Detailed service scope

Choose the work.
Define the result.

A closer look at each service group. Outputs depend on the supplied information, agreed scope and target workflow.

01

Earthworks & excavation

Bring existing ground and design levels together in a clear, structured terrain model.

Scope
Excavations, embankments, formation, subgrade, slopes, benches, platforms and stockpiles.
What to send
Survey surfaces, design levels, boundaries, sections and the required construction layer.
Possible outputs
Agreed TIN/DTM surfaces, breaklines, DXF or LandXML and supporting volume information.
Review note

Volume comparisons need a common valid boundary, compatible coordinates and an accepted surface basis.

02

Roads & infrastructure

Turn road layouts, levels and sections into usable 3D construction geometry.

Scope
Centrelines, channels, kerbs, crossfalls, tie-ins, junctions, access roads, parking and footways.
What to send
Plan layouts, design levels, cross-sections and confirmed tie-in information.
Possible outputs
3D lines, breaklines, surfaces, alignments and setting-out information to the agreed scope.
Review note

Levels and transitions are checked against supplied design information; missing design intent is raised for review.

03

Pipework, ducting & drainage

Coordinate service routes and the excavation information that supports them.

Scope
Pipework, duct banks, utility corridors, storm and foul drainage, manholes, branches and trench formation.
What to send
Layouts, pipe sizes, invert or other reference levels, gradients and cross-sections.
Possible outputs
3D routes, trench or formation surfaces, setting-out information and coordination views.
Review note

Invert, centreline and crown levels must be distinguished. Clearances and pipe dimensions require verified references.

04

Foundations & structures

Make structural plans and levels easier to interpret and set out.

Scope
Foundations, slabs, bases, plinths, retaining elements, pumping stations and platforms.
What to send
Structural drawings, dimensions, coordinates and approved level references.
Possible outputs
3D geometry, points, lines, level schedules and agreed construction sketches.
Review note

This is model preparation from supplied design, not a substitute for structural design or approval.

05

Survey, setting-out & QA

Turn field observations into organised site information and reviewable evidence.

Scope
GNSS and total-station data, points and lines, coordinate workflows, setting-out, deviations and progress surfaces.
What to send
Survey CSV/TXT, design files, control information, grid, datum and relevant tolerances.
Possible outputs
CAD geometry, coordinate schedules, comparison views and agreed QA reports.
Review note

Like-for-like references and approved tolerances are needed before a deviation can support acceptance.

06

Machine control & CAD workflows

Prepare the right data for the next software, survey or machine-control step.

Scope
Excavator, dozer and grader model preparation, CAD processing, data conversion and AI-assisted reporting workflows.
What to send
Approved geometry, the required construction layer, target software or equipment and export requirements.
Possible outputs
Supported DXF or XML/LandXML geometry, organised data and project-specific automation where agreed.
Review note

Export suitability is confirmed for the target system. A file extension alone does not establish compatibility.

Deliverables

Useful beyond
the model.

Agree the coordinate system, units, reference levels and intended software or machine-control system before file preparation.

This website describes deliverable options. It is not an online CAD conversion or model-export tool.

DXF

CAD geometry

Agreed points, 3D polylines, breaklines, boundaries and organised layers.

XML / LandXML

Structured model exchange

Supported surfaces and alignments, matched to the intended downstream system.

TIN / DTM

Construction surfaces

Terrain, formation, excavation or design surfaces to the agreed layer and boundary.

CSV / TXT

Field and schedule data

Agreed coordinates, levels, points and measurement schedules.

PDF / JPG

Reports and model views

Supporting reports, QA views and construction information included in the scope.

Custom

Other requirements

Name the target software, instrument or workflow so the required data can be reviewed.
