3. Project Structure

a. ODOT State funded project

b. State Buy America Build America (BABA) iron and steel requirements apply

c. Contract administered by Cody Stone

d. Work inspected by AKS

e. MMPA observation done by AKS

4. NOAs

a. Contractor to contact the Coast Guard a minimum 30 days in advance of work in the channel so they can issue a notification to local mariners

b. On page 10 of 00014917_Exh 7-1_Permit Authorization, Item 21 states that the method of pile placement shall be vibratory. On page 11, Item 24 outlines BMPs required during impact driving. The area of piledriving used to have timber dolphins and it is possible that remnants of the timber piles may be encountered in the substrate. Also, the pile records from past dolphin work indicate dense soils were encountered prior to the specified tip elevation. If either of these conditions are encountered, will impact driving be allowed utilizing the BMPs listed in Item 24?

i. The IHA permit only allows vibratory driving. References to impact driving in the permits are left over from the standard template that should have been removed.

c. Is IHA permit on OreBuys?

i. Added via Addendum 1

d. How many piles are lying on the bay floor?

i. The dive inspection report counted nearly 20 piles, but we believe it’s safe to assume all ~30 piles from the previous replacement project are down there.

e. Will ODOT consider adding a bid item for contractor standby exceeding 1 hour for MMPA shutdowns due to marine mammal presence or weather conditions preventing observation? Bidding contractors cannot effectively estimate the number or duration of marine mammals entering the exclusion zone. Nor can the weather conditions that would prevent observation of marine mammals be predicted by bidders.

i. Instead of writing a specification and amending the bid schedule, the contractor, inspector, and project manager will track down time during the work due to MMPA shutdowns and address compensation based on actual standby time incurred via a change order at the end of the project. In order to incur time, shutdowns must me at least 1 hour in length.

f. The plans specify no work zones where eel grass beds are present, which includes no barge use in that location.
