AK PRA DENA 10(36),

Replace Ghiglione Bridge

# General Technical Question Answer Date

1 X

Bridge drawing 7 of 29 (RG3147-G) requires that the sole plate be vulcanized to the elastomeric bearing pad. Section 555 – Steel Structures of the Special Contract Requirements requires structural steel fabrication to be completed by an IBR certified facility. Does this requirement pertain to the sole plates?

That requirement would not apply to the bearing sole plates.

Bid according to the plans 11/7/25

Is the July 1, 2026 start date based on when the

Polychrome bridge will be completed, and could we start earlier if other lodging arrangements are made and we do not need to access Toklat?

Bid according to the plans 11/7/25

Is it acceptable to install a temporary culvert over the creek for temporary crane/drilling access?

This is not currently permitted 11/7/25

Check General or Technical

Section 637.03 (Page E-29) states to deliver vehicles to park headquarters on Notice to

Proceed Date. Also states vehicles will not be operated during winter shutdowns. NTP date listed elsewhere as 1/05/26. No work is allowed on the project until 7/01/26. Why would vehicles be needed on 1/05/26 if they are just going to be parked at the headquarters until July? Please consider revising delivery dates on vehicles to some limited time before start of work date

Your question will be addressed via an amendment.

Section 107.10(e)(3) (Page E-24) does not allow clearing to take place between May 1 and July

31. Section 108.01(a)(1) states no onsite work before July 01, 2026. Clearing needs to be performed prior to any other work onsite. This essentially pushes start of work date back to

August 01. With an August 01, 2026 start date, our schedule shows we cannot complete work prior to September 30,2027 while following the other work constraints on the job (winter shutdowns, snow removal dates, etc). Will owner allow clearing to take place subject to pre-inspectin for migratory birds? Who will pay the cost of this pre-inspection? Will owner allow clearing to take place prior to the May 01 date? If neither of these is allowable, we would request that the contract completion date be extended to allow for completion of work in spring 2028.

Your question will be addressed via an amendment.

Plan sheet D.2 shows 18’ wide access road on east side of creek to access Piers 1 and 2. Will similar access road be allowed on west side of creek to access Pier 3?

Bid According to plans. 11/7/25

Plan sheet D.2 shows Construction Limits relative to access to Piers 1/2/3. Using original ground contours, an access road to Pier 2 and

Pier 3 that stays within the Construction Limits would be too steep for any equipment to use

(well over 30% gradient). Can Construction

Limits be extended to the Wilderness Boundary for the sole purpose of providing adequate access to Piers 2 and 3?

Bid according to plans. 11/7/25

With the potential for very limited access underneath the bridge for stripping operations, as well as the potential cost and time savings, will stay in place deck forms be allowed on this project?

Section 108.01(c) (page E-29) Overweight vehicle restriction references that between May

01 and Sept 21, overweight vehicle traffic is not allowed between the hours of 6am and 10pm.

This section does not define what constitutes an overweight vehicle. Please clarify.

See SCR section 104.05 11/7/25

14 X

Bid schedule contains 850 Flagger Hours. I’m not finding any reference in the ITB that clarifies when we are allowed (either dates or times) to restrict traffic under flagger control. Please clarify.

Bid according to the plans, See SCR section’s 156 and 108.

Addendum #1 changes this date to 30 days prior to preconstruction conference. However, with

NTP date of January 05 and start of work no earlier than July 01, it is likely the preconstruction conference happens far earlier than 30 days prior to July 01. Please review, consider changing vehicle requirements to “X” days in advance of start of onsite work

Your question will be addressed via an amendment.

I wanted to get clarification on the size of the wedge plates on drawing RG3147-L (bridge drawing 12 of 29). They are shown as tapering from 3.5” to 2.5” and are 15” long. There is a callout for “2” plate”. Is that the width?

Yes this is the width. 11/7/25

Could you give us the haul route that you anticipate for getting the scrape material from the mining area on the far side of the river over to the stockpile areas? If a river crossing is required, what are the environmental stipulations that are applicable?

See SCR 105.02(a)(1)(a), contractor to

Submit planned Haul Route, If a river crossing is required, adhere to applicable permits.

Usually the “B pages” will include FAR 52.204-8, subsection (b), which gives us the option to check “Paragraph (d) applies”, but this FAR clause is missing from the B pages for this project entirely, therefore unable to check it.

The FAR Overhaul removed provision

52.204-8, Annual Representations and

Certifications.

Per FAR Clause 52.204-19, Incorporation by

Reference of Representations and

Certifications, “The Contractor’s representations and certifications, including those completed electronically via the

System for Award Management (SAM), are incorporated by reference into the contract.”
