Enabling contractor innovation and safeguarding quality

The island of Lidingö is part of the Stockholm inner archipelago and is connected to the main urban areas by a high-level highway bridge and a low-level bridge, which carries pedestrians, cyclists and a single tram line. As the 1925 low-level crossing became increasingly expensive to maintain, a new 700m SEK (£60m GBP) replacement crossing was planned in 2013. Greater provision was made for Active Travel and twin tram lines were included.

Knight Architects was appointed at the outset, developing alignment and Scheme Design options and achieving key approvals for the scheme, before being retained as client adviser for the Design & Build Tender and throughout the construction stage. A set of architectural design guidelines formed part of the tender, informing the contractor’s quality submissions while encouraging a cost-effective solution and giving room for construction innovation.

A Specimen Design was developed to demonstrate a solution to many design challenges, including a harmonious visual relationship with the nearby highway bridge and mitigation of the 750m length of the crossing to pedestrians. The restoration of a 1925 waiting shelter from the original bridge provided a destination as well as a place to rest. While a degree of design flexibility was allowed, areas of most sensitivity to bridge users were strictly defined, to ensure that the architecture and design quality was maintained throughout the detailed design and construction stages.

“This is a great day for the people of Lidingö and all travellers on the Lidingö tram, as you can now travel all the way from Gåshaga to Ropsten. We are very pleased with the effectiveness of the bridge: generous spaces for both bicycles and public transport, and built to budget and plan. We are now becoming part of Stockholm again, in a good way.”

– Daniel Källenfors, Mayor of Lidingö
