Site Investigation Survey Framework

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. The Framework will enable Thames Water (and, where applicable, permitted person and including main contractors) to call off individual surveys and/or programmes of surveys on an as‑needed basis during the Framework term. 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. Thames Water reserves the right to refine the award criteria. Please note that that deadline for asking for access to the PSQ & submitting of the 5 March 2026.
