Aligning Maintenance Schedules with Contractor Warranties After Handover

The first months after handover are a critical period for any building. Systems are running under real conditions for the first time, early defects begin to appear, and most installed equipment is still under contractor or manufacturer warranty. How maintenance is organized during this period has a direct effect on both building performance and the owner's ability to use those warranties.

Linking Maintenance Activities to Warranty Terms

Many warranties include conditions. Equipment may need to be serviced at specific intervals, by approved technicians, using specified parts, for the warranty to remain valid. A maintenance schedule that ignores these terms can unintentionally void coverage.

• Building a register of warranties for each system and major item of equipment, with start and end dates.
• Recording the maintenance conditions attached to each warranty.
• Aligning inspection and service dates with those conditions.
• Identifying which tasks are the contractor's responsibility during the warranty or defects liability period and which fall to the owner's maintenance team.

Clarifying Responsibilities to Avoid Gaps

Gaps often arise where responsibilities are unclear. If a fault appears, the operations team needs to know immediately whether to report it to the contractor under warranty or address it in-house. A clear responsibility matrix and agreed reporting procedure reduce delays and disputes.

Regular joint inspections with contractors during the warranty period are also valuable. They help identify defects early, confirm that corrective work is completed and build a record of issues before warranties expire.

Catching Early Defects and Planning Ahead

Early defects, such as leaks, faulty controls or noisy equipment, are easier and cheaper to fix while warranties are active. A well-structured schedule ensures these items are logged, followed up and closed out. As warranty expiry dates approach, the schedule should prompt a final inspection so that outstanding issues are raised in time.

Looking further ahead, the warranty period is also the right time to establish the long-term preventive maintenance program that will take over once contractor obligations end.
