The Department of Defense, specifically the Department of the Navy's NAVFAC Systems and Expeditionary Warfare Center, is seeking to procure a subscription for Leapfrog Energy Modeling Software on a sole source basis from Bentley Systems, Incorporated. This procurement aims to acquire software licensing and support essential for generating 3D geologic and geothermal models, which are critical for the Navy Geothermal Program Office's operations, particularly at the Coso Geothermal Field. The Leapfrog software has been utilized successfully for four years, and its continued use is vital to avoid operational delays and ensure workflow continuity, as alternative software options do not meet the specific needs of the program. Interested parties may submit capability statements or quotations to the primary contact, China Park, at china.park.civ@us.navy.mil, or the contracting officer, Jonathan Oliveros, at jonathan.c.oliveros.civ@us.navy.mil, with the contract expected to be a firm-fixed price for one base year and four option years.
