WHAT WE PREPARE

Construction-focused model information.

EARTHWORKS

Ground & Formation Models

Excavation, embankment, platform, formation, subgrade, slopes, boundaries and breaklines.

ROADS

Road & Corridor Geometry

Centreline, channels, kerbs, tie-ins, crossfall, junction geometry and road formation where supported by the source design.

EXCAVATION

Dig & Trench Surfaces

Reduced levels, pits, trenches and construction surfaces prepared to an agreed design basis.

UTILITIES

Pipework / Ducting Context

3D routes and trench information can be coordinated with the model where the required levels and geometry are supplied.

SURVEY

Setting-Out & QA Data

Coordinates, points, lines, design-versus-survey information and model checks for agreed workflows.

CUSTOM

Project-Specific Output

Tell us the target software, machine-control environment and required deliverable before export.

WORKFLOW

Source information stays visible and reviewable.

01

INPUT

Drawings, survey files, sections, coordinates and project brief.

02

CHECK

Units, coordinate system, datum, levels, gradients and missing information.

03

MODEL

Build the agreed 3D geometry, breaklines and/or TIN surface.

04

QA

Review continuity, boundaries, tie-ins, levels and export structure.

05

DELIVER

Issue agreed DXF, XML/LandXML, TIN/DTM, schedules, views or report.

SYNTHETIC DEMONSTRATION

Machine-control model example.

This example uses synthetic local coordinates and levels. It demonstrates the type of information and deliverables that can be prepared without presenting fictional data as a real construction design.

RELATED EXAMPLES

Roads + earthworks + machine control.

Synthetic 3D road model

Road Model

Illustrative centreline, channel and formation geometry.

Synthetic earthworks model

Earthworks Model

Illustrative excavation, fill and terrain surface.

DEMO DOWNLOADS

Inspect the example deliverables.

Demonstration only: these downloadable files use synthetic data. They are not approved construction information and must not be used for setting-out, machine guidance, valuation, permits or site work.

DELIVERABLES

Agree the target before export.

DXF

3D CAD Geometry

3D polylines, breaklines, boundaries, points and structured layers.

XML / LANDXML

Surface / Alignment Data

Supported TIN surfaces and model information for compatible downstream workflows.

TIN / DTM

Construction Surfaces

Formation, excavation, earthworks or design surfaces prepared to the agreed scope.

CSV / TXT

Survey Data

Coordinates, levels and schedules where required.

PDF / JPG

QA & Review

Model views, summaries, checks and supporting documentation.

CUSTOM

Target Workflow

Confirm the machine/control system, software version and expected file structure before delivery.

FAQ

Before we prepare a model.

Can you convert any PDF directly into a machine-control model?

No. A usable model depends on the quality and completeness of the source design. Coordinates, levels, geometry, sections and the intended construction layer must be established rather than guessed.

Do you provide LandXML?

LandXML/XML can be prepared where the model and target workflow support it. The required surface, alignment and downstream system should be agreed before export.

Can you prepare models for excavators and dozers?

We can prepare construction model information for compatible machine-control workflows. Final compatibility and field use must be confirmed against the specific system, project requirements and approved design.

What files can I send?

Typical inputs include PDF, DWG/DXF, XML/LandXML, survey CSV/TXT, coordinates, sections and written scope information.

How do you deal with missing levels?

Missing or unclear design information is identified during review. Engineering levels or design intent are not silently invented.

START A PROJECT

Send your drawings for review.

Tell us what you have, what you need and the intended machine-control or survey workflow. We can then define the model scope and deliverables.
