Abstract
This paper examines the effects of delays in the Algerian construction industry in order to identify the various critical aspects of the causes for improving the economy in the construction sector. A questionnaire survey was conducted to assess the perceptions of all players in the construction industry, which led to the identification of the most significant impacts of delays. The results show that ten main effects of delays in the construction sector are at the origin of many constraints that have a negative impact on the economy of the country. Further, the factor analysis technique was performed to categorize the identified effects into main groups, and it yielded 5 groups (factors). As an important contribution, the relationship between these groups was tested using the SMART-PLS, and a structural model has been developed. Also, a comparative study with other previous works on the most critical effect of delays in construction projects has been conducted and the results show that the main effects of delays in the construction industry are at the root of many constraints in reaching and achieving the objectives.
Highlights
The construction industry is one of the major sectors that contribute tangibly to the economic growth of countries [11, 42, 4]
In 2002, Aibinu and Jagboro[3] carried out a study for identifying and evaluating the effects of delay in the Nigerian construction project, Aibinu and Jagboro[3] emphasized that time and cost overruns, litigation, arbitration, and total abandonment were the main effects of delay in the Nigerian construction project
The findings show that poor site management, improper planning, and lack of experience were the three prominent factors of delay, while the most significant effects were time overrun cost overrun, disputes, arbitration, litigation, and total abandonment
Summary
The construction industry is one of the major sectors that contribute tangibly to the economic growth of countries [11, 42, 4]. For the last two decades, extensive research on time delay has been carried out over the world The majority of these studies are focusing on causative factors. Abdullah[1] developed a questionnaire survey to determine the main causes and effects of delay in large MARA (Majlis Amanah Rakyat) construction projects in Malaysia, and they found similar results to the findings of Sambasivan and Soon [39]. The findings show that the highly ranked causes were design change, and problems of communication, while, the most significant effects were: times and cost overruns, negative social impact, disputes, and idling resources, Owalabi et al [35] evaluated 15 causes and 8 effects of delays in Nigeria using the mean index score (MIS). Sunjka and Jacob [41] examined 38 causes and 8 effects of project delays in the Niger Delta region
