TVA is conducting a subsurface investigation
of the Tellico Dam embankment and underlying foundation rock using geophysical testing.
Approval of the Contract to SJB Services/Empire Geo-Services for subsurface investigation
for the Construction of Fire Training Tower VOTE 3.
The use of vertical electrical sounding (YES) in the subsurface investigation
has increased in recent years.
At this point, a comprehensive subsurface investigation
can be planned and this will require adequate geophysical and geotechnical methods .
--Perform a subsurface investigation
including sample collection;
Novices may be unfamiliar with some of the subsurface investigation
methods he calls for, but that information should be readily available online and in print.
Important geotechnical aspects of the project included a sophisticated subsurface investigation
using specialized field and laboratory testing, an advanced pile and barrette testing program, and a site-specific seismic hazard analysis.
GZA GeoEnvironmental, an environmental consultant to New Hampshire DES, has prepared a draft 2009 data report, which provides a summary, analysis, interpretation and findings of the residential sampling programs, onsite subsurface investigation
, and overburden and deep bedrock groundwater sampling events that occurred at and in the vicinity of the site in 2009 and early 2010.
The TRB subcommittee, ITGAUM, and FHWA jointly are pursuing several initiatives, including evaluating subsurface investigation
methods, developing a manual of best practices, and refining modeling techniques for mine collapses.
DCHC hired an environmental consultant to conduct a Phase I site assessment and a phase II subsurface investigation
, which revealed that five underground storage tanks might still be located on the property and that hazardous liquids might be in the ground.
Existing official information in the form of reports and records can assist subsurface investigation
. These include aerial photographs and agricultural, geological, and topographic maps.
The special conditions section of the contract carried a provision entitled "Subsurface Investigation
," within which this appeared:
