Balfour Beatty, Cavendish Nuclear JV wins £160m Sellafield contract
A Balfour Beatty and Cavendish Nuclear joint venture has won a £160m contract for the third phase of construction of a new silo maintenance facility for Sellafield Ltd.
Working in a 45:55 joint venture, Balfour Beatty and Cavendish Nuclear (the UK’s largest supplier of specialist services to the nuclear industry, and a unit of Babcock International) will deliver the facility which will be an integral part of Sellafield’s long-term waste retrieval hazard reduction programme.
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 and reducing hazard. 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 said it would bring a 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.
“Balfour Beatty has a strong heritage in the nuclear sector including our work across the existing fleet of UK nuclear power stations and our 35 year presence at Sellafield. We look forward to working with Cavendish Nuclear to deliver a facility that will support Sellafield Ltd’s overall waste retrieval and hazard reduction programme.“
Winvic tops out first hotel project in Milton Keynes
A roof covering programme is now underway which will be followed by floor and ceiling curtain walling, and extensive glazing on the 13th floor, which will contain a sky bar, restaurant and public exhibition space.
Work on envelope and cladding will continue with the 30m high, LED-lit satin finish stainless steel circle on the eastern façade completing the external design. The ‘sun’ design will be visible up the city’s Midsomer Boulevard, which was created to align with the sun on the longest day of the year.
Winvic is currently fitting-out the 261 bedrooms, which has included the sailing and positioning of off-site fabricated bathroom pods. Fit-out of other facilities within the hotel will also continue, such as the 12,000 sq ft flexible conference floor that comprises adaptable meeting spaces and an external terrace that has been designed to be high load bearing. The project is expected to be handed over in July 2022.
Mark Jones, Winvic’s Head of Multi-room, said: “We started on site just two weeks after the first 2020 lockdown was announced and despite the unprecedented challenges, our team have hit milestone after milestone on, or ahead, of schedule. I’d like to say a huge thank you to them. Reaching the highest point of any multi-room project is always worth celebrating, but this is a bit more special as it’s Winvic’s first hotel," he said.
Winvic recently lifted eight railway bridge beams into place over the A5, 2km north of M1 J18. It is one of three bridges that Winvic is constructing for Prologis at DIRFT III in Northamptonshire, as part of a £29 million contract to deliver a new Intermodal Rail Freight Terminal.
