Description

This represents a flagship project to construct the first new strategic water resource, and corresponding pipeline, in the South East for decades. Construction work is anticipated to start on the Havant Thicket Reservoir Project (the "Project") in 2024, for completion by 2029. The Project is socially, economically and environmentally significant. It is the product of collaborative regional water planning particularly between Portsmouth Water and Southern Water, and forms a key step in increasing water resilience in the South East. This Contract Notice relates to the appointment of the main works contractor for main reservoir works and additional elements ("Main Reservoir Works (MRW+) Contract" or the "Contract"), as further described at Section II.2.4). The main works pipeline contract and framework agreement under the Project are the subject of a separate contract notice being published at or around the same time as this Contract Notice.

Interested organisations must complete and submit a completed Pre-Qualification Questionnaire by the specified closing date and time. Submissions cannot be uploaded after this return deadline.

Portsmouth Water reserves the right at any time to cease the procurement process and not award any contract or to award only part of the opportunities described in this Notice. If Portsmouth Water takes up this right, then it will not be responsible for or required to pay the expenses or losses, which may be incurred by any organisation or Tenderer resulting therefrom. Except for the Contract(if any), concluded with the successful Tenderer, nothing in the procurement process shall create a contract, whether express or implied, between Portsmouth Water and any Applicant or Tenderer. Portsmouth Water intends to select approximately 4-5 Applicants to invite to tender.
