Summary
Machine-generated summaryThe buyer procures planning services for engineering work covering the roof and energy refurbishment of Buildings C and D at the Philipp-Matthaeus-Hahn School in Balingen. The two connected buildings date from 1978/1979, offer over 6,000 m2 of usable floor area, and house mainly workshops and classrooms. They are single-storey without a basement, built in solid construction with reinforced concrete structures, flat roofs and shed roof elements. A two-storey timber storage building with a gently pitched metal roof was added to Building C in 2005. Work must proceed during ongoing school operations, with dirty and noisy activities scheduled during school holidays where possible. Completion and handover are planned by December 2032.
