Aurecon assisted Gammon in developing an innovative design for the Global Switch Singapore Woodlands Data Centre.


Global Switch Woodlands Data Centre, Singapore

Innovating mechanical and electrical modular construction for the first time in Singapore

  • Aurecon’s role: Mechanical, electrical, hydraulics, fire engineering and acoustic services
  • Clients: D&C Contractor, Gammon for Global Switch

Aurecon uses prefabricated mechanical and electrical modular techniques for the first time in Singapore.

Designed to achieve Leadership in Energy and Environmental Design (LEED) Gold and Green Mark Platinum ratings, Global Switch Singapore Woodlands Data Centre was the first project in Singapore to use prefabricated mechanical, electrical and plumbing (MEP) modular techniques on a large scale.

With the objective of delivering a highly resilient data centre environment, Aurecon was contracted to provide mechanical and electrical engineering services to the design and construct (D&C) contractor, Gammon. This newest data centre in Singapore now allows scalable and flexible solutions supported by numerous connectivity options.

The 25 000 m² Woodlands Data Centre is strategically located in the north of the island and physically distanced from Global Switch’s existing Tai Seng Data Centre, to meet dual occupancy demand. It is spread over six levels and has been designed to exceed security requirements of local and international regulators.

Global Switch required high-quality standards as well as a tight timeframe. Aurecon assisted Gammon in developing an innovative design for the offsite modular construction of the mechanical and electrical systems, enabling Gammon to assemble more than 60 per cent of the MEP works off-site. This method of Design for Manufacturing Assembly (DfMA) off-site has multiple benefits including increased productivity, safety and quality.

An energy-efficient solution

To achieve an enhanced level of energy efficiency compared with other data centres in the Singapore market, the mechanical system provides a flexible and energy-efficient solution using six high-temperature chillers with direct expansion (DX) cooling of outside air to control humidity.

The resulting power usage effectiveness (PUE) of 1.34 makes the data centre one of the most energy efficient in Singapore’s tropical climate. By simplifying the chilled water systems, this resulted in significant savings for Gammon, and ultimately Global Switch.

The innovative electrical solution designed by Aurecon has not previously been implemented in Singapore. The electrical system provides high reliability and flexibility through an 18 x 2 MW diesel rotary uninterruptible power supply (DRUPS) connected to two high-voltage isolated parallel buses.

A distributed redundant low voltage distribution system provides a high level of flexibility for load distribution, and load growth to optimise the available capacity from the high voltage infrastructure.

Aurecon’s deep technical knowledge and collaborative approach were key drivers towards successful delivery of the project.

Aurecon utilised building information modelling (BIM) extensively throughout design development and construction. Regular laser scanning was used to verify the site installation and any variance updated within the BIM model as the construction progressed.

Aurecon also assisted in not only positioning the project to align with Singapore’s construction industry transformation efforts, but also boosting the industry’s confidence in adopting prefabricated MEP systems for higher productivity and quality.

Global Switch Singapore Woodlands was completed at the end of 2018, becoming the company’s 12th data centre in its portfolio, delivering best-in-class operational and environmental management processes. Aurecon has worked with Global Switch on data centres around the world, always with a focus on environmental sustainability.
