Domes, shells, tunnels, cooling towers has now proved that the overall satisfaction can be achieved • The formwork design of Bahai - lotus temple, Delhi, was extremely difficult. It consumed about 5 and half years time, but the end results were extremely satisfactory. • The slipform method and Push-Launching operation used for construction of Konkan Railway’s highest bridge could complete the project on time and expected quality and budjet. • Use of System formwork shall be made as a ‘RULE’ • Preplanning is extremely important to get the ‘EXCELLENT’results. • A few components which are subjected to rusting need to Galvanized for long life. • The options like – Purchase, Hire, by-back etc are available with the system formwork manufacturers.
