Structural engineering for complex commercial, civil, infrastructure and architectural projects across New Zealand

Why Viden?

Owners and directors, Tim Day and Mark Patterson are both Chartered Professional Engineers who are closely involved in each project.

Viden is a small Christchurch-based consultancy, with a focus on delivering practical and efficient structural engineering. Our team have been involved in construction projects throughout Canterbury, the South Island and New Zealand since 2011.

We work with contractors, architects, councils, public sector organisations, developers and project managers to deliver projects from concept and detailed design through to construction.

We are proud to have been involved in many exciting projects such as the Christchurch Museum Redevelopment, Temporary Hauling Bridges for the Scott Base Redevelopment, modular classrooms throughout New Zealand, the Christchurch Metro Sports Facility, and the Ryman Northwood Retirement Village.

Testimonials

“Having delivered residential land developments for decades, constructing a bridge was a first for Suburban Estates. Viden guided us through the design and construction process with confidence and clarity.

Their technical expertise and prompt communication made the project straightforward from start to finish.

We're stoked with the final result.”

Suburban Estates

“Viden are our go to when it comes to structural engineering. We appreciate the direct and common-sense approach taken by the team.

We find the team very approachable and are happy to work through issues that arise during construction.

We would highly recommend using Viden for any structural engineering needs.”

BW Construction

“We worked alongside Tim and the team at Viden to deliver a large strengthening project for a mutual client.

This wasn’t just your standard strengthening project, it required being proactive and adaptable to achieve the works in the tight timeframe.

When problems arose, we worked together to offer smart solutions.”
