About Us
Overview
Civil Infrastructure Services Group Pty Limited (CISG) is a specialist engineering-led construction company based in Western Sydney, focused on delivering certainty for Tier 1 and Tier 2 contractors on complex civil, building and rail infrastructure projects across Australia.
With over 25 years’ experience delivering major multi-billion-dollar programmes, we combine deep technical expertise with practical construction capability to provide innovative, safe and reliable solutions. Our strength lies in offering integrated design support, temporary works, staging and constructability engineering, paired with disciplined, self-performed delivery.
CISG excels in navigating the complexity of major projects, managing competing priorities and critical interfaces, and aligning teams and stakeholders to achieve time, cost and quality outcomes — without compromising on safety or delivery performance.
Certainty through experience
We are a specialised design-and-delivery contractor focused on complex civil, station and building infrastructure, where certainty, engineering rigour and seamless interface management determine project success.
Our integrated capability spans:
- Temporary works, staging and constructability engineering
- Civil, structural and station works
- Fit-out, mechanical and electrical coordination
- Systems integration
- Rail safety and access
- Management of critical interfaces
We combine design intelligence with self-performed construction, delivering practical solutions that reduce risk, compress schedule, and provide true cost certainty.
Our team is highly collaborative and agile, tailoring our services to the specific needs of each client and project — and providing a level of delivery assurance that few contractors can match.
Sustainability
CISG is committed to meaningful climate action, integrating sustainability into both our engineering processes and our delivery methods.
We work closely with clients to reduce embodied and operational carbon through smart design, optimised methodologies, and efficient construction practices — helping projects move confidently toward net-zero targets.
We have a proven track record of developing whole-of-life, cost-effective solutions that lower carbon emissions, reduce material waste, and improve asset performance. By engaging early and maintaining accountability through every stage of delivery, CISG ensures sustainability outcomes are realised in practice, not just in documentation.
Health and Safety
At CISG, health and safety is built into the core of how we design, plan and deliver. Our team leads with a mature, proactive understanding of critical risk management, underpinned by strong leadership, a high-performing culture and a systematic, engineering-based approach to safety.
We leverage decades of major-project experience across civil, rail, building and station environments — applying technical insight, practical constructability knowledge and proven field leadership to manage risks before they emerge on site.
Our culture is founded on integrity, ownership and accountability. Through genuine engagement, collaboration and consultation, we enhance the capability of our people and partners, ensuring safe, predictable and high-quality delivery on every project.
