The equitable adjustment shall be based upon any increase or decrease in costs due solely to the variation above 115 percent or below 85 percent of the estimated quantity. If the quantity variation is such as to cause an increase in the time necessary for completion, the Contractor may request, in writing, an extension of time, to be received by the Contracting Officer within 10 days from the beginning of the delay, or within such further period as may be granted by the Contracting Officer before the date of final settlement of the contract.

• Geotextile will be placed under all riprap as shown in the detailed typical cross sections on pages 3, 5, and 7.

c. Are the Geotextile and Concrete Grout quantities accurate for this site?

All quantities are estimated based on site conditions at the time of evaluation. Actual quantities may vary.

12. Campbell Loop Road Site (Sheet 8): It is called out to install a peak stone dike to correct the 5 wash outs depicted on the plan sheet.

a. The detail provided shows the stone Dike to be at a height of 6’, topped surface at 3’; but does not provide an overall with. Please provide more detail.

The average height of the dike is 6'. Since the existing ground varies, the overall width will vary depending on the ground elevation at any given point. This is covered in the notes on Sheet 8 "Alignment, limits and placement of peak stone dike shall be directed in the field by the COR."

b. This location is heavily covered with large trees within the work zone that are to be cleared. Will the Stone Dike begin at the top of the bank top, or the toe of the water?

We currently do not have permission to bury debris on the properties.

13. “In the specs, page 61-4 #8, it states that the rock riprap shall be delivered to the site and stored in a rock box. Can you clarify this for me? Stephens Construction would like to dump and then place the material as it's dumped. Would that be a problem?”

61-4 #8 States “Rock riprap shall be delivered to the site at the rate it is placed or shall be stored in a rock box.”

14. What if I have a rock supplier that is not on the listed provided Being on the list has nothing to do with a supplier’s eligibility. Any supplier who provides certification that their rock meets our quality/gradation standards is acceptable.
