STATEMENT OF WORK

1 - Background

NASA-GSFC operates and maintains a semiconductor facility located at the Greenbelt campus in B30. The Detector Development Laboratory is a cleanroom Class ISO 4 (formally Class 10), that is critical for the research, development and fabrication of detectors expanding various wavelengths, for space applications and sensors for high atmospheric measurements.

The high purity water systems are essential for these facilities, and they are also critical for the uninterrupted daily operation of the laboratories.

The reason to establish this contract is to maintain the performance of the systems to accomplish the mission of the Detector Systems Branch, which is to provide R&D and fabrication of detectors for scientific community. This activity supports several research and flight projects, which are dependent on detectors and devices fabricated in this facility.

2 - Objective

This Statement of Work is to establish a preventive maintenance agreement for one year for the high purity water systems located in B11-Room S13A, B-11-room S-340, B30-DDL main system and a small system used for the make up for the process chilled water system. These systems are part of the infrastructure support for the semiconductor fabrication facility and other laboratories under the ownership of code 553. The contractor must maintain all components of the system that include: pre-filters, water softener, carbon filters, final cartridge filters, reverse osmosis membranes, ultraviolet units, mixed bed deionization units, ultra filtration modules, water pumps, system sanitation, and related components of the systems.

3 - Period of Performance

The period of performance shall start on September 8, 2022 and cover one year of parts and services until September 7, 2023.

4 – Components of the system in B11 S 13A

W3T332785 Reverse Osmosis System Function: Reduction of TDS and Organics A single pass reverse osmosis system typically removes 97% of the total dissolved solids (TDS) and 95% of naturally occurring organics.
