We deliver Section 278 highway works in Harpenden and across Hertfordshire for signalisation or crossing works. Section 278 works are required when development impacts existing highways — new access, alterations or works on the public network. Clay ground affects trench sides, bedding compaction and invert level control during install. Highway authority lead times and traffic management approvals often govern programme more than construction duration.

The aim is to avoid assumptions that turn into avoidable delays once work is underway.

It is commonly used across new-builds, remedial programmes, and upgrades where technical choices affect programme, cost, and ongoing performance.

The goal is to resolve the underlying need with a practical method that fits the site and the intended outcome.

In practice, a clear plan from the start gives owners, facilities teams, and contractors a safer path to completion with fewer surprises during delivery.
