What we do

Our work spans bridges, boardwalks, marine and rail, roading, retaining structures, and complex concrete delivery – but what sets us apart is how we approach it.
We get involved early, think laterally, and always find a way to deliver. Whether it’s a constrained site, a technical scope, or a tight programme, we bring solutions not excuses. We make a plan, own it, and get it done. If it’s complex, then we have something to offer. If it's simple and has scale, let us show you how we can deliver efficient programmes to save you time and money.
We add value to a project through early engagement, developing design-and-build options and creating alternative construction methodologies.
Our projects include bridges, boardwalks, roading, marine structures, rail infrastructure, retaining walls, coastal works, precast concrete structures and waste water infrastructure.

What we do

We optimise designs and develop efficient methodologies through early contractor involvement, smart engineering, and virtual construction. Here’s the kind of work we’re known for:

Bridges and boardwalks

From delivering multi-span Super-T bridges to constructing timber boardwalks through wetlands. Projects like SH39 Mangaotama, Jubilee Bridge and Glen Innes to Tāmaki Drive show what we do best.

Marine and coastal structures

We deliver floating pontoons, jetties, seawalls, and complex piling in the Coastal Marine Area. See our work at Hobsonville, Waikowhai, and Seaside Park.

Rail infrastructure

We understand KiwiRail’s network and safety environment, and how to work effectively within it. We’ve delivered over, underand within KiwiRail’s networks. Parnell Underpass, Newmarket Level Crossing, and Huapai Footbridge are recent examples.

Retaining walls and structural systems

We’ve built everything from anchored King post walls to shotcrete and MSE systems in tight city environments – Wakefield St, AMETI, King’s School.

Precast and in-situ concrete

Our teams handle architectural, structural and heavy civil concrete. We’ve worked above live traffic, in rail corridors, and tidal zones. Projects include Point Resolution, Hobsonville and Mangatoetoe.

Roading, pavement, and surfacing

We deliver high-volume road and shared path upgrades, including subgrade, surfacing and drainage works – Loop Road, Purewa, Ellerslie, and CRL.

Key projects

Pedestrian Level Crossing Station Access Bridges

Oxcon is delivering three new station access bridges at Glen Innes, Takanini, and Te Mahia as part of Auckland Transport’s Pedestrian Level Crossing (PedLX) Tranche 2 programme. The works strengthen safety, accessibility, and network performance across Auckland’s rail system, providing fully accessible bridge connections between surrounding streets, station platforms, bus facilities, and shared paths. Started with an Early Contractor Involvement phase in which Oxcon worked closely with Auckland Transport, Beca and KiwiRail to shape the delivery methodology, refine staging, plan temporary works, and integrate the bridges into complex live rail and road environments. Construction is now underway across all three stations, with piling, substructures and approach works progressing concurrently.
