Volume & Earthworks Surveys

Stockpile Volume & Earthworks Surveying

Geo Vision Surveying Inc provides earthworks surveying and volume calculations for contractors, excavators, aggregate yards and developers across Southern Ontario. We measure stockpiles, excavations and site surfaces so your team can work from measured quantities instead of estimates. Our most recent volume job was a landfill volume project at Mountain Road in Niagara.

Volume surveys are scoped around the areas, materials and dates you need measured. The survey method, reporting and timing are confirmed before work begins.

What’s Included

Stockpile Volumes

We measure the surface of each stockpile and the ground it sits on, then calculate the volume of material. Repeat surveys can be compared between visits to track material brought in or removed.

Cut and Fill Calculations

We compare existing ground with a design surface, or with a later survey, to calculate cut and fill quantities for an area of work. Design surfaces are taken from the drawings or data supplied by your engineer or designer.

Earthworks Quantity Checks

Independent measurements let you check excavated, placed or removed quantities against estimates and design figures before work is signed off or invoiced.

Pre- and Post-Excavation Surface Comparisons

We survey the ground before excavation starts and again when the work is complete, so the difference between the two surfaces can be calculated for the agreed area.

Progress Measurements for Contractors

Repeat surveys at agreed stages show how much material has been moved to date, to support progress tracking and interim quantities as the job moves forward.

What You Receive

Deliverables are tailored to each project and provided based on your request, typically CAD drawings and a PDF volume report.

How It Works

1. Tell us about the site. Send the site location, the areas or stockpiles to measure, any design drawings or earlier survey data, and your dates.
2. We confirm the scope and method. We agree the areas, survey dates, reporting and the measurement method that suits the site.
3. We survey the site. We measure existing ground, stockpiles or excavated surfaces on the agreed dates, with repeat visits scheduled where your project needs them.
4. We calculate and report. We compare the surfaces, calculate the volumes and deliver the results your project requested, typically CAD drawings and a PDF volume report.

Survey Methods

Most stockpile work is done by total station and GPS/GNSS, typically for dirt, gravel or stone on site. Drone surveying and SLAM LiDAR scanning are available on request where the site is suitable. We review site access and the area to cover before the method is confirmed.

Who It’s For

• Contractors who need earthworks quantities and progress measurements during construction.
• Excavators who need ground surveyed before and after excavation.
• Aggregate yards that need stockpile volumes measured and compared between visits.
• Developers who want independent quantity checks on site development work.

Volume work often starts with a topographic survey of existing ground and links with grading surveys and grade checks during construction.
