AbstractPurpose -The paper seeks to identify the major factors causing delay in building construction projects in Malaysia. Design/methodology/approach -A questionnaire survey was used to carry out the study. The questionnaire consisted of 31 factors which were grouped into four major categories by responsibility -contractor factors, owner factors, consultant factors and external factors. The level of importance of the categories was measured and the relative importance of weights was ranked. Findings -The study finds that financial problems are the main factor and coordination problems are the second most important factor causing delay in construction projects in Malaysia. The results were analyzed to rank the causes of delay and further classify the types of delay.Research limitations/implications -The scope of this study is limited to building projects in the Klang Valley area, where major Malaysian cities such as Kuala Lumpur, Putrajaya, Petaling Jaya, Shah Alam and Seremban are located. The data for this study was gathered through a detailed questionnaire survey. Originality/value -Based on the analysis of the ranking and intensity of causes of delay, this paper suggests possible improvements that could be made in order to reduce delays in the construction industry.

PurposeHousing costs are very high in Yemen compared with Middle East countries, which caused a shortage of housing supply especially for low‐income groups. This paper aims to develop affordable housing design for people with low income and to examine their ability to afford houses in Sana'a, Yemen.Design/methodology/approachTwo different questionnaires were used to achieve the study objectives. The first one was to examine the requirements and needs of low‐income groups, while the second was to analyze the feedback of professionals in relevant housing authorities in Sana'a. An affordable house design methodology was used to design alternatives of low‐income housing in order to minimize cost and environmental impact while maximizing the social acceptability in housing projects.FindingsThe results show that the low‐income group can afford new houses in Sana'a in consideration of the following: constructing multi‐storey housing units such as apartment system through using the concrete frame structure and building the internal and external walls with concrete blocks with limited areas (65‐120) square meters.Originality/valueThe findings could be used to improve housing affordability through housing policies in Yemen in order to decrease the housing shortage particularly for the low‐income group.

The COVID-19 pandemic represents a type of force majeure that significantly and unexpectedly affected all human lifestyles. This study includes an integrative review of articles published across Scopus and Web of Science journals and compiled using the systematic review methodology based on the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) Statement and VOSreview (visualization of similarities) software by defining keywords that include “construction industry” and “force majeure” and “environmental risks” as a starting point. Moreover, the research years and the countries covered by this research were determined in a second stage. Finally, the abstracts of selected studies were reviewed in order to extract factors similar to the pandemic conditions of COVID-19 along with the brief results of the research. Out of 6384 publications identified and 56 publications reporting, 20 studies fulfilled the inclusion criteria with full text. Based on our findings, there has been a continuous growth of publications on construction risk and environmental research since 2010. Malaysia had the greatest contribution to the research topic of the countries covered by the study, followed by Egypt. The Engineering, Construction and Architectural Management journal published the greatest number of publications related to the research topic. In this review, the most important previous studies are classified according to their handling of force majeure and environmental risks and the most important factors mentioned in these studies are identified. In addition, recommendations are made for dealing with the COVID-19 pandemic and for mitigating its effects on the construction industry in the Arab world and Malaysia. The results of this review will benefit researchers and construction companies alike in furthering research on reducing the risks of COVID-19 to construction projects and avoiding the significant economic loss that results from stopping these projects.

Purpose -The purpose of this paper is to identify the factors that cause housing shortage for lowincome groups in Yemen and recommend some solutions to alleviate the problem. Design/methodology/approach -A questionnaire survey has been used as the tool to carry out this study. The first part of the questionnaire consisted of three groups namely: economic, administrative, and legal factors. The second part consists of suggestions on housing supply, construction methods, and materials used for low-cost housing in Yemen. The level of importance of the categories was measured and the relative importance of weightage was ranked. Findings -The results show that the most important economic factors causing housing shortage were poor handling of available economic resources and shortage of economic resources. The most important administrative factors causing housing shortage were lack of organization and synchronization and not conducting studies on housing. The most important legal factor causing housing shortage was lack of legalization of housing. Originality/value -The findings could be used to improve housing policies and strategy in Yemen in order to decrease the housing shortage, particularly for the low-income group.
