Indoor Mobile Mapping Systems and (Bim) Digital Models for Construction Progress Monitoring

Abstract

Abstract. Technological developments of the last decades are making possible to speed up different processes involved in construction projects. It is noticeable what building information modeling (BIM) can offer during the entire lifecycle of a project by integrating graphical and non graphical data, in addition to this, mapping the site with a 3D laser scan has been proved to provide a feasible workflow to compare as built models with as designed BIM, in this way, an automatic construction progress monitoring can also be performed. Terrestrial laser scanners (TLS) are commonly used to map a construction site due the level of accuracy provided, but indoor mobile mapping systems (iMMS) could offer a more efficient approach by speeding up the acquisition time and capturing all the details of the site just by walking through it, provided that the point cloud is accurate enough for the purpose of interest. In this paper, an iMMS is used to track the progress of a construction site, the point clouds were uploaded onto a platform of autonomous construction progress monitoring to verify if the system can meet the requirements of available applications. The results showed that the iMMS used is capable to produce point clouds with a quality such that the construction progress monitoring can be performed.

Smartphone LiDAR Data: A Case Study for Numerisation of Indoor Buildings in Railway Stations

“…In the context of studying other sensors such as the Kinect V2 equipped with a light sensor camera, Lachat et al [ 21 ] highlights the influence of defects such as colour and reflectivity where the Kinect is very often affected by factors such as light and colourimetry on the numerisation of artefact. Sgrenzarol et al [ 22 ] has also shown the use of Mobil scan with Indoor Mobile Mapping Systems (iMMs) for monitoring the progress of buildings during the construction phase. Comparisons have been made between the true depth (Artec Space Spider with Blue Light Technology 1) sensor and the handheld scanner of the iPad Pro.…”

“…TLSs are widely used in a variety of applications, including cultural heritage [3,4], change detection [5,6], monitoring and deformation [7][8][9], as-built modelling [10], and forestry [11]. In the late 2000s, mobile mapping systems (MMS), which operate on a vehicle such as a car, were introduced into mapping operations, mainly for data capture on road infrastructure and building facades [12] and extended its use to various applications [13][14][15][16][17][18][19][20].…”

Feasibility and Accuracy of as-Built Modelling From Slam-Based Point Clouds: Preliminary Results

“…On the other hand, the use of the Building Information Modelling (BIM) paradigm and the demand for as-built BIM models are growing in Architecture, Engineering and Construction (AEC) industry (Banfi, 2017, Banfi, 2019, being critical for a variety of applications, including as-built vs as-designed analyses, change detection and construction progress monitoring (Previtali et al, 2020, Sgrenzaroli et al, 2022. For existing * Corresponding author buildings, BIM modelling turns into a problem of reverse engineering based on 3D point clouds, referred to as the scanto-BIM process (Wang et al, 2019).…”
