## Summary

Seilwaith Amey Cymru / Amey Infrastructure Wales Limited, based in Pontypridd, is currently in the planning stage for a procurement process titled "Core Valley Lines - Cwmbach Drainage Renewal". The project falls under the services category and involves construction activities such as creating a new access chamber to an existing culvert, drainage system enhancements, and combating invasive species and waste. The focus is specifically on a site impacted by Invasive Non Native Species and fly-tipped wastes over a ~175m area. The project requires the successful supplier to have validated ConstructionLine Gold membership and possibly verified RISQS membership for railway-adjacent work. Key roles associated with the procurement at this point include planning and the identification of contractor requirements.

This tender offers significant business growth opportunities, particularly for companies specialising in drainage construction, ground-drainage work, and related services. Given the project’s complexity, it is best suited for businesses with relevant certifications and experience in large-scale infrastructure projects, especially those accustomed to working in challenging environmental conditions. The procurement is initiated through a tender process, making it an ideal opportunity for competitive firms to secure work on a critical infrastructure project in the Core Valley Lines area.

## Notice

Requirements are to construct a new access chamber to an existing culvert to allow future inspection and maintenance of said culvert from Transport for Wales's (TfW) land. The inspection chamber will also have an outfall to an overflow system during peak events. As part of the works, a channel will be cut from the inspection chamber to an existing culvert over a distance of ~175m, through an area impacted by Invasive Non Native Species and fly-tipped wastes. Should budget allow, this channel will be increased in area to increase attenuation locally during storm events.Further details and locations can be found in the attached documentation to this speculative publication.NOTE: To register your interest in this notice and obtain any additional information please visit the Sell2Wales Web Site at https://www.sell2wales.gov.wales/Search/Search_Switch.aspx?ID=144442.
