Breakthrough for Zelda on North East Link!

Tunnel Boring Machine (TBM) Zelda has achieved a rousing milestone with breakthrough into Manningham box at Bulleen - completing the excavation of the first of two three-lane tunnels. 👏

Launched in August 2024, Zelda has travelled over five kilometres to excavate the north-bound tunnel. Along the way, 2,576,166 tonnes of rock and dirt were excavated, and 22,060 tunnel segments installed. 🪨

Meanwhile, TBM Gillian is following closely behind with almost 90% of the south-bound tunnel excavated.

With TBMs operating 24 hours a day, this milestone speaks to the commitment, precision and safe practices of the crew working with Spark North East Link. 💪

Big build moment in the nation’s capital. 💪

The Canberra Metro Light Rail Stage 2A project team has reached a major milestone — completing the installation of a new watermain across the full width of Commonwealth Avenue in Canberra, using an ACT-first construction method.

What happened on site?

🔧 18‑metre watermain prefabricated above ground.

🏗️ Single 10.3‑tonne lift installed on each side of the corridor, removing the need for open trenches and underground boring under the road.

📐 Detailed planning for preparation works including lifting, welding, concrete encasement and backfilling.

🌍 Excavation of 1,000 tonnes of spoil and soil in the city centre.

This smarter approach reduced disruption and improved safety, while keeping the project moving.

The work supports the delivery of a wireless light rail extension that will modernise Canberra’s public transport system, alongside CIMIC Group partners Pacific Partnerships and UGL.

Progress you can see. Infrastructure built to last.🚊

A connected project on Sydney Metro West - Eastern Tunnelling Package (ETP). 🤜🤛

Delivered in joint venture with John Holland and Ghella, constructing TBM tunnels beneath Sydney Harbour and excavating Pyrmont and Hunter Street stations.

All ETP sites are now fully connected following a complex adit breakthrough at Hunter Street West shaft. This marks the shift from excavation to permanent structure.

Progress deep below the city includes:

🔩 Station cavern form having started the first arch crown pours
🧱 Lining works continuing through 380m of turnback tunnels beneath The Domain
♻️ Bulk excavation at Hunter Street East and low‑carbon concrete backfilling of temporary access tunnels
🏗️ First fully concreted arches in the 148m Pyrmont crossover cavern
⚙️ Cross passages complete from The Bays to Hunter Street and tunnel boring machines demobilised at Hunter Street.

Careful planning. Tight sequencing. Extraordinary teamwork.

Delivering health infrastructure involves more than building walls. It’s about creating spaces that support people.💙

At the Nepean Hospital redevelopment, work continues across key clinical and support areas, even within a live hospital environment.

What’s progressing on site:

🏥 Level 07 Palliative Care Balcony nearing completion

🩺 ICU fitout works continuing to take shape

🛠️ Careful coordination to minimise disruption

✅ Practical, high‑quality clinical spaces coming together

From detailed planning to on‑the‑ground delivery, our teams remain focused on solutions that work in real hospital settings.

Projects like Nepean reflect our experience in health infrastructure and our ability to keep momentum while navigating complexity - always with patients, families and frontline healthcare workers in mind. 👨‍⚕️👩‍⚕️
