Summary of the contracting process

The "A483 Llandeilo and Ffairfach scheme" procurement process, initiated by the Llywodraeth Cymru / Welsh Government, is in the planning stage. The process involves infrastructure development in the construction and engineering sectors, aiming to progress a bypass scheme in the region of Llandeilo and Ffairfach, United Kingdom. The procurement is set under the Competitive Flexible Procedure as per the Procurement Act 2023, with upcoming key dates including the anticipated Tender Notice around the 17th August 2026. An engagement event on 27th October and a questionnaire deadline set for 10th November 2025 were part of preliminary market engagements to shape the Government's approach, focusing on topics like climate change and procurement strategy, alongside a signing of detailed groundwork insight at the tender stage.

This procurement opportunity presents significant potential for business expansion, especially for construction firms and multi-disciplinary consultancies experienced in project management and engineering services. With a value of £96 million gross, the project is an extensive one, drawing on various competencies such as construction management and engineering services. Firms that can navigate public sector procurement processes, particularly those able to demonstrate innovative environmental solutions and infrastructure expertise, are well-positioned to benefit from the planned works and subsequent contracts extending into 2032. Collaborative engagement, incentivisation mechanisms, and a focus on social value adherence provide additional avenues for contributing to project success and economic development within the region.
