With this tender, the UKH intends to conclude a framework contract for a maximum of 4 years (36 months and one-time extension option) for the transport of water samples as well as the systemic microbiological examinations and findings from all water systems of the UKH that are subject to inspection according to the Drinking Water Ordinance. Samples are taken by qualified employees (certified employees with a sampling certificate) from the UKH. The samples are picked up by the contractor at the UKH locations, brought to an accredited test laboratory that uses accredited test methods, and examined and assessed there in accordance with the accredited methods (see Appendix 1 "Water samples and parameters to be examined"). Suitable sample transport boxes are free of charge and sample transport bottles that are presented with thiosulphate will be provided by the contractor for a fee.
The contractor examines the parameters shown in Appendix 1 "Water samples and parameters to be examined" in accordance with the order and survey form enclosed with the water sample and the accompanying note. Sampling at the sampling points is carried out by qualified UKH employees who have a sampling certificate. The contractor offers the employees of the UKH extensive instruction / training / audits for certified sampling as well as integration into the quality management system of the contractor.
The routine tests are the water samples shown in Appendix 1 “Water samples and parameters to be examined”, which for the most part must be sampled every six months and, in a few areas without patient reference, once a year and microbiologically examined. The number of samples and parameters to be examined can change due to changes in the building stock, changes in use, changes in legal regulations, etc.
The water samples are accompanied by an order sheet and a questionnaire, as well as an accompanying sheet, which the testing laboratory must use for orientation.
In addition to the routine examinations, follow-up samples or special samples (accumulations, outbreaks and accidents) of unknown numbers are carried out. These are dependent on the results of the current findings from routine samples, to check the success of measures taken (e.g. disinfection, rinsing, etc.) or, if necessary, to a lesser extent on the basis of special examinations (further examinations, environmental examinations, implementation of a dental unit, examination of a dental unit after these Installation, etc.). The contractor will be informed about these and the selection of the corresponding parameters. This includes a telephone notification in advance.
At the sampling date, the water samples are taken by certified UKH samplers in accordance with the sampling scheme purpose b) and c) of DIN EN ISO 19458, DIN 38402 Part 14 and the specifications of DVGW worksheet W551 and collected by the contractor by 12 p.m. and taken to the test laboratory brought. The sampling dates and the location of the collection of the water samples will be communicated to the contractor by the UKH sampler. In special exceptional cases, on regular working days (Monday - Friday) it may also be necessary to collect the goods between 12 p.m. and 6 p.m. There is no separate calculation. The contractor enables the collection and microbiological analysis of water samples in an emergency outside normal business hours (from 8 a.m. to 6 p.m.) on weekends, public holidays and in the evening and at night. However, this is the exception.
