About this file

Written by GovTribe AI ·

This document is a Performance-Based Work Statement (PWS) for a federal contract opportunity related to cosmogenic radionuclide analyses services.

The PWS outlines the USGS's requirement for a contractor to perform pretreatment and AMS dating of approximately 40 geologic samples, primarily focused on the 10Be isotope. The contractor will be responsible for crushing, grinding, and chemically preparing the samples, as well as providing the 10Be/Be ratios and associated laboratory errors in a spreadsheet format. The period of performance is from the date of award to April 30, 2025, with four option years subject to availability of funding. The place of performance is the contractor's facility, and there is no government-furnished property.

The related federal contract opportunity is a pre-solicitation seeking qualified businesses, under NAICS code 541380 (Testing Laboratory Analytical), to provide the required services in accordance with the PWS. Responses to the sources sought notice must be submitted via email by May 7, 2024. The government will not pay for any costs incurred in preparing the information.

PERFORMANCE-BASED WORK STATEMENT

I. GENERAL INFORMATION

A.Introduction
The USGS ESC has a requirement for cosmogenic radionuclide analyses services.
B.Scope.
The laboratory is to perform the pretreatment and will subcontract the AMS dating. The lab determines the content of a specific isotope in a geologic sample. The most common isotopes targeted are 10Be (Beryllium). This proposal envisions an ongoing contract to span 5 years.

II. WORK REQUIREMENTS

A. Technical Requirements.

1. Approximately 40 samples will be delivered to the laboratory.

2. The samples will be crushed and ground, quartz will be separated and purified, samples will be chemically prepared, and the resulting sample will be analyzed using AMS. The results will be provided to us in a simple spreadsheet, sent via email, and will include: Sample weight, information about standards used, 10Be/Be ratios, and laboratory errors.

3. Receipt of the above information will be the criteria for acceptance of the age-determination service.

B. Deliverables.

1.Spreadsheet as described above.
2.Delivery within one year of submission of samples.

III. SUPPORTING INFORMATION

A. Period of Performance: Date of Award to April 30, 2025 and four Option years subject to availability of funding and continuing needs.

B. Place of Performance: Contractor’s facility.

C. Government Furnished Property (GFP): None.

D. Special Considerations: None.
