14. DESCRIPTION OF AMENDMENT/MODIFICATION (Organized by UCF section headings, including solicitation/contract subject matter where feasible.)

The purpose of this amendment is to provide questions and answers that were received on or before the closing date of May 15, 2024 at 1500 ED.

1. Question: The PWS specifies Structure-from-Motion (SfM) photogrammetry as a requirement for the project. This implies a preference for a conventional GIS approach that uses imputed 3D geomorphology. However, with current AI technology, it is practical to infer geomorphology end-to-end, without using an explicit 3D model. Such an AI-native architecture would replace reductionist 3D photogrammetry and GIS-based geomorphology with a single neural model (i.e., 2D pixels in ¿ flooding and erosion impacts out). Please clarify if the Government is strictly requiring SfM photogrammetry and imputed 3D mapping or if a fully AI-native architecture is an acceptable alternative?

Answer: We are requiring SfM photogrammetry and imputed 3D mapping. This includes 4D approaches to reduce errors to state-of-the-art levels.

2. Is an active facility clearance necessary for this task? Additionally, if the contractor already holds a top-secret facility clearance would that be advantageous for this project?

Answer: No clearance is necessary for this work.
