A surveying or engineering firm sends small crews to many sites, often remote, with a truck full of instruments worth more than the truck itself. The project manager knows which jobs were scheduled, but not which crew reached which site, when they arrived, how long they stayed or whether the total station came back. GPS tracking from High Point GPS puts every truck and every crew on one live map in the High Point GPS platform. Geofences around each project site produce an arrival and departure record that flows straight into the timesheet and the client invoice. Bluetooth asset tags on GNSS receivers, total stations, scanners and drones show which instrument is in which truck, and raise an alert when a case leaves the vehicle outside a site or the office. The IOX-NFCREADERA driver ID reader attributes each trip to a named employee, which matters when engineers, technicians and summer students share the same vehicles. Field days in areas with no cellular coverage are stored on the GPS tracking device and uploaded when the truck returns to range. Engine-hours maintenance reminders and fault codes keep long-distance trucks off the shoulder, and driver scoring keeps the firm's insurance and its reputation at client sites intact. When a client questions a site visit, the answer is the trip replay and the geofence record, not the crew chief's memory.

## Common problems

- Field hours on a timesheet that cannot be matched to a site, so a client disputes the invoice and the firm has no record to show
- Instruments worth tens of thousands of dollars that travel in the back of a pickup with no record of which truck they are in
- Shared trucks driven by engineers, technicians and students, with no way to know who was behind the wheel on a given trip
- Sites in areas without cellular coverage where the office loses sight of the crew for the whole day
- Mileage claims and project cost allocations built by hand from memory at the end of the month
- Long highway runs on aging trucks where a breakdown strands a crew and a day of scheduled work

## Highlights

- Live map of every survey truck and field crew, with the project sites drawn as geofences beside them
- Arrival and departure records per project site that feed the timesheet and the invoice line without a manual entry
- Bluetooth asset tags on total stations, GNSS receivers, scanners and drone cases, showing which instrument rode in which truck
- Alerts when a tagged instrument leaves a vehicle anywhere other than a project site or the office
- Named driver on every trip through the IOX-NFCREADERA reader, for shared vehicles and pool trucks
- Trips recorded offline on the GPS tracking device in areas without coverage and uploaded when the truck returns to range
- Mileage per project and per client from the trip history, ready for cost allocation and expense reimbursement
- Engine-hours maintenance reminders and fault codes for trucks that spend their week on the highway

## Every site visit becomes a record a client can check

The firm's revenue is field time, and field time is the thing hardest to prove. High Point GPS draws a geofence around each active project site, and the platform writes an arrival and departure record every time a truck enters and leaves it. The crew chief no longer reconstructs the day from memory; the timesheet shows 8:12 to 14:40 at the highway interchange survey, 15:05 to 16:30 at the subdivision, with the driving in between. The project manager pulls the site-visit report by client and by project at month end, and the invoice line carries the same times the client's site superintendent saw the truck arrive.

When the client questions a bill, the dispute takes minutes. The trip replay shows the truck on the access road, stopped at the control point for three hours, and the return trip. If a crew was sent back because the site was not ready, the record shows the short visit and the second trip, and the firm bills both. Firms working under public-sector contracts find the same records satisfy an auditor asking whether the hours on the invoice match the hours on the ground. The same replay is what a project manager shows a client who asks why a survey took longer than quoted.

## Protecting the instruments, not just the truck

A survey truck carries a total station, a GNSS base and rover, a scanner, a drone and the tripods and prisms that go with them. The insurance claim after a theft is painful; the lost field days while replacements arrive are worse. Bluetooth asset tags from High Point GPS go on each instrument case, and the GPS tracking device in the truck reports which tags it can see. The High Point GPS platform shows the total station in truck 14 at the office yard, and it shows the moment the scanner case stopped travelling with the truck. A rule raises an alert when a tag separates from its vehicle anywhere other than a project geofence or the shop.

The same tags answer the Monday-morning question of where the equipment went. A technician swapped the rover into another truck on Friday; the tag history shows which one. An instrument is due for calibration; the report shows which truck has it and where that truck is. For high-value items that travel between trucks and stay on site overnight, a battery-powered tracker reports position on its own, so the firm sees the instrument even when no vehicle is near it. The report also lists tags not seen for a set number of days, which catches a case left at a site before the client does.

## Who drove, where, and on whose project

Engineering firms run pool vehicles. An engineer takes a truck to a site inspection on Tuesday, a technician takes the same truck to a survey on Wednesday and a co-op student takes it to pick up supplies on Thursday. The IOX-NFCREADERA reader on the dash attributes each trip to the person who tapped in, and the High Point GPS platform reports mileage by driver, by vehicle and by the project geofences the trip visited. The finance team allocates vehicle cost to projects from the report rather than from a mileage log that half the staff forgot to fill in.

Driver scoring becomes useful for the same reason. A firm's trucks carry its name to client sites and municipal rights-of-way, and a truck seen speeding through a subdivision under construction reflects on the firm. Speed limits per geofence, hard-braking and cornering events and seatbelt use are reported by named driver, and a supervisor coaches from a specific trip rather than a general reminder. Personal-use rules let staff who take a truck home keep after-hours driving separate from project mileage. The reports go to the safety file that the firm's insurer reviews at renewal.

## Remote sites, long drives and trucks that have to make it back

Survey work goes where the coverage does not. The GPS tracking device keeps recording position, speed and engine data when the truck leaves cellular range, stores the day's trips on the device and uploads them the moment it reconnects. The office sees the crew's last known position during the day and the complete trip history that evening, with the site geofence records intact. Rules such as a check-in expected by a set hour let a manager notice a crew that has not reappeared, which matters for a two-person team working a forestry road.

The trucks themselves take a beating: gravel roads, long highway days and weeks of idling with equipment running off the cab. Maintenance reminders keyed to engine hours and mileage schedule service before a long project rather than during it, and engine fault codes reach the shop when the truck logs them, often before the driver notices anything. High Point GPS sets the reminders to the firm's own intervals and, for trucks that live on rough access roads, installs the rugged GPS tracking device unit built for it. Trip and idling data also show which trucks are underused and could be shared between offices.

## FAQ

### Can survey site-visit records be used for client invoicing?

Yes. Geofences drawn around each project site produce an arrival and departure record for every visit, with times and the vehicle and driver involved. The report is pulled by client or project and matches the invoice line, and the trip replay backs it up if a client asks for detail.

### How does it track instruments like total stations and GNSS receivers?

Bluetooth asset tags attach to each instrument case, and the GPS tracking device in the truck reports which tags it sees. The High Point GPS platform shows which instrument is in which truck and alerts when a tag leaves a vehicle away from a site or the office. Battery-powered trackers cover items left on site.

### Will it work at sites with no cell coverage?

Yes. The GPS tracking device records trips, stops, speed and engine data on its own memory when coverage drops and uploads everything when the truck returns to range. The geofence records for the site are preserved, and the office sees the full day once the truck reconnects. Rules and alerts fire as soon as the data arrives.

### How do we know who was driving a shared truck?

An IOX-NFCREADERA reader on the dash attributes each trip to the employee who tapped their card or fob. Trips, mileage, safety events and site visits are then reported by driver as well as by vehicle, which is how firms with pool trucks allocate cost and coach driving. Personal-use rules keep after-hours trips separate.

### Can vehicle cost be allocated to projects?

Yes. Mileage and time per trip are tied to the project geofences the trip visited, and the High Point GPS platform reports them by project, client, vehicle and driver. Finance pulls the allocation at month end instead of relying on handwritten logs, and the same data supports expense reimbursement. Reports export to accounting through the API.
