Henderson Compressor Station, Auckland.
This project is a prime example for showcasing Warner Constructions’ capabilities to undertake and execute multi-discipline civil and mechanical contracts in-house.
Warner’s has the inventory to carry out projects from conceptual to installation. Their skillset and proven track record have been refined to a very high standard with decades of engineering expertise and knowledge.
