Survey-Experienced

Practical field and office judgment behind every deliverable.

Full Data Workflow

Models, surfaces, CAD, LiDAR, and supporting survey information.

Built for Your Team

Flexible support for contractors, surveyors, and engineers.

Clear Deliverables

Prepared files, issue logs, and findings your team can act on.

Core Services

Construction models and surfaces you can build on

Approximately two-thirds of DatumLine’s work is focused on 3D model creation, verification, and machine-control readiness. Those services receive the strongest emphasis throughout every project workflow.

01

3D Construction Model Creation

Create clean, coordinated surfaces, breaklines, and staged model packages from design plans, CAD, survey, and supporting project data.

  • Roadway and site surfaces
  • Breaklines and grading features
  • Model staging and file organization
02

Model Verification & Surface Comparison

Compare contractor, design, survey, and existing-ground datasets to identify gaps, mismatches, and unexpected differences.

  • Difference mapping and review
  • Missing or conflicting feature checks
  • Documented findings and recommendations
03

Machine-Control Readiness

Prepare and organize construction data for dependable field use, with a practical review of supporting information and likely risk areas.

  • Model package review
  • Coordinate and localization notes
  • Readiness checklists and issue logs

Supporting production services

LiDAR & Point-Cloud Surfaces

Process, classify, and derive practical terrain and design-support surfaces.

Survey CAD & Data Processing

Clean, organize, and standardize survey and civil production files.

Legal Description & Plat Review

Flag inconsistencies, ambiguities, and record-versus-drawing discrepancies.

Overflow Production Support

Add experienced capacity when project teams are overloaded or behind schedule.

How DatumLine Helps

Find problems in the data before they become problems in the field

A deliverable is only useful when the people relying on it can understand it, trust it, and use it without unnecessary uncertainty.

  • PrepareBuildable surfaces and organized model packages.
  • CompareDesign, contractor, survey, and existing-ground datasets.
  • IdentifyMissing, conflicting, or incomplete project information.
  • DocumentDiscrepancies, risk areas, and recommended next steps.
  • CoordinateCAD, LiDAR, survey, and construction-data workflows.
  • SupportInternal teams when production capacity is limited.

Workflow

A clear, accountable production process

  1. 01

    Project Intake

    Share plans, design files, survey data, and the project objective.

  2. 02

    Risk Screen

    Review file condition, confirm scope, and flag missing information.

  3. 03

    Create or Compare

    Build, refine, compare, or review the required construction data.

  4. 04

    Document Findings

    Provide prepared files, issue logs, comparison results, and recommendations.

  5. 05

    Refine & Support

    Complete revisions and support the project’s next phase as needed.

About DatumLine

Experienced judgment behind every deliverable

DatumLine Solutions is led by Eric Roth, PLS, a licensed land surveyor with more than 30 years of experience in surveying, public works, CAD, construction data, right-of-way, surface modeling, legal-description review, and project production.

That background brings practical field and office perspective to every model, comparison, and data package—helping clients catch problems early and move forward with clearer information.

Professional Review & Responsibility

DatumLine provides production support, technical review, comparison, and issue identification. Final design responsibility, certification, boundary interpretation, agency approval, and construction decisions remain with the appropriate licensed professional, client, contractor, or reviewing authority unless otherwise defined in a written agreement.
