The quantities stated in the list of services are not guaranteed quantities. The contractor has no claim

For a minimum turnover

The quantities stated in the list of services are not guaranteed quantities, ie the contractor is not entitled to a minimum turnover. The positions to be eaten in the list of services (EP, GP) serve to determine the most economical offer. In the case of an order for the framework contract, the unit prices (EP) will be commissioned. The following quantities serve as a guide for the contract period of 4 years.

The drinking water tests for the chemical parameters lead, copper, nickel and the microbiological test for the parameters Escherichia Coli (E.coli), enterococci, number of colonies at 22 O C and 36 O C, coliform germs, Pseudomonas aeruginosa, and the measurement of pH and conductivity are carried out on suspicion or if necessary and before the first commissioning of drinking water installations. The services to be provided include:

general services:

The contractor must permanently mark each sampling point during the first sampling on site as a sampling point according to the Drinking Water Ordinance by attaching appropriate signs. The contractor will check the sampling point specifications, if any, provided by the client for their suitability for the commissioned tests in accordance with DVGW W 551 or in accordance with the latest recommendations of the Federal Environment Agency and, if necessary, determine suitable sampling points.
