RFQ N3220522Q4082 - COMFORT Elevator Controllers Questions and Answers
1. Must our Naval Architect be a full-time employee, or may we hire one as a consultant on an as needed basis?
MSC Response: It is acceptable to hire one as a consultant as long as the offeror can submit a resume for the person they intend to hire as a consultant that shows they meet the qualifications in the RFQ.
2. To what extent does existing wiring of the old system need to be replaced?
MSC Response: All existing wiring/cables related to the elevator control system will be evaluated during the design shipcheck, and removed or replaced as necessary to fit the needs of the new design. Existing cables can be reused if feasible and if their condition is found to be acceptable.
3. For the elevator car remote IO communication is wireless acceptable using ABS approved 5GHz IWLAN RCOAX Cable and Antennas for those signals?
MSC Response: MSC prefers to hardwire connections and will not utilize any wireless emitting or receiving equipment due to the following:
1. This is a hospital ship with limited use of wireless communication for controls.
2. MSC does not desire to add additional issues with wireless security for the elevators.
3. The use of portable radios onboard could have interference between the radios and the elevators.
4. Are all limit and proximity switches going to be replaced on each elevator?
MSC Response: New limit and proximity switches or using existing will be based on the design provided from the contractor. If a proposal does utilize new limit and proximity probes the contractor will provide the reasoning (advantages) for new and a separate cost for the new limit and proximity switches as to evaluate against proposal that use existing limit and proximity switches.
5. Does the Navy want an HMI to be added to the car for maintenance diagnostics?
MSC Response: Please define what HMI would be added to the car? Would the HMI be for the car itself or for the controller? Would the HMI for the car rely on wireless communication?
Contractor Response: We are planning on having an HMI in the car for the purpose of troubleshooting and diagnostics only. If wireless is not acceptable, we would have the HMI hardwired.
MSC Response: MSC currently does not have a desire to add an HMI in the car; however, the contractor can provide the option to add an HMI in the cars, and provide reasoning (advantages) as to why it would be a cost-effective option to have it installed. MSC will then consider adding or declining the option as part of the design review process.
