Understand the working.
Calculators and worksheets for the subjects you study and the problems you meet in practice. Work through an example, try your own values, then test the same ideas in exam practice.
Stair measurement worksheet
Record individual measurements before evaluating the range and variation. Attach the source and edition of any limits used in an inspection-training comparison.
Open tool →FREE TOOLRamp measurement worksheet
Separate longitudinal slope and crossfall in an inspection record. Document the supplied criteria without implying that slope checks cover every accessibility requirement.
Open tool →FREE TOOLDrainage slope calculator
Translate a measured pipe elevation fall and horizontal run into a drainage slope. The arithmetic does not choose the minimum permitted slope for a pipe size or installation.
Open tool →FREE TOOLOccupant load and egress arithmetic
Apply supplied occupancy and width factors to an explicitly defined area. Record the criterion source instead of choosing an occupancy classification automatically.
Open tool →FREE TOOLInspection record builder
Keep accessible observations, reference evidence and unresolved follow-up separate. An incomplete component record should remain visible instead of silently becoming a passed inspection.
Open tool →Tools that connect the calculation to the concept
Each tool shows its method, units and assumptions, together with two worked examples. Example values are for learning; replace them with your own measurements or documented inputs. The related study links take you to the matching certification topic on Inspector Exam.
Worksheets run in your browser. We do not send entered measurements or report text to a calculation service. Where export is available, you choose when to save the file locally.
Check the boundary of the answer
A useful result starts with the right inputs and an appropriate method. These tools explain what is calculated and what the method leaves out. User-supplied criteria remain identified as supplied criteria; a calculation does not automatically approve equipment, certify an inspection or establish regulatory compliance.
