Network Rail has gone to market with two frameworks worth a total of £4.65bn covering design and construction work across Control Period 6.
The rail client has opened bidding for its £4bn CP6 Western and Wales framework, while a prior information notice has been released for its £650m design services framework.
The £4bn deal will be split into two regional lots: one covering Network Rail’s Western route and one for its Wales lines.
Both frameworks are expected to last for an initial three years, with the option of a five-year extension based on performance.
The Western route will be divided into two sub-lots: one covering projects up to £4m, and another for jobs between £4m and £30m.
Both lots will feature building and civil engineering work as well as renewals, associated M&E, signalling, power and telecoms work.
The Welsh part of the framework will be split into four sub-lots: civil engineering renewals, enhancements and reactive schemes; geotechnical (earthworks and drainage) contracts; work on metallic structures; and signalling, power and communications work.
Prequalification questionnaires are due in for the week commencing 24 September, with ITTs being issued the week commencing 18 February 2019. Winners are expected to be announced in October 2019.
Network Rail has also published a prior information notice for its CP6 design services framework.
The £650m deal will be divided into 11 lots covering a range of elements including buildings and architecture, civils and structures, electrification and plant, geotechnical work, signalling and environmental jobs.
The framework is expected to run for the five years of CP6, with the potential to be extended to eight years.
Network Rail will run a supplier engagement day for the design services framework at the start of September.
In June the client launched the bidding for its £5bn track works framework, which is set to appoint three consortiums to carry out renewals and refurbishment works on tracks across CP6 and CP7.
The client is looking for three consortium outfits made up of contractors and designers to carry out works across North (Scotland routes), Central (the East Midlands plus the London to North-west / North-east routes) and the South (Western, Wales, Wessex, South-east and Anglia routes).
Last November, the UK government announced it would be investing £48bn into the rail network across CP6 – £10bn more than in CP5.
