Consultancy firm LEA Associates recommended L&T Hyderabad Metro Rail to take up longer span works at junctions going up to 34 metre or about 112 feet with segmental construction.
However, in cases where the length is more than 34 metre, such structures will have to be constructed on the site against pre-fabricated links and shifted for the project implementation.
This recommendation was made by LEA in its report based on a traffic study. The services of the consultant have been enlisted by the Metro project for traffic management solutions.
On-the-site bridge construction would be required at about 80 junctions. It has been proposed to provide temporary support for the elevated concreting deck. And after tying the steel reinforcement, concrete work will be handled in three stages. The support will be placed in a way that there will be about 50 feet gap which will allow smooth flow of traffic.
The metro project will have to construct about 80 flyovers over the 72 km stretch in busy road junctions without disrupting traffic.
Since the bridge construction at major junctions will take about 4-5 months, several junctions will be taken up simultaneously to save time, according to NVS Reddy, Managing Director of Hyderabad Metro Rail.
The design solutions given by the structural engineers of the concessionaire L&T have won appreciation from both Delhi Metro team and experts from Indian Railways.
