LandPlan Land Surveyors - CAD Draughting & 3D Modelling

Modelling & Draughting

CAD Draughting, 3D Modelling & Scan-to-BIM Services

At LandPlan, our service doesn't end in the field. We transform raw spatial data into high-value digital assets.

Our in-house team - including professionally registered architects - utilizes advanced processing software to deliver precision BIM models, architectural plans, and engineering drawings tailored to your project’s specific software environment.

Industry-Standard CAD & Engineering Exports

We provide seamless data integration for civil contractors and design firms, delivering high-accuracy outputs in the following specialized formats:

Vector Drawings: Native DWG and DXF files optimized for AutoCAD and Civil 3D.
ModelMaker Integration: We produce TOT and MAL files specifically for ModelMaker and RoadMaker users.
Digital Plans: Professional PDF plans ready for municipal submission and site use.

High-Density Point Clouds & 3D Reality Capture

For projects requiring high-resolution "digital twins," we process billions of data points into manageable, georeferenced files:

Point Cloud Formats: Full support for LAS, LAZ, E57, RCP, and RCS datasets, perfect for Revit BIM modelling and structural analysis.
Volumetric Analysis: 3D surface modelling for accurate earthwork and stockpile calculations.

Georeferenced Aerial Imagery & GIS Data

Our aerial survey division produces crystal-clear, georectified ortho-images that serve as the definitive site overview:

High-Definition Orthophotos: Delivered in GeoTIFF, ECW, and JPG formats for high-resolution site mapping.
GIS Ready: Data formatted for immediate use in ArcGIS and QGIS platforms.

In-House Architectural BIM Modelling

Unlike standard surveying firms, LandPlan offers in-house architectural expertise.

Our registered architects can take raw survey data and develop full BIM (Building Information Modelling) objects, ensuring that your as-built or topographical data is perfectly aligned with architectural design standards from day one.

Draughting and modelling for clients across South Africa

LandPlan's draughting and BIM team works from Lynnwood Glen, Pretoria and Kleinmond in the Western Cape, supporting architects, engineers and contractors in Pretoria, Johannesburg, Centurion, Midrand, Cape Town, Stellenbosch and across South Africa.

Frequently asked questions

Which file formats do you deliver?

DWG, DXF, PDF, Revit (RVT), point clouds (LAS, LAZ, E57, RCP, RCS), ModelMaker TOT and MAL files, and GIS data for ArcGIS and QGIS.

Can you create a Revit model of an existing building?

Yes. We laser scan the building and our in-house team, including registered architects, builds an accurate Revit BIM model from the point cloud.
