Data center construction services involve designing, building, and commissioning facilities to ensure uninterrupted operation for industries like finance, healthcare, and AI. These projects require careful planning, specialized infrastructure, and skilled professionals to meet growing demands. Here's what you need to know:
With the global data center market projected to grow from $250.8 billion in 2024 to $417.9 billion by 2030, efficient execution is more important than ever.
Data Center Construction: Key Phases, Deliverables & Common Gaps
Data center construction involves a broad range of services, from initial planning to final handover. Understanding this entire process is crucial for avoiding unexpected challenges. With the global data center construction market expected to grow from $250.8 billion in 2024 to $417.9 billion by 2030, the stakes for executing these projects efficiently and effectively are higher than ever.
Before breaking ground, teams must assess the project's feasibility. This phase includes site selection, where factors like power grid access, fiber connectivity, water availability, and local zoning regulations are evaluated. Engineers then create detailed designs, including MEP blueprints, rack layouts, and airflow simulations using computational fluid dynamics (CFD) models.
Utility coordination is a critical aspect of preconstruction. In certain U.S. markets, grid connection wait times can exceed four years. Delays in high-demand areas like Northern Virginia can cost developers over $500,000 per month in lost Net Operating Income. To avoid such setbacks, utility discussions should begin 18–24 months before the power is needed, and written "will serve" commitments should be secured before finalizing designs.
"Speed to power has replaced speed to build." - Trevor Walker, PE, SE, Vice President, JLL
Permitting and approvals also play a significant role, often becoming a bottleneck. Depending on the location, this phase can take anywhere from 6 to 18 months. For more details on how early decisions can influence project outcomes, check out iRecruit's guide on data center construction.
Once planning is complete and utility commitments are in place, the focus shifts to building reliable and scalable core systems.
Electrical systems, including utility feeds, substations, medium-voltage switchgear, transformers, UPS systems, and backup generators, typically account for 40–45% of a data center's construction costs. Mechanical and cooling systems add another 15–20%.
The table below highlights how each infrastructure component contributes to reliability and scalability:
| Infrastructure System | Critical Components | Role in Reliability/Scalability |
|---|---|---|
| Electrical | Switchgear, UPS, Generators, PDUs | Provides continuous power with N+1 or 2N redundancy |
| Mechanical | Chillers, CRAH units, Liquid Cooling | Handles thermal loads; liquid cooling supports high-density AI scaling |
| Network | Fiber pathways, Meet-me rooms | Ensures low-latency connectivity and carrier diversity |
| Fire/Life Safety | Smoke detection, Gas suppression | Protects critical hardware from fire and smoke damage |
AI workloads are redefining data center infrastructure. While traditional facilities were built to support 10–20 watts per square foot, AI-optimized centers now require 150–200 watts per square foot. This shift demands innovative cooling strategies, particularly direct-to-chip liquid cooling. For instance, Meta's AI data center in Temple, Texas, was designed to support 1.3 million GPUs, necessitating a complete overhaul of its power and cooling systems.
Another challenge is the extended lead time for key components like transformers, switchgear, and generators, which now ranges from 25 to 55 weeks, with some quotes exceeding 100 weeks. To avoid delays, these items should be ordered during the design phase rather than waiting for permit approvals. Early procurement is essential for fast-track projects and aligns with critical project timelines.
Once core systems are installed, ensuring their operational readiness becomes the top priority. Commissioning follows a structured Level 1–5 process, beginning with factory acceptance testing and progressing through site acceptance to full functional performance tests. The most rigorous step is Integrated Systems Testing (IST), where full-load failover scenarios and power outage drills confirm that redundancy systems function as intended.
"A data center is only successful when systems perform under load, redundancy behaves as designed, and commissioning validates operational readiness." - iRecruit
Final turnover includes delivering as-built documentation, operations and maintenance (O&M) manuals, and comprehensive training for facility staff. Skipping this phase often leads to operational issues within the first year. Engaging commissioning agents early in the design process, rather than at the project's conclusion, is one of the best ways to prevent rework and keep the project on schedule. Together, thorough testing and detailed documentation lay the groundwork for long-term operational success.
Each phase of a data center construction project must produce clear, documented deliverables. These outputs ensure accountability, streamline handoffs, and support the operational readiness of the facility. Without them, stakeholders lose visibility, assumptions replace facts, and critical transitions falter. Let’s break down the key deliverables that keep these projects on track.
The Basis of Design (BOD) lays the groundwork by defining IT load, redundancy targets, and environmental parameters. From this foundation, engineering documents like single-line electrical diagrams, mechanical layouts, CFD airflow models, and rack-level white space plans are developed.
Two often-overlooked but essential documents are:
When these documents are missing or inaccurate, field crews and operations teams are left guessing, which can lead to costly errors. For a deeper dive into how early design choices shape outcomes, check out iRecruit’s guide on data center construction.
