Abstract:
Abstract: Many are the problems that may arise through the different phases of any construction project; the “Design” is the phase considered as the roadmap to achieve the project expectation. However, design error appears to be found in all types of construction projects and can significantly degrade the project performance by generating reworks necessitating additional time, cost and resource expenditure. This paper conducts a study of the impacts of the design errors on construction project performance typically applicable to the Lebanese construction sector where majority of design firms omit design audits, reviews and verifications to maximize their fees and profits; the objective is to identify the causal factors of design errors in construction projects, and assess them with their derived relative weights in terms of project performance impact. Ranking of causes depending on respondents’ opinion and agreement among raters are conducted.
