S6.04- Glass Block Frames.PDF

Based on the provided information, there appears to be a discrepancy. The file named "S6.04- Glass Block Frames.PDF" does not seem to be related to the state and local contract opportunity for the Lafayette Public Library Rooftop Unit Replacement. The contract opportunity description suggests a project involving HVAC equipment replacement for a library in Colorado, while the filename suggests a document about glass block frames. Without the actual contents of the PDF file, I cannot provide a detailed summary. To proceed with an accurate summary, the actual contents of the "S6.04- Glass Block Frames.PDF" file would need to be shared and reviewed.
