In this research, factors affecting construction labour productivity in Zaria, Kaduna state was assessed. The research seeks to identify the factors affecting labour productivity in the research area. It is believed that this information will aid site managers and the construction professionals on decisions to take in-order to limit these controlling factors thereby leading to an improved level of efficiency in labour force, increase product labour productivity and reduce cost and time over runs on construction projects. The research adopted a quantitative research approach with the use of questionnaires as an instrument for data collection from site managers at construction sites in Zaria. Sixty-seven questionnaires were administered on construction sites within Zaria and Forty-one were returned giving a sixty-one percent response. The Questionnaire sought to assess the perception of site managers on factors affecting construction labour productivity. Data was analysed using descriptive statistics analysis to obtain frequencies, mean and Relative Importance Index (RII). RII was used to rank the factors. Thirty-Nine out of the Forty-One factors researched indicated high severity with the RII ranging between 0.60 RII < 0.80. The research revealed that external forces tend to affect construction labour productivity more than Site factors and Human Labour Factors. This can be attributed to the fact that site factors and Human Labour factors can be controlled by the site engineers while the external factors cannot be really controlled by the site engineers. The survey also revealed that Rain, Conflict with project stakeholders, Skill of labour, and Financial Crisis had a very high severity in affecting construction labour productivity on the construction sites in Zaria, Kaduna State.

 Buildability is an important factor affecting labour productivity. Nevertheless, a thorough search of the literature revealed a dearth of research into its effects on in situ reinforced concrete construction, especially at the activity levels. Since rebar fixing is an integral trade of this type of construction material, and beamless slabs are amongst the major encountered activities on construction sites, the objective of this research is to explore the buildability factors affecting its rebar fixing efficiency. To achieve this objective, a large volume of fixing productivity data was collected and analysed using the categorical interaction - regression method. As a result, the main and interaction effects of rebar diameter; reinforcement quantity; slab geometry; and reinforcement layer location are determined. The findings show a significant influence of these factors on the fixing operation, which can be used to provide designers and construction managers with feedback on how well the design of this activity considers the requirements of buildability, and the tangible consequences of designers‟ decisions on labour productivity

Productivity is a very important element in the estimation process in construction management. The objective of this research is to identify and analyze the factors which affect labor productivity in construction projects. In this research, 42 effective factors were collected from site survey, interview with engineers and experts, and previous research in the Arab world. These factors are grouped into Nine categories “Workforce, Leadership, Motivation, Supervisors, Safety, Project, Time, Material, and External”. A survey questionnaire of 70 respondents was distributed among different experts. A statistical analysis was done using SPSS and EXCEL packages. The Relative Importance Index was used to find out the most significant factors affecting the labor productivity in construction sites. The results accomplished from the survey revealed that the major factors negatively affect the labor productivity (ranked from the worst factor with Relative Importance Index values, respectively) namely, Availability Material (88.571%), Climate status “Weather” (88%), Religious occasions (86.29%), Number of working groups (86%), Ganger experience (85.714%), Workforce surveillance (84.857%), Ganger Age (84%), working at height (82%), Drawings and specifications alteration during execution (81.69%), and Sequence of floor (80.571%). Based upon these findings, this can help the construction professionals to improve the productivity and project performance in Iraq.

Organisational Effectiveness

Orientation: Globally, people engage in work and sell their services to an organisation in exchange for compensation. This compensation can have a significant effect on employees’ attitude towards their work, resulting in either job satisfaction or job dissatisfaction. A high level of job satisfaction can increase organisational effectiveness and, subsequently, the organisation’s performance, whereas job dissatisfaction can cause employees to be less motivated, which can in turn decrease their productivity, effectiveness and individual performance.Research purpose: This study was conducted with the aim to investigate undergraduate students’ perceptions of the factors affecting job satisfaction.Motivation for the study: Currently, there is a paucity of published research on the views of undergraduate students on the factors affecting job satisfaction.Research approach/design and method: The study took a positivistic research approach, and a quantitative design was used. A stratified quota sampling technique was employed to select the respondents for the study; a certain quota was met in terms of race, gender and faculty of study. In total, 270 undergraduate students participated in the study.Main findings: The empirical results indicated no significant association between the demographic variables (previous work experience, gender, race and field of study) and almost all occupational dimensions of job satisfaction, working conditions and recognition. However, medium to large positive relations were measured between the dimensions of job satisfaction, working conditions and recognition. It was evident from the study that all the dimensions measured are considered important for obtaining job satisfaction in the workplace.Practical and managerial implications: It is important for managers to get an understanding of the views of young people on work-related issues in order to create an understanding of young people’s needs and aspirations, as they are the future permanent labour force, managers and leaders of a country.Contribution/value-add: The study brought to light the views of undergraduate students on the factors affecting job satisfaction.

