STATEMENT OF REQUIREMENTS

Rapid Chloride Permeability Test (RCPT) Equipment

I. BACKGROUND INFORMATION

The National Institute of Standards and Technology (NIST) Engineering Laboratory (EL) Materials and Structural Systems Division (MSSD) studies the durability and service life of infrastructure materials (polymers, concrete, engineered composites, etc.) for resilient infrastructure applications.

One of the key research focuses is to evaluate the durability of these materials to environmental factors that could expedite deterioration. One such environmental factor that can impact the long-term structural integrity of concrete structures is exposure to chloride ions (Cl-). The MSSD will benefit from rapid chloride permeability test (RPCT) equipment to evaluate concrete materials in the “Engineered Materials for Resilient Infrastructure” program in projects such as “Assessing Pyrrhotite in Concrete”, “Forward Looking Building Codes”, and “Additive Manufacturing with Cement Based Materials” as well as Disaster and Failure program investigations such as Champlain Towers South.

II. PURPOSE

The MSSD requires a rapid chloride permeability test set-up to measure chloride-ion penetration of concrete.

III. MINIMUM REQUIREMENTS

The Contractor shall deliver a quantity of ONE (1) voltage application and data acquisition system to measure applied voltage across concrete specimens, and SIX (6) sets of test cells for 4-inch diameter specimens with associated cables and accessories for accurate testing.

The Contractor shall provide equipment that meets all technical specifications identified below. All items must be new. Used or remanufactured equipment will not be considered for award.

Experimental, prototype, or custom items will not be considered. The use of “gray market” components are not authorized for sale in the U.S. by the Contractor is not acceptable. All line items shall be shipped in the original manufacturer’s packaging and include all original documentation and software, when applicable.

d. Include bolts and internal gaskets to fully seal specimen between Test Cells

e. Include temperature probe to measure solution temperature

IV. WARRANTY

The contractor shall warranty all products for a period of a minimum of 1 YEAR and the warranty shall be in accordance with terms in FAR 52.212-4.

V. DELIVERY TERMS

Delivery shall be F.O.B Destination and shall occur within twelve (12) weeks after contractor receipt of order in accordance with the table below.

FOB Destination means: The contractor shall pack and mark the shipment in conformance with carrier requirements, deliver the shipment in good order and condition to the point of delivery specified in the purchase order, be responsible for any loss of and/or damage to the goods occurring before receipt and acceptance of the shipment by the consignee at the delivery point specified in the purchase order; and pay all charges to the specified point of delivery. The contractor shall deliver all products to:

National Institute of Standards and Technology Shipping and Receiving 100 Bureau Drive, Building 301 Gaithersburg, MD 20899

Description Quantity or Format Due Date

Voltage Application and Data Acquisition System

ONE (1) No later than 12 weeks after receipt of order

Applied Voltage Test Cells SIX (6) No later than 12 weeks after receipt of order

VI. INSPECTION & ACCEPTANCE

In addition to the inspection and acceptance terms articulated in 52.212-4, the Government reserves the right to perform such performance tests and evaluations as defined below to verify product performance. Such tests and evaluations, if performed, shall be conducted within the environment that the system is to be operated. The Contractor has the right to be present during the tests and evaluations, if performed, at the Contractor’s expense.

Performance Tests:

1. Ensure that the equipment is operational and has no defects or missing parts.

NIST may choose at its discretion to forego this part of acceptance testing.

A visual inspection of the equipment will be performed by the NIST Subject Matter Expert (SME) to identify surface defects or any form of indication that any equipment was damaged during transport to NIST. The Government shall have sole discretion to require repair or replacement of damaged and/or nonconforming supplies at no cost to the Government. The Government at any time prior to acceptance shall reject the equipment due to defects and/or nonconformance. The vendor is responsible for latent defects discovered any time after final inspection. However, the extent of its liability shall be prorated over the useful life of the equipment.

Ownership of the equipment shall transfer to NIST upon acceptance by the Government.

The Government will test, inspect, and accept or reject the equipment within 5 business days of the receipt of the equipment unless otherwise indicated above. The Government reserves the right to conduct quality assurance testing to confirm that a given instrument(s) meets the manufacturer’s and/or the Government’s performance specifications. It is anticipated that the equipment will meet all manufacturer’s specifications and/or the Government’s performance specifications identified in the most recent operations and maintenance manual for each piece of equipment and/or in this document.

VII. PAYMENT SCHEDULE

Advance payment is not authorized. The Contractor must invoice in arrears according to the payment schedule. The Contractor shall be paid, in accordance with Net 30-day payment terms, upon receipt and acceptance of a proper invoice, in accordance with the following schedule:

1. 100% after acceptance by the SME, AND

2. After the successful completion of the testing requirements set forth in this document, AND

3. After receiving an invoice submitted properly, IAW the purchase order terms and conditions.

NOTE: Partial shipments and partial invoices will not be accepted, unless otherwise requested and accepted by the Contracting Officer prior to award offer. Proposed payment schedules shall be submitted with vendor’s response to the RFQ for consideration.
