Price fluctuation is a significant risk factor, in every construction project market. It is unavoidable and difficult to forecast. However, it is often argued that there is a difference between the amount calculated with the CIDA price fluctuation formula method and the actual price fluctuation. Therefore, the aim of this research is to investigate the industry opinion on whether there is a difference between price escalations calculated using the CIDA price fluctuation formula and actual price fluctuation. A qualitative research approach was selected to achieve the aim of this research. Through a broad study of literature, it was identified the most critical factors which affected actual price fluctuation deviation. Meanwhile, semi-structured interviews were carried out to identify the reasons affecting fluctuation difference by analysing the data, which was used, and comparing the opinions given by the interviewees. The data was analysed using context analysis. The results of the research confirm that. there is a difference between the amount of price escalation using the ICTAD price fluctuation formula and the actual being used. The main reason behind this difference is the less accuracy of cost indices. To improve the accuracy of the results of this formula, appropriate data collection using an appreciate sample of contractors in producing price indices is recommended as the main.

Construction materials usually constitute a major portion of the total cost in a building construction project. Despite the potential benefit of ICT, convincing construction organisations to embrace its use and implementation has proved a difficult task. This research seeks to identify the implementation of ICT in construction materials management processes and to investigate on the acceptance of contractors for ICT transformation to the materials management in construction projects. In relation to that, current constraints that are found hindering the acceptance of ICT in materials management processes are also identified. A triangulation research approach which consists of standard derived questionnaires, semi structured interviews with class A contractors and review of previous research were conducted. The findings from this research reveal that the implementation of ICT in the materials management for construction projects in Malaysia is at early stage. Microsoft Excel Spreadsheet and handheld devices are found to be the common ICT tools adopted in the materials management processes. Meanwhile, there is only an average level of acceptance towards the transformation of ICT implementation in the construction materials management. The main barrier is found to be the cost involvement at the initial stage or overall implementation of ICT in the materials management processes. Finally, it can be concluded that there is a lack of awareness towards the ICT implementation of materials management in the construction projects.

Effective project coordination and management of time and cost scheduling in public funded construction projects receive a considerable focus from academics, politicians, and the construction industry itself with opposing points of view. The study objective is therefore to investigate the process of time and cost scheduling during the different project stages, and their relationships between critical factors affecting project schedules. Applied data collection was based on semi-structured interviews and a questionnaire survey with publicly agency employed project managers and property managers. A multiple research approach was thus utilized to mix the two dataset. Findings demonstrate that project complications in the execution stage is associated to lack of project requirements and design with too optimistic project deadline and budget from the initial project stages. Moreover, a relationship was found between the presence of experienced consultants and the achievement of project success throughout the project phases as particular vital.

Purpose This study aims to present the result of an assessment of the risk of construction digitalisation with a view to sensitising and preparing construction organisations for unforeseen issues that might arise in the course of their digital transformation. Design/methodology/approach The study took a post-positivist stance through a quantitative research approach. A survey of construction professionals actively involved in construction projects in South Africa was conducted using a structured questionnaire. The analysis of the data gathered was done using mean item scores, Kruskal–Wallis H test, exploratory factor analysis (EFA) and structural equation modelling (SEM). Findings EFA revealed five principal risk factors (human and financial, technological, legal and security, operations and socioeconomic risk factors) associated with the digitalisation of construction organisations. However, SEM revealed that four out of these risk components have significant direct relationships with some selected digitalisation outcomes. These significant risk factors are technology, legal and security issues, operations and socioeconomic issues. Originality/value This study provides practical insight into the risk inherent in construction digitalisation, and its result can help organisations seeking to be digitally transformed make informed decisions. Theoretically, the study reveals the risks associated with construction digitalisation – an aspect that has not gained significant attention in the current fourth industrial revolution discourse. Therefore, its findings can form a basis for future studies on the risk of digitalising construction organisations.

