Summary of the contracting process

Severn Trent Water Limited is currently in the tender stage of its procurement process for the "Supply of Precast Concrete Tank Panels" project. The focus of the procurement, which falls under the industry category of concrete products, is rooted in the tangible goal of enhancing efficiencies in design time and construction processes for key assets across the United Kingdom. This particular tender is part of a larger Asset Management Plan (AMP8) initiative and invites participation with key dates including a tender period ending on 3rd November 2025 and an award period concluding on 19th January 2026. The procurement method employed is an open, competitive flexible procedure managed through a two-stage process involving a Prequalification Questionnaire followed by a Request for Proposal, aiming to shortlist potential suppliers efficiently.

This tender offers significant opportunities for businesses involved in concrete manufacturing and construction supply, particularly those specialising in precast concrete products and sustainable building solutions. Companies with a focus on innovation in construction materials, practical experience in modular construction, or efficiency-enhancing technologies in the water sector will find this project particularly appealing. The framework agreement's inclusion indicates the potential for long-term partnerships, whereby multiple types of precast concrete tank panels will be sourced for various projects, offering ongoing business opportunities to competitively positioned suppliers. With an estimated value of £6,000,000 and a contract commencement slated for 31st January 2026, this procurement presents a lucrative prospect for companies aiming to grow their footprint in the utilities sector.

Notice Title

Supply of Precast Concrete Tank Panels

Notice Description

Severn Trent Water are working on reducing design time, carbon efficiency and construction time for several key assets over the current Asset Management Plan (AMP8). Storage tanks have been identified as an asset used widely across the business, from storm tanks to distribution service reservoirs. Severn Trent Water have developed a Plug and Play modular precast concrete tank system that can be used in several applications which allow standardisation of assets, reduce costs and improve carbon efficiencies and now are looking to develop a supply chain to work with in supplying this asset, both directly as STW and also indirectly through the STW capital supply chain. The technical specification details the requirements for the supply of precast concrete panels for the Plug & Play tank solution. The tank solution is intended to be used across both potable drinking water assets and wastewater assets. It is expected that the split between clean water and wastewater will be unequal; most tank panels will be required for wastewater assets, demonstrated in the following volumes. The overall Framework will include a number of different product lines. These are: 1. Above ground square/rectangular tanks 2. Below ground square/rectangular tanks 3. Above ground circular tanks 4. Below ground circular tanks The first design completed, and included in theis tender document, will be for the product line "Above ground rectangular tanks 6m high". The designs for the remaining product lines are yet to be completed. As a result, Severn Trent intends to award the initial phase of the Pre-cast Concrete Framework to a single supplier. Only one supplier will be awarded the delivery of these initial phase and will be considered the primary supplier. As part of this tender process, Severn Trent will also select up to three secondary suppliers.

Key dates will be agreed in the Works Order between the client and the supplier. If the primary supplier is unable to meet the requirement (e.g., due to stock issues, lead time constraints, or quality concerns), the Secondary Supplier may be engaged and mobilised. If a secondary supplier is mobilised for a product line, then that secondary supplier will become a primary supplier for the product line (details further below). If there are multiple Primary Suppliers, then all will be contacted to establish ability to achieve project delivery requirements. All suppliers that can achieve the delivery program will be approached for project costs, with the lowest cost being allocated the order. ANY DEVIATION FROM THIS PROCEDURE MUST BE APPROVED BY THE CATEGORY MANAGER. Supplier Selection - New Product Lines For new requirements, all Framework (primary and secondary) suppliers will be contacted for the opportunity to put a cost and mobilisation time forward to become primary supplier for the new product line. Technical details will be shared with all Framework providers and details as to information required and submission timescales will be given to all to allow for Should the mobilisation time be within the Clients requirement, then lowest cost put forward will be chosen as the Primary Supplier for the new product line. The framework Schedule of Rates will be updated to reflect this new pricing arrangement. In the event that new product lines have efficiencies with current product lines already allocated to a Supplier. The utility reserves the right to directly allocate a production line to that supplier without approaching all framework suppliers. If a product line needs a new mould - it is a new product line. If an existing mould can be used then the design will be considered an existing product. Secondary Supplier Mobilisation on Existing Line In the event of the following: * Primary supplier(s) fail to meet KPIs * Primary supplier(s) fail to upscale to meet capacity * Secondary suppliers have a technological innovation giving them a product benefit * Benchmarking existing product line prices (i.e in the case of a same mould required for an additional product line) Then an additional primary supplier may be required/added to an existing product line following the process outlined in Section 2. New Product Lines. This will be done on a case by case basis."
