300 Species habitated
$50M in tax dollars saved
Zero lost man-hours
The Details
Contracted by the US Army Corps of Engineers, The Wesson Group expanded existing containment dikes on Poplar Island in Maryland's Chesapeake Bay. Through efficient, 24-hour shift work, zero time was lost in 150,000 manhours needed to complete the $55.9 million project. The expansion required 580,000 tons of imported stone, 830,000 cubic yards of sand, and the placement of 330,000 square yards of geotextile.
Scope of Work
Open water construction
500,000 tons of imported stone, delivered by barge, ranging from 2,500-lb. armor stone to No. 1 crushed stone
On-site relocation of 830,000 CY of sand
Placement of 330,000 SY of geotextile
24-hour shift work
Peak Daily Operations
35 TWG craft workers
2,000 tons of stone placed per day
6,500 CY of sand placed per day
The Challenge
This was a critical infrastructure project for the Chesapeake Bay area, providing both a very economical location for disposing of Baltimore shipping channel dredge disposal and an environmental habitat to support local initiatives and habitat enhancement. The project location was on the very exposed northern end of Poplar Island. The Wesson Group adapted construction means and methods to every changing weather, wind, and tide conditions in order to maintain the high levels of quality control required by the Army Corp.
The Result
Our innovative approaches for stone placement, grade control, and survey technology, as well as our continuous pursuit for value engineering resulted in minimizing material usage and reducing schedule impacts for the project. The result was a cost savings to the owner of approximately $6M.
