Impediments to the Construction Industry Development of Yemen

2005

The construction industry in Yemen and other developing countries are now coming under more pressure to meet future demand for sustainable and economical development and this will necessitate changes in cultures and the formulation of appropriate policies and strategies to spearhead these changes. This paper presents a census of expert opinion, using a Delphi questionnaire methodology to rank a set of selected strategies and policies required for realizing economic sustainability in the construction industry. The proposed policies and strategies are derived from various international reports such as Agenda 21 for Sustainable Development. The proposed policies and strategies are specifically chosen as they are considered to be compatible with the Yemen construction industry and are also seen to more readily integrate with cultural aspects of Yemen, particularly in focusing on the hardships of its existing local needs, capabilities, priorities, and the willingness for development. The paper proposes, ranks and discusses the most needed policies and strategies to develop a suitable framework able to sustain the construction economy in Yemen. Within the course of this investigation it was intended to bring awareness to professional groups and experts about sustainable development.

This purpose of this study is to validate the important risk factors influencing the construction projects in a developing country of Yemen by using experts’ evaluations and literature review. These factors influence the project’s quality, time and cost. The semi-structured interviews were employed through online means using thirteen experts to achieve the set objective. Depending on the expert’s overviews, out of 56 considered factors, 42 factors were assigned as the most related risk factors influencing the construction projects in Yemen. The obtained outcomes from this study can serve as the risk factors for building blocks in establishing a conceptual model to manage risks of the construction projects in Yemen.

Construction affordability is identified in Agenda 21 for Developing Countries as one of the main issues associated with sustainable construction and sustainable development. Despite international awareness of sustainable construction, the cost rates for construction activities and resources have been continuously increasing. Due to these increases the approaches to be used to achieve sustainable construction through efficient and affordable techniques can be difficult to determine. This paper will examine the behaviour of the main construction costs and building rates, concurrently with socioeconomic behaviour, for the purpose of identifying some of the deficits in construction activities in developing countries, such as Yemen. This is achieved by examining past and current trends in the construction industry over the last two decades.

Construction projects in Yemen, like other developing countries, are dramatically experiencing a highly risk prone, due to their complex and dynamic environments. Thus, such nature is creating an atmosphere of high uncertainty and risks. This consequently leads to both project time and cost overruns. In this paper, a study is carried out to identify and assess the critical risk factors that are influencing time and cost of construction projects in Yemen. Through a comprehensive review for related literatures, 54 common risk factors are identified and categorized into ten groups. The study is further guided by interview sessions as well as a questionnaire survey to professionals and practitioners of construction projects in Yemen, in order to collect the required data. Analyzing the data is statistically accomplished using SPSS software. Results show a significant frequency of time and cost overruns of construction projects in Yemen. Delay in delivery of materials to site and Political instability are located at the top-ranked risk factors that cause projects delay. While, on the other side, the risk factors of Increase of Inflation rates and Fluctuations in the material's prices have the most significant impact on project's budget. However, the research introduces some risk factors, which have the same degree of impact on both time and cost. Moreover, results demonstrate that 47 % of the total projects faced time overrun while 40 % of the total projects faced cost overrun in Yemen.

The aim of this paper is to examine, comprehensively, the factors which affect the performance and development of the construction industry (CI) and the building materials industry (BMI) in developing countries (DCs) with special focus on Sudan. This paper investigates the perception of the Sudanese construction industry (SCI) and the Sudanese building materials industry (SBMI) stakeholders towards the importance of factors which negatively influence the performance of both industries. It examines the interrelationship between factors influencing the performance of the SCI and the SBMI. The collected data is derived from a questionnaire which was circulated to different stakeholders of the SCI including consultants, contractors, real estate investors, clients, researchers, academicians, materials manufacturers and suppliers, financial institutions and non-governmental organizations (NGOs). The results indicate that the socioeconomic and political factors are of great importance to the performance of both industries. Therefore, the paper recommends that the government should lay the ground for the development of the construction sector through strategic planning and policy formulation. It also recommends establishing a central agency (Construction Industry Development Board) to be responsible for the development of the industry.

