THE Golden Jubilee Park coming up on Yamuna riverfront has been witnessing hectic activity since the past three months. Stacked across a portion of the park are what appear to be building blocks carved out of bamboo. The sound of carving machines rings loud as Ulrich Wallner, the man behind the project, watches the teams at work.
Director of Bambutec, Wallner flew in from Germany to train and work with teams from India. They are busy creating the components that will be fitted together to form bridges, machans and shelters — one in the shape of a flower — at the park.
Part of the Phase-I of Yamuna Riverfront Development project, under Delhi Development Authority (DDA), the Golden Jubilee Park will have an open air exhibition area, butterfly park, mythological park, wetlands and bamboo structures.
The park will be tucked between Old Railway Bridge and ITO, along a 189-hectare area. The first phase of the project is expected to be ready by next year.
"It's like Lego. All elements inter-lock with each other by using sustainable renewable resources. All the pre-fabricated components, mainly made of bamboo, are assembled on site. These structures — machans and bamboo shelters — will come up on helical piles. The piles will ensure that these structures are a little above the ground, in case the water level rises during rains,'' Wallner said.
A helical pile is an extendible deep foundation system with helical bearing plates welded to a central steel shaft. Load is transferred from the shaft to the soil through these bearing plates.
The workshops for Wallner's teams are made of bamboo, straw, clay, composite solution, limestone and plaster. According to DDA, this is the first time such technology is being used in India. No concrete has been used for these structures and piles make their foundations.
