Vendors must be registered in SAM.gov and provide evidence of Commercial Calibration Activity (CCA) or Original Equipment Manufacturer (OEM) certification/accreditation (e.g., ANSI/NCSL Z540.1, ISO 17025). The award will be based on the Lowest Price Technically Acceptable, considering technical compliance, price, and adherence to schedule. Offerors must also submit a Government Property Management System Plan.

The Portsmouth Naval Shipyard has issued a combined synopsis/solicitation (N3904026Q4761) for Hygrometer Calibration services. This Request For Quotation (RFQ) seeks full and open competition from vendors capable of calibrating Panametrics OptiSonde chilled mirror hygrometers and associated sensors. The base period runs from January 15, 2026, to May 15, 2026, with four one-year option periods extending through May 15, 2030. Performance will occur at the contractor's facility, with equipment shipped to the Portsmouth Naval Shipyard. Quotes are due by October 21, 2025, at 12:00 pm ET and must be emailed. Contractors must be registered in SAM.gov and provide evidence of Commercial Calibration Activity (CCA) or Original Equipment Manufacturer (OEM) certification/accreditation (e.g., ISO 17025) and a Government Property Management System Plan. Awards will be based on the Lowest Price Technically Acceptable, considering technical acceptability, price, and adherence to schedule.

This Statement of Work outlines the requirements for calibrating Panametrics OptiSonde chilled mirror hygrometers and their associated sensors for Portsmouth Naval Shipyard. The vendor must provide NIST calibration for four serialized sets of benchtop units, D-2 sensors, and functional verification for temperature sensors. The vendor must be certified/accredited to ANSI/NCSL Z540.1, ANSI/NCSL Z540.3, ISO 17025, or NAVSEA 04-4734B by A2LA, ANAB, IAS, NVLAP, PJLA, or JNAC, with a current and relevant scope of accreditation. Calibration must be performed at the accredited laboratory, maintaining a minimum Test Accuracy Ratio (TAR) of 4:1, Test Uncertainty Ratio (TUR) equal to or greater than 4:1, or a Probability of False Accept (PFA) not exceeding 2%. A detailed report/certificate of calibration, including before and after measurement data, uncertainties, contact information, date, certificate number, and any out-of-tolerance values, is required. Calibration must use at least six test points from -35.00°C to 25.00°C, adhering to OEM standards. The vendor is responsible for providing a record of calibration, written certification of NIST compliance, and calibration stickers on each unit. The Government will ship equipment to the vendor and review documentation for compliance upon return, with any unauthorized deviations rendering the service non-compliant.

The document addresses calibration service requirements for government procurement, specifically for RFP N3904026Q4761. It outlines three levels of calibration: Traceable Calibration (Level 1), Traceable Calibration with Data (Level 2), and Accredited Calibration (Level 3). Only Level 3, "Accredited Calibration (ISO 17025 with uncertainties)," which includes full data reporting, uncertainty calculation, and an Accredited Logo, is deemed acceptable. This ensures that all calibration services meet stringent ISO/IEC 17025:2017 standards and fall within the scope of accreditation, emphasizing precision and compliance for government contracts.

This government attachment, identified as GFP Attachment, details the provision of four Optisonde Set hygrometers (A, B, C, D) for a program titled "Hygrometer Calibration," under Solicitation Number N3904026Q4761, dated 2025-09-15. Each set, with a unit acquisition cost of $11,500, includes an OptiSonde Bench Top Unit, D-2 Sensors with platinum-chill mirrors (each with a unique serial number), and 4-wire platinum resistance temperature detectors. These items are classified as serially managed equipment, designated for return property usage, and tracked within the ELMS property system. The attachment specifies that the items are to be used "as-is" and are not upgradable.

This document outlines Operations Security (OPSEC) contract requirements for the Portsmouth Naval Shipyard (PNSY), emphasizing the protection of sensitive and critical information (CII). OPSEC is a process to prevent adversary exploitation of sensitive data, whether classified or unclassified. Contractors must sign an OPSEC Plan, which records and monitors OPSEC activities, before the contract's start date. Key contractor responsibilities include safeguarding U.S. Government CII from unauthorized disclosure, prohibiting its distribution to foreign entities, and preventing public dissemination via corporate newsletters, social media, or personal email accounts. The document strictly controls Portable Electronic Devices (PEDs) within the shipyard, requiring sponsor coordination for their use. It also lists Critical Information and Indicators (CII) such as Personally Identifiable Information (PII), operational schedules, equipment capabilities, and critical infrastructure details. Countermeasures include restricting verbal discussions, prohibiting unauthorized photography, shredding sensitive documents, not posting shipyard information on social media, and immediately reporting any compromises of critical information.
