A sustainable bridge that’s built to last, blends in harmoniously with its natural surroundings, and offers a solution to the triple constraints of time, quality and cost. This is what the City of Vantaa was looking for when it commissioned a footbridge for a national park at Lake Kuusijärvi, just north of Helsinki in Finland.
The fabrication and installation of the steel structures for this weathering steel bridge was done by Normek, a leading steel building construction and façade solutions company in Finland. As a specialist in the design, engineering, construction and on-site installation of steel structures for bridges and buildings, it brought its experience in other weathering steel bridges to the project. The delivery included steel girders, center columns and railings, all made in weathering steel.
Sami Torvi, project engineer at Normek, juggled time schedules, material purchases, manufacturing plans and quality documents for the project. He emphasizes the need to take a flexible approach to manufacturing:
“No two bridges are alike,” Torvi says. “We’ve got to be very flexible in our manufacturing processes because it’s very unlikely that we will manufacture two similar bridges. Every product is unique, and we need to think carefully all the way from material purchase through to final installation.”
