprises later in the process.
Power Comes Before Everything Else
A data centre without a secure, scalable power connection is not a viable asset, regardless of how attractive the site looks on paper. Grid connection studies should happen at the very start of a feasibility process, not after land has already been optioned. Investors increasingly ask about power purchase agreements and renewable supply arrangements as part of due diligence, since energy cost and availability now shape a facility’s long-term economics as much as construction cost does. A site with abundant land but a constrained grid connection can quietly become the most expensive option once the true cost of securing extra capacity is factored into the plan.
Permitting Timelines Can Make or Break a Business Case
Planning approval for large-scale digital infrastructure can take considerably longer than for a typical commercial building, particularly where local grid capacity or water use raises questions from planning authorities. Businesses that build a realistic permitting timeline into their financial model, rather than assuming a best-case scenario, avoid the painful situation of committed capital sitting idle while approvals work through the system. Engaging local authorities early and addressing community concerns directly often shortens the overall approval process more than any amount of paperwork submitted after objections have already formed.
Cooling Technology Is Now a Capital Decision
The rise of high-density computing for artificial intelligence workloads has pushed cooling from a technical afterthought into a core design decision. Direct-to-chip liquid cooling and other next-generation approaches can significantly reduce long-term operating costs, but they also change the building services specification and the upfront capital required. Getting this decision wrong late in the design process is far costlier than addressing it during initial feasibility work, since retrofitting a cooling system after construction has started can mean reworking large sections of the mechanical design.
Owner Furnished Equipment Adds Coordination Risk
Large technology clients frequently supply their own specialist equipment rather than leaving it to the main contractor, an approach known as owner-furnished, contractor-installed procurement. This arrangement can reduce cost, but it introduces coordination challenges across multiple supply chains and delivery schedules. Projects that manage this well tend to have a single point of accountability that tracks every piece of owner-supplied equipment against the wider construction programme, catching delivery delays weeks before they would otherwise stall the on-site installation sequence.
Benchmark Cost Against Comparable Global Projects
Because so few organisations build data centres regularly, internal cost benchmarks are often out of date or don’t exist. Comparing a proposed project against recent builds of similar scale in a similar region gives investors a far more reliable gut check than relying on a single contractor quote. This step alone catches a surprising number of budgeting errors before they become contractual disputes, and it gives an investment committee a defensible reference point when questions arise later in the approval process.
Making the Investment Decision With Confidence
Data centre development sits at the meeting point of construction, energy policy, and technology strategy, which is why most serious investors bring in specialist project management and cost advisory support before committing capital. Businesses that get this right treat the feasibility stage as seriously as construction itself, and it shows in how few surprises they encounter from building through commissioning to the eventual handover of a fully operational facility.
Commissioning Determines When Revenue Actually Starts
Even a well-built data centre generates no return until it passes commissioning and testing, a phase frequently underestimated in early project schedules. Power systems, cooling loops, and redundancy arrangements must be proven under load before a facility can accept live equipment, and rushing this stage to hit an announced opening date often creates reliability problems that surface only after tenants have moved in. Building a realistic commissioning window into the programme from the outset protects both the delivery date and the facility’s reputation once it is operational, and it gives investors a clearer sense of when the asset will begin generating income rather than simply absorbing more capital.
