Full textAbstract:
The study of the motivation of construction workers is limited to a relatively small body of knowledge. Although there is considerable research available regarding motivation and productivity, few researchers have provided a comprehensive analysis on the motivation of construction workers. The research stated that productivity in construction has not improved compared to other industry sectors such as manufacturing. This trend has been echoed in publications throughout the past five decades, and suggested that motivation is one of the key factors impacting productivity. This paper offers a comprehensive review of the published work that directly links the key words—construction and motivation. The findings have been presented in five themes, that is, motivation models, environment and culture, incentives and empowerment, and worker management. This paper concludes with two methods suggested by previous researchers to improve motivation of construction workers: (1) relevant worker incentives (intrinsic or extrinsic) and (2) improved management practices, specifically regarding communication with workers.

Full textAbstract:
For decades, many researchers have reported the decline in construction productivity, but it is impossible to generalize the productivity problems due to issues such as geographical differences, weather changes, skill level differences in the labour force, and workload demand. There are currently approximately 160 000 construction workers in Alberta, and the value of ongoing and future projects in the oil and gas sector alone is over Can$200 billion. Because of the high demand and necessity for a comprehensive research study for Alberta to improve construction productivity, a 2 year study commenced with the collaboration of four eminent contractors to investigate human, management, and external issues. Under human issues, 101 construction workers in the carpentry trade were observed, interviewed, and surveyed by questionnaire. This paper discusses the research method, results, and recommendations of the productivity research specific to the human issues. These recommendations were communicated to the contractors for improving the human issues by developing and analyzing a new expectancy model considering construction workers' effort and performance and the tool times observed to mitigate the reasons for non-tool time.Key words: construction productivity, worker motivation, expectancy theory, tool time, construction workers.

The increasing sophistication and complexity of construction technology have also increased workers’ physical risk and psychological stress. This study examined the relationships between health risks, work motivation, and productivity as perceived by construction workers. A hypothetical model of worker perceptions, and the psychological factors influencing these perceptions, was developed. A total of 324 construction workers at a Japanese construction company participated in the study and were divided into two groups: younger (45 years of age and below) and older adults (46 years of age and above). Data were collected using a questionnaire. The differences between the age groups were analyzed with regard to their perceptions of health risks, motivation, work skills, and productivity. Both younger and older workers were affected by intrinsic motivations and extrinsic motivations, but the effect of these motivations on work performance differed depending on age. Higher health risks are anticipated to affect the work motivation and productivity perceptions of older workers. The proposed model and findings of this study contribute to understanding worker motivations and have important implications for labor management of construction projects. By addressing construction workers’ intrinsic (e.g., interest) and extrinsic (e.g., reward) motivations, it is possible to sustainably improve project productivity.

Full textAbstract:
The work of workers is still dominant in the realization of most construction projects and therefore has a great impact on the productivity of contractors and, thereby, on the sustainability of realization of the goals of contractors and clients. This article provides an overview of the results of more than 100 studies from the previous decade on the impacts of factors related to the personal attributes of workers on the productivity and performance of construction projects. Based on the reviewed literature and semi-structured interviews with experienced professionals in the construction industry, the relation between worker characteristics and other influences on labor productivity is defined and a list of worker characteristics suitable for research in Croatia is compiled. A survey of 262 workers, engineers, and managers from construction industries of Croatia’s eastern region, Slavonia and Baranja, showed that the worker characteristics that most influence labor productivity are experience and dexterity. It was also noticed, with a high correlation between the different groups of respondents, that physical strength and morale and morality of the workers were rated as highly influential, while education level was rated as the least influential. The research results are useful because they indicate the possibility of significantly improving the productivity of construction contractors by selecting workers with appropriate physical abilities and cognitive and non-cognitive skills, as well as developing a suitable system for training and motivation of employees.

