What belongs in a maintenance contract, and what gets left out
Most maintenance disputes are not about the work done. They are about what the scope was silent on.
Maintenance contracts are usually compared on price, because price is the only line that is easy to compare. The differences that matter later are elsewhere in the document.
Scope, written as tasks
"Maintain the chiller plant" is not a scope. A usable scope lists the tasks, states the frequency of each, and names the equipment they apply to by asset reference. If a task is not written down, both parties will remember the conversation differently.
What happens when something fails
- Response time, and whether it differs between working hours and the rest of the week
- Whether attendance means diagnosis or repair
- Who carries the cost of parts, and whether there is a threshold above which approval is needed
- What counts as a breakdown rather than a maintenance visit
Exclusions
The most informative section of any maintenance quotation, and the one most often skimmed. Major components, refrigerant, specialist cleaning, access equipment and out-of-hours attendance are commonly excluded. None of those exclusions is unreasonable; being surprised by them mid-year is.
Reporting
What arrives after each visit, in what format, and how soon. Readings recorded over time are what make plant condition visible; a signed attendance sheet is not.
Term and exit
Duration, notice period, and what happens to records at the end. Historical readings belong to the site, not to the outgoing contractor, and saying so in the contract avoids an awkward conversation later.
The practical test
Read the scope and ask: if this went wrong on a Friday afternoon in August, does this document tell me who does what? If it does not, the price comparison is between two different things.
