Technology Services Partner Framework (TSPF)

The objective of the tender is to select service partners who are capable of providing services for each Lot, to enable SWS, at its election, to award work within a pool of pre-qualified service providers without the need to embark on a formal Procurement Act 23 process at individual project level. To facilitate this, the intention is that the successful bidders will be awarded a place on the Technology Services Partner Framework Agreement.

SWS will retain the right to compete work outside the pool of pre-qualified service providers (i.e. Procurement Act ‘23 process) where appropriate (e.g. where the pre-qualified service providers do not have the capability to deliver the services required by SWS or the price secured within the pool is not judged by SWS to be market competitive). Some of the key objectives of the framework include: • Establish a single route to market that covers requirements that Southern Water has for Technology Service Partners and resources • Support quick access to the right resources, in order to support Digital project objectives and deliver ongoing “run” activities • Modernise contracts • Increasing the use of outcome-based delivery and managed services • Deliver the optimum selection of Technology Services Partners • Support the Digital transformation agenda, including the best partners for future roadmap; updated and flexible engagement models incl. managed services and suppliers aligned to target operating model • Provide routes to market for Change Portfolio requirements A key objective of this procurement process for Southern Water is to deliver the optimum selection of Technology Services Partners.
