Data centres are among the most complex buildings constructions. Every second of downtime has financial consequences, making reliability, compliance and maintainability just as important as the technology they house.

Behind every resilient data centre is an enormous volume of technical documentation. Mechanical, electrical, hydraulic, fire protection and controls systems must all be accurately documented, tested and handed over to enable operators to maintain uptime throughout the facility’s lifecycle.

For builders, contractors and owners, producing complete and accurate documentation has become one of the most challenging aspects of project delivery.

Why Documentation Matters in Data Centres

Unlike commercial offices or retail buildings, data centres operate continuously.

Power systems, UPS infrastructure, standby generators, cooling systems, fire detection, suppression systems and Building Management Systems all operate together to provide uninterrupted service. If information is missing or incorrect, maintenance teams lose valuable time diagnosing faults or carrying out planned maintenance.

Poor documentation can result in:

• Delayed commissioning and practical completion
• Increased operational risk
• Longer maintenance shutdowns
• Incomplete asset registers
• Compliance issues during audits
• Reduced confidence in facility handover

For mission-critical facilities, documentation is not simply a contractual requirement. It is an operational necessity. (DC Geeks)

The Biggest Documentation Challenges

Thousands of Critical Assets

Large hyper scale data centres can contain tens of thousands of maintainable assets. Each item requires:

• Manufacturer information
• O&M procedures
• Test certificates
• Warranty documentation
• Commissioning records
• Preventative maintenance requirements
• Asset identification

Managing this information across dozens of subcontractors is a major coordination exercise.

The D&A Solution

Dewick manages documentation collection through its nucleus online portal, allowing subcontractors to upload information throughout construction rather than waiting until project completion. This reduces last-minute document chasing while improving document quality and consistency.

Complex MEP Coordination

Data centres contain some of the most sophisticated building services in construction. Typical systems include:

• HV and LV electrical infrastructure
• UPS systems
• Diesel generators
• Chillers
• CRAH and CRAC units
• Building Management Systems
• Fire suppression systems
• Security and access control
• Network infrastructure

Each discipline produces its own documentation, often in different formats. Without a structured process, inconsistencies quickly develop between drawings, asset schedules and manuals.

The D&A Solution

Our engineering-led review process ensures documentation aligns across all disciplines, creating a coordinated handover package that reflects the installed facility.

Commissioning Generates Massive Volumes of Data

Commissioning on a data centre is significantly more rigorous than on traditional commercial buildings.Testing typically includes:

• Factory Acceptance Testing (FAT)
• Site Acceptance Testing (SAT)
• Integrated Systems Testing (IST)
• Generator load testing
• UPS testing
• Black Building testing
• Failover simulations
• Witness testing

Every test produces reports, certificates and evidence that must be retained as part of the final project record. Without structured management, critical information can easily become fragmented or lost.

The D&A Solution

D&A compiles and structures commissioning records into comprehensive Commissioning Plans and Building Handover Manuals, making them easy to navigate long after practical completion.

Operations Teams Need Information They Can Actually Use

Many facilities receive thousands of pages of documentation that are technically complete but difficult to navigate. Operations teams don’t need to search through hundreds of PDFs during a critical fault. They need fast access to:

• Equipment locations
• Maintenance procedures
• Spare parts
• Shutdown sequences
• Warranty information
• Asset histories

Research consistently shows that one of the biggest barriers to effective facilities management is information accessibility, not the lack of information itself. (MDPI)

The D&A Solution

Dewick structures information around operational use rather than simply compiling contractor submissions. Deliverables include:

• O&M Manuals
• Asset Registers
• Preventative Maintenance Log Sheets
• Maintenance Matrix
• As Installed Drawings
• Digital documentation through nucleus

The result is documentation that supports facilities management from day one.

Supporting Digital Asset Management

Modern data centres increasingly rely on digital asset management, BIM, CMMS and Digital Twin platforms. However, these systems are only as effective as the information supplied during project handover. Industry research shows that poorly defined asset information requirements often leave facility managers with incomplete or unusable digital records, requiring costly post-handover data cleansing.

Dewick helps bridge this gap by delivering structured, quality-assured asset information that supports long-term operational systems rather than simply meeting contractual requirements.

Dewick Experience

Dewick has supported documentation delivery for complex mission-critical projects where accuracy, coordination and compliance are essential.

One example is the DCI Data Centres Adelaide Expansion, where Dewick delivered comprehensive construction documentation to support project completion and long-term facility operation.

Drawing on decades of experience across healthcare, defence, transport, commercial developments and critical infrastructure, Dewick & Associates understands the level of coordination required to produce accurate documentation for technically demanding facilities. Whether the project is a hyperscale data centre, edge facility or enterprise server environment, Dewick provides:

• Building Handover Manuals
• Mechanical, Electrical and Fire O&M Manuals
• Commissioning Plans
• Asset Registers
• Preventative Maintenance Log Sheets
• Maintenance Matrix
• Digital document management through Nucleus
• Engineering review and quality assurance

In a mission-critical environment, documentation is far more than a contractual deliverable. It becomes the operational blueprint for the entire facility.

Accurate manuals, structured asset information and comprehensive commissioning records enable operators to maintain uptime, respond to incidents quickly and manage assets with confidence for years after construction is complete.

By combining experienced technical authors, qualified engineers and a purpose-built digital documentation platform, D&A delivers construction documentation that supports not only successful project handover but the ongoing performance of some of the world’s most demanding facilities.
