CPRA Releases RSIQ for Sediment Diversion Engineering and Design
Louisiana Coastal Protection and Restoration Authority (CPRA) has released a Request for Statement of Interest and Qualifications (RSIQ) for eligible firms interested in providing engineering and design services for the Mid-Breton Sediment Diversion project.
This project is part of the Mississippi River Mid-Basin Sediment Diversion Program, which also includes the proposed Mid-Barataria Sediment Diversion. These two projects will be the first controlled sediment diversions reconnecting the Mississippi River with its delta.
A cornerstone of Louisiana’s Coastal Master Plan, these diversions will provide sediment, water, and nutrients to the basins in order to build, maintain, and sustain the wetlands, complementing the billions of dollars that have been or will be invested in coastal protection and restoration projects, such as marsh creation projects, which utilize Mississippi River dredging, said CPRA.
CPRA seeks a team of consultants to provide engineering services and a final design for the Mid-Breton Sediment Diversion. The chosen team will also play a critical role in CPRA’s selected innovative delivery method for the project, which is known as Construction Management at Risk (CMAR).
This involves hiring the construction contractor during the early design phases to collaborate with the consultant team on engineering, constructability, and costing.
The general location of the Mid-Breton diversion will be north of the proposed Mid-Barataria location on the east bank of the Mississippi River, near Wills Point. The diversion complex is anticipated to include an inlet channel, a gated structure at the Mississippi River Levee, a conveyance channel, outlet channel complex, interior drainage improvements, and highway accommodations.
A Pre-Submittal Conference will be held for potential proposers. The deadline for questions is November 1, 2017. The solicitation window closes on November 20, 2017 and the selection is anticipated to be announced in February, 2018, said CPRA.
