RECOMMENDATION

title

Approve and authorize Sole Source Agreement No. 260225B with Siemens Industry Inc. for professional and technical support of the Siemens Desigo System at Napa County Jail for the term July 1, 2026 through June 30, 2030. (Fiscal Impact: $56,868 Expense, General Fund, Budgeted, Discretionary)

body

 

BACKGROUND

Approval of this agreement allows the County to have professional and technical support for the Siemens Desigo HVAC (Heating, Ventilation, and Air Conditioning) Management System (Siemens System). The Siemens System is a proprietary computer control system for HVAC management systems located at the Napa County Jail and other county facilities.

The vendor is sole sourced as they have full proprietary access to all legacy and modern software tools, firmware updates and factory support for the highly complex installation at the Jail. Corrections is requesting support for an existing operational environment in operation for 1.5 years and is aligning with Public Works' assessment of the vendor best suited to maintain that environment. Services with the vendor ensure continuity, compatibility, and reliable support of an established County system. These services are essential for the safe and consistent operation of HVAC equipment. Under the agreement, Siemens Industry will receive $40,230 for services rendered in the previous fiscal year. 

Requested Action:
Approve and authorize sole source Agreement No. 260225B with Siemens Industry Inc. for support of the Siemens Desigo System at Napa County Jail for the term July 1, 2026 through June 30, 2030, for a total contract maximum not to exceed $278,145.
