CONSULTANT ENGINEERS IN GEOLOGY AND ROCK MECHANICS
SPECIALIZING IN PERMANENT ROCK SUPPORT OF TUNNELS AND CAVERNS, GEOLOGICAL FOLLOW UP,
FIELD SURVEY AND PREINVESTIGATIONS
Tunnel & GeoConsult is a norwegian consultant company based on Norway's long experience
in hard rock tunneling and underground construction.Today the company consists
of 5 engineers and 1 Cad Operator.
Our company has 24 years on site experience in geological follow up
of large scale underground projects in hard rock.
Rock excavation is
continuously followed up and classified according to the norwegian NGI's
Q-system (Rock classification system). Accordingly the permanent rock
support for each tunnel or cavern sequence is decided and installed imediately after
Our CAD operators are designing base drawings of the tunnel sequences
on site work. These are again completed by our engineering geologist on site and form
the base for the daily and weekly reports on permanent rock support to be
installed by the Contractor. In this way the Client also has the full control of
the amount of permanent support ordered and the distribution of the rock conditions.
