AEI supported the USACE Louisville District Geotechnical and Dam Safety programs by providing geotechnical drilling, laboratory testing, and engineering for civil works and military projects through a $2M Geotechnical Services IDIQ contract from 2014-2019. In 2019, AEI submitted qualifications for a follow-on contract and, due in large part to exceptional performance, was awarded a new $3.5M Geotechnical Services IDIQ contract in 2019 which extends to 2024. Task orders to date have included:

• Infantry Platoon Battle Course (IPBC), Fort Campbell, KY Exploratory drilling, laboratory testing, and geotechnical engineering for a Range Operations and Control Area (ROCA) complex. An Ordnance and Explosives (UXO) Safety Specialist escorted the drill crew at all times. Engineering analyses included soil bearing capacity analysis, settlement analysis, determination of lateral earth pressure coefficients for below grade walls, aggregate pavement design, liquefaction analysis, and determination of seismic site class and seismic design category.

• Vehicle and General Purpose Maintenance Shops, Fort Campbell, KY Geotechnical and geophysical, and geothermal investigation to support design and construction. EM38 and EM 61 geophysical surveys helped to identify subsurface anomalies.

• Gill Township Levee System, Sullivan County, IN Geotechnical drilling and installation of piezometers at the Rogers Ditch Pumping Station to investigate subsidence from concentrated underseepage.

• Clarksville Erosion, Clarksville, IN Exploratory drilling and laboratory testing in support of stability analyses and conceptual designs for stabilization of the streambank along the Ohio River. The project was completed within budget and one week ahead of schedule during freezing temperatures.

• Caesar Creek Dam, Waynesville, OH A Screen for Portfolio Risk Analysis (SPRA) categorized Caesar Creek Dam with a Dam Safety Action Classification (DSAC) Class 3 Rating. In support of the Interim Risk Reduction Measures Plan (IRRMP) efforts, AEI completed geotechnical drilling and laboratory testing for a dam stability assessment.

• Veterans Administration Medical Center, Canandaigua, NY  Geophysical investigation of 13.8 acres to support the design and construction of future VAMC facility expansions. The purpose of the investigation was to determine the locations of subsurface anomalies that may be caused by the presence of buried waste material (both metallic and non-metallic) and uncontrolled fill, changes in geologic conditions, old building foundations, below-grade structures, and existing and abandoned subsurface utilities in the accessible exterior portions of the area of interest.
