Supply & Install of Modular Treatment Equipment: Preliminary, Primary Filtration and Fixed Film Biological Systems
Notice Description
This tender process is for the provision of Supply & Install of Modular Treatment Equipment: Fixed-Film Biological, Preliminary and Primary Filtration Systems. A summary of the scope across all Lots forming part of this tender is stated below. The Modular Treatment framework will consist of suppliers who have the ability to design, supply & install containerised assets on a flatbed vehicle as a standalone solution either be removed via roll on/roll off functionality or craneage. This framework will also consider semi modular assets which are assembled/installed by the asset supplier and involve greater civil complexity due to these assets requiring partial burying, but typically without the requirement for additional shuttering that's associated with traditional concrete assets. These assets will either be purchased by the Utilities directly and the novated or free issued to the Utilities Capital Construction supply chain partners.

Responses will be evaluated against the criteria set out in the PQQ briefing pack, and the six highest-scoring suppliers in each lot will be shortlisted to participate in the next stage of the procurement process. Shortlisted bidders will then be invited to submit a detailed proposal in response to the Request for Proposal (RFP). The procurement process will then comprise a number of subsequent evaluation, scoring and moderation stages, as detailed within the RFP briefing pack. As an initial assessment, bidders' responses to the proposed terms and conditions will be reviewed before any other part of the submission. These stages may include proposal evaluation, supplier clarification discussions, presentations, site visits and commercial negotiations, where deemed appropriate by Severn Trent. Severn Trent reserves the right to amend, combine or omit stages as set out in the RFP briefing pack and in accordance with the Competitive Flexible Procedure."
