This is a service / maintenance or supply contract in Marshfield, Wisconsin. Contact the soliciting agency for additional information.

Questions and Answers: Q1: the configuration includes two combination cooler/freezer units, and some of the units appear to share a common wall. Additionally, there are questions regarding the flooring and structural components within the units. It is unclear whether the floor is insulated concrete or another type of flooring system, and clarification on the ceiling construction will also be needed to properly determine the scope of work. Given these observations, we want to ensure that the scope accurately reflects the work required before proceeding further. Could you please advise whether additional information, drawings, or clarification on the SOW will be provided regarding the cooler/freezer configuration, flooring, and ceiling construction A1: The units are Norlake enclosers see attached image, each is an independent insulated walk-in unit. Site visit date and time change due to weather issues. The new site visit date and time is scheduled for Wednesday March 18, 2026, at 10:00 AM CST. Please provide the names of the people requesting to attend along with the company which they represent to lynn.hults@usda.gov by 8:30 am on Wednesday March 18, 2026. Q&A's Q1 - What are the interior dimensions (length x width x height) of each walk-in freezer A1 - 10L x 9W x 9H See attached Photos. Q2 - What temperature setpoint is typically maintained for each freezer A2 - -20c range to be maintained -15C to -20C Q3 - Are there any ceiling obstructions (ductwork, piping, lighting, etc.) above the evaporator locations A3 - Yes, various items. Q4 - Could the facility provide the model numbers or nameplate photos of the existing condensing units and evaporators currently serving each freezer A4 - See attached photos Q5 - What refrigerant is currently used in the existing systems (for example R404A, R507, R448A, etc.) A5 - R404A Q6 - Where are the existing condensing units located (roof, outdoor pad, or indoor mechanical room) A6 - Indoor first floor are where the walk in are, the Condensers on and second floor. Q7 - If the condensers are located on the roof, will a crane be required for removal and installation, or is there a service elevator available A7 - The Condensers are inside the building on second floor no roof access required, or available. Q8 - What is the estimated distance from the evaporator location in each freezer to the condensing unit location A8 - Approximately 10-20 feet above. Q9 - Are existing roof or wall penetrations available for the refrigeration piping, or will new penetrations be required A9 - The current refrigeration line runs should be able to be refitted to accommodate new lines with limited modifications vendor to validate on site visit. Q10 - Are the walk-in freezers located on the ground floor of the building A10 - Yes, main hallway on ground floor. Q11 - If on an upper level, could you confirm the dimensions of the freight elevator to ensure safe transport of the replacement equipment A11 - No freight elevator available, a staircase is available to second floor special equipment may be required as to mounting new and removal of old. Q12 - Are floor drains available within approximately 5 feet of the freezer footprint for routing the evaporator condensate drain lines A12 - The drains are located directly in front of each unit existing drain lines may be refit to accommodate the new systems. Q13 - Can the facility confirm the existing electrical service available for the equipment (typically 208-230V, 3-phase for condensing units and 208-230V single-phase for evaporators) A13 - Yes, the current unit's power supplies are as listed, the vendor is to validate to new systems electrical requitements to existing supply Q14 - Should the contractor include new electrical disconnects and power circuits in the project scope, or will these be provided by the facility A14 - All electrical work to energize the new system is the responsibility of installer to set up if they determine that existing disconnects can be utilized to power new units that is fine. Q15 - Do the existing freezer systems connect to a building monitoring or alarm system A15 - No, there is a stand-alone cellular alarm system that will remain in place. Q16 - If so, will the replacement refrigeration controls need to interface with the existing monitoring system A16 - The controller will not be connected to alarm system Q17 - The Statement of Work indicates the freezers will be replaced one at a time to allow contents to be transferred between units. Once the first freezer is commissioned, how much time should be allowed for the facility team to relocate the stored samples before work begins on the second freezer A17 - This would only take about 30min-1hr to transfer the samples once the new system is operational and stable for at least 24hrs. Q18 - Would it be possible to schedule a brief site visit or virtual walkthrough with the facility maintenance staff prior to final quotation This project involves replacing equipment in walk-in freezers in accordance with the Statement of Work (SOW). Contractors are to submit quotations for the replacement of walk-in freezer equipment, and must review the SOW for detailed requirements and technical data. Bidders must provide a technical approach demonstrating their ability to meet all requirements, address the schedule requirements listed in the SOW, and explain any requirements they cannot accomplish. Pricing for all items must be submitted, and all quotations will be evaluated for technical merit, price reasonableness, and past performance. Small business concerns are encouraged to apply, and compliance with all applicable federal anti-discrimination laws and acquisition regulations is required. Offers must include adequate description and documentation of products, especially if proposing 'equal' products for any brand name or equal requirements.