Full textAbstract:
The digitalization of the construction industry (CI) has the aim—among others—to raise the bar of overall productivity. The craft workforce is very relevant on the overall value-chain. Therefore, a boost in this dimension impacts the entire sector. There is a gap in proper methodologies to measure and model productivity. Construction 4.0 novelties provide new approaches for its evaluation and progress. This communication presents a review of workforce productivity assessment and delivers methods focusing primarily on craft workers motion monitoring. Products and services opportunities from Construction 4.0 in the spectrum of craft workforce management include support by embedded sensors for data collection that allow near real-time monitoring. The work developed led to the systematization of a framework to standardize craft workers’ motion productivity. The craft workforce motion productivity framework, Worker 4.0, tenders nine processes integrated on a flowchart to streamline task processes assessment and mechanization level. It also sets up a two-handed/two-legged chart system to model craft workers’ activities and operations. The contributions to the body of knowledge are substantiated on the framework creation with the ability to model and assess craft workforce performance. This approach is meant to serve as base point for different stakeholders focusing on skills, efficiency, mechanization and productivity improvements.

PurposeWhile operational factors reduce construction workers' productivity in Zimbabwe, the impact of the people-centred management aspects has not been empirically interrogated as a remedy. This article reports on a study that sought to determine significant people-centred management aspects that lead to improved labour productivity and assesses the existence of statistically significant differences due to the demographic variables of respondents. Demographic-specific strategies that enhance construction “workers” productivity were revealed.Design/methodology/approachThe survey research design using a self-administered questionnaire was deployed to collect the primary data. The design followed a positivist paradigm to evaluate objectively how people-centred management affects construction workers' productivity. The statistical data were descriptively and inferentially analysed.FindingsPeople-centred management was determined to be significant in improving construction workers' productivity, with the most significant aspect being the building of employee confidence in related approaches. Designations and educational levels mostly indicated a statistically significant difference in several aspects that included the adoption of a functional reward culture for workers and training on people-centred principles. Training on-site management and construction workers in people-centred management and its application are crucial to improving construction workers' productivity.Research limitations/implicationsConstruction companies should drastically improve their concern for people while they sustain a high concern for production within their construction sites. Although several factors affect construction workers' productivity, this study determined that management-related factors and people-centred management were significant towards influencing low productivity in Zimbabwe.Originality/valueThe study determined people-centred management and demographic-specific interventions as being able to improve construction workers' productivity in Zimbabwe.

Full textAbstract:
The aim of this study is to build a mathematical model of the productivity of construction workers. It does so by selecting 17 factors that influence the productivity of construction workers and categorising them into five groups. For the mathematical description of the factors, fuzzy logic was used. A formula for calculating the work productivity of construction workers is proposed. The novelty of the approach proposed by the authors is rooted in the consideration of various factors that have the potential to influence the productivity of construction workers. To present the way the formula operates, a single assessment of ceiling formwork was undertaken. The verification of a model confirmed its capability of analyzing, evaluating, and predicting the productivity of construction workers with satisfying accuracy.

Objective: The objective of this article is to investigate the influence of human parameters on qualitative assessment of labor productivity (LP) in the construction industry. Background: The theories involving workers have identified various parameters on physical efficiency, such as heart rate, relative heart rate, and calorie count, so as to improve the safety and social conditions of construction labor, thereby increasing LP. However, there is no direct emphasis on assessment of LP using human parameters related to physical strength. Method: An exploratory study was conducted on 17 construction workers by observing their task-level LP in real time at a construction site. Human parameters, such as age, body mass index (BMI), handgrip strength, and upper body muscle strength of the laborers, were measured at the construction site. Performance levels of these workers were placed in three categories, and each worker was assigned a typical weightage to each category when correlated to physical strength. Results: Labor categories among the human parameters that included middle age, normal-range BMI, and strong muscular strength were shown as having higher LP than others. A quantitative parameter called the Human Parameter Index (HPI) was developed based on the performance categories developed for an individual worker. Human parameters revealed a significant relationship with respect to task-level LP. Conclusion and Application: The study determines the influence of human parameters on LP in construction. Introduction of human parameters in the construction industry will help in assessment of LP for various labor-intensive activities.

