Capability 04 / The Work Underneath

Built Below
Before It's
Built Above.

Every playground, pump track and trail we hand over is standing on work nobody photographs. Cut, fill, retain, drain, then finish the street around it. Get this wrong and the visible work fails within a year. We don't let that happen.

Timber bollards and retaining structure built into a Wellington slope by Outsiders Ltd

The unglamorous part

If the ground moves,
everything on it moves too.

Civil and groundworks is the part of the job that's finished before most people know we were there. It's the cut and fill that gets a site level enough to build on, the retaining that keeps a slope where it's supposed to stay, and the drainage that decides whether a space is usable in July or a mud pit until October.

We treat it the same way we treat the visible work: engineered properly, built for Wellington ground and Wellington weather, and signed off before the next trade starts on top of it. Get the groundworks right and the playground, the trail or the streetscape above it just works, season after season, without anyone thinking about what's underneath.

What's covered

Three disciplines.
One foundation.

Scoped and priced alongside the visible build, not bolted on after.

01

Earthworks and retaining

Cut, fill and engineered retaining that holds a Wellington slope where it needs to stay, load-rated for the structures built above it.

02

Drainage and services

Stormwater, subsoil drainage and the underground services a public space depends on, run before a single surface goes down.

03

Streetscapes

Kerbs, paving and the streetscape detailing that ties a project into the footpath and road it sits beside.

A maintained trail cut and drained across a steep green Wellington hillside

Where it actually gets tested

Steep, wet,
and unforgiving.

Wellington doesn't hand out flat, dry sites. Most of what we build sits on a slope, near the coast, or both, which means the groundworks have to do real work before the finish ever shows.

Steep Terrain

Access solutions and retaining that last. Retaining is engineered to the grade, not guessed at.

Wet and Wild

Drainage, stability and durability in all weathers. Drainage is designed in before anything is paved over it.
