Contractors must demonstrate five years of corporate experience specifically in greenhouse control work and provide references for similar projects, along with satisfactory or neutral past performance ratings. The government will use a Lowest Price Technically Acceptable (LPTA) evaluation approach, assessing technical capability, past performance, and price. A mandatory site visit is scheduled for August 28, 2025, with quote submissions due by September 4, 2025 at 1:00 p.m. Central Time.

The project includes a base bid for control system replacement and three optional bids covering various heating unit replacements across the facility's four greenhouse bays and headhouse areas.
