Learn how automatic sprinklers extinguish fires using a heat-sensitive glass bulb or fusible link, NFPA 13 classifications (k-factor, temperature rating, thermal sensitivity, orientation), and installation considerations.

Explore firefighting water tanks per NFPA 22, including bladder, break, gravity, and suction tanks, their materials, sizing, and integration with pumps and maintenance considerations.

Link architectural and structural models in the firefighting rivet file using manage links and origin to origin, aligning internal origin, project base point, and survey point for accurate coordination.

Learn to create and manage levels and grids in Revit for firefighting projects, including copying levels from architectural links with copy monitor and managing visibility and isolation.

Create 2d views for firefighting systems across floors, including sprinkler and firehose reel cabinet, and manage view ranges and templates to ensure consistent sheets export.

Tag architectural rooms and shafts in revit mep to set up firefighting systems, then assess travel distance, exits, and dead-end corridors for life-safety compliance.

Learn to set up firefighting pipes in Revit MEP by applying red steel schedule 40 and using threaded fittings below 50 mm, or victoric grooved and welded fittings above.

Apply NFPA 5000 to classify occupancies, determine sprinkler needs, and plan installation across basement, ground, first, and second floors, using most restrictive requirements for mixed occupancy.

Explore NFPA 13 based installation requirements for fire sprinklers, including spacing between sprinklers and walls, protection area calculations, hazard classifications, and a focus on wet systems.

Learn to distribute sprinklers in large open areas like car parking using protection-area method 4 by 3, choosing upright or sidewall sprinklers, and adjusting coverage, elevations, and distances.

Learn how zone control valves isolate each floor in NFPA 13 compliant firefighting systems, install auxiliary drains, flushing valves, and air vents to ensure drainage and inspection readiness.

Explore the manual standpipe system under NFPA 14, including standpipe definitions, hose connections, and cabinet types, and distinguish class 1 and class 2 configurations.

Design class 2 fire hose cabinets to provide 100 gpm at 4.5 bar to the most remote cabinet per NFPA 14, with accessible, non obstructing locations.

explains class 1 standpipe design per NFPA 14, with 2.5 inch hose connections on landings, 36 m travel, 4 in vertical, 2.5 in branch, and 6.9 bar residual pressure.

Describe how the fire department connection, or siamese connection, delivers supplemental water to class 1 and sprinkler systems based on system demand.

Master class 2 hydraulic calculations within Revit MEP for firefighting design, aligning with NFPA standards and Elite project workflows.

Perform class 1 hydraulic calculations to determine pressure and flow for the remote two 2.5 inch cabinets, achieving 6.5 bar residual pressure with a 500 gbm pump at 9.5 bar.

Master sprinkler hydraulic calculations and summarize calculation methods within Revit MEP fire fighting workflows, aligned with NFPA standards and Elite design practices.

Select and verify fire pump performance by reading the pump curve, meeting NFPA 20 criteria at 150% and zero flow, ensuring system demands lie below the curve.

Size suction and discharge headers for NFPA 20 fire pumps, using 150 mm (6 in) when 5 in is unavailable, to meet a 500 gbm rated flow, modeled in Revit.

Explain NFPA 20 pump installation rules: maintain a suction spacing of 10 pipe diameters to ensure laminar flow and prevent cavitation, and use eccentric reducers for suction from same level.

Design and configure a fire pump test line in Revit MEP. Connect to the discharge header, place two butterfly valves and a flow meter with 5D and 2D spacing.

Learn to select and place a pressure relief valve for a diesel pump, determining inlet and discharge sizes, and evaluating 121% net shut-off pressure plus static suction against 12.1 bar.

Place outside screw and yoke valve on the suction side to reduce pressure drop and cavitation, install a discharge check valve, and add alarm check valve for wet pipe systems.

This lecture explains the bodily flange around a pipe through a wall to prevent leakage and the NFPA 20 anti-vortex plate to prevent pump cavitation, with placement and sizing.

Calculate diesel tank capacity as 1 gallon per horsepower plus 5% expansion and 5% sump, model a 70 gal tank and 30 cm dike in Revit with black steel piping.

Explore sensing lines and control panels for fire pumps under NFPA 20, linking pressure sensing lines to transducers and three electrical panels, with pipe specifications and check valve requirements.

Calculate fire protection water volume using the highest flow of 500 gpm and the longest duration for standpipe and sprinkler systems, then visualize two tanks in Revit for pipe sizing.

Design tank piping for firefighting systems, sizing the filling line and overflow per NFPA 22. Include drain and vent pipes, valves, and floating valve mechanism in Rivet.
