A general contractor’s equipment passes through more hands than anyone else’s on the project. Your own crews use it, the subs borrow it, the site shares it, and at demob everyone assumes someone else loaded it on the truck. The GC owns the gear, carries the replacement cost, and - between concurrent projects, a yard, and a fleet of vans - has the least visibility of anyone on site over where it actually is. This guide covers how general contractors put structure on that: what belongs on the register, how to run sign-outs that crews will actually do, and how to close projects without the scavenger hunt.

The GC's particular problem: everyone borrows from you
Trades firms mostly lose tools to their own vans. A GC loses them outward, in every direction at once:
- Subs borrow by default. The groundworks crew needs the breaker for an hour, the brickies want the mixer, and the site norm is to say yes. Each loan is reasonable; the sum of unrecorded loans is a yard that empties over a season.
- Site equipment belongs to nobody. The compressor that serves three trades is “the site’s” - which means no individual feels responsible for it leaving.
- Concurrent projects share one pool. When two jobs both claim the laser on Monday morning, the loudest foreman wins and the schedule loses.
- Demob is a deadline, not an inventory. The last week of a project is handover, snagging, and the next job’s start date. Equipment recovery runs on whatever someone remembers.
The common fix across all four: every item has exactly one assignment at all times - a person, a crew, a project - and changing it is a recorded act.
What belongs on a GC's register
Register what is expensive, shared, or inspection-dated; leave the rest as crew consumables:
- Air compressors, mixers, breakers, generators - the shared site plant that every trade touches and no one owns.
- Welding equipment - sets, leads, and regulators, with gas handling kit alongside.
- Lifting equipment - slings, shackles, chain blocks, hoists. These carry statutory inspection regimes in most jurisdictions, and an auditor will ask for the records per item.
- Surveying equipment and test instruments - lasers, levels, total stations, meters. Low volume, high value, calibration-dated.
- Power tools above the pain threshold - core drills, big saws, anything whose loss you would feel. Record serials; theft reports and insurance claims need them.
- Temporary site kit - distribution boards, transformers, heaters, drying equipment. Deployed for months, forgotten at demob.
| Equipment class | Assignment model | Date that matters |
|---|---|---|
| Site plant (compressors, mixers) | Assigned to the project | Service interval |
| Lifting gear | Assigned to project or yard | Statutory inspection |
| Lasers, instruments | Bookable pool, checked out per task | Calibration |
| Power tools | Checked out to crew lead | Service / PAT-style checks |
| Temporary power and heating | Assigned to the project | Recovery at demob |
From sign-out sheets to scan-out
Most GCs have tried the paper version: a sign-out sheet on the container door, or hand receipts for big-ticket items. The idea is right - custody acknowledged by a named person - and the failure is always the medium. Sheets get wet, slips get lost, and nobody can total up who currently holds what.
The durable version keeps the idea and changes the mechanics: a QR label on the item, scanned with a phone camera at handover, recording the same who-what-when in seconds. The custody log builds itself as a side effect of the handover, which is the only way site crews will ever maintain one. No clipboard survives a wet October; a thirty-second scan does.
Tip: put the label where gloved hands can reach it but grinders cannot - on the body casting, not the handle, and never on a replaceable part. A label on the cover plate walks away with the cover plate.
Lending gear to subcontractors
Loans to subs deserve more formality than internal moves, because recovery has a hard deadline: the day the sub leaves site, your leverage drops to zero.
- Named borrower, not a company. “Checked out to M. Kowalski (Apex Groundworks)” - a person who can be called, not a firm that can shrug.
- Due date on every loan. Open-ended loans to subs are donations with extra steps.
- Condition noted both ways. What state it left in, what state it returned in. Disputes about a wrecked breaker are settled by the record, not by who shouts better.
- Check the list before final account. A sub’s open checkouts at demob are items to recover before sign-off, while the commercial relationship still has teeth.
Project closeout without the scavenger hunt
Everything deployed for the project’s duration - the compressor, the distribution boards, the drying kit - is assigned to the project itself. Then closeout has a mechanical step: pull up the project’s open assignments, and work the list. Each item returns to the yard, transfers directly to the next job, or gets an explanation in writing. Five years of “we’ll find it later” is how a GC ends up rebuying its own yard; one closeout list per project is how it stops.
A staged rollout that sticks
- Stage one: the yard. List and label what is in the yard and containers today, with serials and photos. This is the baseline.
- Stage two: the expensive and the inspection-dated. Lifting gear, lasers, welding sets - the items where the record has legal or insurance weight.
- Stage three: one live project. Assign its deployed equipment to the project and run the next closeout from the list. One clean demob converts more sceptics than any memo.
- Stage four: the sub-loan rule. No equipment leaves with a sub without a scan. Make it the storeman’s hill to die on.
On tooling: AMPthilly maps directly onto this pattern - assets assigned to people, departments, or locations (run each crew as a department and each project as a location); checkouts with due dates and conditions on return; printable QR labels scanned with any phone camera in the browser, no app to install on a foreman’s phone; and a service desk so a dead compressor gets reported from site with a photo, with the history staying on the machine. The free plan (3 users, 25 assets, no card) covers stage one and two for a small GC; the features page shows what the paid tiers add.
FAQ
How do general contractors keep track of tools across job sites? Unique IDs and labels, one assignment per item (person, crew, or project), every handover recorded by a scan, and a weekly overdue review.
Should a GC track equipment loaned to subcontractors? Yes - named borrower, due date, condition both ways, and the open-checkout list reviewed before the sub’s final account.
What is a hand receipt, and does a digital version work? A signed acknowledgement of custody. The digital checkout keeps the idea and fixes the medium - nothing to lose, and a live list per holder.
How do you recover equipment when a project closes? Assign deployed kit to the project; at closeout, its open-assignment list is the demob checklist - return, transfer, or explain.
Is tool tracking worth it for a small general contractor? Two crews already have the full problem. Track the expensive, shared, and inspection-dated items first; one recovered welding set pays for the effort.
The takeaway
A general contractor’s gear leaks outward - to subs, to sites, to projects that end faster than anyone inventories them. The register holds when every item has one assignment, every handover is a scan, sub-loans carry due dates, and closeout works from the project’s list rather than the foreman’s memory. The trades around you - electrical, plumbing, HVAC - fight the same fight at van scale; the GC fights it at project scale, and wins it the same way.