The construction industry can be identified as one of the main sectors in Sri Lanka where the majority of occupational accidents happen. When considering the Small and Medium Enterprises (SME), occupational accidents have been significantly happened due to many reasons. Among those reasons, negligence of the use of PPE by construction workers has become prominent. Different factors can affect this situation. Among them, individual manifestations such as perceptions, beliefs, experiences and attitudes of the workers can make a significant impact. Hence, there is an emerging need to explore the reasons under these individual manifestations, which encourages the negligence use of PPE. This paper therefore aimed to analyse the individual manifestations to unveil the reasons behind the negligence of use of PPE by construction workers in Sri Lanka. A qualitative research approach was followed to achieve the aim of the study. Case studies were conducted using two SME construction projects. Fourteen semi structured interviews were conducted in both cases with managerial and worker level respondents. Collected data were analysed using code based content analysis. ‘Considering PPE as a disturbance’, ‘lack of experiences of the workers’, ‘poor education level of the workers’, ‘inadequate knowledge and skills of the workers’, ‘poor income level’, ‘age of the workers’, ‘number of dependencies’, ‘poor health condition’ and ‘different lifestyles of the workers’ were revealed through the empirical research findings as the key reasons under individual manifestations, which affect for the neglect usage of PPE by the workers. The knowledge generated through this study can be used in many ways by the industry practitioners to make safe working environment within the construction sites.

Since its introduction, Building Information Modelling has evolved into a major technology in the construction industry, where information flows play a major role. However, the very presence of waste within these flows prevents the technology from reaching its full potential. This paper aims to develop a taxonomy focused on the sources of waste within information flows in BIM projects, as existing taxonomies focus primarily on work and material flows. Using a collaborative design science research approach, the study was divided into two phases: first, semi-structured interviews were used to collect data on BIM practices. The data was then used to identify similarities and contradictions in the information flows using process maps. Second, the ShareLab approach was used to validate the findings through a common agreement. The paper’s main contribution is the taxonomy of sources of waste in BIM project information flows, as it closes knowledge gaps in one of the main flows of construction projects. Another contribution is its use of a new approach to validate an artefact in a Design Science Research methodology named the ShareLab approach.

Purpose This study identifies that bricklaying trade has not benefited much from off-site production, and bricklaying has been highlighted as a trade significantly affected by the documented skills shortage in Scotland with 66% of small and medium enterprises reporting difficulties in recruiting bricklayers. Design/methodology/approach This study used an interpretivistic philosophy adopting the phenomenological qualitative research approach using purposeful sampling technique and semi-structured interviews to allow for emergent themes to develop. The theory of proximal similarity that connects the study’s characteristics and the characteristics of the group under study was adopted. Findings Findings from the emergent themes identified issues grouped into key themes such as inconsistency of income, lack of care and self-employed workforce. The sub-themes included the Scottish climate, risk and profit, physical strain and government expectations and the cost of innovation. These were considered in relation to their existing and future implications for the industry. Research limitations/implications A wider and more diverse group of industry participants from different parts of Scotland would have made the study more representative. Practical implications It is imperative that the Scottish construction industry supports, develops and trains future bricklayers capable of maintaining existing housing stock and to deliver on future construction projects in Scotland. Originality/value This study explores the shortage of skilled bricklayers within the Scottish construction sector.

Background: Physical illness is linked with an increased risk of suicide; however, evidence from China is limited. Aims: To assess the influence of physical illness on risk of suicide among rural residents of China, and to examine the differences in the characteristics of people completing suicide with physical illness from those without physical illness. Method: In all, 200 suicide cases and 200 control subjects, 1:1 pair-matched on sex and age, were included from 25 townships of three randomly selected counties in Shandong Province, China. One informant for each suicide or control subject was interviewed to collect data on the physical health condition and psychological and sociodemographic status. Results: The prevalence of physical illness in suicide cases (63.0%) was significantly higher than that in paired controls (41.0%; χ2 = 19.39, p < .001). Compared with suicide cases without physical illness, people who were physically ill and completed suicide were generally older, less educated, had lower family income, and reported a mental disorder less often. Physical illness denoted a significant risk factor for suicide with an associated odds ratio of 3.23 (95% CI: 1.85–5.62) after adjusted for important covariates. The elevated risk of suicide increased progressively with the number of comorbid illnesses. Cancer, stroke, and a group of illnesses comprising dementia, hemiplegia, and encephalatrophy had a particularly strong effect among the commonly reported diagnoses in this study population. Conclusion: Physical illness is an important risk factor for suicide in rural residents of China. Efforts for suicide prevention are needed and should be integrated with national strategies of health care in rural China.

