About this file
This document is an Addendum (No. 4) for a VA Cincinnati Project (No. 539-21-108) to Remediate Temperature Controls, issued by Heapy (Project No. 2020-05099) on 01/12/2026. The addendum includes multiple specification and drawing modifications, primarily focused on HVAC and temperature control system updates.
Key changes include revisions to technical specifications across multiple sections, updates to infection control requirements, clarification on commissioning agent responsibilities (to be hired by the prime contractor), and numerous drawing modifications affecting Network Area Engine (NAE) devices. Specific drawing changes involve reusing or replacing various NAE components, adding a Tridium Building Control Router, modifying network VLAN assignments, revising scope of work notes, and eliminating certain equipment replacement requirements like air compressors and convector pneumatic controls. The addendum comprehensively addresses technical details for temperature control remediation at the VA Cincinnati facility.
