Stockpiles are estimated
Surveys happen monthly or quarterly. Between them, inventory is a calculation that drifts from the ground.
Material Tracking for Mining and Construction
Mined, moved, delivered, installed. Measured at every step.
CRATUS tracks material on mine sites, quarries and construction projects with ASSET-Rx: what was mined or delivered, which truck moved it, where it is stored and how much is left. LiDAR measures stockpiles and loads, tags and GPS track trucks and loaders, and every movement is reconciled to production, shipments and job cost.

The challenge
Why material is hard to account for.
Material is moved in large quantities by many machines, and most of it is never weighed twice.
Loads are counted, not measured
Load counts and nominal payloads hide short loads, carry-back and material sent to the wrong pile.
Delivered material wanders
On construction sites, rebar, precast and prefab arrive, get moved and get lost, and crews wait or reorder.
ASSET-Rx measures stockpiles and loads with LiDAR, tracks every haul and delivery, and reconciles the numbers to production, shipments and job cost every day.

Side by side
Material tracking methods compared.
ASSET-Rx measures volume directly and tracks every move between measurements.
| Periodic surveys and tickets | Fleet management only | ASSET-Rx | |
|---|---|---|---|
| Stockpile volume | Monthly or quarterly | No | Measured by LiDAR, as often as needed |
| Load quantity | Scale tickets or nominal | Payload estimate | Measured volume, reconciled to scales |
| Material location | Site drawings | Truck position only | Pile, laydown and zone |
| Haul cycles | Load counts | Yes | Yes, linked to source and destination |
| Construction deliveries | Delivery tickets | No | Tagged and located on site |
| Reconciliation | Month end | No | Daily, by material and source |
General characteristics of each method. Dust, rain and snow affect LiDAR; installations include protection and placement to account for it.
Our approach
Measure, track, reconcile, act.
LiDAR, tags, connectivity, software and AI, engineered as one system by one team.
Measurement
LiDAR measures stockpiles in sheds, domes and open yards, and loads in truck beds, rail cars and on conveyors. Volume converts to weight with your material density and is checked against scales.
- Static stockpiles
- Volume in motion
- Weight from density
Tracking
GPS on haul trucks, UWB and BLE tags on loaders and at load and dump points, and tags on delivered construction material. Each move is logged with its source and destination.
- Haul and load cycles
- Source and destination
- Delivered material by zone
Software & dashboards
Inventory by material and pile, cycle reports, delivery status and daily reconciliation to production, shipments and job cost. Data flows to ERP, fleet and SCADA systems through APIs.
- Inventory by pile and material
- Daily reconciliation
- ERP and SCADA integration
AI
AI flags short loads, wrong-pile dumps and stock drift, forecasts when piles run low or full, and detects equipment and people with ASSET-Rx EDGE vision.

- Stock level forecasts

- 02
Measurement plan
LiDAR positions for piles and loads, tags and gateways for tracking.
- 03

Standards & practices
Planned around the requirements you work to.
Installations follow the safety, asset management, radio and cybersecurity requirements that apply to the site.
- MSHA 30 CFRMine safety and health
- OSHA 1926Construction safety
- ISO 55000Asset management
- ISO 19650Information management on construction projects
- ISO/IEC 24730Real-time locating systems
- IEC 60825-1Eye-safe laser classes
- ISA/IEC 62443Security for industrial networks and devices
- IEC 60529Ingress protection for outdoor equipment
Compliance decisions rest with the site owner and the applicable authority. CRATUS designs and documents installations to support your programs and audits; we don’t self-certify.
The basics
What does material tracking cover?
What was mined or delivered, how it was moved, where it is stored, how much is left and where it was used. ASSET-Rx combines LiDAR measurement with tracking of trucks, loaders and delivered material.
How is stockpile volume measured?
LiDAR scans the pile surface and computes volume. Weight is calculated from your material density and checked against scales and surveys.
Does it replace surveys?
It reduces how often you need them. Surveys remain the reference for audits; LiDAR keeps inventory current between them.
Mining and quarries
Can it measure truck loads?
Yes. LiDAR measures the material in truck beds and rail cars as they pass, so each load has a measured volume instead of a nominal payload.
How does it handle dust?
Sensors are placed and protected for dusty sites, with enclosures and air purge where needed, and filtering removes airborne dust from the measurement.
Does it work with our fleet management system?
Yes. Fleet and equipment data can be brought in through APIs and combined with LiDAR measurements and tag data.
Construction
How is delivered material tracked on a project?
Deliveries are tagged at the gate and linked to the order. Tags locate the material in laydown or on the floor until it is installed.
Can it support job cost?
Yes. Delivered, stored and installed quantities are reported by area and cost code, so job cost uses measured quantities.
