Machine Control Modelling

Design Interpretation & Conversion

We interpret civil and architectural plans and convert them into usable formats for machine control systems. (Trimble, Leica, Topcon)

3D Terrain & Surface Modelling

Accurate 3D surface models built for real-world performance, ensuring grade correctness and constructability across all stages.

3D Linework Modelling

Precise Linework Models built for trench foundations or pipelines, helping to maximise machine productivity and site minimise waste.

Site Calibration & Setup

Coordinate System Verification

Often missed, this critical step is vital to ensuring machine control is correctly applying design coordinates to the real world.

Site Calibrations

Once the coordinate upon which the design is based has been verified, a full GNSS site calibration can be performed to ensure that digging is undertaken in the right place.

Datum Installation & Base Station Setup

GPS Machine control has many working parts, be sure that everything is working as it should by having control points that operators can check against.

Don’t wait until it’s too late.

Why not monitor the progress on GPS controlled earthworks projects by having progressive survey undertaken along the project? We can highlight differences between the as-built & design early in the programme.

Frequently Asked Questions

We hope this FAQ section has addressed some of your common questions. If you have any further queries, please don’t hesitate to reach out to us.

AJS Engineering offers Nationwide Coverage in Machine Control modelling.

The time spent modelling can vary depending on the size and detail of the model and the quality of the design information provided. We always endeavour to turn around models within 1-2 working days however on larger more complex models this cannot always be achieved.

We have multiple software licenses available to us which allows us to create machine control models compatible with Trimble, Leica and Topcon

Typically: design drawings, site control or calibration data, vertical design info (e.g. levels/sections), and any specification notes. If something’s missing, we’ll flag it early.

Absolutely. We can revise the model as new revisions are issued — often with faster turnaround than the initial build. Just send us the updated files and we’ll handle the rest.

If the design includes utilities or exclusion zones, we can incorporate them — either for display or for cut protection in the machine. Let us know your requirements and we’ll adjust accordingly.

Definitely. Whether it’s file formats, control system details, or coordinate system issues — we’re happy to work with your operator or equipment supplier to get it right the first time.
