Specialist areas of expertise


RedJak have delivered large and small scale commercial projects, from 30 storey office towers to small tenancy fit out works. Regardless of the project size, our overriding principal is the same; to deliver a perfect working environment for our clients.


At RedJak we understand the unique challenges that face large scale retail operators. Retail facilities require strict program compliance and careful co-ordination with tenancy fit out works. Our project teams know what works for shopping centres, and they know how to deliver it on time.


The RedJak team has a depth of experience in constructing and commissioning more efficient data centre cooling systems (computer rooms).


The quality of our finish, and the reliability of our work, has seen a strong rise in repeat business from a number of prestigious high rise residential projects we did in Sydney and the ACT.
