How is the Hanhikivi 1 construction site managed?

Fennovoima manages the Hanhikivi 1 site by monitoring the overall operations to ensure that work is carried out precisely in accordance with the approved plans. The work and safety culture plays an important role.

Jouni Sipiläinen, Fennovoima’s Construction Director, how would you shortly describe the Hanhikivi 1 construction site?

The fenced-in construction site is nearly 100 hectares in size. The area has been divided into two sections, and Fennovoima’s share of the construction site is approximately 30 hectares. The remaining area of 70 hectares is the construction site of the plant supplier RAOS Project. Half of that area is what we call the construction site support area and the other half is the site of the power plant construction.

Currently, there are approximately 500 people working at the construction site. In the fall, the average daily number of workers was 450. The number of workers will increase considerably when the construction of the power plant begins: in a few years, there will be thousands of workers.

What is happening at the Hanhikivi 1 construction site right now?

We are preparing for the upcoming stages of the project, which at the construction site means specifically preparing for the construction of the power plant. The combined area of the temporary buildings on the Hanhikivi peninsula has already exceeded 100,000 square meters. Of course, the construction of supporting and auxiliary structures and infrastructure continues.

Openness is one of our most important principles.

At present, Fennovoima’s administrative building is being erected on the site. The excavation of the plant pit also continues. In the harbor, dredging is being carried out and a temporary dam is being built for the cooling water intake structures. In October, embedding concrete caissons in the backup water intake channel for a foundation began. In addition, ten storage halls were built next to the accommodation village and the canteen opened.

What is management at the Hanhikivi 1 construction site based on?

The construction site has designated management processes in place for cooperation with the plant supplier and subcontractors. For processes, there are also precise metrics, which we monitor. The requirements of the nuclear safety guidelines have naturally been taken into consideration in the management methods and systems.

Openness is one of our most important principles, and we communicate as much as possible. We also communicate the steps taken forward at the construction site to our own organization.

What is the operating culture like at the Hanhikivi 1 construction site?

The operating culture at the Hanhikivi 1 construction site is based on safety. In my opinion, we have succeeded very well in accomplishing it, and safety can never be emphasized too much. Above all, the safety culture is an attitude: at the construction site, everyone must know what they are doing. And if they don’t know, they should refrain from doing anything! The same absoluteness also applies to how we do things: everything is done in accordance with the plans and the requirements.

We have signed a site agreement with RAOS Project that applies to the entire construction site and all labor market organizations. This agreement must be complied with by everyone, including the subcontractors. The site agreement ensures that the terms and conditions of employment of all workers are in line with the applicable collective labor agreements. The construction site also has a joint employee representative and a joint industrial safety delegate.

How is occupational safety monitored and measured at the Hanhikivi 1 construction site?

In a proactive occupational safety culture, we identify and assess risks and their consequences.

In particular, we follow two indicators and their results: the MRV safety indicator that is used at civil engineering sites and the TR safety indicators that is used at building construction sites. In addition, we monitor the number of lost time injuries and near misses, among others.

Occupational safety is integrated in our daily work. Good management of occupational safety enables us to reduce absences due to illness and improve personnel well-being, which in turn help us increase productivity at the construction site.
