Maintenance of Regional Sediment Management (RSM) Program Navigation Sediment Placement Database

The ERDC Coastal and Hydraulics Laboratory (CHL) is seeking potential sources for the maintenance the USACE Regional Sediment Management (RSM) Program Navigation Sediment Placement Database. Potential vendors are invited to provide capabilities and potential solution via email to both Kasey.T.Davis@usace.army.mil and CHL-CT-Quotes@usace.army.mil not later than 12pm (CST) 30 May 2023. Please add Email Subject "Sources Sought Response - RSM Database" to your response. Quotations are not sought at this time.

When providing a response, please provide CAGE Code, UEI, and Socioeconomic Indicators (if applicable).

Requirements for this action are listed below:

1) Assist the RSM Program with the FY24 update to the Navigation Sediment Placement Database (“database”).

The FY24 update of the database will involve detailed steps (both in computer coding and personal conversations) that occur each year when new DIS data and internal District datasets are added to the database. In the computer coding piece, tools using Python programming have been developed to minimize future work when importing new or updated data. A semi-automated method aids with quality assurance and documents the methods used when combining the datasets.

For example, a consistent approach to QA-QC with all inland and coastal districts has been implemented and refined for this project in the past. Statistics are provided in advance to district staff for review. PIs from this project, RSM Program staff, a CHL staff liaison, and District personnel are invited to attend interviews to obtain concurrence with the information being presented. Often, additional QA-QC work is required or the District provides an internal database to the project team. The end goal is to ensure that the database is displaying, and the products publish, data that are confirmed by District staff and consistent with other District (or National) products.

The personal conversations piece includes quality checking the existing and newly imported data through district interviews and/or using information that was provided during previous discussions. Interviews with District staff (via phone, email, in-person, or virtually) will be conducted as needed to quality check the project database.

Deliverable: The deliverable for this phase is a database in ESRI geodatabase format which will become intellectual products of the federal government.

2) Refine revised placement categories co-produced with the RSM team in 2023.

In 2023, DIS 2.0 was released and classification and naming conventions for dredge projects were altered. New categories were co-produced by the RSM team in 2023, and those categories require refinement and application FY24 data. Comparisons between BUDM volumes tracked during past years to total BUDM volumes in 2024 will need to be made to ensure the refining process is successful and accurate.

Deliverable: The deliverable for this phase of the project is a refined set of new disposal and placement categories for the database to be compatible with DIS 2.0.
