These Electric Dispersal Barriers protect the Great Lakes from the invasive species.*************REQUIRED CAPABILITIES*************The Contractor shall provide engineering and site verification; design submittals; fabrication; factory acceptance testing (FAT); operator and maintenance training during or immediately after FAT; technical documentation; packaging, transportation, delivery and unloading; and warranty coverage services in support of the areas specified in Program Background (above). Further details: a) Four 1.5 megawatt (MW) high voltage power supplies for Pulser 1 and Pulser 2 at Barriers IIA and IIB. and b) Two 350 kilowatt (kW) high voltage power supplies for Pulser 3 at Barriers IIA and IIB.*************Technical capability overview*************The replacement equipment will support existing pulse generating units and capacitor banks serving the electric dispersal barriers. The following summarizes the anticipated requirement for market research; it is not a complete fabrication specification.*************Input power: 480 volts AC, three-phase, 60 hertz.*************Output ratings: each 1.5 MW unit to provide 2,000 volts DC at 750 amperes and 2,200 volts DC at approximately 682 amperes, subject to its 1.5 MW continuous power limit. Each 350 kW unit to provide up to 1,000 volts DC at 350 amperes.*************Power conversion: copper-wound transformers and a 24-pulse silicon controlled rectifier (SCR) configuration, or an equivalent approach for Government consideration that achieves the required performance and harmonic reduction.*************Integration: compatibility with existing equipment spaces, access routes, electrical connections, cooling systems, and the Pulse Generating Control System. Identify any necessary changes to existing equipment or interfaces rather than assuming they are included in this procurement.*************Controls and safety: local and remote monitoring, communications, alarms, protective devices, and interlocks compatible with facility requirements. Existing interfaces include DeviceNet; the draft SOW also addresses Modbus TCP/IP.*************Operating conditions: continuous barrier service, compatibility with the pulsed load and existing capacitor banks, and the draft SOW ambient range of 0 to 50 degrees Celsius and up to 95 percent non-condensing relative humidity.*************Cooling and handling: demonstrate feasible heat rejection within available site cooling capacity and identify equipment dimensions, weights, lifting provisions, shipping configuration, and delivery/unloading needs. Early design submittals would establish dimensions, weights, anchorage, power and control connections, communications, cooling requirements, and heat loads in sufficient detail for USACE to develop the separate installation design while fabrication proceeds. Final deliverables would include drawings of the equipment as fabricated, Operation and Maintenance manuals, test reports, training materials, and storage/preservation instructions.***************************************If your organization has the potential capacity to perform this requirement, please provide the following information*************1) Organization name, address, email address, UEI and cage code, Web site address, telephone number, and size and type of ownership for the organization, and *************2) Tailored capability statements addressing the particulars of this effort, with appropriate documentation supporting claims of organizational and staff capability. If significant subcontracting or teaming is anticipated in order to deliver technical capability, organizations should address the administrative and management structure of such arrangements. Submit concise responses in the same organized format as below. Identify assumptions and distinguish firm capabilities from proposed alternatives. Partial responses from manufacturers or prospective subcontractors are welcome; clearly identify which portions your firm can support.**************************I. Interest and role Would your firm pursue this revised requirement as a prime contractor, manufacturer supplying a prime, distributor/integrator, or team member? Identify the intended manufacturer and major work allocations, if known. Explain any barriers to submitting an offer, including whether your response depends on finding a teaming partner.*************II. Relevant capability Provide up to three examples of comparable industrial HVPS or rectifier projects, including power/voltage ratings, application, approximate completion date, and your role. Describe experience with pulsed loads, copper-wound transformers, harmonic reduction, controls integration, and liquid cooling. *************III. Technical feasibility Identify requirements that would prevent participation, materially increase cost or lead time, or require an exception. Address the 24-pulse approach or proposed equivalent, output ratings, ambient conditions, cooling capacity and water quality, controls/protocol compatibility, physical fit, and any facility modifications. Describe the specific clarification or performance-based alternative recommended.*************Factory testing and training Describe available test facilities and a practical FAT approach for both ratings. Manufacturing and FAT would occur at the contractor/manufacturer facility. Distinguish full-power tests from separate full-voltage/full-current tests or simulations, and identify limitations in reproducing the installed pulsed load. Recommend measurable acceptance criteria and the equipment or site data needed. Confirm ability to train Government personnel during or immediately after FAT.*************IV. Schedule and capacity Provide a realistic schedule from award through design approval, long-lead procurement, fabrication, FAT, documentation, and delivery of all six units. State whether approximately 12 months is achievable, required Government review durations, current capacity constraints, and whether staggered deliveries would help.*************V. Payment milestones: USACE is considering an approximately 12-month period from award through delivery, subject to validation through market research. The proposed payment milestones are 25 percent upon preliminary design approval, 25 percent following successful FAT for all six units, and 50 percent upon delivery, unloading, Government receipt, and completion of required deliverables. Any financing, payment, inspection, and acceptance provisions will be established by the Contracting Officer in the solicitation. Would the proposed 25/25/50 payment structure support participation? If not, suggest practical milestones or financing arrangements, with approximate percentages and a brief…
