Maintenance for Three (3) Liquid Scintillation Spectrometers (LSC) and a Wizard2-24800010 gamma well counter

The contract solicitation is for comprehensive maintenance services covering three liquid scintillation spectrometers and one gamma well counter at the National Institute of Standards and Technology in Gaithersburg, Maryland. The equipment includes specific units with known serial and property tag numbers: the Quantulus-1220, TriCarb-4910 TR, Beckman 6500, and Wizard2-24800010. Service requirements mandate annual preventive maintenance, unlimited emergency corrective maintenance during regular business hours, telephone support, and mandatory submission of detailed field service tickets before departure from NIST premises after each visit. All work must be performed by personnel officially authorized by PerkinElmer, using only manufacturer-approved tools, parts, and methodologies to ensure full compliance with the latest operational and maintenance manuals. The contract operates under a firm-fixed-price structure with a five-year total performance period, structured as a one-year base period followed by four one-year options, all contingent upon government exercise. Delivery is FOB destination, requiring the contractor to cover all shipping and tariff costs, and all services must be rendered at NIST’s 100 Bureau Drive location. This is a total small business set-aside under NAICS code 811210, restricted exclusively to small business concerns, and requires active SAM registration throughout the bidding, award, and performance phases. Offerors must submit a three-volume quotation: Volume I detailing technical capability with explicit evidence linking their approach to every SOW requirement, Volume II containing a separate firm-fixed-price quote valid for 90 days inclusive of all shipping and tariffs, and Volume III addressing applicable provisions and clauses. Technical acceptability is evaluated as a pass/fail gate—no prototypes, refurbished, or demonstration equipment will be accepted; submissions lacking explicit documentation of compliance are automatically rejected. Award will be made to the lowest-priced technically acceptable offeror. The government reserves the right to inspect and test all services, and acceptance is the point at which title transfers. Invoices must be submitted electronically to [email hidden] or via the Treasury’s IPP system and must contain precise details including CLIN, unique entity identifier, cumulative invoiced amounts, and payment terms. The contractor is bound by mandatory clauses including disputes, security prohibitions, prohibition on internal confidentiality agreements, and SAM compliance, and must adhere to labor, anti-trafficking, and conflict of interest regulations. Any submitted quotation constitutes acceptance of all government terms unless exceptions are explicitly stated.
