How to prevent delays in data center construction | Nialli

Written by Rick Kennedy | Sep 29, 2026, 8:28:17 PM

Surging AI demand has led to an increased volume in data center construction projects, presenting risks around long-lead MEP equipment sourcing, grid constraints and trade labor shortages. Many costly project delays are avoidable — stemming from disconnected top-down scheduling, untracked constraints and broken field commitments rather than unforeseeable field conditions. Forward-thinking owners and general contractors protect on-time project delivery by adopting collaborative planning methods and frameworks. Digital platforms like Nialli™ Visual Planner can improve consistency in deploying these approaches across mission-critical builds. 

The data center industry is entering the most significant growth period yet in its short history. Driven by cloud computing, artificial intelligence and digital transformation, the demand for new capacity continues to accelerate. Owners and contractors are being asked to build more facilities, more quickly and with greater complexity than ever before.

At the same time, project teams face mounting pressure from every direction. Schedules are becoming even more compressed. Labor remains difficult to secure in many markets. Long-lead equipment sourcing can introduce uncertainty into even the best-managed projects. Power infrastructure requirements are becoming increasingly complex. Mechanical, electrical and cooling systems continue to evolve. Commissioning and start-up activities demand greater coordination.

Hardly a day goes by without you hearing about a data center project delay. None of these issues are new — what is new is the scale of the opportunity and the speed at which organizations are expected to deliver.

While no team can fully eliminate uncertainty, high-performing organizations consistently stack the deck in their favor. They create planning processes that expose risks earlier. They establish cultures built around reliable commitments. They monitor project health continuously. And they learn from every project they complete.

What are the biggest challenges impacting data center project delivery?

Delivering data center projects on time and within budget has become increasingly complex as compute demand surges. Today’s general contractors and mission-critical developers must navigate substantial data center construction challenges including:

  • Power availability and grid interconnection: Substation queues and power capacity limits often cause multiyear lead times, forcing builders to incorporate on-site substations, microgrids or alternative power sources to get projects delivered on time.

  • Long-lead procurement: Critical MEP equipment such as high-voltage transformers, switchgear, generators and liquid cooling systems can frequently carry lead times of 12 to 24 months, making early procurement essential.

  • Specialized labor shortages: Escalating demand for trade labor has created acute shortages of high-voltage electricians, mechanical installers, fiber technicians and commissioning agents, especially in secondary and rural markets.

  • Compressed design cycles and scope creep: Rapid advancements in computing and direct-to-chip liquid cooling require design adaptations in the middle of projects, increasing the risk of clashes and rework.

  • Permitting, zoning and approval constraints: Increased public backlash toward data center construction is driving regulatory scrutiny around power consumption, water usage and community impact, all of which can stall site development approvals.

Avoidable surprises: The number one data center project delivery barrier

Many project risks are unavoidable. What can be prevented, however, is being caught off guard by issues that should have been visible weeks or months earlier. Many project delays can ultimately be traced back to incomplete planning, unresolved constraints, poor coordination or unreliable commitments. In these situations, the delay itself is usually not the root cause. It is the visible outcome of avoidable problems that have accumulated over time.

Individually, these issues may appear minor. Collectively, they result in major schedule impacts. This is why leading project teams focus so heavily on planning reliability. Their goal is not simply to react to problems — it’s to identify and address problems before they affect production.

Three ways data center project teams can improve delivery

  1. Treat planning as a competitive advantage

    For many years, construction planning was viewed primarily as a scheduling exercise. Today, the most successful data center project owners approach planning very differently, recognizing that schedules alone don’t drive project success. People do.

    The teams performing the work possess critical information about constraints, sequencing requirements, resource availability and execution risks. Individual trades have domain expertise. When these voices are brought into the planning process early and often, project tasks gain visibility that cannot be achieved through top-down scheduling alone.

    This is one reason why collaborative planning methodologies such as Lean construction, the Last Planner System®, pull planning and other commitment-based approaches continue to gain traction across the industry. These methods engage the people closest to the work, improve coordination between stakeholders and create greater confidence in project commitments.

    The objective is straightforward: Create a shared understanding of what can be completed, what must happen next and what obstacles must be removed before work begins. Project teams that achieve this consistently create more predictable outcomes.

