Solar farm development and monitoring

Our geotechnical engineers conduct site investigations using Standard Penetration Test (ASTM D 1586), Cone Penetrometer Test (ASTM D 5778), test pits, temporary piezometers, rock coring to provide RQD and Rock Mass Rating Rating (RMR) (ASTM 5878) to assess the subsurface conditions.

UES’ experts understand Direct Embedment Foundations Design and utilize site specific data from load testing. This includes axial tensile, lateral and axial compression load tests (ASTM D 3689, 3966 & D1143) to provide data for engineered foundations by providing data for FAD/MFA analysis.

To be efficient, solar farms need accurate data on the thermal and electrical resitivity of the soils. This is accomplished through field testing using a Wenner 4-pin system (ASMTM D 6431, IEEE Std 81) or equivalent source capable of producing 500 volts. Laboratory testing is performed with in-house
equipment for RHO earth resistivity (D 5334/IE STD 442).

In cases where the soil conditions are determined to be weak or unsuitable, our geotechnical engineers use field collected data such as SPT and CPT data along with laboratory testing (including CBR, R-values, and other index tests) to evaluate remedial ground improvement techniques. These techniques can include soil stabilization using cement or lime or the use of alternative products such as geogrids and geotectile fabrics to strengthen the soils and subgrade and provide support for access roads, allowing for the construction of the solar farm.

  • Direct drive foundation posts
  • Concrete ballast

Our geotechnical engineers take into account the environmental impact of solar farm construction. They analyze the potential for soil erosion, sedimentation, or contamination during and after construction, and provide mitigation strategies to minimize these impacts.

We also assess the site’s drainage characteristics and groundwater conditions by installing temporary piezometers for accurate water elevations and performing infiltration tests such as a Double Ring Infiltrometer DRI (ASTM D 3385). Our experts design appropriate drainage systems and recommend measures to manage surface water runoff and prevent waterlogging, which could affect the stability of the solar farm and its long-term performance.
