Venice to Campbell Transmission Line, Mississippi River Crossing – Venice, IL

Ameren

Ameren retained Reitz & Jens as the lead geotechnical engineer during design and construction of the foundations for a new double circuit 138kV transmission line to carry electric power across the Mississippi River from Illinois to Missouri. The project required two new 310-foot-high steel lattice towers, both within 150 feet of the existing Mississippi River floodwall and Illinois levee system. The foundations for each new structure consisted of eighty-six (86) driven pipe piles seated on limestone bedrock up to 95 feet below grade. The superstructure was connected to piles using a pile cap and pedestal structure that required over 900 cubic yards of concrete and 60 tons of reinforcing steel. 

Reitz & Jens performed the geotechnical investigation for the transmission line, drivability analysis for pile driving hammer selection, and construction quality assurance during construction of the towers. The CQA for this project included monitoring pile load testing on initial production piles (CAPWAP analysis), pile installation records, reinforcing steel verification, and concrete testing.
