AGENDA

Opening Remarks/Administrative Items R. Ellis Screws – Contracting Officer, Vicksburg District Project Overview Mike Renacker - Project Manager Technical Details of Primary Construction Actions David Randolph - Technical Lead Acquisition Planning R. Ellis Screws Closing Remarks R. Ellis Screws

AUTHORITY – Authority: Flood Control Acts 1941, 1950, Section 3(b)); 1944 (Section 10); 1965 (Section 204);

WRDA 86, Section 103; WRDA 96, Section 202 authorized the project to protect a portion of the Yazoo Basin against all but large floods of the Mississippi River.

DESCRIPTION – The Yazoo Backwater Area (YBW) project is in west-central Mississippi, immediately north of Vicksburg, Mississippi. The YBW is bounded on the west by the left descending bank of the Mississippi River Levee, the Yazoo Basin escarpment on the east, and the Yazoo River on the south. The area contains approximately 1,074,000 acres and has historically been subject to flooding from backwater by the Mississippi River, as well as headwater flooding from the Yazoo River, Sunflower River, and Steele Bayou. The project has four major features: The Yazoo Backwater Area levee, associated water control structures, connecting channel, (all were constructed by 1978) and the Yazoo Backwater Area pumping plant (unconstructed). The unconstructed pumping station is a component of USACE’s Yazoo Backwater Water Management Plan.

PROJECT OVERVIEW

PROJECT SCOPE

The current design of the Yazoo Backwater Pumping Plant (YBWPP) is a 25,000 CFS pumping plant located adjacent to the Steele Bayou Drainage Structure. The pumping plant will be operated when the Steele Bayou Drainage Structure is closed and will manage water levels in the Yazoo Backwater

Area to an elevation of 90 feet at the Steele Bayou gage during crop season (25 March - 15 October) and to an elevation of 93 feet at the Steele Bayou gage during non-crop season (16 October – 24 March).

The following information is based on a 10% conceptual design. Scope and quantities will change as the design matures.

CONTRACT #3: ACQUISITION PLANNING

PUMPING PLANT CONSTRUCTION

PUMPING PLANT, Magnitude of Construction and Bonding Requirement; Over $1Billion

USACE is considering awarding the Pumping Plant through a PreQualification of Sources (DFARS 236.272)

Phase-One (occurs prior to 30% design): www.sam.gov posting to select & short-list a group of qualified offerors

Early Contractor Involvement (ECI):

•Stipends awarded to each prequalified contractor.

•Seeking contractor input/design review comments at 30%, 60% and 90% design.

Phase Two: (occurs at design complete): Issue solicitation with evaluation factors. ONLY available to the prequalified group of offerors who then participate in a Competitive Source Selection for Contract Award.

(evaluation factors to be determined).

TECHNICAL QUESTIONS / MARKET

RESEARCH

1. Describe your plan for self-performing work, subcontracting the work, and/or engaging in a Joint Venture. What key features of this project would you self-perform and what key features would you subcontract?

2. The project site is in a rural area, accessed by MS HWY 465, with limited public utilities, and subject to flooding events on the Mississippi and Yazoo Rivers. What are your anticipated needs for an on-site laydown area, temporary utilities, and security/access control? How would you plan to obtain these services?

3. The Yazoo River may be needed to transport riprap and heavy equipment (valves, cranes, piles, bridge girders, etc.) due to roadway limitations. What type of offloading facility would be needed and what are the minimum draft requirements?

4. Borrow material may need to be hauled from up to 6 miles away. What solutions can you propose for delivering this material to the site efficiently?

5. What potential supply chain, transport/delivery, temporary storage, or Buy America Act compliance risks do you foresee for the following specialty and/or long lead items? How would you mitigate those risks:

a. Structural Steel

b. Piling

c. 14 total 1800 cubic feet per second (cfs) vertical axial pumps

d. 14 total 5000 HP (approximate) electric pump motors with starters

e. Mass Concrete (ready mix versus onsite batching)

f. Up to 75-ton (estimated) overhead bridge crane within pumping plant building

6. Construction funding for this project is expected to be received incrementally, leading to multiple construction contracts based on severable features of work. The current proposed plan includes the following separate contracts:

a. Civil Site Work (e.g., preload/overburden for the pumping plant foundation, temporary access roads)

b. Construction of inlet and outlet channels

c. Pumping Plan Construction (including all vertical construction, installation/testing/commissioning of the pumps, motors, overhead crane, and associated M/E/P systems, physical security systems, site access, site utilities, etc.

It is likely that the contracts may need to be broken down into even smaller features of work. How would you propose structuring or phasing the work to accommodate incremental funding?

7. For the Site Preparation/Foundation and Channel Excavation work, the government is considering using a Single Award Task Order Contract (SATOC) awarded via a Best Value Trade Off Source Selection. We are seeking industry feedback on three (3) potential structures:

a. A single SATOC to issue one (1) or more Task Orders for the Site Preparation – Foundation project only.

b. A single SATOC to issue one (1) or more Task Orders for the Channel Excavation project only.

c. A single, larger SATOC to issue multiple Task Orders that combines both the Site Preparation and

Channel Excavation projects.

8. For the Pumping Plant construction, the government is considering a two-phase acquisition strategy using Pre-Qualification of Sources (DFARS 236.101-70). We are seeking industry feedback on this entire process:

• Phase 1: Pre-Qualification: A sources sought notice will be posted on SAM.gov to select and create a short-list of pre-qualified offerors.

• Interim Phase: Early Contractor Involvement (ECI): Each pre-qualified firm will be awarded a non-negotiable fixed amount stipend to provide design review comments and input at the 30%, 60%, and 90% design milestones.

• Phase 2: Final Solicitation: After the design is finalized, a competitive solicitation will be issued only to the pre-qualified group for the final contract award.

What feedback, issues, or benefits does industry see with this two-phase approach, including the use of non-negotiable, fixed-amount stipends for Early Contractor Involvement?

9. Is there any additional feedback you would like to provide regarding the technical design aspects or the proposed acquisition approaches for this project?

FOLLOW UP INSTRUCTIONS

The Government will also be offering one-on-one sessions with prime contractors only, for the purpose of receiving individual industry input from the attached list of questions.

Information obtained in these sessions will be used to improve the final project designs and inform market research for procurement planning purposes.

Please note that these one-on-one meetings are not intended to be general capability briefings. These sessions are not considered opportunities for contractors to market their firms. The sessions will be held on the following days:

27 April 2026 through 01 May 2026

Prime Contractors interested in participating in a one-on-one meeting will be required to request a date and time in advance by emailing Kasey

Davis at Kasey.T.Davis@usace.army.mil.
