This research project constitutes an attempt to improve the construction industry's change management process by introducing the Form 'X' Control Mechanism as the means of establishing an effective method of project control. The traditional practice in the construction industry of appointing the principal designer as team leader has been challenged with the main criticisms on the traditional practice being his, or her, lack of managerial ability and his, or her, failure to control the financial aspects of the project. The traditional approach has remained essentially unchanged for more than a century but it has become increasingly questioned as the primary means of design management. One aim of the research, therefore, was to ascertain whether the traditional practices currently is use in the United Kingdom and Hong Kong could be improved upon. The research began by examining basic systems and project management concepts and noted the development of project management systems and structures for the construction industry. This was illustrated by reference to a number of articles and it was possible to argue that the industry lacked a comprehensive change control methodology. The research also provided evidence that the mechanisms used to exercise control in manufacturing industries could not be used to exercise control over construction projects. This is due, in the main, to the relatively short duration of construction projects and the transient nature of project personnel. Having examined the difficulties, it has been possible to devise a control methodology which couples communication and control and this mechanism has been adapted to fit existing industry practices. Using this criterion it was possible to formulate a control procedure which obviates the difficulties which can arise using the traditional approach to change management. The Form 'X' mechanism requires the design team to quantify, in financial and programme terms, the effect of design or construction changes, and to obtain the client's specific authority prior to revising the works. In doing so the Project Manager is able to determine the magnitude of all changes in terms of time, money and quality. The system is sufficiently flexible to enable it to be used world-wide, on projects of varying contract values and duration, and it requires only minor modifications to meet the provisions of the standard building and civil engineering conditions of contract. A variant of the proposed methodology was introduced by Hong Kong's Mass Transit Railway Corporation and utilised on a number of projects. These contracts were examined in detail, as were a number of Mass Transit Railway Corporation contracts which utilised the traditional approach to project control. The analysis showed that all of the projects on which the Form 'X' system had been used had been completed close to their original contract value whilst a number of the projects which did not use the control methodology suffered from significant cost over-runs. It was concluded that the Form 'X' methodology successfully eradicates many of the control problems which permeate the traditional approach to change management embodied in the standard conditions of contract for building and civil engineering works. The Form 'X' control approach was also shown to be popular with the Hong Kong Mass Transit Railway Corporation's senior management team, as well as with the consultants employed in the construction of the railway. The conclusion of the research project is that the Form 'X' procedure is a highly successful change control methodology which could be used throughout the world on a wide variety of building and civil engineering projects.

This thesis examines costing systems adopted within Turkish and British paper industries and assesses the appropriateness of Activity Based Costing for this area. It includes two case studies, one of which was performed in a Turkish paper mill and the other in a British one, that describe and examine product costing methods adopted and cost drivers employed within the costing system. The study also contains the results of two questionnaire surveys, one of which was applied to the Turkish and the other to British paper industry. All paper mills in the two industries were included within the survey response rates of which are 65.2% and 40.25% of the Turkish and British mills respectively. The questionnaire survey was designed to shed light into the costing practices adopted within the two paper industries. The results of the case studies and surveys indicated that the existing costing methods adopted and cost drivers employed within the two industries were appropriate for their manufacturing environments. Almost all the mills surveyed were found using traditional methods for their product costing and decision-making needs. Although ABC was implemented by a small number of factories, it was found inappropriate by two mills (one Turkish and one British) and hence abandoned. Different production processes and product types were identified as the main reason of this unsuitability. Also, most non-volume-related activities that may produce cost distortion in electronic and machinery-parts industries either do not exist or the effect of which over products is not important in the paper industry. Machine hour and production tonne cost drivers were found as being employed generally in both paper industries studied.

