The SDX-Compact enables fast and simple acquisition of topographic data - for billing purposes as well as for supporting site management, such as material planning. It is now used regularly across a range of active construction sites.
“Using a rover or total station, this would take half a week or more. With the Sodex box, it’s done in half an hour to an hour.”
Samuel MayerHeim Bau GmbHPreviously, site surveying at HEIM was carried out using GNSS rovers or total stations – time-consuming and labor-intensive. Data was not always available when needed to support the construction team with planning or procurement decisions.
What was needed was a simple, ready-to-use solution that would speed up surveying while relieving operational pressure on-site.
HEIM now uses the SDX-Compact System, installed on its survey vehicle. Data collection takes place simply by driving across the construction area. Thanks to quick data availability and ease of use, the survey team can cover multiple sites per day. The system has proven especially effective in road construction, where large areas need to be documented quickly and efficiently.
Site Drive-Through
The terrain is captured in two passes:
First pass to document the existing (pre-construction) ground level
Second pass after earthworks to record the excavation base
The scanning is carried out without interrupting site operations – just by driving over the area with the survey vehicle.
Data Processing
After each scan, the data is automatically uploaded to the SDX-Cloud, where the office team can access and process it within a short time. Export to the existing CAD environment happens directly, enabling immediate volume calculations and planning.
HEIM’s ongoing use of the SDX-Compact System shows how modern surveying can be fully integrated into daily construction workflows. The data is available quickly, easy to analyze, and supports not just billing, but operational site decisions—from cut-and-fill tracking to asphalt logistics. It saves time, reduces miscommunication, and increases process reliability.
Surveying in minutes instead of days
Complete area coverage with immediately usable results – no preparation needed
Operational support
Site managers receive actionable data for planning and material orders
Flexible deployment
Mounted on a survey vehicle and easily used across multiple sites – ideal for efficient use of a single system
“We used to spend hours walking the site with a rover. Now we just drive once, and by the time we’re back, the data is already uploading.”
