What makes HGI different from the rest? Perhaps it's our innovative approach to solving problems, our ability to think outside of the box and integrate information from different sources. Or maybe it's our commitment to excellence, our willingness to go the extra mile. Or perhaps it's our hands-on approach to doing the work. Everyone ­ up to and including the president ­ spends time working on projects and interacting with clients and vendors. So we're constantly exposed to the latest equipment, software, and techniques in the industry. The bottom line is that we're a small business that is totally focused on getting the job done for our clients, even if that means developing new approaches and/or software to provide the best product.

HGI also offers some highly specialized services that you'll be hard pressed to find elsewhere, such as:

TBM Vibration Monitoring
Monitoring of ultra-low level vibrations produced by tunnel boring machines, trains, moving water, etc. with full waveform analysis using software developed specifically for this purpose.

Tunnel Mapping
Mapping of hard rock tunnels, including development of a relational database for sorting and retrieving data and creating products like steoreonets and rose diagrams.
