Review Paper on Precast and Cast in Situ for Metro Project | Original Article

ABSTRACT:

Arguably the most dramatic recent development of urban infrastructure is the introduction of the subway as a public transport system. In addition to being the main means of transportation, the subway has contributed significantly to reducing pollution and improving the quality of life of its citizens. The vehicle population in urban areas of India is rapidly increasing by While rapidly growing and expanding cities demand more urbanization and housing, new residential colonies and large commercial facilities are rapidly emerging, all integrated with public transport. need to do it. For civil engineers, metro projects have provided a great opportunity to develop skills and seek innovative solutions to the difficult problems inherent in large structures in the urban environment. Key design decisions determine the success of the project in terms of construction speed and quality, environmental impact and structural aesthetic appeal, and cost and economics. This paper describes some of the challenges faced by viaduct structures and how they were overcome in Indian metro structures through the use of precast concrete construction techniques.
