The Performance Work Statement outlines a project for replacing outdated Excel 5000 series controllers at B301, which are nearing the end of their service life and no longer maintainable due to obsolescence. The project aims to ensure the functionality of critical control systems operating HVAC and related components within the facility, as their failure creates delays and emergency repairs. The contractor is tasked with replacing the controllers with compatible Honeywell Tridium N4 products and updating the control system's programming and database. Key project requirements include full replacement and programming of the control systems, coordination with government representatives, ensuring compliance with cybersecurity standards, and conducting thorough testing and mechanical balancing of the HVAC systems. The contractor must also provide documentation, training, and an extended warranty while ensuring minimal disruption to existing facility operations. Additionally, any unidentified control systems or deficiencies must be reported for potential contractual modifications. The document reflects the government's commitment to maintaining efficient and secure facilities, central to mission-critical functions, within prescribed safety and compliance guidelines.
