Abstract
Abstract Delay is one of the most recurrent problems in the construction industry. It is the cause of major negative consequences on construction projects and it can be the main reason for project failures. Still, there is a need for studies focusing on causes of these delays. The objective of this article is to determine the factors with greatest influence on the backlog of real estate developments, improving the collective list of causes of delays in construction projects. A list of 24 probable causes was assembled and submitted as a survey for 47 professionals in administrative rolls from the building construction sector, more precisely, from private companies. The results were processed utilizing the Relative Importance Index (RII) ranking approach. The outcome shows that the most important delay causes are: rework, poor labor productivity, lack of qualified labor, unqualified labor, and project changes. The results also indicate that there are significant differences of opinion between the professionals of distinct hierarchy positions. The results obtained indicate that there is a transition between the opinions of professionals in different roles regarding the importance of influential factors in the delay of works, according to the managerial level of each group.

Summary
The compliance with deadlines in the construction industry is essential for the success of a new structure, from the point of view of the client or regarding the financial expectations of the constructors.

The compliance with deadlines in the construction industry is essential for the success of a new structure, from the point of view of the client or regarding the financial expectations of the constructors. This topic is considered one of the main pillars in accomplishing good results in the construction sector. To plan and to control the deadlines should be a priority, when it comes to the construction management of a new development. Companies employ many methods to control the construction time, the complexity involved poses challenges in guaranteeing appropriate results. Delays in a construction project may foment other problems for the parts involved. Delays in a construction project may foment other problems for the parts involved. Mydin et al (2014) indicated the five most relevant issues, in order of importance: over-budgeting; conflicts of opinions; renegotiations; judicial lawsuits and complete abandonment of the construction
