Performance Work Statement

A. Introduction

The U.S. Geological Survey (USGS) on behalf of the U.S. National Science Foundation (NSF) manages the NSF Ice Core Facility (NSF-ICF). This facility is located on the north side of E Bay, building 810, on the Denver Federal Center, Denver, Colorado.

The NSF-ICF has a requirement for operations and maintenance (O&M) services of a newly constructed CO2 refrigeration plant and all associated subsystems.

The NSF-ICF CO2 refrigeration plant and associated subsystems was commissioned on July 3rd 2025, followed by a nine-month run-in period. From April 2026 to June 2026 ice cores were moved from the old facility to the new NSF-ICF.

B. Background

The NSF-ICF CO2 refrigeration plant is a highly specialized facility in Denver, CO. It stores over 30,000 meters of ice cores that have been drilled from the world’s ice-covered regions for scientific investigation of the Earth’s past climate and atmosphere. To date, the cost of acquiring the samples stored in the NSF-ICF CO2 refrigeration plant is approximately $750M. Due to lack of accessibility to collection sites and the high cost of redrilling, recollection of many of these cores is impossible. The ice core samples must be stored at temperatures well below freezing (- 34C) and within a narrow temperature range to maintain sample integrity. It is not enough that the cores be prevented from melting, if the stored samples warm to approach the freezing point, components of the old air and other trapped substances in the ice may migrate out of the ice destroying the scientific integrity of the ice and rendering the samples useless. In addition, if the temperatures vary too much, even within a range of subfreezing temperatures, the ice can undergo disastrous structural and chemical changes, again affecting the scientific integrity of the samples.

C. Scope

The NSF-ICF CO2 refrigeration plant is an extremely complicated and custom facility utilizing new trans critical CO2 technology and numerous associated controls and supporting subsystems.

The Operations and Maintenance (O&M) Contractor shall provide all materials, supervision, labor, tools, equipment, technical recommendations and travel necessary to accomplish on-site preventative maintenance, regular maintenance, and emergency response services for the NSF- ICF CO2 refrigeration plant and associated subsystems.

The Contractor shall source and procure appropriate replacement parts necessary to conduct repairs. Invoices shall be submitted by the Contractor monthly in arrears. Repair or replacement parts, all billable supplies, and labor shall be invoiced separately. Parts and supplies shall be identified, and their acquisition shall be approved by the on-site NSF-ICF Technical Curator or USGS Program Coordinator via e-mail confirmation prior to procurement.

D. General Requirements

The NSF-ICF CO2 refrigeration plant and associated subsystems is required to always be operational, to have all systems and subsystems be fully functional, and to operate within the prescribed temperature specifications required by the NSF-ICF.

The NSF-ICF CO2 refrigeration plant must be serviced and repaired by qualified technicians trained specifically on CO2 (R477) refrigeration systems with the ability to procure and identify the parts necessary for quick repairs and be on site as needed to perform the service or repair.

Refrigeration equipment must be repaired as soon as possible (see table for response times in Section E.5 EMERGENCY RESPONSE SERVICES) after a failure or during regularly scheduled maintenance to limit down time. In addition, the O&M Contractor must perform necessary repairs based on procedures described in the CAR 112E Installation and Operation Manual, technical expertise, or training received from the installation contractor. The O&M Contractor must maintain a spare parts inventory for prompt repairs.

Due to the complexity of the NSF-ICF CO2 refrigeration plant, the O&M Contractor shall meet monthly (formally or informally on site) with the NSF-ICF Curators to review system operations.

Meetings are to ensure the NSF-ICF Curator is aware of any operations that fall outside the technical specifications described in the CAR 112E Installation and Operation Manual such as CO2 refrigeration plant issues, operational inconsistencies, and negative trends in CO2 refrigeration plant over time.

All work performed under this contract shall be subject to review by the NSF-ICF Technical Curator and USGS Program Coordinator. Work not compliant with manufacturer technical specifications shall be corrected at no additional cost to the U.S. Government.

All work performed under this contract shall be subject to applicable local, state, and federal codes and regulations in force at the time the work is completed.

All work performed under this contract shall take place at the NSF Ice Core Facility located on the north side of E Bay, building 810, on the Denver Federal Center, Denver, Colorado.

The NSF-ICF maintains refrigeration using a M&M Carnot trans critical CO2 refrigeration system (CO2 system). The CO2 system ensures temperatures remain within technical operating requirements, so the integrity of ice core samples is preserved. A description of the system, as well as the technical operating requirements and associated required O&M Contractor activities, are described in the following sections.

D.1 System Description

The CO2 system consists of the following major components:

• Two sets of Transcritical CO2 compressor racks

• Two Gas coolers/condensers

• 8 Evaporators

• Flash gas bypass system

• High-pressure controls and valves

• Heat reclaim system for hydronic floor application

• Electronic expansion valves

• System controllers and automation

• Safety systems and pressure relief devices

• CO2 leak detection system

The CO2 system includes an integrated hydronic floor system. The hydronic floor system covers approximately 6000 square feet divided into 24 independently controlled zones. The hydronic floor system consists of the following major components:

• Heat exchanger interface with the CO2 system

• Primary and secondary circulation pumps
