WEBB AND JIM HOGG COUNTIES, TEXAS
Arias provided geotechnical engineering services for the project in 2009. Two separate wind farms were addressed, with the Oilton site located southeast of the intersection of SH 359 and SH 649 in Webb County and the Randado site located northeast of the intersection of SH 16 and SH 649 in Jim Hogg County. Forty-seven (47) wind turbine generators were planned for the Oilton site while 40 wind turbine generators were planned at the Randado site. In addition to the turbines, each wind farm site included underground electrical collection systems, substations, private access roadways, and crane pads. The field exploration program included drilling and sampling at 12 locations and sampling at eight area caliche pits that were to be considered as borrow areas. Laboratory testing was performed to evaluate water content, Atterberg limits, fines content, particle size distribution, moisture-density relations, California Bearing Ratio, and wet ball mill testing for base disintegration.
