Warning Sirens Inspection and Maintenance

Kenosha County Purchasing Division is issuing a Request for Bid (RFB) to establish a contract for comprehensive inspection and maintenance services of the County's emergency warning siren system comprising 35 warning sirens located throughout Kenosha County and surrounding municipalities. The scope of work includes inspections scheduled on an 18-month cycle with services beginning April 1, 2027, and continuing through October 2031, with subsequent inspections scheduled for October 2028, April 2030, and October 2031. Bidders must provide fixed unit prices for each of the 35 siren locations covering four inspections over the entire contract period, with all inspection costs including labor, fuel, equipment, materials, tools, and vehicles, and no fuel surcharges permitted. Inspection services must meet or exceed manufacturer recommendations and include motor contact inspection, oil changes, chain and belt lubrication, control cabinet cleaning, battery testing and replacement, signal verification, and structural assessment of siren poles and mounting brackets. Contractors must also submit informational pricing for on-call maintenance and repair services with a maximum 72-hour response time, including hourly labor rates, travel time estimates, material costs, and miscellaneous charges. Qualified bidders must have at least five years of experience in siren inspection and maintenance, provide three references for similar services completed within the past five years, and submit vendor responsibility forms by April 24, 2026, with bids due by 1:00 PM on April 29, 2026. A pre-bid conference is scheduled for April 14, 2026, at 2:00 PM at the Kenosha County Administration Building, with contract award estimated for May 13, 2026, and the award will be made to the lowest responsive, responsible bidder meeting all specifications.

The solicitation requires bid and performance bonds with a five percent bid bond based on total bid price and a performance and payment bond for 100 percent of the contract price, and contractors must maintain comprehensive insurance including Commercial General Liability ($1,000,000 per occurrence/$2,000,000 aggregate), Automobile Liability ($1,000,000 combined single limit), Workers Compensation at statutory limits, and Excess/Umbrella Liability ($1,000,000). The bidding documents do not indicate set-aside designations for disadvantaged enterprises or restrictions limiting competition to specific organization types; however, all respondents must complete the Vendor Responsibility Questionnaire for Public Work Construction Projects, which requires notarized certification of accurate responses and disclosure of business entity information, ownership details, five-year employment history, professional licenses and certifications, legal history, financial capacity and bonding limits, and current participation in Department of Labor or Wisconsin-approved apprenticeship programs. No incumbent vendors or existing contractor information is specified in the procurement documents. The solicitation does not provide an explicit budget range or award value; however, the contract structure establishing fixed prices for four inspections of 35 siren locations over approximately four and a half years, combined with the requirement for informational on-call maintenance and repair pricing, suggests evaluation will focus on the contractor's comprehensive pricing for both scheduled inspections and emergency services. A one-year warranty on defective workmanship and materials is required in addition to manufacturer warranties, and the contract may be extended by mutual agreement beyond the October 2031 completion date.
