## Summary

The Welsh Government is planning a procurement process for the A483 Llandeilo and Ffairfach scheme, focused on construction work and engineering services, as part of its National Transport Delivery Plan. The project is positioned in Cardiff, with a preliminary market engagement phase ongoing, with a key in-person event scheduled for 27th October 2025 at the Parkgate Hotel in Cardiff. The planning stage invites potential bidders to complete a questionnaire by 10th November 2025, which will inform the design of delivery models and procurement strategy. A future notice for the tender is expected by 9th February 2026, with the contracted work planned to start on 1st July 2026 and conclude by 1st February 2031.

This procurement initiative presents an attractive opportunity for businesses in the construction and engineering sectors, especially multi-disciplinary consultants and works contractors. The Welsh Government's plan includes developing delivery and contracting models that could stimulate business growth. Given the project's scale and scope, it invites participation from SMEs and organisations capable of providing comprehensive construction and project management services. Engaging in this procurement could benefit businesses looking to establish long-term partnerships and potentially influence the project's strategic direction through the current engagement process.

## Notice

The National Transport Delivery plan, published in February 2023, reaffirmed Welsh Government's commitment to continue work on options to progress the Llandeilo bypass scheme. A preferred route for the new road has also been identified:- https://www.gov.wales/a483-llandeilo-and-ffairfach-preferred-route Delivery of the scheme will require the input of both multi-disciplinary consultants and works Contractors. WG is currently in the process of developing both its delivery model and contracting model for these inputs. This market engagement exercise is being conducted to help inform the design of these delivery and contracting models, as well as the WG's procurement strategy more generally.

### Planning Information

The engagement will consist of two parts:
Firstly, an in-person event on Monday 27th October at the Parkgate Hotel Westgate St, Cardiff CF10 1DA at 10:30am. The purpose of the event is not to inform the design of the delivery and contracting models, or the WG’s procurement strategy per se; rather it is to give potential bidders an overview of the project. The event is open to potential bidders, if you wish to register your attendance, please email A483LlandeiloandFfairfach@arcadis.com
To attend the event in person pre-registration is required, with a maximum number of 2 attendees per organisation. Upon registering your attendance, you will receive a copy of an invitation to complete a questionnaire to inform the design of the delivery and contracting models, and the Welsh Government’s procurement strategy. This questionnaire invites potential bidders to provide their views on a range of issues, including, procurement strategy, climate change, key commercial terms, project scope and potential barriers to bidding. 
If you are unable to attend the event and wish to share your views via our questionnaire please request a copy of the questionnaire via our mailbox A483LlandeiloandFfairfach@arcadis.com
Potential bidders are requested to return their completed questionnaires by 12:00pm (midday) Monday 10th November 2025 to the following address: A483LlandeiloandFfairfach@arcadis.com
Depending on the outcome of this engagement process it is possible that Welsh Government may consider changes to the future procurement.
