Kapitol is proud to be the construction partner of choice for NEXTDC’s 72MW M2 data centre facility expansion in Tullamarine, Melbourne.
What we're building at NEXTDC M2 Tullamarine
We're helping build an extension to one of Australia's most important data centres, on Sharps Road in Tullamarine. A data centre is essentially a highly secure, purpose-built home for computers.
Almost everything people do online — streaming, banking, video calls, cloud storage, and increasingly artificial intelligence — runs on computer servers that have to live somewhere safe, cool, and powered around the clock. M2 is one of those places.
We are building three new two-storey buildings with associated services connections and infrastructure. These works are expected to take until the second quarter of 2027 to complete.
What is a data centre?
Think of it as critical infrastructure for the digital world, in the same way a power station or water treatment plant is critical infrastructure for the physical world.
M2 is located in Tullamarine near major transport and telecommunications infrastructure, which makes it an ideal spot to connect Victorian businesses, government, and households to the internet and cloud services quickly and reliably.
The facility is built to the highest international reliability standard in the industry (known as "Tier IV"), which means it's engineered so that services keep running even if individual pieces of equipment need maintenance or fail.
In practical terms: the apps and services people rely on stay online.
What is the M2 expansion (Stages 9-11)?
M2 has been built progressively over many years, stage by stage, rather than all at once.
The work we're delivering now adds significant new capacity to the existing site so it can support far more customers — including the growing demand for artificial intelligence, which needs a lot of computing power.
Once complete, M2 is a 120MW+ facility designed for cloud, AI and mission-critical workloads.
The new construction includes additional buildings to house the computer equipment ("data halls"), the electrical rooms that power them, and the supporting infrastructure that keeps everything running and cooled.
We understand construction activity at our site can bring noticeable change to the local area, and we recognise that this can be disruptive. Feedback from residents, businesses and other stakeholders is valuable in helping us identify issues early and improve how we manage the works.
If you have feedback, you can submit it via our contact form. All enquiries and complaints are taken seriously and you can expect a response within 7 days.
Backup generators are a standard requirement for critical infrastructure, providing emergency backup power during rare outages.
They are:
We recognise community interest in this area and aim to be transparent about how these systems are managed.
Data centres enable essential digital services that are relied on daily. As demand for online services and AI continues to grow, new infrastructure is required to support this increasing need.
No. The facility has been designed in close coordination with the electricity network to ensure sufficient capacity is available without impacting local supply.
Data centres operate under strict reliability requirements and include on-site backup systems to ensure continuity of service. These systems are separate from residential supply, meaning local homes and businesses are not impacted.
We understand that noise is one of the most important concerns for nearby residents. During construction, works are managed in line with approved hours and environmental requirements, with additional measures in place to minimise disruption wherever possible.
Once operational, the facility is designed with acoustic treatments and noise controls to ensure it operates within strict regulatory limits. We continue to monitor performance and respond promptly to any concerns raised by the community.
The current site location on Barrie Road is approximately 250 metres away from the closest households, helping to reduce impacts.
We acknowledge that construction activity can be disruptive and appreciate the community’s patience. To minimise impacts, we:
Our goal is to complete works efficiently while reducing disruption as much as possible.
Environmental performance is a key priority. Measures include:
We are committed to continuous improvement as technologies evolve.
We understand the importance of keeping the community informed and involved.
There are multiple ways to provide feedback:
All enquiries are logged and responded to, and feedback is considered as part of ongoing project delivery.
