SUMMARY OF CHANGES
SECTION SF 30 - BLOCK 14 CONTINUATION PAGE
The following have been added by full text:
AMENDMENT 4
RFI Group 4
86. Solicitation section C335 states in part "The hopper shall be open at the top with coamings all around and with 5-foot (1.5m) high splash screens over the full length." Will the government confirm please whether the splash screens are in addition to a coaming of un-specified height, or whether the splash screens and the coaming are considered one and the same?
a. USACE Response: Splash screens are not considered the same as the coaming.
Splash screens shall be provided as necessary to prevent dredged material to splash back onto the deck during hopper loading. Please see revised Contract Paragraph C335 for clarified requirements.
87. The Solicitation appears to be silent with regard to whether or not the hopper total volume may include volumes encompassed by the coaming above the deck level. Can the total hopper capacity include such volumes into a portion of the coaming height, limited by the overflow height?
a. USACE Response: Coaming height may be used in determination of total hopper capacity so long as coaming structure is designed for hopper fill and slurry water loads. Coaming height above the maximum hopper fill level shall be provided as required to manage slurry water flow through the overflow.
88. C604 SPECIFIC REQURIEMENT requires EALs in the thruster pod. C620 does not require EALs for the bow thruster. Per the EPA's Vessel General Permit, 2013 (VGP13), EALs are only required for oil-to-sea interfaces. Many propulsion OEMs have different solutions for VGP13 that allow mineral oils in the pods. Are VGP13 compliant seal arrangements acceptable or must Z/L-drive thrusters use EALs?
a. USACE Response: EALs shall be required for any oil-to-sea interfaces per the referenced EPA General Permit, 2013. EALs may be omitted if thruster pods are equipped with alternative seal systems (e.g. “air seals” or void space double seals) that are compliant with EPA Vessel General Permit 2013. Please see revised Contract Paragraph C604 and C620 for clarified requirements.
89. 52.211-8 Time of Delivery (Jun 1997) starting on page 436 of 470 indicates a rigid delivery schedule at 1,555 days of the contract award Notice to Proceed. The required delivery schedule reflecting the duration for each of the 4 phases is identified and while there is an alternate Offerer’s Proposed Delivery Schedule, it is limited to only an accelerated delivery schedule and specifically indicates:
a. “Offers that propose delivery that will not clearly fall within the applicable required delivery period above, will be considered non-responsive and rejected”
b. Having extensive experience with vessels of this size and complexity, it is strongly opined that 24 months (730 calendar days) is too short a duration for the Phase III Construct and Test period for the MCHD. A reasonable construct/test period for a vessel of this size/complexity is firmly in the 30 – 34 month range.
The USACE has placed a significant risk on the Prime Contractor to agree to an unrealistic delivery schedule are otherwise forfeit considerations as “non-responsive and rejected”. QUESTION: Will USACE consider extending the Required Delivery Schedule for Phase III (Construct and Test) to 34 months (preferred) or at least to 30 months (minimum)?
c. USACE Response: This Solicitation allows for construction and procurement of long lead-time items prior to completion of the engineering phase. Provisions are included in Contract Paragraphs H01 and H08. The requested duration of 30-34 months of construction is possible based upon the provisions to allow construction to start during the 18-month long Engineering Phase, provided that the requirements of Contract Paragraph H01 are met.
90. Section F (page 357 of 470) appears to be missing subsections F01 and F02. Section H01.E Phase Sequencing references Section F and specifically notes periods of performance defined in Contract Paragraph F02 which does not exists. QUESTION: Please confirm if there is missing paragraphs/information in Section F.
a. USACE Response: Contract Paragraphs F01 and F02 were not used in this solicitation. Please see revised Contract Paragraph H01 with corrected reference.
91. The RFP is due 18 October 2022 (1500 eastern). Having detailed the proposal design timeline synchronized with pricing specification/estimate timeline, it is contended that the Oct 18th due date is too aggressive with which to finalize a proposal at the proper level of detail and accuracy. QUESTION: Will USACE consider extending the RFP due date roughly 3 weeks to 10 November 2022?
a. USACE Response: Receipt of proposals have been extended until 10 November 2022 0300 PM EST. The cutoff date for the receipt of RFIs will be 45 days prior to the closing of the Request for Proposal, currently 26 September 2022. Upon receipt of additional RFIs the Government will consider any further extension.
C335 HOPPER STRUCTURE
GENERAL DESCRIPTION
The capacity of the hopper shall be in accordance with the requirements specified in Contract Paragraph C002.
REQUIREMENTS
The hopper geometry shall promote optimal settling and dumping of the dredged material.
The hopper capacity to the maximum hopper overflow level shall be 6,000 Cubic Yards. The API certified hopper capacity tables (Sect. C604) shall be utilized to set the maximum travel on the hopper overflow at height corresponding to 6,000 Cubic Yard capacity.
The hopper shall be open at the top with coamings all around and with 5-foot (1.5m) high splash screens as necessary to prevent dredged material to splash onto deck during hopper loading, in particular around distribution system points over the full length. The splash screens are not to be considered for strength of the hull midship section. At the ends of the hopper the splash screens shall be of increased height to prevent splashing and spilling during loading as the ship pitches.
The hopper plating shall be inclined towards the bottom doors to promote discharge of the dredged material. As much as possible, the hopper shall be free from obstacles that may disturb the longitudinal flow of the dredged material.
The hopper shall be designed for multiple methods of emptying dredged material. The hopper shall be capable of discharging dredged material through hydraulically operated bottom doors (see Contract Paragraph C514). Alternatively, the hopper can be discharged via the HOPPER COLLECTION SYSTEM (See Contract Paragraph C520). If the HOPPER COLLECTION SYSTEM includes a self-emptying channel as an integral part of the hopper structure, the global strengths properties of the Midship Section (See Contract Paragraph C300) shall be assessed both including and excluding the contribution of the material of the self-emptying channel.
The Contractor is to develop drawing 849-C335-01 HOPPER STRUCTURE and submit to the COR and ABS for approval.
SPECIFIC REQUIREMENTS
The Contractor shall specify the required wear allowances for the hopper structure. Wear allowance shall be based on the estimated lifetime, material chosen, and the type of dredge materials as described in Contract Paragraph C002. The hopper plating wear allowance calculations shall be included in the Lifetime Calculation as specified in Contract Paragraph C502.
Due care shall be taken to provide structural continuity at the forward and aft ends of the hopper structure to cope with the change in vessel cross section. Adequate structural transitions are to be provided for introduction of global hull loads into the hopper structure and vice versa. The hopper structure and its integration into the hull structure shall be part of the global FEA model Top and bottom openings in the hopper structure shall be fitted with corner reinforcements if and as necessary.
If a self‐emptying channel is selected, additional wear resistance shall be provided over the complete surface in contact with the dredged material, either by increased wear allowance on the structural plating or by lining with wear resistant cladding plate of increased hardness.
A catwalk shall be arranged above the hopper to handle the locking mechanism of the bottom doors. Platforms for safe access to gantries and walkways to the dredge valves above the hopper shall be installed. Platforms and catwalks shall be in accordance with the requirements of Contract Paragraph C425. This catwalk may interface with those required by Contract Paragraph C512.
SPECIAL FEATURES
None.
