Basement Fire Fighting Layout Drawing With Sprinkler And Hose System

This AutoCAD DWG file presents a detailed basement firefighting layout drawing designed for an industrial facility with complete sprinkler and fire safety coordination. The drawing shows the basement floor plan set at minus 3200 finished floor level with a grid layout and clearly spaced sprinkler heads arranged at regular 3000 mm intervals for uniform fire coverage. The system includes upright sprinklers connected to branch pipes and a main pipe routed below beams as per site conditions. Pipe diameters are defined based on sprinkler quantity, ranging from 25 mm branch connections to 150 mm fire hydrant and down-comer pipes. Fire hose cabinets sized 1200 x 600 mm are positioned at strategic points with fire hose reels, landing valves, pressure gauges, and hose holders for quick access. The layout also includes CO2 fire extinguishers of 4.5 kg and ABC powder extinguishers of 4 kg placed near circulation zones and service cores. Typical pipe support details for single pipes at ceiling level are included along with legends defining valves, supports, and flow switches. Staircases, lift cores, and service rooms are coordinated with the firefighting network to maintain clearances and compliance.
