OUR APPROACH

ExCo brings a builder's mindset to every site — understanding how a decision on day one affects the trades that follow, communicating proactively, and treating every job as part of a larger programme of work.

That's the difference between a subcontractor who digs and one who thinks about what happens after the digging's done.

SERVICES

Full-service civil works

Real projects, real results

Three Canterbury sites, told by the people who worked with ExCo on them — a tight-radius residential build, unfavourable ground on a commercial site, and a piling job that held its schedule through a run of bad weather.

Two men are standing outdoors in a parking lot, engaged in conversation. One is wearing an orange safety vest and khaki pants, and the other is wearing a black jacket and jeans. The background features a building with large windows and leafless trees, indicating a late fall or winter setting.

"Hayden, Matt, and the boys are awesome to deal with — very approachable, good communication, and they made our job easy."

— James French, Cohesive Construction

"ExCo came up with another idea that probably saved me ten or fifteen thousand dollars, to be completely honest."
