KISD_BAS_Upgrades_2019_RFP_addendum_2.pdf

This is an addendum to a Request for Proposal issued by Kent Intermediate School District in Grand Rapids, Michigan for 2019 Building Automation System (BAS) upgrades. The addendum clarifies specifications for field controller licensing and device counts across twelve district facilities, including the Kent Career and Technical Center (KCTC), Kent Elementary Complex (KEC), Kent Technical Center (KTC), Maintenance Building, and other named buildings. The project encompasses upgrades to existing Building Automation Systems utilizing Tridium Niagara platforms (versions 3.8.38 through 3.8.41.2) with communication protocols including N2, Modbus, and BACnet networks. The district is requesting an FX-80 license upgrade to accommodate an additional 21 field controllers planned for implementation in the coming months. The specification details identify 12 distinct BAS locations with varying device counts ranging from 6 devices at the Maintenance Building to 85 devices at KCTC_FX60, totaling approximately 571 devices across all systems.

The addendum indicates that Mayfield, an existing system component, will be expanded with the additional 21 controllers, necessitating enhanced licensing capacity on the FX-80 platform. The document provides detailed technical configurations for each building's existing controllers, including current model designations, Tridium Baja versions, bus information, and device quantities organized in a comprehensive specification table. Notable configuration details include KCTC as the only facility with two Jace units and multiple network buses (N2-A through N2-D plus N2-XP), while Oakleigh (OAK) is noted as not yet connected to the BAS network but will be integrated as the project progresses. The specifications reference existing JCI controllers (FX-60, FX-70, FX-20 models) and third-party equipment including Distech controls at the Oakleigh facility.
