AI Contract Overview

This 8(a) set-aside forecast from Navfac Southeast involves the complete redesign and replacement of the HVAC system for building B-625B.

Key technical requirements include upgrading from a two-pipe to a four-pipe system, replacing all air handling units, installing a new DDC system with remote monitoring capabilities, and incorporating variable air volume boxes and fresh air make-up as needed. The scope of work includes replacing or cleaning ducting and ensuring that no exterior envelope penetrations are visible, suggesting the use of dormers for air intake. The contractor is responsible for the testing, balancing, and commissioning of the entire system. Additionally, the project requires strict safety precautions due to the anticipated presence of asbestos in the building's crawl space.
