About M2
Kapitol is proud to be the construction partner of choice for NEXTDC’s 60MW M2 data centre facility expansion with the completion of three additional stages and a further stage currently under construction.
Kapitol has worked in close collaboration with NEXTDC on the design and construction of each project. As a result we have been able to implement a number of VfM initiatives and introduce innovative building practices not previously used in data centre construction. These include novel, prefabricated, modular designs including precast core modules, and the use of super T bridge beam superstructures in the data halls, eliminating the need for columns and creating additional net lettable area (NLA). The use of the super T’s also allows for maximum efficiency and flexibility in the layout and arrangement of data racks.
Timeline and project information
The site is located on Barrie Road in Tullamarine. Kapitol is extending the existing M2 data centre facility for NEXTDC, supporting critical digital services such as healthcare, banking, cloud storage and online communications.
The M2 facility first opened in 2017, with eight stages completed up to 2024.
Current works underway are to complete stages 9 to 11, which will build out the site area, and take until the second quarter of 2027 to complete.
TIMELINE
Stages 9 to 11 – construction of three new two-storey buildings with associated services connections and infrastructure.
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.
NEXTDC is an exciting ASX 100-listed technology company enabling business transformation through innovative data centre outsourcing solutions, connectivity services and infrastructure management software.

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.
Operational noise is low level and primarily generated by cooling systems. The facility is designed to meet strict environmental noise limits and includes acoustic treatments to minimse impacts on nearby homes.
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.
Data centres are essential infrastructure that support the digital services we all rely on—such as cloud computing, banking, healthcare, and communication networks including those used by emergency services and air traffic control.
The facility has been designed in accordance with approved planning frameworks, including setbacks, landscaping, and built-form controls, to balance operational requirements with the surrounding environment.
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.
Sites are selected based on a combination of factors including:
These factors help ensure projects can operate efficiently while meeting planning requirements.
