... should be noted that the questionnaire did not make provision for the recording of discipline or occupation. Table 3 indicates the frequency at which ergonomics 'problems' are encountered in terms of a mean score (MS) ranging between 1.00 and 5.00, based upon percentage responses to a range 'never' to 'daily'. It is notable that the means of sixteen of the eighteen mean scores are above the midpoint score of 3.00, which indicates that the problems can be deemed to be generally encountered. ...

Studies related to chemical exposure and organ cancer have been carried out with regards to construction workers across the countries. However, few studies include occupational physical stress faced by construction painters in finishing task. Similarly, a handful deals with product design and tool design, that can be used to alleviate their occupational stress. The paper includes literature review of occupational stress experience by construction workers, improvement of work quality, musculoskeletal disorders experienced by construction workers, health issues faced by construction painters, design interventions (tools and equipment) and patents of products and tools designed for construction painters. Multiple combinations of keywords were used which comprised of; construction, physical stress, MSD, ergonomics, painter, worker, high-rise buildings. Several authors have focused on studies related to health issues which deals with effects of noise and fumes on the health of construction workers while others have discussed automation, and few have carried out experimental studies that consist of task analysis, impact of temperature & height on the occupational performance and health of the industrial and construction workers. The article will provide insightful information for medical practitioners, safety & health consultants and industrial designers alike. Keywords: construction, equipment, musculoskeletal disorders, painters.

... Additionally, construction site activities are, reportedly the major causes of health problems to workers (Samuels, 2005). As a result, Smallwood and Haupt (2007) indicated that, while workers were involved in trade related work such as concreting, reinforcing, formwork, structural steelwork, masonry, roofing, building fabric, plumbing and drainage/pipefitting, suspended ceilings, painting and decorating, paving and other external work, ergonomic problems were highly possible. Construction activities and labour intensive methods were fraught with various hazards and risks to workers ( Baradan et al., 2006). ...
Purpose: While construction processes on site involve raw material and labour, they also expose workers to various health and safety challenges. This paper reports findings of the potential impact of prefabrication and pre-assembly on health and safety in construction. Design/methodology/approach: The methodology includes a review of relevant literature on health and safety in construction focusing on the jobsite activities of construction workers and the benefits of prefabrication and pre-assembly. A series of research survey instruments were developed which included both open-and closed-ended questions. These were targeted at designers and contractors in the Western Cape Province. Purposive sampling techniques were used. Findings: The study confirmed that the use of prefabrication and pre-assembly would lead to improvements in construction health and safety performance. The study also confirmed that traditional labour-intensive construction methods exposed workers to more hazards when compared to prefabrication and preassembly. The use of prefabrication and pre-assembly were found to potentially reduce exposure to physical demanding activities and ergonomic hazards on site. Further, reduction of manual material handling would lead to overall improvement of the wellbeing of workers. Research limitations/implications: This particular paper focuses on perceptions of contractors given that they remain responsible for 197 construction work on site and designers due to their responsibility for specifying construction materials. Practical implications: The study increases the awareness of the benefits of prefabrication in South African construction with particular reference to overall improvement of health and safety. Originality/value: This study forms part of M-tech degree which was undertaken in the Western Cape and the findings provide advantages to reduce health and safety threats on site.
Over the last decade, the potential and prospects for using robotics for various construction activities have increased, particularly for dangerous work areas such as roof construction, construction in hazardous environments, and improving productivity while shielding construction workers from strenuous work and accidents. As there have been concerns about human factors in collaborating robotics with humans on construction worksites, ergonomics in human-robot teams’ research is critical to enhancing the advantages and adoption of collaborative robots in improving the productivity of construction workers and the competitiveness of construction organisations. This study reviews the emerging trends in human-robot teams and ergonomics in robotics, focusing on addressing the grey areas in human-robot teams’ body of knowledge. A systematic review of publications from similar industries with extensive studies on human-robot teams and factors applicable to the built environment were identified. The study summarises articles that have emerged over the last decade and highlights the emerging nature of robotics collaboration, ergonomic development and the interplay between robotics design and construction robotics ergonomics. Its outcome benefits AEC research and practice in building knowledge in construction human-robot collaboration, guiding practice and design in robotics by focusing on critical ergonomic issues.
