“…In this sense, building failure refers to the aging of the buildings (Mac- Barango and Kakulu, 2011). This is seconded by Jamaluddin et al (2017), whereby physical and structural deteriorations are two variables that contribute to building failure. While the building age can be a factor in determining maintenance costs, it will also depend on the standard of maintenance that the building has received over the years (Mac-Barango and Kakulu, 2011).…”

“…While the building age can be a factor in determining maintenance costs, it will also depend on the standard of maintenance that the building has received over the years (Mac-Barango and Kakulu, 2011). A structure's strength and stability are substantially decreased when anything goes wrong with the design (Al-khatam, 2003;Chew et al, 2004;Cunningham, 2013;Jamaluddin et al, 2017). Building structure is concerned with the size, shape and complexity of the building.…”

Purpose To achieve efficient operation and maintenance (O&M) management, this study seeks to identify critical success factors (CSFs) affecting service delivery factors of O&M services at stratified residential buildings. The purpose of this study is to yield measurable data for developing an effective O&M framework to enhancing its performance. In future research, this study will further investigate the relationship between the CSF and service performance factors. Design/methodology/approach This study adopts a combination of qualitative and quantitative techniques that yields conclusive study findings while improving the research’s validity and dependability. Two series of instruments were conducted in an effort to refine the efficient O&M framework variables. Instruments used in addressing the research gap were a questionnaire survey and focus group discussion (FGD). Analysis of data was completed via the Statistical Package for the Social Sciences (SPSS) programme for quantitative data and thematic analysis for qualitative data. Findings This study concludes that the CSFs directly affect the performance of O&M. Questionnaire survey and FGD findings have refined the CSF into three main categories, namely, building characteristics, O&M management and community participation. FGD experts further suggested that service performance factors can be measured against SERVQUAL service qualities such as reliability, tangible, responsiveness, assurance and empathy. Research limitations/implications Future research may consider the inclusion of financial elements in the O&M service delivery. Originality/value This study presents a fresh insight into the CSFs that construct an efficient O&M framework through rigorous steps of data collection and analysis. This study proposes impactful guidance for policymakers, practitioners and residents on the significance of all parties’ involvement to support the management of residential buildings, where the current practice of O&M constantly faces complex issues. This study derives novice strategies that should correspond to the growing issues and challenges in managing residential buildings. The deeper insight into the role of O&M represents a direction for the future development of facilities management progress and stratified residential building sectors.

“…Cracks are one of the critical structural defects to determine an early possible structural failure in a building integrity inspection [17]. Building surveyors conduct structural inspection by collecting visual data to identify various defects due to environmental exposure during the service life of the structure (such as cracks, loss of material, rusting of metal bindings, etc).…”

Cracks are one of the critical structural defects in building assessment to determine the integrity of civil structure. Structural surveying process using computer vision is required to automatically identify cracks. The application of Convolutional Neural Networks (CNNs) is limited by its fixed geometric kernels to extract the irregular shape of cracks. In this paper, a mask Region-based Denoised Deformable Convolutional Network (R-DDCN) is proposed to detect cracks for accurate instance segmentation and image classification. Denoised deformable convolution is introduced to improve the modeling capability of convolution layer. It adopts the existing deformable convolution, with non-local means as a denoising mechanism to optimize the augmentation of spatial sampling locations with filtered offsets. Experimental results show that the proposed mask R-DDCN has lower validation loss and improved mean accuracy precision of mAP75 from 66.7% to 76.7% as compared to the mask R-CNN. Mask R-DDCN can perform better modeling capability in cracks identification.
