A methodical investigation, documented at every step

How the investigation and documentation process works, from scoping through delivered findings.

Investigation process

From project scope to delivered record

The method serves the decision. It is not a commodity equipment checklist or a promise that subsurface uncertainty can be eliminated.

  1. 01Scope

    Understand the site, intended work, and decisions the project team needs to make.

  2. 02Investigate

    Apply field methods appropriate to the site and infrastructure in question.

  3. 03Classify

    State confidence in findings instead of presenting uncertainty as exactness.

  4. 04Document

    Deliver a defensible record in formats that fit downstream workflows.

Field methods

Precision in service of useful documentation

RTK GPS precision and ASCE 38-aligned methodology support the record. Findings are interpreted and classified, never presented as guaranteed depth or exact location.

  • Field evidence

    Located and observed directly in the field.

  • Record evidence

    Correlated with records and surface indications.

  • Verification recommended

    Flagged where further verification protects the decision.

Deliverables

Formats prepared for the way teams work

KMZ files through pre-construction intelligence reports, congestion mapping, utility maps, and verification recommendations.

  • 02Pre-construction intelligence reports
  • 03Congestion mapping
  • 04Verification recommendations
  • 05Utility maps

Decision checkpoints

What changes from scope to delivered record

The investigation becomes more useful when each handoff answers a specific question and keeps limitations visible.

Scope checkpoint
Is the work area defined, are ownership questions understood, and is the desired decision clear?
Field checkpoint
Which methods fit the site, where is access limited, and what evidence was actually observed?
Interpretation checkpoint
How much confidence can each finding bear, and where does uncertainty remain?
Delivery checkpoint
Which format will the recipient use, and what verification recommendation belongs with it?

Prepare

Make the first conversation productive

Homeowners should have a defined project address and planned work. Commercial leads should own project planning, safety, or excavation responsibility and share available site information.

  • Project address
  • Planned work
  • Area of concern
  • Available plans
  • Access constraints
  • Decision the findings must support
