The Cost

As a project control technique concept that provides a quantitative measure of schedule and cost information, the earned value (EV) model can evaluate work progress by identifying the potential delay and the cost overruns in a project, which is useful for controlling projects. The construction industry in Korea does not put this concept into practice, however, because it is poorly understood and because the construction practices in Korea are different from those in other industrialized countries. Most important is the fact that almost all the construction projects in Korea are controlled in accordance with the budget breakdown structure (BBS), which is less detailed than the cost breakdown structure (CBS), while those in the USA are managed through schedule control on the basis of the work breakdown structure (WBS). This is because most of the construction projects in Korea are generally contracted at a fixed price. This being the case, once the contract is awarded, the clients are no longer concerned with the cost of the project. This current construction practice based on the BBS rather than on the WBS has brought forth a limitation in terms of the use of the existing EV model in the domestic market. In this study, the EV model, which is suitable for the domestic market, is demonstrated. An integrated model of the WBS and CBS is then developed based on the modified work-packaging model. Finally, the developed model is integrated into the project management system (PMS) to verify its suitability and efficiency.

Purpose – The purpose of this paper is to examine the need to develop building service standard method of measurement (BSSMM) that would provide a home ground advantage and a framework for managing the cost of building services by quantity surveyors. Design/methodology/approach – A review of previous research on the rules of measurement was carried out. This exercise provides the basis for questionnaire design which was administered to quantity surveyors in Malaysia construction industry. Findings – The results indicated the need to develop BSSMM. In total, 23 variables were identified as essential features of such standard method of measurement. These variables were grouped into three categories and a priority ranking of them was carried out. The analysis revealed a strong agreement among quantity surveyors on the priority ranking of the essential features of the BSSMM. Research limitations/implications – Although, the research would assist industry stakeholders in developing BSSMM that reflects local and international best practices, there is need to further investigate how the rules of the BSSMM could be aligned with construction industry classification systems. Practical implications – The availability of information and computer technology (ICT) tools has transformed the traditional practices in the industry and offered values to quantity surveyors, but if quantity surveyors’ tools cannot be consolidated and incorporated into emerging ICT applications, then QS collaboration will be difficult, and the requirements for electronic data exchange will be impractical. Therefore, this type of standard method of measurement will facilitate cross-referencing and coordination between BoQ and other documents such as drawings, specifications and tender produced by other project participants and thereby lay efficient foundation for effective collaboration of quantity surveyors in BIM model. In addition, the BSSMM will not only comply with local industry practices, it will also be internationally compatible. Originality/value – Adoption of a structured format based on BSSMM to present building services cost information is essential in view of the increase in the value and complexity of building services in modern buildings. However, there is need to enhance quantity surveyors’ knowledge in the technology and cost management of building services so as to ensure the reliability of cost advice provided to clients. This goal would be partly achieved through education and training of Quantity Surveyors/Cost Consultants in the interpretation and use of the rules of an SMM.

There is a philosophy in the construction industry to reduce the cost of a project by reducing construction waste and improving productivity. With lower expenses, lean construction emphasizes the cost of the project at a minimum cost. Globally, the philosophy has gained a wide range of popularity in the construction sector. The Lean Construction has helped practitioners with several tools and techniques to implement at different stages of a construction project. Following global trends, this study has investigated lean practices in Pakistan. With the potential advantages experienced by its implementation in Pakistan's construction projects and the level of implementation of various types of tools and techniques has been analyzed. To achieve the goal, the study had tried to capture construction projects in which four shareholders are being represented, which are clients, consultants, contractors and material suppliers. Overall 34 completed questionnaires were collected and then analyzed. The results of the analysis have indicated that pull approach, standard of work, time consuming, visualization tools, the integrated project delivery methods and the quality failure in safe limits are common lean techniques which are being implemented to the local construction industry. While there are major benefits of waste reduction, client satisfaction, better communication, visual control and proper task management to build appropriate work are the key benefits of lean construction.

