3389 Large Class Hopper Dredge (LCHD-ESS)

• Proposal page count: All submitted pages count, except past-performance questionnaires, CPARS records, the Preliminary Design Report, commitment and teaming letters/agreements, and catalog cut sheets. The Summary Section is not exempt.
• Cybersecurity: USACE confirmed CMMC Level 2 (Self) is required for systems handling FCI or CUI during the contract.
• Pricing format: Excel is required only for price-breakdown information supporting EPA documentation—not for every Section B price breakdown.
• Cyber Resilience classification: The Section H drawings/documents for the ABS Cyber Resilience notation must go to both the Government and ABS for review and approval. USACE will correct the duplicate drawing number, add the CR notation to Section C, and list deliverables in C004.
• Dredging performance assumptions: For material properties, use the Overall Average grain-size distribution for Columbia River Mile 03–103 in the cited soil-classification document (page 9). Loading-time analysis must account for draft changing from hopper-empty to 6,500 cubic yards of 1.8-SG material.
• Station-keeping and pipeline operation: Questions about holding position in cross-currents and orienting with the current are referred to C002 clarifications and modifications; the response excerpt does not state the exact revised operating criteria. Applicants should check revised C002 before selecting thruster arrangements.

Amendment 002 added detailed technical specifications and operational requirements for the Large Class Hopper Dredge replacement vessel, including capacity, propulsion system, Jones Act compliance, and mission parameters.