Large construction projects in Yemen face many impediments and challenges to be completed successfully. This article presents an investigative cases study of three mega construction projects which are considered failed to achieve their assigned plans and objectives. An exploratory interview was implied in this study via telephone to three construction experts who involved directly in these mega projects at the managerial level. Semi-structured questions based on literature were designed as guide for the interview where the scope was mainly on causes of the mega projects failure. Outcomes from this study found that Yemen construction industry lacks of proper accrediting system to accredit construction stakeholders (contactors, consultant); improper planning for cost and time, lack of effective communication and coordination platforms and lack of advanced technology which are considered amongst the crucial challenges faced by industry. Hence, Yemeni construction industry is in dire needs of an effective platforms and system to administer project communication, information and coordination. Findings of this study can be useful for Yemeni construction community to understand causes of the failure and suggestions provided by experts are also very helpful in creating better quality works.

The construction industry in Uganda has over the past decade experienced a boom in activities. This is as a result of the rapid population growth that is triggering the demand for housing and infrastructure. Despite the surge in activities, the industry continues to exhibit low levels of technology utilisation, contractors have continued to employ old methods of construction culminating in long construction cycles, increased costs of construction and environmental degradation. The research was conducted to take the form of a quantitative research study. The research sought the views of various respondents towards the factors hindering development of the construction industry in Uganda. Key findings revealed that the level of development in the construction industry is still very low, and the major factors contributing to this in order of priority as per the findings from the research are financial capacity, lack of research and development, economics and costs, corruption, political...

Yemen is one developing country in the Middle East, which suffers from housing shortage. Unprecedented rapid urban growth coupled with lack of infrastructure has led to the problem of housing shortage for the low-income group in Sana'a, the capital city of Yemen. Consequently, informal housing patterns are observed clearly in some sectors of the city. The low-income group has built this kind of housing urgently and in some cases immediately as the final and only solution, yielding serious implications on the quality and safety of the houses. The overriding objective of this study was to identify the significant factors, which have influenced the construction cost of housing in Sana'a to resolve the housing shortage for the low-income group. Specific objectives have included determining the factors causing housing shortage for low-income group in Sana'a; justifying the significant factors influencing the cost of low-cost housing; and recommending to relevant authorities in Yemen to improve housing policies to mitigate the housing shortage in Sana'a. An important contribution of this study is the analysis

Construction in Oman is an important sector that contributes greatly to the country’s economic growth. Recently, the construction projects in Oman have been delayed which has led to delays in the projects’ completion and sometimes to their failure. This study aims to examine the critical factors affecting the success of construction projects in Oman. The extent to which factors related to project parties affect this success was assessed. A quantitative approach based on systematic literature review and questionnaire survey technique was used. The factors were identified and classified into six main categories, namely, time; finance; project designing, planning and scheduling; quality; project progress and development; and environment and nature. The factors are also classified as client-, consultant-, contractor- and external-related factors. This study was conducted by distributing questionnaires to people who experienced working in the public and private construction sectors in Om...

Construction projects are inherently exposed to various risk and uncertainties. Numerous studies have identified risk factors in construction projects in developed and developing countries. Yemen has witnessed revolutions and wars during the past six years, which affected the construction sector among other sectors. The purpose of this paper is to determine risk factors during the unrest period in Yemen. A list of 72 risk variables was developed based on the literature review followed by a questionnaire survey to determine relevant variables and factors. The results of this study explored new components of risk variables, namely environmental, resource-related, technical, conflict, design-related, profit-related, liquidity and revolution, and change. In addition, the results indicated critical risks affecting construction projects and main strategies to respond to them. The results of this paper provide an essential step for managing risks, so project managers and other professionals can ensure good project performance. However, further study is required to investigate the effectiveness of risk response strategies proposed in this paper.
