January 5, 2023

Questions Answers 1 Please clarify and/or specify the location of the Vertical Flute as called out on the Wall Relief Detail and Section A-A for the Soil Nail Typical Wall Sections.

Vertical flute spacing is located on the Wall Plan and Elevation sheets for each wall (refer to the corresponding G sheets in the Plan set). For example:

2 Plan Sheet T26, Fixture (Trail Box Steps) shows the use of Alkaline Copper Quaternary (ACQ). Suppliers are telling us ACQ was discontinued as a preservative treatment and a similar water-borne treatment Copper Azole (CaC) is available and meets the same AWPA specs. Will CaC be acceptable?

An answer for this question will be posted with the next QnA update.

11 Can you please provide the chain link fence height for bid item #A1440? The details state that the fabric height is 36” to 96” but I’ll need something a bit more specific than that in order to properly bid the fence (and gate).

Fencing is a standard 6’ height however the height varies with the fence sections being level.

I have a scree clip of the profile below.

Because of this, we respectfully request an extension of two weeks to enable us and all bidders to put together their best competitive bids for you
