It was built according to the plans of Arch. E.Sagebiel in connection with the construction of the adjacent Tempelhof Airport for the Reich Air Ministry in the years 1937 to 1944. The complex is now a listed building and, together with the airport building and the airlift square, is a listed building ensemble. The overall building consists of eleven interconnected parts. All components have 4 above-ground floors, a non developed gable roof and up to 2 basement floors. In the basement a three-part technical corridor connects all building parts. The media technology supply of the individual building sections is carried out vertically in individual strands from this three-part technical corridor. There is a considerable maintenance backlog in the entire building. The building and the outside facilities as well as the building services (except for the CHP), which are largely disconnected, are to be comprehensively renovated in stages as part of a general overhaul while the building is still in operation, while at the same time making it completely barrier-free. For the project management services to be awarded, services are to be provided in all project stages and all areas of activity.
The project management services put out to tender here, service profile project control for the basic rehabilitation of the Behördenzentrum Platz der Luftbrücke 1-3, D-12101 Berlin, comprise the service areas A, B, C and D in the project stages project preparation, planning, preparation for execution, execution and project completion in accordance with AHO Book 9 (as of May 2014), Part 2 § 2.

Contribution to the feasibility study for the accommodation of company vehicles in a new underground car park to be built in the inner courtyard 2III. Measures Object planning structural engineering and structural design:1. As a result of labour protection law requirements, the staircases and access halls of building components 1-5 and 7 are to be designed and implemented with railing elevations (coordination with the monument protection authority required).2 In terms of monument protection law, the above-mentioned components, together with the façade and the building cubature and the windows, are the main features of monument protection. In the area of the war-damaged building components 8 to 10 as well as the most recently completed building components 6 and 11, the above-mentioned finishing standards are significantly lower, here there are concrete block floorings on the stair steps and landings, simpler railings, partly in the typical training style of the 50s and 60s as well as linoleum-covered corridors. An optimisation of the present design planning for the upgrading of these areas is to be achieved as a special achievement.3. canteen: In the area of component 5, the central supply area with kitchen, canteen hall, small dining room and adjacent cabinets is located. The former kitchen is located on the 3rd floor and will be rebuilt and equipped according to the current requirements. For the area of former kitchen preparation rooms that are no longer necessary, alternative uses are to be developed in coordination with the Monument Authority in accordance with the space requirements of the BImA (meeting rooms, offices, multifunctional rooms).4 Some of the building components still contain original composite wooden windows, which are to be renovated. The present draft planning is to be revised and updated for the necessary renewal of the existing windows (in accordance with the historical stock) in building components 4 and 7, in coordination with the Monuments and Sites Agency.5. examination, supplementation and updating of the existing incomplete EW construction documents (resulting from the approved decision paper for construction according to RBBau) including the cost calculation prepared.6. implementation of structural value preservation measures in almost all building trades (basic repair). Examination, supplementation and updating of the available incomplete EW construction documents (based on the approved decision paper for construction in accordance with RBBau) including the prepared cost calculation7.
