THE FOLLOWING CHANGES WERE MADE TO THE BID SCHEDULE:

1. ITEM 165 621-6002 CONCRETE BARRIER, TP S-2 LF 661 CHANGED TO ITEM 165 621-

6200 CONCRETE SIDE BARRIER, TP 2-S, LF 661

FOR THE CONTRACTORS’ INFORMATION:

Q1. I would like to request clarification regarding line-Item No. 130: CONC SIDEWALK, 8 IN TK – 324 SY. Could you please clarify the what station number associated with this particular item?

R1. 8 Inch thickness in curb return radii and wheelchair ramps.

Q2. Per the contract drawings, the concrete barrier wall is designed as Type S-2. However, field conditions and the existing grading indicate that the elevation difference from the face of barrier to adjacent grade exceeds 1 foot, which meets the criteria for a Type S-3.

Please confirm the correct barrier wall type to be used for bidding and construction.

Additionally, advise if any revisions to the plans or details will be issued to reflect this condition.

R2. The pay item on the detail estimate for the wall shows 621-6002 Concrete Barrier, Type S-2, which is a pay item for a S-2 median barrier. The plans show a Type 2-S Side Barrier (using GA Std 4949B), which required pay item 621-6200 Concrete Side Barrier, TP 2-S, LF.

Q3. Will this project utilize the GDOT Asphalt Cement Index for the Paving?

R3. Index will be applied per the current GDOT Specification.
