TL;DR: In this article, a questionnaire survey was undertaken of project managers working on high-rise construction projects in two Indonesian cities: Jakarta and Yogyakarta, and the results reflect construction management problems common to developing countries.
Abstract: Many variables have an impact upon construction time and cost overruns in Indonesia. A questionnaire survey was undertaken of project managers working on high-rise construction projects in two Indonesian cities: Jakarta and Yogyakarta. The variables identified were ranked according to their perceived importance and frequencies of occurrence. Inflationary increases in material cost, inaccurate material estimating and project complexity are the main causes of cost overruns. The predominant causes of delay are design changes, poor labour productivity and inadequate planning. Using factor analysis techniques, delay and cost overrun variables were grouped into factors, and their relationships analysed. Although Indonesia specific, the results reflect construction management problems common to developing countries.

TL;DR: In this paper, an activity sampling technique was used on seven construction sites in Nigeria to determine how the working day was being utilised by craftsmen in bricklaying, joinery and steel fixing trades.

TL;DR: In this article, the authors investigated the problems influencing craftworkers' productivity on 27 medium and high-rise building sites surveyed in Indonesia and identified five specific productivity problems, i.e., lack of materials, rework, absenteeism, lack of equipment and tools and gang interference.

TL;DR: In this paper, the authors used the relative index ranking technique to identify the five highest-ranking problems in Iran: Materials shortage, weather and site conditions, equipment breakdown, drawing deficiencies/change orders, and lack of proper tools and equipment.
Abstract: Construction productivity is rarely analysed in Iran. If productivity is to improve, current weaknesses must be identified. To this end data were collected through a structured questionnaire survey. By utilizing the relative index ranking technique, the identified problems were prioritized for detailed analysis and discussion. Results indicate that the five highest-ranking problems are: Materials shortage, weather and site conditions, equipment breakdown, drawing deficiencies/change orders, and lack of proper tools and equipment. Devastating war with neighbouring Iraq has led to a boom in construction activities leading to shortages of construction materials. The casual employment of the majority of construction operatives and poor managerial skills are the significant contributors to low productivity on Iranian construction sites.

TL;DR: In this article, a study conducted with the aim of identifying factors affecting motivation of Iranian construction operatives was reported, which indicated that the five most important motivation factors of Iranian Construction operatives are, in descending order: "fairness of pay", "incentive and financial rewards", "on-time payment", "good working facilities", and "dsafetyrd".

TL;DR: The Human Side of Enterprise as mentioned in this paper is one of the most widely used management literature and has been widely used in business schools, industrial relations schools, psychology departments, and professional development seminars for over four decades.
Abstract: \"What are your assumptions (implicit as well as explicit) about the most effective way to manage people?\" So began Douglas McGregor in this 1960 management classic. It was a seemingly simple question he asked, yet it led to a fundamental revolution in management. Today, with the rise of the global economy, the information revolution, and the growth of knowledge-driven work, McGregor's simple but provocative question continues to resonate-perhaps more powerfully than ever before. Heralded as one of the most important pieces of management literature ever written, a touchstone for scholars and a handbook for practitioners, The Human Side of Enterprise continues to receive the highest accolades nearly half a century after its initial publication. Influencing such major management gurus such as Peter Drucker and Warren Bennis, McGregor's revolutionary Theory Y-which contends that individuals are self-motivated and self-directed-and Theory X-in which employees must be commanded and controlled-has been widely taught in business schools, industrial relations schools, psychology departments, and professional development seminars for over four decades. In this special annotated edition of the worldwide management classic, Joel Cutcher-Gershenfeld, Senior Research Scientist in MIT's Sloan School of Management and Engineering Systems Division, shows us how today's leaders have successfully incorporated McGregor's methods into modern management styles and practices. The added quotes and commentary bring the content right into today's debates and business models. Now more than ever, the timeless wisdom of Douglas McGregor can light the path towards a management style that nurtures leadership capability, creates effective teams, ensures internal alignment, achieves high performance, and cultivates an authentic, value-driven workplace--lessons we all need to learn as we make our way in this brave new world of the 21st century.

TL;DR: Wang et al. as discussed by the authors analyzed the key risks in construction projects in China and developed strategies to manage them from a joint perspective of project stakeholders and life cycle and concluded that clients, designers and government bodies should take the responsibility to manage their relevant risks and work cooperatively from the feasibility phase onwards to address potential risks in time.

TL;DR: In this article, the authors developed a conceptual framework on critical success factors (CSFs) and identified five major groups of independent variables, namely project related factors, project procedures, project management actions, human-related factors, and external environment, as crucial to project success.
Abstract: Different researchers have tried to determine the factors for a successful project for a long time. Lists of variables have been abounded in the literature, however, no general agreement can be made. The aim of this paper is to develop a conceptual framework on critical success factors (CSFs). Seven major journals in the construction field are chosen to review the previous works on project success. Five major groups of independent variables, namely project-related factors, project procedures, project management actions, human-related factors, and external environment are identified as crucial to project success. Further study on the key performance indicators (KPIs) is needed to identify the causal relationships between CSFs and KPIs. The causal relationships, once identified, will be a useful piece of information to implement a project successfully.
