The company, whose landmark projects include the New Parliament Building in New Delhi and Atul Setu in Mumbai, derives above 20% of its projects from Tata Group companies such as Tata Consultancy Services, Tata Power, Indian Hotels, Tata Steel and Tata Electronics. The share, Pai said, has gone up from about 8% two years ago and can be attributed to the group’s significant investments in various sectors, including campuses, hotels and transmission lines.
