The tests to be performed on site, or in parts of the project, are defined in the testing plan. To verify the characteristics and behaviour of the materials to be used, samples must be taken and tests performed as specified in the contract specifications. These specifications typically define the type and frequency of the tests as illustrated in Table 13.4. The codes used are listed at the end of the Table.
