Phase one of Norriego stabilization on point
Phase one of the Norriego Point stabilization project is progressing as planned.
“The project is approximately 95 percent complete,” City Engineer David Campbell told The Log in an email.
As part of the initial phase, dredging took place in Old Pass Lagoon and sand from the U.S. Coast Guard dredge project was placed along the point, where the northernmost T-groin had been flanked.
Crews from H.G. Harders and Sons, Inc. have been hard at work as well, as they were tasked with removing the old sheet pile wall along the point and replacing it.
Both the wall and the concrete cap have been completely constructed, Campbell said. He told The Log that 6,000 psi marine mix concrete, which was expected to be fully cured Friday. A total of 18 cubic yards of concrete and 215 linear feet of 16-foot-long sheet pile was used.
As for what’s next, Campbell said test cylinders filled with the same concrete that was used in the wall cap will be “broken” to demonstrate that the cap concrete has cured to, at least, the “design strength” of 5,500 psi.
“Should the cylinder break at the design strength, the forms for the cap are removed, the expansion joints will be cleaned and sealed,” he wrote. “The cap will be covered with the remaining sand stock piled on site and the contractor demobilizing material and equipment and final cleanup of the site.”
Final completion of the project is expected Aug. 1.