The construction industry is a work environment that poses many dangers to workers, with many hidden factors that affect work awareness. It is important for construction companies to ensure a balance between productivity and safety in the work environment. The purpose of this study was to identify relationships between the feeling of safety in the work environment, proactive work behavior, job satisfaction, work skills, team performance, and health risk indicators, such as heart rate, among construction workers of different ages. Based on previous research, we examined the hypothetical perception model. We then administered a questionnaire survey to construction workers (N = 357) employed at a Japanese construction company. Using structural equation modeling (SEM), we investigated the impact of health risk indicators on worker perceptions among young and older workers. The results showed that workers’ heart rate and body mass index (BMI) had a negative effect on the feeling of safety and proactive work behavior among older workers, but showed no significant relationship among young workers. However, regardless of workers’ age, it was clear that the feeling of safety affects job satisfaction, and that work skills and proactive work behaviors affect perceptions regarding team performance.

Full textAbstract:
Purpose – The aim of this study is to explore the impact of using foreign workers on construction productivity in project situations. Generally, foreign-funded projects use both native and foreign workers. Foreign workforce entering into the construction industry may affect the productivity positively or negatively, depending on the migrants’ attributes, institutional arrangements and native workers’ responses, thereby impacting the cost of the project. In Sri Lanka, large construction sites have become multicultural and depend on foreign workers brought in by foreign contractors for infrastructure projects. Design/methodology/approach – A survey-based approach was used to collect data. Structured interviews were conducted to explore the characteristics of the foreign workforce and their impact on productivity. Further, potential strategies were analyzed to establish industry motivators (IM) to enhance productivity. Findings – The study on the foreign workforce identified ten employee characteristics that may impact project’s productivity either positively or negatively. Further, 16 significant strategies were compiled to establish six IM to enhance productivity. Originality/value – These proposed motivators will be useful for construction practitioners in mitigating negative impacts and proactively managing the foreign workforce in a way to enhance construction productivity.

Full textAbstract:
Purpose – Raise in temperatures due to climate change is likely to increase the heat stress in occupations that are physically exerting and performed outdoors which might potentially have adverse health and productivity consequences. The purpose of this paper is to estimate the productivities in construction work under the influence of heat stress using the predicted mean vote (PMV) index. Design/methodology/approach – Field studies were conducted during May 2014 which is summer time in Chennai. Continuous heart rate of workers and wet bulb globe temperature measurements are conducted for workers engaged in different jobs in construction. Metabolic rates and the workload of the workers from heart rate were calculated using the ISO method 8996 and the PMV values are calculated using the tool developed by Malchaire based on the method ISO 7730. Direct observations and personal interviews were conducted to substantiate the productivity estimations. Findings – The results showed that workers working outdoors with moderate and heavy workload exceeded the threshold limit value of 28°C and had adverse productivity impacts (18-35 per cent productivity loss), whereas the workers engaged in light indoor work was not affected by heat stress and consequent productivity losses. The productivity estimations using the PMV index is found to be statistically significant for three types of construction works (Pearson correlation coefficient value of −0.78) and also correlated well with the observations and self-reported productivities of the workers. Originality/value – The method used in this paper provides a scientific and reliable estimation of the productivities which may benefit the industry to set realistic project completion goals in hot weather and also implement interventions and policies to protect workers’ health. Developing adaptive strategies and implementing control measures are the need of the hour to protect worker’s health and economic losses in the face of climate change.

Full textAbstract:
Purpose The construction industry is dynamic and often unregulated due to its complex, project-based nature. This makes the task of implementing human resource management (HRM) functions more difficult than in other economic sectors. This is particularly the case for developing countries which rely on a migrant, casual, and transient workforce. Despite offering flexibility, a transient workforce can lead to unpredictable rates of absenteeism and unsatisfactory productivity. This paper links HRM practices in the construction industry of the developing world to rates of absenteeism across three segments of the construction workforce – foremen, skilled workers, and unskilled workers. The paper aims to discuss these issues. Design/methodology/approach A survey targeting 60 construction sites in Beirut, Lebanon form the basis of the analysis. Within each site, measures of absenteeism for foremen, skilled, and unskilled workers were solicited along with other data on HRM onsite. Findings The results suggest a regression model for worker absenteeism based on tenure of work as well as the absenteeism of workers at the next hierarchical level onsite. Originality/value This study is among the first to show a link between the mechanisms by which construction workers are employed (contract-based foremen vs daily/weekly labourers – both skilled and unskilled) and the rate of absenteeism seen onsite. Given the role of absenteeism in construction productivity, having a good understanding of the underlying causes of absenteeism is critical to the design of mitigating policies.

