This addendum to Invitation to Bid No. RFB-45-25 is issued by the Commonwealth of Kentucky Department for Facilities and Support Services Division of Engineering and Contract Administration in coordination with the Kentucky Department of Corrections for the Water Tower Rehabilitation project at Kentucky State Penitentiary in Eddyville, Kentucky. The project involves the rehabilitation of a 300,000-gallon elevated water storage tank, including blast cleaning in accordance with SSPC SP 10 on interior and exterior surfaces, application of an SSPC Guide 6 Class III full containment system due to existing lead-based coating, various tank repairs, and repainting. Additional site work includes security fencing, sidewalks, utility pole relocation, and installation of temporary ground storage and emergency pumps. The work must commence as soon as possible after contract award, presumably early to mid-September, with substantial completion required within 120 calendar days from the date of the executed construction contract. The tank is located at 266 Water Street, Eddyville, Kentucky, and is an elevated legged tank style. Work hours are limited to 7:00 AM to 5:00 PM unless approved otherwise by the Warden, and the project is not subject to prevailing wage requirements. Mid-South Tank Consultants will serve as the inspector. All shop drawings must be submitted within 15 days of contract award, and all materials must be on-site before construction begins.
Bidders must provide a bid bond or certified check equal to not less than five percent of the lump sum base bid price. Liquidated damages are assessed at $750 per calendar day for delays beyond the substantial completion date and $450 per calendar day for delays beyond the final completion date. All contractors, employees, and subcontractors must undergo background checks and receive approval from the Warden prior to entry, complete PREA training on-site, and comply with strict institutional security rules including prohibitions on cell phones, weapons, illegal drugs, alcohol, tobacco, glass containers, and personal electronic devices on the yard area. An inventory of all tools must be made and inspected upon entrance and exit from the secure area. The contractor is responsible for providing temporary facilities including portable toilet facilities, temporary security fencing with razor wire, and new temporary utilities or coordination with the owner for existing utility connections. The project specifications include detailed requirements for gate valves, check valves, valve boxes, and tapping sleeves, with all materials and installation to comply with applicable AWWA standards and manufacturer recommendations.
