213.1DESCRIPTION
1 This section describes the requirements for removing and replacing overburden material from a material source.
213.2MATERIALS—V acant
213.3EQUIPMENT—V acant
213.4CONSTRUCTION
213.4.1 General
1 Strip topsoil in accordance with Section 207, Topsoil, and stockpile separately from the overburden stockpiles.
2 Strip material sources to the depth and extent necessary for the production of a quality material. Portions of the material source to be used and overburden stockpile locations may be designated by the engineer. Place overburden in neat, uniform stockpiles, located to not interfere with the removal of material from the source.
213.4.2 Replacing Stripped Material
1 After the construction materials are removed, place the overburden over the material source area before placement of topsoil. Place the material uniformly, and smooth it to blend with the surrounding terrain. Place topsoil in accordance with Section 207, Topsoil.
213.5MEASUREMENT and PAYMENT
213.5.1 General
1 The engineer will measure:
measurements.
between the original volume in the stockpiles and the volume remaining in the stockpiles upon completion of the work.
If overburden is stripped from its original position and placed directly in its final position, it will be measured as Overburden Placing. The quantity will be
Overburden SECTION 213
determined from preliminary and final volumetric measurements of the stripped area.
2 The engineer will not make additional measurements if overburden stockpiles are moved to facilitate material source operations, except when the stockpile locations were directed by the engineer.
3 The department will pay as follows:

213.5.2 Referenced Sections for Direct Payment
1 When specified, the engineer will measure and pay for removal and placement of topsoil in accordance with Section 207, Topsoil.
