Network Rail is seeking contractors for a £4bn framework of civils work on its Western and Wales route.
The control period 6 (CP6) framework will cover buildings and civil engineering with provision for signalling, power and, communications works.
It will include renewals, enhancements and reactive (urgent interventions) work as well as professional services, planning, construction and project management services.
The massive framework, which will cover the west of England and Wales for up to eight years, is divided into two lots: Western and Wales.
Western has then been split into two further lots based on the value of the projects. Meanwhile the Wales package is split into four lots based on work types.
The Western lots vary from less than £1M to up to £30M and will cover buildings and civil engineering with associated mechanical and electrical, signalling, power and telecoms works.
Lots on the Wales side of the framework include sea defences work, scour protection and masonry work, metallic structures, signalling, power and communications, plus earthworks and drainage work.
Prequalification questionnaires are due out on the 24 September with the information to tender due to be published on 18 February next year. The contracts are expected to be awarded in October next year.
The maximum number of lots to be awarded to any one bidder is five.
Yesterday Network Rail also launched its search for contractors for its £650M design services framework.
