BAYOU DUPREE SECTOR GATE - Levee Improvements

The Bayou Dupre Sector Gate is a U.S. Army Corps of Engineers Hurricane Protection Office HPO Project. The project uncludes the construction of the Bayou Dupre sector gate structure located on the flood side of the existing structure.

The new sector gate will consist of a pile-foundation and and will be tied into flood control levees by pile founded T-walls with a sheet pile cutoff wall and scour protection provided at the transition zones.

Southern earth Sciences, Inc. has provided field investigation and laboratory testing services for this levee improvement project including the subsurface drilling, sampling and laboratory testing of soil borings, Inclinometer and Plezometer installations and monitoring.

UNIVERSITY OF SOUTH ALABAMA - Mitchell Cancer Institute

A multi-story cancer research facility providing over 110,000 square feet of space for laboratories as well as clinical services. Southern Earth Sciences, Inc. performed subsurface investigation services including twenty-eight (28) Cone Penetrometer Test (CPT) soundings and four (4) soil borings with Standard Penetration Tests (SPT) to depths of up to 100 feet below existing grade.

Geotechnical engineering services included site preparation considerations and foundation recommendations. SESI also provided consulting services for ancillary structures such as generators and assocaiated underground fuel tanks, elevated pedestrian bridges, and protection of an existing underground structure.

During construction, SESI provided assistance in the planning, performance and evaluation of pile load testing, impulse-echo pile integrity test, and construction materials testing for earthwork and concrete.

FLORIDA DEPARTMENT OF REVENUE - Office Buildings

The Florida Department of Revenue Office Buildings project consists of three (3) buildings (two five-story and one two/three-story) in southeast Tallahassee, Florida.

Southern Earth Sciences, Inc. performed geotechnical investigations for proposed stormwater facilities, parking areas and buildings.

SESI is also monitoring compaction grouting and performing all compaction, concrete and asphalt testing for this project.

INNER HARBOR NAVIGATION CHANNEL - IHNC Surge Barrier

A U.S. Army Corps of Engineering project, the IHNC Surge Barrier is similar to a floodwall but on a much larger scale and is designed to reduce teh risk of storm surge to some of the region's most vulnerable areas - New Orleans East, metro New Orleans, the 9th Ward and St. Bernard Parish. This project aims to protect these areas from storm surge coming from teh Gulf of Mexico and Lake Borgne.

The project is being constructed near the convergence of the Gulf Intercoastal Waterway (GIWW) and the Mississippi River Gulf Outlet (MRGO). Navigation gates are being constructed where the barrier crosses the GIWW and Bayou Bienvenue, and near Seabrook where the IHNC meets Lake Pontchartrain to block the storm surge from entering the IHNC from teh lake.

Southern Earth Sciences, Inc. has provided drilling, laboratory testing, construction materials testing services including soil and cement testing services including soil and cement testing, concrete testing and welding inspection services for several different areas of this massive project.

PIER PARK - Shopping and Entertainment Center

Sotuhern Earth Sciences, Inc. conducted geotechnical investigations and performed construction materials testing during construction of this 1.1 million sq. ft. regional lifestyle center with open air dining, unique shops and tourist attractions developed by Simon Property Group, Inc.

Located on Front Beach Road in the heart of Panama City Beach, the $100 million plus project includes lead stores Target, Dillard's and J.C. Penney with unique stores such as Ron Jon's Surf Shop and Margaritaville. A 16-cinema "The Grand" Rave theater, is also included.

SESI started this project in 2000 with testing for stormwater and infrastructure design. Geotechnical work progressed with Target (2005), Dillard's and J.C. Penney's (2006-2008) as well as multiple stores. Hundreds of standard penetrometer soundings were completed during each phase of the project. Complications to construction included organic soil deposits, loose sands and shallow groundwater.

Most of the 370,000+ sq. ft. of specialty retail shops officially opened in February, 2008.

EADS NORTH AMERICA KC-45A - Aerial Refueling Tanker

Southern Earth Sciences, Inc. provided extensive geotechnical and environmental investigations for the 165-acre site. The project consists of large assembly hangars with column loads up to 300 kips, multi-story workshop/office space, taxiways and aircraft stations.

The geotechnical field investigations consisted of eighty-one (81) cone penetration tests (CPT) to depths up to 125 feet; nineteen (19) soil test borings with standard penetration tests and undisturbed samples performed to depths up to 100 feet; and five standpipe piezometers were installed to measure fluctuations in the potentiometric surface.
