Att-15 Current Conditions Photos.pdf

This document appears to be a set of current condition images for a Joliet VFD (Variable Frequency Drive) Replacement project, showcasing four contract line items (CLINs) with detailed photographic documentation:

CLIN 1 involves installing condensate pumps at air handlers, with images showing existing piping and pump infrastructure. CLIN 2 covers installing a domestic water make-up feed system, depicting pumps, control panels, and associated equipment. CLIN 3 focuses on replacing VFDs, with images of Square D electrical control panels, ABB VFDs, and associated electrical infrastructure marked with 10 HP and 25 HP ratings. CLIN 4 includes VAV (Variable Air Volume) installations, showing ductwork, control boxes, and mechanical system components. The project appears to be a comprehensive mechanical and electrical system upgrade, likely for a facility engineering improvement project, with detailed photographic evidence of the current system conditions prior to replacement or modification.
