Louhintahiekka to build the first phase of Hermanninranta

The City of Helsinki has selected Louhintahiekka to carry out the first phase of construction in the Hermanninranta area. The total value of the turnkey contract is 26.5 million euros, and it is scheduled for completion in autumn 2027. The entire construction site will be implemented as a low-emission site.

Hermanninranta, located in central Helsinki, is a new residential district for approximately 5,500 inhabitants. The planning of this green and service-oriented neighborhood is rooted in ecological sustainability.

The contract awarded to Louhintahiekka includes the construction works for the first phase of Hermanninranta. This entails the construction of new streets, parks, and municipal infrastructure in an area currently used for port operations. Louhintahiekka will also build a significant portion of the shoreline wall around Verkkoneula and the Verkkosaari marina.

“The shoreline wall will be built using a pre-stressed drilled pile wall, which serves as the load-bearing structure for the reinforced concrete shoreline wall. As part of the contract, we will also construct 25,000 square meters of piled slabs, which will require the installation of a total of 71 kilometers of piles. The street structures and fill materials will amount to approximately 51,000 cubic meters,” says Aapo Lahtinen, CEO of Louhintahiekka.

According to Lahtinen, the project is extremely demanding overall, in addition to the tight schedule.

“Our core competencies include precise site management, mass transport and handling, and executing large-scale constructions. These skills will certainly be put to good use in the Hermanninranta project.”

The entire contract must be completed by 1 September 2027. According to the interim milestones, the school plot and its surroundings must be completed by 30 September 2026, and the Verkkoneula block by 30 May 2027.
