Outdoor Emergency Warning Siren

The City of Bloomington, Illinois, is soliciting bids for the furnishing and installation of two new outdoor emergency warning sirens, replacing existing units at Pepper Ridge Elementary School and 614 IAA Drive, with full removal of the old sirens and associated concrete pads. The required equipment is the American Signal Corporation Tempest Model T-128 operating on DC or an approved equivalent, with a minimum one-mile radius, 128dCB sound output at 100 feet, adjustable rotation of 2 to 6 rpm, and a three-minute standard signal duration, mounted at least 50 feet above ground using existing electrical service. Activation must be compatible with the Motorola XPR5380e radio in analog mode and controlled via CompuLert software with a UL-listed magnetic starter in a fiberglass NEMA enclosure. Bids must be submitted electronically via OpenGov by August 25, 2026, and include a hard copy of the bid guarantee for review by the Finance Department. The project must be completed by April 30, 2027, with all work performed in compliance with federal, state, and local regulations including the Illinois Prevailing Wage Act and Employment of Illinois Workers on Public Works Act, requiring certified payroll submissions monthly. Bids over $10,000 require a bid guaranty of at least ten percent, acceptable via cashier’s check, money order, certified bank check, or surety bond, with performance and payment bonds at 100% of the contract value due within ten business days of award. The City applies net 45-day payment terms after invoice receipt or final acceptance, contingent on inspection and satisfaction. Contractors must carry comprehensive insurance coverage including $2 million general liability, $5 million umbrella, $1 million workers’ compensation, and $2 million automobile liability, and must indemnify the City from liability. Local bidders may receive a preferential discount of up to five percent on bids between $10,000 and $50,000, scaling down to a flat $50,000 discount on bids exceeding $1 million, provided they certify as a local consultant. Bidders must comply with strict submission protocols, including uploading a single PDF of certifications, completing the Contract Diversity Goal Form and Equal Opportunity Plan, registering as a contractor if performing regulated trades, and participating in approved apprenticeship programs if the bid exceeds $100,000.
