Construction of Fennovoima’s office buildings will proceed in the hands of Lehto Group

A contract worth some EUR 30 million has been signed. Construction of the administration building and the plant office is the most important project under Fennovoima’s scope of work.

In July, Fennovoima and Lehto Tilat Oy, a Lehto Group company, signed a contract on the design and construction of the administration building and plant office for the Hanhikivi 1 nuclear power plant.

The contract, which is worth some EUR 30 million, is based on a preliminary contract signed in 2018. The administration building is the most significant individual building under Fennovoima’s scope of work. Titan-2, the main contractor of the plant supplier RAOS Project, is responsible for the construction of the actual nuclear power plant and its auxiliary buildings, as well as for assembly of the subcontracting chain.

“Over the past year, we have developed design solutions for the offices together, and now we are preparing their construction,” says Juha Nurmi, Director from Fennovoima.

The final solutions used will be based on the client’s plans that have been fine-tuned with the contractor’s cost-efficient solutions.

“The development work was carried out in close cooperation with the client, and major cost benefits were achieved. By using the ‘design and implement’ model, Fennovoima has proven that it is genuinely willing to reform,” says Jaakko Heikkilä, Executive Vice President, Business Premises Service Area, from Lehto Group.

The construction schedule of the administration building and plant office will be finalized in late 2019 once the locations of the different parts of the Hanhikivi 1 nuclear power plant within the plant area have been confirmed. The construction will take approximately eighteen months. The goal is for the offices to be ready before the construction of the actual power plant starts.

Jaakko Heikkilä, Executive Vice President, Business Premises Service Area, from Lehto Group praises Fennovoima’s ability to renew itself, as the Hanhikivi 1 nuclear power plant administration building and plant office will be built using Lehto Groups “design and implement” model.

Offices for hundreds of employees

The five-story administration building and four-story plant office will be located in the plant area on the Hanhikivi peninsula. Each building will also include a basement and a ventilation machinery room on the roof. The total floor area of the administration building and the plant office will be approximately 18,000 square meters.

The administration building will serve as Fennovoima’s office during the construction and operation of the nuclear power plant. The plant office will include workspaces for the nuclear power plant’s operating personnel: operators, maintenance employees, and technical staff. During the construction phase of the nuclear power plant, the plant office will be used as the company’s site office.

At present, Fennovoima employs almost 400 people, of whom around 60 work at Pyhäjoki. Once the office buildings are complete, all the company’s operations and employees will be transferred to the Hanhikivi peninsula in stages. Most of the employees will move once the administration building is complete.
