Functional Dormitory Design

37This case study describes a design problem faced by the Indian Institute of Technology-Madras (IIT-Madras), a preeminent engineering institution in India, and Larsen & Toubro (L&T), one of India’s largest construction firms. Due to the rapidly increasing student population, IIT-Madras needs to construct more on-campus residences (hostels). However, because it is situated on the beautiful Guidny National Park, the university is restricted to 24% land use.

L&T recently completed a new group of high-rise hostels for IIT-Madras, but the older, sprawling-style hostels remain a popular choice among students. The two designs vary greatly in the areas of thermal comfort and social function. This case study explores how to design thermally comfortable and socially functional spaces while minimizing university land use.

Induction Welding Case Study

19For the year 2000, welding expenditures in the U.S manufacturing, mining, and construction industry were about $34 million.In order to test these welds in a non-destructive manner, nearly half a million radiographs are produced every year. Mr.R.J.Pardikar, Senior Deputy General Manager for the Quality/NDT division at the company, wanted a team at the Centre for Nondestructive Evaluation (CNDE) lab, Indian Institute of Technology (IIT), Madras to conduct a feasibility study of the possible Nondestructive testing methods applicable to the problem or develop new methodologies to identify defects in induction pressure welds.
