An independent organization within BabEng GmbH (formerly Babendererde Engineers), the Tunnelsoft Division was created in 2005 to develop software which initially supported the engineering endeavors of the company. It later became a business unit in itself with an international team of software engineers and application designers exclusively dedicated to perfecting the product. To do so, TPC software engineers not only take advantage of in-house tunnel engineering expertise but also maintain  close contact and good relations with TPC users world-wide.

The overall goal of Tunnelsoft is to develop tools for customers to help facilitate their day-to-day work on challenging tunnel projects. Tunnelsoft products relieve the user from much of the routine work, thus freeing their valuable time up for real engineering tasks. This goal is combined with general enhancement of tunneling safety providing the user with a clear idea of operations day in and day out, seven days a week.
