“…In addition, the construction method and engineering of these buildings cause them to be prone to structural failures and cosmetic defects. However, the massive costs to restore and conserve such types of buildings are quite high and rely heavily on accurate dilapidation survey and analysis (Smith & Quintero, 2018). Hence, this paper aims to utilize LiDAR to study a sloping floor as part of dilapidation survey of heritage building.…”

Heritage building restoration and preservation work relies heavily on a thorough inspection of building condition survey. One of the building dilapidations that may occur in a heritage building, is sloping floor defect where the floor is uneven, or slanting towards a specific direction. In this case study, a sloping floor defect was identified at Ipoh Town Hall, Perak which require further investigation. Using conventional methods to survey the sloping floor in building surveying will require more time and manpower. Instead, this paper explores LiDAR scanning methods to measure and identify sloping floor defects. R programming techniques are applied to analyse the point cloud results from the LiDAR survey to assess the sloping floor defect in greater detail.

Metric Rectification of Spherical Images

This paper describes a method for metric recording based on spherical images, which are rectified to document planar surfaces. The proposed method is a multistep workflow in which multiple rectilinear images are (i) extracted from a single spherical projection and (ii) used to recover metric properties. The workflow is suitable for documenting buildings with small and narrow rooms, i.e., documentation projects where the acquisition of 360 images is faster than the traditional acquisition of several photographs. Two different rectification procedures were integrated into the current implementation: (i) an analytical method based on control points and (ii) a geometric procedure based on two sets of parallel lines. Constraints based on line parallelism can be coupled with the focal length of the rectified image to estimate the rectifying transformation. The calculation of the focal length does not require specific calibrations projects. It can be derived from the spherical image used during the documentation project, obtaining a rectified image with just an overall scale ambiguity. Examples and accuracy evaluation are illustrated and discussed to show the pros and cons of the proposed method.

“…Earlier research works mostly focused on early design stages of buildings rather than the maintenance and conservation phases. Previous research mainly dealt with regeneration of building envelope (Khorassani et al, 2018), technological developments (Aghili et al, 2019), digital applications (McGibbon et al, 2018;Smith and Quintero, 2018), life cycle performance criteria (Liu and Qian, 2019), Life-Cycle Costing (LCC) (Zheng et al, 2019) and heritage and environment reconceptualisation (Richards et al, 2019). It raised questions over the lack of investigation into sustainable maintenance management through low carbon repair options in heritage building repair.…”

PurposeLow carbon repair epitomises sustainable maintenance management for heritage buildings. However, there is little recognition of this aspect, coupled with impractical assessment of repair impact strategies. This paper aims to present a decision-making process based on life cycle assessment (LCA) approach of lime plaster repair options for heritage buildings.Design/methodology/approachCalculation procedures of LCA were carried out to enable sustainable maintenance management appraisal for heritage buildings upon embodied carbon expenditure expended from lime plaster repair during the maintenance phase.FindingsCalculation procedures could be understood as a carbon LCA of lime plaster repair and recognised in reducing CO2 emissions. This underpins low carbon of lime plaster repair in achieving sustainable maintenance management of heritage buildings.Practical implicationsIt must be emphasised that the LCA approach is not limited to heritage buildings and can be applied to any repair types, materials used and building forms. This supports environmentally focused economies and promotes sustainable maintenance management solutions.Social implicationsThe LCA approach highlights the efficiency of repair impact strategies through evaluation of low carbon repairs options.Originality/valueThe LCA approach results show that low carbon repair, contextualised within maintenance management, relays the “true” embodied carbon expenditure and stimulates sustainable development of heritage buildings.
