The Ultimate Technical Due Diligence Checklist for Data Centres

 Imagine you're standing in an open field on the outskirts of a rapidly growing tech hub. The air is still, but the potential hum of servers, routers, and chilled air fills your imagination. This bare land may soon become a high-performance colocation hub or a hyperscale data center, but only if you get one thing right technical due diligence.

Before the first cable is laid, before a single line is drawn in Revit or AutoCAD, there's a phase of the project that feels invisible yet defines everything that follows. It’s the quiet, often overlooked hero of successful data center development: Technical Due Diligence (TDD).

Let’s unfold this story not as a checklist, but as a narrative that explores why it matters, how Desapex brings it to life, and the real value it delivers.

What is Technical Due Diligence?

Technical due diligence is a systematic, multi-disciplinary assessment that ensures a site is viable environmentally, legally, technically, and operationally for a data center. It involves investigating everything from power and fiber access to environmental risks, cooling feasibility, and land ownership.

It’s not just a checkbox exercise. It’s a lens through which investors, developers, and operators view risk and make confident, informed decisions.

Why It Matters for Data Center Projects

Think of a data center like a living organism. Its ability to survive and thrive depends on its ecosystem power, connectivity, cooling, land, security, compliance, and scalability.

Missing even one critical detail in the due diligence phase can create massive downstream costs, regulatory delays, or even project failure. It’s why some of the biggest names in hyperscale only shortlist sites after rigorous due diligence not before.

At Desapex, we’ve seen it all. From projects derailed due to lack of soil reinforcement plans to last-minute fire code rejections. With the rise in edge computing, AI workloads, and hyperscale demand, the stakes have never been higher.

The Blueprint of Certainty: Your Technical Due Diligence Essentials

Before a single design is drafted or a foundation stone is laid, there’s a framework that quietly shapes the entire future of your data center project, the technical due diligence checklist.

This isn’t just a set of tasks; it’s a diagnostic map that helps you spot risks, validate potential, and make confident decisions. It ensures your vision is backed by ground reality technically, legally, and environmentally.

To bring clarity and confidence to your decision-making, you need a structured and comprehensive approach technical due diligence for data centers as follows:

‍

1. Site & Land Assessment

  • Land title and ownership verification

  • Zoning and land-use compliance

  • Soil investigation and bearing capacity

  • Topographic survey

  • Flood zone and seismic risk assessment

  • Expansion potential and site accessibility

2. Power Feasibility

  • Distance to nearest substation (e.g., 132 kV)

  • Power availability and grid reliability

  • Renewable energy potential (solar/wind)

  • Generator backup feasibility and emission norms

  • Electrical load projections and redundancy planning

3. Connectivity & Fiber

  • Proximity to metro/dark fiber networks

  • Number of fiber providers

  • Fiber entry paths and points of presence (PoPs)

  • Redundant routing for uptime assurance

  • Future-proofing for higher bandwidth requirements

4. Cooling & Water Access

  • Water source (municipal, borewell, etc.)

  • Cooling strategy (air-cooled, water-cooled, hybrid)

  • PUE targets and energy efficiency benchmarks

  • Rainwater harvesting and water recycling potential

  • Impact of climate and ambient conditions

5. Regulatory & Environmental

  • EIA (Environmental Impact Assessment) clearance

  • Fire NOC and related permits

  • Building code and height restrictions

  • Emission, noise, and waste management compliance

  • Legal disputes or environmental encumbrances

6. Security & Location Risk

  • Site neighborhood assessment (industrial, residential, etc.)

  • Crime rate and civil unrest history

  • Proximity to high-risk zones (chemical plants, airports)

  • Site boundary and access control feasibility

  • Natural disaster vulnerability (floods, earthquakes)

7. Design & Build Feasibility

  • MW-per-acre density projection

  • Modular construction support

  • Space planning for chiller yards, substations, etc.

  • Accessibility for logistics and heavy equipment

  • Phased development possibilities

Traditional Approach vs BIM Approach

  Timely Incomplete Design Information Sharing and Communication : In traditional 2D CAD design, the different participants have to wait for each other’s design completion; the data deliverable are piled in silos before they can be exchanged between the design teams. In such a case, data can become obsolete, in other words, the data goes to waste. In contrast, In  BIM -based design, early and timely exchange of incomplete  information  between participants is enabled by sharing and integrating the  building information models  of the teams at any point in time. This allows real-time design adjustments and development. The information is then always up-to-date, and the clear design intent visualization facilitates communication between players and allows for  continuous information flow  instead of interrupting the batch flow. Idle Time The BIM-based design phases clearly show the reduction in delays as opposed to the  traditional  design...
