The success of a joint operation in 1954 in salvaging five ships sunk in the Chao Phraya River led to a strong friendship between Dr. Chaijudh Karnasuta, a Thai, and Mr. Giorgio Berlingieri, an Italian. They together founded Italian-Thai Development Corporation Limited (ITD) on 15 August  with an initial registered capital of 2 million Baht. The company grew steadily and became publicly listed in the Stock Exchange of Thailand in 1994 with a registered capital of 2,500 million Baht and with the name changed to Italian-Thai Development Public Company Limited. Further growth to this date has brought the registered capital of the company up to 6,335.81 million Baht with 5,279.84 million Baht paid up.

After the sad passing of Mr. Giorgio Berlingieri in December 1981, ITD has been under an all-Thai management led by the Karnasuta family members together with a strong team of competent Thai managers and engineers.

The financial crisis starting in Thailand in 1997 dealt a big blow to almost all of the Thai companies. ITD was no exception and had to undergo a Business Rehabilitation process which was successfully carried out on 16 December 2002. That event turned out to be a foundation for a firmer growth of the company. At the year-end of 2003 ITD's turnover of that year was 18,330 million Baht making ITD the largest infrastructure construction company in Thailand and one of the largest in Southeast Asia . New contracts obtained in 2003 totalled 7,896 million Baht resulting in the total value of work in hand of 39,971 million Baht for that year.

ne of the important projects which ITD is proud of is the construction of the Suvarnabhumi International Airport , approximately 25 km east of Bangkok . The project had been continually under the development process for quite some time and ITD successfully completed it in 2006.

For several years up to now, ITD has successfully completed the construction of many mass transit projects, firstly the 23.5 km Bangkok Transit System (BTS). After that, ITD in joint venture with two japanese companies completed the construction of the 10.5 km northern part of underground Mass Rapid Transit (MRT) project which was about half the length of the whole project. The contract comprised construction of 10.5 km long, 5.7 m diameter, twin tunnels, 9 underground stations, and associate buildings (car parks, etc.). Other projects recently completed by ITD are the double-track railways from Huamark to Chachoengsao and from Bann Pachi to Lopburi, the Baan Uea Arthorn (low-cost housing) projects of the National Housing Authority, the tunnel for the underground high-voltage transmission line between Ladprao and Vibhavadi substations of the Metropolitan Electricity Authority, the Mae Moh Lignite Mining project, the Rama V Bridge, and the High-speed Railway project in Taiwan (a 27.3 km section).

In addition to the domestic market, ITD has expanded overseas to many countries such as India , Bangladesh , Cambodia , Lao PDR, Indonesia , Maldives , Myanmar , the Philippines , Madagascar , Taiwan , etc.
