Four lanning project of REWA-MP/UP Border section of NH-7 for 89.3 km in the state of Madhya Pradesh was awarded to Vindhyachal Expressways Pvt Ltd, a Special Purpose Vehicle formed by JMC Projects India Ltd who appointed Dilip Buildcon Ltd (DBL) as contractor for this project. DBL entrusted Terre Armée in India to design and provide Reinforced Earth® system for wing walls of the Vehicular Underpasses.
During several discussions with DBL, Terre Armée in India realized that time was a prime concern for DBL. Therefore, Terre Armée in India proposed to build true abutment with Reinforced Earth® Technology (TechAbutment®) along with the wing walls for construction of VUPs.
Terre Armée in India made the technical proposal of construction of TechAbutment® for these VUPs. Terre Armée in India realized that Post Tensioned TechSlab, in this case, could optimize the thickness of the slab to 750mm, which would reduce the dead load on the TechAbutment®. Accordingly, value engineering was done with Freyssinet. It was also considered that the thin top slab also would reduce the length of both the approaches reducing the back fill quantity as well as the anti-crash barrier system. Freyssinet Menard India, a sister company of Terre Armée in India, was roped in for the design and construction of the PT slab in the project.
