Why Detailed Infrastructure Planning Can Save Millions
A data center buildout is progressing smoothly—power systems installed, cooling infrastructure coming online, racks queued for delivery. Then someone notices the structured cabling design doesn’t align with the final equipment layout.
What should be a quick correction becomes a change order. And in data center construction, change orders never stay small.
That single revision ripples through the project: pathways are rerouted, containment systems modified, commissioning schedules delayed. In large-scale facilities, these mid-construction changes routinely erode timelines and budgets, adding six- or seven-figure costs that weren’t part of the original estimate.
The root cause isn’t poor installation—it’s incomplete planning.
When network and cabling specifications remain open-ended during design, they become moving targets in the field. Equipment connections shift, airflow conflicts emerge, and scalability suffers under temporary fixes. Each adjustment compounds cost and complexity across trades already working under tight power and schedule constraints.
Detailed preconstruction planning isn’t about overengineering—it’s about foresight. With the average U.S. data center now costing more than $220 million per facility, locking in cabling routes, airflow models, and load paths early prevents the “design-on-the-fly” scenarios that inflate budgets later. Because in data center construction, every change order costs three to five times more than getting it right the first time—a premium that can easily reach millions on today’s hyperscale builds.
The Domino Effect of Late Design Changes
When construction begins before all design elements are finalized, the smallest infrastructure adjustment can cascade into expensive rework.
Consider a typical late-stage modification:
- Adding or relocating network cabinets after containment systems are installed
- Changing cable pathways once trays and ladder racks are mounted
- Adjusting fiber routing when the raised floor or under-slab conduits are already in place
Each change forces teams to pause, redesign, and often re-permit. Crews must undo completed work, order new materials, and re-coordinate trades—all while project timelines slip.
According to Dodge Construction Network, on average, 30 percent of project revenue is lost because of unbilled and unpaid change orders, often stemming from incomplete early-stage planning. For hyperscale and colocation data centers, that translates into millions of dollars in avoidable expense and lost revenue from delayed commissioning.
Why Infrastructure Planning Is the First Line of Defense
The most efficient data center projects begin with a precisely defined scope and a unified design strategy. Before a single cable tray or rack is mounted, every connection point, pathway, and system component should be mapped, modeled, and validated across disciplines.
Comprehensive infrastructure planning enables project teams to:
- Lock in specifications early: Finalized designs limit scope creep and minimize change requests once construction is underway, helping maintain both budget and schedule.
- Model power and thermal performance: Early coordination between structured cabling, electrical, and mechanical systems ensures proper power distribution and airflow management—preventing hotspots and costly retrofits later.
- Standardize components and pathways: Using consistent assemblies, labeling, and routing simplifies procurement, promotes modularity, and reduces on-site installation errors.
- Coordinate trades in advance: When all stakeholders—from electricians to HVAC specialists—work from a shared, validated model, design and installation conflicts can be identified and resolved before construction begins.
This is the foundation of Hexatronic’s approach: pre-construction infrastructure modeling that aligns cabling architecture with airflow efficiency, power scalability, and future growth requirements—all within a fully integrated, build-ready design.
The Real Cost of a Change Order
It’s easy to underestimate how a single revision impacts cost. Beyond the direct material or labor adjustment, each change order carries hidden expenses:
| Cost Category | Example | Financial Impact |
| Labor Inefficiency | Technicians reroute or re-pull fiber, delaying parallel trades | Schedule slippage and overtime costs |
| Material Waste | Discarded cable, fittings, or trays from abandoned pathways | Lost inventory and reordering delays |
| Design Revisions | Engineering time to update drawings and documentation | Added design fees |
| Operational Delay | Delayed commissioning or tenant turnover | Lost monthly revenue, reputation risk |
Even a modest change order—say, rerouting 50 fiber runs after installation—can cost up to 5 to 10 percent extra (with up to 25 percent for complex builds) in labor and materials. Multiply that across multiple systems or rooms, and the cost curve escalates rapidly.
Early collaboration and design discipline prevent these compounding inefficiencies long before they hit the budget sheet.
Design Once, Build Right
The path to eliminating costly rework starts with design precision. Detailed upfront planning transforms potential clashes into coordinated solutions and aligns every stakeholder—from general contractors to structured cabling teams—before any hardware hits the site.
Key best practices include:
- Integrated 3D and BIM Modeling: Spatial coordination through Building Information Modeling (BIM) validates mechanical, electrical, and cabling pathways in advance, minimizing conflict and rework during installation.
- Pre-Terminated and Modular Solutions: Factory-assembled cabling systems ensure consistent quality, faster deployment, and reduced risk of on-site termination errors—accelerating installation and maintaining design integrity.
- Documented Infrastructure Standards: Clear documentation for labeling, pathway routing, and load planning prevents miscommunication and supports long-term maintenance and scalability.
- Phased Design Validation: Scheduled design reviews at each project phase align evolving requirements across trades before procurement and construction begin, reinforcing accountability and decision traceability.
When design and cabling specialists collaborate early, every installation reflects the original design intent—making “change order” a rare exception rather than a costly expectation.

Plan Smarter to Build Stronger
In today’s rapidly expanding data center market—projected to surpass $269 billion globally by 2025—predictability is more than a competitive edge; it is a profitability driver. Each delay, design change, or rework directly affects ROI and operational uptime.
Disciplined, integrated infrastructure planning—especially for structured cabling—remains the most effective protection against these cost spirals. The projects that succeed are those that define every pathway, validate every design assumption, and coordinate every trade before construction begins.
Hexatronic partners with data center developers, contractors, and operators to make that early precision achievable. By uniting cabling architecture, airflow design, and scalability objectives into one cohesive plan, Hexatronic helps clients achieve consistency from blueprint to build.
