FLAC3D TMis a numerical modeling code for advanced geotechnical analysis of soil, rock, and structural support in three dimensions. FLAC3D is used in analysis, testing, and design by geotechnical, civil, and mining engineers.
This FLAC3D V7.0 training course accommodates new and experienced users. It will be based on examples that attendees will develop and run by themselves to better grasp the mechanics of using FLAC3D V7.0, the key underlying calculation principles and the spectrum of available features. Attendees are encouraged to bring one of their specific cases that may be discussed.
The upcoming 70th annual Highway Geology Symposium will be held in Portland, Oregon, October 21st through October 24th, 2019.
Denver conducted a complex mine pit lake model update and groundwater
model to support a mine closure project in central Nevada. Itasca was
very responsive, met deadlines, stayed within defined scopes and
budgets, and provided us with a quality product to submit to the Nevada
Division of Environmental Protection – Bureau of Mining Regulation and
Reclamation (NDEP-BMRR). Itasca was asked to present their results to
the NDEP-BMRR on multiple occasions and the data was well received by
the agency. I would personally recommend Itasca to anyone in need of a
highly technically and professionally qualified firm for hydrogeologic

"Stillwater Mining Company embarked on a major expansion program,
the Blitz Project, in 2011 at the Stillwater Palladium-Platinum Mine in
south-central Montana. As development progressed into uncharted
territory, influxes of water became more and more of an issue, not only
for the mining group underground, but also for the water managers on surface.
What hydrologic regime were we facing? How best do we manage this
water? Itasca Denver was chosen during a competitive bidding process in
2016 to help us with just these very questions. Itasca jumped right in
and hit the ground running with a crew of experienced hydrogeologists to
address our issues. We were very impressed with their attention to the
underground data-gathering field work and their use of key, experienced
personnel to attack specific tasks. There is a reason the Itasca Denver
crew has been referred to as the “gold (nee platinum) standard” in water
management personnel. They addressed our situation with strong science
and Stillwater was very pleased with the detailed reports and
recommendations that were provided in a timely fashion. Stillwater hopes
2016 is just the first year of a multi-year cooperative relationship
with Itasca on the Blitz Expansion Project."

"The groundwater modeling [IDI] did on the VB/I70 project has
been well received by our client, USEPA Region 8, and the construction
contractor. Of particular note was a comment made in a Core Team meeting
last week by a geotechnical expert who critiqued the modeling for
possible overestimates of flow rates, timeframes, and/or volumes. Not
only did he not find any, he complimented the common-sense approach
taken and thoroughness of the model set-up, calibration, simulations,
and reporting. His wording was that we chose a very qualified team who
delivered an excellent product. He had no arguments with the work
performed. On a personal note, I have enjoyed working with [IDI] on this
project and look forward to more opportunities in the future. Keep up
the good work."

“Very efficient! We spent three days up front
developing the conceptual model. Time well spent! Itasca’s expertise
in hydrogeology and modeling resulted in a quick calibration of the
model. Reporting and communication were very effective! Very pleased
with the entire process and the results! Great value!”