A successful construction project has many important components, one of which is labour. Many construction projects fail to achieve their goal due to poor labour productivity. Thus, this research evaluated labour productivity on building projects based on the perception of site managers. The objectives identified the factors that affect the productivity of construction operatives, examined the importance of factors affecting labour productivity, assessed the management policies to improve productivity of workers on site, and suggested solutions to the problem of labour productivity on building sites. The sample frame consisted of the 26 construction organizations registered with Lagos Chamber of Commerce and Industry (L.C.C.I). Random sampling technique was used to administer 62 questionnaires to site managers of the building projects of the 26 construction organizations in the frame. Data obtained were analysed using frequency, mean and relative importance index. The findings showed that topmost among the factors that affect labour productivity are clarity of technical specification, equipment shortages, skill of labour, coordination level among design disciplines, payment delay, and material shortage with mean values of 4.24, 4.20, 4.20, 4.17 and 4.17 respectively. Training, welfare amenities and specialization with mean values of 4.36, 4.02 and 4.00 ranked highest among the management policies for improving operatives’ productivity. It is recommended that operatives should have access to equipment; payment should also be done promptly; in addition to organizations supporting operatives on regular training on relevant skills

Background: Pulses are one of the most important food crops grown globally owed to their higher protein content. It also accounts for larger financial gains of the agricultural sector by amounting for a large part of the exports. The present study was carried out to determine the factors affecting production of pulse crops in Rajasthan. Methods: This paper based on secondary data collected over the years i.e. from 2000-01 to 2017-18. The Cobb-douglas production function was used to the observation for the estimation of elasticity of selected variables contributing to the production of pulses in Rajasthan state, Cobb douglas type production function was employed to assess the effects of seed, fertilizer, manure, human labour, irrigation, bullock labour and plant protection measures on pulses production. Result: The results from the study have shown that fertilizer and plant protection measures were positively significant while the variable corresponding to irrigation water was negatively significantly affecting the gram production. The variables such as seed and irrigation water were found positive and significant, while plant protection measures had significant negative effect on black gram production. Only two variables namely, fertilizer and irrigation water were found positively significant out of estimating production function of green gram.

Construction Accidents

Introduction: Research indicate that construction site accidents are a global concern, and rates are rapidly increasing. In developing countries such as Saudi Arabia, safety issues are frequently ignored, and little is known about their causes. Objectives: This study aimed to shed light on factors causing accidents in Saudi Arabian construction companies. Methods: An online detailed survey, using Google Form, of accident features was distributed randomly to potential employees in 35 construction companies in Saudi Arabia, where one of the top administrators or safety officers were required to respond to the survey. It was conducted from 1st June to 31st August, 2013. The safety practices and perceptions of accident causes were assessed. Results: The response rate was 63%. Over half of the surveyed organizations encountered all of the selected accident types. While 19 (86%) of the construction companies maintained the equipment regularly, 15 (68%) had regular maintenance staff and 13 (59%) inspected the equipment before use. Although 18 (82%) of the workers were supplied with personal protective equipment (PPE), only 12 (55%) emphasized its use and offered site orientation for new employees.  In the last part of the survey, respondents were requested to rate 25 factors affecting safety performance at the construction sites on a scale of 1 to 5, with 5 being the most important. The three most important factors of poor safety performance were the firm's top leaders, a lack of training, and the reckless operation of equipment. Conclusion: Changing attitudes of surrounding safety culture have the potential to significantly improve safety outcomes in the Saudi Arabian construction industry. Two Saudi Arabian corporations, Saudi Aramco and Saudi Chevron Petrochemical provide a positive model for increasing construction safety in the country, but there is a paucity of industry-level data. Further scholarly attention is strongly indicated.
