What do you mean by crosswalk? Sidewalk? Concrete? Asphalt? Just crosswalk striping?

Crosswalk referenced in parking lot C is just a crosswalk striping.

You are having us remove concrete what is the depth of concrete in these areas?

Depth is unknown at this time. Please field verify.

Are you looking for us to provide line striping for each parking lot? Once we mill and overlay the lots will need to be restriped?

Yes. After the job is complete, all new striping must match what is there now.
On the Google Earth drawing for parking lot A, it says 150 LF of striping. That is not the entire lot, so I am confused at to what you are looking for. The same for parking lot C and Q.Â

For parking lot A, 150LF means that the space spans 150 feet. This 150 feet is not currently stripped. This will be new striping. The spacing in between each new strip shall match existing space between other striping in same lot.
For parking lot C, new striping refers to crosswalk striping.
Parking Lot Q does not mention any new striping from what is existing. This means that all new stripping must be replaced with what is currently existing.

Are you looking for line striping for parking lot Q? It doesn t state it on the drawing.

Yes, as mentioned in the scope of work, In addition, the striping of the roads, including the striping of the cross sections of roads/parking lot striping, in-kind striping to what is existing. This means that the existing striping must remain. Obviously, you will remove them, mill and fill, and then strip new to match existing striping layout.

Do you have details for the concrete pad? What is the depth of concrete? Is there rebar?

Dumpster concrete pad is 10 x12 x10 Thick, compressive strength 5000 psi with #5 at 10 top and bottom. Provide a perimeter haunch to a depth of 18 inches.

Can you provide any clarification on the mill and fill scope. We see they mention mill 3" and replace 3" for the roadway but I don't see what they are looking for in the parking lots? Also depths on the binder and top?

The parking lot will have the same 3 or match existing roadside thickness.

Please provide site visit roster.

See attached.

Can the Site Superintendent serve as Site Superintendent, Quality Assurance Manager, and Safety Manager?

Yes.

Documents says 3" of asphalt, is this 3" compacted? Is it one lift or two lifts?

We will be using two lifts, scarify 1-1/2 binder course with a 1-1/2 top layer.

Also I am seeing that it is SuperPave Asphalt- can you confirm this?

Correct.

Project duration 15 calendar days is not enough time. Need at least 2 weeks cure time before seal coast new asphalt. Also need cure time on concrete before try to roll against it. Please advise.

We can accommodate to what s realistic. Please provide a timeline.
