Procurement Agent: AVCON, INC.

THE FOLLOWING ITEMS ARE MADE AND HEREBY BECOME A PART OF THIS SOLICITATION AS PREPARED

BY PROCUREMENT:

Questions

1. Please provide total embankment & excavation totals in lieu of just excavation.

a. The chart below represents a comparison of the bottom of subgrade elevation for the pavement section combined with the top of finished turf grade outside the limits of pavement compared to surveyed existing grade. Plan quantity for unclassified excavation is listed at 10,250 CY to account for small portion of the existing suitable fill stockpile that was not captured in the survey limits.

The excess cut listed below shall be spoiled on site, north of the existing dry retention area. The slope to tie into grade from the northern top of bank of the dry retention area will be flattened and extended as needed based on actual excess material generated in the field to allow for material to spreading and placement of material on site and to eliminate exporting excess material off site.
