Phase 2: Technical Design

Introduction

With the strategic foundations established, the technical design phase translates the development vision into robust, high-performance infrastructure. Through integrated engineering, advanced modelling and coordinated digital design, we create resilient, efficient and scalable data centre environments that support long-term operational performance.

Our Services

Modular Design & DfMA

We provide comprehensive mission critical services, design and integration engineering for modular and prefabricated data centre infrastructure, including containerised power and cooling modules, electrical distribution blocks, and mechanical plant skids. Our DfMA approach encompasses electrical systems (UPS, switchgear, and generators), mechanical systems (chillers, cooling units, and ventilation), and their integration with on-site substations and utility connections, enabling rapid deployment and scalable infrastructure solutions for clients requiring speed, flexibility and operational certainty.

Enables rapid deployment through prefabricated infrastructure modules

Supports scalable solutions such as containerised power skids and modular cooling systems

Improves quality and consistency through controlled off-site manufacturing

Reduces on-site construction risk and programme delays

Enhances cost certainty and project efficiency

Minimises material waste and supports more sustainable construction methods

High-Density Cooling Solutions

We design advanced cooling solutions for high-density data centre environments supporting AI and cloud workloads at rack densities from traditional air-cooled configurations through to ultra-high-density deployments. Our approach integrates liquid cooling (direct-to-chip, immersion), rear-door heat exchangers, in-row cooling units, containment strategies, and heat rejection systems, coordinated with electrical power distribution to ensure thermal performance, energy efficiency, and operational resilience across diverse density profiles.

Enables scalable infrastructure for future expansion

Power Systems Analysis

Data Hall Planning & Cooling Strategy

We design integrated data hall layouts and cooling strategies that coordinate mechanical infrastructure with electrical power distribution to support the operational requirements of hyperscale, colocation and enterprise facilities. Our approach optimises airflow pathways, busway & containment strategies, equipment placement, and rack-level power delivery to ensure efficient thermal management, support diverse density requirements across the white space, and maintain operational reliability for both current deployments and future technology transitions.

Improves cooling efficiency and thermal performance

Maximises usable white space and equipment density

Reduces energy consumption and operational costs

Enhances overall system reliability and uptime

Structural & Building Engineering

Our structural engineering services integrate with building mission-critical systems to ensure facilities can accommodate heavy mechanical and electrical plant loads, support distributed equipment configurations, and enable future capacity expansion. Our approach coordinates structural design with mechanical plant room requirements, electrical equipment foundations, cable routing pathways, and seismic considerations where applicable, creating safe, robust and adaptable facilities that support the long-term operational demands of mission critical environments.

Supports heavy equipment and infrastructure loads

Enhances building durability and operational resilience

Enables flexible layouts and future expansion

Reduces structural risk and long-term maintenance issues

CFD Modelling & Thermal Performance Analysis

We utilise advanced Computational Fluid Dynamics (CFD) modelling to analyse airflow patterns, temperature distribution, and thermal performance across data hall environments and mechanical plant rooms. Our analysis validates cooling system designs, evaluates containment strategies, identifies potential hot spots or recirculation zones, and assesses the thermal impact of varying rack densities and equipment configurations, enabling optimisation of mechanical infrastructure and identification of potential thermal risks before construction or deployment begins.

Optimises cooling system performance

Identifies airflow and thermal inefficiencies early

Reduces energy consumption and cooling costs

Enhances reliability and equipment lifespan

BIM & Digital Design Coordination / Digital Twin & Asset Intelligence

We utilise Building Information Modelling (BIM) to coordinate multidisciplinary designs, detect clashes and streamline collaboration across project teams. Through advanced 3D modelling and virtual prototyping, we simulate complex, high-density data centre infrastructure environments to identify and resolve spatial conflicts, equipment access constraints, and constructability risks before construction begins, improving design accuracy, reducing site-based coordination issues and enabling more efficient project delivery. Our models can evolve into operational digital twins, providing ongoing asset intelligence and documentation that supports facility management throughout the operational lifecycle.

Improves coordination between engineering disciplines

Identifies design conflicts early through clash detection

Enhances project transparency and collaboration

Reduces construction risks and delays

Sustainability & Energy Modelling

We integrate sustainability and energy efficiency considerations into mission-critical facility design through advanced energy modelling, PUE optimisation analysis, and renewable energy integration strategies. Our approach evaluates electrical system efficiency, distribution losses, mechanical system performance (cooling plant efficiency, free cooling opportunities, and heat recovery), and renewable procurement options (on-site generation, microgrids, power purchase agreements, and grid decarbonisation pathways) to reduce carbon impact, support net zero objectives, and deliver high-performance, future-ready data centre facilities.

Improves energy efficiency and operational performance

Supports sustainability and net zero objectives

Reduces long-term operational costs

Enhances environmental performance and regulatory compliance
