QUESTION AND ANSWERS:

1. Where can I find the plan holders list on your web site?

The Planholders list is available upon email request to wallaces@akrr.com.

2. For bonding/surety reasons, what is the Engineer’s Estimate or budget for the project?

The Alaska Railroad Corporation has developed an internal cost estimate for this procurement;

however, it will not be disclosed. Offerors are responsible for proposing pricing based on their technical approach, level of effort, and understanding of the requirements. Pricing will be evaluated for overall reasonableness and alignment with the proposed solution.

3. Corps Permit Page 3 of 9, full length silt curtain used on the south end of the dock expansion between the sheet pile construction and the west side of the sediment groin. If this is a requirement, please explain in further detail. Where, when, to install, when to remove.

To be addressed in Addendum 2, currently pending PM review.

4. Could the engineer provide an estimated pulling strength required to remove the spin fin piles? Is the thought that these can be pulled without damage?

5. Are any of the existing dolphin piles filled with concrete or gravel?

6. Several times the Corps permit refers to “in-water work year”. Please define.

7. 2.1.2 Mitigation Measures 3. Says in-water work will be conducted at the lowest points of the tidal cycle when feasible. Is it reasonable to think piles could be driven and pulled at any tide, some fill operations would be better off at lower tides, filling above the tide levels for the most part?

8. Who is responsible for sunflower sea star surveys and relocating them?

9. Sheet 5 of 37 shows survey control. Assuming points 601, 602, and 603 are most likely destroyed by the cruise ship dock demolition, are there any replacement control points available?

10. Could you provide quantities for the Install South Slope Armor Rock, the Install East Slope Riprap, and various layers of fill for the Sheet Pile Dock Extension?

11. Could you provide Sheet 11 of 37 with existing topography, bathymetry shown through the extension area?

12. Will you be providing Open Cell Dock construction specifications or do we use the railroad standard specs for piling?

13. Will Builder’s Risk be required on this project?

14. Will Railroad Protective insurance be required?

To be addressed in Addendum 2, currently pending review.

15. For the Bid Items No. 2 and 3, Salvaging armor rock, will this be paid by cross section of existing or cross section of the resultant stockpile, or another method?

16. If additional riprap or armor is required, is the existing stockpile at the dock storage area available for use on this project at no cost to the contractor?

17. For alternate Item A2 do you have existing depths along the face?

18. Note on Sheet 23 of 37 says PS27.5 may be substituted with PS31’s. What sheets are allowed to be PS27.5?

To be addressed in Addendum 2, currently pending PM review.

19. Regarding owner furnished sheet piling, are they all PS31 or are there some PS27.5?

20. The permit does not allow impact pile driving July 15 to September 15. Am I missing something or will in-water work be allowed year round except for impact pile driving?

21. If longer sheet pile is cut for 60’ foot sheets, does the railroad want the cutoffs or will the contractor be required to deal with them?

22. What is the pin pile specification, diameter, wall thickness, etc for the fender assemblies?

23. In the past there have been some projects where the question of compatibility between 2 different sheet pile manufactures was an issue. Is that going to be a concern where the expansion ties into the existing X Pile on this project?

24. What is the pin pile specification, diameter, wall thickness, etc for the fender assemblies?

25. In the past there have been some projects where the question of compatibility between 2 different sheet pile manufactures was an issue. Is that going to be a concern where the expansion ties into the existing X Pile on this project?

To be addressed in Addendum 2, currently pending PM review.

26. I believe Harris Sand and Gravel replaced a batter pile on the dolphin in 2020. Was the damaged pile pulled in it’s entirety, or was it cut off and replaced with a new spin fin pile?
