Overview
This project won the prestigious ICE Small Project Award 2021. The ICE made the comments below.
“A critical upgrade on a main trunk road route that otherwise would have had a massive impact on society connectivity, requiring a 15-mile detour. The team dealt with unknown asset condition but focused on repair not replacement – a blueprint for reducing carbon in infrastructure. This was real “hands-on”
engineering in action.”
