Speaking on the advantages of this technique, H Raja Simha, Technical Advisor to Commissioner, BBMP, explained that this technique is cost-effective, makes optimum usage of open land and most importantly does not disturb the activities on the surface above.
“One-third of the road is utilised for parking vehicles. By providing multi-level basement parking more space can be created to make room for the growing vehicular population,” added Raja Simha, who invented this technique along with Prof B R Sreenivasa Murthy, Professor Emeritus, IISc.
In this technique, a land space is created of any desired depths under an open surface like roads, vacant land, parks without disturbing the movement of vehicles and people above. To create basement parking space, bullet beam jacking technique is adopted in which beams are inserted underground.
Following this mild steel plates are inserted between the flanges to create a platform for parking. In the same manner, this process can be extended in the longitudinal direction to create multiple levels.
On a public private partnership model, the BBMP is considering the construction of multi-level parking system in areas which have high density of vehicular movement. “We have identified a few areas in the City which requires additional parking space. Within a span of two to three months BBMP will commence the construction of the pilot project which will cost Rs 2,300 per square feet,” said K R Niranjan, BBMP Special Commissioner (project).
Apart from the basement parking system, the BBMP is also planning to construct skywalks with elevator facility at road junctions for safer pedestrian crossing. The BBMP has identified 365 roads specially around hospitals and schools across which skywalks will be constructed at a cost of Rs 1.5 crore each.
