Details: On the south-eastern part of the campus "im Neuenheimer Feld" in Heidelberg, a multi-storey laboratory and research building in reinforced concrete skeleton construction with two underground and 4 above-ground floors for the Dkfz is to be erected. The building, which is around 24 m high and wide and around 45 m long, is divided into a northern and a southern access section as well as a freely usable laboratory area, which spans between the two sections and a metal-glass façade, on two floors with an F30 requirement , with cladding of the opaque areas as a rear-ventilated wooden facade. The sun protection is planned as an external screen on the two upper floors and as sun protection glass with printing on the ground floor. The other building facades of the access spans are clad with a rear-ventilated facade made of prefabricated reinforced concrete parts. On the north and south sides, a ground-based green facade with climbing aids is planned, each taking up about three quarters of the area. The flat roof is extensively planted and planned to be equipped with PV elements. On the 3rd floor, the inner courtyard has a spacious planting basin with intensive greening. In addition to the development of the building by the users, the infrastructure links also serve the technical media development of all areas of the Hlsk, laboratory media as well as electrical and EDP supply in the 4 shafts on all floors. In addition, the IT and Elt rooms can be found in the brackets on each floor. The sanitary and wet areas can be found on all floors with work and lounge rooms in the northern section. Due to the position of the main entrance in the northern part of the building, the Stb stairs located there and the elevator within the clasp function as a higher-level access. The southern stairwell with an identical Stb staircase serves as a second structural escape route. A qualified GMP area will be created on the ground floor in accordance with the currently valid GMP and radiation protection requirements, which will be supplied via a corresponding plenum located above. Above that, on the 1st floor, is the technical center for ventilation, which also supplies the theranostics area on the 2nd floor and the synthesis and radiochemistry laboratories on the 3rd floor. The exhaust air duct leads over two steel truss bridges to and from the existing cyclotron building to the high-rise building and over the same. Other technical systems for heating, sanitary, compressed air, electrical and building automation are located in the two basements. The heat pump with suction and injection well technology is housed in the heating center. The building will have a semi-stationary extinguishing system in some areas where smoke cannot be extracted for reasons of radiation protection. Apart from the aluminum and glass walls with clean room requirements on the ground floor, the interior design is done as dry construction, some areas are planked, doors are also planned as aluminum glass or painted sheet steel or wooden doors. Suspended ceilings are only available as plasterboard ceilings in some areas of the corridors for fire protection reasons and as open wooden slat ceilings in corridors without requirements and as walkable clean room ceilings between the ground floor and the plenum, the laboratories do not have suspended ceilings and are installed openly. Screeds are designed as bonded screeds or on a separating layer, are mostly provided with rubber floors and the surface of the corridor areas is finished. The sanitary areas are tiled. The outdoor facilities form their main extension in the western part of the property above the substructure with an inverted roof, retention areas, shrub areas, benches, access roads and bicycle parking spaces, where the main entrance is also located. In the east, the building ends with the property line directly on the public sidewalk. North and south of the building are smaller lawns across the full width of the building. Earthworks are taking place to a lesser extent than is usual with a building of this size, since most of this has already taken place as part of the demolition work. Minor demolition work is being done to establish the connection to the existing cart walkway to which the building and its supply and disposal lines connect.

Where Excavation To The Finished Graded Section Results In A Subgrade Or Slopes Of Unsuitable Soil, The Engineer May Require The Contractor To Remove The Unsuitable Material And Backfill To The Finished Graded Section With Approved Material. The Contractor Shall Conduct His Operations In Such A Way That The Engineer Can Take The Necessary Cross-sectional Measurements Before The Backfill Is Placed. The Excavation Of Muck Shall Be Handled In Manner That Will Not Permit The Entrapment Of Muck Within The Backfill. The Material Used For Backfilling Up To The Ground Line Or Water Level, Whichever Is Higher, Shall Be Rock Or Other Suitable Granular Material Selected From The Roadway Excavation, If Available. If Not Available, Suitable Material Shall Be Obtained From Other Approved Sources. Unsuitable Material Removed Shall Be Disposed Of In Designated Areas Shown On The Plans Or Approved By The Engineer. 102.3 Method Of Measurement The Cost Of Excavation Of Material Which Is Incorporated In The Works Or In Other Areas Of Sill Shall Be Deemed To Be Included In The Items Of Work Where The Material Is Used.
