Foundation Construction Experts at SSAB’s Steel Pile Day in Helsinki

The annual SSAB Steel Pile Day, held on January 18, 2018 in Helsinki, brought together about 350 contractors, designers, equipment manufacturers and representatives of authorities to find out more about SSAB’s products, infrastructure development, customer references and industrial outlook.

The event was kicked off by Kari Väliaho, General manager, Tubular Products at SSAB Europe, who challenged the participants to provide SSAB with feedback regarding product features, design solutions and other potential future needs.

Tampere piling sites providing ample examples

Downtown Tampere is being revitalized and redeveloped to further condense the urban infrastructure. There are several on-going projects, including the construction of a multi-purpose arena, which Head of Municipal Engineering Planning Unit, Jori Lehtokangas, discussed during the Steel Pile Day. He also mentioned the ongoing tramway project and the urban area of Hiedanranta, which is a testing platform for new technologies and methods, including earthworks.

Ossi Hakanen of Suomen Teräspaalutus Oy highlighted the use of drill piles at the Ranta-Tampella site.

Foundation reinforcement increases load bearing

Various methods have been carried out to reinforce foundations in Turku, and Reino Heikinheimo/Ramboll Finland Oy shared their experiences of these at the event.

Business Area Manager Jari Mara also showcased reinforcement sites from last year, featuring SSAB’s RR and RD piles.

“The Westpro Portus project involved the construction of a 14-floor building at Verkkosaari, Helsinki. Almost two kilometers of SSAB’s RD600/18 and RD700/18 drill piles were used in the foundations of the building,” said Manish Jaiswal of Sipti Oy.

Examples of steel piling from pier sites completed last year included the Naantali pier project, were beam lengths ranged from 35 to 56 meters. These examples were presented by Esa Kunnassaari of Terramare Oy.

Experiences from RD pile wall and piling sites

Pasi Mäkinen/Skanska Infra Oy and Petteri Kronqvist/Sitowise discussed the design and implementation of the RD pile wall at the K6 building site in Helsinki. Close collaboration between the designer and the contractor produced new, innovative solutions.

SSAB’s Piet van Breukelen described the implementation of the Peterhead port RD pile wall in Scotland.

Raimo Isopahkala/Niskasen Maansiirto Oy shared news of wind farm piling projects that had been running smoothly in Northern Sweden and Haapajärvi, Finland.

Collaboration with academic institutions

The Steel Pile Day also featured students, who had completed their theses for SSAB. Niko Korhonen had studied the traction capacity of a grooved anchor pile, Samuli Laatinen studied the structural engineering of steel pile wall support, while Antti Ahonen studied the suitability and design of steel fiber reinforced concrete in composite structure columns and piles.
