“…Additionally, productivity is measurable at several levels (Kenley, 2014); from macroeconomic measures at the industry level which combine projects (Nasir et al, 2014) to microeconomic measures at the project level which combines activities and at the activity or task level (Meikle and Best, 2015).…”

Does Compatibility of Personality Affect Productivity? Exploratory Study with Construction Crews

2020

Crew productivity is a function of how efficiently labor is utilized in the construction process. However, previous research in construction has not comprehensively investigated the relationship between personality and crew productivity. This paper uses personality profiles to investigate a new fundamental concept, the relationship between compatibility of personality and crew productivity at the task level. Twenty-eight masons completed a revised questionnaire of the big five to indicate their personality. Personality scores were used to calculate compatibility in each of the 20 participating two-mason crews working on eight projects. Regression analysis was performed to establish the relationship between compatibility and crew productivity. Results show that that there is a high positive correlation between compatibility and crew productivity. Compatibility accounts for more than half of the predictable variance in productivity. This paper makes four major contributions: it proposes a new metric to measure compatibility of personality among workers in a crew; it reveals how personality factors affect productivity; it provides rigorous methods to analyse correlations (using confidence intervals and Bayesian inference) for construction experiments; and it provides theoretical contributions to advancing the theory of personality and productivity in construction projects.

“…The industry has also been challenged for poor performance on productivity. For example, Nasir et al (2014) compared the labour productivity of 20 countries and found that the US showed the worst performance with an annual compound rate of -0.84%. The low productivity issue has also been found in other developed countries, such as UK (Abdel-Wahab et al, 2008), Singapore (Lim and Alum, 1995) and Hong Kong (Lo et al, 2006).…”

9 3-D printing, which is an automated production process with layer-by-layer control, has been gaining rapid development in recent years. The technology has been adopted in the manufacturing industry for decades and has recently been introduced in the construction industry to print houses and villas. The technology can bring significant benefits to the construction industry in terms of increased customization, reduced construction time, reduced manpower and construction cost. A few isolated products and projects have been preliminarily tested using the 3-D printing technology. However, it should be noted that such tests and developments on the use of 3-D printing in the construction industry are very fragmented at the time of the study. It is therefore necessary for the building and construction industry to understand the technology, its historical applications and challenges for better utilization in the future. A systematic review shows that 3-D printing technology, after years of evolution, can be used to print large-scale architectural models and buildings. However, the potential of the technology is limited by the lack of large-scale implementation, the development of building information modelling, the requirements of mass customization and the life cycle cost of the printed projects. It is therefore expected that future studies should be conducted on these areas to consolidate the stability and expand the applicability of 3-D printing in the construction industry.

“…There is no single definition that can entirely describe productivity in a complex sector like the construction industry (Rane et al, 2017). Nasir et al (2014) opine that the reason for this is because different inputs and outputs are involved in different projects and organizations. For equipment-intensive construction operations, productivity is defined as output / input (i.e.…”

Despite myriad of research effort directed at improving the performance of construction projects, poor productivity, budget overruns, quality related issues, and schedule overruns have been recurring on most construction projects. As a consequence, time, cost and quality of construction, which are among the key project performance indicators (PPIs), have suffered poor performance in many construction project undertakings. While several studies have addressed these performance dependents parameters separately and collectively, the impact of political, environmental, social, technological, economical, and legal (PESTEL) related factors on the PPIs has however not been considered. The purpose of this study, therefore, is to identify PESTEL related factors, and further determine their impact on the PPIs in the South African construction industry. South African contractors, which are registered with the CIDB (Grades 5-9) were sampled and administered questionnaires to achieve the purpose of the study. The study determined that rework, poor planning, and inadequate training are most closely associated with poor performance of the PPIs. It is believed that addressing the areas of concern identified in this study would contribute to improved performance of the PPIs in South African construction, which would ultimately engender satisfaction of construction stakeholders.
