The amount of deteriorating civil engineering structures and buildings are constantly growing. This ongoing process will make a great impact on resources, environment, human safety and health. Today there is a need of a uniform methodology and systems for maintenance organisation and management.

To manage such issues above two consecutive EU-projects were launched. The EU-project ENV4-CT95-0110 “System and Methods for Assessing Conservation State and Environmental Risks for Outer Wooden Parts of Cultural Buildings” (Wood-Assess) and its successor ENV4-CT98-0796 “System for Maintenance Management of Historic (Wooden) Buildings” (MMWood) achieved all the objectives and resulted in a Maintenance Management System (MMS) version 1.0 software application. The MMS was heavily developed according to the ISO 15686 series “Service life planning” requirements.

A predictive GIS based Maintenance Management System has to correspond to the user needs and co-operate with other systems. It is also of great importance that the system is corresponding to the user-, national- and international standards. To fulfil those requirements the system has to be open and integrative and must cope with adaptations and adjustments of the system.

The MMS software application will be the kernel in the ongoing development of the more comprehensive Life Cycle Management System (LMS). It is therefore important to make sure that the MMS is adaptable to LMS and cope with add-in modules.

By using a slab bridge located in the City of Gävle, Sweden, the adaptation and validation of MMS was executed. The MMS enables systematic structuring of assets and condition assessments of buildings and structures and does also manage to link pictures, drawings, maps, geographic information system (GIS) functionalities and documents. The system administrator does some part of the adaptation and some part has to be adapted by the user himself.

In the near future the MMS will be able to cope with life cycle cost (LCC), life cycle performance (LCP) and life cycle ecology (LCE) add-in applications to achieve full LMS status.
