When Geopolitics Meets Concrete and Steel
The global datacenter industry has been on a breakneck expansion spree for years. Cloud services, streaming platforms, and artificial intelligence workloads demand ever more server halls. But a new and powerful force has entered the equation: the ongoing conflict involving Iran. This war is not just a headline on the news; it is a tangible problem for anyone trying to build a new datacenter. The closure of the Strait of Hormuz, a narrow waterway through which about a fifth of the world’s oil supply flows, has sent shockwaves through construction supply chains. The resulting impact on the iran war datacenter cost is profound, creating a perfect storm of rising prices, material shortages, and project delays. For project managers, procurement officers, and CFOs, this is a crisis that demands immediate attention and strategic thinking.
To understand the full scope of the problem, we need to break down the five most costly impacts of this conflict on datacenter construction. Each one represents a significant financial and logistical hurdle that the industry must navigate.
Impact 1: The 20 Percent Material Cost Spike
The most immediate and painful consequence of the Iran war is the dramatic increase in the price of essential building materials. Industry experts at BCS Consultancy report that construction firms are facing cost increases of up to 20 percent for certain materials. This is not a minor adjustment; it is a budget-busting surge that eats into already tight profit margins.
Why Oil Prices Matter for Concrete and Steel
The connection might not be obvious at first. Why would a conflict in the Middle East make steel more expensive? The answer lies in energy. Producing materials like steel, aluminum, and cement is incredibly energy-intensive. Modern steelmaking, for example, relies heavily on electric arc furnaces or blast furnaces that consume vast amounts of energy. Cement production requires heating kilns to over 1,400 degrees Celsius, a process that traditionally uses fossil fuels. When the Strait of Hormuz closes, global oil prices spike. This directly increases the cost of manufacturing these critical construction inputs.
Oskar Lampe, regional director at BCS Consultancy, puts it plainly: “For datacenter construction, the key components of which consist of exactly these materials, this is a turning point.” A CFO at a construction firm who had budgeted for a new facility six months ago might now find that their steel and cement line items have ballooned by nearly a quarter. This leaves them with a painful choice: absorb the loss, pass the cost to the client, or halt the project. None of these options are ideal in a competitive market where speed to market is critical.
A Hypothetical Scenario: The Budget Meeting
Imagine you are the CFO of a mid-sized construction firm specializing in colocation datacenters. You have just won a contract to build a 10-megawatt facility. Your initial budget assumed a steel cost of $800 per ton. Now, due to the conflict, that same ton of steel costs $960. For a project requiring 5,000 tons of steel, that is an unplanned $800,000 expense. This is the harsh reality of the iran war datacenter cost reality playing out in real time. It forces difficult conversations about renegotiating contracts, seeking additional financing, or accepting a lower profit margin.
Impact 2: Delivery Volumes Slashed to a Quarter
Price hikes are bad enough, but they are compounded by a second, equally damaging problem: availability. The supply of certain materials has been severely curtailed. In some cases, the quantity available for delivery has been reduced to just a quarter of the required amount. This means that even if a construction firm is willing to pay the higher price, they simply cannot get enough material to proceed with their build.
The Fragility of Just-in-Time Supply Chains
The datacenter construction industry, like many others, has long relied on just-in-time supply chains. Materials arrive at the construction site exactly when they are needed, minimizing storage costs and keeping projects lean. This system works well in a stable world. But a geopolitical shock like the Iran war exposes its fragility. When a key supplier in the Middle East cannot ship because the Strait is closed, or when a domestic producer cannot get the energy needed to run their factory, the entire pipeline dries up.
Andrew Buss, senior research director at IDC, notes that this vulnerability predates the current conflict. “We’re hearing some reports of broader supply chain disruption and availability issues – particularly for things like high-voltage transformers and copper supply – around datacenter builds from even before the war in the Middle East and the resulting closure of the Straits of Hormuz. So the closing of the Straits is certainly not helping, but this has been an issue for some time.” The pre-existing fragility has now been magnified, creating a disproportionate impact. A procurement officer who used to order steel from three suppliers might now find that two of them have zero stock available for new orders. The third supplier can only offer a fraction of the needed volume, at a premium price.
