## Summary

Transport Scotland, an agency of the Scottish Government, has completed a significant public procurement process concerning the "A9 Dualling: Tay Crossing to Ballinluig" project. This transport infrastructure endeavour involved widening approximately 5 miles of single carriageway to dual carriageway, while incorporating environmental considerations such as upgrades to side roads, junction construction, and the provision of new overbridge and underbridge structures. Located in central Scotland, north of the Jubilee Bridge over the river Tay, the scope of works aimed to enhance road safety, encourage active travel, and improve integration with public transport facilities. The procurement process adopted was a selective competitive dialogue, culminating in the award of the contract to Wills Bros Civil Engineering Ltd. The contract was signed on 31 July 2025, with an award value of approximately £152.7 million.

This tender presents substantial opportunities for businesses engaged in civil engineering, road construction, and environmental management. With the demand for expertise in areas such as road dual-laning, bridge construction, and sustainable drainage systems, the project aligns with businesses skilled in large-scale infrastructure development and environmental accommodations. Additionally, firms with a focus on integrating community benefits and delivering high-quality infrastructure could leverage similar contracts to expand their portfolio and client base. The project's setup, overseen by Transport Scotland on behalf of the Scottish Ministers, emphasises the ongoing potential for organizations proficient in collaboration with public sector contracts within the framework established by the Public Contracts (Scotland) Regulations 2015.
