Managing equipment, warranties and service operations across the entire lifecycle. Construction and installation projects rarely end when the building is finished. In reality, the most complex phase begins after the installation – when equipment must be maintained, serviced, and monitored for years. Modern buildings and technical installations include hundreds of systems, such as: - HVAC systems - elevators and lifts - heat pumps - ventilation systems - fire protection systems - solar energy installations - building automation devices Each of these assets generates ongoing operational requirements: - service contracts - equipment warranties - periodic maintenance schedules - service requests and repair tickets - complaints and defect reports - operational costs Without the right software, companies often manage this information across spreadsheets, emails and disconnected service tools. AMPER Flow addresses this issue by offering a centralized platform for managing the project service lifecycle, integrating asset tracking, field service management, and maintenance planning into a single system.
