Southern Earth Sciences, Inc. served as a subcontractor providing quality control testing on concrete, soil, cement, and asphalt for the construction of a 4-lane bridge, connecting Point Coupee Parish with West Feliciana Parish, La., and covering over 15 miles.

The construction included two approach roads, one on each side of the west and east bank; and had a project cost of over $200M.

SES’s role consisted of laboratory testing, which included: soils investigations for classification purposes, proctors, ph and other mechanical procedures; testing of aggregates for gradation, abrasion and soundness; and testing of concrete for compression. Field work included concrete testing for slump, air, temperature, and consistency. Field tests were also conducted on soil for compaction, soil cement pulverization and spread, and aggregate base for compaction.
