International Dredging Review
MENUMENU

Great Lakes Dredge & Dock Corporation (GLDD) has received dredging awards totaling $91 million.

The awarded work includes:

·         Virginia Beach coastal protection ($22.6 million);

·         Sandbridge, Virginia, coastal protection ($20.3 million);

·         Galveston, Texas, Ship Channel maintenance ($21.2 million);

·         Freeport, Texas, LNG Basin maintenance ($4.6 million)

·         San Jacinto, Texas, variation order ($17.1 million) and

·         Missouri River, Nebraska, 2019 floods, emergency levee repair ($4.7 million).

The scope of work for the coastal protection projects includes using sand dredged from offshore borrow areas to rebuild dunes and restore shorelines eroded by winter storms. Work will be performed by hopper dredges. The projects will be executed in the second half of 2019 and into 2020.

The Galveston Ship Channel contract will restore the Galveston Ship Channel in Texas to its authorized navigable depth. Some of the dredged material will be pumped on Galveston beaches as beneficial use. Work on this project will be completed by the end of 2019. Within the Freeport LNG Terminal basin, Great Lakes will perform maintenance dredging to make way for the commissioning of Freeport LNG Terminal’s first cargo.

The San Jacinto variation order is an extension to the project Great Lakes performed in the first half of this year. The San Jacinto project was the first major Houston-area flood-control project after Hurricane Harvey and is continuing the work of reducing the flood risk and restoring a two-mile area of the San Jacinto River to its pre-Harvey state. This project will be executed in the second half of 2019.

Great Lakes is a subcontractor to Western Contracting for the Missouri River floods emergency levee repair project and will be using the cutter suction dredge Iowa. The goal is to stop the flow of water through the breeched levees so repairs can be made to areas behind the damaged levee. This work will be executed this summer.
