2016 Culvert Replacement Project General Notes & Road Log

General Notes

Information given for specific culverts is approximate and intended only to give the contractor a general idea of the degree of effort required for excavation. Field visits are recommended. Linear dimensions listed are from the edges of the road along the ground slope to the end of the culvert. Fill estimations are approximately the amount of embankment associated with each site, and are not the estimated excavation quantities to replace the pipe.

The Pay Items for culvert installations are divided up into two categories to clarify amount of effort/degree of difficulty in excavation and embankment.

Type 1 excavation: culverts are at a depth 7 feet or less at the outside edge of road, measured straight down into the embankment.

Type 2 excavation: culverts are at a depth between 7 feet and 14 feet at the outside edge of road, measured straight down into the embankment.

Construct a rocked rolling dip at each site. On flat roads, the dip should be placed on top, or nearly on top the new culvert. On sloped roads, the dip should be placed a few feet downslope from the new culvert location.

Place 36 tons of surface aggregate on the road surface over disturbed area of each culvert installation.

Spread government furnished seed evenly on disturbed areas, at approximately 25 pounds per acre, prior to mulching with straw. Use a hand-held spreading machine.

Sites with flowing water need to be dewatered before the old culvert is removed and until the new culvert is installed.

Existing culverts to be replaced are not designated for salvage and shall be disposed of according to 203.05-Disposing of Material, Section a) Remove from project and off government lands.

At least 14 days prior to beginning work, the contractor shall provide an erosion control plan in accordance with Section 157, Erosion Control.

As noted in Specification 602.03-General, the contractor shall measure each culvert and submit the list to the contracting officer prior to ordering pipe.
