The availability of a suitable and efficient transport infrastructure is a fundamental prerequisite for the mobility of society and the successful development of the economy. Politicians at the federal, state and local levels have recognized that the focus must be on maintenance rather than new construction, as the ageing substance of road structures, bridges and cycle paths urgently needs to be renewed or protected from further decay. In addition to a suitable strategy, appropriate financial and human resources are required to carry out the technical planning and to tender and implement the construction work. Maintenance management, i.e. surveying and maintaining the inventory and condition data, determining and forecasting the maintenance requirements, developing maintenance programs, planning and implementing maintenance measures and controlling, is performed in a cycle process. HELLER offers practical solutions for all process steps.
Systematic Maintenance Management
HELLER has been offering successful solutions for a systematic maintenance management for more than 25 years. These solutions include established methods for assessing the condition of existing structures, efficient tools for the strategic and operational maintenance planning as well as tried and tested approaches for the development of suitable maintenance strategies and construction programs.

Pavement condition survey and assessment (ZEB)
Not only the federal government, federal states and districts, but also increasingly administrative districts, rely on the procedure of condition survey and assessment (ZEB). Specialist companies use high-speed measuring vehicles to inspect the road network and to record the condition. HELLER supports the road authorities in tendering for these complex services, in scheduling and quality assurance and carries out all necessary evaluations and assessments. With the mobile solutions of HELLER Ingenieurgesellschaft mbH, local side roads and secondary structures can also be surveyed and assessed efficiently. All results of the condition survey and assessment are processed and made available in such a way that they can be used immediately and efficiently for maintenance planning at the strategic and operational levels.
Pavement Management System (PMS)
Pavement management systems are software tools with which the condition development and the implementation of the necessary maintenance measures can be simulated on the basis of models. The tools are primarily used to answer strategic questions, for instance determining the required resources or developing and reviewing maintenance strategies.
The company's own system PMS Core was developed specifically for the German market. It takes into account the current standards of the federal government and states and enables the determination of resource requirements for a targeted quality of service (quality scenario). Moreover, it allows the forecast of condition development depending on the budgets used (budget scenario). The optimization algorithms are accepted by experts, based on established heuristic methods and deliver reliable results. These can be presented in the form of maps, lists and statistics and be displayed in the OnKo3 online information system for further planning.
Determination of the need for maintenance
Many road authorities use a method developed by HELLER to determine the maintenance needs in the course of maintenance planning. The procedure, which can be adapted to the respective local requirements, isolates all sections in need for maintenance from the data of the condition survey and assessment (ZEB) and combines them into so-called maintenance sections. These are presented as lists or visualized on maps for further planning, e.g. the specification of the construction program. The sections can be prioritized on the basis of predefined parameters, such as condition and traffic load. Due to its simplicity and transparency, the method is very popular among the engineers responsible and also among decision-makers in politics.
Prioritization and coordination of maintenance measures
The development of construction programs is a complex activity since optimization criteria, such as the improvement of substance and trafficability or safety, but also restrictions, such as tight budgets, the demands of management or traffic flow, must be taken into account. With the procedures and tools of HELLER Ingenieurgesellschaft mbH, maintenance programs can be set up efficiently and prioritized in a comprehensible manner. The planning tool hiEMS can be used to automatically calculate all necessary key figures, e.g. condition values and traffic volumes, for the selected maintenance sections and, if required, generate profiles with the relevant information and images from the condition survey and assessment. These can also be displayed and used in the OnKo3 online information system.
