Dhirubhai Ambani Knowledge City is a technology park located on the Thane-Belapur Road, Koparkhairane in Navi Mumbai, India. Spread over 56 hectares, it was completed in 2002. The city is named after the famous Indian industrialist Dhirubhai Ambani and is owned by the Reliance ADA Group and houses a 24 hour National Network Operations Centre (NNOC) along with more than 13,000 employees working primarily for Reliance Communications division.
This site was earlier owned by ICI and housed the first polyester staple fibre plant in India. Upon acquisition by Reliance, the site was renamed Terene Fibres India Pvt. Ltd (TFIPL). Production facilities at the plant had been moved out of this location by 2001.
The Campus is partially Wi-Fi enabled (I Block is a complete hot spot) with two HDFC Bank ATMs and one ICICI Bank ATM located therein. There is also an HDFC Bank branch located within the campus. A Reliance World outlet in the B Block enables employees and visitors to purchase handsets and avail other telephony services. Other than this, the campus has a huge artificial lake where migratory birds can be found at times. There are temples, fountains, medical facilities, parking lot for over 500 cars, and a helipad within the campus.
