Multiplex Tops Out Stage 2 of NextDC S3 Data Centre

19 October 2022

Premier global construction company Multiplex has reached a major milestone on the final stage of NEXTDC’s S3 data centre, ‘topping out’ the second stage of construction at 2 Broadcast Way, Artarmon on Sydney’s Lower North Shore.

Stage 2 of NEXTDC’s new S3 Sydney data centre comprises 12,000 square metres of data hall space and ancillary infrastructure on a site area of 12,513 square metres.

Designed by architects Greenbox, the building stands nine levels above ground (approximately 50 metres in height) and caters to the increasing demand for data storage and secure cloud systems as the use of digital services accelerates.

A significant employment generator to the local Sydney construction sector, the NEXTDC S3 Data Centre Project has employed a total of over 3090 workers to date.

Regional Managing Director of Multiplex NSW, David Ghannoum said the topping out of the final construction stage had been delivered with several separable portions located across the site, and amongst global uncertainty with procurement and supply chain challenges.

“We are pleased to reach this noteworthy milestone for NEXTDC’s landmark data centre, continuing our collaboration after the successful delivery of Stage 1 in July, and previously S2 Sydney in 2020,” said Mr. Ghannoum.

“It is a credit to the dedication and agility of our Multiplex team and our subcontractor partners.”

S3 Sydney is NEXTDC’s third and significantly largest data centre in Sydney. It directly interconnects to the existing S1 and S2 Sydney data centres and into NEXTDC’s broader national digital infrastructure platform.

It incorporates a variety of high-quality amenities including comfortable workspaces, a 100-space car park, and over 3,000 square metres of essential office space.

“S3 Sydney topping out completion highlights NEXTDC’s focus upon the effective collaboration and close-knit working relationships we develop with our strategic partners. Our successful relationship with Multiplex is a wonderful example of this. Together, we have demonstrated world class design, construction, and innovation capabilities at every stage of the S3 development,” said NEXTDC Chief Operating Officer Simon Cooper.

“This next generation facility has achieved Uptime Institute Tier IV design and construct certification and has been built to support our customers’ and partners’ need for data sovereignty, sustainability and best-in-class security,” said Mr. Cooper.

According to Multiplex, the hybrid scheme structure achieved program and cost benefits.

“The structure uses a combination of reinforced and post-tensioned concrete with structural steel K brace frame for lateral support in lieu of the more conventional concrete shear walls in turn saving significantly on time and cost,” explained Mr Ghannoum.

The NEXTDC S3 facility recently achieved the highly prestigious rating of Tier IV Certification from the Uptime Institute for Stage 1.

This classification is a globally recognised standard for certifying the 100% uptime guarantees for reliability, security, and performance to ensure data protection and business continuity. It also emphasises exemplary levels of resilience, providing the maximum amount of redundancy for power and cooling.

Construction of Stage 2 and all other separable portions of NEXTDC’s S3 Sydney data centre is on track for completion in April 2023.
