'Ashray', a haven of modular molecules, is a Covid-19 hospital that has been planned by identifying the different user groups and segregating them into categories so as to provide maximum efficiency of functioning and comfort and safety to the users. The hospital has been designed such that it is flexible and the wards can be interconvertible so as to suit the influx of patients. The Covid ICU block, the General Covid block and the Non - Covid General block have been separated so as to balance the circulation and movement of various types of users and patients. The hospital has been also planned so as to provide scope for expansion in the future, and to also permit the conversion into a regular hospital. Steel has been used to permit modularity so as to ease the manufacturing and construction process, and enable the hospital to be constructed within 100 days, which is extremely essential in these times of dire need.
