Given the high rate of construction accidents, employers are not entirely mindful of the actual costs of construction accidents, especially when considering the hidden or indirect costs. The costs of construction accidents values presented in this study reveal that construction accidents present a substantial cost to employers and to society at large, inclusive of both, the direct and indirect costs. Robin Pillay attempts to establish the accumulated costs of construction related health and safety accidents given that occupational accidents and their associated costs are a serious concern, fundamentally for management and the construction industry at large. Further, accidents have huge cost implications that potentially affect not only overall project performance but the sustainability of the enterprise.
The first step to performance improvement is performance measurement. This is particularly true when seeking to improve the performance of the construction industry. This book presents an innovative approach to performance measurement based on the use of maturity modelling in conjunction with a set of project performance metrics. The maturity model, referred to as the CIM3, assesses the construction industry's maturity with respect to a set of industry practices. An industry practice leads to achievement of an objective, which in turn, leads to the realization of one of the construction industry's performance goals. Based on this, the CIM3 provides leading indicators of the construction industry's performance. These leading indicators can be used to predict the lagging performance of the construction industry, which is measured by project performance metrics. The use of the CIM3 in conjunction with a set of project performance metrics provides a holistic assessment of the performance of the construction industry. Based on this, policy makers are better informed with respect to performance improvement initiatives.
There is growing interest in future scenario planning of the construction industry but a disconnect between thinking about the future at the policy-making level and implementing real change. Constructing Futures: industry leaders and futures thinking in construction takes a thematic approach to the future of the UK construction industry by presenting the results of a series of in-depth interviews conducted with leading construction figures and structuring this material into chapters addressing the key contemporary issues in the industry. These high-profile figures are drawn from a wide range of stakeholder groups representing the realities of construction, including architects, client organisations (public-sector and private-sector), consultants, contractors, developers, lobby groups with special interests, policy makers, professional institutions, and trade unions. A total of 15 influential figures were interviewed for the book, from Sir Michael Latham and Bob White to Wayne Hemmingway and Kevin McCloud. Part One looks to the past by reviewing a series of foresight studies undertaken of the construction industry and re-presenting stories of our interviewees' lives to explain the development of leadership in the context of the construction industry. In Part Two, the authors look at the present and discuss two fundamental issues: sustainable development and governance of the construction industry. In Part Three the book concludes with an afterthought for the future, highlighting key lessons learnt putting forward a series of research questions derived from this scholarly reflection of 'futures thinking' in construction. Throughout, the authors juxtapose the views of the 15 influential figures interviewed with a review of the salient points found in the relevant and authoritative sources of theoretical literature, both in the mainstream literature and the field of construction management. This allows the reader to benefit from the practical insights of those interviews whilst gaining a rapid understanding of the key debates of the theoretical subject under scrutiny.
This work focuses on the performance analysis of a reduced switch three phase Z-source inverter fed cost effective induction motor drive system. In the proposed approach, instead of a conventional six switch three phase inverter a four switch three phase Z-source inverter is utilized. This reduces the cost of the inverter, the switching losses, and the complexity of the control algorithms. The new Z-source inverter system provides ride-through capability during voltage sags, reduces line harmonics, improves power factor, reliability and extends output voltage range. Validations of the theory and reduction methods are performed experimentally. This proposed method is able to reduce conduction noise in contrast with the existing conventional inverters. Analysis, simulation and experimental results are presented to demonstrate these new features.
The Irish economy collapsed in mid 2008 and with that was the once booming construction industry. Today the only large construction projects remaining are the Concession Roads that are been constructed throughout the country. However only a small proportion of the work is been carried out by Irish Contractors. Now, today with many Construction contractors out of work one has to question why Government funded work is not been solely completed by Irish contractors.
