Development of civil works planning and management support system based on 3-dimensional geospatial information model
- 3-dimensional scanning and drones, representative elementary technologies of the Fourth Industrial Revolution, were used to develop a world map platform able to model changes in geospatial information at the construction sites of large-scale civil works; the developed system uses this platform to perform construction planning and management.
ㅇ Research Contents
- Thousands to hundreds of millions of 3-dimensional point cloud data acquired from sites using drones, terrestrial laser scanners (TLS), and mobile mapping systems (MMS) were combined using a World Geodetic System (GRS80) to produce a World Map with improved precision. A data processing and storage function for uploading and managing civil works-related data to a cloud server in real time has been developed.
- Also, a GPS-based site management mobile application (APP) was developed for the checking and management of construction site soil characteristics and risk factors, etc.
ㅇ Research Achievements
- Developed technologies featured in 1 overseas journal article, 1 domestic journal article, 1 overseas academic presentation, and 1 domestic academic presentation on Fourth Industrial Revolution construction technologies (relating to drones and automation)
- Use of smart technologies and development of system functions to shorten existing work processes; expected 20% increase in production and 50% cost reduction in the construction and project management stages
Newly developed technologies
- 3D terrain modeling + reflection of soil characteristics
- Construction planning support through the 3D analysis of cell generation and the management of data related to factors influencing civil works
- Data, including information on soil characteristics, can be exported and shared in various formats
- 3D terrain modeling
- Lack of construction planning support
- Does not reflect soil characteristics/data
Advantages and disadvantages
- Comparisons of planning drawings and current ground status at each construction phase to perform earth-volume calculations and process analyses
- Provides soil characteristics data and information on work-influencing factors when establishing civil works plans, improving planning accuracy
- Earth-volume calculations provided by simply comparing planning drawings with the current ground state
- Approximately 50% cost savings compared to conventional earth-volume calculations using total station surveying
- 25% improvement in civil works precision; 20% improvement in productivity
- Conventional total station (TS) surveying is time-consuming and provides low earth-volume calculation precision
ㅇ Expected Effects
- In 2018, the government announced its Sixth Master Plan for Construction Industry Development, along with its Smart Construction Roadmap. The smart construction and construction drone markets are expected to grow by an average of 12% per year, and it is expected that the technology developed through this research will be adopted by the industry.
- Smart construction (construction and construction project management) practices are expected to spread into various construction areas, including civil works, road construction, and tunnel construction.