Productivity in the construction industry is declining in real-time. The decline in productivity is a source of worry for practitioners and researchers. The purpose of this paper is to ascertain major factors influencing productivity in relation to the notion of respects for people (RFP) in construction. The reviewed literature influences the semi-structured questionnaire used to survey construction professionals in Johannesburg, South Africa. The results reaffirm the tension productivity increment and the enhancement of RfP as both ideas appear to be moving in opposite directions on a typical construction site. It was discovered that respect for workers on a construction site is a major concern. The paper argues that ethical reasoning affects productivity. Therefore, an appropriate management system is required to improve the workers' perception of productivity and RfP working on construction sites.

Full textAbstract:
Purpose The purpose of this paper shows the effect of hot and humid weather conditions (HHWCs) on workers that has resulted in considerable loss in the construction industry, especially during the hottest periods due to decline in worker productivity (WP). Until the last few decades, there is very limited research on construction WP in HHWCs. Nevertheless, these studies have sparked interests on seeking for the most appropriate methods to assess the impact of HHWCs on construction workers. Design/methodology/approach This paper begins by reviewing the current measuring methods on WP in HHWCs, follows by presenting the potential impact of HHWCs on WP. The paper highlights the methodological deficiencies, which consequently provides a platform for scholars and practitioners to direct future research to resolve the significant productivity loss due to global warming. This paper highlights the need to identify the limitations and advantages of the current methods to formulate a framework of new approaches to measure the WP in HHWCs. Findings Results show that the methods used in providing real-time response on the effects of HHWCs on WP in construction at project, task and crew levels are limited. An integration of nonintrusive real-time monitoring system and local weather measurement with real-time data synchronisation and analysis is required to produce suitable information to determine worker health- and safety-related decisions in HHWCs. Originality/value The comprehensive literature review makes an original contribution to WP measurements filed in HHWCs in the construction industry. Results of this review provide researchers and practitioners with an insight into challenges associated with the measurements methods and solving practical site measurements issues. The findings will also enable the researchers and practitioners to bridge the identified research gaps in this research field and enhance the ability to provide accurate measures in HHWCs. The proposed research framework may promote potential improvements in the productivity measurements methods, which support researchers and practitioners in developing new innovative methods in HHWCs with the integration of the most recent monitoring technologies.

Full textAbstract:
Total factor productivity (TFP) is of critical importance to the sustainable development of construction industry. This paper presents an analysis on the impact of migrant workers on TFP in Chinese construction sector. Interestingly, Solow Residual Approach is applied to conduct the analysis through comparing two scenarios, namely the scenario without considering migrant workers (Scenario A) and the scenario with including migrant workers (Scenario B). The data are collected from the China Statistical Yearbook on Construction and Chinese Annual Report on Migrant Workers for the period of 2008–2015. The results indicate that migrant workers have a significant impact on TFP, during the surveyed period they improved TFP by 10.42% in total and promoted the annual average TFP growth by 0.96%. Hence, it can be seen that the impact of migrant workers on TFP is very significant, whilst the main reason for such impact is believed to be the improvement of migrant workers’ quality obtained mainly throughout learning by doing.

Full textAbstract:
With the rapid development of deep learning, computer vision has assisted in solving a variety of problems in engineering construction. However, very few computer vision-based approaches have been proposed on work productivity’s evaluation. Therefore, taking a super high-rise project as a research case, using the detected object information obtained by a deep learning algorithm, a computer vision-based method for evaluating the productivity of assembling reinforcement is proposed. Firstly, a detector that can accurately distinguish various entities related to assembling reinforcement based on CenterNet is established. DLA34 is selected as the backbone. The mAP reaches 0.9682, and the speed of detecting a single image can be as low as 0.076 s. Secondly, the trained detector is used to detect the video frames, and images with detected boxes and documents with coordinates can be obtained. The position relationship between the detected work objects and detected workers is used to determine how many workers (N) have participated in the task. The time (T) to perform the process can be obtained from the change of coordinates of the work object. Finally, the productivity is evaluated according to N and T. The authors use four actual construction videos for validation, and the results show that the productivity evaluation is generally consistent with the actual conditions. The contribution of this research to construction management is twofold: On the one hand, without affecting the normal behavior of workers, a connection between construction individuals and work object is established, and the work productivity evaluation is realized. On the other hand, the proposed method has a positive effect on improving the efficiency of construction management.

