Infrastructure

Infrastructure projects shape communities and demand clear strategy, sound contract structures and effective delivery. Their scale and complexity require legal advice that is every bit as robust as the solutions being built.

At Arntzen Grette, we support public and private sector clients through every stage of the project lifecycle – from defining contract strategy and planning, to preparing contracts and tender documents, negotiations and execution. We also have substantial experience in dispute resolution, from negotiations to litigation before courts at all levels.

Our lawyers have advised on major developments involving roads, railways, metro and light rail, airports, hospitals, schools, water and wastewater facilities, and port infrastructure.

We are recognised for our expertise in project-specific contracts, risk allocation, partnering models, public procurement and construction law. We also understand the requirements of complex PPP structures and other delivery models. Working closely with project owners and contractors, we focus on securing progress, sustainable outcomes and sound project economics at every stage.

Substantial construction practice assisting private and state-owned clients with a range of matters, from advising on large disputes to assisting with contract negotiations. Regularly instructed by both domestic and international entities in energy projects and infrastructure developments, including procurement procedures and PPP matters.
