Technical maintenance contracts for buildings

A technical maintenance contract turns a collection of one-off inspections into a service with clear rules. It is designed for property managers, building managers and facilities managers who need to know what is covered, how faults are handled and what information they will receive throughout the year. At MRS Climatización we put in place annual maintenance contracts for HVAC, electrical installations, industrial refrigeration, and water and gas installations in commercial and institutional buildings.

What a maintenance contract sets out

A good contract removes ambiguity. These are the points worth putting in writing:

• An inventory of the equipment and installations covered, with their locations.
• Preventive tasks for each type of equipment and how often they are carried out.
• Priority criteria for faults and corrective work.
• Which work is included and which is quoted separately (materials, spare parts, work at height, replacements).
• The format and frequency of technical reports.
• Named contacts on both sides and the channel for reporting faults.
• Access arrangements, working hours and coordination with other contractors.

The more detail agreed at this stage, the fewer disputes later. An inventory that records the exact location of each unit, for instance, removes any doubt about whether a particular unit is covered when a fault appears, and lets any technician find it on their first visit.

Priorities based on criticality

Not every fault has the same impact. A chiller serving an entire building, a cold room or a main distribution board cannot be treated in the same way as an indoor unit in a single office. The contract classifies equipment by criticality and sets out how calls are prioritised. In practice, three levels are usually enough: equipment whose failure stops operations or affects people, equipment with a significant impact on comfort, and equipment whose fault can wait for a scheduled visit. Service conditions are defined in each contract rather than in general terms, because they depend on the building, its use and the type of installation.

One point of contact for several installations

When HVAC, electrical and refrigeration systems are handled by different companies, every fault that crosses disciplines means coordinating several contractors, and accountability becomes blurred. Bringing these installations under one contract simplifies management and makes it clear who is responsible. We explore this further in the article one supplier, clearer accountability.

Monitoring and periodic reports

The value of a contract lies not only in the inspection but in the information it produces. Periodic technical reports summarise the condition of the installations, faults attended, outstanding issues and recommendations for improvement or replacement. For the building manager, this is the basis for planning budgets and justifying decisions to the owner. We are also introducing a web platform in which each unit, identified by its label, has a digital record with its service history, upcoming inspections and preventive alerts.

How the proposal is prepared

The process follows four steps: diagnosis, technical proposal, execution and ongoing maintenance. During diagnosis we visit the building, compile or review the inventory and identify critical equipment. From that, we draft a proposal covering scope, schedules and terms. In buildings with particular needs, such as healthcare and care facilities, the proposal takes account of areas where an interruption directly affects people.

How to compare contracts

If you are assessing several offers, compare them against the same inventory and the same tasks. Two figures can look very different simply because one includes corrective work and materials and the other does not. Also check the report format, how interventions are recorded, what happens with out-of-scope work and how the inventory is updated when equipment changes. A more detailed offer is usually easier to monitor during the year as well.
