3 Addendum 1

Prebid Questions and Answers:

1. Does the City know the existing asphalt thickness on Redmond St?
a. The City has no records of existing asphalt thickness on Redmond St.

2. Is the proposed pavement thickness of 3.5” on Redmond Street going to be sufficient
to handle the truck traffic?

a. 3.5” of pavement is considered acceptable. The road does receive truck traffic
however the volume of traffic is not substantial with the street being a dead
end. The majority of the worst distress is located at the end of the street
(intersection with Riverside St and Redmond St). Further, reclaiming will
provide additional strength to the subbase, and it is anticipated that the street
will receive an additional 1”-2” of pavement in the near future in the form of a
shim and overlay, under a different contract.

3. The roller requirements in Item 304.112 and 403.11 may be excessive for the limited
amount of work. Will those rollers be required?
a. All work can be completed with an 8 ton vibratory or oscillatory roller.

4. Is crack sealing over banding 3” per side?
a. No. Maximum over banding is 3” total or 1.5” per side.

5. Are variable message signs going to be required on all streets?
a. No, just the higher traffic (major) roads.

6. Is the lane closure or road detour permit issued by the City and is there a cost for
them?
a. All permits are issued by the City and there is no cost.

7. What is the unit of payment for Item 619.1?
a. The unit of payment is lump sum.

8. Is the quantity for Item 619.1 $8100.00?
a. This was an oversight. There should be no quantity provided for that item.
The quantity should be provided by the contractor on the schedule of values
form. The schedule of values form will be updated and reissued.

IFB0660-040617 4 Addendum 1
