Bangalore International Airport, Bangalore, India
India’s first private International Airport is coming up in Bangalore and major portion of the work including construction of the Terminal Building is under way. The Terminal Building will have an S-shaped roof. This was to be constructed from finished precast concrete which in turn called for specially designed Formwork. Pranav was preferred for fabrication of this critical Roof Mould which is 7 m x 24 m long. Each mould segment is made up of ‘S’ shaped steel soffit of 24 m supported by truss. The fabrication tolerance allowed was 0 mm for matching surfaces of shutters. Each mould in fully assembled condition weighs about 147 tonnes and is designed to take up to 50 repetitions.
Nuclear Power Corporation Of India (NPCIL), Kudunkulam, India
For the 6 m high columns and wall for the reactor building at Kudankulam, Kerla a specialized formwork was required. The reactor building was to have a wall with a diaphragm, which permitted no tie-rods in the construction system. This special construction was to be cast in three stages and at high speed. Pranav designed a composite construction system with a suitable back-up frame. The system lent itself to very fast dismantling using a lift and shift system with the help of a crane. As a result, all requirements of the project especially casting speed requirements were comfortably achieved.
