About this file
This is Addendum #5 to an Invitation to Bid (ITB) issued by the City of Ocala Water Resources Department (Marion County, Florida) for the procurement and turnkey installation of a rotary press dewatering system at Water Reclamation Facility #2. The project requires vendors to supply a complete rotary press unit with support frame, variable frequency drive motor, wash assembly, polymer mixing system, control panel, and instrumentation capable of treating biosolids sludge to a minimum of 16 percent total cake solids. The mandatory pre-bid meeting was held on March 19, 2026, at 11:00 AM at the WRF #2 facility located at 4200 SE 24th Street, Ocala, Florida 34471, with bid submission deadline of April 8, 2026. The project requires substantial completion within 182 days from the Notice to Proceed date, followed by an additional 30 days for final completion, with a three-year warranty on materials and labor.
Addendum #5 clarifies critical scope items through questions and answers addressing control panel integration, electrical work responsibilities, testing requirements, insurance, liquidated damages, and site logistics. The City will provide integration assistance but not full installation; the City will perform all electrical work in-house once equipment specifications and power requirements are received, including provision of power to the Variable Frequency Drive. Liquidated damages are set at $100 per calendar day. Standard electrical testing procedures including insulation resistance testing (megging) and routine verification tests are required prior to startup. Builder's Risk insurance is not required, and there is no retainage on the project. The City will remove and reinstall the hand railing system, while the contractor may remove and must reinstall side panels and roofing panels as necessary to facilitate equipment installation. The contractor is responsible for at least 80 percent of all work and must secure all required permits.

SECTION 1. QUESTIONS AND ANSWERS
1.1 QUESTION: The project summary says that monitoring instrumentation and flowmeters will be required. Please confirm what monitoring instruments or flow meters are required, which are not included in the rotary press equipment.
ANSWER: The project summary is referring to the control panel for the new equipment for the monitoring instrumentation, and if there are any flowmeters required in addition to the existing sludge flow meter in place.
1.2 QUESTION: Will the new control panel need to be tied into an existing PLC? If so, which PLC will it need to be connected to?
ANSWER: Communication or other type of controls need to be established to be able to operate sludge pump and polymer system that are operated from a different PLC. Keep in mind we also operated the centrifuge that utilizes the same sludge pump.
1.3 QUESTION: In Addendum #3, it was said that the City of Ocala will assist with integration. Please confirm what level of assistance the City will provide. Will the City integrate the new system with their existing SCADA system? Will the City modify any HMI screens as needed?
ANSWER: The City will assist with integration. We will not do a full installation.
1.4 QUESTION: In Addendum #3, it was said that the City will handle the electrical work to bring power to the new fan press. Please confirm the extent of the electrical scope that the City will perform.
Will the City install all raceways, junction boxes, disconnect switches, and panels? Will the City connect power to the new control panel and from the VFD to the pump?
ANSWER: Once we receive the necessary specifications and power requirements for the machine, the electrical work will be performed in-house by the City. This also includes providing power to the VFD. This is why the scope specifies that the unit must be compatible with Yaskawa Variable Frequency Drives and
Siemens Programmable Logic Controllers
1.5 QUESTION: Please list any electrical testing or studies that are required, if any?
ANSWER: The project will require standard electrical testing procedures, including insulation resistance testing (megging) and other routine verification tests typically performed for equipment installation and commissioning.
