5. Construction of improvements, including structural, mechanical, HVAC, plumbing, electrical, and fire sprinkler systems.

Selection as a prequalified Contractor does not imply Owner's acceptance or approval of the Contractor's specific personnel, equipment or methods, whether or not these items are described in the Contractor's prequalification statement.

Statements of Qualification are to be received at the Caldwell Engineering Department located at 621 Cleveland Blvd , no later than Tuesday, May 12, 2026 , 3:00 pm local time.

The City of Caldwell reserves the right to reject any and all Consultants, to waive any irregularities in the Statements of Qualification received, and to accept the Consultants for roster that are in the best interest of the City.
