This study investigates Omani O&G project’s performance and analyzes the most common time and cost overrun causes. In addition, the effects of delays are examined further along with the key enablers for efficient project delivery. This study adopts a mix method of research to improve the level of credibility of the study. A sample of 160 respondents is employed following both quantitative and qualitative method where a well-structured questionnaire was used for interviews with the concerned personnel. Following the quantitative method, this study revealed that 8% of the respondents, says the projects have completed ON time where the response rate was 80%. Besides, the qualitative part backed up this data as most of them have experienced delay of 3 months to 2 years of delay. For cost, 3% of the respondents have experienced projects finishing ON budget and the interviewees have expressed that the average cost overrun is between 10%-30%. In terms of time overrun group factors, the top group time-overrun factors among all the three parties are management factors, where it is ranked first by all stakeholders. The sub-group factor that affects more is the project planning and control. Poor understanding of scope of work during tendering factor is ranked first with main contractor and second with both the client and engineering firms. This factor is most factors that has similar ranking between all. As matter of fact is the only factor that exists between in the top 10 among all stakeholders. This study claimed that understanding the scope of work of the project properly and giving its time to be grasped by the contractors is one of the key solutions to tackle the top factor of this research. Also, the SOW must be detailed as possible to avoid any conflict between the parties, one of the recommended details to have WBS included.

Construction projects facing cost overrun is a common problem in developing countries, including Pakistan. This research paper identifies the major cost overrun factors faced by construction projects in Pakistan and also provides recommendations to reduce the cost overrun. To main objectives of this research is to identify the critical cost overrun factors and its controlling measures. To attain objectives, the first in-depth literature review was conducted, which helped to identify 33 common cost overrun factors. Secondly, a structured questionnaire was established among stakeholders of the construction sector to share feedback about the critical cost overrun factors. Results showed that stakeholders of construction projects (consultant, contractor, and client) have a different perception of cost overrun. After identification of major cost overrun factors, interviews were carried among mostly experienced stakeholders for mitigation and control measures. This research delivers a better understanding of major cost overrun factors. Also, it provides recommendations to stakeholders of construction projects as well as other professionals of Pakistan to control cost overrun.

The Impact

Cost overrun in construction projects is a common phenomenon in Iraq. This might occur due to diversity of factors. This study aims to identify the factors influencing construction projects cost that are potentially controllable by main contractors. A field study through a questionnaire survey was directed to a sample of related Iraqi professional engineers from general contracting companies at both public and private sectors. Their opinions on the impact and frequency of each factor were investigated. The questionnaire offered (59) factors classified in (8) categories namely; legislations, financial and economic, design, contractual, site management, material, labor and equipment. The factors were ranked according to the highest Relative Importance Index (RII). The study revealed (10) major factors that are potentially controllable by main contractors namely; labor productivity, sub-contractors and suppliers performance, equipment productivity, site organization and distribution of equipment, experience and training of project managers, scheduling and control techniques, planning for materials supply, planning for equipment supply, materials delivery and planning for skilled labor recruitment. Recommendations to aid contractors and owners in early identification of these factors are also included in this study.

UAE construction industry frequently faces poor cost performance which commonly known as cost overrun problem. This problem is resulted from several factors and it is important to identify these cost overrun factors in order to avoid and minimize it. Hence, this paper focused on determined the relevancy of factors affecting cost performance in construction projects of UAE. Through a review of past research works conducted globally, 27 factors of cost overrun were listed and used for developing a structured questionnaire. A survey was conducted with 33 practitioners from client, consultant and contractors organizations involved in handling construction projects in UAE. The respondents were requested to state their perception regarding the relevancy of each of the factors that was perceived in context with cost overrun issue using 5-points Likert scale. The responses were analysed using average index method and the results found that all the 27 factors are relevant with construction industry of UAE in causing cost overrun. These factors can be used for further investigation to uncover critical problems of cost overrun.

The main objective of this research study is to investigate the extent to which knowledge management is used within the mining industry. Knowledge management includes the identification and examination of available and required knowledge and the subsequent planning and control of actions to develop knowledge assets to accomplish organizational objectives. A structured questionnaire is used for the study. A total of 300 mines were randomly selected from a research population of mining organizations in South Africa, Africa and globally. The respondents were all part of senior management. A response rate of 64% was achieved. A significant number of respondents indicates that there is no transfer of knowledge about the best practices within their organizations. Some of the participants indicate that their organizations do not have the required technical infrastructure to enable knowledge sharing whilst some agree that the culture in their organizations is not conducive to the sharing of knowledge. A statistically and practically significant positive relationship with a large effect is found between the construct of knowledge management and perceived business performance. The mining organizations in Africa are ranked the lowest in terms of applications of knowledge management principles
