Great British Energy – Nuclear (GBE-N) has outlined plans for an early works contract worth up to £1.1bn as part of its small modular reactor (SMR) programme.

The government-owned nuclear developer said the package would cover civil engineering, infrastructure, buildings, mechanical and electrical work and earthworks at the Wylfa site in Anglesey, north Wales.

The contract has an indicative value of £730m-£1.1bn and is expected to run from June 2028 until June 2034, GBE-N said in a preliminary market engagement notice.

It also included an option to extend the contract until June 2037.

The client said it had previously considered splitting the work into two packages but ultimately decided to combine them to reduce interfaces between contractors.

The successful supplier will take responsibility for design from RIBA stage four and delivery of site-enabling works.

The successful supplier will take responsibility for design from RIBA stage four and delivery of site-enabling works.

Work will include species relocation, remediation, site clearance, site establishment, construction utilities, drainage and haul roads supporting bulk earthworks.

The works are intended to establish ground levels, provide construction access and create the physical platform required for later phases.

GBE-N said the programme will cover planning, licensing, design and construction needed before its technology partner installs and commissions SMR technology.