  2. Value field-level commitments over line items in a schedule

    Every project has a schedule. The difference between high-performing and struggling projects often comes down to whether commitments made within that schedule are delivered. Reliable commitments form the foundation of predictable project execution.

    When trades consistently complete the work they promise to complete, downstream activities remain on track. Coordination improves. Workflow becomes more stable. Teams gain confidence in the plan. When commitments are frequently missed, uncertainty spreads quickly. One missed activity can delay multiple trades. One unresolved issue can impact an entire sequence of work. This is why successful teams spend significant time measuring and improving commitment reliability rather than simply tracking milestone dates. They understand that high performance in a project schedule is ultimately the result of thousands of individual commitments being kept.

  3. Create early-warning systems

    The best project teams don’t wait until a critical milestone is missed before taking action. Instead, they create visibility into project health long before schedule problems become obvious. They track planning reliability. They monitor constraints. They analyze commitment performance. They identify trends and recurring issues. Most importantly, they use data to understand whether project schedule performance is improving or deteriorating over time.

    This creates an early-warning system that allows leaders to intervene while options still exist. By the time an executive dashboard shows a major schedule impact, the underlying causes have been identified and addressed. Organizations that identify risks earlier have more opportunities to adapt, recover and protect project outcomes.

How can data center owners facilitate project delivery improvements?

Owners have an important role to play in improving project performance. Too often, owners receive visibility only after problems have already developed. For greater transparency, owners should be comfortable asking the following questions:

  • How are commitments being made?

  • How are constraints being identified and removed?

  • How is planning reliability being measured? Is it improving?

  • What emerging risks are visible today?

  • What is being done now to prevent tomorrow’s delays?

Owners also need to be active participants in creating a collaborative planning environment where project teams can succeed. Here are six ways to make this happen:

  1. Share insights from past projects

    Many owners will have extensive experience from previous projects and can provide valuable insights into what worked, what didn’t and where challenges emerged. Sharing these lessons learned can help contractors avoid repeating mistakes and identify risks earlier in the planning process.

  2. Set management expectations up front

    Owners can set clear expectations up front on how projects will be managed — not simply how progress will be reported. For instance, owners can specify in RFPs that collaborative planning practices must be used.

  3. Hire an experienced owners’ representative

    Not all owners’ reps are created equal. Look for representatives with experience in data center construction or projects of similar complexity. They should play an active role in the planning process and not simply report on progress made. This includes sitting in on weekly planning meetings, observing pull planning sessions and understanding how constraints are affecting upcoming work to resolve them or develop workarounds.

  4. Be responsive in decision-making and resolving constraints

    Many project setbacks are caused not by the teams responsible for the construction, but by the incomplete information or decision-making delays stemming from the owner’s side. This includes design clarifications, operational requirements, procurement approvals, site access, utility coordination and stakeholder alignment. Work grinds to a halt if these constraints do not get addressed proactively. An engaged owner can significantly reduce these delays through rapid response and maintaining visibility into upcoming barriers.

  5. Maintain a culture of transparency

    Project teams perform best when they feel comfortable raising concerns early. If discussing risk is viewed as a failure, problems tend to remain hidden until they reach a boiling point. When owners encourage honest conversations about emerging challenges and foster a transparent decision-making environment, teams are willing to speak up early and often about emerging problems. Issues can then be identified and addressed before they affect critical milestones.

  6. Focus on real-time project metrics and leading indicators

    Most project reports provide an excellent explanation of what has already happened. The more valuable discussion is around what should happen next. Owners must maintain a close eye on the work unfolding at the ground level, monitor constraint logs and track whether work commitments accurately reflect tasks completed. If tasks are getting marked as incomplete, find out why and dig for root causes as early as possible.

The most successful owners recognize that rigorous planning requires proactive risk management. By participating in the planning process, sharing lessons learned, supporting collaborative practices and helping remove obstacles early, owners can significantly improve the odds of success.

What can general contractors do differently to improve data center project delivery?

General contractors face enormous pressure to deliver increasingly complex projects at unprecedented speed. The solution is not simply working harder — it’s creating better production systems.

