UK4 - Tender Notice
Summary of the contracting process

The procurement process is being conducted by Thames Water Utilities Limited, a private utility company based in Reading, UK. They are seeking suppliers for their "Site Investigation Survey Framework," which involves both infrastructure and non-infrastructure projects across various UK regions. The tender has been updated with a new submission deadline of 12 March 2026, 10:00 am, with expressions of interest required by this date. The active tender is in the selective stage with a competitive, flexible procedure and is split into four primary lots focused on different types of surveys, such as above ground, below ground, and multidisciplinary approaches. The total estimated value of the framework agreement is £176 million GBP. The contract period is set to begin on 30 June 2026, potentially lasting until 30 March 2034, considering possible extensions.

This tender offers significant opportunities for businesses specialising in surveying, engineering, and construction services, particularly those with capabilities in geotechnical engineering and GPS positioning systems. With the framework divided into lots, small to medium-sized enterprises (SMEs) have the potential to compete effectively, either individually or through partnerships, to provide comprehensive solutions. Businesses that can offer competitive and innovative survey methodologies could benefit greatly from securing a position in this framework, gaining access to multiple call-off contracts throughout the contract term. The flexible procurement process allows for iterative engagement, enhancing the chances for bidders who excel in technical quality and commercial competitiveness.