This paper discusses the challenges of records management that arise from the use of adapted buildings as records centres in Zimbabwe, despite the advantages of using such buildings. A qualitative research approach was used as well as a case study research design. Data were collected from seven officers of the Gweru Records Centre through semi-structured interviews. Personal observation was used to triangulate findings from interviews. It was found that the use of adapted buildings as records centres was a cheaper and quicker way of establishing records centres throughout the country. However, a number of preservation, security and management challenges cropped up as the conditions of the buildings and the environment of the adapted buildings were not conducive to the proper and professional management of records. This study is important in that it explores the prospects and challenges of using adapted buildings as records centres in Zimbabwe, an area that has not been researched by many authors. This provokes archival authorities and the government to seriously consider establishing purpose-built records and archival centres.

Abstract Background Impairment of activities of daily living (ADL) due to hemorrhagic gastroduodenal ulcers (HGU) has rarely been evaluated. We analyzed the risk factors of poor prognosis, including mortality and impairment of ADL, in patients with HGU. Methods In total, 582 patients diagnosed with HGU were retrospectively analyzed. Admission to a care facility or the need for home adaptations during hospitalization were defined as ADL decline. The clinical factors were evaluated: endoscopic features, need for interventional endoscopic procedures, comorbidities, symptoms, and medications. The risk factors of outcomes were examined with multivariate analysis. Results Advanced age (> 75 years) was a significant predictor of poor prognosis, including impairment of ADL. Additional significant risk factors were renal disease (odds ratio [OR] 3.43; 95% confidence interval [CI] 1.44–8.14) for overall mortality, proton pump inhibitor (PPIs) usage prior to hemorrhage (OR 5.80; 95% CI 2.08–16.2), and heart disease (OR 3.05; 95% CI 1.11–8.43) for the impairment of ADL. Analysis of elderly (> 75 years) subjects alone also revealed that use of PPIs prior to hemorrhage was a significant predictor for the impairment of ADL (OR 8.24; 95% CI 2.36–28.7). Conclusion In addition to advanced age, the presence of comorbidities was a risk of poor outcomes in patients with HGU. PPI use prior to hemorrhage was a significant risk factor for the impairment of ADL, both in overall HGU patients and in elderly patients alone. These findings suggest that the current strategy for PPI use needs reconsideration.

BACKGROUND: Neonatal hyperbilirubinemia is a common medical emergency in early neonatal period. Unconjugated bilirubin is neurotoxic and can lead to lifelong neurological sequelae in survivors. OBJECTIVE: To find out the association between serum bilirubin and neurodevelopmental outcome at 1 year of age using Development Assessment Scale for Indian Infants (DASII). METHODS: A prospective cohort study was conducted in the Department of Pediatrics of a tertiary care institution of Central India between January 2018 and August 2019. Total 108 term healthy neonates, with at least one serum bilirubin value of >15 mg/dl, were included. Subjects were divided into three groups based on the serum bilirubin; group 1: (15–20 mg/dl) –85(78.7%) cases, group 2: (20–25 mg/dl) –17(15.7%), and group 3: (>25 mg/dl) –6(5.5%). Developmental assessment was done using DASII at 3, 6, 9, 12 months of age. RESULTS: Out of 108 cases, 101(93.5%) received phototherapy, and 7(6.5%) received double volume exchange transfusion. Severe delay was observed in 5(4.6%) and mild delay in 2(1.9%) cases in the motor domain of DASII at one year. Severe delay in the motor domain was associated with mean TSB of 27.940±2.89 mg/dl and mild delay with mean TSB of 22.75±1.76 mg/dl (p = 0.001). On cluster analysis, delay was observed in locomotion 1 score in 11(13%) cases (p = 0.003) and manipulation score in 6(7.1%) cases in group 1. CONCLUSION: Increased serum bilirubin was a significant risk factor for the delayed neurodevelopment in babies with neonatal jaundice. Even a moderate level of bilirubin significantly affects the developmental outcome.