<span lang="EN-US">The evolution of technology has changed the way how human communicate in the current time. With the advancement of technology, instructions and messages could be delivered in a split second. Even though life is made easy with technology, some information and details should be delivered face-to-face in order to avoid communication breakdown. This study was carried out to determine the language needs by foreign workers working at construction sectors in Malaysia. The study created an overview on how communication affects productivity in completing tasks on time. The results from this study lead to a development of language modules for foreign workers training. An online survey was carried out through social media on construction site supervisors around Malaysia in getting their feedback related to the origin of their co-workers and the importance of English language as medium of instruction for task fulfilment. Results indicated that language barriers had affected productivity in the sector of construction in Malaysia. Besides, results also noted that cross-cultural differences had put foreign workers at risk and caused wastage to time and manpower.</span>

Full textAbstract:
Purpose This paper aims to identify the impact that commute patterns pose on construction labour productivity (CLP). There is limited research focussed on the impact of workforce transportation on productivity, even fewer in a construction environment. In particular, this study seeks to fill a gap in the understanding of how commute patterns may influence CLP. Design/methodology/approach Key factors reported affecting CLP were identified through a comprehensive literature review. Data were collected from 27 interviews and observational evidence at construction sites on Auckland Central Business District (CBD). Findings Shortage of skills, communication among workers, shirking behaviour, absenteeism and tardiness were perceived as the most critical labour productivity factors that are influenced by commute patterns. It is considered that stressful commutes may lead to shirking behaviours (absenteeism and calling sick). Meanwhile, ridesharing may encourage communication among workers. Research limitations/implications The study was carried out in a central business district, focussing on a geographic area with its particular characteristics. The results, thus, may not be generalised in general urban settings. Originality/value The research outcomes can be used as guidelines for companies considering travel plans for their employees, to minimise the negative impact commuting can have on workers, especially in industries with low productivity.

In the construction industry, the direct workforce is one of the most important drivers of the work process. Identifying and quantifying labor productivity impact factors allows the diagnosis of recurring problems during the construction phase. Understanding how these factors influence the productive and the nonproductive states according to the characteristics of workers or group of workers is an essential tool to boost productivity. This paper introduces a multivariate statistical analysis approach to cluster workers based on the characteristics of the actions that are performed during the daily construction tasks. This study analyzed the data from a field experiment based on human observation of actions of 10 welders during a week in a pipe-shop. The case study conducted step by step presented in this work indicates retention of 50% and 40% of the total sample in segmented workers clusters.

Chinese construction industry, a vital part of Chinese economy, is meaningful to absorb a large number of human resources. But with the rapid development of gross product of construction industry, labor productivity dose not increased considering construction worker as input resource. For the effective implementation of human resource policies, in this paper, based on the factor analysis theory and intelligent technology, a hybrid model of PCA and Least Squares Support Vector Machines are combined to predict the rational scale of construction workers. Relative data is collected from National Bureau of Statistics of China. Data analysis shows the proposed models, especially based on LS-SVMs, have more steady performance and higher accuracy.

Purpose Investigating demands within an occupational context has always been an essential endeavor to guarantee worker well-being and performance efficiency. In blue-collar occupations, the physical demands of manual labor have always been the major focus, but recent technological changes may come with higher demands on the intellectual capacities of workers. For this reason, the purpose of this paper is to assess physical and cognitive demands that construction workers face. Design/methodology/approach The authors conducted a quantitative study using standardized research instruments. Construction workers of three German construction companies were asked to volunteer to participate in interviews (n=35) and a survey (n=30) that assessed the extent of physical demands and a variety of cognitive demands experienced by construction workers. Findings The results suggest that construction work is demanding in physical terms as well as in perceptual, psychomotor, social and cognitive terms. Using and updating specialized knowledge, giving advice and providing consultation, friendliness, assertiveness and reliability are important demands among construction workers. Research limitations/implications Construction workers face an undervalued level of demands in their everyday work environment. As high demands can affect well-being and mental health, construction companies would greatly benefit from investing efforts into evaluating the multi-component demands profile of their workers and the impact on their health, in particular through the strongly increasing cognitive demands due to the ongoing digitization of the sector. Originality/value The study identified essential demands in construction work that are relevant for the workers’ productivity and well-being.

