DESCRIPTION

The government authority in Thornton, Colorado, is seeking professional engineering services to replace an existing headgate and provide automated flow control using a solar-powered actuator connected to the existing downstream flume flow meter. The consultant will evaluate the existing ditch structure and channel conditions to determine the appropriate configuration, installation method, support requirements, and integration approach for the new gate system.

The scope includes evaluating and designing the electrical, instrumentation, and control components needed for automated operation. This includes the solar power supply, wiring, conduit, actuator sizing, control logic, communications, fail-safe operation, manual override capability, and integration with the existing Parshall flume flow meter and monitoring infrastructure. The consultant will also design all necessary supports, anchorage, fastening, mounting, and structural modifications.

The consultant must prepare complete design documents for a functional system incorporating civil, structural, mechanical, electrical, instrumentation, and controls components as required. A mandatory pre-bid conference is scheduled for October 13, 2026, questions are due by October 26, 2026, and the contract period will be one year.
