Summary
Machine-generated summaryThe City of Hannover intends to build a six-stream integrated comprehensive school (IGS) in the Kleefeld district, including a three-field sports hall, outdoor sports facilities and external works. The contract covers planning, construction and financing services as well as maintenance work during the extended warranty period. The new buildings are to be constructed to near passive house energy standards, based on a functional performance specification. The building plots, around 27,900 square metres behind two existing schools, currently serve as outdoor school grounds. A main water main runs across the site and may not be built over. Space programmes provide about 7,389 square metres for the school building and about 1,684 square metres for the sports hall. Realisation follows the owner model, with ownership remaining with the public contracting authority, and completion is targeted for the end of 2030.
