Projects Designed to Get Results

AEI geotechnical, surveying, environmental, and materials professionals provided services for this high-profile project necessary to fill and stabilize voids in both the earthen portion and karst bedrock foundation of the high hazard Wolf Creek Dam on Lake Cumberland.

Potential Failure Modes

The purpose of the Dam Remediation and Outlet work project is to control seepage and internal erosion of the earthen portion of the dam. The project consists of a vertical concrete cutoff wall, chimney filter, void filler piles, downstream filter modification and steel liner within the principal spillway. AEI is under contract to provide construction materials field and laboratory testing and inspection in support of the project.

AEI was the lead design firm for a four-year, $180 million design-build construction project including improvements to I-265, I-64 and I-71 through a heavily traveled corridor in Jefferson and Oldham counties, KY. The overall project includes over 28 miles of roadway re-construction and widening, eight bridge widenings, five new bridges, 5.7 miles of noise barrier walls, and nine RCBC extensions. The objective of the project was to improve safety, relieve congestion, lessen construction impacts and provide lower-cost solution while improving the roads and bridges with available funds. The project will be completed in 2023, three years earlier than estimated with the traditional design-bid-build approach.

AEI was on the team for preliminary design, final design, right-of-way activities, and utility engineering to deliver section one of the preferred alternative for the I-69 Ohio River Crossing from the south side of Evansville, IN across the Ohio River southeast of Henderson, KY. AEI’s role included design of a Tight Diamond Triple Roundabout. We created a 3D model and rendering of the proposed concept utilizing Bentley’s OpenRoads and LumenRT for use in a virtual reality (VR) model to communicate the operations and impacts of the proposed roundabout in a manner the general public, stakeholders, and adjacent property owners could comprehend.

Ohio River Crossing

Mainline alternatives were studied that would utilize the existing parkway bridges over I-65 or alternatives that would move the location of the interchange and provide new bridges. Maintenance of traffic was a primary concern for all alternates. The alternate for relocating the interchange required traffic to be maintained on the existing trumpet interchange, therefore, the existing ramps and bridges had to be incorporated into the maintenance of traffic plan. Of particular importance were the existing bridge piers that required additional merge and diverge analysis, as well as, weaving analysis to ensure proper traffic flow throughout construction. Phase II roadway and structural design also had to accommodate the widening of I-65 through the project area.

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:

Logan Aluminum, Inc. (LAI) had plans to expand several production lines at its Logan County, Kentucky, facility and the work had to be completed under strict time schedules while the facility was still in operation. AEI provided surveying, geotechnical, electrical resistivity imaging (ERI) and testing, and inspection support on a variety of interrelated projects including the Hot Mill Building Expansion, the Cold Mill 4 East Expansion, and the SL4 Expansion. AEI also provided civil solutions for a gravel parking lot complete with improved drainage and settling basin to capture area runoff for water quality protection.

Our size, in many instances, is an asset to our clients. We can provide the flexibility much larger firms cannot offer. This pleases our clients and builds on our current reputation. We want you to be our client. We are extremely optimistic about our future and want to share it with you.

During a reflective moment not long after celebrating our highest revenue year ever and after receiving our PSMJ “Circle of Excellence” recognition, I dusted off our very first brochure, printed in 1983. In the cover letter I emphasized AEI’s advantages in two particular areas - size and flexibility - stating: “Our size, in many instances, is an asset to our clients. We can provide the flexibility much larger firms cannot offer. This pleases our clients and builds on our current reputation. We want you to be our client. We are extremely optimistic about our future and want to share it with you.” It strikes me now that my optimism was prophetic and that - amid an ever growing mega-firm environment – our size and flexibility advantages are just as prevalent today as they were then, even after we have grown exponentially in staff, services, talent, clientele and recognition. I am very proud of what we have been able to accomplish at AEI, the staff we have grown and the clients we have served. My feelings toward our potential have only expanded and accelerated. Another comment from that letter also is just as true as it was then – We want you to be our client. Look at what AEI has to offer. I know you will be impressed.
