Review and assessment of the causes of deficiencies in design documents for large construction projects

PurposeDesign documents’ deficiencies (DDDs) are a major issue that plagues the construction industry in many countries. The purpose of this paper is to investigate the major causes of DDDs in a fast expanding economy, where errors can translate to an adverse impact on the economy. This paper aims to identify and assess the causes of DDDs for large construction projects from the consultants’ perspective.Design/methodology/approachIn total, 20 causes of DDDs were shortlisted through an extensive literature survey. In total, 37 consultants based in the Eastern Province of Saudi Arabia participated in the study. The respondents were requested to provide their opinion with respect to the relative importance of the identified causes. The result of their responses was then used to rank the causes.FindingsBased on their significance indices, the most significant causes of DDDs were “assigning design tasks to designers who lack work experience,” “team members’ communication skills,” “the level and quality of the design professional’s education,” “cross-disciplinary coordination,” “effective design team,” and “lack of knowledge transfer mechanism.”Practical implicationsRecommendations were provided to mitigate the issues of DDDs. It is envisioned that through a better understanding of the major causes of DDDs, design firms will be better positioned to recognize DDDs’ causes and establish appropriate measures for reducing their occurrence. The findings of this paper are beneficial to all project stakeholders, including design firms, clients, contractors, and end users.Originality/valueThis paper contributes to the literature by providing an assessment of the various causes of DDDs in the context of a rapidly expanding economy, where any inefficiency can lead to massive losses to the economy.
