- Description
- NAICS Code: 541710 The U. S. Environmental Protection Agency (EPA) intends to negotiate a single source purchase order, using FAR Part 13 procedures, to modify and improve the EPA's current version of TOPMODEL-GEM developed by the Georgia Institute of Technology. EPA believes that the Georgia Institute of Technology is the only reasonably available source capable of satisfying the Government's requirements as stated below. The circumstance permitting soliciting from a single source is FAR 13.106-1(b), "...contracting officers may solicit from one source if the contracting officer determines that the circumstances of the contract action deem only one source reasonably available..."The improvement to the TOPMODEL-GEM will specifically address the down-slope transport of water and nitrogen (N) through the unsaturated (near surface) zone of soils and the dynamics and interaction of the saturated and unsaturated zones, specifically (1) the content and movement of water within multiple soil layers and (2) the content and movement of dissolved inorganic nitrogen (DIN, as nitrate and ammonium) and dissolved organic nitrogen (DON in water within each soil layers, and (3) partitioning of the dissolved N between sorbed and dissolved forms. The improved model shall also explicitly include state variables for each soil layer for both DIN and DON and a texture-dependent constant for partitioning these between sorbed and dissolved forms. The program code for the integrated TOPMODEL-GEM will be written in MATLAB. The model shall include interactions among water and nutrient (carbon and nitrogen) cycles in vegetation and soils, at spatial and temporal scales ranging from stands to watersheds and days to centuries. The program design shall accommodate spatially-distributed applications that simulate topographic controls on water and nutrient transport in a variety of terrains, including the Central Plains and Cascade Range of the Pacific Northwest. The successful offeror will be required to demonstrate its quality assurance (QA) capability to conform to ANSI/ASQCE4 and EPA Order 5360.1 A2. For more information on these QA requirements visit: ttp://www.epa.gov/QUALITY/faq4.html. Interested persons seeking to challenge the single source justification must present, in writing, clear and convincing evidence of their capability to provide the requirements within 15 days after the date of publication of this notice along with pricing information that is sufficient to make a determination that competition is feasible. Period of performance is expected to be approximately one year from award of the purchase order. No Request for Quote is available.
