Sound Transit is soliciting quotes from qualified firms to provide a centralized Tridium Niagara system upgrade and software implementation for its parking garage Building Management Systems. The project aims to replace the current decentralized setup—where each garage operates independently—with a unified system that enables centralized account management and streamlined user access. The selected vendor will install and configure Niagara 4 Supervisor software, licensing, and a Microsoft SQL database, along with a graphical user interface that consolidates access to multiple sites. A key objective is to implement single sign-on functionality using SAML 2.0 integration with Active Directory, reducing user complexity and improving operational efficiency. The work will primarily be performed remotely and must be completed within 180 days of purchase order issuance. This procurement focuses on software deployment, system integration, and user interface development rather than construction or physical infrastructure.
