Abstract
Construction delays are considered a common worldwide problem. Previous studies have investigated construction delay factors from the perspectives of different project stakeholders. However, a thorough analysis of such delays on different types of construction projects in different geographies is still lacking, precisely the effect of employers’ delays in traditional and building information modeling (BIM)-enabled projects. This research proposes a research framework to address potential employer-caused delay factors in traditional and BIM-enabled projects. A cross-sectional literature search was carried out to review construction delay factors and employer-caused delay factors in traditional and BIM-enabled projects. The study found that: (a) a research gap exists in traditional construction delay studies in specific continents and project types as well as in BIM-enabled project studies, (b) delay aspects have not been addressed or have been partially addressed in previous studies, and (c) a relationship model between employer-caused delay factors and success factors can be developed by studying the effects of BIM barriers and implementation strategies. This paper is the first to present a comprehensive review on delay factors and tender a novel framework to address employer-caused delay factors in both traditional and BIM-enabled projects.

Summary
Construction delay is a significant problem for the construction industry. construction delay factors and their causes have received considerable attention from both academia and industry. Khair et al [5] studied construction delays in Sudanese road projects and proposed a management framework to address and reduce the delays. Despite the growing importance of addressing construction delay while taking all associated aspects into account, it is still considered that construction delay aspects, employer-caused delay factors, and delay characteristics have been discussed previously without carrying out an indepth review that can help in filling the research gaps in previous studies. E research gaps are as follows: very few or no studies have been conducted on some type of projects, sufficient construction delay studies have not been conducted in some continents, and an appropriate framework is not available to completely address construction delay. BIM implementation barriers should be considered to study their influence on the success factors for addressing employer-caused delay factors in BIM-enabled projects
