Inhalt:
Bridges are prone to a high level of deterioration because of their frequent and heavy load. To ensure traffic and structural safety as well as durability, bridges are inspected frequently. Often, it is more efficient to demolish and repair a bridge because their maintenance and repair of them are expensive primarily due to high staff efforts. Furthermore, registering condition states, performing assessment, and preparing data for maintenance tasks are time consuming and error prone because of primarily paper-based workflows and manual copy-pasting. An improvement in digitizing bridge condition data would decrease the demand of manual work, helps to lower financial efforts for these tasks; therefore, makes inspection, maintenance, and repair more attractive. In the long term, this results in lower costs, building material demand, and also CO2 emissions. BIM aims to support the entire building life-cycle using geometric-semantic models of the building.
Inhalt:
Currently, acquiring, exchanging, and processing of building data during design, planning, and construction of buildings have been investigated. Studies about the efforts and effects of BIM show a big potential saving time and money as well as reducing construction errors. However, BIM lacks support of the longest phase of a building or structure: the operating phase. Using BIM during the operating phase has gotten less attention and a systematic and comprehensible methodical approach is missing to model data from the operating phase. In particular, this information is relevant for civil engineering structures, for example, bridges, because it helps to ensure traffic and structural safety as well as durability. During frequent inspections, deficiencies and defects are registered on paper and later manually transferred into table-based systems in the office.
Inhalt:
As BIM helped to reduce plans and reports during the design, planning, and construction phase, it is assumed that this reduction can also be achieved during operating phase. In order to use BIM during the operating phase of bridges, two geometric-semantic models need to be developed: one model for bridges themselves and one model of deficiencies and defects affecting these bridges. Numerous bridges are older than the concept of BIM, which means that there are no geometric-semantic models of these bridges. Some concepts, for instance Scan-to-BIM aim to generate geometric semantic models of existing buildings. As for the second requirement, a digital model for defects and deficiencies, a huge gap is evident. In situations where geometric-semantic models of damage and defects exist, they are incomplete and designed for specific applications.
