Adaptive solutions for Cape Town data centre expansion

Regular data centre upgrades are essential to meet the demand for energy efficiency, high density, and flexibility, with server lifespans around five years. Originally an industrial site, CPT 1 required significant structural upgrades to handle increased IT load and accommodate market needs. Our team was responsible for structural, civil, and fire engineering, drawing on global expertise and local insights. 

Located in a Zone 1 seismic area, CPT 1 required a thorough seismic compliance plan. A comprehensive design report detailed these measures to ensure safety and compliance. 

Responding to unforeseen on-site challenges 

Though initial drawings were complete, unexpected site conditions emerged once construction began. For example, structural deterioration required rapid reinforcement of floors and roof panels. Standing by the client, our team responded to these issues promptly, implementing on-the-fly solutions to prevent delays. 

Key actions included daily design management calls to maintain momentum and adaptability, structural reinforcements using carbon fiber to address stability concerns and the use of precast concrete, which allowed for rapid installation despite design modifications on-site. 

 

Achieving a zero-downtime expansion 

With the addition of three new data halls, CPT 1 expanded its IT load from 9MW to 15MW. The project included colocation data halls, infrastructure upgrades, and new systems such as generators and chillers. Despite being only 50 cm from operating areas, all work was carefully managed to maintain zero downtime for the existing facility, preserving client operations throughout the project. 

 

Outcome and completion

The project concluded in August 2024, adding a 6MW IT load and ensuring structural stability. Our solutions have positioned CPT 1 to continue reliable operations while meeting seismic safety and tenant requirements.
