A piece of construction machinery has a triple nature: it's an asset (something that can be stolen or broken), a working tool (something that works on the project), and a vehicle (something that, in some cases, travels on public roads). The three natures call for three insurance genres – and disputes around machinery losses almost always come down to the fact that none of the three was ever properly set up.
Standalone plant insurance protects the machine itself: breakdown (internal failure, operator error), natural-catastrophe losses, theft – typically wherever the machine is working or standing. For companies where the machinery fleet is a permanent production asset, this is the continuous solution: it doesn't depend on which project the machine happens to be on. The expectations around theft (site storage, GPS, key control) apply here too: the theft article.
Construction machinery can be added to the project CAR by endorsement – this solution applies for the project's duration and location. Its advantage is simplicity (one policy); its limitation is scope: before and after the project, or on a different site, the machine is uninsured. The detailed boundary: machinery and equipment in the CAR; for a rented machine, the rental agreement is the extra layer: rented equipment.
If the machine is subject to official registration and requires number plates (that is, it has been put into traffic), the operator is liable for compulsory motor third-party liability insurance – regardless of whether the machine actually goes out on public roads; the classification (slow-moving vehicle, self-propelled machine, agricultural tractor) is decided under whatever legislation is in force at the time. Own-damage (casco) cover is also worth considering for the machine's value. Classifying slow-moving vehicles, agricultural tractors and unregistered machines raises detail questions of its own – that's already the territory of the sister site flotta.biz, home to the world of vehicle fleets.
In practice, the question is decided machine by machine: a permanent, high-value fleet deserves standalone machinery insurance; an occasional, project-specific item calls for a CAR endorsement; machines that also travel on public roads need vehicle cover. Making a list is the key: machine type, value, owned/rented, road use – this is the machinery section of the project data sheet. And the portfolio-level overview is the subject of the portfolio article: machinery, fleet, property, liability in one system.

As an independent broker, insurers compete for you – not the other way round. I don't charge a fee for advice – the insurer pays the intermediary's remuneration; it is part of the insurance premium.
