The preliminary market engagement notice was published on 7 May 2026, and expressions of interest are due by 15 May 2026. The project aims to identify hazardous trees, leaf-fall risks, and Ash Dieback, with the survey scheduled to be completed by the end of the current Control Period. The procurement is above the threshold and involves a contract valued at £579,000 net, extending from 30 September 2026 to 30 September 2028.

This tender presents notable opportunities for businesses involved in survey services, particularly those specialising in drone technology and environmental risk assessments. Companies able to efficiently conduct lineside surveys will be well-positioned to compete, especially small and medium enterprises (SMEs) and voluntary, community, and social enterprises (VCSEs), as the contract explicitly states suitability for these entities. Additionally, the regular submission of survey data every four weeks indicates ongoing collaboration with Network Rail, potentially leading to long-term partnerships and further opportunities in the future. This project allows involved businesses to enhance their portfolios with a prestigious project focused on innovation and sustainability in rail infrastructure management.

## Notice

The purpose of this project is to seek a Supplier to deliver a comprehensive Lineside Tree Survey across Northwest & Central Region - Central Route network. The survey covers all land where trees may impact railway operations, including Network Rail-owned land and adjacent lineside neighbour areas. The objective is to identify hazardous trees, leaf-fall risk, and Ash Dieback (ADB) presence, ensuring a robust understanding of vegetation-related risks across the route. Central Route network is to be surveyed by the end of the current Control Period, supporting a continuous inspection cycle. Survey outputs will form a detailed asset inventory for upload to Ellipse and any future Network Rail master asset register. Survey data shall be submitted at four-weekly intervals.
