Article 1 — Description
Furnish and place topsoil to the depths and on the areas shown on the plans.
Article 2 — Materials
Use easily cultivated, fertile topsoil that is free of objectionable material and resists erosion. Obtain topsoil from the right of way at sites of proposed excavation or embankment when specified on the plans, or as directed. Secure additional topsoil, if necessary, from approved sources outside the right of way in accordance with Article 7. 7., “Preservation of Cultural and Natural Resources and the Environment.” Ensure that the topsoil obtained from sites outside the right of way has a pH of 5.5– 8.5, per Tex -128-E . Topsoil is subject to testing by the Engineer. Furnish water in accordance with Article 168.2., “Materials.”
Article 3 — Construction
Remove and dispose of objectionable material from the topsoil source before beginning the work. Stockpile topsoil, when necessary, in a windrow at designated locations along the right of way line or as directed. Keep source and stockpile areas drained during topsoil removal and leave them in a neat condition when removal is complete. Scarify the area to a depth of 4 in. before placing topsoil. Spread the topsoil to a uniform loose cover at the thickness specified. Place and shape the topsoil as directed. Water and roll the topsoil using a light roller or other suitable equipment.

This Item will be measured by the 100- ft. station along the baseline of each roadbed, by the square yard, or by the cubic yard in vehicles at the point of delivery.
Article 5 — Payment
The work performed and materials furnished in accordance with this Item and measured as provided under “Measurement” will be paid for at the unit price bid for “Furnishing and Placing Topsoil” of the depth specified on the plans (except for measurement by the cubic yard). This price is full compensation for securing necessary sources and royalties; furnishing topsoil; excavation, loading, hauling, stockpiling, and placing; watering; rolling; and equipment, labor, materials, tools, and incidentals. Limits of excavation and embankment for payment are shown in Figure 1. Figure 1 Roadway Cross- Sections Showing Payment for Excavation and Embankment
