Ontario Construction Surveying Services

We help builders and project managers minimize errors, stay compliant, and keep construction moving with confidence.

About Construction Surveying

Every successful build starts with accuracy. From layout to completion, our construction survey services ensure your project follows plan specifications and meets municipal and engineering requirements at every stage.

At Monument-Urso Surveying, we work alongside developers, contractors, engineers, and project managers to deliver precise, regulation-ready surveys that support efficient timelines and reduce costly mistakes.

Construction Layouts

Before construction begins, Layout Surveys ensure everything is in the right place. We translate plans into real-world site markings so your crew can execute every element exactly as designed.

We lay out:

  • Excavation points

  • Gridlines and benchmarks

  • Foundation positions

  • Grade levels and slopes

  • Utilities, sidewalks, curbs, and other key infrastructure

As-Built Surveys

Once construction is complete, an As-Built Survey confirms that what was designed matches what was built. These surveys capture exact locations and dimensions of:

  • Structures

  • Roads

  • Utilities

  • Retaining walls

  • Property line encroachments


As-builts are often required for municipal approvals and record drawings. We deliver them with precision and clarity so you can validate compliance, identify deviations, and close out the project with confidence.

Control Surveys

Control Surveys create a network of permanent, high-accuracy points used as a reference throughout your project. These are critical for:

  • Large-scale construction and infrastructure builds

  • Ongoing site development

  • Mapping and data consistency across multiple survey teams


By establishing a consistent coordinate system, we ensure every measurement and phase is grounded in the same framework, avoiding costly rework later on.

Quantity Calculations

When material volumes matter, precision is everything. Our Quantity (cut/fill) Calculations help you manage earthwork and excavation with clarity. We help determine:

  • How much soil, rock, or sand needs to be removed or added

  • Differences in elevation between phases of the project

  • Total material volume for budgeting, logistics, and compliance


These surveys are especially valuable for contractors and engineers managing grading, backfill, or site balancing.
