Use UNITRACC’s Online Tools to alleviate your daily working routine. The self-contained programme modules have for example useful functions for determining identification numbers for the classification of conditions, hydraulics, maintenance and statics at the ready.

In addition, various different calculations can be quickly mastered, and even more complex planning tasks can be implemented decidedly easier with the help of our Applications. As a result UNITRACC accelerates your working processes and therefore gives you more time to concentrate on the essentials.

Calculation of interest

This app calculates the tables, which are included in the guidelines of the LAWA-working committee for the realisation of dynamic cost comparison calculations.

Estimation of the subsidence above the shield machine

This app for the estimation of the subsidence through at ground level in cross direction during shield tunnelling, enables the user to determine the estimated depth of the subsidence and also the estimated subsidence at any distance from the jacking axis. The estimations can be carried out according to the approaches of O'Reilly and New and the critical angle ß-theory.
