Abstract: Building construction in India is carried out using conventional materials like concrete but it has limitation of span and size of components. As a result, large span areas that are essentially required for housing Electrical Extra High Voltage Gas Insulated Switchgears could not be covered by simple frames and required complex frame arrangements thereby increasing the required completion time. For design, steel has been the preferred material because of its ductile, strength, flexible, recyclability nature and low cost. With technology transfers, entrepreneurs had established steel centres where entire design to production is carried under one roof and the product is erected at site. These factories had given advantage of fabricating components either ahead or parallel to the civil works at site, thus saving time. Introducing the concept of Pre-Engineered building (PEB) into structural design resulted in design optimization and many advantages, including economy and easier fabrication when compared with the Conventional Steel building (CSB). PEB construction is widely gaining popularity over regular conventional buildings in India due to its sheer advantage in time saving. However, there is a challenge of proper and optimized design suiting to the Electrical Substation requirements such as pressurized atmospheric environment, Maintenance walkways, entry of electrical Bus ducts at various levels and locations. Any overlooking of the above may lead to overall failure of the electrical system. This would make it unique from the normal conventional PEB buildings done for Ware houses, Factories, etc. © 2021, Springer Nature Singapore Pte Ltd.
