建設データ Company Profile

The number one membership rate for major general contractors and local construction companies. You can easily see the latest bidding status of each company. This is a site that covers and provides bidding information for 10 prefectures in the Kanto and Koshinetsu regions.

In March 1995, we launched Japan's first commercial online database service for the construction industry, "KDnet," capturing the trend towards electronic information represented by construction CALS/EC. We played a pioneering role in the industry by building and selling a database of newspaper information. In 1998, we were also highlighted in the Diet as a leader in this field, taking on the role of promoting the digitization of government administration. Starting in 1999, we adapted to the internet, refining the format of "KDnet," and in 2006, we renewed it as the current "Bid Net" and "Bid Net +α." Since the launch of the service, we have consistently maintained the top position in the industry in terms of information volume, access numbers, and user count.
