A scan to as-built building information modeling workflow: a case study in Malaysia

Abstract

Purpose Three dimensional (3 D) laser scanner surveying is widely used in many fields, such as agriculture, mining and heritage documentation and can be of great benefit for as-built documentation in construction and facility management domains. However, there is lack of applied research and use cases integrating 3 D laser scanner surveying with building information modeling (BIM) for existing facilities in Malaysia. This study aims to develop a scan to as-built BIM workflow to use 3 D laser scanner surveying and create as-built building information models of an existing complex facility in Malaysia. Design/methodology/approach A case study approach was followed to develop a scan to as-built BIM workflow through four main steps: 3 D laser scanning, data preprocessing, data registration and building information modeling. Findings This case study proposes a comprehensive scan to as-built BIM workflow which illustrates all the required steps to create a precise 3 D as-built building information model from scans. This workflow was successfully implemented to the Eco-Home facility at the Universiti Teknologi Malaysia. Originality/value Scan to as-built BIM is a digital alternative to manual and tedious process of documentation of as-built condition of a facility and provides a detail process using laser scans to create as-built building information models of facilities.

Digital-Twin-Based Evaluation of Nearly Zero-Energy Building for Existing Buildings Based on Scan-to-BIM

“…e method of converting 3D scanning point cloud data of existing buildings into BIM model is known as scan-to-BIM [29]. From the perspective of academic value, the application of point cloud technology in the construction industry is still at the initial stage, and there is still no unified standard or application mode.…”

“…e processing of point cloud data required to scan a target building with a 3D laser scanner has been discussed in detail in previous studies [26,29,30]. e application process of 3D laser scanning technology is shown in Figure 1.…”

Building Information Modelling (BIM) and the Internet-of-Things (IoT): A Systematic Mapping Study

“…In this systematic mapping study, we observed that 32 studies out of 55 were not empirically validated [8]- [11], [20], [23]- [29], [44]- [48], [56], [60][29], [30], [54], [55], [61], [34], [36]- [38], [40], [42], [43], [53], which amount to 58.18% of the selected studies. We come to this conclusion by taking two things into consideration, which are the performance measure and simulation tool of a given study.…”

Measuring Sloping Floor of Heritage Building Using Point Cloud Data from LiDAR Survey

“…The first form of LiDAR technology was introduced in 1961 which was initially intended for satellite tracking. By calculating the return time of emitted lasers, by using sensors and data acquisition electronics, the distance of two points can be measured (Rahman et al, 2019). Today, LiDAR technology has improved significantly, by utilizing a LiDAR scanner unit that can rotate on an axis on a tripod, known as TLS (Terrestrial Laser Scanner) unit.…”
