What is Segment Casting?
The segment is a crucial component of the Metro rail, as it acts as a base for rail track. Each segment is cast next to the previous segment in a special adjustable casting machine. This ensures that the interface between the two segments matches exactly when erected. Each successive segment is then cast next to the previous one. It is a sort of a bridge built in short sections (called segments), i.e., one piece at a time. A precast segment is constructed from pre-stressed concrete and the final form of the structure is then positioned where it has to be used.
The Pune Metro line III is a ~23 Km elevated Metro rail project connecting the IT hub of Hinjawadi to the Central business district of Shivajinagar. It is a Public Private Partnership (PPP) project awarded by the Pune Metropolitan Region Development Authority (PMRDA) to a consortium consisting of Tata Group’s TRIL Urban Transport Private Limited (TUTPL) and Siemens Project Ventures GmbH. The Project would be developed & operated on Design, build, finance, operate & transfer (DBFOT) basis by a special purpose vehicle (SPV), Pune IT City Metro Rail Limited or PITCMRL for a Concession Period of 35 years including the construction period.
