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.
Concrete quantity calculator
Check net geometry and a separately chosen allowance before ordering concrete for an exercise. Do not hide a default waste percentage inside the volume formula.
Open tool →FREE TOOLSlope and grade calculator
Translate construction rise and horizontal run into the formats shown on drawings. Distinguish sloping surface length from horizontal station distance.
Open tool →FREE TOOLEarthwork volume calculator
Use ordered cross-sections to estimate cut and fill separately with average-end areas. Add a section at a cut-to-fill transition instead of blending unlike areas.
Open tool →FREE TOOLMaterial weight calculator
Convert a volume takeoff to material mass using an appropriate supplied density. Report gravity force separately so kilograms and newtons are not confused.
Open tool →FREE TOOLCrew productivity worksheet
Estimate clock duration from whole-crew output, then convert to person-hours. Keep crew productivity separate from productivity per individual worker.
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 Construction Tutor.
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.
