VISUALIZATION OF CONSTRUCTION PROGRESS AND INFORMATION SYSTEM CONCEPT USING THREE-DIMENSIONAL POINT CLOUD DATA

Abstract

The Ministry of Land, Infrastructure, Transport and Tourism (MLIT) aims to introduce ICT for construction sites and utilize three-dimensional data. The MLIT releases data acquired at the stage of planning, investigation, design, construction, and maintenance of civil infrastructures in MLIT Data Platform. However, it is difficult to use a uniform method for data acquisition, because the scale and conditions of construction sites vary widely. And, there are no established method for transferring three-dimensional data among the various project phases of civil infrastructures and for its specific utilization method. In this study, the concept of collecting, processing, managing, and utilizing construction and maintenance management information was proposed based on the definition of information system for constructing and using threedimensional data at small and medium construction site. We verified its application to progress management at the construction site.
