906.3 Construction Requirements
Before excavating topsoil from the Contractor-furnished site, remove all grass, weeds, brush, stumps and other objectionable material from the site. Spread the topsoil at the locations and to the depths shown in the Contract Documents. Do not harm existing plants or structures when placing and spreading the topsoil. Do not spill the topsoil on the roadway. Do not handle or spread topsoil when it is wet enough to form a 1 ½ inch soil ball without easily breaking. Use only pulverized topsoil where 3 in ches or less of topsoil is required. After the topsoil is spread over the designated areas, remove any stones, roots, large clods (greater than 6 inches) and other objectionable material.
906.4 Measurement and Payment
a. Contract Quantities. The Engineer will use the contract quantities for payment, provided the project is constructed essentially to the lines and grades shown in the Contract Documents. If the Contract Documents are altered, or if the E ngineer or Contractor ques tions the accuracy of the contract quantities for topsoil, either party may request measurement of the quantities involved, when excavated, or after placed. b. Measured Quantities. The Engineer will measure (by cross-sectioning) topsoil by the cubic yard. The Engineer will compute the quan tities by the average end area method. Wher e it is impractical to measure material by the cross-section method, the Engineer may use three-dimensional measurements. c. Payment. Payment for "Topsoil" at the contract unit price is full compensation for the specified work.
