The very first step, for Lavassan urban management, was how to define a project; an attempt showing architect responsibility which may not be perfect but would be considered as a forwarding step, in order to help urban issues.
Structures that not only sights have got used to it but have become an urban element; whereas you would not be able to avoid progress. They are being stealthy by installing advertisement banners and works of art such as either increase or decrease the price of tomato!
As far as all are consider, change may not be occurred suddenly but gradually: a plan which
- Does not cost high expenditure
- Does not transform the main structure
- Could be implement in general
Therefore, design was divided into 3 parts:
- Technical and executive revising on the prototype
- The last but not the least, removal of negative deduction of pedestrian bridge common structure, admit it and wearing a proper suit on it. A suit that does not remove the prototype and the structure not remove it.
A simple design inspired from swirling around the bridge deck: a comprehensible framework, slightly attraction in order to help people passing not only by but through it. That is the basic idea for the bridge.
One must have considered the limitations affecting on the final design: safe environment in the bridge, allowed height, the view from the inside out and vice versa and having the minimum height from the street. Afterwards, we had to get informed about implementing; an issue which have been playing a key role in architectural plans.
Noting that performing up in the air and swirling around the bridge axis, working on deck in the air was barely possible. Accordingly, we decided to prefabricate and move the structure to the location. Due to the traffic jam, each deck frame were considered as separate panels, up until being assembled after covering with composite sheets there. All led us able to plan a manufacturable detail in the location.
- Technical Notes
In the executive details, we used open section profiles, so that the bridge does not get into trouble facing humidity, corrosion, rain and snow. It also is resistant to speed up to 100 km wind. It should be noted that all the fittings are nuts and bolts. Regarding the width of composite sheets (which is 1.25 cm), the frame width has the minimum waste. Panels of each frame transferred and set down on the composite sheets, after being prefabricated and galvanized.
On the bridge deck, we implemented all demanded pickets while building, so that it may be covered by color homogeneously. It also helped us welding not in the location. Eventually, a pedestrian bridge in white, amongst green texture might absorb pedestrians using it.
