Measurements

Why measurements matter

Measurements control almost every cost. If the area is wrong, the entire estimate is wrong. Always measure before you price.

Measurement methods

SurfaceIQ supports three methods. Use the best available method in this order:

1. On-site measurements (manual shapes)
2. Map measurement (if you cannot access the site)
3. CSV import (bulk or pre-calculated)

Manual shapes (recommended)

Rectangle

Use for simple driveways, lots, or pads.

• Length and width in ft, yd, or m.
• The system converts everything to feet internally.

Circle

Use for round islands or circular pads.

• Enter radius (not diameter).

L-shape

Use for L shaped driveways or pads.

• Outer length and width.
• Cutout length and width.

Polygon

Use for irregular shapes.

• Add points in order around the perimeter.
• Minimum 3 points.
• Use consistent units.

Map measurement

Map measurement is useful when you cannot take physical measurements.

1. Click points around the perimeter of the area.
2. Use at least 3 points.
3. The map creates a polygon and calculates area.
4. Use the displayed total to estimate.

Tips:

• Zoom in to reduce placement error.
• Click corners, not curves.
• If the shape is complex, add more points.

CSV import

CSV is best for advanced users or when you have measurements from another tool.

CSV format

type,dimension_1,dimension_2
rect,100,40
circle,15
lshape,80,40,20,15
polygon,0 0;50 0;45 30;0 30

Rules:

• One shape per line.
• Use rect, circle, lshape, or polygon.
• Polygon uses point pairs separated by semicolons.

Common measurement mistakes

• Mixing feet and yards in one project.
• Using radius when the tool expects diameter.
• Not including apron or transitions.
• Estimating by eye instead of measuring.

Accuracy checklist

• Walk the site if possible.
• Confirm each dimension twice.
• Include any extra paving for turnarounds or access.
• Keep a photo in the project so you can justify the measurement later.
