Abstract: In our present world construction industries are the main ingredient for the development. So due to the rapid growth in construction industry, it is not possible to manage the project through conventional ways. Construction industry is having biggest role in economy of India. In recent times, if we look at the global economy and growth of population in India, land acquisition has became more difficult. To fulfill the need of shelter of this growing population and increasing industrialization, speedy construction is the necessity of time. Same time, due to inadequacy of land Vertical growth is preferable than Horizontal one. The high rise building construction consists of number of repetitive activities and also have same identical floors. The increase in duration of construction greatly affect the construction cost. Selection of best formwork system gives best result in cost saving. So that advanced formwork system helps in cost saving as reduction in slab cycle time. Conventional construction methods are not able to cope with the demand of infrastructural facilities with high degree of quality control & assurance. No doubt, conventional methods prove to be economical, but they fail in providing required number of dwellings in time; hence latest construction technologies by applying fast-track construction is the only remedy left to address this issue. The quality of construction mostly depends on the formwork used. This study aims to discuss and evaluate the various formwork systems available, and to show their impact on project duration, cost, quality, cycle-time, number of repetitions, labour requirements. Through literature review, data about various formwork systems available are collected. The current practices in Amravati region are known from various stakeholders through a questionnaire survey and case studies. Data analysis will be done using the data collected from the literature review and the questionnaire survey. The data were analyzed using Relative Importance Index (RII).Ranking of factors were done on the basis of RII and ranking them as per their degree of importance using Relative importance index method. The top 5 factors responsible for adopting the modern formwork system in construction projects, are High initial cost, Advanced Training Session, Lack of awareness, Suitability for mass housing project, Design flexibility.
