Dwyer Road Intake Canal
Location: New Orleans, Louisiana
The Dwyer Road Intake Canal project includes the construction of a 7,000 linear foot box culvert at a depth of 14’ to 16’ located in the 9th Ward in New Orleans, Louisiana. The roject requires an Engineered Temporary Retaining Structure, a comprehensive Dewatering Plan and Quality Control. This project consists of 110,000 cubic yards excavation, 86,000 square feet of sheet piling, driving 178,000 linear feet of timber piling, driving 17,250 linear feet of steel pipe piling, extensive utility relocations, and 22,000 cubic yards of concrete for box culvert construction.
This project had to be designed for excavating the saturated soils of New Orleans to an average elevation of -22.0. This required the construction of a Temporary Retaining Structure that was 25 feet wide and had an average excavation depth of 18 feet. Three 500 foot long sections were constructed at the same time to build the 7,000 linear feet of box culvert. Additional items of work include utility relocations, asphalt road work, backfilling, and fertilizing and seeding.
