Water Supply Analysis and Hydraulic Calculations & Codes, Standards, and Licensing Administration
Calculate sprinkler discharge pressure and flow for K=5.6, 8.0, and 11.2 at 7, 15, and 50 psi, showing every algebraic step.
Compute remote-area demand for a 1,500 sq ft light-hazard area at 0.10 gpm/sq ft and state the resulting system flow.
Apply Hazen-Williams with C=120 to 2-, 3-, and 4-inch Schedule 40 pipe at 250 gpm and tabulate friction loss per foot.
Outline Oklahoma licensing and plan-submittal requirements: licensing authority, contractor versus fitter credentials, permit sequence, and AHJ role.
Your checkpoint
One-page hydraulic worksheet containing Q=K√P examples, a Hazen-Williams friction table, and a supply-versus-demand plot for a light-hazard tree system.
Water Supply Analysis and Hydraulic Calculations & System Types and Design Criteria (Occupancy Hazard, Density/Area, Special Occupancies)
Perform a complete tree-system calculation from the most remote head through the riser, including elevation, fitting equivalent length, and device losses.
Select density/area points for light hazard, Ordinary Group 1, and Ordinary Group 2 occupancies from the NFPA 13 density/area curves and justify each choice.
Calculate flow and pressure at the hydraulically most remote head on a 12-head branch line and propagate the demand back to the supply.
Convert between gpm, psi, and feet of head, then verify a static/residual flow test against the calculated demand plus safety margin.
Your checkpoint
Completed hydraulic calculation sheet for one Ordinary Group 2 system, from remote area to supply, with a documented 10 percent safety margin check.
System Types and Design Criteria (Occupancy Hazard, Density/Area, Special Occupancies) & Sprinklers and System Components (Heads, Valves, Alarms, Flow Switches)
Classify five sample occupancies into light, ordinary, extra, and storage hazard categories and cite the governing NFPA 13 criteria for each.
Select sprinkler type, K-factor, temperature rating, and response characteristic for each classified occupancy and record the rationale.
Compare wet, dry, preaction, and deluge systems on trip time, air or nitrogen supervision, and inspection frequency.
Identify the function and acceptance-test requirement of alarm check valves, dry pipe valves, preaction valves, OS&Y valves, and butterfly indicating valves.
Your checkpoint
System-selection and sprinkler-schedule table for a mixed-use four-story building containing office, parking, and storage areas.
Piping, Fittings, Materials, and Joints & Sprinklers and System Components (Heads, Valves, Alarms, Flow Switches)
Specify pipe material and joining method for black steel, galvanized steel, CPVC, and copper across five installation scenarios, citing the applicable NFPA 13 limitations.
Size branch lines, cross mains, and risers while checking velocity and friction limits against the calculated demand.
Compute equivalent length for fittings, valves, and devices and add it to the physical pipe length for each segment.
Lay out required control valves, drains, test connections, and gauge locations on a riser diagram and label each.
Your checkpoint
Piping specification and labeled riser diagram for the four-story building, with material callouts and fitting equivalent lengths tabulated by segment.
Hangers, Restraint, and Seismic Protection & Fire Pumps, Tanks, and Water Storage
Lay out hangers and supports along a 100-foot main and branch line using NFPA 13 Chapter 17 spacing and placement limits, including zones of influence.
Design lateral, longitudinal, and four-way sway bracing for a 2,000 sq ft seismic zone and mark brace locations on a sketch.
Plot a fire pump curve at churn, rated flow, and 150 percent flow, then select a pump meeting system demand with the required pressure margin.
Calculate water storage tank capacity including fire flow, duration, and dedicated reserve for a 1,000 gpm demand.
Your checkpoint
Hanger and bracing layout sketch plus a one-page pump-and-tank selection summary with the demand point overlaid on the pump curve.
Plan Review, Permits, and Field Inspection & Acceptance Testing, Inspection, Testing, and Maintenance
Review a ten-sheet sprinkler plan set against a 25-item checklist covering hydraulic calcs, spacing, clearances, and underground coordination.
Write at least ten correction comments, each tied to a specific code or standard citation.
Build a 12-month NFPA 25 inspection, testing, and maintenance calendar covering gauges, main drain, alarm devices, flow switches, and valve exercises.
Interpret main drain and inspector's test readings against expected static and residual values and identify three common failure signatures.
Your checkpoint
Redlined plan review with ten cited comments plus a completed 12-month ITM schedule for a wet system with a fire pump.
Codes, Standards, and Licensing Administration & Acceptance Testing, Inspection, Testing, and Maintenance & Jobsite Safety and Coordination with Other Trades
Reconstruct the workflow from permit application through hydrostatic test, final inspection, and acceptance, naming each inspection hold point.
List OSHA requirements for fall protection, material lifting, and hot work that apply to sprinkler installation crews.
Sequence sprinkler rough-in against ductwork, electrical, and structural trades and identify three clash points to resolve before overhead installation.
Redo every missed question from weeks 1 through 6 and tag each by root cause: code misread, math error, or knowledge gap.
Your checkpoint
Jobsite safety and trade-coordination checklist plus an error log listing the 20 most-missed concepts with corrected explanations.
Water Supply Analysis and Hydraulic Calculations & System Types and Design Criteria (Occupancy Hazard, Density/Area, Special Occupancies) & Acceptance Testing, Inspection, Testing, and Maintenance
Take two timed 100-question practice exams under exam conditions and record section-by-section scores.
Review every missed item, locate the governing code clause, and rewrite the correct reasoning in one sentence.
Compress key formulas, density/area values, hanger spacing limits, and ITM frequencies into a single reference page.
Re-drill the two lowest-scoring domains until a 30-question spot quiz yields at least 85 percent.
Your checkpoint
Two scored practice exams with a one-page formula and code-reference sheet covering all ten domains.
Milestones
