1. It appears we will have to maintain the area above the intake free of ice during the execution of the project. Do you have any historical data to give us an idea of the average date when ice comes in on the lake and when it goes out?

Historically the ice forms from 12/15 to 1/15, and melts from 3/15 to 4/15. These dates are estimates and vary based on weather.

2. Are there any calculations on how long it will take to drain the tunnel with only the two 2” air hoses to vent the tunnel?

No.

3. Are there any drawings available for the existing trashracks, or even weights of the racks?

Reference Drawing 519-D-21. This drawing will be added to the specification.

4. Specification 35 23 10, Paragraph 3.03B References drawings 519-D-209. This drawing was not in the set issued. Could we get a copy?

This drawing will be provided in the specification.

5. No Quantity is indicated for the amount of weld filler needed for the repair in Specification 35 23 10, Paragraph 3.03B. Would it be possible to quantify this, maybe even make it a bid item?

The dimension of the weld can be found in detail 3 of drawing 519-D-209. With this dimension the amount of weld material can be estimated.

6. Are there weights available for the gate bonnet covers and gate leaves? Are they light enough to be transported in the freight elevator or will we have to use alternate lifting devices?

These weights are not available. The elevator has a weight capacity of 1000 lbs.

7. On Schedule B bid items 5 & 6 do we insert just the pricing in the unit price side or do we extend them to the amount side? If we are to extend, what quantity do we use for bid item 6?

Enter unit prices only as these are optional line items at this time. They will remain optional line items until after contract award and the trashracks are able to be assessed. Once they are assessed the government will determine the need to exercise the option at the already proposed prices.
