A large pipeline company planned to use horizontal directional drilling (HDD) to install three pipelines beneath the Mississippi River and its levees near Empire, Louisiana. The US Army Corps of Engineers (USACE) has become more restrictive in its regulation of construction around Louisiana’s levee system in recent years, especially with images of Hurricanes Katrina and […]

Built in 1955, the Interstate 44 Gasconade River Bridge in Laclede County, Missouri was slated for replacement. The Missouri Department of Transportation (MoDOT) had begun construction of a temporary substructure north of the existing bridge to support a new replacement bridge deck. MoDOT planned to complete the new deck, then remove the old deck and […]

GeoEngineers was part of a design-build team led by Gilchrist Construction Company that was awarded the State of Louisiana’s first completed design-build highway project. GeoEngineers provided geotechnical engineering design services for the technical design proposal to the Louisiana Department of Transportation and Development (LA DOTD). The 1,900-foot overpass of two, two-lane bridges cost the state […]

Record precipitation in Southwest Missouri in April 2008 prompted the US Army Corps of Engineers (USACE) to open all of Table Rock Dam’s floodgates to prevent overtopping the dam. The subsequent flow into Lake Taneycomo below the dam was the highest on record since the dam’s construction in 1958 and resulted in significant scour along […]

The Louisiana Department of Transportation and Development (LA DOTD) contracted with GeoEngineers’ Baton Rouge office to complete a geotechnical investigation, including borings and laboratory testing, for the new Rigolets Pass Bridge and approaches on US 90 outside New Orleans, Louisiana. The $50 million high-rise bridge is a little more than one mile long and has […]

Since Hurricane Katrina flooded much of New Orleans, local and federal authorities have been working to prevent a similar disaster. The Permanent Canal Closures and Pumps Project (PCCP) was an effort by the United States Army Corps of Engineers (USACE) to protect the city by building three new canal closure and pumping station structures at […]

GeoEngineers completed a geotechnical engineering evaluation, design and construction monitoring for the new Interstate 210 (I-210) overpass of Cove Lane in Lake Charles, Louisiana. This fast-paced project required our team to mobilize five different drill rigs for explorations and staff from offices across the country in order to meet the schedule requirements. The goal was […]

The City of Port Arthur, Texas needed to install a pipeline under the Sabine Neches Waterway to carry water from Port Arthur to an industrial facility 12 miles away in Louisiana. This crossing was complicated by the proximity of the Sabine Neches waterway hurricane flood protection levee, an active railroad, busy highway and residential area. […]

Louisiana’s coastline has been losing wetlands at a rate of 16 square miles a year during the past 25 years, equal to the loss of a football field of coast every hour. At current land-loss rates, nearly 640,000 more acres, an area nearly the size of Rhode Island, will be underwater by 2050. The Caminada […]

L’Auberge Casino Hotel is a 575-acre tract that Pinnacle Entertainment developed adjacent to the Mississippi River in Baton Rouge, Louisiana. Designed to capture the feel of a Southern river lodge, the development includes a 74,000 square-foot gaming facility that floats in a man-made lake next to the river channel, a 12-story hotel with 206 guest […]