Although the current economic downturn has eased the stress of broad skilled labour shortages, it is reasonable to believe that the shortage will return when the U.S. economy rebounds. The shortage could become more substantial because the U.S. construction industry is poised to make a significant demographic shift with Baby Boomer workers approaching retirement and Generation Y workers joining the workforce. This paper investigates how different generations of craft workers perceive the factors affecting labour productivity. The data was collected through a survey of 1996 craft workers on 28 U.S. construction sites in 2004 and 2005. The analysis results reveal that: (1) Generation Y, Generation X, and Baby Boomers actually have consensus on the relative impact of productivity factors; and (2) significant differences were also observed on individual productivity factors and the primary differences among the generations were associated with tools and consumables, labour, engineering drawing management, and project policy.

Full textAbstract:
Purpose – Surprisingly, given the prominence and front-line role of subcontractors in the construction industry, their perspective is almost completely absent from construction productivity literature. Existing research in this area presents a highly one-sided principal contractor perspective and there are very few insights into what subcontractors think. The purpose of this paper is to address the imbalance by investigating the determinants of construction productivity from a subcontractor's perspective. Design/methodology/approach – Focus groups with 71 of Australia's leading tier-one subcontractors were conducted with the aim of exploring their insights into the productivity challenge. Findings – The findings indicate that the main determinants of productivity for subcontractors are: the quality of relationships with principal contractors; opportunity for early involvement in design; transparent tender practices; growing administration and document control; design management; project management and supervisory skills, particularly in planning, scheduling and coordination; risk management and; industrial relations (IR). Research limitations/implications – This research was conducted in Australia and similar research needs to be conducted in other countries to cross-reference and validate the results more widely. Practical implications – In practical terms, a “culture” of productivity improvement will need to be “nurtured” across the business and supply chain if productivity is to be improved. In particular contractors should avoid bid shopping, respect subcontractor IP and talk to subcontractors earlier in a project. Social implications – By respecting the opinions of subcontractors who employ the vast majority of workers in the construction industry, productivity and employment can be increased. Originality/value – The focus group results add significantly to a more balanced understanding of what has hitherto been a one-sided principal contractor focused debate.

Full textAbstract:
In highway construction projects, labor-oriented work is an integral part of the management process, requiring analysis of factors affecting labor productivity during Covid-19 pandemic. This research identified 53 influential factors affecting construction labor productivity at selected cities and towns in Cagayan Valley Region, Philippines. Due to the pandemic, the construction industries incurred substantial profit losses. More so, the construction workers are too much affected because of the Enhance Community Quarantine (ECQ) imposed by the local government. Results indicated there was laxity on the Covid-19 protocols. No health worker in the project site ranked the highest in the health & safety factor group with an RII of 0.97 and ranked 1st among 53 factors on the different groups. Besides, no safety engineer was assigned to the projects and ranked 2nd with an RII of 0.93. Among the 7 groups of factors, the health and safety group ranked 1st with 0.81, followed by the schedule compression group with an RII of 0.78. Hence, these two groups of factors have a strong relationship, as evidenced by number of workers reduced. It was learned that the contractors’ strategy was to increase the number of working days to cope with their schedules. Hypothesis testing supported that there are various significant factors influencing labor productivity loss during the Covid-19 pandemic, as suggested by more than 50% of the respondents.

