We define standards

Our IT solutions set standards and contribute to the digitalization of national and international infrastructure. The software is designed for the market-leading database management systems. On this basis, above-ground and underground networks and objects are managed together in one application.
What is BaSYS?
Bundle resources, increase efficiency and thus minimize costs? With BaSYS, the integrative and scalable infrastructure management system, you create the basis for managing your supply and disposal networks, including all facilities, together in one application. The basis is a holistic database structure. As an extended asset management solution, the system accompanies the entire workflow of network and object management and supports you in all the tasks involved:
Planning and acquisition
Graphically interactive planning and acquisition through intelligent integration with leading GIS, CAD and DBM systems. Integrated subject-specific functions such as network planning in parallel in plan, longitudinal section as well as planning of catchment areas for any hydraulic approaches, network tracking, auto-access to survey points and DTM, accurate model-based theme plans and intuitive methods for object layout design.
Cadastre and continuation
Comprehensive functions for practice-oriented collection, processing, continuation and analysis of inventory data as well as maintenance of the rehabilitation inventory. Directive-compliant documentation of indirect dischargers, creation of overview and inventory plans.
Condition and evaluation
Inspection, import and evaluation of inspection results, e.g. from TV inspections (wastewater), pigging sensors (supply) or stereo image inspection (road). Automated condition assessment and creation of damage and condition assessment plans. History management and parallel management of data from different coding systems.
Rehabilitation and repair
Configurable logic for automated planning of different variants (repair, renovation, renewal) based on the relevant inspection. Automatic cost determination via cost estimation (renewal) and a freely definable library of available measures. Preferred variant via object-specific profitability comparison (cost comparison calculation) and strategic asset management. Standardized graphics, reports and topic plans.
Drainage planning
Hydraulic calculation of supply networks (STANET/EPANET) as well as dimensioning and hydrodynamic simulation (MIKE1D) for sewer networks access the inventory database directly without a replacement system. Use for master plan (also withdrawal of extinguishing water) with manifold actual and planning states as well as for general drainage planning of urban and rural sewer networks.
Asset management
Legally compliant asset valuation according to cameralistics and double-entry accounting, basis for fee calculation. Detailed cost calculation. Connection between technical data and asset accounting (SAP, DATEV or MS Dynamics). Cost determination according to quantity and index methods via construction lot management.
Operations management and maintenance
Management and documentation of the assets to be maintained including the associated tasks with integrated maintenance and work planning supported by libraries for the maintenance processes. Consideration of regular and demand-oriented measures as well as route and resource planning. Order-related evaluation and documentation of the work performed.
Information
Comprehensive, web-based information solution for desktop, tablet and smartphone. BaSYS Web Services provide network information directly from BaSYS databases via WebMap servers. Mobile network information and acquisition with GPS and RFID object recognition.
That makes BaSYS unique:
Data structure
Centralized database for all traysData integrity and security
Cross-divisional object information is held centrally in a standardized and non-proprietary encrypted data structure. This includes all important basic data for external (e.g. hydraulic) programs, graphical representation, text releases and customer-specific extensions and specialist shells.
Interfaces
100% ISYBAUThe original
In cooperation with the “Wastewater Working Group” of the German state building authorities, we develop and implement the current “original” ISYBAU interfaces for the data transfer of sewer specialist data. With ISYBAU, DWA M-150, Shape and CAD as well as the universal ASCII interface, we offer a wide range for the import and export of specialist data.
Multi-platform concept
Diversity in front- and backendGreatest possible freedom
The BARTHAUER multi-platform concept offers a uniform user interface for the interlinking of BaSYS in the front end with GIS/CAD systems from the world’s leading manufacturers Autodesk, Bentley, Bricsys, ESRI, Hexagon, and QGIS. In the backend, the three DBMS Microsoft SQL Server, PostgreSQL and Oracle are supported for centralized spatial data management.
Desktop, Web, App
Many platforms - one systemConsistency
Our development philosophy and software architecture offer perfect system consistency – from the desktop solution to the web and apps. A centrally defined model (graphical design), as standard – or individual masks: BaSYS offers a uniform user experience.
SaaS
Rent - Lease - PurchaseFlexible software models
In addition to the classic purchase of our software, we also offer lease financing. You have a large project and need another BaSYS license temporarily? Rent your BaSYS workstation! For the tasks of operations management and information, you can do without software installations on your premises. Use our cloud services in the data center in Frankfurt. We take care of the hardware and software and you have worry-free access as SaaS.
Individuality
Configurable systemConsulting
Together with you, we develop a concept to adapt our products to your individual requirements for efficient use – whether special workflows, unique interface design, special compartment shells or special interfaces to third-party products.
Compliant with regulations
Diverse requirementsIs that right?
BaSYS meets the requirements of the various regulations as well as technical and regional boundary conditions and requirements. Different sets of regulations can be taken into account within a project – in the area of sewer condition, for example, you can manage damage codes in accordance with DWA M-143-2 together with DIN EN 13508-2.
Confidence
Federal Ministry and building authorities rely on BaSYSHighest confidence
Several federal ministeries and building authorities in the 16 federal states of the Federal Republic of Germany have been using BaSYS to manage their many properties since 1991. A sign that the BARTHAUER team with its competence and its products enjoys trust from the highest authorities!BaSYS Modules
