Common use of Sampling Design Clause in Contracts

Sampling Design. An appropriate and defensible sampling design should be used as the basis for data collection for use in compliance decisions. The choice of a sampling design depends on several factors including but not limited to, the decision to be made with the data, frequency of dredging, historical or known location of shoaling, historical or known volumes of materials dredged, and cost of sampling and analysis. Chapter 8 of both the Green Book and ITM, should be used for detailed guidance for developing the sampling strategy, however, the guidance provided in the ITM is more technically advanced and should be used as reference for preparing a sampling strategy. Plumb (1981) provides additional guidance on sample design.
