The City of Ames Electric Services Department seeks an engineering consultant to replace three power-plant load centers and support bidding and construction.

The engineering-services quantity is 1; the design covers 3 load centers.
- **OEMs and systems identified:** **Federal Pacific** — existing breaker equipment being replaced; **Emerson Ovation** — plant DCS controls; **OSI monarch** — SCADA monitoring; and **SEL (Schweitzer Engineering Laboratories)** — desired products to maintain DCS and SCADA functionality. This is an engineering-services procurement, not a direct equipment purchase.
