Bridges by VFT method in Poland: state-of-the-art - Economical Bridge Solutions based on Innovative Composite Dowels and Integrated Abutments - page 110

Starting in June 2011, the 137 beams were rolled to final lengths between (25 m and 41
m) at the mill of Differdange, Luxembourg. All beams belong to the slender HL1100 family
(steel: HISTAR460), which was developed for bridge applications. Afterwards the beams
were cambered and the necessary beam finishing (welding of reinforcing plates below lower
flanges at intermediate piers, end plates, headed studs and painting) was done directly on
the steel plant. Thanks to this effective steelwork purchasing, the first fully finished steel
girders for the WD7 viaduct were delivered in Gdansk already in August 2011 (by train up
to Gdansk, and by truck to the construction site). Due to the relevant size of the bridges, the
contractor decided to pour the prefabricated concrete slab in a yard near to the final site.
Maximal element weight could reach 50 tons.