Skilled construction workers are crucial to the successful delivery of construction projects. However, there have been reports of their shortage within the Nigerian construction industry. Ensuring commitment of the few available ones to their organisation is important as this is bound to influence the service delivery of these organisations. This paper presents the result of the assessment of the organisational commitment of skilled construction workers in Abuja, Nigeria. A quantitative survey design was adopted, and data were gathered from selected skilled construction workers in 31 construction companies registered with Nigeria's Federation of Construction Industry. Organisational Commitment Scale was adopted in assessing the commitment of these set of workers, and data were harnessed through the use of a questionnaire. Percentage, mean item score and Kruskal-Wallis H-Test were used in analysing the data gathered. Cronbach Alpha test was also conducted to test the reliability of the research instrument. The study revealed that the common type of commitment exhibited by skilled construction workers is the continuance commitment. Factors such as getting feedback from supervisors, payment received being equal to work done, and the availability of opportunities to grow, play a major role in the commitment type being exhibited. The practical implication of this result is that construction companies within the country need to improve in the aspect of human resource management to attain better commitment and at the same time improve their productivity. It is believed that the findings of this study will assist construction organisations in adopting the right method that will help enhance the organisational commitment of their skilled workers.

The use of large electric hammer and pneumatic drills exposes construction workers to high levels of hand vibration that may lead to hand arm vibration syndrome and other musculoskeletal disorders. This hammer drill test bench study demonstrated a small but significant increase in z-axis handle vibration (4.8 to 5.1 m/s2; ISO weighted) and drilling time per hole (7.8 to 12.3 s) with worn concrete bits when compared to a new bit. Drill bit manufactures may consider advising contractors that worn bits will increase the exposure of workers to hand vibration and will reduce worker productivity. Construction contractors should adopt a bit replacement program based on bit wear patterns in order to reduce exposure level and drilling time to hazardous hand vibration.

Poor productivity of construction workers is one of the causes of cost and time overruns in construction projects. As construction is a labour-intensive industry, this paper focuses on labour productivity in the construction industry and to identify factors affecting labour productivity at building construction project. The performance of labour is affected by many factors and is usually linked to the performance of time, cost, work pressure, safety measures and quality. The questionnaires were distributed to supervisors, project Engineer, labourers, the top 35 factors were identified, categorized into 3 different groups, using SPSS tool, which is analytical software, the factors were analyzed and ranked considering relative importance index were calculated. And also calculated actual productivity for Brick Masonry is taken from sites. The result shows the factors considered which most affects the labour productivity loss in residential buildings and actual productivity versus expected productivity the brick masonry work were calculated.

Construction work, as well as other production process depends on how people work towards it. The success of the work is determined by labor productivity. Labor productivity is affected by many factors such as human factors, environment, labor condition, leadership, type of work, level of difficulty etc. This article will discuss how these aspects influence the value of labor productivity. We limit our research on wage, age and experience from 15 to 30 workers in the brick work. The research is held in 4 construction sites in Kota Langsa, Aceh, Indonesia in late 2016 until early 2017. We observe the effective time, time of contribution, ineffective time work and the work volume. Productivity is obtained by dividing the work volume and the effective time work. The result shows that the amount of wage influences the labor productivity. Nonetheless, we found that age and experience do not affect labor productivity. Interestingly, the experience workers in any ages will increase the value of labor productivity.

Full textAbstract:
System form is widely used when constructing concrete buildings and structures because it has high productivity and good concrete casting quality compared with traditional hand-set form. However, from a worker’s perspective, system form is still very harsh to handle because of its heavy weight, noise generation, and use of releasing agent, and it also attenuates the productivity of system formwork. Therefore, this study proposes the use of an advanced composite material-based concrete form for workers using a Design for Six Sigma (DFSS) process to improve constructability of system formwork. User requirements are systematically reflected in the technical characteristics of concrete form, and innovative principles are scientifically organized through the DFSS process that mainly consists of quality function deployment and theory of creative problem-solving methods. The proposed composite form showed improved performance in deriving high-quality formwork and worker-friendly working conditions compared with previous system forms. Additionally, this study demonstrated how the DFSS will be a valuable tool for technology development and systematic decision-making in building construction.

Poor productivity of construction workers is one of the causes of cost and time overruns in construction projects. The productivity of labour is particularly important especially in developing countries, where most of the building construction work is still on manual basis. This paper reports on a survey made on project managers of building projects in Uganda, where an increase in productivity is being sought. Respondents were required to rate using their experience how 36 factors affect productivity with respect to time, cost and quality. The survey was carried out by a questionnaire and responses received over a period of 3 months. The ten most significant problems affecting labour productivity were identified as incompetent supervisors; lack of skills from the workers; rework; lack of tools/equipment; poor construction methods; poor communication; inaccurate drawings; stoppages because of work being rejected by consultants; political insecurity; tools/equipment breakdown; and harsh weather conditions. Although lack of materials is ranked highest with regard to average rating on loss of time, it was not ranked among the top ten using the importance index that takes into account time, cost as well as work quality. The policy makers and researchers should focus on the identified major factors in order to improve productivity.