Here are four methods general contractors can use to build stronger planning systems:

  1. Foster a culture of continuous improvement and collaboration

    Culture plays a critical role in project success. Contractors who consistently deliver challenging projects create cultures where process, transparency and continuous improvement are valued as highly as technical expertise. Raising issues, asking questions and admitting to mistakes are seen as a core responsibility of every team member, not a sign of weakness. Missed commitments are examined as opportunities to learn — not to assign blame. Project performance improves when teams focus on understanding and addressing root causes rather than reacting to symptoms.

  2. Invest in Lean construction expertise

    Many contractors have found value in having experienced Lean construction specialists on staff or leveraging the services of collaborative planning consultants. These individuals act as facilitators to help establish planning discipline, improve coordination and coach project teams on commitment-based planning practices. They help teams shift into a production planning mindset rather than simply managing schedules.

  3. Set frameworks and expectations up front

    Contractors should establish clear expectations around planning processes before work begins. Regardless of the planning system the team is using, success depends on shared commitment to the process. Every participant should understand how planning sessions will be conducted, how commitments will be made, how constraints will be managed and how performance will be measured. While there is tremendous pressure to begin work as quickly as possible, investing time up front to establish planning practices, clarify expectations and build relationships can prevent far larger delays later. Conversations on these topics can be just as important as the technical planning work itself.

  4. Look for opportunities to learn and continuously improve

    Contractors should evaluate performance through the lens of learning and continuous improvement by asking the following questions:

    • Which planning practices are producing better results?

    • Which trades consistently keep commitments?

    • Where are recurring bottlenecks occurring?

    • Which constraints appear repeatedly across phases of work?

    • What lessons should be carried into the next phase or project?

Project data should be treated as a strategic asset. It is important that contractors use planning metrics and commitment performance to understand what is working, where improvement is needed and how future phases and projects can be delivered more effectively.

Successful contractors understand that predictable outcomes are created through disciplined processes that identify risks early, improve coordination and support reliable execution. When projects depend on a handful of individuals to continuously solve emergencies, the project becomes vulnerable. When projects rely on strong planning systems, the entire team becomes more capable of managing complexity.

How digital tools can help with data center project delivery

The principles behind successful project delivery are well established. Bring the right people into the planning process. Make reliable commitments. Identify and remove constraints. Measure performance. Learn continuously. But how do you execute these steps consistently across a project that may involve hundreds of people, dozens of companies and thousands of individual activities? This is where digital tools for collaborative planning can assist

Nialli™ Visual Planner provides a collaborative planning environment that brings project teams together around a shared plan. Here are the three main ways in which this solution can help data center project teams:

  1. Bring everyone together, no matter the location

    Nialli Visual Planner helps bring project planners, managers, superintendents, trades and owners into the same planning conversation. Everyone shares real-time access to the plan, even if they can’t physically be together in the room. For teams that are in the room together, Nialli Visual Planner is purpose-built for collaboration. It can run across multiple interactive displays positioned together and support multiple users interacting at the same time, making the software hands-on and easy to use for everyone involved.

  2. Make visible, reliable commitments

    Nialli Visual Planner supports commitment-based planning by helping teams make commitments visible on a planning wall with digital sticky notes. Everyone can see what was promised, what was completed and emerging risks. This transparency creates accountability while encouraging the conversations necessary to address problems early.

  3. Transform site-level planning sessions into actionable data

    One of the largest challenges with collaborative planning methods is accurately tracking project progression at the ground level. If teams are using paper sticky notes for pull planning or weekly status updates, calculating metrics like Percent Plan Complete (PPC) is labor intensive and prone to error. Nialli Visual Planner automatically captures this information, turning it into meaningful project intelligence. Rather than relying on anecdotal observations or intuition, teams can evaluate actual performance trends and make informed decisions based on objective data. These insights can be applied to future projects, enabling continuous improvement over time.

Better planning. Better commitments. Better outcomes.

Data center projects will always present a level of uncertainty. No technology, methodology or process can eliminate every challenge. What organizations can do is improve the quality of planning, strengthen commitment reliability, create visibility into emerging risks and continuously learn from experience. That’s how successful teams stack the deck in their favor. By combining collaborative planning, commitment-based execution and practical performance data, Nialli Visual Planner helps project teams improve their ability to plan, commit, deliver and learn, turning a proven construction philosophy into a repeatable approach for better project outcomes.
