Tollink Pakistan, a subsidiary of Tollink South Africa, needed BOT-Toll (Build, Operate and Transfer) collection facilities in Islamabad and chose for their project a canopy that stood out different in its form and architectural apparition. The preliminary design from Isbah Hassan & Associates was much appreciated. The structural engineering was done by Amjad Niazi Associates whereas the membrane engineering was done in China by Covertex. Mehatop FR 1000 was used as membrane: a PVC coated polyester fabric with a PVDF top coating on both sides. It has a weight of 1050g/m² and a tensile strength of 120KN/m – 110KN/m in warp and weft direction.
The most challenging part of the project was giving the required shape to the 200mm diameter pipe, with 6mm wall thickness. For this project a pipe bending machine and the allied heat process had to be made. Once the pipes were bent they were welded on the ground and the whole frame was lifted up to be placed on the vertical structural elements.
The very first project of tensile fabric structure in Pakistan got instant attention of the architects and was much appreciated.
