Automated Progress Controlling and Monitoring Using Daily Site Images and Building Information Modelling

Abstract

This research presents a novel method for automated construction progress monitoring. Using the proposed method, an accurate and complete 3D point cloud is generated for automatic outdoor and indoor progress monitoring throughout the project duration. In this method, Structured-from-Motion (SFM) and Multi-View-Stereo (MVS) algorithms coupled with photogrammetric principles for the coded targets’ detection are exploited to generate as-built 3D point clouds. The coded targets are utilized to automatically resolve the scale and increase the accuracy of the point cloud generated using SFM and MVS methods. Having generated the point cloud, the CAD model is generated from the as-built point cloud and compared with the as-planned model. Finally, the quantity of the performed work is determined in two real case study projects. The proposed method is compared to the Structured-from-Motion (SFM)/Clustering Multi-Views Stereo (CMVS)/Patch-based Multi-View Stereo (PMVS) algorithm, as a common method for generating 3D point cloud models. The proposed photogrammetric Multi-View Stereo method reveals an accuracy of around 99 percent and the generated noises are less compared to the SFM/CMVS/PMVS algorithm. It is observed that the proposed method has extensively improved the accuracy of generated points cloud compared to the SFM/CMVS/PMVS algorithm. It is believed that the proposed method may present a novel and robust tool for automated progress monitoring in construction projects.

A Real-Time Physical Progress Measurement Method for Schedule Performance Control Using Vision, an AR Marker and Machine Learning in a Ship Block Assembly Process

“…Recently, imaging systems have been used as work performance measurement methods in various industries in order to reduce time and manpower required for performance data collection [ 25 , 27 , 28 ]. The method of measuring process progress using the imaging system is to measure progress by comparing as-planned models and real time as-built images collected at the site.…”

“…Behnam, A. et al [ 24 ] made an online progress reporting and automated progress measurement system for repetitive construction tasks using satellite remote sensing technology in linear infrastructure projects. Mahami, H. et al [ 25 ] presented an automated construction progress monitoring method using site image and building information modeling. The quantity of the work performed is determined by creating an as-built 3D point cloud of the measured target and comparing it with the as-planned model.…”

Remote Indoor Construction Progress Monitoring Using Extended Reality

“…One of the primary aims of inspection is to evaluate dimensional (dimension and position) errors and surface defects (cracks and spalling) in activities involving concrete columns and HVAC pipes [8]. However, conventional methods for construction work inspection are time-consuming, needs inspection manpower [9], consume energy, economically, inefficient and prone to errors [10]. Therefore a more sustainable and automated construction progress monitoring needs to be developed to operate at a lower cost, less manpower, and a healthier construction environment by reducing the physical interaction between construction worker and inspector.…”

“…Considerable amounts of these buildings are small construction projects. Inspection and continue monitoring of this considerable number of projects consume a lot of manpower, time, data management, and travel between sites which will cause pollution, energy and economic loss, and higher risk [1,9]. Therefore, remote monitoring of multiple activities at the same time using extended reality technologies might reduce the number of inspectors needed [11].…”

Digital Modelling and Accuracy Verification of a Complex Architectural Object Based on Photogrammetric Reconstruction

“…The resulting 3D models can also be used in heritage building information modelling (HBIM) applications [23][24][25][26] and to evaluate distinctive properties of existing buildings [27]. SFM and MVS reconstructions made using VisualSFM software can monitor construction progress via comparison with BIM models [28]. The model can be presented as a video game environment [29], a virtual reality element, or be recreated in 3D printing as a mock-up, which guarantees the accessibility of knowledge for blind and visually impaired people [30].…”
