The traditional method of project cost control management by objectives based, is a passive expost control, and system dynamics model through the establishment of a strategiclevel description of the project, emphasizing the active control of project costs, focused on the complexity of factors that are difficult to accurately quantify analysis is an important complement to traditional methods. Construction phase of the project cost control of construction project management is one of the main construction phase of the construction project in accordance with established cost control feedback effect diagram, analyze the main factors affecting cost control, qualitative analysis of the impact of the construction phase of the project cost control various factors and cost control effect brought. Proven system dynamics approach applied in the construction phase of the project feasibility.

Themain content of the construction project cost management including costforecast, cost plan, cost control. Do cost forecast, cost control goal set,must be ahead of the labor, material, cost forecasting, construction scheme ofchange of the cost forecast and the prediction of auxiliary construction cost.Cost control should follow the principle of conservation and comprehensivecontrol, there are some effective ways to realize the cost control, forexample, take organizational measures to control the project cost, take technicalmeasures to control the project cost, to take economic measures to control theproject cost, strengthen quality management and control of rework rate, etc.

Purpose – An extensive search of the literature revealed a dearth of research on the demotivational factors affecting the performance and productivity level of site-based construction project managers. Following the announcement of awarding the FIFA 2022 World Cup hosting rights to the State of Qatar, the State is pledging to spend tens of Billions of Dollars on hundreds of new construction projects. Therefore, the purpose of this paper is to identify, explore, and rank the relative importance of the demotivational factors influencing the productivity of the State's construction management force. Design/methodology/approach – A structured questionnaire survey comprising 38 potential demotivational factors, which were shortlisted based on relevant previous studies on the impact of motivation on construction productivity, and numerous interviews with local industry professionals, was distributed to a relatively large sample of site-resident project managers. Using the “Relative Importance Index” technique, the influence ranks of the factors explored were determined. Findings – The results obtained reveal the following as the prominent demotivational factors influencing the productivity of construction project managers: lack of financial incentive schemes; slow decision-making process by owners; remuneration scale; delay in responding to Requests For Information (RFI); shortage of skilled labour force; shortage of materials; clarity and completeness of technical specifications; frequent changing orders during execution; drawings quality level; and rework. Research limitations/implications – It is clear, based on the outcomes, that the cultural background of individuals, and the prevalent practices within the environment in which they operate, are two critical factors in determining their motivation drivers. Hence, it is prudent to explore the dominant culture and values of the management workforce, in addition to the characteristics of the working environment, before trying to apply relevant motivational theories, or even implement new management strategies. Practical implications – The results demonstrate that, within the geographical setting and cultural aspects of the sample surveyed, “tributes” and “pecuniary” may be interpreted to have the largest effect on the productivity of construction project managers. Originality/value – The findings not only contribute to the overall body of knowledge related to the effect of the motivation phenomenon on the productivity of the construction operation, but can also be used to provide industry practitioners with guidance for focusing, acting upon, and controlling the significant demotivational factors affecting the efficiency of the construction project management force practicing in State.

The main goal of this research is to ensure the important of engineering software in the construction industry in Kingdome of Bahrain. A self-administered questionnaire was done via E mail .The research investigated the impact of engineering software toward three factors of the success project scope, cost, and time. The results show that there is positive impact when we are using engineering software on construction project management. The primavera project manager software is the major software is using in construction companies for planning and controls the project; primavera project planning p3 is the second software and the third software is MS project. The research concluded that the engineering software positively impact on project success and increase its performance.
