Reducing project execution time is an important aspect in today's construction industry. In practice, most construction projects are delivered behind schedule. This creates an incentive to find methods, processes and techniques to deal with elements which steal time and bottlenecks which cause delays. This paper address the magnitude, frequency and...

... 3 reflects the results of the divergences in time-thieves for both sectors. From this comparison, we see that the most common divergences are "Administration and bureaucracy", "Decision issues" and "Lack of capacity" with high occurence in public sector; whereas "Quality issues and errors" is the most important time-thief for the private sector, see figure 3. Figure 4 show the Bottlenecks in Private vs Public Projects. There are differences in "Decision issues", "Communication issues" and "Poor engineering process", they are of more importance to the private sector than the public sector; "Waiting", "Administration and bureaucracy" and "safety issues" are of more importance to the public sector. ...

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 o 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.

Chapter
Construction projects are often completed with large cost overruns, late schedules, and problems related to quality. The success rate of the current project in Semen Padang Co. cement plant construction industry is very low. The purpose of this study is to identify the delay factors that exist by revealing fundamental problems that affect project completion and determine the most influential CSF (Critical Success Factors) in improving the performance of cement plant construction projects from the perspective of the owner, contractor, and consultant. The research methodology uses Delphi interviews to identify CSF and the AHP (Analytical Hierarchy Process) method by pairwise comparisons to prioritize CSF rankings in the implementation of a cement plant construction project at Semen Padang Co. The results of the 3 (three) rounds of Delphi interview, the expert panel identified that the most dominant category of CSF affecting were project management, procedures, commitments, and implementation methods. While for factors include procedures and bureaucracy, plans and schedules used, project monitoring, commitment of all parties, accuracy of implementation methods, control mechanisms, placement of workers in accordance with experience, and the implementation of procurement systems. This was identified as the most important CSF to be taken into account when considering how to improve the performance of cement plant construction project. Future research will create a tool to control risk and evaluate the next cement plant construction projects based on CSF that we obtained in this study.
