The contractor shall provide ISO 17025 accredited calibration services for the Test Evaluation Division/West Desert Test Center. Specific tasks include:

• Four annual on-site calibration visits per year, potentially spanning multiple days.

• Annual on-site calibration for analytical balances, flow meters, and flow controllers.

• Biennial calibration for digital thermometers.

• Calibration for weight sets every three years (on-site or off-site).

• Delivery of detailed ISO 17025 compliant calibration reports with new calibration date stamps.

• Accommodation of changes in the Government's equipment inventory (annual adjustments).

• All-inclusive pricing covering services, travel, and shipping for weight sets.

• The contract type and period of performance are not specified in this notice.

• This is a Special Notice, not a solicitation for proposals. Interested parties are responsible for monitoring SAM.gov for future information.

• This is a Sole Source acquisition, with no set-aside mentioned.

• The following equipment requires calibration: analytical balances, flow meters, flow controllers, digital thermometers, and weight sets. A table detailing specific models, quantities, manufacturers, and calibration frequencies is provided.

Statement of Work (SOW) / Performance Work Statement (PWS)

• Calibration reports must be submitted to the COR within five business days of service completion.

• A new calibration label/stamp must be applied immediately following calibration.

• Period of Performance: One (1) Base Year (2026) with four (4) 12-month option years (April 30, 2026 - April 29, 2031).

• Place of Performance: Combined Chemical Test Facility (CCTF) and Bushnell Material Test Facility (BMTF) at West Desert Test Center (WDCT)/Dugway Proving Ground (DPG).

• Contractor must operate a laboratory formally accredited to ISO/IEC 17025 by a recognized accreditation body.

• Service technicians must have documented education, training, and experience relevant to the calibration tasks.

• Contractor must verify US citizenship of personnel performing services at Dugway.

• All contractor employees must complete required training, including Anti-Terrorism (AT) Level I, Information Assurance (IA), iWATCH, and OPSEC Level I training.

• Contractor must maintain ISO 17025 accreditation throughout the contract period.

• A Quality Control Plan (QCP) must be developed and maintained.

• The contract type is anticipated to be Firm Fixed Price (FFP).

Statement of Work (SOW) / Performance Work Statement (PWS)

This document outlines the performance requirements for calibration services, likely for equipment used at Dugway Proving Ground (DPG).

• Schedule Coordination: The contractor must coordinate four annual on-site calibration visits, including travel and providing necessary calibration equipment. Equipment must be functional, recently calibrated, traceable to NIST or equivalent standards, and appropriate for the DPG equipment.

• ISO 17025 Accreditation: The contractor must provide proof of accreditation to ISO 17025 by a recognized body (e.g., A2LA) and demonstrate that their technicians are certified and trained for the specific calibration tasks.

• Training: All required training must be completed before performing services at DPG, with documentation submitted to the COR at least 24 hours before the initial service.

• On-site Calibration Tasks: Specific calibration tasks are detailed for:

  • Analytical Balances (according to validated ISO 17025 procedures)
  • Digital Thermometers (at 4°C using a traceable reference)
  • Flow Meters & Flow Controllers (0-2 L/min range, using SI traceable standards, tested at five points)
  • Weight Sets (Class 1, using national standards, traceable to ISO 17025)

• US Citizenship Verification: US citizenship of personnel performing services at Dugway must be verified and sent to the COR within 24 hours of scheduling service (this requirement may not apply if the same technician performs service consecutively).

• Zero Deviation: The performance threshold for all tasks is "Zero deviation from the standard."

• Non-conforming Services: Non-conforming services will result in non-conformance reports and potential negative CPARS reports. The contractor will be required to re-perform the service.

• On-site calibration visits are scheduled annually.

• Calibration of weight sets can be performed on-site at DPG or off-site at the contractor's facility.

• Deliverables: For each calibration event, the contractor must provide:

  • An ISO 17025 compliant calibration report with all relevant data and traceability.
  • A calibration stamp/label affixed to each instrument.

• Calibration Cycle: Equipment is calibrated annually, except for digital thermometers (every two years) and weight sets (every three years).

• Weight Set Shipping: For off-site calibration of weight sets, the Government will ship them, and the contractor is responsible for all shipping costs and returning them within 14 days of receipt.

• Report Submission: Calibration reports must be submitted to the COR within five business days of completing services.
