# Heating-plant connection at Ölper: civil engineering and pipeline works

Braunschweiger Versorgungs-AG & Co. KG is tendering civil engineering and pipeline works for a district-heating connection to the Ölper heating plant, across the northern sections of the route. The official TED notice contains two lots: civil engineering (€2.45 million estimated) and pipe construction (€1.85 million estimated), both planned from 1 March 2027 to 30 September 2028. A pipeline-construction certification under AGFW FW 601 is required for Lot 2. Price is the sole award criterion at 100%. The TED notice sets the bid deadline at 3 November 2026, 10:00 UTC+01:00; that explicit source time differs from the immutable timestamp.
