Abstract ▼ AI-Helper

While the idea of the existence of a set of key factors for success in planning, designing and construction of projects is not new, it remains one of the most important issues in the field of construction management. This is due to project success factors are inputs to project management practice which can lead directly or indirectly to project success. This study identifies the success factors which can be used for improving the highway projects performance in Egypt during the project pre-construction and construction phases. Through a detailed literature review 35 success factors are identified. Furthermore, the AHP is adopted to prioritize the studied factors through the application of questionnaire survey. The study establishes that implementing an effective quality control and assurance systems, allow sufficient time for feasibility studies, design, drawing and tender preparation, effective cost control system and frequency of project budget updates, preparing adequate designs and drawings and determining sufficient time to implement the desired scope of work are the most important success factors for enhancing the highway projects performance in Egypt.

제안 방법

• Section No. 2: Guideline for filling and establishing the relative importance weight: this part of the questionnaire illustrates how the participants can use the AHP in the bases of pairwise comparison to determine the importance weight of the suggested success factors in the questionnaire.
For the purpose of specifying the success factors which can be used for improving the performance of highway projects delivery and enhancing the management practice of such industry through the application of AHP technique, five steps have been designed to clearly illustrate the study methodology stages beginning from the review of the previous work regarding the theory of the AHP and factors of success, passing through structuring the hierarchy model and designing the questionnaire survey and ending with the analysis and discussions of the survey results. Figure 1 explains the research flowchart.
This has significantly reduced the pool size of the potential respondents. Second, some of the experienced practitioners contacted were reluctant to participate in the survey because of the commitment expected from them, noting that they have to make pairwise comparisons of 35 success-related factors.
The research method of this study is mainly based on a structured questionnaire survey in order to cover the requirements of the research objectives and achieve better results. The developed questionnaire has been designed in order to specify the relative importance weight of the suggested success factors to improve the highway projects performance through the application of AHP numerical rating.
This paper proposes the AHP approach as a tool to determine the priority of 35 success factors in order to determine the top critical success factors for improving the performance of highway construction projects in Egypt. The identified factors have been grouped under the following five headings: a) pre-project technical studies, b) contractual arrangements, c) interactive processes, d) monitoring and control and e) human related-factors.

성능/효과

According to the study results five success factors including implementing an effective quality control and assurance systems, allow sufficient time for feasibility studies, design, drawing and tender preparation, effective cost control system and frequency of project budget updates, preparing adequate designs and drawings and determining sufficient time to implement the desired scope of work have been ranked as the key factors for successful implementation of highway construction projects in Egypt .
This result is due to unrealistic contract time (duration) was identified by Aziz and Abdel-Hakam [25] as one of the most important factors contributing to the delay of the road projects in Egypt. Therefore, the results of the study highlighted that identifying reasonable time matching with the project requirements is an important success factor which greatly helps in reducing the delay of highway project in Egypt.

후속연구

Based on these findings, the study highlights that the pre-project technical studies phase is a key area for enhancing the performance of highway construction projects in Egypt. Therefore, more investigation on the aspects of this phase toward the project success would be valuable for further studies. Furthermore, the study suggests that further research can be carried out with a greater number of respondents.