Concrete Delays: A Real-World Example
Consider the challenge of securing cement. Cement is heavy and expensive to transport over long distances, so it is typically sourced locally or regionally. But local cement plants depend on energy. If a domestic plant uses natural gas or oil to fire its kilns, and the price of that fuel doubles due to the Strait closure, the plant may reduce its output or shut down temporarily. This creates a local shortage. A datacenter project in Europe or Asia that was counting on a steady supply of cement from a nearby plant might suddenly find itself with only a quarter of the required tonnage arriving each week. The project manager then faces a grim choice: slow the pace of construction (which increases labor costs and extends the timeline) or scramble to find alternative sources, which are likely more expensive and farther away.
Impact 3: Critical Plant Equipment Delays of 5 to 38 Months
Beyond raw materials like steel and cement, datacenter construction relies on highly specialized plant equipment. This includes items like chillers, transformers, generators, and switchgear. These are not off-the-shelf products; they are often custom-engineered for a specific facility. Their lead times are already long under normal conditions. The Iran war has made a bad situation much worse.
Understanding the Lead Time Spectrum
Oskar Lampe points out that delivery times for this critical equipment can vary from 5 to 38 months. That is a staggering range. A 5-month lead time is manageable for a well-planned project. A 38-month lead time is a project killer. The war has pushed lead times toward the upper end of that spectrum for several reasons. First, the manufacturers of this equipment often rely on a global supply chain for their own components. A transformer, for example, might require copper windings, steel cores, and specialized insulating materials. If any of those inputs are disrupted by the conflict, the entire production line slows down. Second, the general economic uncertainty caused by the war leads to a surge in orders as companies try to secure their place in the queue, further straining manufacturing capacity.
Lampe advises that “those who only start the procurement process when the project plan dictates will order at a higher price and wait longer.” This is a critical lesson for project managers. In the current climate, waiting is a luxury that few can afford. A delay of even a few months in placing an order for a generator can result in a multi-year wait, effectively freezing the entire project timeline.
Practical Action: The Early Ordering Mandate
The solution, while simple in concept, requires discipline and foresight. Project teams must identify all long-lead items at the very beginning of the planning phase, even before ground is broken. These orders should be placed immediately, with the understanding that the final specifications might need to be locked in early. This carries some risk—if the design changes later, the equipment might not fit—but the risk of not ordering is far greater. Building price escalation clauses into contracts with suppliers can also help. These clauses allow the price to adjust based on documented increases in raw material costs, protecting both the buyer and the seller from extreme market volatility.
Impact 4: The Compounding Effect of Pre-Existing Challenges
The impacts of the Iran war do not exist in a vacuum. They land on top of a set of pre-existing challenges that were already making datacenter construction difficult and expensive. This compounding effect means that the iran war datacenter cost is not just about the war itself; it is about how the war amplifies every other problem.

Land, Planning, and Grid Connection Woes
Before the war, datacenter developers were already struggling with three major hurdles: finding suitable land, securing planning permission, and getting a grid connection for power. Suitable land is scarce, especially near major population centers where low latency is critical. Planning permission can take years, as local communities often resist the construction of large, energy-hungry facilities. Grid connections are perhaps the most painful bottleneck. In many parts of the world, the electrical grid is already at capacity. Connecting a new datacenter that might draw 50 or 100 megawatts of power requires massive upgrades to substations and transmission lines. Segro, one of the UK’s major commercial property developers, revealed that it faced delays often running into years getting its server farm projects wired up to the national grid.
Now, add material shortages and price hikes on top of these delays. A project that was already facing a 3-year wait for a grid connection now also has to contend with steel prices that have jumped 20 percent and transformers that will take 30 months to arrive. The cumulative effect can push the total project timeline from 4 years to 6 or 7 years, dramatically increasing the total cost and delaying the revenue that the datacenter would generate.
