A two-person survey crew routinely drives around with more value in instrument cases than in the vehicle carrying them. A total station, a pair of GNSS receivers, a digital level, and the controllers and accessories around them concentrate a small firm’s capital into a handful of padded boxes - boxes that move daily between the office, vehicles, job sites, and the calibration lab. This guide covers how surveying and geomatics firms keep that kit controlled: what to register, how to handle calibration, and what replaces the kit-room sign-out sheet.

High value, low volume: surveying's particular problem
Most industries lose equipment through volume - hundreds of small items nobody can watch. Survey firms have the opposite profile, and it creates its own failure modes:
- Identical cases hide different contents. The level’s case looks like the prism set’s case. Crews grab the wrong box at 6am and discover it on site, an hour away.
- Accessories scatter faster than instruments. Tripods, prisms, poles, chargers, and data collectors migrate between vehicles until no kit is complete.
- Theft targets survey gear. Instruments are portable, valuable, and easy to resell, and parked vans are predictable targets. A claim without serial numbers and purchase records is a slow, weak claim.
- Two crews, one receiver. Double-booked kit on a Monday morning costs a crew-day, which in a small firm is real money.
- Calibration is invisible. An instrument outside its service window looks identical to one in date. Only the record knows the difference.
What belongs in the register
- Instruments, per item - total stations, GNSS receivers, levels, controllers: serial, purchase price, photos, and service dates on each record.
- Accessories, as kits - bundle the tripod, prism set, and pole with the instrument they support, label the kit, and count contents at return.
- Supporting site kit - the hand tools and power tools used for setting monuments and clearing lines, plus ladders and access kit, tracked to a person or vehicle.
- Safety kit, per person - high-visibility gear, and respirators where contaminated or confined sites demand them, with issue dates recorded.
- Vehicles - with insurance and inspection documents attached to the record.
| Class | Assigned to | Dates on the record |
|---|---|---|
| Total stations, levels | Crew or job, per checkout | Service and calibration |
| GNSS receivers and controllers | Checked out as a kit | Service, firmware notes |
| Tripods, prisms, poles | The kit they belong to | Counted at return |
| Site tools and ladders | Person or vehicle | Periodic inspection |
Calibration, field checks, and the paper trail
Survey instruments carry two layers of checking: the field checks crews run routinely - collimation and two-peg style checks that catch drift early - and the manufacturer service that produces a certificate. Both belong on the record: the next service date as a filterable field, the certificate as an attached document, and the field-check habit written into an inspection schedule rather than a memory. An instrument away for service is checked out to the service centre, so its absence is explained and chased. Deferred services pile into a maintenance backlog that eventually surfaces as crew downtime - the day the only working level is an hour away on another job. A full CMMS is more than a six-person firm needs; an asset register with dates on the records covers the same ground at the right scale.
Tip: label the case and the instrument separately. Cases get swapped, and the label that matters is on the thing that gets calibrated.
Retiring the sign-out sheet
The kit-room sign-out sheet fails for a predictable reason: it records intentions, not events. It gets filled in at 6am departures, skipped at 7pm returns, and stays silent about condition, accessories, and who actually holds the receiver now. A scan-based checkout replaces it: a QR label on the instrument and its case opens the record in a phone browser - no app to install - and the crew checks the kit out to themselves for the job, then back in at return with contents counted. Damage gets reported against the instrument from site, with photos. The Monday morning question - which crew has which receiver - becomes a glance at the register instead of three phone calls.
A register in a day
With a few dozen items, this is a day’s work, not a project:
- List the instruments first. Serials, purchase records, photos - the insurance-grade core.
- Build the kits. Decide what travels together and label each kit as a unit.
- Label everything, instrument and case both.
- Enter service dates with certificates attached.
- Check kit out to wherever it is today - true from day one, even if today’s truth is “both receivers are on the bypass job”.
A register like AMPthilly covers a survey firm’s whole loop: per-instrument records with custom fields, attached certificates and purchase documents, kit checkouts to crews with due dates, an overdue list, QR labels scanned with a phone camera in the browser, a service desk for faults, and a permanent audit history per instrument. The free plan handles 3 users and 25 assets with no card required - roughly the instrument fleet of a small firm - and details are on the pricing page.
FAQ
How do surveying firms keep track of instruments? Serials and QR labels on every instrument and case, kit checked out to a crew or job, calibration dates on the records, and an overdue list someone actually reads.
Should tripods, prisms, and poles be tracked individually? As kits bundled with their instrument, counted at return. Per-prism labelling is effort nobody sustains.
How do you track calibration for total stations and levels? Field checks on a routine schedule, lab service with the certificate attached to the record, and the next due date as a filter.
What is the alternative to a paper sign-out sheet? A QR scan that opens the record in a phone browser - the scan itself is the checkout, so the record matches reality.
How do you handle theft from vehicles? A register with serials, photos, and purchase records turns a theft into a same-day police report and a complete insurance claim.
The takeaway
A survey firm’s exposure is concentrated, which makes the fix mercifully small: serials and photos on file, kits that travel as units, calibration dates on the records, and a scan in place of the sign-out sheet. A day of setup buys insurance-grade records, calmer Monday mornings, and instruments that are where the register says they are.
