Seamless project delivery, from start to finish.
Clients choose Calder Group because our integrated team manages every stage of project delivery, including design management, steel fabrication, precast manufacturing, and construction.
By bringing these capabilities together under one roof, we reduce project risk, minimise delays and provide greater certainty around cost, quality and programme.
Building trusted partnerships since 1980.
Our company has a proud history. Founded by Stephen Calder in Tapanui in 1980, Calder Group was established to serve the local rural community with quality buildings built to last.
Over 46 years we’ve steered successfully through major changes and have continued to innovate. Today, our ethos remains the same.
To provide expertise and a trusted partnership, and to successfully deliver, every time.
