The core scope of work for this tender involves the "Trockenbauabhangdecke Neubau" (Drywall Suspended Ceiling New Construction) project, focusing on the installation and finishing of various ceiling systems across different areas of a new building.

Key deliverables and work activities include:

• Installation of diverse suspended ceiling systems: This encompasses Akustik-Plattendecken (acoustic panel ceilings) of various configurations (e.g., 4 SK, Quadratlochung 8/18Q), Akustikdeckensysteme (acoustic ceiling systems) with different insulations (e.g., 20mm Glaswolle + Tieffrequenzabsorber), and specialized ceiling types like Lochgips (perforated plasterboard) and Baffeln (baffles) in areas such as ancillary rooms on the ground floor, the canopy on the ground floor, and classrooms on the first and second floors.
• Creation of various cut-outs: Manufacturing of round cut-outs with specific diameters (e.g., 68 mm, 120 mm, 205 mm, 280 mm, 305 mm, 405 mm) for elements such as security systems (SiBe), movement detectors, lighting, and ELA systems. Also included is the creation of rectangular cut-outs for pictograms.
• Ceiling finishes and details: This involves the formation of level constructions, ceiling cornices ("Deckenfrieses") of various dimensions (e.g., up to 15cm, 15 to 30 cm, 30 to 50 cm, 50 to 75 cm), and shadow gaps in the edge areas. Other details include wall connections using U-profiles, miter cuts, edge chamfering, and edge sealing.
• Installation of access panels: Integration of revision flaps (e.g., 400 x 400 mm up to 12.5 mm thickness).
• Finishing and quality: All installed components, including panel joints and screw heads, are to be cleanly and professionally plastered using gypsum or joint filler to achieve a surface quality of Q3. The entire construction, including ceiling cornices, must be aligned according to the room axis.
• Labor and documentation: The scope also covers hourly labor for skilled workers and helpers. A crucial deliverable is the compilation of documentation for the performed services, which includes technical declarations from specialist contractors, proofs of usability, approvals/test certificates, product data sheets for installed products, and conformity declarations. This documentation is required in triplicate in paper form (sorted with a table of contents in folders) and once in digital form.
