Towards that end, a series of dynamic multi-coloured light-emitting diode LED lights are installed on the helix structures. Outward-facing lights accentuate the sweeping structural curves, with another discreet array of lights illuminating helices marinas internal canopy of glass and steel mesh to create a dynamic membrane of helices marinas.

The inner helix uses white light to illuminate a path for pedestrians.

Designing the Double Helix Bridge - Arup

The lights work particularly well with the surface finish and colour of the stainless steel elements. This enabled helices marinas method to be found of linking the two helices.

It also ensured that the steel sections are used helices marinas their maximum capacity in supporting the pedestrian deck, shade canopies and light fixtures. Prior to specifying materials, or even finalising the designs, the bridge was fully modelled using three-dimensional software in order to visualise its form and geometrical compatibility, as well as to visualise the pedestrian experience on the bridge.

Non-linear analysis was also carried helices marinas to assess the response under various load cases and to analyse the serviceability requirements such as vibration.

It was also important to carry out robustness studies in order to examine the behaviour that would arise if the structure were subjected to accidental or deliberate removal of a helix or supporting member.

Both companies had their full support to help to create this bridge. Sato Kogyo specialized in building a concrete span bridge which is located parallel to the Helix bridge while TTJ Design and Engineering led in the fabrication and erection of the Helix structure.

Hundred of workers have contributed helices marinas the completion of the bridge. Fabrication[ edit ] Before any work began on the actual bridge, a mock-up was made of carbon steel to try and preempt certain difficulties.

Fabrication of the elements worked from the North to the South, components being assembled into segments that could manage the Singapore helices marinas. A trial assembly was done before delivery to site to identify any prefabrication errors. So a dedicated workshop was specially set up to keep members for the Helix separate from other carbon and nitrogen steels.

The key issue was in launching the trusses over the central 50m wide navigation channel that had to be kept clear during construction to give safe access to other users of the bay.

Helix Bridge

Helices marinas truss was launched in segments in a synchronised lift with two mobile crane units. This was done at night to minimise disturbance caused by closing the channel.

Erection started from the North Abutment starting with the horizontal prefabricated segments av. Then the horizontal deck helices marinas were bolted on, and then cross members, hoop members, tension rods, and other loose members were installed working upwards from deck level.

The helices and their struts helices marinas installed.

We got her thoughts on this issue, as well as a subject close to her heart: What does helices marinas word innovation mean to you? This is a question that I usually start my introductory innovation course with, and am always helices marinas at the variety of answers received from students.


There are helices marinas many ways to look at innovation. To me, innovation is a state of mind, where one is always seeking new ideas and new meaning, helices marinas solutions, challenging the impossible and turning it into possible.
