Folsom Dam Vessel Exclusion Barrier (VEB) and Debris Boom

Solicitation Number: 140R2026B0001

Pre-Bid Questions and Answers 1

Question 1: Does the BOR have a list of VEB systems that are certified to ASTM F2766?

Question 1 Response: No

Question 2: Is the Bureau of Rec requesting Evidence/Certification of testing prior to award?

Question 2 Response: Yes, see the revised section 35 79 30 requirements, with content requiring coordination with the COR for certification activities removed.

Question 3: Is the BOR only considering VEB that have already achieved certification of ASTM

F2766?

Question 3 Response: Yes, the New VEB shall all-ready be certified. See revised section 35 79

30, which requires NAVSEA certification or certification in accordance with ASTM F2766-11.

Question 4: Is the BOR willing to allow the certification process/timeline to be included in the procurement?

Question 4 Response: No, Reclamation does not plan to extend the offer due date of August 10, 2026, at 13:00 pm. Offerors shall provide this certification as part of their Offer in accordance with Section I, WBR 1452.237-80.

Question 5: Will the Bureau of Rec consider an equal or better alternative to the VEB at Folsom

Auxiliary Dam?

Question 5 Response: Yes, provided the VEB meets contract drawing, specification and certification requirements.

Question 6: Although computer simulation modeling is not listed in ASTM F2766 as a method of certification, it is accepted throughout the NAVSEA and DoN community for barrier testing.

Question 6 Response: See the response to Question 3.

Question 7: Timing of ASTM F2766-11 Certification Reference: Price Schedule CLIN 13 and

Section I (WBR 1452.237-80) Description: There is a contradiction regarding the timing of the barrier certification. CLIN 13 lists "Certification" as a post-award lump-sum pay item. However, Section I indicates that proof of ASTM F2766-11 certification must be provided "as part of any contractor proposal." Question: Please clarify if the physical crash-test certification must be fully completed and submitted with the pre-bid proposal, or if this is a post-award requirements implied by CLIN 13.

Question 7 Response: See the responses to Questions 2 and 3.

Question 8: Power Source for Warning Lights and Signage Reference: Price Schedule CLINs 11 and 12 Description: The solicitation requires 44 Warning Lights and 22 Warning Signage units, but does not provide an electrical infrastructure CLIN. Question: Are the warning lights and signage units assumed to be self-powered (e.g., solar or battery-operated)? If they require hardwired continuous shore power, will an electrical infrastructure/trenching CLIN be added to the schedule?

Question 8 Response: Refer to Specification Section 35 79 30 – 2.03 P and Q requirements.

Question 9: Missing Demolition and Salvage Ownership Instructions Reference: Price Schedule

CLIN 3 (Selective Site Demolition) Description: CLIN 3 requires the contractor to "remove and salvage part of the existing barrier." Question: Will the NDA-protected drawings explicitly distinguish which elements are to be removed versus salvaged? Furthermore, who assumes ownership of the salvaged materials (e.g., Owner-Retained vs. Contractor Disposal),and where on-site are salvaged items to be turned over?

Question 9 Response: Refer to Specification Section 02 41 13 – 1.02 A requirements.

Question 10: Pricing Allocation for Spare Module Hardware Reference: Price Schedule CLINs 7 and 10 Description: The solicitation requires the provision of spare connectors and "the required hardware for use." However, CLINs 7 and 10 only provide unit pricing for the parts themselves.

Question: Should the cost of the "required hardware for use" be distributed within the unit prices for the Spare Connectors (CLINs 7 and 10), or will a separate line item be created for the hardware?

Question 10 Response: Include hardware costs for Spare Module-to-Module connectors with

CLIN 7. Include hardware costs for the spare module with CLIN 10.

