The rest of the security fence is to be grounded if necessary per Chapter 2 of the “Force Prot Physical Security ATFP CIM_5330_1C” document.

21. Will existing floating dock still be used once the WLB Wharf is constructed? Seems it will be “locked in” by the Approach Pier.

Answer: The existing floating dock will remain in use if bid Option Item 3 is not awarded.

If bid Option Item 3 is awarded, the existing floating dock will remain, but it will no longer be in use. See revised Appendix A, Sheet C1 in this amendment for additional clarification.

28. Are there any designated areas where floating equipment, such as floating cranes and barges, be stored when not performing work.

Answer: There are no designated areas. The US Coast Guard will allow floating construction equipment to be stored between the existing wharf and the north end of the cove, as long as it does not project beyond the outboard face alignment of the existing wharf (which would impede the channel width). Stored floating equipment shall also maintain a 50' clearance from the Bouy Tender when it is berthed and a 30' wide clearance for US Coast Guard small boats between small boat floating dock and the main channel.

After award, the Contractor is to coordinate with the local operational US Coast Guard units if additional space is temporarily necessary.

29. What are the limits of work on the water side for operation of floating equipment.

Answer: Contractor shall limit the intrusion of his floating equipment to 120’ or less into the channel, as measured from the outboard face of the new wharf and float alignment. Floating equipment which extends more than 60’ into the channel from the face of the new wharf and float alignment must have navigation lights and be actively manned.

After award, the Contractor is to coordinate with the local operational US Coast Guard units if additional space is temporarily necessary.

30. Are there standoff distances that must be maintained while WLB and small boats are present at berth or loading and unloading.

Answer: Maintain a 30' wide clearance from the US Coast Guard small boats at berth and 50' from the WLB. After award, the Contractor is to coordinate with the local operational US Coast Guard units if additional space is temporarily necessary. The Contractor is to coordinate the work schedule with the WLB berth schedule to avoid conflict within these limits.

35. Is there excavation or removals required to construct the Approach Pier Abutment?

Answer: Refer to RFP Appendix A, drawing sheets D1, C2, C3, C6, & WS-6. Riprap may need to be temporarily stockpiled, then restored to install abutment piling. Riprap may need to be removed and excavated to place abutment, wingwalls, and approach apron.

Grading is required for sitework. Per Section 01800 1.5.3, provide excavation for foundations. See revised Appendix A, sheet C6 in this amendment.

44. RFP states "The DOR shall replicate this fender system on the new wharf with the exception that the timber fender piles will be replaced with 13" diameter composite plastic or fiberglass piles." Please confirm that the 13" diameter composite or fiberglass piles shall be used for bidding purposes, but if found during the design analysis to not provide adequate mooring/berthing resistance, this would be a changed condition subject to modification.

Answer: See revised Section 01800 1.8.18. The 13” diameter pile size in the drawings of Appendix A is approximate. The design of the wharf fender system is the responsibility of the DOR. Per the RFP Section 01800 1.8.18, the fender pile solution must consist of fiberglass piles filled with concrete or reinforced plastic piling. The DOR shall select the pile properties to meet the WLB berthing load requirements. The actual solution that the Contractor uses for pile size is not a changed condition.

45.1 Amendment 0004 RFI# 45 for the Sitka Waterfront project asked if the entire standpipe system should be 316 stainless steel. The RFI response stated to follow the requirements of Section 01800 1.10.2.2 which is as follows:

A316 stainless steel schedule 40 vertical fire department connection pipe will be installed adjacent to the entrance of the new main approach pier and shall be routed to the new hose connection manifolds located around the pier. The fire department connection piping will contain a low point drain to allow the water that collects in the vertical standpipe to drain and prevent freezing within the pipe. The fire department connection shall be two 2 ½” outlet connections, cap, and chain, or of a type required by the Sitka Fire department. The fire department connection shall be placed out of the collapse zone of any adjacent building, but no further than 100’-0” from the nearest ire hydrant. The piping serving the fire department connection will contain a swing check valve to prevent the flow of water in the wrong direction. Each new hose connection manifold will be (2) 2 ½” bronze hose valves, unless otherwise specified by the Sitka Fire Department.

In reading this spec section we are interpreting that 316 stainless steel is required for the vertical fire department and the horizontal piping runs around the pier. This is an extremely expensive option and not a typical requirement.

We are accustomed to seeing the vertical fire department connections be 316 stainless steel but the horizontal dry standpipe run being schedule 40 galvanized steel.

Can you please clarify the response to RFI #45 to address if it is required for the entire dry standpipe run to be 316 stainless steel or if just the vertical fire department connections are required to be 316 stainless steel.

Answer: This response amends the response to PPI #45 in Amendment 004.

As defined in Section 01800 1.10.2.2, 316 stainless steel schedule 40 is required for the entire dry standpipe system, which includes the horizontal piping runs around the pier.

46. Sheet C1 shows WLB dolphin as base bid. Sheet WS-5 shows new dolphin as bid option 3.

55. The RFP does not specify that an Incidental Take Regulation (ITR) has been acquired from U.S. Fish and Wildlife Service; however, based on conversations with the agency, it is expected that a proposed regulation for this project will be published in the Federal Register in the near future. Would this ITR become a contract document? Can the Government provide the application?

Answer: Once available, the Government will provide a copy of the published Incidental Take Regulations (ITRs); its publication is expected by July 15, 2025. The Contractor shall abide by all ITR regulations. The Contractor will assume all Best Management Practices (BMPs) found in the Environmental Assessment, and assume practices related to Marine Mammals Protection (MMP) and Endangered Species Acts (ESA) will be applicable/required for the project. Additional BMPs not listed in Environmental Assessment, but required by the published ITR will be considered changed site conditions.

62. Section 01800-1.1.1 states the fencing shall be "hardened". Section 1.4.12 states fencing shall be IAW COMDTINST M5530.1C which does not speak to "hardened" fencing. Please confirm requirement of "hardened" fence and if required please provide requirement for "hardening".

Answer: COMDTINST M5530.1C defines "Hardened" as a security fence that is specifically designed to resist unauthorized access, tampering, and physical attack. See revised Section 01800 1.1.1, 1.4.1, and 1.4.12.

63. RFP Drawings E-1 shows the removal of electrical service to the existing wharf. RFP Section 01800 1.4.1 states, "The scope of work includes the demolition and capping of unneeded utilities". Please clarify whether all existing utilities must be removed from the existing wharf, or just the electrical? If not, please confirm remaining water and sewer lines do not require electricity.

Answer: The new electrical service will feed to the existing approach and will connect to the existing electrical distribution system near the near the existing site transformer that is to be demolished after completion of the new wharf. Reference RFP Appendix A, sheet E6 for required electrical connections. Existing utilities on the existing wharf are to remain.

See Appendix A, sheet D1 for utility demolition, and sheet E1 for electrical demolition.

70. Minimum standoff of the fender system is desired, and the contractor shall replicate the existing fender system but use concrete filled fiberglass piles. It does not appear that there will be room for an energy absorbing fender at the top of the fender pile. If required by the fender designer, can the standoff of the fender piles be increased to allow for the addition of a fender element between the top of the pile and the wharf?

Answer: See revised Section 01800 1.8.18.

75. Paragraph 1.1.1.2 indicates the Boat Bay building is Level 1 and to follow the countermeasures in accordance with the 2021 version of the Risk Management Process ISC standard Appendix B. Please provide Appendix B to the ISC document.
