Principal Engineer at COWI Oliver Stross commented: "The deck cross-section consists of a central steel spine supporting the 3.2-metre wide deck, enabling the majority of the steelwork to remain planar despite the bridge's complex geometry.
"The bridge's parapets reflect the reeds and rushes found along the banks of the canal. The team used 3D parametric modelling to develop the geometry definition, giving each parapet panel a unique pattern.
"We worked collaboratively with the steel fabricator, SH Structures, to ensure that the design was achievable within the project's budget; we developed several prototypes to test and refine the design, which is laser cut from 8mm thick weathering steel plate.
"We used careful detailing throughout the design to produce an understated structure that allows the parapets and activities on the waterway to take centre stage."
Designing for construction
"To meet the project's programme, optimising the design to enable efficient construction was a key consideration," adds Stross.
"The span lengths and deck weights were carefully controlled so that the deck could be fabricated off site before being assembled and lifted into place as one piece by contractor Land & Water using a 750-tonne crane. This approach minimised the disruption to marina works and the canal traffic."
The bridge is due to open to the public in summer 2019.
