Tenders Are Invited For Electrical Fitting Work – New Construction Of A Triple Sports Hall In Delbrück, Electrical Work

Electrical Fitting Work – New Construction Of A Triple Sports Hall In Delbrück, Electrical Work. The Subject Of This Procedure Is The Awarding Of The Electrical Work. In Detail: Photovoltaic Systems: A Pv System With Approx. 46.5 Kwp Is Planned On The Roof Of The Gymnasium. The Modules Are Aligned Using An East-West Elevation. The String Lines Are Laid On The Roof Using Cable Support Systems. The Inverters Should Be Positioned In The Technical Room (Axis H-I/1-2). Low-Voltage Switchgear / Sub-Distribution: The House Connection Box Is Installed By The Utility Company In The House Connection Room (Axis J/3-4). The Transformer Measuring Cabinet And Low-Voltage Main Distribution Box (Nshv) Should Be Installed In The Same Room. The Nshv Will Supply A Sub-Distribution (Main Building Distribution (Ghv)) And A Photovoltaic Control Cabinet. The Ghv Should Be Installed In The Control Room (Axis F/3-4). Cables And Lines/Laying Systems: The Cables And Lines Must Be Designed As Halogen-Free Lines. The Cables/Wires In The Walls Should Be Laid Under Plaster. Exceptions Are Technical Rooms, Storage Rooms, Outdoor Equipment Rooms, Pumi Rooms And Storage Rooms. Here The Cables Are Routed In An Attractive Surface-Mounted Installation. The Installation Systems Are Expanded Using A Cable Support System And Individual Fasteners. The Construction Of Cable Routes In The Gymnasium Is Carried Out Using Empty Pipes (In Concrete) And In The Area Of ​​The Cavity Of The Gymnasium Floor. Lighting Systems: Dali Dimmable Lights Will Be Used In The Gymnasium. These Are Integrated Into The Radiant Ceiling Panels. The Interface To The Electrical Trade Is The Power Supply And Control Via The Knx System. In Other Rooms, Control Is Via Presence Detectors.

Safety Lighting System: The Escape Sign And Safety Lights Are Supplied From Two Decentralized Emergency Power Lighting Devices (Group Battery Devices). Potential Equalization: Potential Equalization Rails Are Installed In The Areas Of The Technical Rooms, Sub-Distributions, Data Cabinets And Tga Building Technology Centers. These Are Connected To The Earthing System Via Connection Lugs Or Separate Earthing Cables To Ensure Additional Potential Equalization. All Metallic And Conductive Components Are Connected To These Potential Equalization Rails Using Potential Equalization Conductors In Order To Exclude Dangerous Body Currents. Execution Times For Empty Pipe Laying Work In Concrete: Expected Start Of Work: Week 28/ 2026 Expected Completion Of Work: Week 34/ 2026 Execution Times For Electrical Work: Expected Start Of Work: Week 1/ 2027 Expected Completion Of Work: Week 40/ 2027
