IT network modernization

The Des Moines Area Regional Transit Authority (DART) is seeking proposals for a comprehensive IT network modernization project spanning Polk County and Des Moines City, Iowa. The procurement focuses on a phased infrastructure upgrade involving core network updates, implementation of a software-defined wide area network (SD-WAN) architecture, and enabling connectivity for a future third facility. Phase 1 will specifically migrate two existing sites (Cherry Street and Dart Way) to SD-WAN while integrating a new third site, with Dart Way eventually being decommissioned. Key deliverables include hardware upgrades such as firewalls, core switches, optional SD-WAN edge devices, and wireless access points, along with associated licensing and professional services for installation and configuration. Evaluation criteria will likely emphasize technical capabilities, vendor experience with SD-WAN implementations, and comprehensive network design that supports DART's current infrastructure, which includes multiple internet service providers, complex VLAN configurations, and requirements for VPN access, 802.1x authentication, and deep packet inspection.

The solicitation does not explicitly mention set-aside designations or restrictions on respondent types. The current network infrastructure involves multiple internet service providers including MCHSI, Lumen, CenturyLink, and Verizon, with existing redundant connectivity and segmented network zones for security compliance. DART is finalizing contracts for new dual 1Gbps diverse internet circuits, which vendors should not include in their proposals. The project is structured across two phases, with Phase 1 focusing on core infrastructure and Phase 2 potentially expanding to access layer components, suggesting a total investment potentially ranging from $250,000 to $500,000. The procurement allows for flexibility in implementation, with optional components like SD-WAN edge devices and wireless access controllers. Vendors will be expected to provide a comprehensive solution that integrates with DART's existing network topology, supports approximately 10-15 concurrent VPN users, and enables future scalability and technological advancement.
