Opportunity overview

This notice confirms the contract details of TfL's Infrastructure Improvement Framework for the delivery of multi-disciplinary infrastructure and construction projects including early contractor involvement, design and construction and build works. The framework will adopt an early contractor involvement and multi-stage contracting model enabling collaborative working with the framework contractors from early stage development of projects through design and into construction and completion. TfL has appointed three contractors to the framework and the framework contractors will be engaged through call-off contracts for project delivery. Projects will be allocated to framework contractors on a direct allocation basis, such allocation being monitored and re-visited throughout. Framework contractors will be allocated a workbank of projects in line with the equitable allocation principles of the framework and TfL may subsequently award call-off contracts. TfL has also reserved the right to award call-off contracts following a mini-competition procedure. TfL anticipates delivering a number of projects through the Infrastructure Improvement Framework including Elephant & Castle Station Capacity Upgrade, South Kensington Station Capacity Upgrade, Trams Rolling Stock Replacement Power and Depot and Infrastructure Works and TfL's Step Free Access programme. Additional projects may be added to the pipeline for delivery through the framework, throughout its duration. It is estimated that the total value of projects to be awarded through the framework will be between £500m - £700m.

Buyer Categories
The Framework may be used by Transport for London (TfL) and by any member or members of the TfL Group, or any combination of such parties, where such body is entitled to use the Framework and is acting as a contracting authority for the purposes of the Procurement Act 2023.
Description
In accordance with the framework allocation procedure, each framework contractor will be allocated a 'contractor workbank', containing the indicative allocation of projects for that contractor. The framework pipeline is divided into three equal workbanks having given consideration to value, risk, certainty, location and timing. The framework also allows for a mini-competition by exception in certain circumstances including where it is not possible to allocate a project consistently with the equitable allocation principles of the framework, where the allocation does not proceed as planned or where a call-off contract does not proceed to stage two. Where TfL wishes to enter into a call-off contract for an allocated project, it issues a request for proposal to the contractor, and upon agreement of the contractor's proposal proceeds to contract award and execution.
