About this file
Addendum No. 4 is a clarification document issued by the Alaska Railroad Corporation (ARRC) on April 10, 2026, in response to bidder questions regarding Invitation to Bid (ITB) 26-13-214320 for the Seward Freight Dock Expansion Fender System. The solicitation, originally posted March 9, 2026, with an initial closing date of April 7, 2026 (extended to April 21, 2026 per Addendum 2), requires the fabrication and delivery of six marine fender systems to the Port of Seward. Bidders must comply with detailed technical specifications and submit shop plans, material certifications, and fabricator certifications. The contract term extends from ten calendar days after award through project completion, with performance expected to commence within ten days of the Notice to Proceed and delivery expected before October 15, 2026. Payment is structured in three phases: 10 percent upon approval of submittals, 40 percent upon approval of fabrication and quality reports, and 50 percent upon acceptance of delivered fenders.
Addendum No. 4 addresses four critical bidder questions regarding material substitutions and delivery logistics. ARRC clarified that spray metalizing may be substituted for hot-dip galvanizing (HDG) on fabricated fender panels if the contractor can guarantee that ultra-high-molecular-weight (UHMW) panels with tee slots can still be installed; the contractor must identify applicable size limitations if needed. The contractor bears responsibility for offloading fender systems from barges upon delivery to Seward, with ARRC providing storage location. ARRC approved the substitution of 24-inch Schedule 60 (0.969-inch wall) pipe for the specified 24-inch OD x 1-inch wall pipe in clamp bracket fabrication due to domestic mill availability constraints and minimum purchase requirements. ARRC acknowledged that open-cell rubber fenders have no domestic manufacturers and only imports are available, permitting non-domestic sourcing for these specialized materials. All bidders are required to acknowledge receipt of this addendum and all prior addenda in their supply bid forms.

ADDENDUM NO. 4
Invitation to Bid (ITB) 26-13-214320 Seward Freight Dock Expansion – Fender System Alaska Railroad Corporation Date: April 10, 2026
This Addendum is issued to provide clarification and additional information in response to bidder questions. All other terms and conditions of the referenced solicitation remain unchanged.
QUESTION AND ANSWERS:
1. Once the Fender Panel is fabricated, it will be too large to have HDG. In lieu of galvanizing, can we metalize the fender panels?
No exceptions to the substitution of Spray Metalizing. If Spray Metalizing is substituted for galvanizing, the Contractor shall guarantee the UHMW panels, with Tee Slots, can still be installed and slide over the steel Tees.
a. Alternatively, the contractor could provide the size limitations. If the issue is length, say if it needs to be under 40’, we may be able to sharpen the pencil on the pipe sleeve length. If the width is limiting, I don’t think there is much we can do other than have part of the panel galvanized and allow for galvanization repair at the weld locations that tie it together.
Alternatively, the Contractor could identify the applicable size limitations. If the constraint is length (e.g., requiring sections under 40 feet), ARRC may be able to reduce the pipe sleeve length accordingly. If the limitation is related to width, there appears to be limited flexibility; in that case, a potential approach would be to galvanize portions of the panel separately and perform galvanization repair at the field weld locations used to join the sections.
b. Spray Metalizing Specifications were not provided with the fender package. We recommend you provide the Spray Metalizing specifications in the Freight Dock special provisions. The main application spec in section 716-2.09. The Galvanizing Repair section in the fender package could also be applied to spray metalizing repair.
2. Delivery: I see delivery is to the Seaward Terminal, once there will AKRR be providing the offloading from the barge?
Reference Response to Question 3 on Addendum 1. Offloading from the barge will be the responsibility of the Contractor. ARRC will provide location for storage of Fender Systems in Seward upon delivery
3. On the Fender Clamp Brackets the drawings indicate that a piece is to be cut from a 24” OD x 1” wall pipe and welded in however that size of pipe is not readily available. There is only 1 domestic mill that can produce it and they require a 200-ton minimum. Can 24” sch60 (0.969” wall) pipe be used in lieu?
mailto:wallaces@akrr.com
No exceptions to the substitution of the 24” sch 60 (0.969” wall) pipe.
4. What origin is acceptable for the Open Cell Rubber Fenders? There are no domestic manufacturers in America that make/produce these products at all, only import is available on items such as these.
The Alaska Railroad Corporation acknowledges that certain specialized materials may not be manufactured domestically. Refer to Addendum No. 3, Question 1.
Please acknowledge receipt of this and all addenda in your firms Supply Bid Form (Form 395-0129).