Full textAbstract:
The paper reviews the dependence of labor productivity on the number of workers within a unit of working area (i.e. workforce density) in the construction sector. The relevance of the problem is demonstrated. Some limitations of the linear model for the dependence, assumed in the construction sector, are discussed. These limitations are linked up with the neglect of labor productivity reduction due to the increased density. The proposed by some researchers concepts which account for the above factor are listed. Their drawbacks are indicated, and the necessity of further research is shown. A “hyperbolic model” is proposed, in which one worker productivity is constant for a certain workforce density rate and then it drops down with the increasing speed. Work productivity reduction in such model is described by the “hyperbolic growth” function. The primary approbation of the model was done for some construction operations at the nuclear power plant reactor building. The density rate was optimized (as per deadline reduction criterion) for this case according to the “hyperbolic model”.

Full textAbstract:
Purpose The purpose of this paper is to focus on productivity as it unfolds during the execution of a particular task, i.e., reinforced concrete operations. The main aim is understanding whether the learning effect explaining the improvement of productivity in subsequent cycles of a given repetitive construction process is mainly attributable to a pure worker learning (independent on the specific site) or to the experience developed by the crew on the site conditions. Design/methodology/approach The authors conduct a research that empirically investigates and compares the change in productivity data of a single worker during his/her working life and that of a crew involved in specific repetitive work, such as the concreting activities of a multi-storey building. Findings The findings suggest differentiating between productivity gain as a result of the learning effect of the individual worker throughout his/her working life (which is independent of the specific project and site) and that of a crew composed by more workers which repeat reinforced concrete operations in a given specific project. Research limitations/implications Despite the great attention reserved to learning in construction, few researchers discuss on the real applicability of the learning curve (LC) theory in the construction industry. The authors contribute to this literature by empirically investigating the contributions that the learning effect of the individual worker and that of a crew repeating a given task (i.e. reinforced concrete operations) in a given project have on the productivity improvement for subsequent cycles of the repetitive construction process. Practical implications The findings of this study have important managerial implications. The shape of the LC of the individual worker implies that learning increases relatively slowly in his/her working life (particularly after one to two years), while the effects of the crew experience are immediately significant in a time range of few weeks. This means that a single “one-off” multi-storey building project will show in the first storey the “historical,” individual productivity of the individual workers (i.e. not going to vary significantly in the next few weeks). The productivity improvement in the further storeys will only depend on the project-specific (and collective, for the crew) “learning” due, for example, to better coordination or to other issues that are progressively solved moving from the first storey to the following ones. So, the project-specific LC increases in a faster way than the individual one, and the overall productivity can be improved by accelerating the project-specific learning rate with more accurate project-specific design and management. Originality/value This paper enhances the understanding of the contributions that the learning effect of the individual worker and that of a crew repeating a given task (i.e. reinforced concrete operations) in a given project have on the productivity improvement for subsequent cycles of the repetitive construction process. This will contribute to improve the planning and control of site work activities, avoiding time and money wastefulness.

Full textAbstract:
A recent study on construction productivity improvement at the University of Calgary revealed the direct tool time (working time) of Alberta’s commercial construction to be about 51%. This study exposed inadequate communication and unavailability of required information as the main causes for a relatively lower tool time. Use of information technology (IT) to overcome widely visible communication issues was extremely limited at the construction site level. Construction companies’ hesitation to adopt new technologies was well noted whereas construction workers expressed their willingness and ability to use IT at the site level. The objective of this paper is to discuss the concept and the application of a novel communication tool (called an information booth) developed and pilot tested at a construction project. The concept and the technology presented in this paper have been tested at an actual construction project resulting in improvements in construction productivity, worker satisfaction, and efficiency. This paper also elaborates the rationale for a new technological framework (and the information booth), barriers for technology implementation, research objectives, methodology, and data analysis.
