Design conformance & as-built verification: Catch issues early, close with confidence
Compare surveyed site conditions with approved designs throughout the project. Identify grade and volume differences, coordinate next steps, and build a dated record to support as-built verification and phase closeout.
Catch design differences throughout the project
Bring in the design. Confirm the approved revision and alignment with your survey.
Compare current conditions. Identify elevation differences and quantify cut/fill.
Review and act. Inspect measurements and cross-sections; share findings with the team.
Repeat as work progresses. Compare updated surveys against the design.
Document the result. Retain dated surveys and export measurements and reports for closeout review.
The tools that support each step
Bring designs into context, measure differences, and share the results with the people completing and reviewing the work.
Design overlays
View supported designs alongside surveyed conditions so teams can understand the planned work in site context.
Surface comparison
Compare survey and design surfaces to locate elevation differences and quantify cut/fill within the area you select.
Grade checks
Review surveyed elevations against design levels to identify locations needing attention—not a new field measurement.
Cross-sections
Inspect survey and design profiles along roads, pads, and benches to understand differences before coordinating corrective work.
Reports and exports
Share measurements and export reports to support progress discussions, as-built documentation, and closeout review.
Explore a new option when site conditions change
When a comparison reveals a need to rethink the approach, use Propeller CAD to create a preliminary road, ramp, or pad concept on your survey terrain. Refine the idea and share it for qualified review before detailed engineering or field use.
Tailored value for every stakeholder
Different roles need different answers. Give office, field, and leadership teams a shared view of survey data, design comparisons, and results.
Project managers
Review differences against the plan, coordinate next steps, and use measurements and reports to support payment discussions and phase closeout.
Foremen and superintendents
See where work needs attention, review findings with the office, and give crews a shared visual reference for the next task.
VPs and owners
Review progress against design and use documented results to inform handover discussions and understand where further review is needed.
Surveyor and GIS leads
Check survey quality, coordinate alignment, and the approved design revision so the team starts with a suitable comparison.
Site engineers
Inspect grade and volume differences, review cross-sections, and share findings with the people coordinating and checking the work.
What supports the workflow
Bring survey data, designs, measurements, and reports together so office and field teams can check the work and document the results.
Propeller Platform
Bring surveys, designs, measurements, timelines, and reports into one workspace so teams can check work against the plan and document results.
Drone and hardware integrations
Use a supported survey workflow to capture site conditions. Check data quality and coordinate alignment before comparing the survey with design.
Propeller Mobile app
View surveyed conditions and design overlays from your phone so field and office teams can review the same site information.
Design conformance workflows by industry
Construction and civil infrastructure
Compare surveyed roads, pads, and embankments with design surfaces. Identify grade and cut/fill differences, then share measurements and reports to support corrective work and handover review.
- Compare surveyed surfaces with design to locate deviations
- Use cut/fill quantities to support billing discussions
- Measure remaining earthwork against the design
- Give office and field teams the same comparison view
Mining
Compare surveyed excavation, bench elevations, and rehabilitation surfaces with the mine plan. Use vertical differences and cross-sections to identify areas needing review.
Use case: Rehabilitation conformance
Compare surveyed landform elevations with rehabilitation designs and share the results to support professional review.
- Compare stripping and overburden volumes with design
- Review bench elevations and survey/design profiles
- Compare rehabilitation surfaces with final landform designs
- Export reports for milestone and closeout review
Aggregates and quarries
Compare surveyed excavation and bench elevations with the quarry design. Use cut/fill measurements and cross-sections to review differences and document progress.
- Compare excavation volumes with the design
- Review surveyed bench elevations against plan
- Inspect survey and design profiles in cross-section
- Share measurements and reports for progress review
Waste management
Compare surveyed cell-base and closure-surface elevations with design. Use measurements and cross-sections to identify differences for further review.
Use case: Landfill closure
Compare surveyed cover and drainage-surface elevations with closure designs to support documentation and professional review.
- Compare surveyed cell-base elevations with design
- Measure cut/fill differences across closure areas
- Review survey and design profiles in cross-section
- Export reports to support closure review
Transportation
Compare surveyed roadway and subgrade elevations with design surfaces. Share cut/fill measurements and cross-sections so crews and reviewers can assess differences along the project.
Use case: Agency review
Share survey comparisons, measurements, and cross-sections to support agency review and submittal preparation.
- Compare surveyed earthwork with design grades
- Review subgrade elevation differences by area
- Track survey progress across active work fronts
- Export reports to support agency review
- Share measured results with owners and reviewers
Check design conformance with each survey.
Compare surveyed conditions with approved designs, quantify grade and volume differences, and share results to support closeout review.
Frequently asked questions
It is a repeatable process of comparing surveyed conditions with approved designs, identifying differences, and documenting results. In Propeller, surveys, design overlays, surface comparisons, cross-sections, and reports support as-built documentation and professional review—not automatic certification.
Propeller CAD helps you explore preliminary earthworks concepts on real survey terrain. Design conformance tools compare surveyed conditions against the approved design. Creating or comparing a CAD concept does not make it approved for construction; revisions still need the appropriate engineering review and project approval.
Check survey quality, the approved design revision, and horizontal and vertical coordinate alignment. Compare the survey and design surfaces, then review heatmaps, quantities, and cross-sections to identify differences needing attention.
Use supported design surfaces for quantitative comparison and reference overlays for visual context. Confirm the file’s contents and compatibility before measuring; an accepted file format does not mean every tool applies. File types include DXF, LandXML, TTM, IFC, PDF, KML/KMZ, and supported Trimble design surfaces.
Select the survey and design surfaces within your comparison area. Review vertical cut/fill differences in the heatmap and quantities, then inspect survey and design profiles in cross-section.
Yes. Review successive survey dates against the design to track progress and retain a dated record of surveyed site conditions.
Propeller supports local site coordinate workflows. Your survey professional should confirm the project’s horizontal and vertical references and validate survey/design alignment before comparison.
Measurements, survey comparisons, and PDF reports can support quantity reviews, payment discussions, and change-order conversations. Acceptance depends on project requirements and professional review.
Set the survey and comparison cadence with your project and survey teams, based on work stages, required tolerances, and risk. Recheck after design changes and before work is covered.
