Maintenance Schedules, As-Built Handover and After-Sales Support
Operational maintenance manuals, MEP equipment warranties, facade joint inspections, and distinguishing building envelope warranties from third-party fixture guarantees. How to ensure decades of trouble-free performance.
1. The As-Built Handover Dossier & Digital BIM Twin
At project completion, SERMODULA delivers a comprehensive As-Built Handover Package. Because modular buildings are manufactured in a digital BIM environment, every pipe run, electrical junction box, structural anchor point, and concealed wall framing stud is mapped to millimetric accuracy.
Homeowners and facility managers receive manufacturer test certificates, HVAC commissioning logs, electrical compliance sign-offs, and clear access maps for cleanouts and filtration cartridges, eliminating the guesswork typical in traditional brick-and-mortar homes.
2. Scheduled Periodic Maintenance Milestones
During the first 6 to 12 months, building finishes accommodate natural foundation settling and seasonal humidity changes. While precision-welded steel frames do not warp or shrink like raw timber, elastomeric silicone joints around exterior panel transitions and roof parapets should be visually inspected annually.
Mechanical ventilation (MVHR) filters must be cleaned or replaced every 6 months to maintain optimal indoor air quality and energy recovery efficiency. External rainscreen facades and drainage gutters require inspection every 24 months to clear debris.
3. Understanding Warranty Boundaries & Service Protocols
SERMODULA provides a 10 to 50-year structural design life warranty on the hot-rolled and cold-formed steel chassis and primary framing against corrosion and structural failure, in accordance with applicable Eurocodes.
In contrast, active mechanical equipment (heat pumps, inverters, kitchen induction cooktops, sanitary valves) carry standard warranty terms provided directly by the component manufacturers (e.g., Daikin, Mitsubishi, Grohe). SERMODULA provides after-sales technical escalation to assist clients in resolving equipment service requests smoothly.
