Xray Tomography Software

The contract solicits X-ray tomography simulation software under solicitation number 1333ND26QNB030268, issued by the National Institute of Standards and Technology within the Department of Commerce, with a response deadline of July 13, 2026. This is a full and open competition under NAICS code 513210 for Software Publishing, using simplified acquisition procedures to award a single firm-fixed-price purchase order. The deliverables include one permanent license of XCT simulation software for use on a single computer via Windows remote desktop and a one-year maintenance contract, both to be delivered electronically or physically to NIST in Gaithersburg, Maryland. The software must simulate X-ray energies from 1 keV to at least 450 keV, support monochromatic and polychromatic spectra, handle 3D surface meshes in STL format with Boolean operations, model scattering via Monte-Carlo methods, enable circular, laminographic, and custom scanning trajectories, generate radiographs in TIFF format, and allow parameter variation through scripting. The offeror must demonstrate full technical compliance through detailed evidence in Volume I, citing specific sections of the Statement of Work, with no allowance for prototypes, demonstration models, or used equipment. Evaluation is based on a pass/fail technical capability gate, followed by award to the lowest priced technically acceptable offeror. The contract requires compliance with extensive federal regulations including the Buy American Act, Equal Opportunity and Child Labor provisions, Combating Trafficking in Persons, Addressing DEI Discrimination, and Prompt Payment Act. All invoices must be submitted electronically to INVOICE@NIST.GOV through the Treasury’s IPP system and must include the contract number, unique entity identifier, CLIN, description of services, and cumulative invoiced amounts. Payment terms adhere to the Prompt Payment Act and regulations at 5 CFR part 1315. The software must comply with federal cybersecurity standards including FISMA, OMB Circular A-130, FIPS 200, and NIST SP 800-171, with SPII encrypted in transit using TLS 1.2 or higher and at rest using FIPS 140-2/3 validated modules. The solution provider must also adhere to prohibitions on inverted domestic corporations, delinquent tax liabilities, and felony convictions, and must provide documentation confirming manufacturer authorization. Submission must be divided into three volumes — Technical Quotation, Price Quotation, and Terms