These design documents are critical for accurate scheduling and budgeting.
A Critical Path Method (CPM) schedule isn’t just a reporting tool; it’s a real-time control system for managing execution. As Leopard Project Controls explains:
"In that environment, the construction schedule is not a reporting tool. It is a control system."
A well-constructed schedule is logic-driven, prioritizing system readiness milestones like energization and mechanical completion over simple trade availability. Cost plans must reflect the same level of detail, locking in specifications early.
Long-lead equipment - such as switchgear, chillers, and UPS systems - currently requires 36 to 48 weeks for delivery. To avoid delays, procurement milestones for these items must be integrated into the CPM schedule. Overlooking this step can create hidden critical paths that emerge too late to address.
Accurate schedules and budgets mitigate schedule risks and pave the way for a well-organized project closeout.
Turnover is often where projects falter. A comprehensive closeout package includes:
These materials are essential for the operations team to manage the facility effectively from day one. According to Leopard Project Controls:
"Turnover is not administrative housekeeping. It is a structured scope of work that includes documentation, inspection sign-offs, labeling verification, training sessions, spare parts delivery, and system certification."
To avoid last-minute chaos, treat closeout as a formal scope of work within the CPM schedule. Include milestones for compiling documentation, completing inspections, and conducting training sessions. Teams that plan for closeout early ensure a smoother transition to operations, reducing risks and inefficiencies.
Even with careful planning, data center projects often hit major roadblocks during execution. Success in these projects hinges on experienced professionals managing every phase. When expertise is lacking, issues like workforce shortages, miscommunication, and scaling challenges can derail progress. Let’s dive into the key areas where these gaps arise.
One of the biggest hurdles in data center construction today is finding skilled professionals. Roles like project managers with mission-critical experience, MEP (mechanical, electrical, and plumbing) coordinators, commissioning leads, superintendents, and electrical infrastructure experts are in short supply. These projects demand individuals who are well-versed in managing complex, power-intensive builds. As The Birmingham Group explains:
"A good superintendent on a standard office project is not automatically the right superintendent for a dense, schedule-sensitive, power-heavy data center build."
The workforce issue is compounded by an aging construction workforce - over 20% of U.S. construction workers will be 55 or older by 2024 - and the projected need for an additional 349,000 workers by 2026. As facilities increasingly integrate AI systems, requiring higher cooling and electrical capacities, this talent shortage becomes even more critical. In fact, over half of all data center projects in 2025 experienced delays of three months or more, with workforce gaps being a primary factor. For insights on how companies are addressing these challenges, iRecruit offers a helpful guide on jobs and workforce trends.
Beyond staffing issues, poor communication is another frequent stumbling block. Data centers rely on highly interconnected systems, so even a small error - like a misrouted duct or misplaced cable - can create a domino effect across multiple teams, leading to costly rework. The root cause? Disjointed communication and outdated documentation.
Version control is a common trouble spot. When teams rely on different drawing revisions or unstructured email threads to manage RFIs (requests for information), mistakes can grind progress to a halt. These issues are particularly risky during commissioning, where time pressures are at their peak and errors are most expensive to fix. Additionally, last-minute value engineering changes - made without consulting operations or design teams - can weaken fault tolerance and lead to expensive fixes down the road.
Scaling up project teams introduces a unique set of risks. Simply adding more workers doesn’t guarantee smoother execution. The real challenge lies in maintaining execution capacity - the amount of quality work completed per labor hour. Without skilled leadership, rapid team expansion can lead to overstretched management, reactive oversight, and burnout.
Fast-track schedules only add to the complexity. Compressing timelines forces multiple trades to work simultaneously in tight MEP zones, increasing safety risks, reducing quality, and slowing productivity. Large-scale campus projects in less populated areas face another hurdle: specialized workers are often reluctant to relocate, and the local workforce may lack the skills needed for multi-gigawatt builds.
"Hiring more people does not automatically reduce risk. The timing, experience, and alignment of leadership roles matters far more than headcount." - iRecruit
Here’s a quick snapshot of the most common scaling challenges and their causes:
| Scaling Challenge | Root Cause |
|---|---|
| Labor scarcity | Limited pool of mission-critical experts |
| Communication gaps | Fragmented tools, version control issues |
| Schedule compression | Delays in long-lead equipment, trade stacking |
| Commissioning risk | Treating testing as an afterthought |
| Trade interference | Poor coordination in dense MEP zones |
Figuring out where projects tend to falter is just the start. To truly improve outcomes, you need strategies that tackle issues like coordination breakdowns, procurement risks, and talent shortages. Here's how you can set the stage for success by putting the right systems, processes, and people in place before problems arise.
