The following are questions, answers, and clarifications to the IFB #495-26 Roadway Rehabilitations and Culvert Replacements:

1. QUESTION: On page 9 the description for Afton Rd and Emma Terrace calls for mill and overlay, which one would assume that the whole road would be milled. Afton Rd has a pay item for Mill Butt Joins and Emma Terrace does not have a pay item for any milling. Please clarify the milling operation on these two roads.

ANSWER: Milling included in the tonnage.

2. QUESTION: How will dirt or gravel side roads and driveways be handled in this project? Will the contractor run the spreader gate out or should we use the GDOT misc. Unpaved Spec for paving roads and driveways? Please clarify.

3. QUESTION: On Cowart Rd there is (5) existing brick mailboxes @ 859, 1681, 1772, 2031, & 2307. Generally the brick mailboxes are moved or replaces by the homeowner not the contractor.

Please advise.

ANSWER: Included in the tonnage.
