TL;DR: In this paper, the authors investigated the time performance of road construction projects in the West Bank in Palestine to identify the causes of delay and their severity according to contractors and consultants through a questionnaire survey.
Abstract: The construction industry is one of the main sectors that provides important ingredients for the development of an economy. However, many projects experience extensive delays and thereby exceed initial time and cost estimates. Construction delay is considered to be one of the most recurring problems in the construction industry and it has an adverse effect on project success in terms of time, cost, quality, and safety. This study is conducted to investigate the time performance of road construction projects in the West Bank in Palestine to identify the causes of delay and their severity according to contractors and consultants through a questionnaire survey. The field survey included 34 contractors and 30 consultants. A total of 52 causes of delay were identified during the research. The survey concluded that the top five severe delay causes are political situation, segmentation of the West Bank and limited movement between areas, award project to lowest bid price, progress payment delay by owner, and shortage of equipment.

TL;DR: In this paper, the main characteristics of the construction industry compared to the manufacturing industry according to three levels: on-site production, one of a kind projects, and complexity were determined.
Abstract: The growing context of globalization permanently increases pressure on the construction companies to improve their performances in order to resist to the constraints of competitiveness in the international market. It has become ineluctable to look for introducing a new alternative capable of bringing creative improvement to the traditional production system. This paper will relate mainly to the most relevant management techniques in the construction industry, and more specifically, the lean construction concept. Initially, we will determine the main characteristics of the construction industry compared to the manufacturing industry according to three levels: on-site production, one of a kind projects, and complexity. Subsequently, we will focus our attention on the main sources of waste in the construction industry. Finally, a rigorous comparative study will be carried out to show the contribution of the lean construction tools in the promotion of traditional construction especially at the level of the following factors: Creating value and eliminating waste; Planning and mutual coordination; Site organization. Lean construction as Last Planner System (LPS), Value Stream Mapping (VSM), Just-in-Time philosophy, Visual management (VM) and 5S have shown a great ability to improve the traditional production system through waste reduction, encouraging people involvement, ensuring a pull flow production, and promotion of a continuous improvement philosophy.

TL;DR: In this article, the authors identified the common risks affecting time overrun in road construction projects in the West Bank in Palestine from contractors' viewpoint through a detailed literature review and a questionnaire survey was performed to rank the considered factors in terms of severity and frequency.
Abstract: The construction sector is one of the key economic sectors and is the main force motivating the Palestinian national economy. However, it suffers from number of problems that affect time, cost and quality performances. This study aims at identifying the common risks affecting time overrun in road construction projects in the West Bank in Palestine from contractors’ viewpoint. 45 factors that might cause delays of road construction projects were defined through a detailed literature review. A questionnaire survey was performed to rank the considered factors in terms of severity and frequency. The analysis of the survey indicated that the top risks affecting time overrun in road construction projects in Palestine are: financial status of the contractors, payments delay by the owner, political situation, segmentation of the West Bank, poor communication between construction parties, lack of equipment efficiency, and high competition in bids.

TL;DR: Mahamid et al. as mentioned in this paper identified the risk map for factors affecting cost overrun in building construction projects in the West Bank in Palestine from the consultants' perspective, and identified 41 factors are identified through literature review.
Abstract: This study aims at identifying the risk map for factors affecting cost overrun in building construction projects in the West Bank in Palestine from the consultants’ perspective. The field survey included 26 consultants. 41 factors are identified through literature review. The factors are divided into 5 groups. The analysis of the identified 41 factors indicates that 1 factor is located in the green zone, 14 factors are located in the yellow zone, and 26 factors are located in the red zone of the risk map. The results indicate that the top five affecting factors are: political situation, fluctuation of prices of materials, economic instability, currency exchange, and level of competitors. It is hoped that these findings will guide efforts to enhance the cost performance of construction industry. DOI 10.5592/otmcj.2013.2.5 Research paper Ibrahim Mahamid