Unified delivery models can effectively address the coordination and communication gaps that often derail projects. By aligning accountability for both design and construction from the very beginning, you eliminate the blame game when things go wrong. When one team takes charge of procurement, MEP coordination, and commissioning, there’s no room for miscommunication or finger-pointing.
A great example of this approach is the Crusoe Abilene Data Center Campus in Texas. DPR Construction and its partners used a risk-sharing, multi-prime delivery model to complete all data halls in less than 18 months. They involved trade partners early while the design was still flexible, and prefinished exterior wall panels helped them install over 600 panels in just seven days - a job that usually takes eight weeks.
"Delivery strategy is now business strategy." - Mark Whitson, President, DPR Construction
The principle at play here is engineering concurrency - overlapping key phases like design, procurement, and construction instead of handling them one at a time. Treating projects as repeatable programs rather than one-off efforts also allows teams to reuse proven designs and standardized components, boosting both speed and safety.
For many projects, long-lead equipment like generators, switchgear, and UPS systems often dictates the timeline. Procurement should be treated as a critical path activity, with vendor milestones tracked as carefully as on-site progress.
Here’s how to stay ahead:
Utility coordination is another area that demands urgency. In some U.S. markets, securing grid connections can take more than four years. That’s why early "will serve" commitments from utilities should be secured well before finalizing the design.
"On a fast-track mega project, losing a day is like losing a week, and losing a week is like losing a month." - Vikesh Handratta, Project Executive, DPR Construction
Commissioning milestones should also be built into the master schedule from the outset. Bringing in commissioning agents during the design phase - not just at the handover stage - helps define testing requirements early and avoids costly rework when system conflicts are discovered under live conditions.
While efficient scheduling and procurement can reduce delays, having the right talent in place is just as important.
The success of mission-critical projects hinges on having the right people in the right roles. Talent shortages are a major challenge, and workforce planning needs to be treated as a core part of risk management. That means forecasting staffing needs early, mapping them across all phases of the project, and treating hiring as a critical path activity.
"Hiring can't be reactionary. Just like materials and scheduling, staffing needs to be forecasted early." - FootBridge
Building effective teams requires a mix of core full-time staff for continuity and specialized contractors to handle peak phases like commissioning or utility tie-ins. Some of the hardest roles to fill right now include electrical engineers, MEP project managers, commissioning engineers, and controls specialists. These are positions that can’t be filled at the last minute when a critical phase is underway.
Recruiting platforms like iRecruit.co specialize in mission-critical construction roles, offering pre-vetted professionals for positions like project managers, MEP coordinators, commissioning leads, and field superintendents. Their success-based model includes a 90-day search credit, reducing the risk of hiring mistakes at critical moments - when a bad hire could cost far more than the placement fee.
"In data center construction, talent availability directly affects execution risk." - iRecruit.co
Constructing a data center is no small feat - it demands meticulous coordination of power, cooling, redundancy, and controls from the very first day of operation. Success lies in systems that can handle real-world demands, redundancy that aligns with design expectations, and thorough commissioning to ensure everything is ready to go. These principles guide every step, from planning to procurement to final delivery.
Key strategies like MEP coordination, early commissioning, and proactive procurement are essential to navigating long lead times and avoiding delays. With around 100 GW of new capacity expected to come online globally between 2026 and 2030, there’s less and less room for missteps.
The challenge doesn’t stop there. Execution risks grow when skilled talent is hard to find. As noted earlier, addressing workforce shortages is just as important as integrating systems. In North America alone, there’s an estimated shortfall of 500,000 skilled workers needed to meet current demand. The hardest positions to fill - commissioning engineers, MEP project managers, and controls specialists - are often the ones that make or break a project’s timeline and budget.
"A successful data center project is built long before the foundation is set. Every strong project begins and ends with people, partners, and power." - Trevor Walker, PE, SE, Vice President, JLL
Start utility coordination as early as the site selection phase - long before construction begins. Engaging in pre-application meetings with utility providers at this stage is key. These meetings help confirm substation capacity and secure your place in the interconnection queue, a process that can take anywhere from 6 to 24 months for larger projects.
When selecting a site, focus on locations with adequate grid capacity. It's also essential to ensure the utility's reserve margin is above 15%, as this provides a cushion for future demands. Finally, treat interconnection agreements as critical items in your project timeline to avoid delays and keep everything on track.
During the design stage, prioritizing and ordering essential equipment is a must, especially when it has a direct impact on the project timeline. Some of the key items that often require early attention include:
These items typically come with extended manufacturing lead times. To avoid delays, it’s important to procure them early, aligning with current market forecasts.
A complete data center turnover package needs to have detailed documentation to guarantee a smooth shift from construction to daily operations. Some key elements include:
Additionally, it's crucial to provide proof that the facilities team has received and understood the necessary knowledge transfer. This step helps prevent any delays during the handoff and the go-live phases.