The Skills Shortage Dimension
Another pre-existing challenge is the shortage of skilled labor. Building a datacenter requires electricians, welders, HVAC technicians, and project managers who understand the unique demands of these facilities. The labor market was already tight before the war. Now, with projects stretching out over longer periods, the demand for these skilled workers is even higher, driving up labor costs. A project manager might find that they cannot hire enough electricians to work on the electrical infrastructure because all the available workers are already booked on other, longer-duration projects. This creates a cascading effect where delays in one area cause delays in another.
Impact 5: The Long Tail of Geopolitical Uncertainty
The final and perhaps most insidious impact of the Iran war is the long-term uncertainty it creates. Even if the Strait of Hormuz were to reopen tomorrow, the effects would not disappear quickly. Oskar Lampe warns that “the current situation is unlikely to ease quickly, as it will take a while for disrupted transport routes, energy price inflation and volatile raw material markets to recover.” This means that the iran war datacenter cost impact will be felt for years, not months.
Why Recovery Takes So Long
Think of the global supply chain as a complex network of pipes. When one major pipe is blocked, the entire system adjusts. Ships are rerouted, factories find new suppliers, and warehouses empty their inventories. But when the blockage is removed, the system does not instantly snap back to its previous state. The rerouted ships need to return to their original routes. The factories that switched to alternative suppliers need to rebuild relationships with their original partners. The warehouses that ran dry need to be restocked, and that takes time. In the case of the Iran war, the blockage is not just a physical one; it is a perceptual one. Investors and insurers will now view the region as higher risk, which will increase the cost of shipping insurance and financing for any project that relies on Middle Eastern supply chains.
Furthermore, the war has accelerated a trend toward supply chain diversification. Companies that previously relied on a single source for a key material are now actively seeking alternatives. This is a healthy long-term strategy, but it is disruptive in the short term. Shifting to a new supplier requires qualification, testing, and negotiation, all of which take time and money. For a datacenter project that is already in the construction phase, switching suppliers mid-stream can be extremely difficult.
Diversification as a Strategic Imperative
Lampe advises development teams to “diversify supply chains where possible.” This means not putting all eggs in one basket. For example, a project that was sourcing all its steel from a single mill in a conflict-adjacent country should now be actively seeking secondary sources from other regions, even if they are more expensive. Similarly, for oil-based materials like certain types of insulation, waterproofing membranes, and asphalt, Lampe notes that “technically equivalent, non-oil-based variants exist. Potentially more expensive to procure, but available and in many cases already geared towards future sustainability requirements.” This is a silver lining: the crisis is forcing the industry to adopt more sustainable materials, even if the immediate cost is higher.
Practical Action: Building Price Escalation Rules
One of the most practical steps a project team can take is to build clear price escalation rules into all contracts. A standard fixed-price contract is extremely risky in the current environment. If material costs rise by 20 percent, the contractor bears the entire burden, which could lead to bankruptcy or project abandonment. Instead, contracts should include a clause that allows the price to be adjusted based on a publicly available index, such as the producer price index for steel or cement. This shares the risk between the client and the contractor, making it more likely that the project can continue even if costs rise unexpectedly.
A New Reality for Datacenter Construction
The Iran war has introduced a new and powerful variable into the already complex equation of datacenter construction. The five impacts discussed here—the 20 percent material cost spike, the slashed delivery volumes, the extended lead times for plant equipment, the compounding effect of pre-existing challenges, and the long tail of geopolitical uncertainty—are not temporary blips. They represent a structural shift in the cost and risk profile of building server halls. For anyone involved in this industry, from the project manager on the ground to the CFO in the boardroom, the message is clear: adapt or face significant delays and budget overruns. The era of assuming stable supply chains and predictable material costs is over. The new era demands proactive procurement, diversified supply chains, flexible contracts, and a clear-eyed understanding of the iran war datacenter cost reality.
