Original Tender Description
Network Rail intends to establish a multi-lot framework for the delivery of geotechnical and civil engineering works across the Wales and Western Region. The framework will primarily support rock cutting remediation, earthwork drainage improvements, and burrowing management activities, delivered through a design-and-build approach. Suppliers will undertake investigation, design, construction, and handback activities, acting as Principal Contractor, and where applicable, Principal Designer
The Framework is divided into the following Lots:
• Lot 1 – Wales: Rock Cutting & Drainage
• Lot 2 – Western Rock Cutting and Drainage
Bidders may submit a tender for both Lot 1 or Lot 2; however, no bidder may be awarded more than one Lot under this Framework Agreement
The framework shall be delivered through a 3 year with a +1+1 option to extend. Based off the current indicative work bank the estimated contract value for Lot 1 is £40.8 million; Lot 2 is £36.8million.
.
Where projects are at an early stage of development, Network Rail may instruct suppliers to undertake surveys, investigations, feasibility studies, outline design and detailed design services. Following completion of these activities, the appointment to undertake surveys or design activities does not guarantee award of subsequent construction works.
Where an outline scope or performance requirement has already been established, Network Rail may instruct Suppliers on a Design and Build basis. In these circumstances, the Supplier shall be responsible for completing the design and delivering the construction works in accordance with the agreed scope and contractual requirements.
Where suitable designs already exist, including schemes previously developed under the Intelligent Client model, Network Rail may issue build-only instructions under the Framework
Complex and Bespoke Schemes - Mini Completion
Where a scheme is of a complex, bespoke or specialist nature and cannot reasonably be priced using the Schedule of Rates, Network Rail reserves the right to seek a standalone price from one or more Framework Suppliers or undertake a further competition between Framework Suppliers, where this is considered necessary to demonstrate value for money and achieve the optimal delivery outcome.

. Holding a valid Network Rail Principal Contractor Licence is a mandatory condition of participation in this procurement. To be invited to tender, suppliers must hold the licence at the date of the Participation Stage Questionnaire (PSQ) invitation. Suppliers that do not hold a valid Principal Contractor Licence at that time will not be invited to participate further in the procurement process.
This requirement is necessary due to the safety-critical nature of the works and the need to demonstrate the capability to undertake the Principal Contractor role within the operational railway environment from the outset of the contract.
