The Trimble® Access™ Tunnels software includes powerful tools to define, survey, and report your tunnel. The easy to use interface guides you through such tasks as marking areas of underbreak and overbreak, and positioning machinery. 

The easy to follow workflow for Trimble Access Tunnels guides you through tasks to survey tunnel projects. Utilizing Trimble total stations, over and underbreak profiles are collected automatically and key construction features such as rock bolts and blast holes can be visually set out. Combined with Trimble Business Center office software, comprehensive reports and analysis from field data can be generated to complete the workflow.
