The site requirement
Retaining the road alignment and protecting native trees.
The retaining wall was required for a road to be made while protecting native trees. Drainage also ran underneath the road, making the road and drainage interfaces part of the site context.
Outwest supplied and installed the guardrail as part of this package, alongside the concrete sleeper retaining wall.
