28. What is the thickness of the asphalt to be removed? IN MOST AREAS ASPHALT IS 3” THICK; ASSUME REMOVAL OF 1680SY OF ASPHALT Pending Questions that will be addressed asap via another amendment:

1. In reviewing the Schedule of Values in the proposal documents, we have noticed that there isn’t a line item for Inundated Concrete Walk & Platform. There is a detail on page C20, but no line item on the SOV. It is a different cross section than the typical for concrete sidewalk in that there is filter fabric, so we are not sure if it is included in the schedule of values under another line item.

2. The specification states that HMA shall be placed in two (2) lifts (Spec Section 32.12.16.3). We are requesting an alternative to install the asphalt in one (1) 3-inch lift for both the patching and roadway separately.

3. Requesting clarification on which type of asphalt is being specified. Is it Type I or Type II as there is no reference in the specifications and we need this information to determine the testing requirements.

4. Item 1.20.20.5, Reinforced concrete Slab- 690 SF. Spec says it is for the bike racks, but I can only find 150SF+75SF called out in plans. Please advise on the additional area in the takeoff.

5. Item 1.20.60.3 Seating Boulders, the quantity is 1 EA. What does that quantity refer to? Should it be 1 LS for the boulder wall? Then on L4, it calls out 24”-48” angular boulders surrounding stone marker, by others. But on the same page, it also says 24”-48” boulders in a different location on the plans and gives a detail. Could we please have the boulder item in a LF for simplicity in bidding?

6. Is there any line item/specification for road base material? Also, C22, Typical 1 calls out specifications 31-05-16 and 32-13-13m but they are not included in the Compiled Specifications that I received.

7. On Sheet L8, the 24”-36” Boulder callout refers to Sheet L14, Detail 3. There is no Detail 3 on L14.

8. Flow Velocity in FPS, not CFS. Can you please provide?
