Geotechnology Announces Major Expansion

August 18th, 2015

THE_ForProjectsAugust 17, 2015 – Geotechnology, Inc., a leading provider of geotechnical and environmental engineering, geophysics, water resource management, materials testing and drilling services, has announced that it has purchased substantially all of the assets of Thelen Associates. Closing on the transaction occurred on August 17, 2015.

Thelen Associates, an engineering firm founded in 1971, provides geotechnical engineering and construction materials testing services locally in the Greater Cincinnati-Northern Kentucky area, and regionally in Kentucky, Ohio, Indiana and Tennessee. Since 1971 Thelen has provided engineering, testing and construction review services for more than 35,000 projects. Currently, Thelen has 108 employees operating from four offices.

With the addition of Thelen, Geotechnology will have 280 employees operating from 10 offices. The company anticipates that number will increase with expanding project opportunities. This expansion allows Geotechnology and Thelen to efficiently and effectively serve clients throughout the middle part of the country.

Thelen’s projects include transportation infrastructure; commercial, institutional, industrial and retail developments; water/wastewater; dams and levees; and major sports facilities. Representative projects include the Paul Brown Stadium (home of the Cincinnati Bengals), the Cincinnati Reds Great American Ball Park, The Banks Project (a mixed-use development between the two stadiums), and the Kennedy Connector in Cincinnati, Ohio; RiverCenter high-rise office and hotel development on the Covington, Kentucky riverfront; the BB&T Arena at Northern Kentucky University in Highland Heights, Kentucky; the KY 4 (New Circle Road) project and the University of Kentucky Gatton Business School in Lexington, Kentucky; the Kentucky Speedway in Sparta, Kentucky; Kentucky’s new Mountain Parkway Project in South-Central Kentucky; the Lawrenceburg Levee project in Lawrenceburg, Indiana; and the Miami University Farmer School of Business in Oxford, Ohio.

Geotechnology Offices 150817Geotechnology’s purchase of Thelen’s assets is part of a long-term strategic plan of geographic expansion. Founded more than 30 years ago in St. Louis, Geotechnology opened offices in Illinois and Kansas as demand for its services increased. In 2010, Geotechnology purchased Hall, Blake & Associates in Memphis. Earlier in 2015, the company opened two new branch operations in Oxford, Mississippi and Jonesboro, Arkansas. The Thelen acquisition provides a greater presence to Geotechnology’s current Midwest and Midsouth operations.

“This business decision was made based upon careful consideration of how to best augment our resources, assets and service lines,” said Geotechnology President and CEO Ed Alizadeh, P.E., J.D. “Thelen Associates has a highly regarded reputation in the industry, along with excellent staff and equipment. Currently, Thelen Associates does not offer geophysics or environmental services, which have been highly sought after services by our other clients. With more resources available, we will be able to help our clients solve problems and grow their businesses.”

“We are excited to be a part of the Geotechnology family,” said Thelen Associates President Don Thelen, P.E. “The pace of design and construction projects is more aggressive with each passing year. Increasing our capabilities, specialized staff and technologies will afford us even more opportunities and successes.”

EPA publishes final rule regulating coal combustion residuals

December 23rd, 2014

Dec. 19, 2014 – The US Environmental Protection Agency (EPA) published the final rule to regulate the disposal of coal combustion residuals (CCR).  The EPA states that CCR warrant regulatory controls but are not classified or regulated as a hazardous waste.  CCR will be regulated under the Resource Conservation and Recovery Act (RCRA) Subtitle D rules that currently apply to solid waste.  Under Subtitle D, CCR impoundments and landfills are required to have composite liners (or a performance based liner system), leachate collection systems, and a system to monitor groundwater quality.

The rule requires existing unlined CCR surface impoundments that are impacting groundwater above the groundwater protection standards to be closed or retrofitted.  In addition, if a surface impoundment does not meet structural performance criteria, it should be closed or retrofitted.

This rule applies to all new and existing CCR generated by electric utilities and independent power producers.  The beneficial reuse of CCR is not addressed in the new rule but it will continue to be addressed by previous rulings on the beneficial use of CCRs.  The placement of CCR in coal mines and non-utility boilers is not addressed in this rule, but it will be addressed in a separate rulemaking effort.

For further information, the pre-publication copy of the final rule is located at or you can contact Anna Saindon, P.E., R.G., Ph.D. at 314-997-7440.

Daniel Boone Bridge Replacement

September 3rd, 2014

Boone Bridge from BozFrom March to November 2013, Geotechnology, Inc. performed work on the Daniel Boone Bridge, which carries Interstate 64 across the Missouri River, joining the counties of St. Louis and St. Charles, Missouri.

Geotechnology was selected to perform the work due to their responsiveness, expertise and safety record. In its’ 30-year history, Geotechnology has successfully completed numerous near-water and over-water projects, including the recently opened Stan Musial Veterans Memorial Bridge which spans the Mississippi River at downtown St. Louis.

The Daniel Boone project includes replacement of the 1930’s era westbound bridge with the construction of a new bridge over the Missouri River. Foundation inspection holes were drilled within the footprint of each drilled shaft to confirm the rock quality below the bearing surface of each drilled pier (i.e. end bearing design).

The project presented a few challenges to the crews drilling through more than 100’ of alluvial deposits consisting of clays, silts, sands and cobbles that were in close proximity to operating vibratory caisson rigs installing large-diameter steel casings to the top of rock. Drilling for the riverine shafts was done from a contractor-provided elevated platform over the Missouri River and over fully excavated drilled shafts with unsupported span lengths of up to 12’. Because the rig could only be moved from pier to pier by a crane working from a spud barge, the team had to use a small, light-weight, skid mounted drill rig. The mast heights and inability to hoist equipment further than 15’ at a stretch added to the time required to perform the work.

To facilitate bedrock coring using NQ-sized tools, the contractor assembled 4 inch heavy wall pipe in welded sections and lowered that assembly into the 8-12 foot diameter steel casings. The casings were set to the apparent top of bedrock ranging from 80–112 feet below the working platform. Extreme lengths of unsupported casings caused bowing and twisting which added another layer of complexity to the project.P1000373

Geotechnology, Inc. completed the land borings using their CME 85 truck-mounted rig and CME 55HT truck-mounted rig and Rig Source, Inc. provided the skid-mounted Diedrich D50 for the overwater portion of the project.

In total, the project required the installation of 42 Foundation Inspection Holes, consisting of 1,950 feet of rotary drilling and 903 feet of NQ2 Rock Coring and 444 rig hours on-site. Geotechnology’s work was completed without accident or injury.

Doug Lambert, RG Sinkhole Interview with KSDK

March 7th, 2013

March 7, 2013 – St. Louis, Missouri

We’ve all seen the horrific pictures of the sinkhole in Florida that swallowed up a man while he was sitting in his bedroom.  KSDK-TV (NBC) in St. Louis wanted to know if such a tragedy happen could happen here in the St. Louis area?  Reporter Grant Bissell interviewed Geotechnology’s Doug Lambert, RG, Geophysical Group Manager about sinkholes.  Doug did a terrific job in explaining what sinkholes are, how they are formed, and why, despite our area having a high number of sinkholes, a tragic collapse like the incident in Florida would likely not occur here.  The story aired on KSDK’s 6pm newscast on Wednesday, March 6.
