Please note: This is a Sole Source Notification. Specifications include, but are not limited to: Oregon State University intends to contract for the provision of an upgrade to pieces of our existing Particle Image Velocimetry (PIV) equipment suite from LaVision as a sole source not based on the uniqueness of the product, but rather on its ability to meet compatibility requirements of an existing line of equipment. An upgrade to a piece of our existing PIV equipment suite that was originally manufactured and installed by LaVision will enable higher speed stereoscopic PIV measurements of two-phase coolant flow rates to a boiling surface, and is uniquely equipped to ensure that upgrades to the existing pieces of our LaVision equipment suite are done with minimal integration. An entity may appeal this determination in accordance with OSU Standard 03-010. Section 5.17 no later than the closing date indicated on the website.
