Renovation of a transportation facility in Sioux City, Iowa. Completed plans call for the renovation of a transportation facility.

The project is located at the Sioux Gateway Airport, 2403 Aviation Boulevard and includes the removal and replacement of rooftop units (RTU) 7, 8, and 9. RTU 8 and RTU 9 are to be upsized. Airflow on all three units is to be rebalanced in the spaces they serve. All three are served by hot water heating coils and will need to be re-piped. New temperature controls will be installed on all three units. Each bid must be made on a form furnished by the City and must be accompanied by a bid bond, a cashier's check or certified check of an Iowa bank or a bank chartered under the laws of the United States, or a certified share draft drawn on a credit union in Iowa or chartered under the laws of the United States, in an amount equal to ten percent (10%) of the amount of the bid, made payable to the City Treasurer of the City of Sioux City, Iowa. The check or draft may be cashed by the City Treasurer as liquidated damages in the event the successful bidder fails to enter into a contract within the ten (10) days after notice of award and post bond satisfactory to the City ensuring the faithful fulfillment of the contract.
