## Description
Network Rail has carried out a procurement exercise to award the CP7 Southern Integrated Delivery (SID) agreement to deliver our Control Period 7 (CP7) and potentially CP8 renewals portfolio.
The SID will be a fully integrated team based on 'Project 13' principles comprising all categories of railway assets: Signalling, Track, Buildings & Civils (B&C), Electrification and Plant (E&P) and Minor Works. The scope includes the following items: development, design, manufacture, supply, installation, integration, testing and commissioning of the Southern renewals work bank.
These works will be undertaken on Kent, Sussex and Wessex routes, and will primarily be focused on the delivery of the renewals portfolio, however options will be included to enable enhancements also to be delivered, subject to capacity and where the SID is considered the optimum procurement route.
This notice covers the appointment of the Signalling (Lot 3) and Track (Lot 4) lots, where all appointed Business Partners within the SID have initially signed into a development phase agreement, scheduled from February 2023 to April 2024. The main SID agreement will be 10 years in duration (April 2024 -March 2034) and will commence in CP7 with the inclusion of a break clause prior to the commencement of CP8.