Value Management (VM) and Value Engineering (VE) are techniques concerned with defining, maximizing and achieving “value for money”. It should be noted that VM is not about reducing the cost but about adding value and where necessary the cost can be added to achieve value. Despite its proven significance in securing maximum output from limited resources, this approach is not a common practice in Rwanda’s construction Industry. This study therefore defines VM and describes all the processes and techniques involved in it. The merits and demerits of VM process in construction projects are discussed in details and relevance of its uses is discussed and recommended in consideration of the scope and complexity of the projects as well as the risks involved. While the benefits of a value management review are often perceived in terms of improved quality and reduced cost, this report discusses the exercise as a functional mechanism to measure value, taking into account monetary and non-monetary benefits and thus demonstrating value for money. While the author has not been able to obtain relevant literature on VM practice in Rwanda, It can be deduced from the review of the related literature that most of the evaluation techniques conducted for construction projects in developing world have mostly relied on evaluation of project performance in terms of cost, quality, delivery and progress. Since project evaluation is carried out after the work has been undertaken, the output of the analysis will just give the client an indication or a good understanding of the project performance. Such evaluations only reveal the competence or incompetence of the project participants instead of providing value for money which is addressed by VM practice which is an ex-ante analysis that takes into consideration of all value parameters. The study used a quantitative survey method of research to obtain responses from professional practitioners in construction industry in Rwanda. The sample size of 115 were selected from members of professional practitioners in the construction industry out of which 106 members were responsive. Finally, it is concluded that VM approach is not used in construction industry in Rwanda and recommended that VM practice be adopted in construction industry in Rwanda as a mandatory requirement for conception of all construction projects with a budget of $20M and above

Despite broad improvements in construction management, claims still are an inseparable part of many con-struction projects. Due to huge cases of claim in construction industry, this study argues that claim management is a significant factor in construction projects success. In this study, the most possible causes of these emerging claims are identified and statistically ranked by Probability-Impact Matrix. Subsequently, by classifying claims in different cases, the most important ones are ranked in order to achieve a better understanding of claim management in each project. In this regard, a new index is defined, being able to be applied in a variety of projects with different time and cost values, to calculate the amount of possible claims in each project along with related ratios with respect to the cost and time of each claim. This study introduces a new model to predict the frequency of claims in construction projects. By using the proposed model, the rate of possible claims in each project can be obtained. This model is validated by applying it into fitting case studies in Iran construction industry.

The avoidance of failure in construction projects is not an easy task, which makes the failure of the construction project to achieve its objectives a major problem experienced by all countries in the world, especially Iraq. Where nearly two-thirds of the construction projects in the world have been suffered by significant problems as an increase in the cost of the project, delay in the specified duration for execution, and stopping the project. Therefore it is required to study and apply new methods for managing the construction project to ensure its success and achieve its objectives. The aim of this study is to study the Agile project management method and its impact on the construction project. In addition, to identify the values and principles of Agile project management, which can be applied in the Iraqi construction industry to be adopted it as a new method to manage the construction projects in Iraq. The researcher reviewed the relevant literature to define the method of Agile project management and its methods and impact on the construction project. Then, the researcher conducted a questionnaire survey of a sample of engineers' experts who work in four main parties in the construction project: (beneficiary, supervising, designer, and contractor). The results of this survey showed that it is possible to apply the four values of Agile project management for managing the Iraqi construction projects, and can apply eleven of the twelve principles of Agile project management for managing the Iraqi construction projects.

It plays an important part in the role in the economy as and in people’s survives over influencing and preserving the environment of the city-region’s constructed, and it is a rising sector. To provide an efficient performance and more development of the economic, there is emphases on optimizing the employees contribution to the goals and areas of the governments. The training significance as a management central part has long been documented by principal writers.This paper aim to find the impact of training in the construction industry and how the training is been underestimate lead in increase the cost by using the simulation technique system dynamic. The research methodology include designing of questionnaire that consist of three items , the first item include , general Training (Training Program), evaluation of on-the-job training and evaluation of training after establishing work and the second part include building the model using system dynamic to show the effect of training on the cost of construction. the results the authors made the following conclusions .The absence of training program has very strong effect as the absence of such program is caused by the finance absence , this is common problem with Iraqi construction industry. The most environment of the Iraqi industry is the absence of the finance from both owner and contractor as they ignore this part and consider unnecessary expenses and this will lead to unqualified engineering or worker in the wrong job .The absence of management mean that , usually the contractor and his staff are working without the supervise or represented from the owner side , which some time mean unskilled workers may be hired which lead to delay of the work and cost overruns .

Proper cost control and management is pivotal for the success of construction projects and companies alike. However, several of the systems in usage are fragmented, especially in regards to how cost data at the project, department and company levels are portrayed. This is particularly observed when companies carry a sizeable portfolio of projects in diverse and sometimes remote locations. This calls for establishing an integrated cost control and management system capable of addressing these deficiencies while portraying the cost status at various levels of the company’s chain of command. Paper introduces an information system (IS) developed for such purpose and which pools multiple actors in the company’s hierarchy. It has the potential to streamline the dataflow between the different departments and throughout the company’s chain of command. System’s functionality is based on the Object-Oriented (O-O) approach and the Unified Modelling Language (UML) known in System Analysis and Design (SAD) of computer-based IS.
