Sandvik Construction provides solutions for construction industries in niches such as quarrying, tunneling, demolition, dimensional stone, recycling and civil engineering.


The TCAD+ add-on instrumentation for Sandvik DT and DD series underground drill rigs significantly improves drilling accuracy. Therefore, it also decreases the amount of over- and under excavation.

It is an aiming tool designed for pre-designed drilling plan execution, featuring face drilling, long hole drilling and bolting hole plans on the screen. With its built-in data collection, TCAD+ provides information on hole position and angle logging as well as the drilling process. By improving the accuracy of drilling, the TCAD+ enables optimization of the whole tunneling project at hand: less loading and hauling, blasting, and concrete spraying means less time and money spent. In addition, high drilling accuracy gives more control over blasting, translating into improved overall safety.

TCAD+ is delivered together with Sandvik iSURE® tunnel process management software. This allows curve and drill plan design, and data analysis.
