Formula Used

Floor dead load = floor area × floor dead load.

Floor live load = floor area × floor live load.

Roof load = roof area × roof dead load + roof area × roof live load.

Wind load = wind pressure × projected wind area.

Service gravity load = floor dead + floor live + roof dead + roof live.

Contingency load = service gravity load × contingency percentage.

Factored gravity load = dead factor × dead loads + live factor × floor live load + roof factor × roof live load + contingency.

Bearing pressure = factored gravity load ÷ total footing area.

Required footing area = factored gravity load ÷ allowable soil pressure.

Support utilization = factored load per support ÷ entered support capacity × 100.

How to Use This Calculator

  1. Enter the project name, project type, and preparer name.
  2. Add floor area, roof area, and load values from plans or design notes.
  3. Enter wind pressure and projected area for a lateral load estimate.
  4. Add support count, footing area, soil pressure, and support capacity.
  5. Review or adjust load factors for the intended design check.
  6. Press the calculate button to show results below the header.
  7. Download the CSV or PDF report for records and coordination.

City of Dunedin Load Planning

A construction load review starts with clear quantities. Each room, roof plane, wall line, and support area should be measured before any number is entered. This calculator helps organize those values for early planning in Dunedin projects. It does not replace sealed structural drawings, local review, or a site-specific code check.

What the Calculator Reviews

The tool separates dead load, live load, roof load, lateral wind pressure, bearing demand, and column share. Dead load covers permanent materials. Live load covers people, furniture, storage, and movable items. Roof load combines roof surface weight and the selected roof live allowance. Wind demand is estimated from pressure times projected area. The bearing check compares foundation demand with the entered allowable soil pressure.

Why Editable Inputs Matter

Dunedin projects can vary by occupancy, location, exposure, flood zone, roof type, and structural system. A porch, garage, retail bay, and office suite may all need different assumptions. For that reason, this calculator avoids locked values. It lets designers, contractors, and owners enter the design criteria shown on drawings, notes, or engineering guidance.

How Results Should Be Used

Use the service loads to understand normal expected demand. Use factored loads for a conservative design view. Review the maximum bearing pressure before selecting a footing size. Compare the load per support with column, post, wall, or pier capacity. Keep the downloaded report with sketches, takeoff notes, and permit planning records.

Good Practices

Measure areas from accurate plans. Do not mix square feet and square inches. Check units before export. Round final values only after calculations are complete. Revisit inputs when wall locations, roof spans, use groups, or equipment weights change. For final submittals, coordinate with qualified professionals and the authority having jurisdiction. Careful load planning reduces redesign, improves documentation, and supports safer construction decisions.

Documentation Notes

A useful worksheet should show source dimensions, selected load factors, and the person who prepared the estimate. Record any assumptions about occupancy, equipment, storage, exposure, and temporary construction loads. Save each revision, because reviewers may ask why a value changed. Clear notes make future coordination faster and reduce field questions. Use the example table to compare scenarios and explain choices with fewer review delays during planning meetings.

FAQs

Does this calculator replace a structural engineer?

No. It supports early planning only. Final load paths, member sizes, connections, and foundations should be reviewed by qualified professionals when required.

Can I use it for permit preparation?

Yes, it can organize preliminary values for discussion. Always verify submittal requirements, code criteria, and official forms before filing any permit package.

Why are load factors editable?

Projects may use different design combinations or review assumptions. Editable factors let the worksheet match the values shown on plans or engineering notes.

What does bearing pressure mean?

Bearing pressure is the factored gravity load divided by total footing area. It helps compare foundation demand with entered allowable soil pressure.

What is projected wind area?

Projected wind area is the building surface area exposed to wind pressure. It is commonly based on wall, roof, sign, or equipment geometry.

Can this calculate roof replacement loads?

Yes. Enter roof area, roof dead load, and roof live load. Add notes about removed layers, new materials, and framing assumptions.

Why include contingency load?

Contingency helps account for early estimating uncertainty. It should not hide unknown conditions. Update it when accurate plans and material weights are available.

What should I save after calculating?

Save the PDF or CSV report with drawings, measurements, assumptions, and revision notes. Clear records make later review and coordination easier.
