## Description
Thames Water intends to establish a Framework Agreement to appoint suitably qualified suppliers to deliver site investigation surveys and associated deliverables across its operational area.

This Framework is intended to cover both infrastructure and non‑infrastructure projects, which may take place on Thames Water sites, private or public land, and/or within highways and road environments.
