About this tender
The Gemeinde Buggingen is procuring the refrigeration installation (Kältetechnische Anlagen) for the new extension of the Grundschule Buggingen, Wilhelm-Ritter-Straße 3, 79426 Buggingen. The extension is a two-storey, non-basement L-shaped building of about 9,400 m³ gross volume. Refrigeration is being added after the building contract was awarded, but while construction is still underway. The procurement is classified under CPV 45331220-4 as a works contract (Bauleistung) under an open procedure under Directive 2014/24/EU and the German EU VOB/A. The scope includes supply and installation of an air-cooled chiller (refrigerant R 290, about 56 kW cooling capacity) with hydraulic module on the flat roof, including crane lifting. It also covers a heat exchanger (55 kW), a 2,000-litre cold storage tank, pumps, valves and meters, and steel piping (DN 15–65) with refrigeration insulation (Armaflex inside, sheet-metal cladding outside). Connections are required to the cooling coils of the ventilation units and to the underfloor heating used for surface cooling. The works also include integration into the building management system (GLT) via Modbus, coordination with the GLT and heating trades, commissioning, balancing, as-built documentation, and registration with the grid operator. A four-year full maintenance contract is included in the scope and counts toward the evaluation. Work must be carried out during ongoing school operations, so noise-intensive tasks and deliveries must be coordinated with the school. A site visit is recommended. The estimated execution period runs from 11.01.2027 to 30.04.2027. The procedure has already closed for document requests and the submission deadline was 23.11.2026 at 09:40.