Construction clients, particularly those with little or no previous experience of building projects, depend on the advice given by building professionals during the early design stages. Accurate advice regarding the estimated cost of the proposed project is fundamental, as this will determine the financial feasibility of the proposed project. All professionals give advice based on the information available to them at the time. Therefore, cost advisors need to have an accurate appreciation of the client's requirements from the building, before they can estimate the likely cost. Inexperienced building clients may have difficulty expressing their requirements, or understanding detailed technical information prepared by building professionals. This thesis addresses the problem of poor communication between clients and building professionals leading to mis-interpretation of mechanical and electrical (M&E) services requirements and inaccurate cost estimates. The research hypothesised that the cost of M&E services was related to the form and function of the building, and the quality of the M&E services required by the building client. It was believed that the required "quality" of the M&E services had a major cost implication, and therefore the production of an accurate cost estimate depended on an accurate understanding of the quality of M&E services required by the building client. The research examined existing method, of early cost estimating for M&E services, to establish how early cost estimates are prepared, and what type of information is considered. Detailed statistical analysis work was undertaken to examine relationships between various building form, parameters and M&E services costs, for buildings of different functions. M&E services quality was considered in relation to the function, performed by different systems, using the value engineering technique of function analyis and customer oriented function analysis system technique (FAST) diagrams method for improving early design stage communications developed, to improve the interpretation of M&E services quality requirements and lead to more accurate cost estimates. The method involved the introduction of a briefing workshop to consider functional requirements from the building, possible M&E services solutions, and interfaces between building structure and fabric and the M&E services. The proposed method was evaluated in the field. It was found to be a valid method of improving early design stage communications between clients and building professionals, that could lead to improved early cost advice for M&E services.

Large bodies of empirical evidence show that policies and practices that support failure in schools does little to improve student outcomes, yet course failure remains widespread in secondary schools. Further, there is a growing body of evidence indicating these policies and practices are costly in fiscal terms. This study builds on this body of evidence to ask the question: how much money does course failure in secondary schools cost the Ontario public education system annually? Borrowing from Levin & McEwan’s resource cost modelling approach, the study calculates the volume of course failure across all secondary schools in the province and establishes estimates of the annual cost of secondary course failure taking into account some factors known to be systematically related. This work aims to better understand the costs of providing public secondary school education in order to make more effective use of resources. In the 2008–09 school year 7.9% of course registrations in Ontario secondary schools resulted in failure. Fail rates are greater for students who receive special services and vary considerably by subject area. The annual cost is estimated to be $472 million.

Introduction: Peripherally Inserted Central Catheters (PICCs) are commonly used in medium or long-term infusion therapy. This study aims to assess the costs associated with PICCs and its determinants. Methods: A retrospective cohort of patients with PICCs inserted at the Hospital for Sick Children between Jan.1, 2008 and Dec.31, 2008, were reviewed and followed until their PICCs were removed. Cost analysis, theoretical cost comparison with peripheral intravenous therapy (PIV), and multiple linear regressions were applied from the societal perspective. Findings: The average total cost is $2763.75/catheter/day, including inpatient ward cost. Age, male, ward, home care, catheter dwell days, and complications were found to be significant factors influencing the total cost. PICCs can become a cost saving device, compared to PIV, but is affected by several factors. Conclusion: Information gleaned from this study will inform decision makers maximizing the benefits of better resource allocation.

University of Technology, Sydney. Faculty of Design, Architecture & Building. / Past analyses of design solutions for building projects have concentrated on initial capital costs, often to the extent where the effects of subsequent operating costs are completely ignored. However, even in cases where a wider view of cost has been adopted, the discounting process has commonly disadvantaged future expenditure so heavily as to make performance after the short term irrelevant to the outcome, resulting in projects which display low capital and high operating costs to be given favour. Thus design solutions that aim to avoid repetitive maintenance, reduce waste, save nonrenewable energy resources or protect the environment through selection of better quality materials and systems, usually having a higher capital cost, are often rejected on the basis of the discounting process. Furthermore, the formulation of the discount rate has normally lacked rigour and has often resulted in an assumed rate that has implied profit and risk and has ignored taxation. Discounted present value is a measure of equivalence for time-phased costs and benefits derived from consideration of the theoretical investment return, preferably after tax. As it takes account of the cost of money, discounting can be described as leading to the determination of equivalent value using an investment-based or capital productivity approach. It is hypothesized and verified that the value of future costs and benefits is additionally susceptible to fluctuations in their base worth over time as reflected by changes in incremental escalation and the affordability of goods and services between present and future generations. Making adjustments for changes in worth may thus be described as contributing to the determination of equivalent value using a prosperity-based or time preference approach. The analysis of Australian sectorial income and expenditure data over a forty-year period shows that affordability changes can be measured and represented as an index. The discount rate is identified as a combination of the real weighted cost of capital, differential price level changes and diminishing marginal utility, where the latter is depicted by changes in the affordability of goods and services. This results in a composite discount rate that encompasses project-related, product-related and investor-related attributes. Tangible (financial) costs and benefits are discounted by this rate while intangible (environmental and social) costs and benefits are left as real value. Recommendations concerning the determination of equivalent value should ensure that the future operating performance of projects is more equitably assessed and that sustainable development remains an achievable objective in life-cost studies.
