Cavendish/Balfour Beatty JV wins third phase of Sellafield silo maintenance facility contract

26 June 2014

A £160 million contract for a silo maintenance facility at Sellafield has been won by a 45:55 Cavendish/Balfour Beatty JV.

This final phase of works follows the first two phases consisting of a £5.5 million preliminary design phase and £12.5 million detailed design and enabling works.

The new mechanical handling plant will support two existing waste silos with retrieving historic waste. At the heart of the heavily-reinforced concrete structure, which has a footprint of 0.5 hectares and will be 25 metres high, robotic installations will enable the Sellafield team to operate in a safe and controlled environment.

Balfour Beatty is bringing together its broad range of expertise to deliver the project including design, procurement, civil engineering, construction and mechanical and electrical capabilities. In addition, the company will provide fully integrated commissioning and pre- operations delivery strategy and will train Sellafield's employees in operating the facility.

A team of more than 100 engineers including nuclear specialists, civil and structural engineers and architectural technicians is currently using Building Information Modelling to create a full 4D design specification that dramatically reduces the construction programme. Work is scheduled to complete in autumn 2017, and the project will employ over 300 people at the height of construction.

Balfour Beatty Executive Chairman Steve Marshall said: "The UK infrastructure market includes significant opportunities for nuclear decommissioning and clean-up activities. Similarly, new nuclear build and the construction of new power generation projects will bring us an opportunity to deploy our extensive experience.