Question 11: Pricing for Clump Anchors and Buoys Reference: Brief Description of Work and

Price Schedule CLIN 9 Description: The Brief Description of Work requires "clump anchors, buoys and moorings," but the pricing schedule only includes a line item for "Moorings"(CLIN

9). Question: Should the costs for clump anchors and buoys be lumped into the CLIN

9"Moorings" price, or were line items for anchors and buoys inadvertently omitted?

Question 11 Response: Yes, refer to Specification Section 35 79 30 1.01 E requirements.

Question 12: Definition of Government Established Working Hours Reference: Site Access and

Deliveries Description: The IFB restricts personnel access and deliveries outside of the

Question 12 Response: See revised section 01 14 12 requirements.

Question 13: Clarification of Operations, Storage, and Parking Areas Reference: Price Schedule

CLIN 1 (Mobilization) and Site Security Requirements Description: The Site Security

Requirements severely restrict on-site parking and staging, but CLIN 1 requires pricing for

Mobilization and Preparatory Work. Question: Will the NDA-protected drawings include a designated site plan showing the allowable limits for contractor operations, material staging, and any permissible parking areas at the dam?

Question 13 Response: See Drawing sheet 485-208-60335 for Contractor Area of Use. Also, refer to Specifications Section 01 14 10 requirements.

Question 14: Project Plan Layout Dwg 60330 Sheet 4 shows the east end of the NEW VEB terminating in the area of the east buoy. The dwg also shows the existing barrier still in place and terminating at the same eastern buoy. Is this accurate?

Question 14 Response: Yes, both the existing barrier and the New VEB connect to the existing east flotation buoy. New Moorings shall support loads for the New VEB independent of the existing East Buoy mooring. See the revised section 35 79 30.

Question 15: Is the Bureau of Rec intending the contractor leave the east string of the existing

PSB 600in place?

Question 15 Response: Yes

Question 16: Is the new VEB plan to terminate at the shore near the rip rap or if not where does the Bureau of Rec intend to terminate the east end of the New VEB?

Question 16 Response: See the response to question 14.

Question 17: How will compliance with CUI Document requirements including CMMC, C3PAO and Level 2 self-assessment be confirmed?

Question 17 Response: The Non-disclosure Agreement identifies the specification and drawings as CUI. The CMMC, C3PAO and Level 2 Self-assessment do not apply to this project.

Questions 18: CUI document management requires strict safeguarding and distribution controls.

A major part of compliance as it relates to document management requires that documents are properly marked as CUI, including proper indicators on the CUI information. Please verify what parts of the specifications and drawings are considered CUI and re-issue the CUI documents with the correct markings and through proper channels.

Question 18 Response: The Non-disclosure Agreement identifies the entire specification and drawings as CUI.

Questions 19: CLIN Item 2 is for a Contract Documents Management System. Please describe how the Contract Document Management System will function with CUI Documentation, where

CUI Documents will be held if not with the Document Management system since it will not be a secure storage area, and how Bureau intends to communicate given CUI status.

Question 19 Response: CDMS security shall be in accordance with section 01 31 30, 1.05, D.

Question 20: Specification section 35 79 30, Part 2, Paragraph A states that the new system shall have a minimum design life of 50 years given proper maintenance. Manufactures would consider period replacement of wearing parts as portion of proper maintenance. Does the Bureau consider replacement of wear parts and pieces proper maintenance?

Question 20 Response: Yes, wearing parts shall last at-least 20 prior to requiring replacement.

See the revised section 35 79 30.

Question 21: Is it the Bureaus intent to match the existing auxiliary spillway barrier design so that parts and pieces are interchangeable between the two barriers / locations?

Question 21 Response: See the response to question 5.

Question 22: Drawings show moorings designed with chain and wire rope with contractors engineer to confirm compliance. Given the design life requirements, the entirety of the mooring system should be made with chain. If wire rope is allowed, the design life must include considerations that replacement of those components will be required. Please confirm wire rope is acceptable. If so, confirm that replacement is considered proper maintenance.

Question 22 Response: See the response to question 20.

Question 23: Please confirm Buy America requirements for all components, including chain.
