Network Rail has issued a prior information notice which is seeking contractors for £4 billion worth of contracts for a regional buildings and civil engineering framework for Control Period 6 (CP6) and beyond.
Covering Wales and the Western regions, the framework will run for a maximum time of eight years and is based on an initial three-year period.
If this is successful, there is scope to extend the framework for five one-year periods.
Split into six lots that cover the Western and Wales areas, the civil engineering framework will cover a whole host of work, including construction, project management, planning, renewals work, enhancement, and urgent interventions.
Network Rail’s tendering process has also declared that the maximum number of lots that can be awarded to one tenderer is five, ensuring that competition remains in the sector, and the work is spread out across a number of contractors and their supply chains.
It also ensures that not one contractor has too much power which could be to the detriment of the industry, as seen by the demise of Carillion.
The western lots of the regional buildings and civil engineering framework will be split into two sub lots based on value; for Wales, the lots will be split into four sub lots based on work types.
The first western sub lot is worth between £4 million to £30 million, covering renewals, enhancements and signalling, amongst other aspects; sub lot two is worth up to £4 million.
For the four sub lots of Wales, these are split into civils, metallic structures, geotechnical and SP&C and E&P work.
Organisations that are keen on winning these contracts are advised to express interest before the end of September. From then, the invitation to tender will come in February, with contracts expected to be awarded next October.
It is part of CP6 which will see the largest infrastructure expenditure commitment on the railways in history for the five-year period from 2019.
