Inquiry #2: Reading the specifications for this project we have found that the control system -and ancillary components- are specified to only one supplier. This specification requires a single supplier for pump controllers (PLC's), the field instrumentation, (such as flow meters etc,) for fiber optic cables, and the cloud based monitoring system. This seems to be contrary to California Public Contracting Code, (PCC 3400) for specifying equipment which limits the ability for other manufacturers to compete for state contracts. Please advise if substitution for these single source products can be submitted which will provide the same functionality for the controllers, instrumentation, communications, and monitoring, as the sole source manufacturer?