"Eugene Onegin" is the master work of the poet whom Russians regard as the fountain head of their literature. Set in 1820s Russia, Pushkin's verse novel follows the fates of three men and three women. Engaging, full of suspense, and varied in tone, it contains a large cast of characters and offers the reader many literary, philosophical, and autobiographical digressions, often in a highly satirical vein. "Eugene Onegin" was Pushkin's own favorite work, and this new translation by Stanley Mutchell conveys the literal sense and the poetic music of the original.
Effective project management in building construction always related to three major items that is time implication, cost implication and quality of the building construction. This book identified four most important causes to the ineffectiveness of project management in building construction which are design error, construction error, client change requirement and other factor which are mostly related to authority change requirement and no risk management implication. To achieve an effective project management in building construction , for primary stage, there are four main reasons need to be solved and PDCA ( Plan-Do-Check-Act) method have been proposed to help solve three major process of building construction that is pre-construction period, construction period and post-construction period.
This thesis is on the topic of set theory and in particular large cardinal axioms, singular cardinal patterns, and model theoretic principles in models of set theory without the axiom of choice (ZF). A standardised setup for the technique of our main tool, symmetric forcing, is established, in order to describe models that satisfy the approximation lemma. Sets of ordinals in such models are included in some model of set theory with the axiom of choice (ZFC). This enables the partial usage of previous knowledge about models of ZFC in the proofs. Most of the models are constructed using large cardinal strength and have cardinals with large cardinal properties. With the construction of such models it is shown that if we drop the axiom of choice from our requirements and assume a certain amount of large cardinal strength, several patterns of singular cardinals are possible and model theoretic properties such as higher Chang conjectures become much weaker in consistency strength. This thesis is written in a didactic style, in the hope that it will be useful for other researchers who want to use symmetric forcing with large cardinals for consistency strength studies.
Performance rating of contractors is very important to both the client and contractor especially in an emerging construction industry like the Ghanaian construction industry. Indeed, previous studies internationally have indicated that the development of a set of measurable criteria is key to performance rating. In the absence of any empirical data for legitimizing performance assessment in the Ghanaian Construction Industry, this book provides a set of criteria that could be applied in rating contractor performance in the Ghanaian construction industry. A survey was conducted in Ghana among professionals to identify a set of performance criteria that many think would be relevant and applicable for assessing the performance of contractors in the Ghanaian construction industry. Though, this book is based on the opinion of consultants within the industry, it is expected that the findings of this book could be relevant for future policy guidelines for rating contractor performance in Ghana.
The books takes a holistic picture of construction projects delays and cost overruns by examining real projects. The major causes of project delays and cost overruns have been identified on the basis of questionnaire survey from the major stakeholders, including contractors, designers, sponsors and project managers. The analysis has revealed that cost increases, time delays and poor quality are three major concerns in the construction projects of Higher Education Sector of Pakistan. In the economic analysis, the delayed part of the projects has been analyzed on the basis of actual costs from the real time cost data. The Construction Price Index has been calculated on the basis of increases in the costs of delayed items of work. The book is recommended for the graduate students of Construction and Project management. It is also useful for the undergraduate students to develop their perceptions about the project management. For the students in Pakistan, the book can provide valuable information about the factors leading to project delays and cost overruns of construction projects
The plate and frame filter press is one of the good devices for filtration on a large scale. Although many types of equipments have been designed since the introduction of the plate and frame filter press, still the extent of its applications and the number of units in use have grown steadily year after year. The reason for this growth has been the fact that a large proportion of the filtration problems of industry require the flexibility, high capacity, higher pressures, and rapidity of filtration cycle which are offered by this type of filter. The plate and frame filter press is most economical and most satisfactory for an extremely wide range of products requiring either clarification or the recovery of solids in suspension. In this work an attempt is made to study the performance of Plate and Frame filter press by varying various parameters influencing the effectiveness of the filter press. This work is aimed for utilization by researchers, industrialists’ and traditional businesses. Apart from this it will be especially relevant and useful for the students of Metallurgy, Mining and Chemical Engineering for carrying out research in the area of large scale filtration.
