The Effects of Delays in Algerian Construction Projects: an Empirical Study

Salhi Roumeissa, Messaoudi Karima

Civil and Environmental Engineering Reports

2021

Vol. 31, no. 2

218--254

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.

A conception of tariffing passages flexibly by simultaneously facilitating easier controls of paying fares is suggested. Formulae of charging fares, which regard the factual passage by its elapsed time and passed distance, are stated. A scheme of executing fare payments and their control with using GPS navigators and controllers of time and distance is given.
