Abstract: MRTS (Mass Rapid Transit System) in India is a emerging concept and need of the hour. The construction technology is new to the country and there are many areas regarding construction and planning which needs to be understand. It is inevitable fact that gradually MRTS is going to be the backbone of every metropolitan city of the world with view of its development. Thus, from the infrastructure already constructed under this scheme of development we need to learn and devise the standard features and inputs that can be used for future planning and efficient construction. Metro Rail being the backbone of Delhi transportation system of Delhis infrastructure, it has many critical factor due to: a) Location of the MRTS route alignment b) Peculiar site, design and construction constraint c) Pressure on the government to commission the transport route lines to smoothen the transport requirement etc. c) To start use of the facility in order to generate revenue and pay back loans taken from international banks etc. Thus, through this paper an attempt has been made to understand the basic concepts regarding the construction methodology and technology primarily used in for “Underground Metro Construction” according to topography and site constraints. Various technological advancements have taken place and gradually new innovative and efficient variations have been introduced in the construction logic for underground metro stations. After establishing a generic understanding of the station peculiarities and construction procedures, information regarding two construction methodology of underground construction i.e. Cut and Cover (Bottom Up and Top Down) and Box Pushing Technique will be analyzed.
