Abstract
Abstract. The construction industry is still one of the least digitised sectors worldwide and digitisation in the road construction sector in particular is even more dire. To improve the efficiency of the sector, it is of the utmost importance that construction monitoring tasks, i.e. progress, quality and quantity analyses, are automated. The goal of the presented framework is the automation of the following three vital interconnected subjects: (1) The systematic capture of remote sensing data with low-cost UAVs, (2) the information extraction from survey data and (3) the interlinking and exchange of interoperable BIM data (design, survey and extracted information) using Linked Data technologies. In this paper, the needed data for proper road construction digitisation and the desired data structure is discussed. Additionally, the automation of Real Time Kinematic (RTK)-flight processing is presented. The feasibility of the proposed workflow is examined based on real-life test cases. As a consequence of automation, the homogeneity of data across projects will increase. This will form the basis for further automation in road construction.
Highlights
The construction industry and in particular the road construction industry, has had very limited digitization (Agarwal et al, 2018)
A recent study in Belgium shows that Building Information Modelling (BIM) is increasingly adopted in the construction sector
Flemish road designers and contractors are required to deliver BIM datasets to Agentschap Wegen & Verkeer (AWV) according to the concepts in the AWV-Object Types Library (OTL)
Summary
The construction industry and in particular the road construction industry, has had very limited digitization (Agarwal et al, 2018). The failure costs combined with the ambition of AWV to apply BIM during the entire lifecycle of the road infrastructure, from design to management, requires a thorough and concise implementation in conventional road construction workflows. In addition to applying BIM, AWV has introduced Linked Data principles i.e. AWV Object Types Library (OTL) to improve data management. Flemish road designers and contractors are required to deliver BIM datasets to AWV according to the concepts in the AWV-OTL. Using this BIM with the corresponding AWV-OTL is part of the research. There are several types of BIM throughout the life cycle of a road construction These different BIM models will be adjusted and compared based on accurate measurements
