Green Check

Know before you build

Green Check helps engineering teams identify potential discrepancies between engineering design intent and project drawings before they become costly project issues.

Assistive design-to-drawing validation for structural engineering.

DESIGN + DRAWING VALIDATED EVIDENCE REVIEWED CORRECTIONS

Green Check supports engineering review. It does not replace professional judgement.

Engineering checking should not depend on finding every difference manually

  • Design intent is distributed across models, calculations, outputs, drawings, notes, and conventions.
  • Drawing checking often depends on experienced engineers manually reconstructing relationships.
  • Member labels may differ even when geometry and engineering intent are equivalent.
  • Small inconsistencies may remain hidden until late review, procurement, fabrication, or construction.
  • Green Check exists to make the comparison more structured, traceable, and reviewable.

Green Check was built to reduce uncertainty—not engineering judgement.

From design intent to reviewable evidence

Matching must not depend only on member names or numbers. Green Check compares geometry, arrangement, section characteristics, location, and engineering equivalence where appropriate.

  1. 01

    Engineering Design

    The starting point: the engineering design as intended by the design team.

  2. 02

    Structured Extraction

    Design and drawing information is extracted into a structured, comparable form.

  3. 03

    Geometric and Engineering Understanding

    Extracted information is interpreted as engineering geometry and arrangement, not raw text.

  4. 04

    Design-to-Drawing Matching

    Design intent and drawing representations are matched by geometry and equivalence, not by label alone.

  5. 05

    Rule-Based Validation

    Configured, deterministic engineering rules are applied where rules are the appropriate basis for a check.

  6. 06

    Evidence-Backed Findings

    Each finding is attached to the design and drawing evidence it was compared against.

  7. 07

    Engineer Review and Disposition

    A qualified reviewer examines each finding and records a disposition.

  8. 08

    Validation Report

    Reviewed findings and dispositions are compiled into a validation report.

Structured checks across design and drawing information

Layout and Arrangement

Checks whether expected structural members and layouts are represented in the drawing.

Geometry and Member Matching

Compares location, orientation, overlap, offsets, dimensions, and equivalent member relationships.

Sections and Dimensions

Identifies differences in member sizes, sections, levels, and relevant dimensional information.

Reinforcement and Detailing

Surfaces differences in bars, spacing, quantities, detailing, and represented reinforcement intent where supported.

Drawing Completeness

Identifies missing information, unmatched members, incomplete details, and conditions that prevent dependable checking.

Code- and Rule-Based Observations

Applies configured deterministic engineering rules and clearly identifies the source and basis of each observation.

Cross-Document Consistency

Checks whether connected engineering information remains consistent across relevant design and drawing representations.

Available checks depend on the input documents, extraction confidence, configured rule pack, and project context.

Findings engineers can examine—not unexplained answers

Where available, each finding presents what was compared, what Green Check found, the source design and drawing evidence behind it, the applicable rule or comparison basis, a severity and confidence level, a recommended review action, and space for the reviewing engineer's own disposition and notes.

Built around engineering accountability

01

Evidence Before Conclusions

Every finding should be supported by traceable comparison evidence.

02

Deterministic Rules Where Rules Matter

Code checks and defined engineering validations should remain explicit and reproducible.

03

Uncertainty Is Visible

Green Check should distinguish confirmed differences, uncertain matches, incomplete inputs, and conditions requiring investigation.

04

Engineers Remain in Control

Qualified professionals review, disposition, and act on the findings.

Green Check does not approve drawings or assume the responsibility of the engineer of record.

Current focus — RC structural validation

Focused scope. Transparent limitations.

  • Green Check is initially focused on reinforced-concrete structural design-to-drawing validation.
  • Input quality directly affects extraction and checking quality.
  • Some findings may require manual confirmation.
  • Unsupported or uncertain conditions are surfaced rather than silently inferred.
  • Project-specific conventions and rule configurations may require calibration.
  • The engineer of record remains responsible for final engineering decisions.
  • Broader disciplines and formats are not claimed until they are validated and released.

Questions engineering teams usually ask

Does Green Check replace the drawing checker or engineer of record?

No. Green Check supports the drawing checker and engineering team by surfacing potential discrepancies for review. The engineer of record and checking engineer remain responsible for professional judgement and final decisions.

What design and drawing information can Green Check currently use?

Green Check is initially focused on reinforced-concrete structural design-to-drawing validation, using structured design and drawing information relevant to that scope. Supported inputs are confirmed for each project during pilot scoping.

Does member matching depend on identical names?

No. Matching is intended to compare geometry, arrangement, section characteristics, and location, not only member labels, since member names may differ even when engineering intent is equivalent.

How does Green Check handle uncertain or incomplete information?

Uncertain matches, incomplete inputs, and conditions that prevent dependable checking are intended to be surfaced clearly rather than silently inferred, so a reviewing engineer can decide how to proceed.

Can project-specific engineering rules be configured?

Rule packs and comparison logic can be configured to reflect project-specific conventions. The applicable configuration is agreed as part of pilot scoping.

What appears in a Green Check finding?

Where available, a finding presents what was compared, source design and drawing evidence, the applicable rule or comparison basis, severity, confidence, a recommended review action, and space for the reviewer’s disposition and notes.

How is project information handled?

Pilot scope, supported inputs, and information-handling arrangements are agreed with the participating organisation before the project begins.

What does a pilot engagement involve?

A pilot begins with understanding your project, available inputs, checking priorities, and success criteria, followed by an agreed pilot scope, validation, engineering review, and a discussion of findings and next steps.
