About this tender
The Emschergenossenschaft is procuring engineering consulting and revision support (Ing.-Beratung und Revisionsbegleitung) for the WSÖ (Wirbelschichtöfen, fluidised-bed furnaces) and RRA (Rauchgasreinigungsanlage, flue gas cleaning plant) at the ZSB Bottrop sludge incineration facility. The plant thermally treats about 120,000 tonnes of sludge fuel per year in two combustion lines, each with a maximum thermal capacity of 9.9 MWth, plus associated energy generation and flue gas cleaning. The contract covers demand-driven engineering support for operation of the plant (referenced as 21-ME-50), given its technical complexity and ongoing requirements for availability, emissions compliance and process optimisation. The service is expected to be needed on an as-required basis rather than as a fixed-volume scope. The contract period runs from 01.08.2027 to 31.07.2031, i.e. four years. The place of execution is 46238 Bottrop. The procedure is a negotiated procedure with a prior participation competition (Verhandlungsverfahren mit Teilnahmewettbewerb). The tender is not subdivided into lots, and side offers are not permitted. Several main offers are permitted. Relevant CPV codes are 50410000-2 (repair and maintenance services of measuring, testing and checking apparatus) and 50531100-7 (repair and maintenance services of boilers).
