SCADA_Sole_Source_Justification_Signed_K.Spolar.pdf

This is a Sole Source Request and Determination Form from the City of Gallup, New Mexico, involving a Water SCADA System Upgrade project with SKM Engineering. The project encompasses upgrading the existing supervisory control and data acquisition (SCADA) system for the City of Gallup's water infrastructure, including all materials, plant, equipment, and labor required. The proposed contract is for a 12-month term with a total value of $1,191,755.83 plus tax. The SCADA system upgrade includes providing a new server, workstations, tablets, networking hardware, radios, replacing obsolete PLCs and hardware, replacing existing IFIX and Historian Software, implementing VLAN fiber optic backbone with cellular redundancy, improving communication speeds, enabling remote system control, and enhancing security with dual-factor authentication.

SKM Engineering is being selected as the sole source contractor due to their extensive prior experience with the City of Gallup's water system, having installed and serviced the existing SCADA system since May 2007. The company has unique familiarity with the forty-one (41) water facilities, communication paths, and system components. The pricing is considered fair and in-line with similar SCADA work performed in northwest New Mexico and the Navajo Reservation, with the scope refined using input from DePauli Engineering and the City of Gallup. The sole source justification highlights potential cost and time efficiencies, including eliminating the need for radio and communication path studies, reducing site assessment costs, and providing a streamlined transition to the new SCADA system with shorter design and commissioning timelines.
